Revisions and Additions to Motor
Vehicle Fuel Economy Label
Environmental Protection
Agency (EPA) and National Highway
Traffic Safety Administration (NHTSA),
Department of Transportation.
ACTION: Proposed rule.
AGENCY:
The Environmental Protection
Agency (EPA) and the National
Highway Traffic Safety Administration
(NHTSA) are conducting a joint
rulemaking to redesign and add
information to the current fuel economy
label that is posted on the window
sticker of all new cars and light-duty
trucks sold in the U.S. The redesigned
label will provide new information to
American consumers about the fuel
economy and consumption, fuel costs,
and environmental impacts associated
with purchasing new vehicles beginning
with model year 2012 cars and trucks.
This action will also develop new labels
for certain advanced technology
vehicles, which are poised to enter the
U.S. market, in particular plug-in hybrid
electric vehicles and electric vehicles.
NHTSA and EPA are proposing these
changes because the Energy
Independence and Security Act (EISA)
of 2007 imposes several new labeling
requirements, because the agencies
believe that the current labels can be
improved to help consumers make more
informed vehicle purchase decisions,
and because the time is right to develop
new labels for advanced technology
vehicles that are being commercialized.
This proposal is also consistent with the
recent joint rulemaking by EPA and
NHTSA that established harmonized
federal greenhouse gas (GHG) emissions
and corporate average fuel economy
(CAFE) standards for new cars, sport
utility vehicles, minivans, and pickup
trucks for model years 2012–2016.
DATES: Comments: Comments must be
received on or before November 22,
2010. Under the Paperwork Reduction
Act, comments on the information
collection provisions must be received

This action affects companies that
manufacture or sell new light-duty
vehicles, light-duty trucks, and
medium-duty passenger vehicles, as
defined under EPA’s CAA
regulations,1 2 and passenger
automobiles (passenger cars) and nonNAICS CodesA

Automobile dealers.
American Industry Classification System (NAICS).
In this joint proposal, there are many
issues common to both EPA’s and
NHTSA’s proposals. For the
convenience of all parties, comments
submitted to the EPA docket (whether
hard copy or electronic) will be
considered comments submitted to both
EPA and the NHTSA docket, and vice
versa. Therefore, the public only needs
to submit one set of comments to either
one of the two agency dockets that will
be reviewed by both agencies.
Comments that are submitted for
consideration by only one agency
should be identified as such, and
comments that are submitted for
consideration by both agencies should
be identified as such. Absent such
identification, each agency will exercise
its best judgment to determine whether
a comment is submitted on its proposal.
Further instructions for submitting
comments to either the EPA or NHTSA
docket are described below.
EPA: Direct your comments to Docket
ID No EPA–HQ–OAR–2009–0865. EPA’s
policy is that all comments received
will be included in the public docket
without change and may be made
available online at https://
www.regulations.gov, including any
personal information provided, unless
the comment includes information
claimed to be Confidential Business
Information (CBI) or other information
whose disclosure is restricted by statute.
Do not submit information that you
consider to be CBI or otherwise
protected through https://
www.regulations.gov or e-mail. The
https://www.regulations.gov Web site is
an ‘‘anonymous access’’ system, which
means EPA will not know your identity
or contact information unless you
provide it in the body of your comment.
If you send an e-mail comment directly
to EPA without going through https://
www.regulations.gov your e-mail
address will be automatically captured
and included as part of the comment
that is placed in the public docket and
made available on the Internet. If you
submit an electronic comment, EPA
recommends that you include your
name and other contact information in
the body of your comment and with any
disk or CD–ROM you submit. If EPA
cannot read your comment due to
technical difficulties and cannot contact
you for clarification, EPA may not be
able to consider your comment.
Electronic files should avoid the use of
special characters, any form of
encryption, and be free of any defects or
viruses. For additional information
about EPA’s public docket visit the EPA
Docket Center homepage at https://
www.epa.gov/epahome/dockets.htm.
NHTSA: Your comments must be
written and in English. To ensure that
your comments are correctly filed in the
1 ‘‘Light-duty vehicle,’’ ‘‘light-duty truck,’’ and
‘‘medium-duty passenger vehicle’’ are defined in 40
CFR 86.1803–01.
2 Generally, the term ‘‘light-duty vehicle’’ means a
passenger car, the term ‘‘light-duty truck’’ means a
pick-up truck, sport-utility vehicle, or minivan of
up to 8,500 lbs gross vehicle weight rating, and
‘‘medium-duty passenger vehicle’’ means a sportutility vehicle or passenger van from 8,500 to
10,000 lbs gross vehicle weight rating. Mediumduty passenger vehicles do not include pick-up
trucks.
3 ‘‘Passenger car’’ and ‘‘light truck’’ are defined in
49 CFR part 523.
This list is not intended to be
exhaustive, but rather provides a guide
regarding entities likely to be regulated
by this action. To determine whether
particular activities may be regulated by
this action, you should carefully
examine the regulations. You may direct
questions regarding the applicability of
this action to the person listed in FOR
FURTHER INFORMATION CONTACT.
B. Public Participation

Number NHTSA–2010–0087 in your
comments. Your comments must not be
more than 15 pages long.4 NHTSA
established this limit to encourage you
to write your primary comments in a
concise fashion. However, you may
attach necessary additional documents
to your comments. There is no limit on
the length of the attachments. If you are
submitting comments electronically as a
PDF (Adobe) file, we ask that the
documents submitted be scanned using
the Optical Character Recognition (OCR)
process, thus allowing the agency to
search and copy certain portions of your
submissions.5 Please note that pursuant
to the Data Quality Act, in order for the
substantive data to be relied upon and
used by the agencies, it must meet the
information quality standards set forth
in the OMB and Department of
Transportation (DOT) Data Quality Act
guidelines. Accordingly, we encourage
you to consult the guidelines in
preparing your comments. OMB’s
guidelines may be accessed at https://
www.whitehouse.gov/omb/

Tips for Preparing Your Comments
When submitting comments, please
remember to:
• Identify the rulemaking by docket
numbers and other identifying
information (subject heading, Federal
Register date and page number).
• Follow directions—The agencies
may ask you to respond to specific
questions or organize comments by
referencing a Code of Federal
4 49

identified in the DATES section above.
How do I submit confidential business
information?
Any confidential business
information (CBI) submitted to one of
the agencies will also be available to the
other agency.6 However, as with all
public comments, any CBI information
only needs to be submitted to either one
of the agencies’ dockets, and it will be
available to the other. Following are
specific instructions for submitting CBI
to either agency.
EPA: Do not submit CBI to EPA
through https://www.regulations.gov or
e-mail. Clearly mark the part or all of
the information that you claim to be
CBI. For CBI information in a disk or CD
ROM that you mail to EPA, mark the
outside of the disk or CD ROM as CBI
and then identify electronically within
the disk or CD ROM the specific
information that is claimed as CBI. In
addition to one complete version of the
comment that includes information
claimed as CBI, a copy of the comment
that does not contain the information
claimed as CBI must be submitted for
inclusion in the public docket.
Information so marked will not be
disclosed except in accordance with
procedures set forth in 40 CFR part 2.
In addition, you should submit a copy
from which you have deleted the
claimed confidential business
information to the Docket by one of the
methods set forth above.
NHTSA: If you wish to submit any
information under a claim of
confidentiality, you should submit three
copies of your complete submission,
including the information you claim to
be confidential business information, to

pursuant to 40 CFR 2.209(c) that EPA will share
confidential information received with NHTSA
unless commenters specify that they wish to submit
their CBI only to EPA and not to both agencies.

the Chief Counsel, NHTSA, at the
address given above under FOR FURTHER
INFORMATION CONTACT. When you send a
comment containing confidential
business information, you should
include a cover letter setting forth the
information specified in our
confidential business information
regulation.7 In addition, you should
submit a copy from which you have
deleted the claimed confidential
business information to the Docket by
one of the methods set forth above.
Will the agencies consider late
comments?
NHTSA and EPA will consider all
comments received before the close of
business on the comment closing date
indicated above under DATES. To the
extent practicable, we will also consider
comments received after that date. If
interested persons believe that any new
information the agency places in the
docket affects their comments, they may
submit comments after the closing date
concerning how the agency should
consider that information for the final
rule. However, the agencies’ ability to
consider any such late comments in this
rulemaking will be limited due to the
time frame for issuing a final rule.
If a comment is received too late for
us to practicably consider it in
developing a final rule, we will consider
that comment as an informal suggestion
for future rulemaking action.
How can I read the comments submitted
by other people?
You may read the materials placed in
the docket for this document (e.g., the
comments submitted in response to this
document by other interested persons)
at any time by going to https://
www.regulations.gov. Follow the online
instructions for accessing the dockets.
You may also read the materials at the
EPA Docket Center or NHTSA Docket
Management Facility by going to the
street addresses given above under
ADDRESSES.
How do I participate in the public
hearings?
NHTSA and EPA will jointly hold two
public hearings; one in Chicago on
October 14, 2010, and one in Los
Angeles on October 21, 2010, with both
daytime and evening sessions at each
location. EPA and NHTSA will
announce the specific hearing locations
and times of day in a separate Federal
Register announcement.
If you would like to present testimony
at the public hearings, we ask that you

persons listed under FOR FURTHER
INFORMATION CONTACT at least ten days
before the hearing. Once EPA and
NHTSA learn how many people have
registered to speak at the public hearing,
we will allocate an appropriate amount
of time to each participant, allowing
time for lunch and necessary breaks
throughout the day. For planning
purposes, each speaker should
anticipate speaking for approximately
ten minutes, although we may need to
adjust the time for each speaker if there
is a large turnout. We suggest that you
bring copies of your statement or other
material for the EPA and NHTSA panels
and the audience. It would also be
helpful if you send us a copy of your
statement or other materials before the
hearing. To accommodate as many
speakers as possible, we prefer that
speakers not use technological aids (e.g.,
audio-visuals, computer slideshows).
However, if you plan to do so, you must
notify the contact persons in the FOR
FURTHER INFORMATION CONTACT section
above. You also must make
arrangements to provide your
presentation or any other aids to
NHTSA and EPA in advance of the
hearing in order to facilitate set-up. In
addition, we will reserve a block of time
for anyone else in the audience who
wants to give testimony.
The hearing will be held at a site
accessible to individuals with
disabilities. Individuals who require
accommodations such as sign language
interpreters should contact the persons
listed under FOR FURTHER INFORMATION
CONTACT section above no later than ten
days before the date of the hearing.
NHTSA and EPA will conduct the
hearing informally, and technical rules
of evidence will not apply. We will
arrange for a written transcript of the
hearing and keep the official record of
the hearing open for 30 days to allow
you to submit supplementary
information. You may make
arrangements for copies of the transcript
directly with the court reporter.

I. Overview of Joint EPA/NHTSA
Proposal on New Vehicle Labels
mstockstill on DSKH9S0YB1PROD with PROPOSALS3
A. Summary of and Rationale for
Proposed Label Changes
This joint action by the
Environmental Protection Agency (EPA)
and the National Highway Traffic Safety
Administration (NHTSA) proposes what
will likely be the most significant
overhaul of the federal government’s
fuel economy label or ‘‘sticker’’ since its
inception over 30 years ago.
The current fuel economy label
required on all new passenger cars,
light-duty trucks, and medium-duty
passenger vehicles contains the
following core information, as required
by statute:
• City and highway fuel economy
values in miles per gallon.
• Comparison of the vehicle’s
combined city/highway fuel economy to
a range of comparable vehicles.
• Estimated fuel cost to operate the
vehicle for one year.
This joint proposal is designed to
update the current label in order to
increase the usefulness of the label in
helping consumers choose more
efficient and environmentally friendly
vehicles that would also meet new
requirements added by Congress. This
proposal also includes new label
designs for electric vehicles (EVs) and
plug-in hybrid electric vehicles
(PHEVs), two advanced vehicle
technologies that are beginning to enter
the market.
EPA and NHTSA are co-proposing
two label designs for public comment
without a single primary proposal,
although the final rule will adopt only
one label design. Both label designs
meet statutory requirements and rely on
the same underlying data; they differ in
how the data is used and presented on
the label. One is a more traditional label
design that retains the current label’s
focus on fuel economy values and
annual fuel cost projections, with a
general label layout more similar to the
current label. The second label design
contains all appropriate information but
VerDate Mar<15>2010
18:48 Sep 22, 2010
Jkt 220001
prominently features a letter grade to
communicate the overall fuel economy
and greenhouse gas emissions—along
with projected 5-year fuel cost or
savings associated with a particular
vehicle when compared to an average
vehicle. The agencies are also seeking
comment on an alternative third label
design that follows a more traditional
format but presents some information
differently. All labels expand upon the
content found on the current label and
include the following information for
conventional vehicles (advanced
technology vehicle labels contain
additional information tailored to the
individual technology):
• City and highway fuel economy
values in miles per gallon.
• Combined city/highway fuel
consumption in gallons per 100 miles.
• Tailpipe carbon dioxide (CO2)
emissions in grams per mile.
• Annual fuel cost in dollars per year.
• A slider bar comparing the
combined fuel economy to all other
vehicles.
• A slider bar comparing the CO2
emissions to all other vehicles.
• A slider bar comparing non-CO2
(‘‘other’’ or ‘‘smog-related’’) emissions to
all other vehicles.
• A symbol that can be read by a
‘Smartphone’ for additional consumer
information (also known as a QR
Code®).
• A reference to a Federal government
Web site for additional information.
Despite the fact that the co-proposed
labels are based on the same underlying
data, they are significantly different in
terms of presentation and prominence.
The agencies encourage public feedback
on the central question of which label
design would be more useful and help
consumers select more energy efficient
and environmentally friendly vehicles
that meet their needs, or whether the
agencies should consider alternative
designs.
NHTSA and EPA are proposing these
changes because the Energy
Independence and Security Act (EISA)
of 2007 mandates several new labeling
requirements intended to help
consumers make more informed vehicle
purchase decisions, and because this is
an appropriate time to develop new
labels for advanced technology vehicles
(Battery Electric or EVs and Plug-In
Hybrid Vehicles or PHEVs) that are
being commercialized. The agencies
believe that a joint label meeting our
separate statutory requirements and our
shared consumer information objectives
makes far more sense for both
consumers and manufacturers than
separate labels. As a joint rulemaking,
PO 00000
Frm 00006
Fmt 4701

this proposal is also consistent with the
recent joint rulemaking by EPA and
NHTSA that established harmonized
federal greenhouse gas (GHG) emissions
and corporate average fuel economy
(CAFE) standards for new cars, sport
utility vehicles, minivans, and pickup
trucks for model years 2012–2016.8
The agencies believe these new
labeling requirements for automobiles
are important in light of a growing
national interest in both fuel economy
and climate change. Historically,
consumers have generally paid the most
attention to fuel economy when fuel
prices increase sharply over a short
period of time, such as in 2008, but the
agencies believe that this phenomenon
has changed and consumers will
continue in the future to pay more
attention to fuel economy. Based on
projections from the U.S. Energy
Information Administration that future
gasoline prices will increase over
coming decades due to global economic
growth and oil demand, we believe that
it is likely that consumer interest in and
use of the fuel economy label will grow
over time.9 In addition, given the
increased awareness of consumers
regarding climate change and air
pollution, more comprehensive
information on the emissions
performance of vehicles, as required by
EISA, could help consumers make more
informed decisions on how a vehicle
they buy may impact the environment.
It is also important for the agencies to
define labeling requirements for
advanced vehicle technologies that are
nearing commercialization. The existing
label has long provided city and
highway fuel economy in terms of miles
per gallon (MPG) values, which the
agencies believe are well recognized and
understood by consumers, and which
are widely used as metrics for
comparing the efficiency of one vehicle
to another. Since the late 1970s when
the fuel economy label was first
established by EPA as required under
the Energy Policy Conservation Act
(EPCA) of 1975, over 99 percent of the
automobiles sold have been
conventional, internal-combustion
engine vehicles that run on petroleumbased fuels (or a liquid fuel blend
dominated by petroleum). When
manufacturers produced different
advanced technology vehicles, such as
compressed natural gas vehicles, EPA
has generally addressed the need for
labels on a case-by-case basis.

Over the next several model years,
however, the agencies expect to see
increasing numbers of EVs and PHEVs
entering the marketplace. This proposal
includes changes to the label to address
some of the specific issues raised by the
use of grid electricity as a fuel for EVs
and PHEVs. These vehicles will be
required to display labels containing the
same kind of information as
conventional vehicles, but some of that
information may be better conveyed in
different ways, and consumers may be
interested in different information for
these vehicles. For example, evaluating
the performance of a vehicle that uses
grid electricity as some or all of its fuel,
or the cost of operating such a vehicle,
presents unique challenges for making
an informed comparison between
different EVs and PHEVs, and between
advanced technology vehicles and their
conventional vehicle counterparts
including gasoline and diesel fueled
vehicles and hybrid gasoline electric
vehicles (HEVs).
The co-proposed label designs present
two approaches for addressing the
complex challenges associated with
labels for these advanced technology
vehicles, and the agencies encourage the
public to comment on a wide range of
possible solutions. The agencies
recognize that this is only the first
generation of EV and PHEV labels, and
we expect to refine them over time as
we have done with conventional vehicle
labels. Additionally, the agencies
recognize that other advanced
technology vehicles, such as fuel cell
vehicles (FCVs), may enter the
marketplace in the near future as well,
but for purposes of this first effort we
have chosen to focus on EVs and
PHEVs. Specific label requirements for
other advanced technology vehicles will
be developed at a later time as those
vehicles enter the market.
This joint proposal is designed to
satisfy each agency’s statutory
responsibilities in a manner that
maximizes usefulness for the consumer,
while avoiding unnecessary burden on
the manufacturers who prepare the
vehicle labels. Since 1977, EPA has
required auto manufacturers to label all
new automobiles,10 pursuant to EPCA.11
As amended, EPCA requires that labels
shall contain the following information:
(1) The fuel economy of the
automobile;
10 An ‘‘automobile’’ is defined for these purposes
as a ‘‘4-wheeled vehicle that is propelled by fuel,
or by alternative fuel, manufactured primarily for
use on public streets, roads, and highways’’ and
‘‘rated at not more than 8,500 pounds gross vehicle
weight.’’ See 49 U.S.C. 32901(a)(3) and 32908(a)(1).
11 Public Law 94–163.
VerDate Mar<15>2010
18:48 Sep 22, 2010
Jkt 220001
(2) The estimated annual fuel cost of
operating the automobile;
(3) The range of fuel economy of
comparable vehicles of all
manufacturers;
(4) A statement that a booklet is
available from the dealer to assist in
making a comparison of fuel economy of
other automobiles manufactured by all
manufacturers in that model year;
(5) The amount of the automobile fuel
efficiency tax (‘‘gas guzzler tax’’)
imposed on the sale of the automobile
under section 4064 of the Internal
Revenue Code of 1986 (26 U.S.C. 4064);
and
(6) Other information required or
authorized by the EPA Administrator
that is related to the information
required by (1) through (4) above.12
In the Energy Independence and
Security Act of 2007 (EISA),13 Congress
required that NHTSA, in consultation
with EPA and the Department of Energy
(DOE), establish regulations to
implement several new labeling
requirements for new automobiles.14
NHTSA must develop a program that
requires manufacturers to label new
automobiles with information reflecting
an automobile’s performance with
respect to fuel economy and greenhouse
gas and other emissions over the useful
life of the automobile based on criteria
provided by EPA.15 NHTSA must also
develop a rating system that makes it
easy for consumers to compare the fuel
economy and greenhouse gas and other
emissions of automobiles at the point of
purchase, including designations of
automobiles with the lowest GHG
emissions over the useful life of the
vehicles, and the highest fuel
economy.16
Thus, either the basic label for
automobiles needs to be expanded to
include additional information on
performance in terms of fuel economy,
greenhouse gas and other emissions, or
a new label needs to be required.
NHTSA and EPA believe that a joint
rulemaking to combine all of these
elements into a single revised fuel
economy label is the most appropriate
way to meet the goals described above,
rather than placing the information in
two separate labels with duplicative and
overlapping information, which could
cause consumer confusion and impose
unnecessary burden on the
manufacturers.17

Finally, given the goals described
above and the need to provide
additional information on the label, the
agencies believe that the overall vehicle
label design format and content should
be reevaluated and could be improved.
Simply including the additional
information required under EISA for
both conventional and advanced
technology vehicles necessitates a
review of the overall label design.
As described above, the agencies view
the purpose of the label as providing
information that will be most useful for
consumers in making informed
decisions regarding the energy
efficiency and emissions impacts of the
vehicles they purchase. Providing
information on energy, environmental
performance, and cost can educate
consumers in various ways. These
metrics have the potential to help
people who value this kind of
information to make a more informed
choice among different vehicles. It also
has the potential to inform people who
currently place less or even no value on
this kind of information, but who may
decide it is more important to them at
some point in the future. NHTSA and
EPA are mindful that this is a
complicated issue and that there is no
readily ascertainable metric to
determine whether we have achieved
this somewhat subjective and
qualitative purpose. Therefore, EPA and
NHTSA are co-proposing two options,
and also taking comment on another
alternative, that highlight a number of
relevant issues on which we seek public
comment. The agencies will consider all
public comments and publish a final
rule in the near future.
B. A Comprehensive Research Program
Informed the Development of Proposed
Labels
Since today’s proposal includes
adding important new elements to the
existing label as well as creating new
labels for advanced technology vehicles,
EPA and NHTSA embarked on a
comprehensive and innovative research
program beginning in the fall of 2009.
The research helped inform the
development of the new labels being
proposed and included three phases of
consumer focus groups, a review of
available literature, and a day-long
consultation with an expert panel of
individuals who have introduced new
products or have spearheaded national
educational campaigns.
For the focus groups, the agencies
decided to use a three-phase approach
rulemaking for MYs 2012–2016 CAFE and GHG
standards for light-duty vehicles, 75 FR 25324 (May
7, 2010).

Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
in order to accommodate the sheer
amount of information intended to be
covered in the groups, as well as to use
each phase to inform the next phase to
help evolve the overall label design in
regard to both content and appearance.
Focus groups were held beginning in
late February through May 2010 in four
cities: Charlotte, Houston, Chicago, and
Seattle. Overall, 32 focus groups were
convened with a total of 256
participants. We asked the focus groups
about the following issues:
• How they use the current fuel
economy label,
• What feedback they could give us
on potential new information and
metrics for the label for conventional
and advanced technology vehicles (EVs
and PHEVs), and
• What feedback they could give us,
after reviewing draft labels, on designs
and the level of information that makes
sense, as well as overall preference for
displaying information.
The insights received from the focus
groups were key for the agencies with
regard to individual metrics that
consumers wanted to see on labels and
also with regard to effective label
designs. Overall, focus groups
indicated 18 that redesigned labels must:
• Create an immediate first
impression for consumers.
• Be easy to read and understand
quickly.
• Clearly identify vehicle technology
(conventional, EV, PHEV).
• Utilize color.
• Chunk information to allow people
to deal with ‘‘more information.’’
• Be consistent in content and design
across technologies.
• Allow for comparison across
technologies.
• Make it easy to identify the most
fuel efficient and environmentally
friendly vehicles.
Following the focus group research,
we assembled an expert panel for a one
day consultation and asked them to give
us feedback on the draft label designs
the focus groups had helped create and
to also assist us in identifying
opportunities and strategies to provide
more and better information to
consumers so that they can more easily
assess the costs, emissions, and energy
efficiency of different vehicles. The
experts came from a variety of fields in
advertising and product development,

and were chosen because they have led
successful national efforts to introduce
new products or have spearheaded
national educational campaigns. After
viewing the draft labels, the expert
panel offered the agencies the following
insights and guidance 19 that were key
in developing one of the co-proposed
label designs, including:
• Keep it simple; we yearn for
simplicity (fewer, bigger, better).
• Consumers don’t act on details.
• Remember the reality of very short
label viewing time—roll ratings and
metrics up into a single score.
• Use cost savings information- a very
strong consumer motivator.
• Develop a Web site that would be
launched in conjunction with the new
label. This consumer-focused, user
friendly Web site would provide more
specific information on the label
including additional information on the
letter grade, along with access to the
tools, applications, and social media.
Beyond these two core research
elements, the agencies also undertook a
comprehensive literature review 20 and
drafted and had peer reviewed an
internet survey. The agencies intend to
administer the survey concurrently with
the release of this proposal, and the
results will be made publicly available
in the dockets for this proposal prior to
issuing a final rule with the new label
requirements.
The agencies also met with a number
of stakeholders, including
environmental organizations, auto
manufacturers, and dealers, to gather
their input on what the label should and
should not contain, as well as to
ascertain particular concerns.21
Comments received on labeling issues
in the context of the joint rulemaking on
fuel economy and GHG standards,22 as
well as for the 2006 fuel economy
labeling rule,23 have also been
considered.
C. When would the proposed label
changes take effect?
The agencies propose that the final
label changes will take effect for model

year (MY) 2012 vehicles, consistent
with the recent joint rulemaking by EPA
and NHTSA that established
harmonized federal GHG emissions and
CAFE standards for new cars, sport
utility vehicles, minivans, and pickup
trucks for model years 2012 through
2016.24 For those advanced technology
vehicles that will be introduced to the
market prior to MY2012, EPA will work
with individual manufacturers on a
case-by-case basis to develop interim
labels under EPA’s current regulations
that can be used prior to MY2012 and
that are consistent with the proposed
labels for advanced technology vehicles.
D. What are the estimated costs and
benefits of the proposed label changes?
The primary costs associated with this
proposed rule come from revisions to
the fuel economy label and new testing
requirements. As discussed in Section
VII of this preamble, we estimate that
the costs of this rule are likely to be in
the range of $649,000—$2.8 million per
year. This rule is not economically
significant under Executive Order 12866
or any DOT or EPA policies and
procedures because it does not exceed
$100 million or meet other related
standards.
The primary benefits associated with
this proposed rule come from any
improvements in consumer decisionmaking that may lead to reduced vehicle
and fuel costs for them. There may be
additional effects on criteria pollutants
and greenhouse gas emissions. At this
time, EPA and NHTSA do not believe it
is feasible to fully develop a complete
benefits analysis of the potential
benefits.
EPA and NHTSA request comment on
the assessment of the benefits and costs
presented in Section VII below.
E. Relationship of This Proposal to
Other Federal and State Programs
This proposal involves the addition of
new information and design changes to
conventional vehicle labels and the
creation of specific labels for certain
advanced vehicle technologies, but will
not impact other important elements of
the Federal government’s fuel economy
and GHG emissions regulatory
programs. For example, this proposal
will not affect the fuel economy
compliance values used in NHTSA’s
CAFE program, or the GHG emissions
compliance values used in EPA’s GHG
emissions control program. Nor will this
proposal affect the methodology by
which EPA generates the consumer fuel
economy values used on the vehicle
labels and provided at https://

www.fueleconomy.gov. The result of the
additional information, including
environmental information, appearing
on the label will necessitate that
additional information also be displayed
on this Web site in the future. Finally,
this proposal does not affect the test
procedures that are used by EPA and
manufacturers to generate the Federal
government’s vehicle fuel economy and
GHG emissions database.
This proposal also does not affect the
vehicle labels required by the California
Air Resources Board which indicate
relative ratings for ‘‘Smog’’ and ‘‘Global
Warming,’’ in fulfillment of that state’s
statutory requirements. The agencies are
aware that the California labels provide
information that is effectively
duplicative with some of the
information on the labels that will result
from this rulemaking effort, although
using different underlying rating
methodologies and presentational
approaches. It is the hope of both
NHTSA and EPA that the Federal label
can meet the CARB requirements and,
thus, preclude the need for a separate
set of labels. However, it is ultimately
up to California to determine how to
implement its statute and, thus, beyond
the purview of this rulemaking to make
any such determination.

F. History of Federal Fuel Economy
Label Requirements
The fuel economy label has evolved
several times since it was first required
by Congress in the 1970s, both in
response to new statutory requirements
and to changing policy objectives. There
have been important changes in the past
to make the label more technically
accurate and understandable to
consumers. The changes being proposed
are consistent with past efforts by EPA
to make the fuel economy label more
consumer friendly and effective over
time. This section provides a brief
historical summary of the development
of the fuel economy label.
The Energy Policy and Conservation
Act of 1975 (EPCA) established two
primary fuel economy requirements: (1)
Fuel economy information, designed for
public use, in the form of fuel economy
labels posted on all new motor vehicles,
and the publication of an annual booklet
of fuel economy information to be made
available free to the public by car
dealers; and (2) calculation of a
manufacturer’s average fuel economy
and compliance with a standard (later,
this compliance program became known
as the Corporate Average Fuel Economy
(CAFE) program). The responsibilities
for these requirements were split
between EPA, the Department of
VerDate Mar<15>2010
18:48 Sep 22, 2010
Jkt 220001
Transportation (DOT) 25 and the
Department of Energy (DOE). EPA is
responsible for establishing the test
methods and procedures both for
determining the fuel economy estimates
that are displayed on the labels and in
the annual booklet, and for the
calculation of a manufacturer’s
corporate average fuel economy. DOT,
and by delegation, NHTSA, is
responsible for administering the CAFE
compliance program, which includes
establishing standards, determining
compliance, and assessing any penalties
as needed. DOE is responsible for
publishing and distributing the annual
fuel economy information booklet.
EPA published regulations
implementing portions of the EPCA
statute in 1976.26 The provisions in this
regulation, effective with the 1977
model year, established the first fuel
economy label along with the
procedures to calculate fuel economy
values for labeling and CAFE purposes
that used the Federal Test Procedure
(FTP or ‘‘city’’ test) and the Highway
Fuel Economy Test (HFET or ‘‘highway’’
test) data as the basis for the
calculations. At that time, the
fundamental process for determining
fuel economy was the same for labeling
as for CAFE, except that the CAFE
calculations combined the city and
highway fuel economy values into a
single number for manufacturers’
compliance purposes.27
After a few years of public exposure
to the fuel economy estimates on the
labels of new vehicles, it soon became
apparent that drivers were disappointed
by not often achieving these estimates
on the road and expected them to be as
accurate as possible. In 1978, Congress
recognized the concern about
differences between EPA-estimated fuel
economy values and actual consumer
experience and mandated a study under
section 404 of the National Energy
Conservation Policy Act of 1978.28 In
February 1980, a set of hearings were
conducted by the U.S. House of
Representatives Subcommittee on
Environment, Energy, and National
Resources. One of the recommendations
in the subsequent report by the
25 The CAFE-related responsibilities of the
Secretary of Transportation are delegated to the
NHTSA Administrator at 49 CFR 1.50.
26 41 FR 38685, promulgated at 40 CFR part 600.
27 EPCA requires that manufacturers simply
comply with passenger car and light truck CAFE
standards, it does not require separate city and
highway standards for each type of automobile.
Thus, EPA calculates the average fuel economy for
a manufacturer by weighting and combining the
results of each automobile on the separate city and
highway cycles. See 49 U.S.C. 32904(c).

Subcommittee was that ‘‘EPA devise a
new MPG system for labeling new cars
and for the Gas Mileage Guide that
provides fuel economy values, or a
range of values, that most drivers can
reasonably expect to experience.’’ 29
EPA commenced a rulemaking
process in 1980 to revise its fuel
economy labeling procedures, and
analyzed a vast amount of in-use fuel
economy data as part of that
rulemaking.30 In 1984, EPA published
new fuel economy labeling procedures
that were applicable to 1985 and later
model year vehicles.31 The decision was
made to retain the FTP and highway test
procedures, primarily because those
procedures were also used for other
purposes, including emissions
certification and CAFE determination.
Based on the in-use fuel economy data,
however, it was evident that the final
fuel economy values put on the labels
needed to be adjusted downward in
order to reflect more accurately
consumers’ average fuel economy
experience. The final rule, therefore,
included downward adjustment factors
for both the city and highway label fuel
economy estimates. The city values
(based on the raw FTP test data) were
adjusted downward by 10 percent and
the highway values (likewise based on
the raw highway test data) were
adjusted downward by 22 percent.32
In the early 2000s, EPA again began
investigating the accuracy of the fuel
economy label estimates, and concluded
that driving behavior (e.g., higher
average speed and acceleration) and
other factors (such as the use of ethanol
as a gasoline blending agent) had
changed significantly since the
correction factors were implemented in
1985, leading again to a widening gap
between real-world fuel economy and
the label estimates that consumers saw
when shopping for new vehicles. During
the development of vehicle emissions
regulations in the late 1990s, EPA had
already conclusively found that the city
and highway tests did not adequately
represent real-world driving, and in
December of 2006 EPA finalized new

test methods for calculating the fuel
economy label values.33
The 2006 final rule made three
important changes. First, EPA’s new
methods brought the miles per gallon
estimates closer to consumers’ actual
fuel economy by including factors such
as high speeds, quicker accelerations,
air conditioning use, and driving in cold
temperatures. These revised fuel
economy estimates also reflect other
conditions that influence fuel economy,
like road grade, wind, tire pressure,
load, and the effects of different fuel
properties. The new estimates took
effect with model year 2008 vehicles.
Second, EPA now requires fuel
economy labels on certain heavier
vehicles up to 10,000 pounds gross
vehicle weight, such as larger SUVs and
vans. Manufacturers will be required to
post fuel economy labels on these
vehicles beginning with the 2011 model
year. Third, to convey fuel economy
information to the public more
effectively, EPA updated the design and
content of the label. The rule required
that new labels be placed on vehicles
manufactured after September 1, 2007.
The fuel economy for each vehicle
model continues to be presented to
consumers on the label as city and
highway MPG estimates.

1. Energy Policy and Conservation Act
(EPCA)
Under EPCA, EPA is responsible for
developing the fuel economy labels that
are posted on all new light duty cars
and trucks sold in the U.S. and
beginning in MY 2011 all new medium
duty trucks as well. Medium-duty
passenger vehicles are a subset of
vehicles between 8,500 and 10,000
pounds gross vehicle weight that
includes large sport utility vehicles and
vans, but not pickup trucks. EPCA
requires the manufacturers of
automobiles to attach the fuel economy
label in a prominent place on each
automobile manufactured in a model
year and also requires auto dealerships
to maintain the label on the
automobile.34
EPCA specifies the information that is
minimally required on every fuel
economy label.35 As stated above, labels
must include:
• The fuel economy of the
automobile,
• The estimated annual fuel cost of
operating the automobile.

• The range of fuel economy of
comparable automobiles of all
manufacturers,
• A statement that a booklet is
available from the dealer to assist in
making a comparison of fuel economy of
other automobiles manufactured by all
manufacturers in that model year,
• The amount of the automobile fuel
efficiency tax imposed on the sale of the
automobile under section 4064 of the
Internal Revenue Code of 1986; 36 and
• Other information required or
authorized by the Administrator that is
related to the information required
[within the first four items].
Under the provision for ‘‘other
information’’ EPA has previously
required the statements ‘‘your actual
mileage will vary depending on how
you drive and maintain your vehicle,’’
and cost estimates ‘‘based on 15,000
miles at $2.80 per gallon’’ be placed on
vehicle labels.
There are additional labeling
requirements found in EPCA for
‘‘dedicated’’ automobiles and ‘‘dual
fueled’’ automobiles. A dedicated
automobile is an automobile that
operates only on an alternative fuel.37
Dedicated automobile labels must also
display the information noted above.
A dual fueled vehicle is a vehicle
which is ‘‘capable of operating on
alternative fuel or a mixture of biodiesel
and diesel fuel, and on gasoline or
diesel fuel’’ for the minimum driving
range (defined by the DOT).38 Dual
fueled vehicle labels must:
• Indicate the fuel economy of the
automobile when operated on gasoline
or diesel fuel.
• Clearly identify the automobile as a
dual fueled automobile.
• Clearly identify the fuels on which
the automobile may be operated; and
• Contain a statement informing the
consumer that the additional
information required by subsection
(c)(2) [the information booklet] is
published and distributed by the
Secretary of Energy.39
EPCA defines ‘‘fuel economy’’ for
purposes of these vehicles as ‘‘the

U.S.C. 4064.
U.S.C. 32901(a)(1) defines ‘‘alternative fuel’’

subsection (b) of this section, a mixture containing
at least 85 percent of methanol, denatured ethanol,
and other alcohols by volume with gasoline or other

(G) hydrogen; (H) coal derived liquid fuels; (I) fuels
(except alcohol) derived from biological materials;
(J) electricity (including electricity from solar
energy); and (K) any other fuel the Secretary of
Transportation prescribes by regulation that is not
substantially petroleum and that would yield
substantial energy security and environmental
benefits.’’

Additionally, EPA is required under
EPCA to prepare a fuel economy booklet
containing information that is ‘‘simple
and readily understandable.’’ 41 The
booklet is commonly known as the
annual ‘‘Fuel Economy Guide.’’ EPCA
further instructs DOE to publish and
distribute the booklet. EPA is required
to ‘‘prescribe regulations requiring
dealers to make the booklet available to
prospective buyers.’’ 42 While the
booklet continues to be available in
paper form, in 2006, EPA finalized
regulations allowing manufacturers and
dealers to make the Fuel Economy
Guide available electronically to
customers as an option.43
2. Energy Independence and Security
Act (EISA)
The 2007 passage of the Energy
Independence and Security Act (EISA)
amended EPCA by introducing
additional new vehicle labeling
requirements, to be implemented by the
National Highway Traffic Safety
Administration (NHTSA).44 While EPA
retained responsibility for establishing
test methods and calculation procedures
for determining the fuel economy
estimates of automobiles for the purpose
of posting fuel economy information on
labels and in an annual Fuel Economy
Guide, NHTSA gained responsibility for
requiring automobiles to be labeled with
additional performance metrics and
rating systems to help consumers
compare vehicles to one another more
easily at the point of purchase.
Specifically, and for purposes of this
rulemaking, subsection ‘‘(g) Consumer
Information’’ was added to 49 U.S.C.
32908. Subsection (g), in relevant part,
directed the Secretary of Transportation
(by delegation, the NHTSA
Administrator) to ‘‘develop and
implement by rule a program to require
manufacturers—to label new
automobiles sold in the United States
with information reflecting an
automobile’s performance on the basis
of criteria that the [EPA] Administrator
shall develop, not later than 18 months
after the date of the of the Ten-in-Ten

final rule consistent with the agencies’
final decisions on label formats and
based on review and consideration of all
public comments.
The new single label is the result of
EPA and NHTSA’s decision that it is
good public policy to consolidate label
requirements called for by EPCA and
EISA. This label would contain
information not only on a new vehicle’s
fuel economy, annual fuel cost, and
range of fuel economy within class, but
also, for the first time, information on a
new vehicle’s fuel consumption,
emissions, and comparative rating
information, as required by statute. This
expansion of the role of the label
beyond fuel economy information
reflects the new EISA requirements,
which are premised on the concept that
greenhouse gas and other environmental
information is also in the public
interest.
In developing this proposal, the
agencies came up with two distinct
approaches for conveying information
on the label. While both approaches rely
on the same underlying data and both
meet EPCA and EISA requirements, they
differ in how they present and
emphasize the information. One
approach is more traditional, focusing
primarily on MPG values and
secondarily on annual fuel cost, but
adding new elements, such as
environmental information. A label
using this approach would look familiar
to the public, with a style similar to the
45 Current hybrid vehicles obtain their electric
power from their onboard conventional gasoline
engine and energy captured through regenerative
braking. Thus, the vehicle’s energy source is still
gasoline.
46 Definitions for hybrid electric vehicles, electric
vehicles, fuel cell vehicles, and plug-in hybrid
electric vehicles can be found in EPA regulations
at 40 CFR 86.1803–01.

II. Proposed Revisions to the Fuel
Economy Label Content (Metrics and
Rating Systems)
This section discusses the elements
that the agencies are proposing for the
fuel economy label. Section A discusses
the range of options considered and
proposed for ‘‘conventional’’ petroleumfueled vehicles (i.e., those powered
solely by gasoline or diesel fuel).
Current hybrid vehicles, which are
fundamentally gasoline-fueled
vehicles,45 will continue to use the same
label as other gasoline vehicles, just as
they do today. Many of the approaches
discussed in Section A, such as the
rating systems, will apply across all
vehicles, including advanced
technology vehicles. Section B
specifically discusses the special cases
of advanced technology vehicles. These
vehicles—such as electric vehicles (EVs)
and plug-in gasoline-electric hybrid

vehicles (PHEVs) 46—are one of the key
reasons we are proposing new
regulations. The agencies are concerned
that current label requirements do not
adequately address these vehicles, and
we are seeking to develop labels that are
useful and understandable to
consumers, as well as equitable across
the range of different vehicles and
technological approaches. Section C
addresses some of the less common
fuels and fuel combinations for which
label templates must ultimately be
developed, such as compressed natural
gas and methanol.
A. Conventional Gasoline, Diesel and
Hybrid Vehicles
The complete effect of this proposal
would be a single new label, which
replaces the existing fuel economy label
and which contains more information
than is currently displayed, even in the
case of conventional petroleum-fueled
vehicles. An example of the current
label is shown here to provide a basis
for comparison with the proposed
labels.

automobile: a rating system that would
make it easy for consumers to compare
the fuel economy and greenhouse gas
and other emissions of automobiles at
the point of purchase, including a
designation of automobiles— with the
lowest greenhouse gas emissions over
the useful life of the vehicles; and the
highest fuel economy * * *’’
Thus, both EPA and NHTSA have
authority over labeling requirements
related to fuel economy and
environmental information under EPCA
and EISA, respectively. In order to
implement that authority in the most
coordinated and efficient way, the
agencies are jointly proposing the
revised labels presented below. NHTSA
notes that its proposed regulatory text
changes to 49 CFR Chapter V to
implement the EISA requirements (and
to make other proposed changes) are
currently designated as ‘‘reserved.’’ This
is not to suggest that these sections will
remain ‘‘reserved’’ (i.e., blank) for the
final rule. NHTSA will add regulatory
text to implement the EISA
requirements in these sections for the
mstockstill on DSKH9S0YB1PROD with PROPOSALS3
58088
Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
existing label. Requiring a label based
on the traditional approach assumes
that potential vehicle purchasers will
use the information that is most
meaningful to them, whether that is
MPG, fuel cost, or other values. For
example, participants in the focus
groups leading up to this proposal
indicated that, when considering the
current fuel economy label, nearly all
used the city and highway MPG values
almost exclusively, despite the presence
of other data elements on the label;
some also used annual fuel cost and
within-class comparison information.47
The other approach uses the same
data, but shifts the emphasis to a single,
more prominent value that reflects fuel
consumption and its counterpart,
greenhouse gas emissions, using a
format the consumers will easily
recognize—a letter grade. The associated
numerical values and other required
elements would remain on the label, but
with much less prominence. This
approach makes it simpler for the
consumer to identify those vehicles that
use less oil and have a lesser
environmental impact and more clearly
expands the role of the label beyond
fuel economy information. Many of the
focus group participants indicated that
they trusted the EPA to determine
which of these factors were important,
and the agencies believe that consumers
might be more likely to consider a
vehicle with higher fuel economy and
lesser environmental impact if they
were provided with a simpler label.48
The agencies believe each approach
has merit and that the public will be
well-served by having both be fully
considered; therefore, EPA and NHTSA
are co-proposing two label designs
based on these two approaches, without
either being the primary proposal.
NHTSA and EPA expect that comments
will provide valuable insight on these
two proposed label designs, and seek
comment on the merits and drawbacks
of each, recognizing that the label
design ultimately finalized may draw on
elements from all the labels presented in
this proposal. The labels are presented
in Section III. Label designs 1 and 2 are
co-proposed, with Label 1 being the
letter grade approach and Label 2 being
the more traditional approach. Label 3,
on which comment is also sought, is an
alternative version of the traditional
approach.

the labels, how the agencies considered
them, and how we are proposing that
they be displayed on each of the coproposed labels.
1. Fuel Economy Performance
Since 1977, the EPA fuel economy
label has represented the fuel economy
performance of a vehicle with estimates
of city and highway miles per gallon
(MPG). With more than 30 years of
consumers seeing these estimates as the
most prominent values displayed on the
fuel economy labels, it is not surprising
that the consumer research conducted
as part of this rulemaking has revealed
a strong attachment to city and highway
MPG values. A combined city and
highway MPG value was first placed on
the label starting with model year
2008—as part of the graphic showing
the combined MPG value of the vehicle
compared with other vehicles in the
same class 49 but, even prior to this, the
combined MPG value has always been
a key input to estimating the annual fuel
cost value required on the label.50
Representing the vehicle’s fuel
economy performance on the label with
an estimate of miles per gallon is a core
element of the fuel economy
information requirements of EPCA,
which specifically states that the label
must display ‘‘the fuel economy of the
automobile’’ and defines ‘‘fuel economy’’
as ‘‘the average number of miles
travelled * * * for each gallon of
gasoline.’’ 51 In addition, EPA and
NHTSA have determined that
continuing to display the fuel economy
values on the label would also meet the
new requirements put in place by EISA
that call for a label ‘‘reflecting an
automobile’s performance [based on
criteria determined by EPA] to reflect
fuel economy * * * over the useful life
of the vehicle.’’ 52 Because vehicle fuel
economy depends primarily on
fundamental vehicle design
characteristics that do not change over
time, the agencies believe that fuel
economy remains essentially stable
throughout the life of properlymaintained vehicles. Thus the agencies
believe that the current test methods
that determine label values for new
vehicles will meet the EISA
49 The vehicle classes are defined in EPA
regulations at 40 CFR 600.315–08 and provide a
basis for comparing a vehicle’s fuel economy to that
of other vehicles in its class as required by statute.
See the discussion in section VI.C for a detailed
discussion of the vehicle class structure.
50 Combined fuel economy is a harmonic average
of the City and Highway MPG values, with the City
value weighted 55% and the Highway value
weighted 45%. See 71 FR 77904, December 27,
2006.

requirements by providing reasonable
estimates of fuel economy performance
for the full useful life of a vehicle.
Finally, consumers have shown a strong
familiarity with and preference for MPG
values, and have consistently indicated
that these values are used as part of the
vehicle purchase decision.
For these reasons, the agencies are
proposing to continue to provide mile
per gallon estimates to consumers, but
with some changes relative to the
current label, and with markedly
different approaches on the two coproposed labels.
The agencies recognize that the focus
group research suggested that
consumers have a strong familiarity
with and preference for the city and
highway fuel economy values 53
(although this preference was much
stronger for conventional vehicles than
for advanced technology vehicles; in
those cases perhaps the complexity of
the labels encouraged them to part with
some of the numbers on the label).
Focus group participants who argued
strongly for separate city and highway
MPG values on the label often stated, for
example, that most of their driving is
either city or highway, and that a
combined city-highway MPG value
might make it harder for them to
determine what MPG they should
reasonably expect for that vehicle.54 The
agencies believe that this apparent
preference was formed in large part
because of EPA’s decision to present
these as the dominant figures on the
label for decades, not because
consumers demanded these metrics 33
years ago. Had EPA been presenting the
combined number as the dominant
figure on the label since 1977, we might
expect to see a great deal of familiarity
with and understanding of that
particular value today. However, the
distinction between city and highway
driving does not address the key
variables that could impact energy
consumption for alternative
technologies, such as ambient
temperature. Thus, the agencies believe
that, for labeling purposes, the city/
highway distinction may be a less
relevant metric than in the past.
Thus with Label 1, NHTSA and EPA
propose that the MPG values be
significantly reduced in prominence
(i.e., smaller font and ‘‘below the fold’’
location on the label), with the letter
grade rating assuming the predominant
role. Given space constraints and the

since it is the metric that consumers are
the most familiar with and have come
to utilize on the label. However, it
downplays the separate city and
highway value in favor of a single,
combined MPG, because the agencies
believe that continuing to highlight
multiple pieces of fuel economy
information with the same level of
prominence could make it more difficult
for consumers to compare vehicles,
particularly across technology types,
where MPG becomes a less meaningful
metric. A similar approach is taken on
Label 3.
The agencies seek comment generally
on these two approaches to displaying
fuel economy performance information
on the labels. Specifically, comment is
sought on whether or not the labels that
emphasize combined city/highway MPG
values over separate city and highway
MPG values are helpful to consumers,
and why or why not. If combined MPG
is preferred, comment is sought on
whether or not city and highway values
should continue to be displayed, and
why or why not.
2. Fuel Consumption
While miles per gallon is statutorily
mandated for fuel economy labels and
has appeared on the label for several
decades, the agencies have some
concern that it can be a potentially
PO 00000
Frm 00013
Fmt 4701
Sfmt 4702
misleading comparative tool for
consumers, particularly when it is used
as a proxy for fuel costs. The problem
can be easily illustrated by the following
figure, which shows the non-linear
relationship between gallons used over
a given distance and miles per gallon. It
can be seen that the difference in
gallons it takes to go 1,000 miles
between 10 and 15 MPG (about 33
gallons) is substantially greater than the
difference in gallons it takes to go the
same distance between 30 and 35 MPG
(about 5 gallons). In other words, even
if consumers clearly understand that
higher MPG is better, those comparing
vehicles with relatively low MPG values
may not know that MPG differences that
appear to be small, even one or two
MPG, may actually have very different
fuel consumption values, and that
selecting the slightly higher MPG
vehicle could actually result in
significantly less fuel used, thus saving
a considerable amount of money. Fuel
consumption numbers, unlike MPG,
relate directly to the amount of fuel
used. Mathematically, they represent
gallon per mile, instead of miles per
gallon. Not coincidentally, they also
relate directly to the amount of CO2
emitted, because the grams of CO2
produced are directly proportional to
gallons of fuel combusted.
E:\FR\FM\23SEP3.SGM
23SEP3
EP23SE10.003
mstockstill on DSKH9S0YB1PROD with PROPOSALS3
amount of information that is required
to be provided on the label, continuing
to display MPG estimates with the same
or similar prominence would be likely
unnecessary and possibly untenable.
The city and highway MPG values
would be available for those who wish
to use them, but the rating assumes the
key role of informing the public about
the relative energy use and carbon
emissions of a vehicle. The agencies
believe that this de-emphasis on MPG
values would have two primary
benefits: First, the rating’s
predominance should encourage
consumers to use it rather than the
specific MPG values to compare across
vehicle technology types (particularly as
MPG values become less meaningful for
vehicles that do not run, or only
partially run, on fuels dispensed by the
gallon); and second, to address the nonlinearity of MPG with respect to energy
use, emissions, and cost, discussed
further in Section II.A.2, which becomes
more important as significantly higher
mileage vehicles are poised to enter the
marketplace.
The agencies are proposing a different
approach for Label 2, in which the
combined MPG value is displayed
prominently, with separate city and
highway values continuing to be shown
on the label, but as subordinate values.
This approach focuses attention on MPG

This so-called ‘‘MPG illusion,’’ which
has been widely written about by a
number of economists to illustrate why
MPG is a flawed measure of how a
vehicle’s efficiency relates to fuel
costs,55 was raised as an issue during
the development of the 2006 fuel
economy labeling rule. Some vehicle
manufacturers suggested at the time that
it may be more meaningful to express
fuel efficiency in terms of consumption
(e.g., gallons per mile or per 100 miles)
rather than in terms of economy (miles
per gallon).56 Fuel consumption is the
primary metric used in Europe, and the
Canadian fuel economy labels report
both MPG and a consumption metric
(liters per 100 kilometers). Because a
few stakeholders expressed an interest
in a fuel consumption metric at the
time, EPA requested comments on a
gallons-per-mile metric and how it
could be best used and presented
publicly, such as whether it should be
included in the Fuel Economy Guide.
The comments received in response to
this request were mixed. Public Citizen,
on the one hand, responded that, while
there may be some merit to including a
fuel consumption metric, consumers are
comfortable with MPG. Any change,
they argued, should be carefully
deliberated and involve a massive
public outreach campaign to educate
consumers.57 They also suggested that
the estimated annual fuel cost provides
information derived from consumption
values and is thus a suitable proxy for
consumption. Toyota, in contrast,
commented that fuel consumption is a
more meaningful measure than MPG for
expressing fuel efficiency, while
acknowledging EPA’s statutory
limitations. They noted—as have many
others—that the MPG metric is
fundamentally nonlinear in relation to
issues of consumer interest, such as cost
of fuel or gallons used, and noted that
anecdotal evidence shows that the
nonlinear aspects of MPG can lead to
consumer confusion. Toyota concluded
that ‘‘* * * this is a matter on which the
EPA is obligated to educate the public
as fuel consumption, not fuel economy,

is a direct reflection of the
environmental impact of vehicles in
use.’’ 58
EPA responded to these comments in
the 2006 final rule by concluding that
switching to a consumption metric
without a long-term consumer
education program would cause
confusion and that, absent
Congressional action, the fuel economy
labels would still have to continue to
report MPG. EPA also agreed with
commenters that the estimated annual
fuel cost was a consumption-based
metric which conveys essentially the
same information (although the
estimated annual fuel cost on the label
is not without its own limitations, as
described below).
To allow further consideration of this
issue, the consumer focus groups
conducted for this rulemaking were
asked to specifically explore the MPG
illusion. Most participants were
unconvinced that consumption should
be included on the label with primary
prominence and, although many were
unopposed to having it as additional
information, it was unclear whether it
would add value from their
perspective.59 This was the case
regardless of the consumption metric
tested, ranging from gallons per 100
miles to annual gallons consumed.
However, there is general interest
from a number of parties in the
inclusion of a fuel consumption metric
on the label. The agencies, as well,
believe that it is important to introduce
the concept of consumption to enable
consumers to more accurately consider
fuel use and costs during the vehicle
purchase process. Thus, the agencies
propose to introduce such a metric
along with the MPG values, expecting
that, over time, and with some
education, consumers will begin to
understand energy consumption and the
direct connection it has with the fuel
costs and environmental impacts of the
vehicle. EPA is therefore proposing to
include an estimate of gallons per 100
miles on the label under its 49 U.S.C.
32908(b)(1)(F) authority to require other
information related to fuel economy on
the label, and requests comment on
doing so, as well as on alternative
options for reflecting fuel consumption,
such as annual gallons consumed.60 For

consumers to use a consumption
number, however, EPA and NHTSA
believe that a comprehensive education
campaign would have to accompany the
roll-out of new labels.
The agencies also seek comment on
the specifics of displaying a
consumption metric on the two labels
being co-proposed. Although the label
may provide city and highway MPG
values as well as a combined city/
highway MPG, we are proposing to
require only the combined city/highway
consumption value on the label. The
agencies are concerned that requiring a
consumption value corresponding to
every MPG value would lead to an
undesirable proliferation of numbers on
the label.
3. Greenhouse Gas Performance
In addition to the fuel economy
performance information that has been
provided on the labels since 1977,
Congress directed NHTSA, through
EISA, to require new vehicles to also be
labeled with information reflecting their
greenhouse gas performance, which
would be determined on the basis of
criteria provided by EPA to NHTSA. As
with fuel economy, the GHG
performance information would be per
vehicle model type. EPA hereby
proposes the criteria for determining
greenhouse gas performance, addressing
the greenhouse gases to be incorporated,
the emissions sources to include, the
underlying test procedures, and the
specific metric to be used. The agencies
seek comment on whether these criteria,
as described below, are reasonable and
appropriate for determining the
greenhouse gas performance of new
vehicles. For purposes of this NPRM,
NHTSA is proposing that the
greenhouse gas performance element of
the label be based on these criteria.
These same greenhouse gas performance
values would also be used as the basis
for the proposed greenhouse gas rating
systems.
With regard to the greenhouse gases to
be covered, the agencies propose that
the label include greenhouse gas
performance information solely on the
basis of carbon dioxide (CO2) emissions,
which typically constitute
approximately 95% of the tailpipe
emissions of greenhouse gases.
Including emission levels of the
greenhouse gases methane (CH4) and
nitrous oxide (N2O) along with CO2
would not provide additional
differentiation between vehicles. This is
because, for purposes of compliance
with EPA’s GHG standards beginning in
model year 2012, CH4 and N2O values
would be based on emission factors–that
is, set values applied to each vehicle,

mstockstill on DSKH9S0YB1PROD with PROPOSALS3
Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
rather than direct measurements.
Because these values would be set at the
same level for all vehicles, the agencies
do not believe that including them
would provide consumers with
additional useful information.
Similarly, the agencies propose that
the greenhouse gas information be based
on CO2 emissions for the vehicle model
type, rather than the carbon-related
exhaust emissions (CREE) methodology
used to determine fuel consumption for
CAFE programs and compliance with
the light duty greenhouse gas
requirements. The use of CREE adds a
level of complexity that, while useful
for compliance purposes, may not be
beneficial to public understanding of
the relative differences in GHG
emissions between vehicles because the
levels of other carbon-related emissions
are low relative to CO2 emissions.
Although the agencies propose that the
greenhouse gas information on the label
be based only on CO2, we also seek
comment on whether and, if so, how,
the other greenhouse gases and carbonrelated emissions should be included.
Regarding the underlying test
procedures to be used to determine the
vehicle-specific GHG performance
information for the labels, the agencies
propose that the CO2 values presented
on the label be based on the five-cycle
test procedures that are currently
utilized for fuel economy labeling
purposes.61 These test procedures
measure rates of tailpipe CO2 and other
emissions, which form the basis of the
fuel economy values currently used for
vehicle labeling. The five-cycle test
procedures have been used for labeling
since model year 2008, and have
significantly improved the correlation
between label values for MPG and those
seen in actual use. Manufacturers could
thus calculate CO2 emission rates using
the same approach that they use for
label fuel economy values, which the
agencies know to be well-correlated
with actual performance in use. More
specifically, if a manufacturer uses the
‘‘derived five cycle’’ method for
determining MPG for fuel economy
labeling, they would use the same
method for determining CO2 for labeling
purposes. The city and highway CO2
emissions test results would then be
used in the derived five-cycle equations,
which the EPA has converted from a
MPG basis to a CO2 basis for this
purpose. Similarly, vehicle model types
that are using the ‘‘full five cycle’’
method for fuel economy labeling
would use the CO2 results from those
tests for purposes of fuel economy
labeling. The agencies are therefore

proposing that manufacturers use the
same five-methodology currently
utilized for fuel economy labeling
purposes for determining GHG values
for purposes of the new label.
As far as emission sources to include,
NHTSA and EPA propose that the
greenhouse gas emissions represented
on the label include only vehicle
tailpipe emissions,62 and do not account
for any GHG emissions generated
upstream of the vehicle. This approach
is also consistent with the vehicle GHG
emissions compliance levels recently
adopted by EPA, which treat GHG
emissions for electric operation as zero
up to a cumulative production cap per
manufacturer.63
When exploring this issue with focus
groups, the agencies found that most
participants did not consider the issue
of upstream emissions either way. A few
raised it when they noted that an
electric vehicle indicated zero
emissions, and suggested that these
vehicles did cause some emissions at
the power plant, which should be
represented on the label.64 On further
discussion, they generally determined
that it would be challenging for the label
to meaningfully represent the range of
emissions from power plants operated
on different fuels, and suggested that
this information was obtainable from
other sources.65 Given space constraints
and the difficulty of explaining the
potential range of upstream emissions
due to different fuel sources,
participants tended to agree that this
issue could be adequately addressed by
a statement on the label indicating that
the CO2 values on the label represented
vehicle tailpipe emissions only. The
label designs presented in this NPRM
include the words ‘‘Tailpipe Only’’ next
to the CO2 value presented; the agencies
seek comment on whether this wording
will be readily and uniformly
understood to mean that upstream GHG
emissions are not being reflected on the
label, or whether other, more direct
62 The agencies seek comment on the potential
inclusion of GHG emissions reflecting from A/C
leakage credits, as described later in this section.
63 EPA placed a cumulative production cap on the
total production of EVs, PHEVs, and FCVs for
which an individual manufacturer can claim the
zero grams/mile compliance value during model
years 2012–2016. The cumulative production cap
will be 200,000 vehicles, except that those
manufacturers that sell at least 25,000 EVs, PHEVs,
and FCVs in MY 2012 will have a cap of 300,000
vehicles for MY 2012–2016. See 75 FR 25436 (May
7, 2010).

wording might be clearer and more
helpful to consumers.
Aside from tailpipe CO2, the agencies
are not proposing, but seek comment on
the inclusion of an additional factor in
the GHG performance used for labeling:
air conditioning (A/C) credits generated
by a manufacturer under the light duty
vehicle GHG requirements. Air
conditioning (A/C) systems contribute
to GHG emissions in two ways.
Hydrofluorocarbon (HFC) refrigerants,
which are powerful GHGs, can leak
from the A/C system (direct A/C
emissions). Operation of the A/C system
also places an additional load on the
engine, which results in additional CO2
tailpipe emissions (indirect A/C related
emissions). The efficiency-related A/C
impacts are accounted for in the fivecycle tests utilized for fuel economy
labeling and proposed as the basis for
GHG labeling purposes. However, EPA
and NHTSA are considering whether
allowing manufacturers that generate
credits towards their GHG compliance
obligation by reducing A/C leakagerelated GHGs should be allowed to
factor these credits into the CO2 value
displayed on the label and used as the
basis for the GHG rating. Allowing
manufacturers to factor A/C credits into
the GHG performance metric on the
label would reward them for making
A/C leakage improvements, but it would
also cause the GHG performance value
and the fuel economy performance
value to diverge, and would impact the
methodology for any rating system that
combines GHGs and fuel economy.
Because A/C-related reductions are not
‘‘tailpipe,’’ including leakage
improvements in the tailpipe emissions
could be misleading and inaccurate. If
the final label includes other nontailpipe emissions, the agencies may
consider incorporating A/C leakage
improvements. EPA and NHTSA seek
comment on a number of issues:
whether including A/C leakage
adjustments would lead to widening the
gap between what is on the label and
what consumers get in the real world;
whether and, if so, how, to allow the use
of A/C credits for the purposes of
labeling, with specific focus on the
methodology and how the labels might
display the inclusion of A/C leakage
credits if the agencies decided to allow
their use.
EPA and NHTSA are proposing to use
grams per mile as the metric to display
greenhouse gas performance
information on the label, which would
be consistent with the metric used for
GHG emission standards and
compliance for light duty vehicles. The
agencies believe that this metric is also
consistent with requirements in 49

This variation—absolute rating
scales—directly utilizes the actual fuel
economy and CO2 performance values
per vehicle model type to define the
rating, which the agencies believe has
both potential benefits and drawbacks.

constant, but they may not remain
exactly constant. The agencies therefore
seek comment on how significant this
potential for inaccuracy could be on
consumers’ ability to use the absolute
rating scales to compare fuel economy
and GHG emissions across vehicles, and
on whether commenters believe the
labels would have to be revised in order
to meet the statutory requirement every
time a new ‘‘best’’ vehicle was
introduced if they were not
accommodated by the end points.
The second approach to a rating
system is also displayed on Label 1: A
combined rating scale for fuel economy
and GHG emissions, shown in the form
of a letter grade. Because vehicles that
are low in CO2 emissions have
inherently good fuel economy (and vice
versa), and because CO2 emissions are
the primary determinant of fuel
economy using EPA test procedures,
vehicles would generally tend to have
the same ‘‘score’’ for fuel economy as for
GHG emissions. Thus, if the ratings are
equivalent, as a practical matter, it
would be consistent with the statutory
requirement to provide a single,
combined rating system.
The proposed letter grade scale would
range from A+ to D, including plus and
minus designations to provide more
opportunities for improvement. All
vehicles would receive a ‘‘passing’’
grade—that is, the ratings would not
include an ‘‘E’’ or ‘‘F’’ grade—because all
vehicles must meet CAA requirements
in order to be sold, and the agencies do
not wish to convey otherwise.
Additionally, the ‘‘A+’’ vehicles—with
associated text stating the range of letter
grades—will indicate which vehicles are
the ‘‘best,’’ thus, meeting the
requirement that the label designate
highest fuel economy and lowest
greenhouse gas vehicles.
This variation of a fuel economy and
greenhouse gas rating system was
suggested by the expert panel and was
not presented in focus groups, but many
focus group participants favored the
simplification of information presented
when possible, and the agencies believe
that such a well-known rating approach
will be immediately recognizable by the
majority of consumers. The agencies are
also hopeful that a rating system as
simple as a letter grade may encourage
consumers to rely more on the rating
system itself in making purchasing
decisions, rather than on, for example,
MPG numbers, which are subject to the
‘‘MPG illusion’’ issue discussed above.
A letter grade allows vehicles
purchasers to make a comparative
assessment among vehicles with
different grades, consolidating
information so that consumers might
E:\FR\FM\23SEP3.SGM
23SEP3
Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
more easily assess the GHG emissions
and fuel economy of different vehicles
and make fully informed decisions. The
agencies also request comment on
whether any vehicle should receive a
grade of A+ or whether this might lead
to mistaken consumer conclusion that
the vehicle has no energy or
environmental impacts.
As noted above, CO2 emissions are
directly measured by EPA and form the
basis for calculating the fuel efficiency
of the vehicle; using CO2 as the basis for
the rating is the most direct
methodological approach and will avoid
any rounding discrepancies that could
occur from converting to MPG and then
to fuel consumption. It also avoids the
need to adjust the MPG thresholds by
fuel type to account for differences in
the energy content of fuel. Utilizing CO2
as the controlling factor in the rating
thresholds is a practical consideration
and is not meant to imply that GHG
emissions are more important than
energy use; both are relevant
considerations and are viewed by the
agencies as equally important under the
rating system.70
The agencies propose to base this
rating system approach on the range of
CO2 emissions for the projected fleet,
placing the middle of the rating scale at
the combined 5-cycle CO2 emissions
rate for the median vehicle,71 with
equal-sized increments of CO2 assigned
to each grade or rating.72 The higherGHG end of the scale would therefore be
twice the CO2 emissions rate of the
median value, although, effectively, any
vehicle higher than this level would
also receive the lowest rating. Under
such an approach, the median value
would become more stringent over time
as a result of GHG emissions
requirements and, thus, the entire scale
would shift toward lower GHG levels.
Unless a vehicle model reduced its rate
of CO2 emissions across the model
years, its ratings would gradually drop
over time. This approach would be
consistent with both the evolution of
fuel economy and emission
requirements, and the public
expectation that products evolve over
time. The CO2 thresholds associated
with each rating would be determined
on an annual basis and provided
through guidance in advance of the
model year. EPA would require that
manufacturers use the ratings from the
58093
prior year if they are in a position to
need to label a vehicle before the annual
guidance has been issued. The agencies
recognize that revising the median
baseline vehicle each year may lead to
some consumer confusion, but this
dilemma is no different than what
consumers currently encounter when
they view identical vehicles from
different model years and their
associated annual fuel cost or the
comparative fuel economy slider bar for
each vehicle displayed on today’s label.
The agencies continue to believe that
the underlying assumptions need to be
up-to-date to be most useful to
consumers. Nevertheless, the agencies
request comment on what the agencies
might do to avoid potential confusion.
The following example is based on
model year 2010 data and assumes that
one or more vehicles that emit zero CO2
tailpipe emissions (i.e., electric or fuel
cell vehicles) have entered the market.
Gasoline-equivalent MPG values are
provided in the table for clarity.
However, the agencies propose that the
CO2 values be controlling for purposes
of assigning the rating.

70 The direct relationship between CO and fuel
2
consumption breaks down to some extent for
vehicles with electric operation. For these vehicles,
tailpipe CO2 emissions are zero; however, energy is
consumed by the vehicle and an energy efficiency
value other than infinity can be assigned.
Nevertheless, given that electric drive trains are
currently much more efficient than those for
conventional vehicles, the relationship between
those vehicles emitting zero CO2 and having the
highest energy efficiency holds true at the present
time. This approach may need to reassessed in the
future if efficiencies of electric drive and
conventional vehicles begin to approach each other,
or if it is desired to differentiate between the
efficiencies of electric-powered vehicles, but should
not be a necessary consideration in the foreseeable
future.
71 Median vehicle is determined by vehicle model
type, with model type as defined in 40 CFR
600.002–08.
72 The agencies evaluated several potential
methodologies for creating this rating system
besides equal increments of CO2. We rejected an
approach that would create the rating system based
on establishing equal size categories for the ratings
using miles per gallon—that is, taking the range of
MPG of the vehicle fleet and dividing that range
into ten equal segments. Given that the fleet will
soon see vehicles that achieve MPG-equivalent
values of 75 to 100, the agencies were concerned
that this methodology would create a situation
where a vehicle such as the 2010 Toyota Prius
(which gets a combined MPG of 50 MPG) would
receive only an average rating. Using this method
would result in the vast majority of vehicles
receiving a rating well below the middle rating,
which would not seem to be an appropriate result
of a rating system. However, the agencies seek
comment on whether a combined rating system
based on MPG instead of on CO2 might be
developed in a way that avoided these results.
73 The additional vehicles are examples of types
expected to enter the commercial market. The CO2
and MPGe values shown are examples only and are
not based on any formal testing or certification data.

One potential issue with this
approach is that a rating system based
on CO2 emissions may not be an
adequate proxy for a fuel economy
rating system if the agencies decide in
the final rule to allow manufacturers to
use A/C credits in determining their
CO2 emissions values. Since fuel
economy by definition does not account
for HFC leakage, a CO2 rating boosted by
A/C leakage credits would not
accurately represent the vehicle’s fuel
economy rating. EISA requires that
labels include a rating system that
allows consumers to compare fuel
economy across vehicles, so a fuel
economy rating system that includes
HFC leakage arguably would not meet
these requirements. The proposed Label
1 would address this issue,
whether A/C were included in the
letter-grade rating or not, by virtue of
also having the absolute rating scale for
fuel economy at the bottom of the label.
Still, the agencies seek comment on
whether a rating system that combined
fuel economy and CO2 emissions could
accurately describe both if A/C credits
were permitted to be included in the
rating system for CO2.
Another issue with using a CO2-based
method is the fact that some diesel
vehicles would see their rating reduced
by 1⁄2 letter grade—i.e., diesel vehicles
would appear ‘‘worse’’ to the consumer
in the rating system—relative to an
approach that relied on MPG or fuel
consumption, given the higher carbon
content of a gallon of diesel fuel
compared to a gallon of gasoline. This
could potentially discourage some sales
of diesel vehicles if consumers are
influenced by the rating system, which
the agencies may not necessarily want
to accomplish. However, because a
consistent basis is needed across all
fuels, MPGe would need to be used
rather than MPG: This would provide
equivalency on an energy basis rather
than a volume basis, and would allow
the use of an MPG-type metric across
fuels that are not dispensed by the
gallon, such as CNG and electricity.
Since gasoline, diesel, biodiesel, and
VerDate Mar<15>2010
18:48 Sep 22, 2010
Jkt 220001
ethanol have nearly equivalent ratios of
energy to carbon, the choice of MPGe
versus CO2/mile has minimal impact on
the rating system results, particularly for
liquid fuels. The agencies nevertheless
seek comment on how significantly a
CO2-based rating system might impact
diesel sales, and whether an MPGebased rating system might ameliorate
any such impact, and if so, how that
rating system would need to be
structured for technology neutrality.
In practical terms, this means that the
rating system would include all vehicles
for which fuel economy information and
labeling is required, which currently
includes all passenger automobiles and
light trucks as defined by NHTSA at 49
CFR part 523. More specifically, the
rating system would span all
automobiles up to 8,500 pounds gross
vehicle weight, plus some vehicles
(large SUVs and some passenger vans)
between 8,500 and 10,000 pounds gross
vehicle weight. We believe that this is
consistent with the intent of Congress,
based on the text of EISA which refers
clearly to labels for ‘‘automobiles’’ rather
than ‘‘passenger’’ or ‘‘non-passenger
automobiles,’’ and which states that the
rating system must include a
designation of the vehicle with the
highest fuel economy and lowest GHG
emissions.74 The approach of including
all vehicles in a single rating system is
supported by the market research and
literature reviews done for this
proposal, which show that, while
prospective vehicle purchasers narrow
their choices by vehicle type early in the
buying decision, they do not focus
narrowly on a single class, at least as
defined by EPA. Focus group
participants indicated that they
shopped, on average, across two to three
vehicle classes.75 For these consumers,
a single rating system will enable them
to make accurate vehicle comparisons
across whichever vehicles they choose
to shop. Market research also indicates

that consumers have varying definitions
of what constitutes a specific vehicle
class, thus making it challenging to
categorize vehicles in a way that is
useful for all consumers.
Nevertheless, EPA is seeking
comment on rating passenger cars
separately from light duty trucks under
its authority to require other
information related to fuel economy as
authorized by the Administrator at 49
U.S.C. 32908(b)(1)(F).76 In this case,
EPA would propose to use the same
definitions for cars and trucks used for
light-duty fuel economy and GHG
standards, which are NHTSA’s
definitions provided in 49 CFR part 523.
Doing so would be consistent with
automaker obligations under those
requirements, in which cars and trucks
have separate sets of standards.
Additionally, market research shows
that, while many people shop across
several narrowly-defined classes, about
two-thirds shop exclusively among
either trucks or cars. These consumers
might find it useful to compare among
only those vehicles of interest. If a
commenter believes that separate rating
systems for cars and trucks would be
preferable, EPA especially seeks
comment on whether those consumers
that shop among both cars and trucks
could adequately compare across their
vehicles of interest if ratings systems
were separated, and whether or not the
emerging ‘‘crossover’’ market will make
this ‘‘car/truck’’ distinction increasingly
less relevant and potentially confusing
to the public.77
76 NHTSA does not interpret 49 U.S.C.
32908(g)(1)(A)(ii) as permitting rating systems based
on less than the entire fleet, so a rating system for
fuel economy and/or GHG emissions based on only
the car or truck fleet would not be sufficient to
satisfy EISA’s requirement, although EPA could
require such a rating system under its authority.
77 For example, under NHTSA’s and EPA’s
definitions, the same version of a crossover could
potentially be a ‘‘car’’ if it were two wheel drive and
a ‘‘truck’’ if it were four wheel drive. A consumer
looking at the labels of these two vehicles side by
side might find it challenging to understand why
their ratings were different.

5. Other Emissions Performance and
Rating System
In addition to fuel economy and
greenhouse gas information and ratings,
EISA requires new vehicles to also be
labeled with information reflecting a
vehicle’s performance in terms of ‘‘other
emissions,’’ and a rating system that
would make it easy for consumers to
compare the other emissions of
automobiles at the point of purchase.78
Unlike fuel economy and GHG
emissions, EISA does not expressly
require the designation of the ‘‘best’’
vehicle in terms of other emissions. This
section lays out the criteria that EPA
proposes NHTSA use to form the basis
for other emissions performance and
ratings. Concurrently, NHTSA proposes
that these criteria be used as the
foundation for information that is
provided on the label.
Congress did not precisely define in
EISA which of the pollutants in the
universe of possible candidates for
‘‘other emissions’’ should be included
for labeling purposes. The agencies
assume that Congress did not intend to
create any new substantive
requirements as part of this labeling
provision for pollutants that are not
currently regulated and, thus, propose
that ‘‘other emissions’’ include those
tailpipe emissions, other than CO2, for
which vehicles are required to meet
current emission standards. These air
pollutants comprise both criteria
emissions regulated under EPA’s
National Ambient Air Quality Standards
and air toxics, and include:
• NMOG—non-methane organic
gases;
• NOX—oxides of nitrogen;
• PM—particulate matter;
• CO—carbon monoxide; and
• HCHO—formaldehyde.
Auto manufacturers must provide the
agency with emission rates of these
pollutants for all new light duty
vehicles each model year under EPA’s
Tier 2 light duty vehicle emissions
standards requirements,79 or the parallel
requirements for those vehicles certified
instead to the California emissions
standards.80 Emission standards for
these pollutants are aggregated into
bins; each bin contains emissions limits
on a gram per mile basis for each of the
aforementioned pollutants for the useful
life of the vehicle, as shown in Table
II.A.5–1. To be eligible for sale in the
United States, each vehicle model and
configuration must be certified to a
specific bin, meaning that the
automaker is confirming that the vehicle
is designed not to exceed the specified
emission rates for any of the pollutants
over the useful life of the vehicles.
Automakers must submit data to EPA
that demonstrates compliance with
these levels, with a requirement that
their fleet achieve a sales-weighted NOX
average equivalent to the Bin 5 standard
or cleaner annually. California and
states that have adopted California
emissions standards in lieu of the
federal standards have similar sets of
emissions standards, known as the Low
Emitting Vehicle II (LEV II) standards.81

The agencies considered whether to
provide specific information and ratings
for each of these individual pollutants
listed above. EPA Tier 2 emission
regulations do require manufacturers to
submit specific information regarding
the performance of each vehicle for each
of these pollutants, but the agencies
believe that attempting to require all of
it to be represented on the fuel economy
label, along with rating systems for
each, would be unduly burdensome and
not reasonable given space constraints
and the need to present all the other
information required by EPCA and
EISA.

interest in actual emissions levels across
multiple pollutants was minimal, and
this level of detail is likely to be well
beyond that which most members of the
public would seek or find useful.82
Repeatedly, focus group participants
reflected that it was the job of the
government to determine the relative
importance of the pollutants, and that
the label should not leave this
determination up to the individual.
Given that EISA did not specify exactly
which pollutants would make up ‘‘other
emissions’’ and given focus group
feedback that differentiation between
other emissions did not add value for
many participants, the agencies are not
proposing to provide pollutant-specific
information on the label for ‘‘other
emissions.’’ Nevertheless, the agencies
seek comment on whether pollutantspecific information and ratings might
have value to consumers beyond what
the agencies have seen in their focus
group research, and if so, how the
agencies might design a label to require
pollutant-specific information and
ratings that would make it easy for
consumers to compare other pollutant
emissions across vehicles at the point of
purchase.
Instead, the agencies believe that a
rating based on the groups of emissions
standards—either the Federal Tier 2 bin
system or the California LEV II system,
as appropriate—can and should be used
requirements are met. 42 U.S.C. 7507, Clean Air Act
Section 177, allows states, under certain conditions,
to adopt California’s vehicle emission standards.

to meet this requirement. This approach
mirrors the current Air Pollution Score
on EPA’s Green Vehicle Guide (https://
www.epa.gov/greenvehicle). Vehicle
certification under either the Federal
Tier 2 bin system or the California LEV
II system allows auto manufacturers to
certify that their vehicles will fall into
an emissions range across each of the
regulated pollutants. In effect, the
Federal and California systems rate
vehicles according to their air pollution
emissions by compiling the
requirements across multiple pollutants
into one category (a Tier 2 bin or a LEV
II standard). Though these systems are
useful for regulatory compliance, they
have limited recognition among
consumers. However, relative rating
systems are well-recognized by the
public, and the Federal emissions bins
and California standards categories are
well-suited to conversion to a relative
rating system that would be readily
understandable.
58097
EPA and NHTSA therefore propose to
establish a rating system for ‘‘other
emissions’’ in which each rating is
associated with a bin from the Federal
Tier 2 emissions standards (or
comparable California emissions
standard). Table II.A.5–2 provides an
example of how such a system would
work for a ten-point rating scale.83
Various graphical representations of this
rating are being contemplated, as
discussed in Section III.

Because such a rating would be
directly reflective of the emissions
standards requirements for air
pollutants to which the vehicle is
certified, the agencies believe that it
could serve the dual purposes of
performance information and ratings for
‘‘other emissions’’ as required by 49
U.S.C. 32908(g)(1)(A)(i) and (A)(ii).
Such an approach would have the
advantage of avoiding requiring detailed
information on the label that would
detract from the key elements and could
be of minimal use to the majority of the
public. NHTSA and EPA seek comment
on whether also utilizing the rating
system to meet the requirement for
performance information on other
emissions would be permissible under
EISA.
6. Overall Energy and Environmental
Rating
One of the issues that came up
frequently in the focus groups
conducted for this proposal was how to
design a label that balanced the
competing interests of completeness and
simplicity. It became clear that different
consumers wanted different amounts of
information and levels of detail about
fuel economy, GHG emissions, and
other emissions, and how vehicles
83 Under EPA regulations, Independent
Commercial Importers (ICIs) are allowed to import
a limited number of older vehicles that can be
certified to the emission standards which were in
effect at the time the vehicle was produced. In some
cases, these standards may be pre-Tier 2 standards.

compare to one another. Many focus
group participants expressed an interest
in most or all of the information that
might be offered, until they saw that the
label they had ‘‘designed’’ would be
cluttered and difficult to read; at this
point, many culled their desired
information down to a few key
elements. Other participants simply
were not interested in much detail. Yet
other participants insisted that they
wanted more detail anyway and would
not find labels with more information
distracting or confusing.84
One approach that emerged to
condense the level of detail was to
combine rating systems: For example, a
rating system that combined fuel
economy and CO2 emissions, or that
combined CO2 and other pollutant
emissions, or that combined all three.
Because they have different sets of units
and different scales, rating systems that
combine different data elements must
employ relative or unit-free scales, such
as the letter grade system, rather than
absolute approaches like the separate
rating scales discussed above. Using the
bar as an example, if CO2 and other
pollutants were combined into a single
bar, a vehicle that falls at one point
between the absolute end points for CO2
emissions may not fall at the same point
between the (different) end points for
other emissions, which would make
combining the ratings challenging at
best, and unhelpful at worst. Similarly,
while a vehicle may fall at roughly the
same point between ‘‘best’’ and ‘‘worst’’
absolute values for both fuel economy
and CO2 emissions, differences in scale
make presenting that visually difficult
and possibly factually incorrect.
Thus, if the agencies wanted to try to
combine rating systems for visual
simplicity and to appeal to consumers
who want labels with less information,
a relative scale—1 to 10, 1 to 5, A+ to
D¥is needed. The agencies tested
combined relative scales for GHG and
other pollutant emissions fairly
extensively in the focus groups, with
mixed results. When environmental
ratings were shown in the context of the
label, the preference was for a
consolidated environmental rating, with
participants expressing minimal interest
in having separate information on
greenhouse gases and other air pollutant
emissions; these participants often
stated that the EPA was in a better
position to assess the relative concerns
regarding the various environmental
factors than were the participants
Because the rating system being proposed for other
pollutants on the FE label is based on the Tier 2
bin structure, we are proposing that vehicles
imported by ICIs that are not subject to the Tier 2
standards will automatically be rated as a ‘‘1’’ (i.e.,
the rating assigned to vehicles with the worst
emissions under the Tier 2 bin structure).

themselves.85 In contrast, however,
when the environmental rating
approaches were shown in isolation,
apart from the context of the entire
label, many participants indicated a
preference for two separate ratings,
arguing that more complete information
holds more value.86
Congress required in EISA that each
new vehicle must be labeled with a
‘‘rating system that would make it easy
for consumers to compare the fuel
economy and greenhouse gases and
other emissions of automobiles at the
point of purchase, including a
designation of automobiles with the
lowest GHG emissions over the useful
life of the vehicles; and the highest fuel
economy* * *’’ Thus, for purposes of
meeting the statute, the question is
whether a rating that combined two or
all three elements could accurately
reflect which vehicle achieves the
lowest GHG and the highest fuel
economy. For purposes of meeting
consumers’ needs in a label, the
question is how to design a label that is
helpful both to the people who want
more information and detail and to the
people who want less information and
detail. Given the EPCA requirements for
fuel economy and annual cost
information, and the EISA requirements
for performance information on fuel
economy, greenhouse gases, and other
emissions, the agencies believe that the
needs for more detail-oriented
consumers will likely be adequately
met.
In the previous section we discussed
an approach to combining fuel economy
and CO2 into one overall rating; in this
section the agencies discuss the
additional option of also combining
‘‘other emissions’’ with either CO2 or
with a combined fuel economy/CO2
rating. EPA and NHTSA recognize that
there is not a strong correlation between
CO2 and other emissions, due to
sophisticated emission control systems,
such as catalytic converters and exhaust
gas recirculation, which target
reductions of specific pollutants but do
not also reduce CO2 emissions. In
addition, the agencies are cognizant of
the very real challenges automakers
must overcome to achieve the required
emissions levels and do not wish to
deprive them of public recognition of
advancements in reducing air pollutants
that could come with a separate rating
system for pollutants. Moreover, a
separate rating would provide

information for purchasers who value
low emission levels and an opportunity
to raise awareness among other
consumers of which vehicles produce
lower emissions. And finally, as
discussed above, the agencies have
determined that a rating for ‘‘other
emissions’’ also meets the EISA
requirement of providing vehicle
performance information for those
emissions. Combining this rating for
‘‘other emissions’’ with ratings for fuel
economy and greenhouse gases would
potentially be at odds with this
requirement. For these reasons, the
agencies propose that the rating for
‘‘other emissions’’ be separate from the
rating(s) for fuel economy and
greenhouse gases.
Nevertheless, while some focus group
participants wanted more information,
most clearly wanted less and suggested
that they would glean little additional
value from a label with separate ratings.
The agencies seek comment on whether
it would be more useful to provide a
single rating that captures all three
elements: fuel economy, greenhouse
gases, and other emissions. As a matter
of technical appropriateness, although
there is not a strong correlation between
emissions of CO2 and emission of other
pollutants, there is some correlation.
The vehicles with the lowest fuel
economy levels and highest CO2
emissions do not typically meet the
cleaner emission bins; conversely, those
with high fuel economy and low CO2
emissions are rarely, if ever, certified to
the higher emission bins.
Including other emissions in the
rating system to form one rating would
simplify for the consumer the overall
energy and environmental impact of
using the vehicle, thus reducing their
need to weigh the relative importance of
the various elements. It also allows the
label to be less cluttered and more
streamlined.
Therefore, it is possible and perhaps
reasonable to combine ‘‘other emissions’’
with the fuel economy/CO2 letter grade
approach. Under this approach, the
rating for fuel economy and greenhouse
gases applicable to a vehicle would be
adjusted upward or downward, based
on the Federal emissions bin (or
California standard) to which the
vehicle is certified. That is, vehicles that
are certified to the cleanest bins would
have their rating increased—for
example, under a letter grade system, a
Bin 2 vehicle otherwise eligible for a B+
would have their rating increased to an
A¥. Table II.A.6–1 illustrates how such
a system could work.

7. Indicating Highest Fuel Economy/
Lowest Greenhouse Vehicles
In addition to ratings indicating
relative emissions performance, EISA
also requires the rating system to
include ‘‘a designation of automobiles
with the lowest greenhouse gas
emissions over the useful life of the
vehicles; and the highest fuel economy.’’
Depending on the rating system(s)
selected, differing approaches may be
needed to achieve this requirement. For
example, if the fuel economy and
greenhouse gas ratings are provided
separately, such as with the absolute
bars shown on labels 1 and 2,
consumers would be able to easily
identify the highest fuel economy and
lowest greenhouse gas emitting vehicles
by looking for those that have the
highest absolute values. If fuel economy
and greenhouse gases are combined into
one rating, such as with the letter grade
system, but are provided separately
from other emissions, again consumers
should be able to easily identify the
highest fuel economy/lowest GHG
vehicles by looking for those that
achieve the best rating category.
However, this will likely encompass
more models than would be designated
‘‘best’’ under an absolute rating system,
which may or may not have been the
intent of EISA. In that instance, the
rating system itself meets the
requirement for designation of lowest
GHG automobiles, defined in that case
as the group of vehicles that achieve the
best rating category.
If, on the other hand, fuel economy
and greenhouse gases are combined
with other emissions into a
comprehensive rating, and no other
information on the label indicates the
highest fuel economy/lowest GHG
vehicles, then the rating system would
need to be adjusted in order to ensure
that EISA requirements were met. The
agencies seek comment on whether

8. SmartWay Logo
EPA and NHTSA additionally seek
comment on utilizing the SmartWay
logo as an indicator of a high level of
overall environmental performance. The
SmartWay logo appears as follows:
The SmartWay logo could be added to
the label as a way of highlighting the top
environmental performers each model
year. This approach is contemplated for
labels 2 and 3.
The trademarked SmartWay
designation was launched in 2005 on
the EPA’s Green Vehicle Guide Web site
(https://www.epa.gov/greenvehicle) to
provide consumers with a quick and
easy way to determine which vehicles
were the cleanest and most fuel efficient
for each model year. It has been
awarded to those vehicle models that
achieve certain thresholds on the
Greenhouse Gas score (which is tied to
the vehicle’s fuel economy and fuel
type) and the Air Pollution score (which
is tied to the Tier 2 bins or California
standards, as applicable). Historically,
the SmartWay thresholds determined by
EPA have been targeted to
approximately the top 20% of vehicle
models each model year, and have been
tightened over time as the fleet has
become cleaner and more fuel efficient.
The SmartWay logo for light duty
vehicles is currently being used on a
voluntary basis by auto manufacturers,
vehicle-search web sites, rental car
companies, banks/credits unions (green
vehicle loan programs), and private
companies (light duty commercial fleets
and employee incentive programs). The
SmartWay logo was included on labels
shown to focus group participants for
this rulemaking. Although participants
did not recognize the logo, most readily
understood that they could use it when
shopping for vehicles to quickly identify
those that were environmentally
friendly, without having to review the
rest of the environmental information
on the label.87
Because focus groups have indicated
that some consumers prefer more
detailed information while others prefer
a simpler presentation, the agencies are
seeking comment on whether to require
or optionally allow the SmartWay logo

on the label for applicable vehicles. This
logo would indicate in a binary fashion,
similar to other eco-labels, whether \ a
vehicle meets certain environmental
and energy use thresholds. Specifically,
the agencies seek comment on whether
including the SmartWay logo would be
helpful to consumers on a label that
already addresses fuel economy, GHGs,
and other emissions in other formats.
9. Annual Fuel Cost
EPCA requires the estimated annual
fuel cost be displayed on the fuel
economy label.88 Prior to 2008, the label
simply displayed the estimated annual
cost with no explanatory information.
EPA’s consumer research in 2006 found
that consumers paid little attention to
this metric, and the reason most
frequently stated was that the
assumptions behind the estimate
(annual miles and fuel price) were
unknown to them.89 As a result, the
2008 label modifications included a
requirement that these assumptions be
placed on the label.90 EPA publishes
annual guidance directing
manufacturers what fuel price to use for
determining annual cost—based on
projections made by the Department of
Energy 91—so that all vehicles in a given
model year use the same assumptions.
The estimated annual fuel cost can
therefore be used to compare across
vehicles of the same model year. As an
example, the estimated annual fuel cost
to be used for labels on model year 2008
gasoline-fueled vehicles is $2.80.
Despite the addition to the label of the
assumptions behind the annual fuel cost
starting in 2008, the early focus groups
conducted in 2010 showed that many
participants still did not pay much
attention to the estimated annual fuel
cost metric. Participants often stated
that this was because fuel prices
fluctuate and, therefore, they did not
think that the fuel price assumption
stated on the label reflected what they
were actually paying. Less frequently,
participants additionally said that the
fact that they did not drive 15,000 miles
a year made the estimated annual cost
not meaningful to them. Participants
remained skeptical of the use of
estimated annual fuel cost even when
asked to consider whether it could be a
useful comparative metric across other
U.S.C. 32908(b)(1)(B).

Administration publishes gasoline and diesel fuel

vehicles of the same model year. In
retrospect, it is possible that providing
this information on the label about the
assumptions behind the annual fuel cost
number resolved one issue and caused
others, in that now there are two more
numbers for the consumer to process
and question. There is also the
possibility that consumers are not aware
that the two assumptions are used
universally across all vehicles, which
would call into question the usefulness
of the metric as a comparative tool at the
point of purchase (for example, if they
believe that the manufacturers
individually determine the inputs to the
estimated annual fuel cost). However,
participants in the Phase 3 focus groups
leading up to this NPRM consistently
employed the annual fuel cost
information (along with MPG) when
asked to compare the fuel efficiency of
advanced technology vehicles like
PHEVs and EVs with conventional
vehicles, with their more complicated
set of energy metrics.92
Recognizing the EPCA statutory
requirement to continue to display the
estimated annual fuel cost, EPA requests
comment on how to improve
consumers’ understanding of the
estimated annual fuel cost, whether it is
a useful comparative tool across
technologies, and if so, how to best
communicate on the label that it is a
valid comparative tool. EPA also
requests comment on whether there
might be an additional way to display
fuel cost information—or a better way of
displaying the required information—
that might be more useful or might have
a greater impact on consumers. In the
2010 focus groups, some groups were
presented with a number of different
ways of displaying fuel costs on the
label, ranging in magnitude from dollars
per mile to dollars per five years.93 A
fairly clear preference emerged for
dollars per year, with dollars per month
a frequent second choice.94 EPA is thus
proposing labels that continue to
prominently display the estimated
annual fuel cost and the associated
assumptions. EPA is requesting
comment on whether the label should
include the estimated monthly fuel cost,
or other alternative cost information.
Commenters should bear in mind the
statutory requirement that estimated
annual fuel cost be on the label; thus

any other cost would have to be an
additional piece of information.
10. Relative Fuel Savings or Cost
The expert panel recommended
another approach to presenting fuel cost
information—to focus on the savings
attainable by purchasing a more fuel
efficient vehicle. These panelists felt
strongly that savings is a much more
powerful message than cost, which
tends to be discounted, as just
discussed. Although savings
calculations would necessarily also rely
on assumptions, they suggested that the
value of savings to the consumer is
significant enough to overcome these
drawbacks, at least for a substantial
portion of the population. NHTSA and
EPA therefore propose including a fiveyear savings value on Label 1. No such
value is proposed for Labels 2 or 3,
although the agencies could also require
savings information on these labels, if
one of them were finalized.
The agencies explored a number of
methods for calculating savings. The
most promising approach seems to be
savings compared to the projected
median vehicle for that model year, and
the agencies propose this method. Thus,
some vehicles would show a savings,
while others would show consumers
paying more for fuel over five years
compared to a reference vehicle; these
values would increase in magnitude the
further the vehicle is in terms of fuel
consumption from the reference value.
This approach appropriately reflects
that fuel cost savings become larger the
more a vehicle improves their fuel
economy, and conversely that vehicles
cost more to fuel when fuel efficiency is
decreased when compared to the
reference, median, vehicle.
As with the fuel economy and
greenhouse gas rating system and
comparable class information, the EPA
would provide annual guidance
indicating the value to be used as the
reference against which the fuel cost
savings would be measured. The
reference five-year fuel cost would be
calculated by applying the gasoline fuel
price to the average miles driven over
the first five years of the reference
vehicle’s life, assuming a particular fuel
economy for the reference vehicle; these
values would be provided in the annual
guidance. We propose that the fuel
economy value for the reference vehicle
be based on the projected fuel economy
value of the median vehicle model type
for sale the previous model year, not
sales-weighted, and adjusted based on
projections regarding the upcoming
model year. This value is expected to
change slightly from one year to the
next as the fleet becomes more fuel
VerDate Mar<15>2010
18:48 Sep 22, 2010
Jkt 220001
efficient in response to regulations and
market forces. The guidance would also
include the fuel prices to be used to
calculate fuel cost savings for the
particular vehicle, based on its
applicable fuel type. Finally, we
propose to round the fuel cost savings
values used on the label to the nearest
one hundred dollars to avoid implying
more precision than is warranted, as
well as for ease of recall.
As previously stated, vehicles with a
higher fuel economy than the median
vehicle would be designated as saving
the consumer a certain number of
dollars over a five year period. For those
vehicles with fuel economy lower than
the median vehicle, the label would
state that the consumer would spend a
certain number of dollars more over a
five year period. Vehicles that are
within fifty dollars of the reference
vehicle fuel cost could be designated as
saving zero dollars. Alternatively, text
could indicate that this vehicle is
comparable to the average vehicle.
Although the agencies recognize that
‘‘median’’ is a more accurate term than
‘‘average,’’ we propose the use of the
term ‘average’’ as being more readily
understandable.
Other methods considered include
savings compared to the average vehicle
one grade lower, and fuel cost savings
compared to vehicles 10 MPG lower.
These approaches had certain positive
aspects, particularly in that they
demonstrated the value of incremental
improvements in vehicle choice. In the
main, however, they provided values
that seemed to be difficult to interpret
and could perhaps cause perverse
effects. For example, a vehicle at the
high end of their grade or rating would
have a higher savings value than a
vehicle at the low end of their grade or
rating. This might be valuable for those
who are considering vehicles within the
same grade. However, for those
shoppers who glanced at the number
quickly, they might erroneously
conclude that, for instance, a vehicle at
the low end of the B- grade would save
less on fuel costs than a vehicle at the
high end of the D+ grade. The agencies
seek comment on this and alternative
approaches, as opposed to the proposed
approach of displaying a vehicle’s fuel
cost savings relative to the median
vehicle in the fleet. The agencies are
also seeking comment on whether there
is a potential for consumer confusion
caused by two different cost values
displayed on Label 1 with regard to the
estimated annual fuel cost of operating
the vehicle and the 5 year fuel cost
savings number compared to the average
vehicle. We are interested in receiving
comments on how consumers may
PO 00000
Frm 00024
Fmt 4701
Sfmt 4702
perceive these values as interacting with
each other and we intend to explore this
issue further prior to finalizing this
proposal, including exploring research
conducted in executive branch agencies.
11. Range of Fuel Economy of
Comparable Vehicles
EPCA requires that the label contain
‘‘the range of fuel economy of
comparable automobiles of all
manufacturers,’’ a requirement that the
label addressed somewhat awkwardly
for many years.95 As a result of EPA’s
2006 labeling rule, the labels now use a
graphical element to show the
performance of the labeled vehicle
relative to the best and worst within that
vehicle class.96 In the 2010 focus
groups, it became clear that this
information, though more prominently
displayed on today’s fuel economy label
than in previous iterations of the label,
continued to be under-utilized by
consumers as a tool to assist them in
making vehicle purchase decisions.
EPA is now proposing two possible
ways of meeting this statutory
requirement. Given the likelihood of
more information on the label, a graphic
as used on the current label that repeats
the combined fuel economy number
may overly complicate the new label.
Thus one option being proposed is
simply a text statement that would read
‘‘Combined fuel economy for [insert
vehicle class] ranges from XX to XX.’’
This approach is used on Labels 1 and
3. The other option EPA is proposing is
essentially an updated version of the
current graphical representation, which
combines the fuel economy rating across
all vehicles with the within-class
information into one graphical element,
as shown in Section III as part of Label
2.
The agencies believe that one of these
approaches could be used to satisfy the
statutory requirements in 49 U.S.C.
32908(b)(1)(C) (‘‘the range of fuel
economy of comparable automobiles’’).
As an alternative, EPA seeks comment
on whether the requirement to indicate
fuel economy of comparable vehicles is
met by the overall fuel economy rating
required by 49 U.S.C. 32908(g)(1)(A)(ii)
(‘‘a rating system that would make it
easy to compare the fuel economy * * *
of automobiles’’), given that consumers
tend to consider vehicles from several
classes during their purchase process.
12. Other Label Text
EPA is proposing some minor changes
and an addition to the text on the label
95 49
U.S.C. 32908(b)(1)(C).
CFR 600.307–08. A discussion of the
comparable class categories and a proposed change
to those categories can be found in section VI.B.

23SEP3
mstockstill on DSKH9S0YB1PROD with PROPOSALS3
Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
not previously discussed, and seeks
comment on each of these text changes.
First, each of the proposed labels has
information that indicates the fuel on
which the vehicle operates. The
agencies believe it will become
increasingly important, as different
technologies emerge, to display clearly
the kind of vehicle a consumer is
viewing. For dual fuel vehicles (e.g.,
current gasoline/ethanol vehicles), EPA
is required by statute to identify the
vehicle as a dual fuel vehicle and to
identify the fuels that the vehicle
operates on.97 In the case of current
flexible-fuel vehicles, for example, this
text would read ‘‘Dual Fuel: GasolineEthanol (E85),’’ and for plug-in hybrid
vehicles arriving soon on the market
this text would read ‘‘Dual Fuel:
Gasoline-Electricity.’’ In addition, we are
proposing the use of various icons on
the label to distinguish between
different technologies and between
different operating modes. These icons
include stylized electric plugs, fuel
pumps, and fuel dispensing nozzles.
Second, because of the expanded
information on the label and DOT
requirements under EISA, EPA is
proposing to change the label heading
from the current text (‘‘EPA Fuel
Economy Estimates’’) to ‘‘EPA/DOT Fuel
Economy & Environmental
Comparisons.’’ We also propose adding
the DOT logo to the label, to provide
appropriate recognition of DOT’s role
mandated by EISA.
Third, EPA is proposing to change the
Fuel Economy Guide statement found
on the label to reflect the expanding
features that comprise https://
www.fueleconomy.gov, with the hope
that this Web site will become the first
Internet stop for a vehicle’s fuel
economy and environmental
information. The proposed text would
read: ‘‘Visit https://www.fueleconomy.gov
to calculate estimates personalized for
your driving, and to download the Fuel
economy Guide (also available at
dealers).’’
EPCA requires EPA and the
Department of Energy (DOE) to prepare
and distribute to dealers a fuel economy
booklet, commonly known as the annual
‘‘Fuel Economy Guide,’’ containing
information that is ‘‘simple and readily
understandable.’’ 98 EPCA requires that
the guide include fuel economy and
estimated annual fuel costs of operating
automobiles manufactured in each
model year, as well as some additional
information for dual fueled automobiles
(such as the fuel economy and driving
range on both fuels). Further, EPCA

U.S.C. 32908(c)(1)(A).
VerDate Mar<15>2010
18:48 Sep 22, 2010
requires that a statement appear on the
fuel economy label that this booklet is
available from dealers.99 Starting in the
2008 model year, the statement on the
label was broadened to include a
reference to https://
www.fueleconomy.gov as another source
for the Fuel Economy Guide; this Web
site is based on the EPA fuel economy
information and jointly run by EPA and
DOE. Thus the current text now reads:
‘‘See the FREE Fuel Economy Guide at
dealers or https://
www.fueleconomy.gov.’’
Both the U.S. Department of Energy’s
Office of Energy Efficiency and
Renewable Energy and the EPA
currently maintain https://
www.fueleconomy.gov. The site helps
fulfill DOE and EPA’s responsibility
under EPCA of 1992 to provide accurate
MPG information to consumers. The site
provides fuel economy estimates, energy
and environmental impact ratings, fuelsaving tips, as well as a downloadable
version of the fuel economy guide and
other useful information. Since its
inception in 1999 this Web site has been
used by millions of consumers, and the
latest data from 2008 indicates that
more that 30 million user sessions
occurred in that year.
Because of the extensive amount of
information and user features available
on the Web site beyond simply
providing electronic access to the Fuel
Economy Guide, the agencies wish to
direct consumers to this Web site when
they are researching their vehicle
purchases. For example, the Web site
allows a user to personalize their fuel
economy information by inputting their
specific driving habits and fuel prices.
This ability will be even more important
for understanding the impacts of driving
distance and battery charging habits on
the fuel consumption of vehicles like
plug-in hybrid electric vehicles, and
EPA expects to work with DOE to
develop a Web-based system to allow
users to customize the fuel economy
estimates for these advanced technology
vehicles. Further, information that some
consumers may want but that is not
available on the label is likely to be
available on the Web site. For example,
in the 2010 focus groups some
participants expressed an interest in
knowing the cost to fill the tank, or the
volume of the fuel tank, or how many
miles could be driven on a tank. The
Web site provides all this information,
and information such as the miles per
tank can be personalized to reflect a
person’s relative amount of city and
highway driving. Finally, the Web site

also has developed a version tailored to
mobile devices.
During the expert panel, EPA
provided the panelists with a copy of
the current Fuel Economy Guide. The
panelists all expressed concerns that the
public probably didn’t know it was
available, didn’t access it at the dealer
showrooms if they did know it was
available, and would not respond well
to it in its current format. They
recommended a simple one-sheet
‘‘guide’’ that dealers would distribute in
the form of a checklist, that would allow
EPA to deliver the top ten points on fuel
economy that could not (and should
not) be included on the label. It also
would ensure that even if individuals
did not utilize the Web site, they would
receive this information. It was also
suggested that if possible, distribution of
this document be mandatory.
EPA requests comments on the
usefulness of the Fuel Economy Guide
in its current form and also requests
comments on whether EPA and DOE
should develop a different approach in
the future to the Fuel Economy Guide—
including the idea of transforming the
guide into a consumer friendly
‘‘checklist’’ guide. While EPA recognizes
that it does not have the authority to
mandate distribution of this guide by
dealers we also request comments on
how we could better encourage and
work with dealers to more prominently
display and distribute the fuel economy
guide in the future.
The expert panel also strongly
recommended that the new fuel
economy label prominently display an
easy to remember URL. Panelists
suggested that not only should such a
URL be easy to remember, it should also
provide a consistent platform for
educational messages that would be
highly visible for consumers and serve
as a portal for web users to engage each
other on fuel economy issues, including
exchanging helpful tips and tools.
Panelists indicated that this type of URL
and message platform is of critical
importance in today’s marketplace and
that EPA should make better use of the
label to engage the public in this
manner. Finally, the panelists
recommended this new URL not be a
‘.gov’ Web site, which they suggested is
generally perceived as static and
uninviting by consumers that are
increasingly reliant on highly
interactive social media networks and
tools. Label 1 series found in Section III
currently displays how this URL
concept might be incorporated in Label
1. We note that President Obama has an
initiative on transparency and open
E:\FR\FM\23SEP3.SGM
23SEP3
58102
Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
government,100 and as part of this
initiative, the Executive Branch has
already made some significant
improvements to its Web sites.
The agencies request comment on the
new URL concept displayed on Label 1,
along with the underlying approach
recommended by the expert panel: That
the agencies create and display a
prominent URL on the label that will
provide both a visible consumer
message and an easy to remember web
portal or gateway to a more interactive
consumer Web site. As envisioned, this
Web site would introduce the new label
approach, laying out what is new and
unique to this label. It would explain
what the agencies are trying to
accomplish with the new design, and
detail the concept of the grading system
and underlying scoring method. It
would include applications that
consumers can use to personalize their
vehicle buying decisions, based on their
own driving habits and needs. It would
also provide information that is not
available on the label, such as the
upstream emissions associated with
each vehicle choice. It would also link
to the detailed vehicle information and
consumer discussion pages on
fueleconomy.gov, capitalizing on the
existing government Web site and
further maximizing its consumer
friendliness and usability.
Finally, for conventional vehicles,
EPA is not proposing any changes to the
statement that currently reads ‘‘Your
actual mileage will vary depending on
how you drive and maintain your
vehicle.’’ However, because some
advanced technology vehicles are
especially susceptible to certain
conditions, such as cold weather, EPA
is considering the addition of some
specific qualifications to this statement
for some vehicle technologies, and seeks
comment on what qualifications might
be most helpful.

13. Gas Guzzler Tax Information
EPCA requires that ‘‘Gas Guzzler’’ tax
information be included on the fuel
economy label.101 These taxes are
required under the Internal Revenue
Code 26 U.S.C. 4064(c)(1). This part of
the Internal Revenue Code contains the
provisions governing the administration
of the Gas Guzzler Tax, and specifically
contains the table of applicable taxes

and defines which vehicles are subject
to the taxes. The IRS code specifies that
the fuel economy to be used to assess
the amount of tax will be the combined
city and highway fuel economy as
determined by using the procedures in
place in 1975, or procedures that give
comparable results (similar to EPCA’s
requirements for determining CAFE for
passenger automobiles). These
provisions have been codified in 40 CFR
600.513–08. This proposed rule would
not impact these provisions.
The current labeling requirements for
the Gas Guzzler Tax require that an
affected vehicle have the following
statement on the label (the regulations
provide different ways of displaying this
depending on the label; for example, an
alternative fuel vehicle label has some
additional information that limits space,
thus the template for labeling such a
vehicle accounts for this). In the limited
situations in which this labeling
requirement applies, EPA expects to
provide label templates including this
information that are consistent with the
label design that is ultimately selected.
For example, for Label 1 presented in
Section III, one potential option is to
place the gas guzzler information in the
position for fuel cost savings. EPA seeks
comment on this approach.
B. Advanced Technology Vehicle Labels
1. Introduction
In the past, EPA has not devoted
much effort to fuel economy label issues
for advanced technology vehicles. There
is a simple reason for this—if EPA
defines a conventional vehicle to be that
which derives all of its propulsive
energy from a petroleum fuel (or a
liquid fuel blend dominated by
petroleum) stored on-board the vehicle,
then conventional vehicles have
represented well over 99% of all
vehicles sold since the advent of fuel
economy labels in the 1970s. EPA made
the judgment that the very small
number of consumers who might have
considered the purchase of an electric or
natural gas or other type of advanced
technology vehicle over the last 35 years
did not justify a major investment of
government resources to address the
more complex issues associated with
advanced technology labels. Rather,
EPA addressed the occasional need for
an advanced technology vehicle label on
a case-by-case basis.
But, this situation is changing and as
the market evolves, this approach is no
longer sufficient. For the first time since
labels have been in use (in fact for the
first time since the early days of the
automotive industry), it appears
increasingly likely that the future
PO 00000
Frm 00026
Fmt 4701
Sfmt 4702
automotive marketplace will offer a
much more diverse set of technological
choices to consumers. EPA and NHTSA
believe that now is the time to begin to
design labels that are more appropriate
for advanced technology vehicles that
we expect to be commercialized in the
next few years. For purposes of this
rulemaking, the agencies intend to focus
on two advanced technologies:
• Electric vehicles (EVs) are vehicles
that are powered exclusively by
batteries (charged with electricity from
the grid) and electric motors, and which
do not have a conventional internal
combustion engine or any other
powertrain. Several automakers sold
EVs in the early and mid-1990s,102 but
the only EV on the U.S. market today is
the luxury Tesla Roadster with annual
sales of a few hundred vehicles. The
first more mainstream-priced EV offered
for sale in the U.S. is the Nissan Leaf,
for which orders are now being taken
and first deliveries are projected for late
this year in selected markets.103 In

• Plug-in hybrid electric vehicles
(PHEVs) can be powered in as many as
three different ways: (1) Like an EV,
exclusively by batteries and electric
motors, (2) like a conventional hybrid
vehicle, when the vehicle gets all of its
propulsive energy from a conventional
internal combustion engine/
transmission (usually fueled with
gasoline), though the battery still assists
with regenerative braking and engine
buffering, and (3) a combination of both
conventional hybrid and electric
operation. PHEVs entail a family of
different engineering approaches, and
will continue to evolve as the
technology matures. One distinct type of
PHEV is called an extended range
electric vehicle (EREV). An EREV PHEV
has a very distinct operational profile:
As long as the battery is above its
minimal charge level, the vehicle is
operated exclusively on the electric
powertrain, and then when the battery
is at its minimal charge, it operates like
a conventional hybrid getting all of its
power from gasoline or other liquid fuel.
In a way, an EREV PHEV can be

considered to be a combination of an EV
and a conventional hybrid, with an
emphasis on operating like an EV as
much as possible. There have been no
commercial EREV PHEVs sold in the
U.S. to date but the first commercial
offering is likely to be the Chevrolet
Volt, which is scheduled to be
introduced in late 2010.105 A second
type of PHEV is called a ‘‘blended’’
PHEV. As long as the battery is charged,
it will operate on a combination of grid
electricity and gasoline (while a blended
PHEV might not have any ‘‘guaranteed’’
all-electric range, it is possible that
some blended PHEV designs may have
some all-electric range under certain
driving conditions), then when the
battery is at its minimal charge, the
vehicle gets all of its propulsive energy
from the gasoline fuel and engine
(though the battery still assists with
regenerative braking and engine
buffering, as with a conventional
hybrid). In this respect, a blended PHEV
can be viewed as a combination of a
‘‘grid-enhanced’’ hybrid and a
conventional hybrid, but without the
emphasis on using only electricity for
shorter trips as with the EREV PHEV. To
the degree that a blended PHEV does
have some practical all-electric range,
the boundary between a blended PHEV
and an EREV PHEV begins to blur.
There have been no original equipment
blended PHEV offerings in the U.S. to
date, but many automakers are
developing prototypes and some
aftermarket conversions are available.
The first commercial U.S. blended
PHEV may be a Toyota Prius, likely
offered as a 2012 model.106
Other advanced technology vehicles
will also likely be on the market in the
near future—for example, Honda
continues to sell a dedicated
compressed natural gas Civic in selected
states and several manufacturers plan to
sell fuel cell vehicles (FCVs) in the
future.107 In any case, the issues
associated with and the decisions that
we make about labels for EVs and
PHEVs will go a long way toward
preparing us to address labels from
other advanced technologies in the

future. EPA and NHTSA seek comments
on whether there are other advanced
technologies that have the potential to
achieve mainstream interest in the near
future and for which the agencies
should develop labels in a future
rulemaking.
PHEVs and EVs represent a
fundamental departure from the
powertrain and fueling infrastructure
that has exclusively dominated the U.S.
market for the last century—a single
powertrain (an internal combustion
engine with a mechanical transmission)
and a single fuel (gasoline) available at
public service stations. While PHEVs
retain this option, they also offer the
consumer the option to charge the onboard battery from the electric grid at
home and to propel the vehicle
exclusively or partially by the battery
and electric motor. An EV must be
operated this way. These fundamentally
different powertrains and refueling
approaches raise many challenging
issues from a consumer information
standpoint that may affect how the
agencies decide to require these vehicles
to be labeled.
• These technologies are still
evolving. EPA has been able to test only
a small number of these advanced
technology vehicles, and it is unclear
whether the vehicles that we have tested
are a good reflection of the technologies
that will ultimately be offered in the
market.
• Gasoline and electricity are very
different automotive fuels. Gasoline is a
liquid fuel with a high energy density
that is stored on-board the vehicle in a
relatively simple and lightweight tank
that can be filled in a few minutes,
while electricity is generated by
chemical reactions inside a much lower
energy density (and therefore heavier)
battery pack and which can take many
hours to recharge. Gasoline is produced
very efficiently from crude oil, but is a
less efficient vehicle fuel, while
electricity is less efficient to produce
from a wide variety of resources (such
as coal, nuclear, natural gas,
hydropower, and wind), but is a more
efficient vehicle fuel. Approximately
80% of the ‘‘life-cycle’’ greenhouse gas
emissions from a gasoline vehicle are
emitted directly from the vehicle
tailpipe, while all of the life-cycle
greenhouse gas emissions associated
with an electric vehicle are ‘‘upstream’’
of the vehicle. As just one simple
example, miles per gallon, the core
metric that has been used on gasoline
labels for the last 35 years, is a much
more complicated metric for a fuel like
electricity which is not measured in
gallons.

• Some advanced technologies can
operate on more than one fuel, either
simultaneously (e.g., the use of gasoline
and electricity in the charge depleting
mode of a blended PHEV) or at different
times (e.g., an EREV PHEV uses
electricity in charge depleting mode,
then gasoline in hybrid mode). By itself,
this suggests that a consumer label for
a vehicle that operates on two fuels
might have to have approximately twice
as much information as a label for a
vehicle that operates on a single fuel.
• Consumer behavior can have a
much larger impact on the operation of
an advanced technology vehicle,
relative to that of a conventional
vehicle. Whether the owner of a PHEV
charges the battery every night and how
many miles per day they drive—neither
of which affects average energy
consumption for a conventional
vehicle—can have a dramatic impact on
energy and environmental performance.
Again using the standard miles per
gallon of gasoline metric as an example,
one EREV PHEV design may vary from
35 or 40 MPG on the low end (when the
battery is empty and the vehicle is in
hybrid mode) to essentially ‘‘infinite’’
MPG-gasoline if the vehicle is operated
only off the battery pack. This fuel
economy variability is much greater
than with conventional vehicles, where
MPG values for most individual
vehicles are typically within 15–20% of
the average value.
• Consumers have no practical
experience with these new technologies,
or in some cases might not even
understand the basics of how the
technologies work. While EPA has
sponsored focus groups to gauge what
consumers want on advanced
technology labels, there can be little
question that consumers are in a
stronger position to provide meaningful
input on conventional labels, with
which they have decades of experience,
than on advanced technology labels,
where they may not now know what
they will want and need to know in the
future to make informed purchase
decisions.
All of these factors suggest that there
is the likelihood of significant consumer
confusion when multiple advanced
technology vehicles begin to compete in
the marketplace. We have no illusions
that our advanced technology labels will
completely resolve this consumer
confusion, but we do hope they will
help to reduce the confusion. We are
certain that advanced technology labels
will be more complicated than
conventional vehicle labels. Just as EPA
has repeatedly refined the much simpler
conventional vehicle labels over time,
the agencies expect to do so with
E:\FR\FM\23SEP3.SGM

advanced technology vehicle labels as
well. Accordingly, while EPA and
NHTSA are co-proposing two specific
labels for EVs and PHEVs, the agencies
also seek public comment on as many
of the key issues as possible.
While this section will discuss EVs
and EREV PHEVs as well, in many cases
blended PHEVs will be the illustrative
technology because they often raise the
most challenging issues due to the fact
that two different fuels can be used
simultaneously.
2. EPA Statutory Requirements
mstockstill on DSKH9S0YB1PROD with PROPOSALS3
a. Electric Vehicles (EVs)
Electricity is an alternative fuel under
the statute and vehicles fueled only by
alternative fuel are ‘‘dedicated
automobiles.’’ 108
b. Plug-In Hybrid Electric Vehicles
(PHEVs)
Some PHEVs are dual fueled
automobiles under 49 U.S.C.
32901(a)(9). They are capable of
operating on a mixture of electricity and
gasoline, provide superior energy
efficiency when operating on electricity
compared to operating on gasoline, and
provide superior efficiency when
operating on a mixture of electricity and
gasoline as when operating on
gasoline.109 These vehicles also meet
the requirement that a dual fueled
automobile must meet the minimum
driving range under 49 U.S.C.
32901(c).110 DOT has set the minimum
driving range for electric vehicles at 7.5
miles on its nominal storage capacity of
electricity when operated on the EPA
urban test cycle and 10.2 miles on its
nominal storage capacity of electricity
when operated on the EPA highway test
cycle.111
The statute contains particular
requirements for dual fueled automobile
labels. Section 32908(b)(3) requires that
each label (A) indicate the fuel economy
of the automobile when operated on
gasoline or diesel fuel, (B) clearly
identify the automobile as a dual fueled
automobile, (C) clearly identify the fuels
on which the automobile may be
operated; and (D) contain a statement
that additional information required by
the statute is in the fuel economy
booklet. The additional information
required in the booklet for dual fuel
automobiles is described in 32908(c)(2)
and states that the label will include the

gasoline as compared to when operated
on alternative fuel and the driving range
when operated on gasoline as compared
to when operated on alternative fuel. It
should also include information on the
miles per gallon achieved when
operated on alternative fuel and a
statement explaining how these
estimates may change when the
automobile is operated on mixtures of
alternative fuel and gasoline.
For simplicity and consistency, the
agencies plan for all PHEV fuel
economy labels to contain the
information required for dual fueled
vehicles under the statute, even though
only some PHEVs are dual fuel
automobiles. We seek comment on this
approach.
The fuel economy required on the
label means the average number of miles
traveled by an automobile for each
gallon of gasoline (or equivalent amount
of other fuel) used.112 Therefore, in
order to meet the statutory requirement
that fuel economy be displayed on the
label, the electricity use for EVs and
PHEVs on the fuel economy label is
converted to gallons of gasoline
equivalent.
EPA recognizes that the statutory
requirements in the Energy Policy and
Conservation Act of 1975 were adopted
long before advanced technologies like
EREV PHEVs and blended PHEVs were
even conceived. While EPA must meet
the statutory requirements, the agencies
are concerned that requiring electricity
to be conveyed in MPG equivalent
values might actually make an advanced
technology vehicle label less useful to
consumers. The agencies seek public
comment on this question as explained
in more detail below.
3. Principles Underlying the CoProposed Advanced Technology Vehicle
Labels
The agencies have found it helpful to
identify a few basic principles to guide
our thinking about and development of
advanced technology vehicle labels.
• The advanced technology vehicle
labels should provide objective
information that helps consumers make
good decisions for both themselves and
the environment. The market research
undertaken for this rulemaking found
that the current fuel economy label is a
trusted source of information regarding
the fuel economy of today’s
conventional gasoline vehicles and the
agencies seek to build on this
foundation by ensuring that consumers
receive objective, useful and essential
information that helps inform their
advanced technology vehicle

purchasing decisions.113 The agencies
recognize that many of the most
important drivers for the public and
private interest in advanced vehicle
technologies are in fact related to energy
and environmental considerations.
• The advanced technology vehicle
labels should aim for the simplest way
to provide fairly complex information.
As discussed above in the introduction
to this section and with specific
examples later in this section, the
agencies are aware that advanced
technology vehicle labels will
inherently be more complex than
conventional vehicle labels. We strive to
strike a balance between providing
sufficient information to be helpful and
credible (too simple runs the risk of
misinformation with such complex
technologies), without trying to ‘‘do
everything’’ on the label (which could be
a source of confusion for many
consumers). We believe that automakers
and respected third-party organizations
(and possibly the federal government
via fueleconomy.gov or other Web sites)
will develop sophisticated on-line (and
possibly on-vehicle) calculators that
will allow consumers to customize
energy, environmental, and cost
information for their unique driving and
battery re-charging habits. We believe
that labels should be aimed at the
consumer who wants a quick overview
of energy, environmental, and cost
performance, and that those consumers
who want detailed, customized
information will look to other sources.
• The advanced technology vehicle
labels must be as equitable as possible
across different technologies, both
advanced and conventional. For
example, the agencies want to avoid
picking a label design or label metric
that inherently favors a certain
advanced technology beyond the energy
and environmental merits of the
individual vehicles. There could be
considerable consumer confusion when
multiple advanced technology vehicles
reach the market, each with their own
marketing strategy, and labels are one
way to minimize consumer confusion.
We specifically solicit comments from
automakers on whether we have
achieved this goal of equity with our
proposed label designs.
• Finally, while labels should provide
one or more metrics to compare across
vehicle technologies, both advanced and
conventional, the advanced technology
vehicle labels do not have to have the
same precise design as conventional
vehicle labels. Given that many of the

a. Upstream Emissions
This section discusses how the
agencies plan to address the issue of
greenhouse gas emissions associated
with the use of motor vehicles, in the
context of a program specifically
designed to provide consumers with
information that will be useful when
purchasing a vehicle. The agencies’
approach takes into account (1) the
statutory language, (2) the fact that the
law requires a great deal of information
to be presented on the label, (3) the
limited amount of information that can
be provided on a label, (4) the
importance of simplicity, clarity,
accuracy, and intelligibility on the label,
and (5) the ability to provide the public
with additional and comprehensive
information in a consumer-friendly
format on a Web site.114 This discussion
focuses on, but is not limited to, the
advanced technology vehicles that use
electricity from the grid to power
vehicles, such as the electric vehicles
and plug-in hybrids that are expected to
enter the market in larger numbers in
the coming years; the discussion also
refers to the use of renewable fuels in
gasoline-powered vehicles.
For reasons outlined below, our
proposed approach would limit the
label to tailpipe-only emissions while
providing much fuller information on a
Web site. But we also identify, and seek
comments on, alternative approaches,
designed to accommodate the relevant
variables.
The agencies believe that the
proposed approach follows from a
reasonable interpretation of the Energy
Policy and Conservation Act (EPCA), as
amended by the Energy Independence
and Security Act (EISA) of 2007. The
statute states that NHTSA must require
vehicles to be labeled with information
‘‘reflecting an automobile’s performance
* * * [with respect to] greenhouse gas
* * * emissions * * * of the
automobile.’’ 115 This information is to
be based on criteria developed by EPA.
NHTSA believes that a reasonable
interpretation of this provision is that
only GHG emissions directly from the
vehicle itself are required for the label.
On that interpretation, the information
on performance and the rating of the
vehicles would both be based on the
emissions of the vehicle itself. This
interpretation is also consistent with the
history of the EPA labeling program and
its focus on the vehicle itself. NHTSA
believes that it would also be reasonable
to interpret the statutory language such
that the required label information on
GHG emissions would include
additional information on the upstream
GHG emissions associated with
electricity or other fuels used by the
vehicle. This additional information
could provide a broader context for
reflecting the automobile’s performance
with respect to GHG emissions.
The agencies recognize that ‘‘lifecycle’’
GHG emissions are associated with the
production and distribution of all
automotive fuels used by motor
vehicles. Lifecycle GHG emissions are
associated with gasoline, diesel, and
other fuels such as natural gas,
electricity, and renewable biofuels. The
agencies also recognize that while
tailpipe-only emissions provide
important information, a significant
number of consumers may want, or
benefit from, access to information on
the total upstream GHG emissions
associated with the operation of their
vehicles. For example, electric vehicles
do not have any tailpipe emissions since
their motors do not burn fuel, but
producing the electricity used to power
such vehicles most likely emits
greenhouse gases. Consumers might
seek, or benefit from, a label that allows
for simple and accurate comparisons
across vehicles on the total upstream
GHG emissions, in addition to tailpipe
emissions. However, the agencies
emphasize that developing the relevant
information, and providing it to
consumers in a manner that is accurate
and meaningful, raises a number of

32908(g)(1)(A)(ii) also refers to GHG ‘‘emissions of
automobiles,’’ and further requires a designation of
automobiles ‘‘with the lowest greenhouse gas
emissions over the useful life of the vehicles.’’
label content issues associated with
advanced vehicle technologies are much
more complex than for conventional
vehicles, it would probably be
impossible for the labels to look the
same. On the other hand, we do want
the ‘‘look and feel’’ of the advanced
technology and conventional vehicle
labels to be as consistent as possible.
EPA and NHTSA seek public
comment on the appropriateness of each
of these principles, and whether there
are additional principles that we should
consider.

challenging issues, particularly in the
context of the label.
A full lifecycle evaluation would
include an evaluation of a
comprehensive set of GHG and energy
impacts associated with both the vehicle
(extraction and processing of materials,
energy used in assembly, distribution,
use, and disposal, etc.), and the fuel
(feedstock extraction, feedstock
transport, fuel processing, fuel
transport, etc.). In practice, however,
offering even the more limited
accounting for GHG emissions from
production and distribution of the fuel,
including electricity, presents complex
challenges. EPA currently does not
measure fuel combustion/electricity
generation GHG emissions in its vehicle
testing. The agencies recognize that
modeling can be performed to assist in
estimating these emissions. But in
developing upstream GHG emissions
values, modeling would need to be done
carefully to avoid inaccuracy and
consumer confusion, especially in light
of variations across time and across
regions. For example, GHG emissions
from electricity generation will vary
significantly in the future, based on the
different fuels used at generating
stations—perhaps by as much as an
order of magnitude between coal and
non-fossil feedstocks.
It is true that the EPA has undertaken
extensive lifecycle modeling of biofuels
for the Renewable Fuel Standard
rulemaking in response to the
requirements of the Energy
Independence and Security Act. But
that assessment was done in the context
of the particular mix of biofuels
required nationally in 2022 by the Act,
with a series of assumptions and
estimates that may not be accurate
today.
One overriding issue is whether the
agencies could reasonably provide a
single, national value for GHG
emissions from electricity generation or
could provide instead different values
customized for various regions of the
country.116 There are data sources upon
which a single national number could
be derived. For individual owners,
however, a single national value would
generally not be accurate, and the
individual would need access to
additional information, such as regional
values, to evaluate the impact of a
specific vehicle.117 In addition, the

Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
agencies would have to decide (1)
whether to use average or marginal (i.e.,
reflecting the fact that increased vehicle
demand might change the overall mix of
electricity sources) GHG emissions
factors, and (2) if the marginal approach
is used, whether to assume all nighttime
charging or a mix of daytime and
nighttime charging. Another major
consideration is whether to base
electricity generation GHG emissions
values on today’s electricity markets or
on projected changes in electricity
markets that might occur by 2020 or
some other year (note that vehicles
produced in the next few years will
remain in the fleet for 15 or 20 years or
more).
Some states have already passed
legislation that could require major
changes in how electricity is produced
in those states in the future, and
Congress has considered landmark
legislation as well. It is clear that the
question of how electricity will be
produced in the future is very fluid. As
a result of the Energy Independence and
Security Act biofuel mandates, for
example, the agencies expect the
amount of biofuel in the transportation
fuel market to increase significantly
over time, and the contribution of
feedstocks to change over that time as
well. Information that addresses
lifecycle emissions of biofuels would
need to take these considerations into
account.
The agencies believe that all of these
complex factors can be best addressed
by providing a great deal of relevant
information on a Web site, which can go
into considerable detail and be changed
and updated as appropriate. We
currently do not have a full lifecycle
analysis from which to draw for labeling
purposes across the full range of
vehicles and fuels. The information
reported to EPA on emissions from fuel
production varies across fuel types and
is much more detailed for gasoline
production. At the present time, it
would be difficult to represent
emissions from energy generation on a
national label in a way that is both
useful and accurate for consumers,
given regional variations, how
generation within regions is dispatched,
and access to green power purchases.
Therefore, EPA and NHTSA are
proposing that the label should limit
itself to tailpipe only emissions (clearly
identified as such) and include a more
complete discussion on energy
generation and lifecycle analysis on the
webpage. We believe that this approach
will prove sufficiently informative to
consumers. It also allows us the
opportunity to provide a fuller
discussion of GHG emissions associated
with energy generation for alternative
vehicles, as well as emissions from fuel
production (gasoline and biofuels). For
example, a Web site could provide
calculator tools that could reflect
regional variations in the GHG
emissions associated with electricity
generation as well as use national
averages. A Web site could also provide
information on the projected fuel
lifecycle impacts associated with
biofuels. The Web site could be updated
over time as the mix of electricity fuel
sources and biofuels changes. This
approach could help the consumer
understand over the lifetime of their
vehicles how their electricity generation
emissions impacts might be changing.
At this point in time, any effort to
provide complete lifecycle information
for fuels on the label could well produce
undue confusion. A label that clearly
presents tailpipe emissions appears to
be the best available way to combine
accuracy and disclosure, so long as
fuller information is available on the
Web site. The agencies believe that even
though many consumers will not visit
the Web site, it will be used by many
groups and organizations, and as a
result, the information that it provides
will be made available and used in the
marketplace. We seek comment on our
current view that the web is the better
place, compared to the label, to address
the complex issues associated with
emissions associated with electricity
generation and lifecycle emissions more
generally.
We invite both general and particular
comments on the proposed approach.
For example, we encourage commenters
to be as specific as possible with any
recommendations on how to address
fuel combustion/electricity generation
GHG emissions on the Web site. If
information on these emissions is to be
provided on a Web site, exactly what
information? The agencies specifically
invite comment on how to address fuel
combustion emissions associated with
the electricity used to power the
advanced technology vehicles starting to
enter commerce, such as electric
vehicles (EVs) and plug-in hybrid
vehicles (PHEVs). The agencies also
invite comment on how to address full
GHG emissions from biofuels on a Web
site. Should emissions be identified
specifically for the emissions associated
with the combustion of fuel to produce
electricity? Should such emissions be
determined on a regional or a national
basis? Should these emissions be
provided as a relative comparison to a
gasoline or diesel fuel, the current
predominant fuels?
For the convenience of commenters,
we have prepared the table below as an
illustrative example of one simplified
way that some lifecycle emissions
information related to electricity
production could be accounted for on a
Web site, based on certain
assumptions.118 It is important to note
that for comparison purposes, the
agencies would need to develop
methodologies to compare upstream
emissions impacts from all other fuels
as well, including diesel, renewable
fuels, and natural gas. Consistent with
the discussion above, it is important to
emphasize that the tailpipe + lifecycle
values in the table below are based on
2005 national average electricity GHG
emissions, and could be very different
for certain regions of the country today
and for the nation in the future if there
are major changes in the mix of methods

In general, for purposes of providing
information on the web, the agencies
invite comment on the appropriate
metrics to use and the specific
suggestions for content and format, if
appropriate. The agencies also request
comment on which web resources it
should prioritize for development that
would provide the most useful
information to consumers.
The agencies acknowledge that more
consumers will look at the label than at
the Web site, and that a ‘‘0’’ figure for
GHG emissions might prove confusing
to some consumers. While accurate and
more complete information will be
provided on the Web site, putting 0
grams CO2/mile on the label may lead
some consumers to perceive that driving
their EV does not contribute to GHG
emissions. With respect to the label
itself, the agencies are also requesting
comment on alternative options for the
label that, in addition to presenting
tailpipe emissions, refer to or identify in
some manner the emissions associated
with the lifecycle of the fuel. Under one
version of this alternative that is under
serious consideration, similar to a coproposal, the EV label would continue
to reflect the ‘‘0’’ CO2g/mile number
currently displayed on the co-proposed
labels (Figures III–2, III–10), but the
label would be modified by adding
either a symbol or an asterisk and
explanatory text which states, ‘‘The only
C02 emissions are from electricity
generation.’’ Likewise, the agencies
would modify the co-proposed PHEV
labels (Figures III–3, III–6, III–1, III–12)
inserting either a symbol or asterisk next
to the current CO2g/mile number
displayed with the following
explanatory text, ‘‘Does not include CO2
from electricity generation.’’
This alternative approach might
provide more accuracy and clarity for
purchasers by more explicitly indicating
that the CO2 emissions from generation
of electricity are not reflected in the
CO2 numbers on the label. Under this
alternative, FFV labels (for FFV vehicles
only) would continue to reflect the
gasoline only CO2g/mile number
currently displayed on the co-proposed
labels (Figures III–8 and III–14), but the
label (for FFVs only) would be modified
by adding either a symbol or an asterisk
VerDate Mar<15>2010
18:48 Sep 22, 2010
Jkt 220001
and explanatory text that might state,
‘‘The CO2 emissions listed here are from
gasoline combustion only. They do not
reflect the use of renewable biofuels.’’
The agencies request comment on this
alternative option.
The agencies are also giving
consideration to an approach that in
addition to the tailpipe emissions,
includes information on upstream
emissions on the label for the various
fuels. For electric vehicles, for example,
GHG emissions are (on an average basis)
a function of KwH per mile, and thus
could in principle be calculated, and if
a full or nearly full accounting could be
provided in a clear and intelligible form,
there would be advantages to providing
it on the label to consumers, in addition
to the tailpipe emissions data.
Therefore, the agencies invite comment
on the feasibility and usefulness of an
alternative approach that in addition to
identifying tailpipe emissions, would
include a separate value for upstream
emissions on the label as well as on the
Web site.
In particular, the agencies invite
comment on what type of information
should be considered as ‘‘upstream,’’
and whether a label including the
upstream emissions could be based on
national averages. The agencies might
consider making assumptions to
develop national averages.
Note, however, that agencies would
need to make a substantial number of
assumptions to develop such averages.
These include assumptions about the
overall impact on electric car recharging
on the grid mix, which would include
making assumptions about (1) the timeof-day distribution of recharging and (2)
the subsequent impacts on the base and
peak load electricity generation as well
as (3) the nature of regional variability
and (4) potential changes in the
electricity generation fleet. A relevant
source for this type of information may
be the Energy Information
Administration (EIA), which provides
estimates of the future electricity
generation mix, so there may be some
basis for estimating future GHG
emissions based on current state and
federal policies; but these estimates will
also rest on some uncertain
assumptions. The same type of analysis

(national averages for feedstocks and
fuel production) would need to be
developed and equivalent assumptions
made related to upstream emissions
from gasoline and diesel production as
well as renewable fuels, natural gas, and
hydrogen.
The agencies invite comments on
whether and how the possible inclusion
of upstream emissions information on
the label might affect other elements of
the label such as design, format,
presentation of the various ratings and
other information as well as the ranking
of vehicles on the label.
The agencies also recognize that
notwithstanding the many challenges, a
potential advantage of including
upstream emissions on the label is that
consumers may be able to compare
different EVs with respect to their
upstream emissions, as some will
require more energy per mile which
would likely result in different
upstream emissions impacts. Consumers
may be able to make similar
comparisons among EVs, PHEVs,
gasoline and diesel powered vehicles as
well as other fueled vehicles on the
basis of upstream emissions. Regardless
of what would be presented on the
label, the agencies will continue to
provide detailed information about the
lifecycle GHG impacts of different
vehicles on the Web site in a way that
may provide a better way for
individuals to take their region, driving
habits, and other specific factors into
account in their purchase decisions.
In view of the many assumptions the
agencies would need to make to include
upstream emissions on the label, we
emphasize that this alternative would
have to overcome several serious
challenges. We ask for comment on
whether and how each of those
challenges, outlined above, could be
addressed.
b. Energy Consumption Metrics
Energy consumption metrics are
another issue which becomes more
complicated with advanced technology
vehicles. For conventional gasoline
vehicles, the MPG metric has been the
foundation of the consumer label for 35
years. It is not a perfect metric, and
some have expressed concerns about its
E:\FR\FM\23SEP3.SGM
23SEP3
mstockstill on DSKH9S0YB1PROD with PROPOSALS3
58108
Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
‘‘non-linearity,’’ e.g., the absolute fuel
consumption savings associated with
improving one mile per gallon from 10–
11 MPG is over ten times greater than
the fuel consumption savings associated
with improving from 35–36 MPG as
discussed above. But, in some respects,
MPG has been a good metric for a
consumer information program: Lay
people had used the MPG metric prior
to its use on the label, the concept was
simple and understood by almost all
consumers, the practical range of 10–50
MPG was accessible to lay people and
facilitated simple calculations that most
consumers could perform, etc. The
results from recent EPA focus groups
conducted by the agencies were
unequivocal—the MPG values were, by
far, the most trusted and useful values
on the label.119
Unfortunately, while the miles per
gallon metric has been very useful when
99+% of all vehicles operated on
petroleum fuels, its usefulness as a
metric is less clear for a future vehicle
fuel such as electricity, which is not
measured in gallons, but rather in
kilowatt-hours. Therefore, for an electric
vehicle, or for an EREV PHEV when
operated exclusively on grid electricity,
there are three broad choices for a
consumption metric, independent of
statutory considerations, to characterize
the amount of electricity and all have
advantages and disadvantages:
• Kilowatt-hours. The rationale for
kilowatt-hours is that this is the metric
by which electricity is ‘‘counted’’ and
sold. In their monthly utility bills,
consumers are charged a certain rate (or
price) per kilowatt-hour, and this rate is
multiplied by the number of kilowatthours that the consumer uses, to
generate the overall monthly electricity
bill. This is analogous to what happens
at a gasoline service station, where a
consumer pays a certain rate (or price)
per gallon of gasoline, and this rate is
multiplied by the number of gallons of
gasoline that the consumer buys, to
generate the overall gasoline bill. The
primary argument against using
kilowatt-hours is that the focus groups
conducted by the agencies clearly
indicates that few consumers
understand what a kilowatt-hour is, and
most of the consumers who do not know
what a kilowatt-hour is say that they do
not want to learn.120

• Gallons of gasoline-equivalent.
From an engineering perspective, energy
can be measured, and different forms of
energy can be compared through the use
of energy unit conversion factors. For
example, a gallon of gasoline has the
energy equivalent of 33.7 kilowatthours, and any value for kilowatt-hours
can be converted to an energyequivalent value of gallons of
gasoline.121 For example, a vehicle that
used 33.7 kilowatt-hours would have
used an amount of energy equivalent to
1 gallon of gasoline, while a vehicle that
used twice as much electricity would
have used an amount of energy
equivalent to 2 gallons of gasoline. The
rationale for using gallons of gasolineequivalent is that consumers understand
the concept of ‘‘gallons’’ much more than
they understand any other energy
metric. In the focus groups conducted
for this rulemaking, the agencies found
that participants believed they
understood the equivalency approach
and felt comfortable with this metric
since it closely aligns with the miles per
gallon metric that they have always
relied upon.122 The primary argument
against using gallons of gasolineequivalent is that the concept requires
the conversion of one form of energy to
another, and while this reflects a
technical measurement of energy
equivalency, it may or may not be useful
to the consumer. For example, gasoline
and electricity are very different fuels in
many ways: How they are produced,
how consumers buy them and refuel,
whether consumer fuel expenditures
stay in the local or regional economy or
are exported, etc.
• A generic energy unit not directly
connected to either gasoline or
electricity, such as British Thermal
Units (BTUs) or joules. The argument
here would be to pick an energy metric
that is ‘‘fuel neutral.’’ The primary
arguments against this are both that few
consumers understand such a metric,
and that no motor fuels are counted or
sold in such units. While the agencies
recognize this as another conceptual
alternative, we have rejected this
approach.
As discussed previously, EPCA
requires that electricity use for EVs and
PHEVs on the fuel economy label is
converted to gallons of gasolineequivalent. But the statute also provides
discretion to EPA on the relative
prominence of a gallons of gasolineequivalent metric and a kilowatt-hours
metric.

For EV labels, the agencies propose to
show electricity consumption in both
metrics: As miles per gallon of gasolineequivalent (MPGe) and as kilowatthours per 100 miles. The agencies
recognize that higher MPGe values are
better, while lower kw–hr/100 miles
values are better. The agencies seek
comment on whether this is helpful or
confusing to consumers.
The most complicated advanced
technology vehicle in this regard is a
blended PHEV that is operating
simultaneously on gasoline and grid
electricity. There are two options for
energy metrics for blended PHEVs,
which are based on the general concepts
introduced above.
• Retain separate energy metrics for
gasoline and electricity. The gasoline
metric would continue to be miles per
gallon of gasoline (supplemented by a
gallons/100 miles consumption value as
well), while the electricity metric would
be kilowatt-hours of electricity (either
miles per kilowatt-hour or kilowatthours per 100 miles). The advantages of
this approach are (1) it includes the
values that EPA measures, (2) the
metrics reflect how these forms of
energy are counted and how consumers
pay for them, (3) the separate values do
not require judgments about whether
consumers ‘‘value’’ gasoline and
electricity equally or not, and (4) it
would avoid possible confusion over
what a combined miles per gallon of
gasoline-equivalent value means (i.e.,
some, maybe many, consumers would
probably assume that a miles per gallon
of gasoline-equivalent value was equal
to a miles per gallon of gasoline value,
which would be inaccurate). The
disadvantages of such an approach are
(1) few consumers understand the
metric of kilowatt-hours, (2) dual energy
metrics make it extremely difficult to
compare energy efficiency across
vehicles, and (3) those consumers who
focus only on miles per gallon of
gasoline and ignore kilowatt-hours of
electricity, will believe that a blended
PHEV is more energy efficient than it
actually is.
• Combine to a single energy metric
of miles per gallon of gasolineequivalent. This would require the use
of the conversion factor of 33.7 kilowatthours per gallon of gasoline-equivalent
value cited above. The advantages of
this approach are (1) it yields a single
value that simplifies the label and
facilitates vehicle comparisons, (2) it
avoids the kilowatt-hour metric that
consumers do not like or understand,
and (3) some consumers (though not all)
said they liked the concept of miles per
gallon of gasoline-equivalent. The
disadvantages of such an approach are
E:\FR\FM\23SEP3.SGM
23SEP3
Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
mstockstill on DSKH9S0YB1PROD with PROPOSALS3
(1) it requires the simplifying
assumption that all forms of energy (in
this case, gasoline and electricity) are
equally valued, (2) it does not allow the
consumer to see the individual energy
consumption values for gasoline and
electricity, and (3) it will yield labels
with both miles per gallon of gasoline
and miles per gallon of gasolineequivalent, which could be confusing to
some consumers.
The agencies are proposing to use the
miles per gallon of gasoline-equivalent
metric only for PHEVs, but seek public
comment on the relative merits of doing
so versus using the separate energy
metrics. The agencies believe that both
approaches have advantages and
disadvantages. In formulating comments
on this topic, commenters could also
consider three additional questions.
One, do consumers care equally about
gasoline and electricity, i.e., are they
just two different ways of fueling their
vehicles, with a Btu of gasoline
equivalent to a Btu of electricity, or do
some or most consumers care more
about one or the other form of energy?
Two, how should the agencies interpret
the focus group input in which most
participants indicated that they did not
understand kilowatt-hours on their
electric bills and did not want to have
this metric included on advanced
vehicle labels? Three, should we view
this as an opportunity to educate
consumers about the importance of
kilowatt-hours as a fundamental
measurement of electricity
consumption?
c. Driving Range Information (Including
5-Cycle Adjustment)
EPA does not include range
information on conventional fuel
economy labels. Petroleum fuels have
high energy densities and are stored onboard the vehicle in relatively cheap
and lightweight fuel tanks. The
combination of high driving range
values (gasoline vehicles typically have
ranges of 300–500 miles) and the fact
that range can be increased by simply
increasing the size of the fuel tank,
means that range for petroleum-fueled
vehicles has not been a top consumer
priority. In recognition of the fact that
non-petroleum fuels generally have
lower energy densities resulting in
reduced driving ranges than petroleum
fuels, the Federal Trade Commission
(FTC) requires a label that lists the
‘‘manufacturer’s estimated cruising
range’’ for alternative-fueled vehicles.123
The primary issue addressed in this
section is whether range should be
included on advanced technology
123 16
CFR part 309.

Jkt 220001
vehicle labels. For an EV, the primary
range parameter of interest would be the
miles that can be traveled between
battery charges. For an EREV PHEV, the
most important range parameter would
be the miles that can be traveled in allelectric mode. For a blended PHEV, the
primary range parameter would be the
number of miles over which the battery
is providing assistance in the form of
grid electricity, but it is also possible
that there could be some guaranteed or
likely all-electric range as well.
The primary arguments for including
range include (1) focus groups strongly
supported including the range for EVs
and PHEVs,124 (2) range is a critical
factor for what the consumer gets for his
or her investment in a more expensive
EV or PHEV, and is obviously a core
utility attribute for an EV and a primary
determinant of the overall
environmental and energy performance
of a PHEV, and (3) EPA can easily
measure range.
The arguments against including
range include (1) it is not a direct
measurement of energy or
environmental performance (in fact, for
an EV, other things being equal, a higher
range means a larger battery pack, a
heavier vehicle, and therefore higher
energy consumption, relative to the
same vehicle with a lower range and
smaller battery pack), (2) there will
likely be much greater variability in EV
range than we have faced with gasoline
fuel economy in the past, so there are
greater challenges involved in defining
a specific range estimate, and (3) adding
range would add to an already busy
label.
The agencies are proposing to include
range information on alternative
technology vehicle labels and seek
public comment on this issue.
A related issue is how EPA will
determine the appropriate adjustment
factor to use in converting 2-cycle test
values for range to 5-cycle test values for
vehicle labels. Under current EPA
regulations established by the 2006 fuel
economy label rulemaking, automakers
would have two choices: (1) Submitting
5-cycle test data, and (2) using the MPGbased (derived 5-cycle) equations.125
Using the MPG-based equations for EVs
would yield an approximate 40 percent
downward adjustment for EV range.126

125 71 FR77887–77888, Dec 27, 2006.
126 See 40 CFR 600.210–08. Using the equations
in these regulations to adjust 2-cycle test values for
extremely high MPG vehicles (or MPGe for EVs)
will result in adjustments approaching 40 percent.
Because the data used to determine these equations
did not include any such vehicles, EPA is uncertain
PO 00000
Frm 00033
Fmt 4701
Sfmt 4702
58109
EPA notes that there were no EV or
PHEV data in the database used to
generate the MPG-based equations, and
that the downward adjustment
appropriate for EVs (which have low
direct vehicle energy consumption
levels) is the result of extrapolating the
results of the conventional vehicle data
that was used to generate the equations.
EPA proposes a new set of options for
automakers to choose for purposes of
identifying the appropriate 5-cycle
range adjustment for EVs and the
electric portion of PHEV operation. One,
automakers could provide full 5-cycle
test data, which is one option under
current EPA regulations. Two,
automakers could provide vehiclespecific real world range data collected
from in-use vehicles. Three, automakers
could use the MPG-based equations
discussed above, but with the
downward adjustment capped at the
percent reduction represented by the
worst-case gasoline vehicle in the EPA
database. The worst-case gasoline
vehicle is the highest-MPG gasoline
vehicle, which is currently the Toyota
Prius. Based on the application of the
MPG-based equations to the Prius’ MPG
values, the Prius would get about a 30%
downward adjustment from its 2-cycle
data to its derived 5-cycle value, and
this would therefore be the level that
automakers could use for EVs and the
electric operation of PHEVs.
EPA seeks comment on this proposal
for the downward 5-cycle adjustment
for EVs and PHEVs.
d. Battery Charging Time Information
EPA does not include information on
the mechanisms for or time associated
with refueling vehicles on conventional
vehicle fuel economy labels. Refueling
with petroleum fuels is a fairly quick
and ubiquitous process, and has not
been a topic of consumer concern.
Refueling, or charging, a battery pack
will be different in many ways. While
gasoline vehicle refueling typically
takes 5–10 minutes, charging a battery
pack can take up to 12 hours or more,
depending on the charging hardware.
EPA focus group participants expressed
strong interest in including some type of
information on charging time on labels
for EVs and PHEVs.127
The arguments for including battery
charging time information on EV and
PHEV labels include (1) focus groups
supported doing so, (2) it is a core
consumer utility parameter (i.e., if the
charging time is so long as to be
as to the applicability of the formulae to EVs and
other extremely high MPG vehicles.

onerous, consumers will recharge less
frequently and this will have an effect
on the vehicle’s energy and
environmental performance), and (3)
EPA could develop a test procedure for
generating standardized information.
An example of a simple approach for
measuring EV recharge time would be to
use the method for recharging the
battery recommended by the
manufacturer and available to the
consumer. Full battery recharge time
could be defined as the time required to
charge the vehicle battery to full
capacity from the end of the electric
vehicle range test or ‘‘empty.’’ A fully
charged battery would be defined as the
same battery state of charge used to
determine electric vehicle range. EPA is
also seeking comment on partial
recharge time. Partial recharge time
could be measured and expressed as the
time of recharge required to travel a
given distance.
Arguments for excluding battery
charging time on EV and PHEV labels
include (1) there is only an indirect
relationship between charging time and
energy and environmental performance,
(2) EPA does not now have a test
procedure for generating standardized
data, (3) it will be fairly easy for
consumers and third parties to verify
automaker claims on this basic question,
and (4) adding battery charging time
will make the advanced technology
vehicle labels more cluttered.
The agencies seek comments on
whether we should include battery
charging time information on labels for
EVs and PHEVs.
e. Merged Vehicle Operating Mode
Information for PHEVs
Conventional vehicles have a single
‘‘operating mode,’’ i.e., all the powertrain
components contribute to propel the
vehicle at all times. Some advanced
technology vehicles have more than one
operating mode. For example, a blended
PHEV could have up to three operating
modes: An all-electric mode where the
vehicle is propelled exclusively by grid
electricity via the battery and electric
motor, a second mode where the vehicle
is propelled by a combination of both
grid electricity and an internal
combustion engine, and a third mode
that uses only the internal combustion
engine. For such vehicles, the agencies
propose to provide consumers with
basic performance information about
each of the PHEV’s individual operating
modes. One advantage of this approach
is that it will allow consumers to tailor
the information from the individual
operating modes to their own driving
habits, and therefore develop
‘‘customized’’ information relevant to
VerDate Mar<15>2010
18:48 Sep 22, 2010
Jkt 220001
their own situations. One issue is
whether the vehicle label should also
provide information that combines the
various operating modes into a single
‘‘merged’’ value reflecting an ‘‘average
driver.’’ One group that is developing
guidance for how individual operating
mode data could be combined for an
‘‘average driver’’ is the Society of
Automotive Engineers Hybrid Technical
Standards Committee,128 and the
agencies will continue to monitor the
work of this and other relevant
committees.
The rationale for including a merged
value is that (1) some consumers may
find information on the individual
operating modes to be ‘‘too much’’ and
may be more likely to pay attention to
a single set of performance information,
(2) few, if any, consumers will
exclusively drive in a single operating
mode, so some kind of combined
information could be helpful, (3) a
single, merged value can facilitate
comparisons across different vehicle
technologies and models and (4)
customers of this new technology will
not know how much they will operate
the vehicle in each mode, so an average
provides more complete information to
them.
The arguments against including
merged values are (1) the variability
between the performance values for
different operating modes can be very
large, and so any assumptions about an
‘‘average driver’’ will be accurate for
some consumers, but very inaccurate for
many other consumers, and (2)
including merged values, in addition to
individual operating mode values, will
add to an already busy label.
The agencies seek public comment on
the question of whether labels for
advanced technology vehicles with
multiple operating modes should also
include merged values that combine the
various vehicle operating modes, and if
so, on the best methodology for doing
so.
f. City/Highway Versus Combined
Values
EPA’s conventional vehicle labels
have long reported fuel economy values
for both city and highway driving. For
most conventional vehicles, highway
fuel economy values are typically 40–
50% higher than city fuel economy
values. The agencies believe that this is
another issue that is worth reexamining
with respect to advanced technology
vehicle labels.
Arguments for including separate city
and highway information on advanced
technology vehicle labels include (1)
128 SAE
PO 00000
J2841.
Frm 00034
Fmt 4701
Sfmt 4702
focus group feedback and other research
has consistently shown that consumers
find it useful to have separate fuel
economy values for both city and
highway driving for conventional
vehicles,129 and (2) since driving habits
can vary widely, separate city and
highway performance information can
be helpful to those consumers who want
to ‘‘customize’’ label information to their
own driving habits.
Arguments for not including separate
city and highway information on
advanced technology vehicle labels
include (1) some advanced technologies,
for example EVs, show less of a change
in energy consumption values between
city and highway driving than do
conventional vehicles which was one of
the primary reasons why EPA originally
displayed separate city and highway
MPG values on conventional fuel
economy labels, and (2) not reporting
separate city and highway values can
reduce some information by either a
factor of two (if a combined value is
shown instead of separate city and
highway values) or three (if city,
highway, and combined values were all
shown), thus reducing the ‘‘number of
numbers’’ on the label and possibly
making the labels more readable and
accessible for consumers. Focus group
participants, when viewing whole labels
for both conventional and advanced
technology vehicles, did not express a
preference for displaying city/highway
numbers for advanced technology
vehicles, although they did express a
clear preference for city/highway values
for conventional vehicles.
The agencies seek public comment on
the following questions related to
separate city and highway information
for advanced technology vehicle labels.
One, should EPA never report separate
city and highway values, always report
separate city and highway values, or
retain discretion for doing so only when
it is appropriate (i.e., when the
differences between city and highway
are significant enough to be
meaningful)? Two, would it be
acceptable for EPA to require the use of
separate city and highway fuel economy
values for conventional vehicles, but to
not do so, in some or all cases, for
advanced technology vehicles?
g. Methodology for Merged Values for
PHEVs
One specific issue for PHEVs is the
methodology for determining a single
merged value that combines the various

operating modes into a single overall
value, given that PHEVs use both
gasoline and grid electricity. The
agencies expect that consumers who
purchase a PHEV will do so with the
intention of utilizing the capability of
both fuels (e.g., it seems reasonable to
assume that most consumers who
purchase a more expensive PHEV would
then charge the PHEV as frequently as
possible in order to achieve fuel savings
by maximizing their use of electricity
and minimizing their use of gasoline). It
thus seems appropriate to include the
operation on both fuels in any merged
values, using a weighted average of the
appropriate metric for each of the modes
of operation. The agencies propose and
seek comment on using a methodology
developed by SAE and DOE based on
utility factors (UFs)—which predict the
fractions of total distance driven in each
mode of operation (electricity and gas)—
to assign weighting factors for gasoline
and electricity use for PHEVs for the
purposes of determining merged values
for fuel economy and/or greenhouse gas
ratings and for any other metrics for
which a single, merged value is
appropriate. The proposed UF
methodology is described in detail in
Section VI.B.
mstockstill on DSKH9S0YB1PROD with PROPOSALS3
h. Advertising Restrictions
The Federal lead on guidelines for the
use of vehicle label information in
automaker marketing campaigns rests
with the Federal Trade Commission
(FTC). The agencies believe that the
unique issues, as well as in the likely
increased complexity and ‘‘number of
numbers,’’ associated with advanced
technology vehicle labels, warrant
additional consideration of whether
there needs to be new guidelines for the
use of label information in private
marketing campaigns. The agencies
intend to raise this issue with the FTC,
and seek comments from the public that
could help inform our input to the FTC.
C. Labels for Other Vehicle/Fuel
Technologies
Labels for conventional gasoline and
diesel vehicles and for certain advanced
technology vehicles are the primary
focus of this proposed rule.
Conventional gasoline and diesel
vehicles are expected to make up a
majority of the fleet well into the future,
and improving on the communication of
conventional vehicle fuel economy and
related information is a continued
priority of EPA and NHTSA. Electric
vehicles and plug-in hybrid electric
vehicles are entering the fleet in the
near term, and there is the potential for
a rapidly increasing market penetration
of these vehicles in the future, yet
VerDate Mar<15>2010
18:48 Sep 22, 2010
Jkt 220001
labeling these vehicles in an
understandable and equitable way
presents significant challenges.
However, there are several other specific
vehicle technologies for which EPA
currently has labels, and EPA is also
proposing new label templates for those
as well.
1. Flexible Fuel Vehicles
Flexible fuel vehicles (FFVs) (also
called flex-fuel, dual-fueled or bi-fueled
vehicles) are vehicles that can operate
either on gasoline or diesel fuel, on an
alternative fuel such as ethanol or
methanol, or on a mixture of
conventional and alternative fuels.
Produced since the 1980s, flexible fuel
vehicles (FFVs) are the most numerous
of the currently available alternative
fuel vehicles, with dozens of 2010 car
and truck models available from General
Motors, Chrysler, Ford, Mazda,
Mercedes, Nissan, and Toyota.
Essentially all FFVs today are E85
vehicles, which can run on a mixture of
up to 85 percent ethanol and gasoline.
These vehicles are considered ‘‘dual
fueled vehicles’’ under EPCA, which
states that the label for dual fuel
vehicles must ‘‘indicate the fuel
economy of the automobile when
operated on gasoline or diesel fuel;
clearly identify the automobile as a dual
fueled automobile; clearly identify the
fuels on which the automobile may be
operated; and contain a statement
informing the consumer that the
additional information required by
subsection (c)(2) of this section is
published and distributed by the
Secretary of Energy.’’ 130
The current labeling requirements for
dual-fueled vehicles are consistent with
these requirements. While not required,
manufacturers may voluntarily include
the fuel economy estimates (and
estimated annual fuel costs) for the
alternative fuel on the label, in addition
to the gasoline information.131
Consumers can view the gasoline and
E85 fuel economy estimates of all FFVs
in the Fuel Economy Guide and at
https://www.fueleconomy.gov. In fact,
EPCA requires that the Fuel Economy
Guide contain information such as: (1)
The fuel economy when operating on
the alternative fuel, (2) the driving range
when operating on the alternative fuel,
and (3) information about how the
performance might change when
operating on mixtures of the two fuels.
EPA did not propose changes to these
requirements in the 2006 labeling rule
and did not seek comment on the topic.
However, EPA received late public

CFR 600.307–08(b)(14).

comments from several environmental
and consumer groups urging EPA to
require additional information on the
use of E85 on FFV labels. Since EPA did
not propose and request comments on
this topic in the 2006 rulemaking, the
agency did not finalize any such
requirements.
EPA and NHTSA request public
comment on three options for FFV
labels.
One option is to make no changes to
the current requirements for FFV labels
and continue to use fueleconomy.gov
and the Fuel Economy Guide to provide
information on E85 use to consumers.132
Consistent with the current
requirements, EPA and NHTSA would
finalize regulations that would allow
manufacturers to display the E85 fuel
economy values on the label on a
voluntary basis.133 The final regulations
would include a template for such a
label.
A second option is to require the
addition of E85 fuel economy values to
FFV labels using the units of miles per
gallon. Since E85 has a lower energy
density (i.e., about 25% less energy per
gallon) than gasoline, this means that,
other things being equal, an FFV will
have a lower fuel economy on E85 than
it will on gasoline. EPA recognizes that
this does not mean that ethanol is a ‘‘less
efficient’’ fuel than gasoline; in fact,
FFVs are typically slightly more
efficient on E85 than on gasoline in
terms of miles per unit of energy.
Accordingly, one approach under this
option would be to add text such as the
following wording on the label that
conveys this message: ‘‘While the E85
MPG values are lower than the gasoline
MPG values, the use of E85 is typically
slightly more energy efficient than the
use of gasoline.’’ Under this option, it
would also be possible to add E85
values for CO2 emissions (an FFV
typically emits slightly less CO2 per
mile on E85 than on gasoline) and fuel
costs (an FFV typically costs somewhat
more to operate on E85 than gasoline,
though this can vary by region). If CO2
values are not shown, it would also be
possible to include a statement such as
‘‘Using E85 uses less oil and typically
produces less CO2 emissions than
gasoline.’’
A third option is to utilize the concept
of miles per gallon of gasoline132 Consumers do get some information regarding
E85 efficiency on a label required by the FTC.
Currently the FTC label for FFVs displays the
driving range on both fuels and some additional
information regarding the use of alternative fuels.
See 16 CFR part 309.
133 Label examples for FFVs are shown in Section
III, but these reflect only a transition of the
currently used label content (some of which is
required by statute) to the proposed label designs.
E:\FR\FM\23SEP3.SGM

Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules

equivalent (MPGe), which is a way to
quantitatively account for the slightly
higher miles per unit of energy that an
FFV achieves on E85 relative to
gasoline. Because a gallon of gasoline
has about 33 percent more energy than
a gallon of E85, this means that an E85
MPG is multiplied by about 1.33 to
convert it to a MPGe value. For most
current FFVs, an E85 MPGe value will
be slightly higher than the gasoline MPG
value. The E85 MPGe value could be in
place of, or in addition to, an E85 MPG
value. As with the second option above,
CO2 and fuel costs values for E85 could
also be included.
The Federal Trade Commission (FTC)
currently requires the use of a label that
displays the cruising range of FFVs and
other alternative fuel vehicles. If the
agencies finalize one of the options to
include E85 information, and the FTC
determines that that information is
duplicative with its own information, it
opens up the possibility that the FTC
might review its requirement.
One remaining issue with FFVs is the
methodology for assigning an overall
combined value for greenhouse gas or
fuel economy-based ratings or for any
other metrics for which a single
‘‘merged’’ value is shown, given that two
different fuels can be used. There is
empirical evidence that approximately
99% of all FFV owners currently use
gasoline rather than E85 fuel. Given
this, the agencies propose, as a default,
to base any merged values for FFVs on
the assumption that the vehicle is
operated on gasoline 100% of the time.
However, if a manufacturer can
demonstrate that some of its FFVs are in
fact using E85 fuel in use, then the
merged values can be based in part on
E85 performance, prorated based on the
percentage of the fleet using E85 use in
the field. This approach is consistent
with that used for vehicle GHG
emissions compliance under the joint
EPA/DOT standards for 2016 and later
model year vehicles.134 The agencies
seek comment on applying the same
approach here.
2. Compressed Natural Gas Vehicles
EPA regulations currently provide a
label template for vehicles operating on
compressed natural gas (CNG), and
there is one major manufacturer
currently selling a natural gas vehicle in
selected markets. Given that a CNG
vehicle is a single-fuel vehicle, EPA
believes that the label designs
developed for conventional or other
alternative fuel vehicles can be easily
adapted to gaseous-fueled vehicles, as
has been done in the past. In fact, EPCA
134 75
FR 25433, May 7, 2010.
VerDate Mar<15>2010
18:48 Sep 22, 2010
Jkt 220001
provided specific instructions regarding
how to determine the fuel economy for
dedicated alternative fuel vehicles such
as gaseous-fueled vehicles. The statute
states that for dedicated automobiles the
fuel economy ‘‘is the fuel economy for
those automobiles when operated on
alternative fuel, measured under section
32905(a) or (c) of this title, multiplied
by 0.15.’’ 135 Section 32905(c) applies to
gaseous-fueled vehicles, and it requires
the following: ‘‘For any model of
gaseous fuel dedicated automobile
manufactured by a manufacturer after
model year 1992, the Administrator
shall measure the fuel economy for that
model based on the fuel content of the
gaseous fuel used to operate the
automobile. One hundred cubic feet of
natural gas is deemed to contain .823
gallon equivalent of natural gas. The
Secretary of Transportation shall
determine the appropriate gallon
equivalent of other gaseous fuels. A
gallon equivalent of gaseous fuel is
deemed to have a fuel content of .15
gallon of fuel.’’ 136
This methodology is currently
specified in EPA regulations. Note that
32905(c) applies a factor of 0.15, which
is essentially a ‘‘credit’’ that increases
the fuel economy of gaseous-fueled
vehicles by a factor of about 6.7 for the
purpose of CAFE calculations. But the
statute recognizes that incorporation of
this credit factor in the label values is
not appropriate, hence the provision in
32908(b)(3) to multiply the 32905(c)
result by 0.15, thus removing the credit
value and resulting in an appropriate
real-world label value.
The current EPA regulations interpret
the statute as requiring that the label for
CNG vehicles display a gasolineequivalent value, and a label template
for CNG is provided in the current
regulations.137 As can be seen, the
current label for CNG vehicles is
fundamentally the same as for gasoline
vehicles, except that the fuel economy
values are described as ‘‘gasoline
equivalent’’ values, and the estimated
annual fuel cost is based on a combined
city/highway gasoline equivalent value
and the price per gallon equivalent of
CNG. The current label also contains
text that reads ‘‘This vehicle operates on
natural gas fuel only. Fuel economy is
expressed in gasoline equivalent
values.’’
We are therefore proposing that labels
for CNG vehicles be essentially the same
in terms of content and appearance as

U.S.C. 32908(b)(3).

those proposed for conventional
vehicles, with only a few exceptions.
First, where the proposed labels
indicate the fuel type, labels for CNG
vehicles would state ‘‘Compressed
Natural Gas Vehicle.’’ Second, the fuel
economy value(s) would be stated as
gasoline-equivalent values. As is the
case for the proposed labels for electric
vehicles, the CNG labels would indicate
the conversion factor that is used to
determine the gasoline equivalent
values (0.823 gallons-equivalent per 100
cubic feet of CNG, as required by
statute).138 Third, the estimated annual
fuel cost would be calculated using the
combined city/highway gasoline
equivalent value and the cost per gallon
equivalent of CNG. The use of gasolineequivalent gallons is appropriate
because this is how CNG is dispensed,
priced, and sold at current CNG fueling
stations. Finally, because the cruising
range of CNG vehicles is typically
limited relative to conventional
vehicles, we are proposing the addition
of cruising range to the CNG vehicle
label (in this way the label would mimic
the electric vehicle label). As is the case
with electric vehicles, we believe that
range is a key piece of information for
the consumer who is considering a CNG
vehicle. Other information on the label,
such as the greenhouse gas and other
pollutant emissions and ratings, would
be determined from emission and fuel
economy test results and the proposed
calculation methodologies as is the case
for all vehicles.
Section III presents the proposed and
alternative label designs, including a
proposed design for CNG vehicles. We
request comment on the proposed
approach for CNG vehicles, and whether
there is additional information specific
to CNG or alternative fuels that should
be on the label.
3. Dual Fuel Natural Gas & Gasoline
Vehicles
Although there is currently a template
for dual fuel CNG/gasoline vehicles in
the existing regulations, there are no
manufacturers that are currently
manufacturing new vehicles that run on
CNG and on gasoline.139 Thus we
request comment on whether there is a
need to develop a template for these
vehicles based on the new labels. The
agencies envision that such a label
would be based largely on the proposed
approach for dual fuel gasoline/ethanol
vehicles discussed above, in that the
fuel economy and related information
138 49
U.S.C. 32905(c).
aftermarket fuel conversion companies
offer such vehicles, but EPA regulations do not
currently require fuel economy labels for
aftermarket fuel conversions.
139 Some

for both fuels would be displayed on the
label.
Although this proposal addresses
most current technologies, it does not
need to address every possible fuel and
technology combination either in
existence or that may emerge in the
future. EPA has the authority to
prescribe test procedures and label
content for vehicles that are not
specifically addressed by the
regulations, and expects to do so on an
as-needed basis to address new
technologies and fuels.140 In fact, EPA
expects to exercise this authority with
respect to labels for electric vehicles and
plug-in hybrid electric vehicles that
arrive on the market before the 2012
model year.
mstockstill on DSKH9S0YB1PROD with PROPOSALS3
4. Diesel Fueled Vehicles
EPA proposes to continue to calculate
the fuel economy of diesel vehicles in
miles traveled on a gallon of diesel fuel.
Diesel fuel has a long history of being
sold on a volumetric basis, and the
energy content difference between a
gallon of gasoline and a gallon of diesel
fuel is relatively small.
III. Proposed Revisions to Fuel
Economy Label Appearance
This section presents and requests
comment on three label designs. The
agencies are co-proposing Label 1 and
Label 2 design options, meaning that the
agencies currently expect to finalize one
of the two options. A third label design
is being presented as an alternative on
which the agencies are requesting
comment. All of these designs take into
account and meet the variety of
statutory requirements in EPCA and
EISA as discussed in Section I. It is
important to note that although all of
the label designs shown in this section
make use of color to varying degrees,
this Federal Register notice is capable of
only displaying gray-scale versions. Full
color versions can be viewed and/or

describe the use of color on the labels,
but interested parties should view the
color versions to understand the full
effect of the label designs.
Each design family consists of a set of
labels applicable to an array of vehicle
technology/fuel types. Specifically, we
show label examples that apply to
conventional vehicles (that is, vehicles
operating on a single fuel with internal
combustion engines or hybrid electric
drive), flexible-fuel vehicles (for
example gasoline-ethanol), compressed
natural gas vehicles, electric vehicles,
and plug-in hybrid electric vehicles.
Each label family could be readily
adapted to accommodate additional
vehicle technologies or fuels, such as
vehicles powered by fuel cells or other
upcoming technologies. The agencies
intend to finalize a label family with a
consistent look and feel across vehicle
types, in the belief that such consistency
will most effectively allow for
recognition of the label as well as
comprehension of its content.
The agencies found through the focus
groups and expert panel that many
consumers will view the fuel economy
label quickly, some using it to confirm
the vehicle information they have
previously researched on a
manufacturers’ website or a third party
website such as Consumer Reports or
Edmunds.com. Other consumers, in
contrast, will view the fuel economy
information for the first time when they
visit a dealer lot or showroom. While a
new vehicle purchase represents a
significant financial outlay, the agencies
learned through their research that
consumers like it simple, and do not
necessarily act on details. Therefore,
while the agencies want and need to
add certain pieces of information to
meet statutory requirements and to help
consumers make informed decisions
about the fuel consumption and
environmental impacts of their vehicle
choices we must balance these
objectives with the need to keep the
new labels consumer friendly. To
accomplish this, the agencies were
guided by a set of core principles in
designing these labels. The labels
should:
› Create an immediate first
impression for consumers.
› Be easy to read and understand
quickly.
› Clearly identify vehicle technology
(conventional, EV, EREV, PHEV).
› Utilize color.
› Chunk information to allow people
to deal with ‘‘more information.’’
› Be consistent in content and
design across technologies.
› Allow for comparison across
technologies.

› Make it easy to identify the most

friendly vehicles.
The agencies are requesting comment
on both the design and content of each
label. Design issues are self-evident on
the labels as presented, and we seek
comment on the design aspects of each
label family, including format, color,
font, and graphical elements. Content
issues have been extensively discussed
throughout the preamble; for illustrative
purposes, presentation of content varies
somewhat from one label family to
another and we seek comment on the
various approaches. Specifically, we
seek comment on the layout,
prominence, and grouping of label
elements in terms of clarity, apparent
relative importance, responsiveness to
consumer information needs, and
effectiveness at meeting public policy
goals. These sample labels do not
present every possible configuration of
each label; for example, gas guzzler
information is not depicted, as it is
utilized on only a small subset of labels.
The final rule will provide specific
templates for these unique cases.
Detailed specifications for presenting all
required label information will be
included in the regulations.
Although we will finalize labels with
a uniform look and feel, commenters
should not view the content of the
labels below as being necessarily tied to
one label design. For example, just
because Labels 1 and 3 for PHEV are the
only labels that display the all-electric
range for a PHEV does not mean that the
information could not be incorporated
into Label 2 or into other label designs.
We are interested in comments that
relate both to content that should be on
the label, how it should be
communicated, and what overall label
presentation is most effective and
consumer friendly.
Finally, please note that although the
agencies have made every effort to make
these labels as realistic as possible and
to ensure that the values on each label
are internally consistent, the labels
presented here should be considered
examples that are not intended to
represent real automobiles.
A. Proposed Label Designs
The agencies are proposing two label
designs, presenting both designs as
equal ‘‘co-proposals’’ but expecting to
finalize only one design based on public
comments and other information
gathered after the proposal. Although
the two designs shown below have
fundamentally different visual
appearances and will no doubt elicit
very different reactions from some
viewers, they essentially present exactly
E:\FR\FM\23SEP3.SGM
23SEP3
58114
Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
the same basic information. For
conventional vehicles, for example,
each design displays the following:
• City MPG.
• Highway MPG.
• Combined gallons/100 miles.
• CO2 grams per mile (combined city/
highway).
• Estimated annual fuel cost.
• Range of fuel economy within the
class.
• The fuel the vehicle uses.
• Three ‘‘slider bars’’ showing the
performance of the labeled vehicle
relative to other vehicles for MPG, CO2,
and other air pollutants.
• Annual fuel cost assumptions.
• A symbol that can be read by a
‘‘‘Smartphone’’’ for additional consumer
interactions (i.e., a ‘‘QR’’ Code).
• A Fuel Economy Guide statement.
• EPA, DOE, and DOT logos.
1. Label 1
mstockstill on DSKH9S0YB1PROD with PROPOSALS3
Label 1 is fundamentally different
from Label 2 and 3 designs presented in
this section in three different ways:
• First, the orientation is a portrait
orientation, rather than the landscape
style of the current label.
• Second, a rating reflecting the
energy efficiency and environmental
impacts of the vehicle is given overall
prominence. Instead of providing a
series of numbers on the label with
VerDate Mar<15>2010
18:48 Sep 22, 2010
Jkt 220001
varying or equal prominence, which
may make it difficult for consumers to
evaluate at a glance, this label presents
the energy and environment rating as a
letter grade (a system familiar to all
consumers) with major prominence at
the top of the label. The letter grade is
simply another familiar scale on which
to present a linear rating, comparable to
the star system or a 1–10 rating. This
grade would be based on CO2 emissions
and fuel economy consumption as
described in Section II. To further help
consumers identify the grade of a
vehicle on the dealer sales lot, the
agencies are proposing that different
colors be used to differentiate between
grade ‘‘families.’’ In other words, the
dominant color on all the ‘‘A’’ grade
labels would be one color, the ‘‘B’’ grade
labels would use a different color, and
so on. For example, the circle which
surrounds the letter grade would be a
different color depending on the grade.
The color versions of the labels
demonstrate this, using green for A
grades, yellow for B grades, orange for
C grades, and a dark orange for D grades.
• Third, this label provides new fuel
cost savings information not seen on
any other label designs. Secondary only
in prominence to the letter grade, and
immediately below the letter grade,
Label 1 would display the 5-year fuel
cost of the vehicle in comparison to the
PO 00000
Frm 00038
Fmt 4701
Sfmt 4702
average vehicle. For vehicles with fuel
economy ratings above the median
vehicle, the label would display how
much the consumer would save, and for
vehicles with ratings below average the
label would display how much more the
consumer would be spending.
All the remaining information is
displayed in the bottom portion of the
label and would be available to
consumers who want to know the more
detailed information or who take a more
analytical approach to evaluating the
vehicle. The agencies believe that this
approach uses a rating system that is
easily understood by consumers and
that would dramatically simplify the
process of evaluating the overall energy
efficiency and environmental impacts of
the vehicles they are considering. The
de-emphasis of MPG on this label—
indeed, one purpose of directing
consumers to the overall rating—is
intended to enable consumers to make
the best fuel consumption and
environmental choices, choices made
easier by the addition of the
comparative cost information.
Additionally, a consumer that uses the
letter grade and cost information on this
label may be able to avoid the effect of
the ‘‘MPG illusion’’ described in Section
II.

IV. Agency Research on Fuel Economy
Labeling
As discussed above, the fuel economy
label must contain certain pieces of
information by statute, and may
additionally contain other pieces of
information considered helpful to
consumers. Given that all of the label
information must be presented so as to
maximize usefulness and minimize
confusion for the consumer, EPA and
NHTSA embarked upon a
comprehensive research program
beginning in the fall of 2009.
Developing an effective label—one that
conveys the required and desired
information to consumers so that they
can understand and use it to make
decisions—involves some inherent
subjectivity, since what is
understandable and useful for one
consumer may be confusing or
unhelpful to another. To better ground
our proposed label designs in actual
human responses, the agencies set out to
better understand the following general
issues: whether, how, and to what
extent consumers use the current fuel
economy label in the vehicle purchase
process; the barriers to consumer
understanding of the fuel efficiency of
vehicles relative to one another
(including both conventional vehicles
and advanced technology vehicles); and
how a newly redesigned label could
most effectively convey information to
consumers on fuel economy, fuel
consumption, fuel cost, greenhouse gas,
and other emissions.
When EPA last redesigned the fuel
economy label in 2006, consumer
research was valuable in helping to
inform the development of that label.142
Since today’s proposal includes adding
important new elements to the existing
label as well as creating new labels for
advanced technology vehicles, EPA and
NHTSA embarked on a more
comprehensive consumer research
program than that undertaken in 2006
and have used this research to help
develop the labels proposed in this
NPRM.
2. Focus Groups
A. Methods of Research
To gather information about the topics
described below, the agencies designed
a research plan including a review of
literature on the vehicle buying process,
three sets of focus groups in four
different cities, a day-long facilitated
consultation with experts in the field of
shifting consumer behavior, and an
internet survey of responses to proposed
label designs (which will occur during
The agencies felt it was critical to
consider understandability and
consumer reaction to a variety of label
concepts given that the purpose of the
fuel economy label is to inform
consumers of the vehicle’s fuel economy

EISA, greenhouse gases and other
emissions. EPA and NHTSA
additionally saw a need to conduct
research beyond that of the previous

1. Literature Review
EPA and NHTSA conducted a review
of the existing literature to understand
the vehicle buying process. Specifically,
the literature review addressed the
sources of information that consumers
use to research vehicles, their decisionmaking process, and the factors that
influence which vehicles consumers
choose to buy. These include vehiclespecific factors such as price, fuel
economy, and safety, as well as the role
that demographics and psychographics
play in purchasing decisions. Literature
examining consumer attitudes toward
buying more fuel efficient and
environmentally friendly (i.e., ‘‘green’’)
vehicles was also reviewed.
Understanding when and how
consumers consider fuel economy and
the environmental impact in their
vehicle purchase decisions helped the
agencies determine the most effective
ways to provide useful information to
consumers on the vehicle label.
Additionally, the literature review
report included an overview of existing
educational campaigns aimed at helping
consumers use information on the fuel
efficiency and the environmental effects
of their transportation choices. Review
of these campaigns may help inform the
agencies’ development of educational
tools and messages beyond the label to
provide consumers with useful
information on fuel efficient and
environmentally friendly vehicles.
A broad range of sources were
reviewed for this report, including
journals in marketing, economics, and
transportation research; business
magazines; government documents;
conference proceedings; and a variety of
websites. Some of the key findings from
the literature review are described in
Section IV.B. A more detailed report is
available in the docket.143

rulemaking due to the advancements in
vehicle technology underway, the
increased market share of vehicles that
use fuels other than gasoline, and the
introduction of environmental
information to the label. The agencies
determined that they would gather indepth, qualitative feedback about fuel
economy labeling, potential new label
information, and ways of displaying the
information through focus groups. The
focus group format allowed for in-depth
probing around a variety of topics,
including comprehension of potential
elements on the fuel economy label and
how consumers may use that
information in making purchase
decisions. The focus groups were not
intended to provide quantitative results,
but were instead designed to help EPA
and NHTSA discern the subtleties of the
large number of decisions that are
necessary when creating a label that
should convey numerous and
sometimes complicated information.
The focus group process included a
recruitment screener, on-line pre-focus
group survey, and at least two genderdifferentiated focus groups in four
different cities for each of the three
separate phases. The focus group
methodology and results, including the
recruitment screener and pre-focus
group on-line surveys, are discussed in
greater detail in the focus group
Technical Memoranda available in the
public docket for this rulemaking.144
The agencies concluded that
conducting three phases of focus
groups, each with a different
concentration, was necessary to gather
adequate information to explore the
complex and numerous issues raised by
this rulemaking. Phase 1 gathered
qualitative information on consumer
understanding and use of the current
fuel economy label, consumer reaction
to potential new information and
metrics on the label for conventional
vehicles, and also initial identification
of effective displays for this
information. Phase 2 asked consumers
to identify what information they were
interested in seeing on the label for
advanced technology vehicles and
explored the understandability and
sufficiency of various information and
metrics for PHEVs and EVs. Phase 3
explored the understandability and
usefulness of new information
integrated into whole label designs for
both conventional and advanced
technology vehicles. Thus, overall,
focus groups were used to obtain a
qualitative understanding of consumers’
comprehension and reactions to fuel
economy label information.

The agencies assumed that
individuals who had recently purchased
vehicles would have the best insight
into how the current fuel economy label
is used and would therefore also be best
suited to provide input about any
changes that might be made to the label.
To that end, participants were selected
based on having purchased a vehicle
within the past year, but not during the
‘‘cash for clunkers’’ purchase
window.145 A ‘‘participant screener’’
was used to ensure a reasonable crosssection of purchasers was represented in
each group. Some of the demographic
variations purposefully considered
included the type of new vehicle
purchased, price range of the new
vehicle, average daily driving distance,
and whether the individual had
seriously considered or actually
purchased an advanced technology
vehicle such as a gasoline hybrid.
Each focus group participant was also
asked to complete a short on-line survey
before attending the session. This
survey served three purposes: (1) To
collect demographic data about the
participants and information about their
specific vehicle purchase process; (2) to
provide participants with some
background information about advanced
technology vehicles so that the
participants would have some exposure
to new technologies prior to the focus
group meeting; and (3) to gather
information about how the participants
had used the current fuel economy label
in their purchase decisions, if at all.
This survey data was not intended to be
examined as a nationally representative
sample and was only used as
supplementary information when
describing the focus group results.
The agencies anticipate that there will
be additional focus groups prior to rule
finalization in each of the four cities
where focus groups were held preproposal. These focus groups will
examine revised labels based on
feedback the agencies receive during the
comment period and will provide
additional input on whole label designs.
The agencies will place information
obtained from these focus groups in the
docket as it becomes available and
encourages all interested parties to
check the docket for updated
information.
145 ‘‘Cash for Clunkers’’ (Consumer Assistance to
Recycle and Save Act of 2009, Pub. L. 111–32) was
a NHTSA program that provided a tax incentive to
trade-in low fuel efficient vehicles for new, higher
fuel efficient vehicles. The purchase period in
which this program operated was excluded to avoid
any bias of participants, since the program was
explicitly focused on fuel economy.

3. Internet Survey
While the focus groups were used to
develop new label designs, the internet
survey is meant to examine how
understandable the new label designs
are, and whether the proposed new
label and alternative labels will improve
consumers’ knowledge about more
efficient vehicles. The planned survey is
scheduled to begin concurrent with the
signing of this proposal and will test
these questions for both conventional
and advanced technology vehicles. A
notice of the survey, published in the
Federal Register on May 12, 2010,
requested comment on the survey
methodology.146 No substantive
comments were received.
This survey will use two samples:
Self-selected U.S. new vehicle
purchasers and people who expressed
an intention to purchase a new vehicle
by requesting a price quote from a
dealer.147 Each of these samples is
divided into three separate groups. One
version of the survey was developed for
each group, identical in every way
except that each of the groups will see
only one of the label designs.
The survey tests respondents’
understanding of the labels by showing
each respondent a series of label pairs.
In each pair, all vehicle characteristics
are held constant except the information
on the vehicle label. For instance, the
fuel economy of the vehicles may differ,
or one may have a conventional vehicle
and one an electric vehicle.
Respondents are then asked to identify
which vehicle is better to use for trips
of specified distances.148 The key metric
of interest is whether the label designs
produce statistically significantly
different results. If one label produces
more correct responses than other
labels, then it can be considered more
understandable; if the labels do not
produce statistically different results,

Activities; Proposed Collection; Comment Request;

Economy Label Design and Content; EPA ICR No.

26751 (May 12, 2010).
147 Sources of respondents were databases owned
by Autobytel, https://www.autobytel.com (for those
intending to buy new vehicles), and Focus USA (for
those who purchased a vehicle in the last year),
https://www.focus-usa-1.com.
148 Respondents were asked which was better,
rather than which was more fuel-efficient or less
costly, so as to leave the respondents with the
choice of what information on the label to use for
the comparison. A later question asked which
information they used in their response. While this
somewhat ambiguous approach may reduce the
absolute number of correct answers to the
questions, the goal is testing the relative effects of
the labels, not the absolute effects.
PO 00000
Frm 00056
Fmt 4701
Sfmt 4702
then the labels can be considered
equivalently understandable.
To test the potential influence of the
labels on vehicle purchases,
respondents see pairs of labels for
vehicles with all vehicle attributes
constant except those varied on the
label, such as the technologies of the
vehicles, their efficiencies, and their
energy costs. Instead of using the label
to identify the better vehicle for a
scenario, the respondents are asked
which of these vehicles they would
prefer to buy, based on their individual
driving patterns. Comparisons involve
both conventional and advanced
technology vehicles. Because the survey
asks respondents about their typical
daily driving distances, it is possible to
see whether respondents chose the
vehicle better suited for their habits.
The key variable is whether the
responses differ for different label
designs.
The Internet survey data collection is
planned to occur in early to mid-August
2010. The results of the survey will be
made public as soon as they are
available. The results will be made
available in the public docket for this
rulemaking at regulations.gov. If the
results are not placed in the docket 30
days before the end of the comment
period, the agencies will accept
comments on these results up to 30 days
from when they were placed in the
docket.
4. Expert Panel
In order to gather additional feedback
on the label designs developed from the
focus groups and to identify
opportunities and strategies to provide
more and better information to
consumers so that they can more easily
assess the costs, emissions, and energy
efficiency of different vehicles, EPA and
NHTSA convened an expert panel.
‘‘Experts’’ were selected based on their
past experience in changing social
norms either by successfully launching
new products or leading national
education campaigns that have had a
broad and significant impact. The
method for selecting the panel began by
first generating a list of products and
social changes that met the criteria of
impacting a significant percentage of the
population quickly, while also
demonstrating staying power.
Individuals who had roles critical to the
success of these efforts were then
identified and recruited. Nine ‘‘experts’’
participated on the panel, with
experiences that included launching
very successful public health
campaigns, Internet sites, new
technologies, and cable networks. The
E:\FR\FM\23SEP3.SGM
23SEP3
Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
meeting was held from 9 a.m. to 3 p.m.
in Washington, DC on June 9, 2010.
The topics covered include:
Background information, review and
feedback on the EPA/NHTSA research
process, messaging techniques, outreach
strategies, and feedback on possible
label designs. The Expert Panel is
discussed in greater detail in the Expert
Panel Report in the public docket for
this rulemaking.149
B. Key Research Questions and Findings
The agencies identified the following
key research questions, given the
overarching issues provided above:
• How should labels portray
information about fuel consumption and
fuel economy, fuel cost, greenhouse gas,
and other emissions for consumers in a
way that is most understandable and
useful to them?
• How should labels for advanced
technology vehicles portray information
about fuel economy, fuel cost,
greenhouse gas, and other emissions for
consumers in a way that is most
understandable and useful to them?
• How should the new labels be
designed to meet the statutory
requirements while best raising
consumers’ understanding of fuel
efficiency, fuel cost and environmental
impact?
• How can consumers compare
vehicles when they are shopping?
• What purchase process do
consumers currently use to make new
vehicle purchasing decisions? Given
this process, when are the most effective
opportunities to communicate fuel
economy and environmental
information?

1. Effective Metrics and Rating Systems
for Existing and New Label Information
How should labels portray
information about fuel consumption and
fuel economy, fuel cost, greenhouse gas,
and other emissions for consumers in a
way that is most understandable and
useful to them?
As described in Section I, EPCA and
EISA require the fuel economy label to
provide fuel economy, cost, and
environmental information, as well as
provide a means to compare vehicles
based on fuel economy, greenhouse
gases, and other emissions. The agency’s
research program explored how this
information might be displayed on the
label in a useful and accessible format
for consumers.

a. Fuel Consumption and Fuel Economy
EPCA requires the label to display the
‘‘fuel economy of the automobile.’’
However, fuel economy, commonly
thought of as ‘‘MPG’’ (the number of
miles that can be traveled consuming
one gallon of fuel) is often
misunderstood by consumers. As
discussed more extensively in Section
II, because MPG is not linear, when
people compare vehicles with different
MPG values they are apt to incorrectly
estimate the fuel savings of one vehicle
over another. For example, switching
from a 15 MPG vehicle to a 20 MPG
vehicle will save more fuel than
switching from a 30 MPG vehicle to a
35 MPG vehicle. Thus, comparing
vehicles based on MPG is not as helpful
to consumers in making quick and
accurate comparisons as consumers may
believe it to be. Fuel consumption (the
number of gallons of fuel consumed to
travel a given distance), on the other
hand, does yield the type of linear
comparison that consumers should find
useful. Therefore, the agencies explored
ways to convey fuel consumption on the
label.
Focus groups were instrumental in
helping the agencies learn about
communicating fuel consumption.
Specifically, Phase 1 focus groups set
out to gauge how receptive consumers
were to a fuel consumption value and
whether there were particular
presentations of that value which were
more understandable. To do this the
‘Fuel Economy (MPG) Illusion’ was
introduced in the pre-focus group online survey, followed by specific
probing in each group around what ‘‘fuel
consumption’’ means. Phase 1 focus
groups generally responded that it was
the distance one can travel on a gallon
of gas (which is fuel economy, rather
than fuel consumption). Following this
discussion the participants were
presented with four different designs,
each conveying fuel consumption and
fuel economy information. The
prominent value displayed within each
design was fuel consumption, given in
gallons per 100 miles while the less
prominent value was fuel economy,
given in miles per gallon. Even when
participants demonstrated that they
properly understood fuel consumption,
most still indicated that they preferred
miles per gallon over gallons per 100
miles. Participants indicated this to be
the case even after the moderator
explained the ‘MPG Illusion.’ A few
participants did indicate that viewing
gallons per 100 miles, instead of miles
per gallon, might get them to switch to
more efficient vehicle types. Some
participants also said that they believed
PO 00000
Frm 00057
Fmt 4701
Sfmt 4702
58133
they would use the gallons per 100 mile
fuel consumption information on the
label to learn about the vehicle’s city
and highway gas consumption and to
compare between different vehicles in
making their purchase decision.
However, most participants were not
enthusiastic about using the fuel
consumption information.
Almost all focus group participants
showed a strong attachment to MPG.
They like and use the city and highway
MPG and are not familiar with gallons
per 100 miles. If a new fuel
consumption metric, such as gallons per
100 miles, were added to the label
participants would still want the
familiar MPG metric to be prominent on
the label. Recognizing that consumers
believe they derive significant value
from MPG, but that consumption
information may be more accurate and
ultimately valuable to consumers,
another approach to displaying fuel
consumption was also devised and
presented to focus groups: An ‘‘annual
gallons used’’ value. The basis for
deriving this new metric was that (1) it
makes the magnitude of comparing
vehicles based on consumption more
apparent, and (2) it provides a clear link
between the annual cost value and fuel
consumption value. An annual gallons
metric was also found to be one of the
more effective ways to demonstrate the
fuel economy illusion. While the
agencies considered displaying the
annual gallons of fuel information on
the label we ultimately determined that
the gallons per 100 mile metric should
be introduced on the label as the new
consumption metric, and that the
introduction of the five year cost or
savings information would also help
consumers in overcoming the effects of
the MPG illusion while also providing
important additional information.
Phase 1 focus group participants also
evaluated four different graphical
display options for fuel consumption
and were asked which was the most
understandable design. Participants
responded by identifying the design
they felt was simple, informative and in
a familiar format. However, participants
did not agree on which design
accomplished this.
The agencies further explored fuel
economy and fuel consumption designs
in Phase 3 where focus group
participants were asked to evaluate
whole label designs encompassing both
fuel economy and fuel consumption
values. In each of the three labels
presented, the MPG value was a

dominant metric.150 For each design
participants were asked to determine
between two labels, which represented
the more fuel efficient vehicle.
Participants were also asked to identify
what piece of information on the label
they used to make this determination.
Fuel consumption was rarely identified
as being used by participants. Instead,
participants used MPG and cost values
most often.151
In Phase 3, the agencies explored
simplification of the labels by
displaying on two of the three label
designs only the combined (55% city
and 45% highway) fuel economy value
in lieu of listing the city and highway
values separately. (See Section IV.B.4
for a discussion of whole label designs
and why simplification is perceived as
an overarching goal.) When participants
were probed about why they did or did
not like certain label designs, the
presence of city and highway values
was often cited as a positive for a label
design, and the absence of the city and
highway values was cited as a negative
for a label design. In addition, when
asked how to improve the label designs,
several focus group participants asked
for the city and highway values to be
added to the label designs that did not
include them.
The agencies gathered additional
input on the most effective approaches
for portraying fuel economy and fuel
consumption information during the
expert panel meeting. After viewing
three label designs, expert panel
participants provided comments on how
the label could be made more
understandable and useful for
consumers. The expert panel
emphasized that in order to be effective,
the fuel economy label should be simple
and able to be understood by consumers
within a short amount of viewing time.
To implement this goal, the expert panel
suggested that the agencies develop a
single, overall metric for vehicles that is
easy for consumers to understand, such
as a letter grade (A ±, B ±, etc.).152
The expert panel also suggested that
the agencies consider redesigning the
label such that the single metric is
prominently featured on the top half,
and any additional vehicle information
and more specific metrics be included
on the label in smaller font and in a less

prominent location. The expert panel
stated that this approach would provide
interested consumers with more
detailed information without distracting
from the simpler, overall metric that all
consumers could easily understand. The
rationale for this label design is that it
can provide useful comparative
information to the consumer who may
only glance at it, while also providing
the necessary details to those who want
more in-depth information.
Additionally, the expert panel suggested
prominently featuring a website URL
and a QR Code® for smartphones to
provide consumers with access to more
detailed vehicle information
elsewhere.153 For example, the website
and smartphone application might
contain tools for consumers to calculate
the fuel economy they can expect based
on their own driving habits or allow
consumers to quickly compare fuel
economy and consumption for different
vehicle models.
etc.). When Phase 1 focus group
participants were presented with a
variety of cost units, the two most
popular choices among cost units were
annual cost and cost per month.
However, in Phase 3, when presented
with labels that displayed both a
monthly cost and an annual cost,
participants suggested that the monthly
cost value could be dropped.
Participants in the expert panel
meeting suggested that the agencies
provide information on the savings
consumers could achieve by purchasing
a more fuel efficient vehicle. One expert
panel participant noted that the current
label designs demonstrate costs, but that
it would be better to demonstrate
savings, which tends to be a very strong
motivator.155 One approach to
communicating this information on the
label would be to display the savings a
consumer might expect over five years
by purchasing and driving a vehicle
with a higher overall letter grade.
b. Fuel Cost
EPCA requires the fuel economy label
display the ‘‘annual fuel cost of
operating the automobile.’’ Recognizing
that some consumers have previously
appeared to distrust or dismiss annual
costs as not representative of their own
experience, EPA and NHTSA explored
whether there were other cost units
(such as cost per month, per mile, per
week, etc.) that could be additionally
provided that would be more
meaningful to consumers.
Throughout the focus groups in Phase
1 and 2, participants indicated that they
tended to dismiss the annual cost
information on the current label because
gas prices fluctuate and vary with
location, and they do not drive 15,000
miles per year.154 Nevertheless, Phase 1
focus group participants identified the
estimated annual fuel cost as the second
most used piece of information on the
label. In addition, in Phase 2 focus
groups, where participants were asked
to create labels from scratch, most
groups placed a cost value on the label.
When cost values are used, focus group
members indicated they used it as a
comparative tool to evaluate the fuel
efficiency of different vehicles.
When asked what they thought about
cost, focus group participants indicated
they thought about the cost to fill a gas
tank, the fuel cost over a period of time
(daily, weekly, monthly, yearly, etc.),
and the fuel cost over a given distance
(cost per mile, 100 miles, 1000 miles,
c. Environmental Metrics
Environmental information on
greenhouse gases (GHGs) and other
emissions has not been previously
displayed on the fuel economy label, so
the agencies were interested in learning
how a label might best convey to
consumers information about the
emissions impact of a new vehicle. The
available literature on the impact of
‘‘eco-labeling’’ vehicles is mixed.156
Some of the research indicates that
consumers may welcome an eco-label
on their vehicle, although they say that
it is unlikely to impact their purchase
decision. Through its consumer
research, the agencies investigated what
combination of metrics and ratings
might be displayed on the fuel economy
label to provide this information in an
effective and consumer-friendly way,
including a stand-alone CO2
performance metric, relative versus
absolute rating systems, a comparison
system, and an environmental
certification mark.
For the most part, Phase 1 focus group
participants indicated that they did not
research environmental information
(beyond fuel economy) as part of the
vehicle purchase process. While some
participants indicated that they would
use environmental information to
compare different vehicles if it was
placed on the fuel economy label the
majority of focus group participants
were indifferent to the inclusion of

environmental impact information on
the label and indicated they were not
likely to visit a website for
environmental information. However,
when presented with whole label
designs in Phase 3 many respondents
indicated that the environmental metric
should be on the label, so that it is
available for those who were interested.
In Phase 1, participants were
presented with four different
environmental metric options and
approaches to displaying environmental
information, and were asked to rate the
most understandable and least
understandable. Participants stated that
they understood the environmental
information in general, but did not
understand what ‘‘grams of CO2’’ meant.
The display featuring a rating for other
emissions in stars and grams of CO2
numerically was most frequently chosen
by Phase 1 participants to be the most
understandable. Participants generally
favored presentations that showed
information in a simple format, though
there was no consensus on which
format achieved this. In general Phase 1
and 2 focus group findings indicate that
we must keep environmental
information simple if we want
consumers to pay any attention to this
information on a label. An overall
environmental rating was most
favorably received with the general
reaction being that EPA was trusted to
decide how to combine environmental
impacts into a single rating.
Phase 1 focus groups were also asked
if they recognized and knew what the
‘‘SmartWay’’ logo meant. None of the
participants recognized the logo.
However, when probed, most
ascertained that it was an EPA
designation of some sort. While some
participants indicated the logo may
confer credibility to an environmentally
friendly vehicle, none indicated they
would be less likely to purchase a
vehicle without the logo.
In Phase 3 focus groups the agencies
sought to examine further how
environmental information might be
displayed most effectively. Several
permutations of graphical rating systems
were shown to participants. These
included designs in which ‘‘greenhouse
gases’’ and ‘‘other air pollutants’’ were
displayed as one combined
environmental rating or separately.
Rating scales were examined that were
based on relative values, such as a ‘‘5
leaf’’ rating system as well as a linear
scale that had the vehicle’s absolute CO2
value identified on a scale that had endpoints identifying the approximate
VerDate Mar<15>2010

highest and lowest emitting vehicles
available.157
The expert panel, when shown the
labels designed by the agencies based on
focus group input, stated that they
neither understood the environmental
information presented nor found it
compelling. As described in Section
IV.B.4, the expert panel recommended
developing an overall rating for
vehicles, which could combine fuel
economy and environmental impacts.
The expert panel noted that additional
metrics (e.g., CO2 performance) could be
included in a less prominent position
on the label for consumers interested in
more detailed environmental
information. Expert panel participants
also suggested that environmental
performance information could be made
available on a website and accessed
through the smartphone interactive (QR
Code®) featured on the label.158
2. Effective Metrics and Ratings Systems
for Advanced Technology Vehicles
How should labels for advanced
technology vehicles portray information
about fuel economy, fuel cost,
greenhouse gas, and other emissions for
consumers in a way that is most
understandable and useful to them?
In addition to the issues discussed
above for conveying information
generally on labels, advanced
technology vehicles that operate on
fuels which differ from conventional
gasoline and diesel fuel require new
strategies to communicate and display
fuel economy information effectively.159
Through the research program, we
explored potential approaches to
communicating useful fuel economy,
cost, and environmental information
about electric vehicles and several
variations of plug-in hybrid electric
vehicles. As discussed further below,
the research probed consumers to
identify what specific information they
would need if they were to seriously
consider purchasing an advanced
technology vehicle and what
information would be most helpful on
an advanced technology fuel economy
label.160

Phase 2 focus groups were devoted to
exploring what label information
consumers believed was most important
to display for advanced technology
vehicles given the limited space
provided on the fuel economy label. The
focus group discussions were broken
into segments based on three different
vehicle technologies: EVs, extended
range PHEVS, and blended PHEVs.
Focus group discussions thus separated
the different technologies in order to
ascertain more accurately what
information would be most useful to
consumers to understand these new
technologies. Phase 2 focus groups were
tasked with ‘‘building’’ three different
labels, each for different advanced
technology vehicles and were given a
large number of metrics from which to
choose the building blocks. Almost all
of the labels built by each focus group
included the following elements: (1)
The range that the vehicle could travel
while depleting a full battery, the charge
depleting operation; (2) the length of
time it takes to charge the battery; (3)
the cost of charging the battery, and if
operating in two separate fuel modes,
the cost associated with each mode of
operation; and (4) an environmental
metric.161 When asked to identify the
two most important pieces of
information on the label, participants
said, regardless of the city, gender, or
technology discussed, that information
on the range an advanced technology
vehicle can travel on a fully charged
battery and the length of time is takes
to charge the battery were the most
important information they needed to
have in order to seriously consider
purchasing these type of vehicle.
The expert panel’s label
recommendations did not differentiate
between conventional and advanced
technology vehicles. The
recommendations they made for the
conventional vehicle label would apply
to the advanced technology vehicle
label as well.
a. Range
Focus group participants stated that
for any vehicle that operates, even just
part of the time, on electricity, it is
important for them to know the distance
the vehicle can travel on a fully charged
battery. Participants saw this as vital to
their understanding of the vehicle’s fuel
economy. While Phase 2 focus groups
expressed interest in seeing the range
displayed for both city and highway
values, when Phase 3 participants were
presented with full labels, no one asked

for the range to be broken down by city
and highway values.
b. Fuel Cost
Across all advanced technologies,
participants were interested in battery
charging costs. There was a fairly even
split between cost per mile, annual cost
and monthly cost values, regardless of
technology. For any vehicle with a
gasoline-only mode of operation,
participants expressed a desire to see
the cost expressed annually. The groups
also indicated that labels for any vehicle
that operated in a combined gas and
electric mode should provide cost
information on an annual basis. In
Phase 3, when presented with annual
fuel cost and monthly fuel cost options,
many participants used the annual fuel
cost when comparing across advanced
technology vehicles. Some indicated
that the monthly cost was useful for
these advanced technology vehicles. In
particular, people equated the electricity
consumption to their monthly home
electricity statements.

c. Fuel Consumption and Fuel Economy
For any advanced technology vehicle
that operates in a gas-only mode, the
Phase 2 focus groups indicated a strong
desire to see fuel consumption
expressed in miles per gallon. In any
vehicle that had an electric-only mode
of operation, the focus groups favored
seeing the electric consumption
information expressed in an MPG
equivalent of ‘‘MPGs’’. (See Section II.B
for a detailed discussion of MPGe). The
second most understandable metric of
electric-only operation was kilowatthour per 100 miles, but many
participants felt strongly that kilowatt
hours are very unfamiliar and should
not be chosen as a metric. For the
PHEVs with a blended mode (gas and
electric), focus groups were interested in
seeing an MPGe that combined the
MPGe of electric operation and the MPG
of gas operation. In any vehicle that
could operate in more than one mode of
operation, such as an EREV or PHEV,
participants were interested in seeing
fuel consumption values for each mode
of operation, although some were
interested in seeing a consumption
value for the two modes expressed in
MPGe 162 in addition to displaying the
separate consumption information.
d. Environmental Information
Focus group participants did not
independently identify the need to have
environmental information on the label.
162 Participants were given this option using
existing utility factor data as the method for
combing the two modes of operation. See Section
VI.B for a discussion about utility factors.
VerDate Mar<15>2010
18:48 Sep 22, 2010
Jkt 220001
However, in Phase 2, with the exception
of one group, when given the option, all
the groups elected to include
environmental information on the label.
Of the designs provided many
participants selected a horizontal slider
scale that ranked the vehicle’s impact as
the most understandable conveyance of
environmental information.
Other displays of environmental
metrics were examined in Phase 3.
These displays included sliding scales
segmented with relative rating systems
as well as those with absolute values.
Relative ratings such as stars or leaves
were also shown. Participants
commented that they wanted something
that was quick and easy to read. Most
focus group participants preferred
something that was quick with little
detail while some wanted more detailed
information to help inform their
decisions. Based on this finding, the
agencies incorporated this approach
into the co-proposed label designs in
attempt to find the right balance of
simple and detail information
presentation. See section IV.B.1 for
more comprehensive discussion of the
environmental information focus group
findings.
3. Effective Metrics To Enable Vehicle
Comparison
How can consumers compare vehicles
when they are shopping?
Beyond the statutory requirement to
develop rating systems for fuel
economy, GHGs, and other emissions,
with designations of the ‘‘best’’ vehicles
in terms of fuel economy and GHG
emissions, the agencies recognize that
the labels need to be consumer-friendly
in terms of facilitating cross-vehicle and
cross-technology comparisons. If
consumers first encounter advanced
technology vehicles on the dealer’s lot,
and are not predisposed to buy one, a
label that effectively conveys the
benefits of purchasing such a vehicle
through a clear and understandable
rating system will be helpful in
informing consumers and potentially
educating consumers about the benefits
of these vehicles. Through the research
program, the agencies also investigated
how the fuel economy labels might be
designed so that consumers could easily
compare the fuel economy, costs, and
environmental impacts across a range of
vehicle technologies—from
conventional gasoline and diesel
vehicles to electric and plug-in hybrid
vehicles.
Focus groups also provided feedback
about various metrics which were
intended to help a consumer compare a
vehicle to other vehicles, as required by
statute. In Phases 1 and 3, participants
PO 00000
Frm 00060
Fmt 4701
Sfmt 4702
were shown not only rating scales such
as a numerical or five stars system, but
also a slider scale similar to the bar that
exists on the current fuel economy label
for within-class comparisons, both of
which the agencies believed would meet
the statutory requirement to provide a
rating system. The participants seem to
be split into two camps: Those that
prefer the analytical detail of the value
scale, and those that prefer the
simplicity of a star-type rating scale.
For fuel economy and fuel
consumption, Phase 1 participants were
shown two kinds of examples: One that
compared vehicles only within their
current fuel economy class, and one that
showed both a within-class comparison
and a comparison among all vehicles.
These comparisons were shown using
gallons per hundred mile values and
miles per gallon values. The majority of
participants preferred the metric that
showed the subject vehicle as it
compared to all vehicles and as it
compared to its fuel economy class in
units of miles per gallon.
In Phase 2 most focus group
participants said that they would like an
effective way to compare among
disparate vehicle technologies. Many
settled on miles per gallon equivalent as
a comparative metric, but most did not
know what the equivalency was based
upon. In Phase 3, when comparing
advanced technology vehicles, most
participants either used the MPGe value
or the annual cost value to compare
across vehicles. Some used the fuel
economy rating systems that were
provided. In general, the findings from
the focus groups established no clear
preference or approach for how to
effectively communicate comparative
vehicle information that would be
useful to most consumers.
The expert panel disagreed that the
focus group generated labels could be
used effectively to compare across
vehicle technologies— especially to the
level of information found on the
advanced technology labels, which they
described as ‘‘scary’’ and ‘‘unfriendly.’’
They were clear to point out, however,
that their issues were with the label
design, and that they were not rejecting
the information contained on the label.
The expert panel stated that there are
inherent differences in reviewing labels
in a focus group compared to on a
dealership lot, where you have, on
average, very short viewing time. The
expert panel suggested that processing
this amount of information quickly
would be challenging, which could lead
many consumers to tune out the label
completely. As mentioned above, the
panel recommended that the agencies
roll up fuel economy, environmental
E:\FR\FM\23SEP3.SGM
23SEP3
Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
mstockstill on DSKH9S0YB1PROD with PROPOSALS3
impacts and cost information into a
single easily understood letter/grade
approach that will be intuitive for most
consumers. The grade could be used
across all technologies providing
consumers easy comparative
information. The expert panel allowed
that the more complicated information
could be made available in the bottom
half of the label but argued that it would
be crucial to retain a simple compelling
comparison in the top portion of the
label. The panel also suggested
including a comparative metric that
shows the potential savings from buying
a more fuel efficient vehicle, as saving
money historically has been a very
strong motivator for consumers.
4. Effective Whole Label Designs
How should the new labels be
designed to meet the statutory
requirements while best raising
consumers’ understanding of fuel
efficiency, fuel cost and environmental
impact?
In addition to the examination of
individual label elements described
above, consumer research designed by
EPA and NHTSA investigated the effects
of various whole label designs on
consumer comprehension and
utilization, in order to test whether the
labels would still be useful when all of
the elements were put together. This
inquiry is important because there is
only so much space that information
can occupy both on the label and in the
consumer’s mind when standing on the
dealer’s lot and confronted with so
much other information. In order to
provide sufficient information while
ensuring that it remains understandable
for the greatest number of consumers, a
balancing act is inevitable. The
consumer research attempted to assess
how best the balance could be struck, as
discussed further below in Section III.
The expert panel offered very strong
opinions on what, given their
experience, would make a label effective
in engaging the public. They strongly
recommended that the top portion of the
label contain only one element—a
‘‘grade’’ that would combine as many of
our required metrics as possible. This
information should be big, bold, and
easy to process while walking around a
dealership. The label space under the
grade would be reserved for the specific
information required in the statute or
deemed important in focus groups and
other market research. When the panel
was presented with label designs that
had multiple metrics, explanatory text,
and graphical icons, with no one
element standing out, they felt that the
labels were confusing and intimidating.
The expert panel’s consensus view, after
VerDate Mar<15>2010
18:48 Sep 22, 2010
Jkt 220001
viewing the draft labels developed
through the focus groups, was that these
labels would be daunting for most
consumers to process, making them
inclined to ‘‘tune out’’ even the most
basic information. Their strongest
recommendation: Keep it simple.163
5. Tools Beyond the Label
What purchase process do consumers
currently use to make new vehicle
purchasing decisions? Given this
process, when are the most effective
opportunities to communicate fuel
economy and environmental
information?
a. Vehicle Purchase Process
The vehicle purchase process is
complex and iterative. There may be
many opportunities to inform
consumers about the fuel economy and
environmental impact of the vehicles
they are considering. Although much of
this proposal focuses on the actual fuel
economy label, the agencies recognize
that consumers seek out fuel economy
and environmental information at other
times in the purchase process beyond
simply viewing the fuel economy label
on vehicles during visits to dealerships.
In order to determine the most effective
means to provide fuel economy and
environmental information to
consumers, the agencies sought to better
understand when and how consumers
encounter or search for this type of
information in their vehicle purchase
decision-making process.
Information on this vehicle buying
process was obtained in an on-line
survey of focus group participants prior
to the actual focus groups. In addition,
at the start of each session, participants
were asked to discuss their purchase
process so we could better understand
the nuances associated with the
responses we had received through the
on-line survey. The pre-group online
survey indicated that a majority of
respondents already had a vehicle type
in mind when they began the process.
Consumers appear to narrow the
spectrum from all available vehicles to
the vehicle type or types they will
research depending on their specific
needs and interests. In general, the focus
groups used broad categories to describe
vehicle groupings, such as SUVs,
minivans, sport cars, trucks, economy
cars, and midsize cars.164 For example,
some focus group respondents said they
163 Environmental Protection Agency Fuel
Economy Label: Expert Panel Report, EPA420–R–
10–908, August 2010, p. 15–17.
164 These categories are not necessarily related to
the current 14 EPA-designated classes of vehicles.

08.

58137
narrowed their search based on vehicle
cargo space, for others it was sedans,
and for others it was SUVs and
minivans.
According to the pre-focus group
online survey and the focus groups
themselves, a majority of the
participants indicated that price/
affordability was one of the top five
factors that influenced their vehicle
choice. Other key factors that influenced
participants’ vehicle choice included
gas mileage/fuel economy, safety,
reliability, size, interior and exterior
appearance, comfort, brand name and
performance. The agencies also
reviewed existing literature on the
factors that influence vehicle choice.
For example, a 2009 survey of people
between the ages of 18 and 30
(‘‘Generation Y’’) found gas mileage to be
the top factor indicated by participants
as critical to vehicle purchasing
decisions, followed by affordability/
price.165 Both demographic and
psychographic factors (e.g., ‘what a
vehicle says about me’) also play a role
in the vehicle purchase process.166
At present however, environmental
impacts are not top purchasing
considerations for most consumers.
Focus group participants indicated that
environmental impacts were not a
consideration in the type of the vehicle
they purchase. Only a small fraction of
the participants in the pre-group online
survey considered ‘‘low emissions’’ to be
key factor when making a vehicle
purchase decision. This finding is also
supported by the literature review.
Consumer research indicates that
although consumers have a growing
interest in purchasing ‘‘greener’’
vehicles, environmental impact is not
sufficient by itself for most consumers
to be willing to pay a premium.167
Another important aspect of the
vehicle purchase process is how
consumers research vehicles. Twothirds of the respondents to the prefocus group online survey reported they
had researched fuel economy prior to
buying their vehicle. Based on the
available choices in the pre-focus group
survey, respondents reported gathering
fuel economy information from
manufacturer Web sites, Consumer
Reports, auto dealers, vehicle search
websites, automobile magazines, others

with similar vehicles, government
websites, television advertisements, and
the Fuel Economy label itself. The
literature review found that consumers
increasingly research fuel economy
information online. For example, traffic
on the DOE and EPA Web site https://
www.fueleconomy.gov increased from
400,000 user sessions in 1999 to more
than 30 million in 2008.168 Other
Internet sources used to research
vehicles during the purchase process
include consumer-to-consumer tools
such as blogs and Web forums.169
Another finding from the literature
review is that consumers are likely to be
closer to purchasing a vehicle by the
time they visit the dealership than they
were in the past.170 This highlights the
value of educational tools beyond the
label to provide consumers with
information on a vehicle’s fuel economy
and environmental impact. Online tools
may be particularly important. In
addition to the Internet being a source
of information for consumers, online
sales of cars have been steadily
increasing in the U.S. in recent years
(although they still represent a small
percentage of total car sales).171

b. Consumer Education
As described above, the vehicle
purchase decision is not based entirely
on the fuel economy label information,
but is complex and iterative, and
messages presented in contexts beyond
the label may be even more helpful in
getting consumers the information they
need about fuel economy, fuel cost,
GHGs, and other emissions. Several
resources maintained by EPA and DOE
are already available to help consumers
obtain information about comparative
vehicle fuel economy and
environmental information, including

available, under EISA, Congress requires
NHTSA, in consultation with EPA and
DOE, to develop a consumer education
program to improve consumer
understanding of automobile
performance with regard to fuel
economy, greenhouse gas and other
emissions.
While this campaign is still in its very
early stages and is not the subject of this
rulemaking, it will be investigating
modifications to existing tools, new
collaborations for information
dissemination and, potentially, new
forms of media utilization in
communicating the relationship of
automobile performance to fuel
economy and emissions. Particularly
given the changes to the label that we
anticipate will result from this
rulemaking, introducing consumers to
the new information available to them
and how it can be used as they consider
their next vehicle purchase will be very
important.
Since the vehicle purchase process is
multifaceted, EPA and NHTSA would
like to better understand how various
information tools beyond the label can
provide critical fuel economy
information to consumers. EPA and
NHTSA especially seek to understand
what additional types of consumer
information and tools are most
important and what level of
individualized information is needed by
consumers in the future.
There are a variety of existing
education campaigns and resources to
help enable consumers to make more
fuel efficient and environmentally
friendly transportation choices. These
include the Federal Highway
Administration’s initiative ‘‘It All Adds
Up to Cleaner Air,’’ 175 the ‘‘Cleaner Cars
for Maine’’ 176 program, and the ‘‘Drive
Smarter Challenge’’ campaign.177 Brief
descriptions of these and other
education campaigns are available in
the literature review report.178 Such
campaigns may inform the agencies’
development of educational tools to
help consumers make more informed
vehicle purchasing decisions.
The agencies request comment on
ideas for the most effective means to
educate consumers about the new
elements and metrics being proposed on
the label. In addition, EPA and NHTSA
request specific comment on what

additional tools we could provide to
increase consumer comprehension
about complex advanced technology
vehicles and automobile performance
related to fuel economy and emissions.
We are proposing that this campaign
potentially include both traditional
marketing mechanisms, such as
brochures, public service
advertisements, media placements, and
dealership-distributed checklists, along
with more innovative approaches,
which may include crowdsourcing with
social media, interactive web site
displays at dealerships that would allow
consumers to ‘‘personalize’’ their fuel
economy label, smartphone
applications. In addition, per the
recommendation of the expert panel, we
are proposing to develop a Web site that
would be launched in conjunction with
the new label. This consumer-focused,
user friendly Web site would provide
more specific information on the label,
along with access to the tools,
applications, social media, and
materials mentioned above.
All messages and materials will be
tailored according to the method of
communication and the target audience.
EPA is requesting comment on effective
messaging, materials, and methods of
communication.
V. Implementation of the New Label
A. Timing
As previously noted, the agencies are
proposing that the new label
requirements initially take effect with
the 2012 model year. This regulatory
action is scheduled to be finalized in
late December of 2010 or January of
2011 with a final rule effective 30 days
after publication. This timing is similar
to what was provided in the 2006 label
rule.179
Model year 2012 vehicles can be
introduced as early as January 2011, and
in fact EPA has already heard from at
least one manufacturer that plans such
an early introduction, Given that this
regulatory action is not scheduled to be
finalized until December of 2010 or
January of 2011 and that it is possible,
based on when the final rule is
published in the Federal Register for
the effective date of the new regulations
to be a date in March of 2011 it is clear
that not all 2012 model year vehicles
can be captured by the proposed
regulations. There may also be cases
where a manufacturer prints label
‘‘blanks’’ early in the model year, even
if they plan to introduce vehicles in the
more typical time frame of late summer
and early fall. Although the proposed

Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
mstockstill on DSKH9S0YB1PROD with PROPOSALS3
regulations do not presume anything
regarding the date of finalization of the
new label and only specify applicability
to the 2012 model year, we expect that
the final rule will have to take these
issues into account.
The final rule will likely specify a
date of applicability of the new
regulations that is some date certain
after publication of the final rule that
would allow manufacturers adequate
time to plan for and implement the new
designs. We believe that a date on the
order of 30 days after publication would
be appropriate, where vehicles
produced after that date would have to
use the new label format. We would of
course encourage the voluntary use of
the new label to the greatest extent
possible from the date of signature to
the specified effective date. The
agencies request comments on the
appropriate timeframe for implementing
these new label requirements.
The agencies recognize that some of
the potential changes in label design,
including color graphics that would be
printed at production run-time and
differing footprints that necessitate
redesign of the overall Monroney label
may impact the amount of lead time
required by manufacturers. While we
believe that it is extremely important for
the final label changes to take effect as
soon as possible, we seek comment on
these specific potential lead time issues.
To introduce the new label and
ensure that the public understands the
new information and format, the
agencies plan to conduct extensive
public outreach concurrent with the
implementation of a final rule. We will
provide information about the new label
and how to use it via web-based
information, fact sheets, and other
communication methods. This
information will be designed to explain
all aspects of the new label.
B. Labels for 2011 Model Year
Advanced Technology Vehicles
The new fuel economy label will
address advanced technology vehicles,
such as EVs and PHEVs, which some
manufacturers are planning to introduce
into the U.S. market prior to the 2012
model year. EPA issued regulations in
2009 that provided EPA discretion to
authorize appropriate changes to the
current fuel economy label with
individual manufacturers, specifically
with respect to advanced technology.180
These regulations are applicable until
this rule is finalized.
To address labels for advanced
technology vehicles introduced before
this rule is finalized; EPA may allow

any manufacturer of such vehicles that
will be introduced prior to the 2012
model year to use one of the coproposed labels, or an alternative label
that meets EPA’s approval. For example,
EPA could evaluate whether a
manufacturer could use a table that
compares various metrics (e.g., fuel
economy (mpg), electricity consumed
(kWh), miles per gallon equivalent
(mpg-e), and total energy cost) for
different mileages the vehicle is driven
between a full charge of the battery.
This approach would provide the most
complete amount of information for the
vehicle’s performance as a function of
distance travelled. The broad range of
metrics could also make it easier for the
consumer to understand the energy
consumption of the vehicle. The down
side to including a table is that it
provides a lot of information and could
be potentially confusing for some
consumers.
Manufacturers intending to introduce
an advanced technology vehicle as a
2011 model year vehicle should meet
with EPA to discuss the details of actual
implementation. For example, EPA
would discuss with the manufacturer
the fact that the label format and
information may only be used for the
2011 model year and may change for
2012 depending on the outcome of the
final label regulations. EPA would also
discuss in conjunction with the Federal
Trade Commission (FTC) what aspects
of the label information could be
advertised and would also discuss with
the manufacturer the details of specific
test values used, such as mile per gallon
equivalent, kW-hr per 100 miles,
blended mode operation for a PHEV,
etc.
C. Implementation of Label Content
Although much of the information
presented on the label is determined
from test data specific to the labeled
vehicle or can be codified in the
regulations, there are elements that will
require annual (or in some cases,
possibly less frequent) information
provided by EPA. This is no different
from today’s label and the annual
guidance letter published by EPA that
includes the fuel economy ranges for
each class of automobile, the fuel price
information to be used to calculate
costs, and other relevant information.
This information will have to continue
to be provided by EPA on an annual
basis, but the new ratings proposed for
the new labels will also require that
EPA provide annually the range of fuel
economy of all vehicles as well as the
range of CO2 emissions of all vehicles.

VI. Additional Related EPA Proposals
A. Electric and Plug-In Hybrid Electric
Vehicle Test Procedures
1. Electric Vehicles
There currently is no federal test
procedure for measuring fuel economy
for electric vehicles. EPA has
periodically performed fuel economy
testing for electric vehicles utilizing test
procedures and protocols developed by
the Society of Automotive Engineers
(SAE), specifically J1634. Manufacturers
may continue to use SAEJ1634 test
protocols, as cancelled in October 2002
until EPA can comment on a reissued
SAE1634 that is in draft, with the
exception of not using the C coefficient
adjustment in paragraph 4.4.2. The C
coefficient adjustment was intended to
reflect air conditioning loads. Air
conditioning usage is not considered in
´
CAFE testing and is accounted for via
the 5-cycle or derived 5-cycle equations
for labeling. Until recently, there have
been very few electric vehicles sold in
the U.S. market. The few exceptions,
such as the EV1 from General Motors
(GM), were only made available to a
select few customers for a limited time.
As such, there was not a pressing need
for an electric vehicle test procedure.
However, with the imminent release of
several new battery electric vehicles
from manufacturers such as Ford and
Nissan, the need for a Federal test
procedure for measuring fuel economy
or fuel consumption for electric vehicles
is apparent.
Fuel economy estimates are measured
for ‘‘city’’ and ‘‘highway’’ operation. Prior
to the 2008 model year, all vehicles
were fuel economy tested over just two
test cycles: The Federal Test Procedure
(FTP or ‘‘city’’ test) and the Highway
Fuel Economy Test (HFET or ‘‘highway’’
test). In December, 2006, EPA published
revisions to improve the calculation of
fuel economy estimates to better reflect
real world fuel economy
performance.181 These revisions
included three additional chassis
dynamometer test cycles to the current
FTP and HFET for fuel economy testing
purposes. The three additional cycles
were the US06, SC03, and the Cold
Temperature FTP. Prior to the 2008
model year, all three test cycles were
used for emissions purposes for either
the Supplemental Federal Test
Procedure (SFTP) emissions standards
(US06 and SC03) or the cold
temperature (20 °F) emission standards.
Beginning in the 2008 model year, all
vehicles tested for fuel economy
labeling purposes had to use the new ‘‘5181 71

cycle’’ fuel economy methodology
which either required testing all
vehicles over the five test cycles
discussed above or apply an equivalent
5-cycle correction referred to as the
derived MPG- based approach. For
alternative fueled vehicles, including
electric vehicles, manufacturers have
the option for fuel economy testing to
test their vehicle over all five test cycles
or use a derived MPG-based approach
a. FTP or ‘‘City’’ Test
The procedure for testing and
measuring fuel economy and vehicle
driving range for electric vehicles is
similar to the process used by the
average consumer to calculate the fuel
economy of their personal vehicle. The
distance the vehicle can operate until
the battery is discharged to the point
where it can no longer provide
sufficient propulsive energy to maintain
the speed tolerances as expressed in 40
CFR 86.115–78 is measured and divided
by the total amount of electrical energy
necessary to fully recharge the battery,
similar to refueling the gas tank of a
gasoline powered vehicle.
The first step of the procedure is to
determine the distance the vehicle
operates before the battery becomes
discharged to the point where the
vehicle can no longer provide sufficient
propulsive energy to maintain the speed
tolerances as expressed in 40 CFR
86.115–78. This begins with the
preconditioning of the vehicle. The
electric vehicle is preconditioned per 40
CFR part 86, section 132. Following
preconditioning, the Rechargeable
Energy Storage System (RESS) will be
brought to full charge. The RESS will
remain plugged into the electrical
source for a minimum of 12 hours. For
the FTP or city test cycles, the chassis
dynamometer procedures will be
conducted pursuant to 40 CFR 86.135
with the exception that the vehicle will
run consecutive test cycles until the
vehicle is unable to maintain the FTP
speed tolerances as expressed in 40 CFR
86.115–78. To clarify, an FTP
historically consisted of two Urban
Dynamometer Driving Schedules. The
FTP was later shortened to one full
UDDS and only the first bag or phase of
the second UDDS. The second phase of
the second UDDS was considered just a
repeat of the second phase of the first
UDDS. In the context of electric
vehicles, an FTP is two full consecutive
UDDS’s. The second UDDS of any FTP
cycle will be started 10 minutes after the
cold start as per § 86.135. Subsequent
FTP cycles may require up to 30
minutes between starts due to test
facility limitations. Between starts, the
RESS is not to be charged. During the
VerDate Mar<15>2010
18:48 Sep 22, 2010
Jkt 220001
10 minute or other longer soaks, the
vehicle should have the hood closed
and the cooling fans shut off.
If an electric vehicle cannot reach the
FTP top speed, then the test will
terminate once the vehicle speeds
cannot be maintained within 2 mph as
described in 40 CFR 86.115–78 up to the
maximum speed. For low powered
electric vehicles that cannot reach the
FTP top speed, the vehicle top speed is
the maximum speed the vehicle reached
during the first FTP. The Administrator
may approve alternate end of test
criteria. For low powered electric
vehicles that by design cannot maintain
the speed tolerances as expressed in 40
CFR 86.115–78, low powered vehicles,
the vehicle will continue testing if the
vehicle is operated at maximum power.
This provision is intended to apply
uniformly throughout all the
consecutive FTP cycles. A vehicle that
can maintain trace speed on the first
FTP cannot then be declared a low
powered vehicle for subsequent FTP
cycles. Upon reaching the end of test
criteria, the distance driven shall be
recorded and the vehicle decelerated to
a stop. The end of test criteria is when
the vehicle can no longer maintain the
drive cycle per 40 CFR 86.115–78 or, for
a low powered EV, can no longer
maintain the speed tolerances per 40
CFR 86.115–78 up to the vehicle
maximum speed as defined above.
Similarly, low powered vehicles that
cannot maintain the drive cycle due to
insufficient acceleration will use the
trace driven on first UDDS as the
tolerance for end of test.
The final stage of the electric vehicle
test procedure is the measurement of the
electrical energy used to operate the
vehicle. The end of test recharging
procedure is intended to return the
RESS to the full charge equivalent of the
pre test conditions. The recharging
procedure must start within three hours
after completing the EV testing. The
vehicle will remain on charge for a
minimum of 12 hours to a maximum of
36 hours. After reaching full charge and
the minimum soak time of 12 hours has
been reached, the manufacturer may
physically disconnect the RESS from
the grid. The alternating current (AC)
watt-hours must be recorded throughout
the charge time. It is important that the
vehicle soak conditions must not be
violated. The measured AC watt-hours
must include the efficiency of the
charger system. The measured AC watt
hours are intended to reflect all
applicable electricity consumption
including charger losses, battery and
vehicle conditioning during the
recharge and soak, and the electricity
consumption during the drive cycles.

Frm 00064
Fmt 4701
Sfmt 4702
Finally, the raw electricity consumption
is calculated by dividing the recharge
AC watt-hours by the distance traveled
before the end of the test criteria is
reached.
b. HFET or ‘‘Highway’’ Test
Similar to the FTP test procedure, the
first step of the procedure is to
determine the distance the vehicle
operates before the battery becomes
fully discharged. This begins with the
preconditioning of the vehicle. Vehicle
preconditioning is to be conducted as
per 40 CFR part 86, section 132.
Following preconditioning, the RESS
will be brought to full charge. The RESS
will remain plugged into the electrical
source for a minimum of 12 hours. The
vehicle may remain plugged into the
electrical source up to 36 hours.
Dynamometer procedures will be
conducted pursuant to 40 CFR 600.111
with the exceptions that electric
vehicles will run consecutive cycles of
the HFET until the end of test criteria
is reached. Subsequent HFET cycle
pairs may require up to 30 minutes of
soak time between HFET cycle pairs due
to facility limitations. Between cycle
pairs, the vehicle hood is to be closed
and the cooling fans shut off. Between
starts, the RESS is not to be charged.
If an electric vehicle cannot reach the
HFET top speed, then the test will
terminate once the vehicle speeds
cannot be maintained, up to the
maximum speed. For low powered
electric vehicles that cannot reach the
HFET top speed, the vehicle top speed
is the maximum speed the vehicle
reached during the first HFET. The
Administrator may approve alternate
end of test criteria. For low powered
electric vehicles that by design cannot
maintain the speed tolerances as
expressed in 40 CFR 86.115–78, the
vehicle will continue testing if the
vehicle is operated at maximum power.
This provision is intended to apply
uniformly throughout all the
consecutive HFET cycles. Similarly, low
powered vehicles that cannot maintain
the drive cycle due to insufficient
acceleration will use the trace driven on
first UDDS as the tolerance for end of
test. A vehicle that can maintain trace
speed on the first HFET cannot then be
declared a low powered vehicle for
proceeding HFET cycles.
Similar to the FTP test procedure, the
final stage of the HFET test procedure is
the measurement of the electrical energy
used to operate the vehicle. The end of
test recharging procedure is intended to
return the RESS to the full charge
equivalent of the pre test conditions.
The recharging procedure must start
within three hours after completing the
E:\FR\FM\23SEP3.SGM
23SEP3
Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
EV testing. The vehicle will remain on
charge for a minimum of 12 hours to a
maximum of 36 hours. After reaching
full charge and the minimum soak time
of 12 hours has been reached, the
manufacturer may physically
disconnect the RESS from the grid. The
alternating current (AC) watt-hours
must be recorded throughout the charge
time. It is important that the vehicle
soak conditions must not be violated.
The measured AC watt-hours must
include the efficiency of the charger
system. The measured AC watt hours
are intended to reflect all applicable
electricity consumption including
charger losses, battery and vehicle
conditioning during the recharge and
soak, and the electricity consumption
during the drive cycles. Finally, the raw
electricity consumption is calculated by
dividing the recharge AC watt-hours by
the distance traveled before the end of
the test criteria is reached.
c. Other EV Test Procedures
The Administrator may approve or
require equivalent or additional EV test
procedures including incorporating via
reference SAEJ1634 published after this
notice.
2. Plug-in Hybrid Electric Vehicles
mstockstill on DSKH9S0YB1PROD with PROPOSALS3
a. PHEV Test Procedure Rationale
Test procedures for plug-in hybrid
electric vehicles (PHEV) are required to
quantify some operation unique to plugin hybrids. The intent in developing
new PHEV test procedures is to use
existing test cycles and test procedures
where applicable. PHEV operation can
be generally classified into two modes
of operation, charge depleting and
charge sustaining operation. Charge
depleting operation can be described as
vehicle operation where the
rechargeable energy storage system
(RESS), commonly batteries, is being
depleted of its ‘‘wall’’ charge. Charge
sustaining operation can best be
described as conventional hybrid
operation.
New procedures for charge depleting
operation would consist of existing test
cycles repeated until the PHEV RESS is
depleted to charge sustaining operation.
Whereas in the past a conventional
vehicle would be expected to consume
fuel and emit emissions over repetitive
identical test cycles consistently, the
same cannot be said of PHEVs. PHEV
fuel consumption, fuel mix, and
emissions may change as the RESS is
depleted. In order to accurately assess
the emissions and fuel efficiency of a
PHEV, the PHEV requires testing over
the entire charge depleting range.
Testing over the entire charge depleting
VerDate Mar<15>2010
18:48 Sep 22, 2010
Jkt 220001
range requires new test provisions to
address vehicle setup and prep,
measuring and charging the RESS,
operation over repetitive test cycles, and
calculating any new values that are now
measured over repetitive test cycle.
As described above, charge sustaining
operation can best be described as
conventional hybrid operation. EPA
would continue to use existing hybrid
electric vehicle test procedures. The
primary differences between HEV and
other conventional vehicle testing are
the need to monitor RESS state of charge
and the extra drive time required to
insure vehicle warm operation during
the Federal Test Procedure. The RESS is
measured and subject to the state of
charge tolerances, below, to insure all
energy is accurately accounted. The
fully warm operation is satisfied by
running a full 4 phase Ftp instead of the
abbreviated 3 phase Ftp as traditionally
used for conventional vehicle testing.
For the purposes of fuel economy
label testing, PHEVs would be subject to
the same test cycles as other light duty
vehicles with a few exceptions. While
operating in charge depleting mode, a
PHEV is using electricity originally from
an off board source. This is to say that
a PHEV is operating at least partially on
an alternative fuel while operating in
charge depleting mode. For the
purposes of fuel economy, PHEVs could
continue to use the derived 5-cycle
adjustment while in charge depleting
mode. The derived 5-cycle adjustment
would be applied to the total city and
total highway fuel economies
separately. For the purposes of applying
the 5-cycle correction, the total fuel
economies in charge depleting mode
include both of the fuels consumed,
typically gas and electricity, as
expressed in a miles per gallon of
gasoline equivalent unit. The 5-cycle
correction is to be applied to the
combined energy of each mode of
operation even if the energy
consumption is ultimately fuel specific.
Applying a correction to the gasoline
and electricity consumption separately
could lead to a smaller adjustment than
other vehicles since the 5-cycle
correction is not linear. While in charge
sustain mode, PHEVs would be subject
to the same test procedures as
conventional hybrid electric vehicles.
PHEVs must meet all applicable
emissions standards regardless of RESS
state of charge. EPA will consider a
RESS as an adjustable parameter for the
sake of emissions testing. It is the
manufacturer’s responsibility to insure
vehicles are emissions compliant. EPA
typically allows good engineering
judgment in applying worse case
emission testing criteria. For the
PO 00000
Frm 00065
Fmt 4701
Sfmt 4702
58141
purposes of certification compliance,
EPA will consider charge sustain
operation as worse case. EPA may
confirmatory test or request the
manufacturer to provide test data for
any test cycle at any state of charge.
Evaluation of fuel economy testing
emissions may be used to change worse
case emissions assumptions.
b. PHEV Test Procedure and
Calculations
The EPA proposes to incorporate by
reference SAEJ1711, in part, for PHEV
test procedures.
Charge Depleting Operation—FTP or
‘‘City’’ Test and HFET or ‘‘Highway’’ Test
The EPA proposes to incorporate by
reference SAEJ1711 chapters 3 and 4 for
definitions and test procedures,
respectively, where appropriate, with
the following exceptions and
clarifications. UF weighting is not
intended for use with criteria pollutants.
Test cycles will continue until the
end of the phase in which charge
sustain operation is confirmed. Charge
sustain operation is confirmed when
one or more phases or cycles satisfy the
Net Energy Change requirements below.
EPA seeks comment on manufacturers
optionally terminating charge deplete
testing before charge sustain operation
is confirmed with state of charge
provided that the RESS has a higher
SOC at charge deplete testing
termination than in charge sustain
operation. In the case of Plug In Hybrid
Electric Vehicles with an all electric
range, engine start time will be recorded
but the test does not necessarily
terminate with engine start. PHEVs with
all electric operation follow the same
test termination criteria as blended
mode PHEVs. Testing can only be
terminated at the end of a test cycle. The
Administrator may approve alternate
end of test criteria.
For the purposes of charge depleting
CO2 and fuel economy testing,
manufacturers may elect to report one
measurement per phase (one bag per
UDDS). Exhaust emissions need not be
reported or measured in phases the
engine does not operate.
End of test recharging procedure is
intended to return the RESS to a full
charge equivalent to pre test conditions.
The recharge AC watt hours must be
recorded throughout the charge time.
Vehicle soak conditions must not be
violated. The AC watt hours must
include the charger efficiency. The
measured AC watt hours are intended to
reflect all applicable electricity
consumption including charger losses,
battery and vehicle conditioning during
the recharge and soak, and the
E:\FR\FM\23SEP3.SGM

58142
Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
electricity consumption during the drive
cycles.
Net Energy Change Tolerance, NEC, is
to be applied to the RESS to confirm
charge sustaining operation. The EPA is
proposing to adopt the 1% of fuel
energy NEC state of charge criteria as
expressed in SAEJ1711. The
Administrator may approve alternate
NEC tolerances and state of charge
correction factors if the 1% criteria is
insufficient or inappropriate.
Preconditioning special procedures
are optional for traditional ‘‘warm’’ test
cycles that are now required to test
starting at full RESS charge due to
charge depleting range testing. If the
vehicle is equipped with a charge
sustain switch, the preconditioning
cycle may be conducted per 600.111
provided that the RESS is not charged.
Exhaust emissions are not taken in
preconditioning drives. Alternate
vehicle warm up strategies may be
approved by the Administrator. This
will allow a method for starting ‘‘warm’’
test cycles with a fully charged battery.

definitions and test procedures. The
EPA proposes to adopt the 1% of fuel

provided that the RESS is not charged.
Exhaust emissions are not taken in
preconditioning drives. Alternate
vehicle warm up strategies may be

Charge Depleting Range Determination
Actual Charge Depleting Range (RCDA)
will be a calculated value that uses the
charge sustaining state of charge of the
RESS to define the RCDA endpoint. Due
to the nature of PHEVs, RCDA will
require calculation and is not
necessarily when the engine first starts.
Defining RCDA using only engine on
could leave PHEVs with three modes of
operation. These three modes would be
charge depletion, charge regeneration,
and charge sustaining. If the
regeneration of the RESS from the
VerDate Mar<15>2010
18:48 Sep 22, 2010
Jkt 220001
engine is not accounted for in the charge
depleting mode, the RESS could be deep
cycled beyond the CS SOC to gain range
while the increase in CO2 emissions due
to the RESS regeneration would not be
captured in the charge sustaining
testing.
Calculation of RCDA will require
monitoring the RESS SOC throughout
charge depleting testing. The RCDA for
each cycle would be the driven cycle
distance from start of CD testing until
the charge sustaining SOC is ‘‘crossed’’.
The EPA is proposing to incorporate by
reference the SAEJ1711 calculation for
Actual Charge Depleting Range.
c. Other Test Cycles
PHEV and Electric vehicle testing
over the SC03, US06, or Cold CO test
cycles would follow the same general
procedure as the FTP and HFED. EPA
would consider the use of alternate or
equivalent PHEV test procedures and
may incorporate by reference SAEJ1711.
d. Test Tolerances
State of Charge tolerance correction
factors may be approved by the
Administrator. RESS state of charge
tolerances beyond the 1% of fuel energy
may be approved by the Administrator.
e. Mileage and Service Accumulation
The EPA is seeking comment on
modifying the minimum and maximum
allowable test vehicle accumulated
mileage for both EVs and PHEVs. Due to
the nature of PHEV and EV operation,
testing may require many more vehicle
miles than conventional vehicles.
Furthermore, EVs and PHEVs either do
not have engines or may use the engine
for only a fraction of the miles driven.
f. Test Fuels
Electric Vehicles and PHEVs are to be
recharged using the supplied
manufacturer method provided that the
methods are available to consumers.
This method could include the
electricity service requirements such as
service amperage, voltage, and phase.
Manufacturers may employ the use of
voltage regulators in order to reduce test
to test variability with prior
Administrator approval.
B. Utility Factors
1. Utility Factor Background
Utility Factors are a method of
combining CO2 emissions, fuel
consumption, or other metrics from
multiple modes of operation into one
value. The extent to which utility
factors are used on a fuel economy label
is completely dependent upon label
format. That is to say, some PHEV label
formats may not require utility factors at
PO 00000
Frm 00066
Fmt 4701
Sfmt 4702
all or possibly only for CO2. This
discussion on utility factor is required
to understand the different PHEV label
formats within this proposal.
As discussed previously, PHEVs can
use two types of energy sources: (1) An
onboard battery charged by plugging the
vehicle into the electrical grid possibly
via a conventional wall outlet to power
an electric motor, as well as (2) a gas or
diesel-powered engine to propel the
vehicle or power a generator used to
provide electricity to the electric motor.
Depending on how these vehicles are
operated, they can use electricity
exclusively, never use electricity and
operate like a conventional hybrid, or
operate in some combination of these
two modes. This can make it difficult to
estimate fuel economy, fuel
consumption, annual cost, or CO2
emissions from these vehicles.
The EPA has worked closely with
stakeholders including vehicle
manufacturers, the Society of
Automotive Engineers (SAE), the State
of California, the Department of Energy
(DOE), and others to develop an
approach for estimating fuel economy,
fuel consumption, cost, CO2 emission,
or any other metric for vehicles that can
operate using more than one energy
source. EPA believes the appropriate
method for combining the operation of
vehicles that can operate with more
than one fuel would be a weighted
average of the appropriate metric for the
two modes of operation. A methodology
developed by SAE and DOE to predict
the fractions of total distance driven in
each mode of operation (electricity and
gas) uses a term known as a utility factor
(UF). UF’s were developed using data
from the 2001 Department of
Transportation ‘‘National Household
Travel Survey’’. A detailed method of
UF development can be found in the
Society of Automotive Engineers (SAE)
J2841 ‘‘Utility Factor Definitions for
Plug-In Hybrid Electric Vehicles Using
Travel Survey Data’’. At the time of this
proposal, SAEJ2841 was in the process
of balloting prior to publishing. SAE
reference documents can be obtained at
https://www.SAE.org. By using a utility
factor, it is possible to determine a
weighted average of the electric and
gasoline modes. For example, a UF of
0.8 would indicate that an all-electric
capable PHEV operates in an all electric
mode 80% of the time and uses the
engine the other 20% of the time. In this
example, the weighted average fuel
economy value would be influenced
more by the electrical operation than the
engine operation.
For the purposes of PHEVs, UF
development makes several
assumptions. Assumptions include: the
E:\FR\FM\23SEP3.SGM
23SEP3
Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
first mode of operation is always electric
assist or all electric drive, vehicles will
be charged once per day, and that future
PHEV drivers will follow drive patterns
exhibited by the drivers in the surveys
used in SAEJ2841. EPA acknowledges
that current understanding of the above
assumptions and that the data upon
which utility factors were developed
may change. Therefore, EPA may
change the calculation of future utility
factors in light of new data in a future
rulemaking.
2. General Application of Utility Factors
While acknowledging the
assumptions above, a UF could be
assigned to each successive test or phase
of testing until the battery charge was
depleted to the point where the PHEV
sole source of power was from the
gasoline or diesel engine. One minus the
sum of all the utility factors would then
represent the fraction of driving
performed in this ‘‘gasoline or diesel
mode.’’ Carbon dioxide emissions could
then be expressed as:
Equation VI.B.2-1
i
1
(
Ym = ∑ (UFi × Yi ) + 1 − ∑
i
UFi
1
)×Y
CS
Where:
Ym is the Utility Factor averaged mass of
carbon dioxide for a specific drive cycle.
Yi are the CO2 mass emissions or CO2
equivalent mass emissions for each
phase or test cycle. For electricity, a
carbon dioxide equivalent may be used
as determined by the Administrator.
Ycs is the charge sustain carbon dioxide mass
emissions and for hybrids in the case of
the FTP can be expressed as Ycs= 0.43*
Yc + 0.57* YH., where Yc is the charge
sustain cold start test and YH is the
charge sustain hot start mass emissions
of carbon dioxide.
UFi is the driving cycle and sequentially
specific utility factor.
Likewise, the electrical consumption
would be expressed by adding the
electricity consumption from each
mode. Since there is no electrical
consumption in hybrid mode, or charge
sustain mode, the equation for
electricity consumption would be as
follows:
Equation VI.B.2-2
i
Em = ∑1 (UFi × Ei )
Where Em is the utility factor averaged
electricity consumption, Ei is the electricity
consumption proportioned to each
successive drive cycle, and UFi is the driving
cycle and sequentially specific utility factor.
3. Calculating Combined Values Using
Cycle Specific Utility Factors
Utility factors could be cycle specific
not only due to different battery ranges
on different test cycles but also due to
the fact that ‘‘highway’’ type driving may
imply longer trips than urban driving.
This would lead to different utility
58143
factors for urban and highway driving.
The following section explains the EPA
proposal of assigning a utility factor to
each successive phase or test cycle
performed in charge depleting or
‘‘PHEV’’ mode.
Utility factors can be assigned to each
mode of operation according to the
distance driven in each mode for a given
powertrain combination. Rather than
calculating a unique UF for each cycle
based on measured distance driven,
UF’s will be assigned to each successive
phase of consecutive Urban
Dynamometer Driving Schedules, and
each successive Highway Fuel Economy
Driving schedule of consecutive HFEDs.
Composite city and composite highway
CO2 emissions will first be calculated
using test results and UFs from the
respective cycles. Final combined
values will then be an averaged 55%
city and 45% highway value. The
proposed cycle specific utility factors
for UDDS or ‘‘city’’ driving are provided
in Table VI.B.2–1 and the proposed
cycle specific utility factors for HFEDS
or ‘‘highway’’ driving are provided in
Table VI.B.2–2. The method used to
develop cycle specific utility factors can
be found in SAEJ2841. EPA seeks
comment on using utility factors other
than the fleet 55/45 city/highway
specific utility factors for labeling and
compliance. Finally, example CO2
calculations are provided below.

Applying the above data for the

formula in Equation VI.B.2–1 using

(3.62 + 3.85) + 0.57 x (890 + 885)/(3.54
+ 3.88) = 241g CO2 g/mi. The total CO2
g/mi, Ym, excluding any electricity CO2
equivalence would then be 139 g/mi.
To determine electricity consumption
one would apply utility factors in a
similar fashion using equation VI.B.2–2
and Table VI.B.2–1. Em= 195.5 W hr/mi

calculated by summing the two values,
given a CO2 equivalency for electricity.
For example, if the Watt hour CO2
equivalent was 0.26g CO2 per Watt hour,
the total CO2 emissions could then be
expressed as the sum of the CO2 and
CO2-equivalent emissions from both
modes of operation. From the example
above, the overall CO2 emissions would
be 139 gCO2 per mile + (84.4 W hr/mi)
22gCO2equiv per mile = 161g CO2 per
mile.
Utility factors can also be used to
calculate a miles per gallon equivalent
measurement similar to the CO2
example above. Additional assumptions
are required, however, when applying
utility factors to a Corporate Average
Fuel Economy and possibly a fuel
economy labeling miles per gallon of
gasoline equivalent measure.
Previously, when calculating PHEV
CO2 emissions, the CO2 emissions were
part of a manufacturer fleet average. The
same is true of Corporate Average Fuel
Economy. CAFE is a fleet average.

fueled vehicles, both CAFE and CO2
fleet calculations would use the cycle
specific fleet utility factors. For the
purposes of a possible label fuel
economy, a fleet average is not the aim,
but rather what the average driver
would likely experience or expect. For
this reason, the EPA is proposing the
use of the cycle specific Multiday
Individual Utility Factors. The
individual utility factors do not weight
vehicle miles traveled towards the
longer trips like fleet utility factors. For
a detailed explanation on utility factor
development see SAEJ2841.
Similar to determining a total CO2
emissions value for PHEVs, calculating
a miles per gallon total for PHEVs will
require an electricity to gasoline
conversion. This miles per gallon
equivalent of gasoline would be
´
calculated differently for CAFE and
label. For a FE label number, EPA
would use a miles per gallon of gasoline
equivalent energy factor for electricity of
E:\FR\FM\23SEP3.SGM
23SEP3
Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
33,705 watt hours per gallon.182 This
same gasoline equivalency would be
´
used for CAFE calculation, if the PHEV
did not meet the minimum distance
requirements of a dual fueled vehicle.183
In the case of PHEVs with diesel
engines, EPA proposes to similarly
require calculation of a miles per gallon
equivalent for battery operation, but
specifying instead to rely on a
conversion using the energy content of
diesel fuel. We propose to specify an
energy content of 36,700 Watt hours per
gallon of diesel fuel. This is based on
the approximately 9 percent higher
energy density for diesel fuel relative to
gasoline. We request comment on this
approach to calculating fuel economy
values for diesel-fueled hybrid electric
vehicles.
If the PHEV met the dual fuel range
minimums for electricity a Petroleum
Equivalency Factor would be used
instead of the gasoline equivalent
energy factor. For a PHEV without fuel
fired accessories, the PEF would be
82,049 watt hours per gallon of gasoline.
For details on PEF and gasoline
equivalent energy content see 10 CFR
474.3. Using the procedure for
calculating a dual fueled vehicle FE for
´
CAFE the fuel economy of both modes
of operation would be harmonically
averaged 50/50 and a utility factor
would not be necessary.184
4. Low Powered Vehicles
Vehicles using the low powered
vehicle provision in 40 CFR 86.115–

factors for low powered vehicles would

paragraph B.3, except that the utility
factors would be calculated based on
measured distance and not assigned
based on phase or cycle distance.
C. Comparable Class Categories
EPCA requires that the label include
the range of fuel economy of comparable
vehicles of all manufacturers.185 EPA’s
comparable class structure provides a
basis for comparing a vehicle’s fuel
economy to that of other vehicles in its
class.186 The definitions of vehicle
classes were last revised by EPA’s 2006
labeling final rule. That action finalized
two specific changes to the vehicle class
structure. Separate new classes were
added for sport utility vehicles (SUVs)
and minivans (these were previously
included in the Special Purpose Vehicle
category), and the weight limit for Small
Pickup Trucks was increased from 4,500
pounds gross vehicle weight rating
(GVWR) to 6,000 pounds GVWR. These
FR 36990, June 12, 2000.
U.S.C. 32901(c) and 49 CFR 538.5
Minimum Driving Range.
were non-controversial changes that
were generally seen as a move to keep
the class structure as current as possible
given the changing vehicle market. The
resulting structure is one that contains
nine car categories, five truck categories,
and a ‘‘special purpose vehicle’’
category. It should also be noted that the
EPA-defined vehicle classes are used
only to provide consumer information
about fuel economy and serve no other
regulatory purpose.
EPA is proposing one modification to
the class categories. Consistent with the
distinction currently made between
small and large pickup trucks, EPA is
proposing to divide the SUV class into
small and large SUVs. We do not believe
that it is appropriate, for example, to
include a Toyota RAV4 in the same
class as a Toyota Sequoia, or a Ford
Escape in the same class as a Ford
Expedition. The single SUV category
currently described in the regulations
would be replaced by the two following
proposed categories:
• Small sport utility vehicles: Sport
utility vehicles with a gross vehicle
weight rating less than 6,000 pounds.
• Standard sport utility vehicles:
Sport utility vehicles with a gross
vehicle weight rating of 6,000 pounds
up to 10,000 pounds.

class only goes up to 8,500 pounds

GVWR, SUVs between 8,500 and 10,000
pounds GVWR are defined as mediumduty passenger vehicles, and they will
be subject to fuel economy labeling
starting with the 2011 model year. EPA
requests comment on whether this is an
appropriate way to distinguish the SUV
classes.
Although EPA received many
comments on the 2006 rule regarding
the class structure, some of its inherent
problems, and how people may or may
not shop within classes, there were no
specific suggestions on how to revise
the structure to resolve the issues that
were raised. We believe that with the
refinement to the SUV category we are
proposing, the comparable class
structure would generally represent the
physical distinctions between vehicle
types offered in the fleet today.
However, there may be other
distinctions between vehicles not
captured in these categories, such as the
luxury vehicle segment. The DOE/EPA
Web site (https://www.fueleconomy.gov)
incorporates vehicle cost into the sedan
category, for example, dividing sedans
into ‘‘family,’’ ‘‘upscale,’’ and ‘‘luxury.’’
EPA requests comment on incorporating
such an approach into the comparable
class categories, and specifically, how it
might be done given the changing
nature of vehicles and vehicle prices.

D. Using Smartphone QR Codes® To
Link to Fuel Economy Information
mstockstill on DSKH9S0YB1PROD with PROPOSALS3
For all the label designs being
considered, EPA is proposing that
manufacturers place a QR Code on the
label that will link the web browser of
a properly configured smartphone to the
mobile version of the EPA/DOE fuel
economy information Web site, or
alternatively, to the vehicle-specific
information located on the EPA/DOE
Web site.187 (Note that although the
proposed Label 1 design incorporates a
different Web site URL, the intent
would remain the same: to use the QR
Code to directly link the users
Alternatively and preferably, the
manufacturer would use the QR Code
that represents the URL where
information for the specific labeled
vehicle is available. However, this
would depend upon resolving some
specific data issues. For example, the
manufacturer would have to know the
vehicle-specific URL at the time the
label is printed. This could require that
EPA issue more frequent updates to the
web site throughout the year, or that
EPA assign a vehicle identification
parameter early in the process. It may be
the case that even if the vehicle is not
yet included on the DOE/EPA Web site
that a URL, and thus a QR Code, could
be easily assigned or determined. EPA is
confident that we can work with DOE to

smartphone to vehicle-specific
information while providing additional
tools for making vehicle comparisons,
learning more about the vehicle, etc.)
Many focus group participants
expressed excitement and interest in the
prospects of being able to access
information in this way using their
mobile devices, and EPA believes it is
a potentially useful and valuable tool for
consumers.
QR Codes, like other two-dimensional
bar codes, are simply used to store
information. QR Codes were originally
developed for use in tracking parts in
vehicle manufacturing, and are now
being used for other purposes, such as
storing a Web site URL into an encoded
graphic that can be scanned. These
codes—the use of which is growing in
popularity in the U.S.—are twodimensional black and white codes (like
a bar code) that eliminate the need to
type a Web link into a mobile phone (an
action that can be cumbersome and that
many mobile users might prefer
avoiding). Reading a QR Code requires
that scanning software be installed on
the mobile phone. Many smartphone
manufacturers have begun to pre-install
QR Code readers, but for those that do
not, the readers are very easy to
download, and many are available for
free for nearly every type of mobile
device. Once equipped with the correct
scanning application, consumers can
point and scan to instantly connect to
information they actually want, versus
information pushed to them.
For example, scanning the proposed
code would link the phone’s web
browser to the mobile version of the
DOE/EPA Web site. At that point the
user could view additional information
about the efficiency and environmental
impacts of the vehicle, with available
options such as creating customized
estimates based on the user’s personal
driving habits and distances. The user
could also look up other vehicles and
compare those to the vehicle they are
viewing.
EPA is proposing that the
manufacturer place one of two QR
Codes on the fuel economy label. These
QR Codes would be determined based
on an international standard that would
be incorporated by reference in the
regulations.188 The default option
would be to insert the QR Code that
would take the user’s web browser to
the mobile version of the DOE/EPA fuel
economy information Web site. The QR
Code for this site, including the text that
EPA proposes accompanies it, would
look like this:

labeling requirements by placing the
fuel economy information on the label
required by AIDA, a practice that has
been used by most manufacturers. See
49 U.S.C. 32908(b)(2). In fact, EPA
regulations express a specific preference
that manufacturers do this, ‘‘provided
that the prominence and legibility of the
fuel economy label is maintained.’’ See
40 CFR 600.306–08(c).
In the third phase of focus groups we
had participants consider the placement
of the fuel economy on the Monroney
label, and whether participants had a
specific preference for where to locate
the fuel economy information. Although
participants expressed a variety of
opinions, a slight preference emerged
for displaying the fuel economy
E. Fuel Economy Information in the
context of the ‘‘Monroney’’ Sticker
As noted in Section VIII, the
Automobile Information Disclosure Act
(AIDA) requires the affixing of a retail
price sticker to the windshield or side
window of new automobiles indicating
the Manufacturer’s Suggested Retail
Price of the vehicle and other required
vehicle information. AIDA is more
commonly known as the Monroney Act
(Senator Mike Monroney was the chief
sponsor of AIDA) or Price Sticker Act.
See 15 U.S.C. 1231–1233. This sticker is
commonly called the ‘‘Monroney’’ label.
EPCA states that EPA ‘‘may allow’’ a
manufacturer to comply with the EPCA

information in the upper right portion of
the Monroney label.
The agencies recognize that EPCA
does not require that the fuel economy
information be on the Monroney label,
and that there are instances when auto
manufacturers may want to display the
fuel economy information separately
(e.g., if window space is limited on a
small vehicle and/or the Monroney label
size needs to be reduced). EPA does not
intend to preclude the option of placing
the new label in any appropriate and
prominent location on the vehicle.
However, the agencies request comment
on whether we should require that the
fuel economy information be placed in
a specific location on the Monroney
label (such as the upper right corner, or
on the right side) as a condition of
allowing the information to be included
on that label.189 Although consumer
preference for a specific location on the
Monroney was vague, the agencies
believe that consumers would be able to
locate the new label information on the
vehicle more easily if it appeared in a
consistent location within the
Monroney sticker.
The agencies also seek comment
concerning the potential for the new
label information to create confusion
about other information found on the
Monroney Label, in particular, the star
safety ratings. Specifically, the agencies
seek comment on whether consumers
might interpret the large letter grade on
Label 1 as applying to other aspects of
the vehicle’s performance (such as
safety) besides fuel economy and
environmental impacts. To mitigate this
concern, the agencies have created a
prominent black border and title
indicating the purpose of the
information. Nevertheless the agencies
seek comment on whether additional
measures should be required under
32908(b) and (g) to address this
potential confusion.
The agencies also seek comment on
whether the co-proposed labels, in
particular Label 1 with its use of color
and large font for the overall letter
grade, might inadvertently distract
consumers from the black-and-white
star safety ratings. As one way of
addressing this potential issue, NHTSA
proposes to require under 49 CFR
575.301 that the star safety ratings be
located as close as physically possible to

the conditions for placement in the Monroney label

the Monroney label.

the new fuel economy and
environmental label to help ensure that
the star safety ratings do not get ‘‘lost’’
on the Monroney Label. Similarly, the
agencies seek comment on whether their
regulations for the new fuel economy
and environmental label should require
that it be located as close as physically
possible to the star safety ratings.
Another way of addressing this
potential issue is by re-visiting the
minimum size requirements for the
safety rating label and the font of
information on it. In a final rule190
implementing the requirement in the
Safe, Accountable, Flexible, Efficient
Transportation Equity Act: A Legacy for
Users (SAFETEA–LU) for placing safety
rating information on the Monroney
vehicle price label, the agency
interpreted that Act’s specification of a
minimum size for the label as indicating
the agency did not have any discretion
regarding minimum size, instead of
interpreting the specification as merely
establishing a floor on the discretion of
the agency to specify a minimum size.
In comments made in response to a
subsequent proposal191 to place an
overall safety rating on the safety rating
label, the Advocates for Highway and
Auto Safety questioned that
interpretation. In a recent meeting with
Bosch, representatives of that company
also questioned that interpretation. In
light of the issues in this rulemaking
and those questions, the agency is reexamining that interpretation.
F. Miscellaneous Amendments and
Corrections
EPA is also proposing a number of
non-controversial amendments and
corrections to the existing regulations.
First, we are making a number of
corrections to the recently finalized
regulations for controlling automobile
greenhouse gas emissions.192 These
changes include correcting
typographical errors, correcting some
regulatory references, and adding some
simple clarifications.
Second, we are correcting an
oversight from the 2006 labeling rule
regarding the applicability of testing
requirements to independent
commercial importers (ICIs). Currently
several vehicle categories (dedicated
alternative fuel, dual fuel while
operating on alternative fuel, and
MDPVs) are exempted from having to
perform full 5-cycle fuel economy
testing. These categories are allowed to
use the ‘‘derived 5-cycle’’ method,
whereas other vehicles must use data

from all five test cycles at certification
to perform an evaluation that
determines whether the test group can
use the derived 5-cycle method or
whether they must complete full 5-cycle
testing. The reason for exempting these
vehicles is that the evaluation required
at certification requires the use of all 5
cycles as run for emissions certification,
but these categories are not subject to
the SFTP requirements, and thus such
vehicles do not perform two of the five
test procedures (the US06 high speed/
acceleration test and the SC03 air
conditioning test). Thus when EPA
finalized the 2006 label rule we
recognized that these categories would
not have the data required to perform
the certification evaluation, and we
decided to exempt them from five cycle
testing. However, this same exemption
should have been applied to ICIs. Like
the vehicle categories noted above,
vehicles imported by ICIs are not
required to perform the SFTP emission
tests, and thus also won’t have the
necessary data to perform the 5-cycle
certification evaluation. Therefore, we
are proposing to extend the allowance to
use the derived 5-cycle method to ICIs.
Third, we are taking steps to further
clean up the regulatory language. This
involves removing several sections that
apply only for model years before 2008
and moving or combining several of the
remaining sections to provide a clearer
organization. We are also being more
careful with regulatory references
pointing to other sections within 40 CFR
part 600 and to sections in 40 CFR part
86. This largely addresses the concern
that regulatory sections numbered for
certain model years can cause references
to be incorrect or misleading over time.
We are proposing to rely on the
rounding convention as specified for
engine testing in 40 CFR part 1065.
Similarly, we are proposing to rely on
the hearing procedures specified in 40
CFR part 1068. These changes allow us
to centralize provisions that have
general applicability to support our
effort to have a consistent approach
across programs. The proposed
regulations also include a streamlined
set of references to outside standards
(such as SAE standards). For the final
rule, we also intend to include the most
recent updates for the ASTM standards
we reference in part 600. We are not
intending to make any substantive
changes to the regulatory provisions
affected by these administrative changes
and are not reopening the rule for any
of those provisions. Nevertheless, we
request comment on these changes and
on any further steps that would be

VII. Projected Impacts of the Proposed
Requirements
Vehicle manufacturers have been
required to provide fuel economy labels
on vehicles since 1977. The costs and
benefits of label revisions would be
those associated with changes to the
current label, not the costs and benefits
associated with production of the label
itself. The change in cost from this
proposed rule comes in the physical
revisions to the label itself and the
possible efficiencies achieved by
meeting EPCA and EISA labeling
requirements in one label, as well as
proposed modified vehicle testing
procedures, and any revisions of
currently provided information that
consumers find useful in informing
their purchase decisions. The benefits of
the rule come from providing labels for
mass-market advanced technology
vehicles for the first time, and from any
improvements in the effectiveness of
labels for conventional vehicles in
providing accurate and useful consumer
information on fuel consumption and
environmental performance.
A. Costs Associated With This Rule
Testing requirements for vehicles are
not new. Advanced technology and
alternative fuel vehicles have been
required to undergo testing
requirements in the past. For advanced
technology vehicles, though, the test
procedures have not previously been
standardized; they have been handled
on a case-by-case basis. Because EPA
expects more advanced technology
vehicles to come to market, we propose
to codify testing procedures in a public
process and are requesting comment on
them. See section VI of this preamble.
The testing costs described here
therefore are not really new costs for
manufacturers, since they would have to
test the vehicles even in the absence of
this rule. The cost estimates are
provided here because they have
previously not been presented, and EPA
seeks comment on the analysis of costs
presented here.
The analysis of the projected costs of
this rule follows conceptually the
approach in the 2006 (‘‘five-cycle’’) fuel
economy labeling rule. Increased ongoing operations and maintenance
(O&M) costs and labor hours result from
the costs of printing the labels and
increases in testing costs for electric
vehicles (EVs) and plug-in hybrids
(PHEVs). We also allow for the costs of
increased facility capacity to
accommodate the increased testing time
involved for these two categories of

vehicles. Startup costs are treated as
capital costs, and are amortized over ten
years at 7% interest. Startup costs for
this rule include some one-time graphic
design work for each manufacturer
subject to the rule and updating
information systems and testing
equipment for those manufacturers
subject to new testing. As an aid to the
analysis and to help articulate the range
of uncertainty, we include both low and
high cost estimates for each of these cost
and labor hour elements. The cost
estimates are $649,000 per year for the
low estimate, and $2.8 million per year
for the high estimate. For details of this
analysis, see the ‘‘Draft Supporting
Statement for Information Collection
Request, Fuel Economy Labeling of
Motor Vehicles (Proposed Rule),’’ in the

Electric Vehicles
i. Testing Requirements for Electric
Vehicles
As explained in Section VI of this
Preamble, EPA currently has no federal
test procedure for measuring fuel
economy for electric vehicles (EVs). To
date, EPA has performed some fuel
economy testing connected with
certification applications for electric
vehicles using the procedures
developed by the Society of Automotive
Engineers (SAE), specifically SAE J1634,
as cancelled in October 2002. This
proposal spells out EV testing
requirements that are similar to SAE
J1634, as cancelled in October 2002, and
allows continued use of that procedure.
In estimating the costs of this action,
there is no clear baseline cost that
manufacturers of EVs would have
incurred in satisfying federal
requirements, because existing fuel
economy measurements are entirely
specified in terms of exhaust and
greenhouse gas emissions. For purposes
of the analysis, we assume these EV
costs are entirely new costs rather than
increments to pre-existing costs. Here
and in the facility costs section, this also
means we assume no carry-over
applications for EVs. Both these
assumptions are more likely to lead to
an overstatement of costs than an
understatement.

In 2004 the Federal Trade
Commission promulgated a rule
requiring ‘‘alternative fueled vehicles’’ to
include a consumer label indicating
their estimated cruising ranges (69 FR
26926, April 9, 2004; 16 CFR part 309,
subpart C). The covered vehicles
include EVs but not plug-in hybrid
electric vehicles (PHEVs). Estimated
cruising range for an EV is the range
determined according to SAE J1634 (16
CFR 309.22(a)(2)). Consequently, EV
manufacturers selling vehicles in the
United States have already been subject
to the same SAE J1634 testing
requirements allowed in this
rulemaking for several years. However,
for purposes of the analysis below we
treat the costs of compliance for
manufacturers subject to the proposed
rule as new costs in order to insure that
they are fully considered in this
rulemaking,
The salient feature of SAE J1634 for
cost purposes is that it requires, similar
to a conventional vehicle, the Federal
Test Procedure (FTP or City Test),
preceded by vehicle preparation; this is
followed by the Highway Test (HFET).
The off-cycle tests (USO6, SCO3, cold
FTP) are optional under EPA’s proposal.
Furthermore, cruising range
determination requires that the FTP be
repeated until the battery system is no
longer able to maintain the FTP speed
tolerances; the FTP in question is the
full four-phase FTP, repeated as cold
and hot start ‘‘UDDS’’ or ‘‘LA–4’’ cycles
until that point is reached.
Preparation costs are estimated to be
$3,163 and 30 hours per vehicle, per
Information Collection Request (ICR)
0783.54 (OMB 2060–0104), the
certification ICR for conventional
vehicles. Preparation includes several
coast downs, a UDDS, and a soak
period. The low and high EV test
distances for FTP and HFET tests are
estimated as 50 to 250 miles. For
purposes of this estimate, the cost of an
FTP/HFET pair is $1,860, allocated 70%
to the FTP and 30% to the HFET and
incremented either by 50 or 250 divided
by 7.45 (the distance of a normal FTP),
or by 50 or 250 divided by 10.3 (the
distance of the normal HFET). These
increases are applied to an estimated
five to eight EV families in the years
through MY2013. Labor hours,
estimated at 30 hours per FTP/HFET
pair, are allocated and incremented in a
similar manner. The bottom line is a
cost between $75,300 and $486,784, and
1,073 to 7,625 hours, per year for the EV
industry.

Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
ii. Testing Requirements for Plug-In
Hybrid Electric Vehicles
As explained in Section VI, the
proposed EPA test procedure for PHEVs
is an extension of the existing test
procedure for hybrid vehicles. Off-cycle
tests are already required for test groups
that do not meet the ‘‘litmus test;’’ others
would use the derived five-cycle
adjustment. Hybrid vehicles already do
FTP and HFET tests for fuel economy
determination. The new FTP procedure
would essentially run repeated FTPs
until the charge is depleted. This is the
‘‘charge-depleting’’ operation, when the
vehicle is mainly running on its battery.
The battery would then be recharged,
and a single additional four-phase FTP
would be conducted in what is
denominated as the ‘‘charge-sustain’’
operation. Following this, the vehicle
will be recharged, if necessary, by
running any appropriate test cycle
followed by HFET cycles in chargedepleting operation, followed by a cycle
in charge-sustain operation.
For purposes of this cost analysis, the
charge-sustain FTP and HFET cycles
along with potential other cycles
mandated by emissions and fuel
economy testing requirements are
considered to be continuations of
existing requirements. The cost
increment due to this proposal
consequently derives entirely from the
increased testing time in depleting
mode. The duration of the depleting
modes is estimated as 7.45 to 50 miles
over the repeated 7.45 mile FTP or 10.3
mile HFET test cycles. These together,
applied to 5 to 8 families with no
carryovers, add an estimated $8,528 to
$80,564 in operation and maintenance
(O&M) costs and 138 to 923 labor hours
to existing hybrid testing costs.
b. Printing Costs for New Labels
The primary variable cost for the new
label design is the difference in cost
between black-and-white and color
printing. To estimate this cost
difference, the agencies note two
sources. First, in 2007 the California Air
Resources Board (CARB) examined the
effects of requiring an environmental
label that included color printing. It
estimated the combined capital and
operating costs of color labels to be as
low as $0.02 per vehicle for large
manufacturers;194 CARB expected
small-scale manufacturers to switch to
pre-printed color labels at an
incremental cost of $0.05 per label, for
58149
a 4-by-6-inch label. Secondly, in 2006
Hewlett-Packard estimated the per-page
cost of color printing on its HP Color
LaserJet 4700n printer as $0.09 per
letter-sized page, and black-and-white
printing on a dedicated black-and-white
printer as $0.015, for a cost difference of
$0.075 per page.195
The existing fuel economy label
measures 4.5 by 7 inches, slightly larger
than the CARB label but about 1⁄3 the
size of a standard page. For the cost
estimates developed here, the agencies
consider a low estimate of $0.03 per
label in additional printing costs (based
on the CARB label, adjusted for size),
and a high estimate of $0.08 per label
(based on the HP estimate, which may
overestimate the cost based on page
size). For the number of labels, we
estimate the subject fleet from the April
20, 2010, U.S. Department of
Transportation’s Summary of Fuel
Economy Performance,196 taking
MY2009’s 9.83 million as the low and
MY2005’s 15.9 million as the high
estimate. This yields a new printing cost
of $294,690 to $1,274,634 per year.
The O&M costs and labor hours
discussed above can be summarized as

2. Facility Costs
In addition to new equipment (treated
as a startup cost, below), the new testing
requirements for EVs and PHEVs will in
theory require expanded testing
facilities for those manufacturers
choosing to produce and sell them in
the U.S. Because the cost of new facility
capacity is highly dependent on
manufacturer-specific factors (the costs
of capital, the availability of land, the
structure of work shifts, the existing
excess capacity, etc.), we use the
approximation of unitizing increased
test costs by assuming that a facility
capable of performing 750 FTP/HFET
pairs would cost $4 million. Here, the
new tests are deemed to require these
facilities in proportion to the increases
in test time, and the costs are then
annualized over ten years and amortized
at 7% interest compounded monthly.
This assumption is more likely to
produce an overestimate of costs rather
than an underestimate, since it does not
attempt to account for the current excess
capacity that exists in manufacturers’
current test facilities. We assume that
there is no excess capacity in our
analysis. Note that other features of the
EV and PHEV test cycles, such as
recharging times, have been harmonized
with existing test protocols.
Furthermore, consistent with other
information burden analyses for the
emissions and fuel economy programs,
we consider these as ongoing rather
than startup costs (i.e., as the facilities
depreciate they are continually being
replaced), another conservative
assumption. Applying these costs to a
low and high estimate of 5 to 8 EV
families and 5 to 8 PHEV families per
year yields an annualized facilities cost
between $25,278 and $210,779 per year.
Facility costs can be summarized as in

3. Startup Costs
Startup costs are counted as one-time
costs that are amortized or discounted at
an interest rate of 7% over ten years.
a. Updating Information Systems and
Testing Equipment
The estimate includes the cost of
upgrading information systems for the
estimated 8 to 10 manufacturers who
will need to comply with the new EV
and PHEV testing requirements, such as
recording multiple tests, recording
battery charge data, and communicating
the resulting data to the information
system that gets it to EPA and the label.
Both low and high estimates use 4
weeks for four IT staff for analysis and
code, and 4 weeks for two IT staff for
testing, at $100 per hour, for each
manufacturer, resulting in an industry
cost of $768,000 to $960,000. In
addition, each manufacturer who has
not previously produced hybrid-electric
vehicles is assumed to need new testing
equipment costing $25,000 for an
ammeter and $50,000 for voltage
stabilizers; we estimate that 5–8
manufacturers will fall in this category.
b. Label Redesign
The proposed label designs are
presented in Section III. The changes
being proposed in this rule would not
affect either the existence or size of the
label. Auto companies currently have
significant flexibility in whether fuel
economy label should be a stand-alone
label or included in the ‘‘Monroney
label’’ (which provides information on
the price and options included for a
specific vehicle), or where it is placed
on the Monroney label. The agencies are
not proposing any changes to this
flexibility. The agencies estimate 16 to
24 hours at $100 per hour for this work,
assuming at this time that no specific
location or size within the Monroney
label is required. This cost is applied to
the universe of separate manufacturer
entities subject to the rule. Many
specific automotive brands are parts of
marketing groups or are owned and
managed by other, parent companies.
Allowing for these relationships, the
best guess is that the rule would apply
to 24 manufacturers and 11 independent
commercial importers (ICIs) importing
nonconforming vehicles into the U.S.
for sale. Applied to 35 companies, then,
the label redesign cost is estimated to be
$56,000 to $84,000.
c. Annualized Startup Costs
Total startup costs are between $1.2
and $1.6 million. When annualized and
subjected to 7% loan repayment/
discounting, the startup costs total
$170,711 to $234,069 per year. These
are summarized in Table VII.A.3–1:

Table VII.A.4–1 summarizes the costs
presented here. The total costs of this
rule, excluding labor, are estimated to
be about $575,000 to $2,287,000 per
year. Adding the cost of labor (estimated
to be $61.49 per hour overall) to the
above estimates brings the total cost to
$648,952 to $2,812,465. Note that
startup capital is not budgeted as labor.

B. Impact of Proposing One Label To
Meet EPCA/EISA
As discussed in Section I.C., EPCA
and EISA create similar but not
identical requirements for labeling
vehicles. EPA conducts a labeling
program under EPCA, and NHTSA is
required to conduct a labeling program
under EISA, in consultation with EPA.
While the agencies could require that
manufacturers produce two separate
labels to meet the requirements of the
statutes, much of the information on the
two labels would be duplicative. In
addition, two different fuel economy
labels might confuse vehicle purchasers,
frustrating the purpose of providing fuel
economy information to purchasers.
Requiring that auto makers put two fuel
economy labels on vehicles would also
crowd the limited labeling space on
vehicles. For these reasons, EPA and
NHTSA are proposing to combine both
the EPCA and the EISA requirements
into one label.
Because NHTSA’s labeling under
EISA is a new requirement that has not
previously been implemented, there is
no cost reduction associated with the
proposal to use a joint label. The use of
the joint label avoids a cost increase that
would result from two separate labels.
EPA and NHTSA are not including this
cost saving in the cost analysis because
we believe that the benefits of
coordinating labeling requirements
outweigh any possible disadvantages.
C. Benefits of Label Changes
The benefits of this rule would come
from improved provision of information
to vehicle buyers, and more informed
VerDate Mar<15>2010
18:48 Sep 22, 2010
Jkt 220001
consumer decisions resulting from the
changes. These benefits are difficult to
estimate. Doing so would require
predictions of changes in consumer
behavior as a result of the label
modifications. The internet survey
discussed in Section IV.A.2 is intended
to provide some insights into the
comprehensibility and usefulness of the
labels, but the results are not available
at this time. We caution that insights
into comprehensibility and usefulness
may be limited in predicting changes in
consumer behavior due to the proposed
label change.
Improved fuel economy reduces costs
of driving a mile, but the technology to
improve fuel economy may increase the
cost of a vehicle. Evaluating this tradeoff
requires comparing future fuel savings
based on expectations of future fuel
prices and driving patterns with known
and immediate increases in vehicle
purchase price. Some evidence suggests
that consumers may not accurately
compare future fuel savings with the upfront costs of fuel-saving technology
when buying vehicles.197 As a result,
consumers may buy less or more fuelsaving technology than is financially
sensible for them to buy. This problem
may be compounded by the presence of
miles per gallon (MPG) as a primary
metric for fuel economy comparison.198
As discussed in Section II.A.2,
consumers can save much more fuel by
197 Turrentine, Thomas S., and Kenneth S.
Kurani, ‘‘Car buyers and fuel economy?’’ Energy
Policy 35 (2007): 1213–1223.

MPG Illusion.’’ Science 320 (5883) (June 20, 2008):

choosing a 1–MPG improvement in fuel
economy for a low-MPG vehicle than by
choosing a 1–MPG improvement for a
high-MPG vehicle. However, research
on the ‘‘MPG illusion’’ finds that
consumers expect a 1–MPG
improvement to produce the same fuel
savings regardless of the efficiency of a
vehicle.199 Thus, the tendency of
consumers to use MPG as a primary
metric for fuel economy increases the
difficulty of estimating the fuel savings
resulting from increased fuel economy.
As a result, consumers may not be able
to find the most cost-effective amount of
fuel economy for their driving habits.
For gasoline vehicles, new metrics on
the label, such as gallons per hundred
miles, fuel savings over 5 years, or
environmental metrics, may make it
easier for consumers to identify the fuel
savings they are likely to receive from
a vehicle, and therefore to judge better
between vehicles with different fuel
savings, costs, and environmental
impacts.
Finding the most cost-effective
vehicle may be even more confusing
with the advent of advanced technology
vehicles such as EVs or PHEVs. Most
consumers are not accustomed to
shopping for vehicles that use energy
sources other than gasoline. In addition,
the cost effectiveness of different
technologies depends on a person’s
driving patterns. A person with a short
commute may have lower per-mile costs
with a vehicle with some all-electric
range, but someone with a long
commute may have higher per-mile

costs or insufficient range with such a
vehicle and may want to consider
different technologies. For advanced
technology vehicles, the label can help
vehicle shoppers to understand the new
technologies, and it can present metrics
that allow consumers to make useful
comparisons across different vehicle
technologies.
EPA and NHTSA request comment on
the benefits described here, and on any
additional benefits.
D. Summary
The primary benefits associated with
this proposed rule are associated with
improved consumer decision-making
resulting from improved presentation of
information. At this time, EPA and
NHTSA do not have data to quantify
these impacts.
The primary costs associated with this
proposed rule come from revisions to
the fuel economy label and additional
testing procedures. These costs are
estimated to be $649,000–$2.8 million
per year.
EPA and NHTSA request comment on
this assessment of the benefits and
costs.
VIII. Agencies’ Statutory Authority and
Executive Order Reviews
A. Relationship of EPA’s Proposed
Requirements With Other Statutes and
Regulations
mstockstill on DSKH9S0YB1PROD with PROPOSALS3
1. Automobile Disclosure Act
The Automobile Information
Disclosure Act (AIDA) requires the
affixing of a retail price sticker to the
windshield or side window of new
automobiles indicating the
Manufacturer’s Suggested Retail Price,
the ‘‘sticker price.’’ 200 Additional
information, such as a list of any
optional equipment offered or
transportation charges, is also required.
The Act prohibits the sticker from being
removed or altered prior to sale to a
consumer.
Under EPCA, EPA may allow
manufacturers of new automobiles to
comply with the EPCA labeling
requirements by placing the fuel
economy information on the label
required by AIDA.201 Normally, the
price sticker label and EPA label are
combined as one large label. Failure to
maintain the EPA label on the vehicle
is considered a violation of AIDA.
200 More commonly known as the Monroney Act
(Senator Mike Monroney was the chief sponsor of
the Act) or Price Sticker Act. See 15 U.S.C. 1231–
1233.

2. Internal Revenue Code
EPCA requires ‘‘Gas Guzzler’’ tax
information to be included on the fuel
economy label, under 26 U.S.C.
4064(c)(1). The Internal Revenue code
contains the provisions governing the
administration of the Gas Guzzler Tax.
It contains the table of applicable taxes
and defines which vehicles are subject
to the taxes. The IRS code specifies that
the fuel economy to be used to assess
the amount of tax will be the combined
city and highway fuel economy as
determined by using the procedures in
place in 1975, or procedures that give
comparable results (similar to EPCA’s
requirements for determining CAFE for
passenger automobiles). This proposal
would not impact these provisions.
3. Clean Air Act
EPCA states that fuel economy tests
shall, to the extent practicable, be
carried out with the emissions tests
required under Section 206 of the Clean
Air Act.202 EPA is not proposing
additional emissions tests.
4. Federal Trade Commission Guide
Concerning Fuel Economy Advertising
for New Vehicles
In the mid-1970’s when EPCA was
passed, the Federal Trade Commission
(FTC) ‘‘took note of the dramatic
increase in the number of fuel economy
claims then being made and of the
proliferation of test procedures then
being used as the basis for such
claims.’’ 203 They responded by
promulgating regulations in 16 CFR part
259 entitled ‘‘Guide Concerning Fuel
Economy Advertising for New Vehicles’’
(‘‘Fuel Guide’’). The Fuel Guide, adopted
in 1975 and subsequently revised twice,
provides guidance to automobile
manufacturers to prevent deceptive
advertising and to facilitate the use of
fuel economy information in
advertising. The Fuel Guide advises
vehicle manufacturers and dealers how
to disclose the established fuel economy
of a vehicle, as determined by the
Environmental Protection Agency’s
rules pursuant to the Automobile
Information Disclosure Act (15 U.S.C.
2996), in advertisements that make
representations regarding the fuel
economy of a new vehicle.204 The
disclosure is tied to the claim made in
the advertisement. If both city and
highway fuel economy claims are made,
both city and highway EPA figures
should be disclosed. A claim regarding
either city or highway fuel economy

FR 42003, Sept. 10, 1975.
204 43 FR 55747, Nov. 29, 1978; and 60 FR 56230,
Nov. 8, 1995.
should be accompanied by the
corresponding EPA figure. A general
fuel economy claim would trigger
disclosure of the EPA city figure,
although the advertiser would be free to
state the highway figure as well. The
authority for the Fuel Guide is tied to
the Federal Trade Commission Act (15
U.S.C. 41–58) which, briefly stated,
makes it illegal for one to engage in
‘‘unfair methods of competition in or
affecting commerce and unfair or
deceptive acts or practices in or
affecting commerce.’’
5. California Environmental
Performance Label
California requires each new and used
vehicle offered for sale in the state to
affix a ‘‘Smog Index Number’’ and
‘‘Global Warming Index’’ decal to the car
window which indicates the pollution
standard that applies to that particular
car, and its exhaust emissions.205 This
proposal would not impact California’s
regulations. The Global Warming index
on California’s label includes emissions
from fuel production (https://www.
driveclean.ca.gov/images/ep_label_

B. Statutory and Executive Order
Reviews
1. Executive Order 12866: Regulatory
Planning and Review and DOT
Regulatory Policies and Procedures
(NHTSA Only)
Under Executive Order (EO) 12866
(58 FR 51735, October 4, 1993), this
action is a ‘‘significant regulatory action’’
because the action raises novel legal or
policy issues. Accordingly, EPA and
NHTSA submitted this action to the
Office of Management and Budget
(OMB) for review under E.O. 12866 and
any changes made in response to OMB
recommendations have been
documented as OMB requests in the
docket for this action.
NHTSA is also subject to the
Department of Transportation’s
Regulatory Policies and Procedures.
This proposed rule is also significant
within the meaning of the DOT
Regulatory Policies and Procedures.
E.O. 12866 also requires NHTSA to
submit this action to OMB for review
and document any changes made in
response to OMB recommendations
In addition, EPA and NHTSA both
prepared an analysis of the potential
costs and benefits associated with this
action. This analysis is available in
Section VII of this document.

2. Paperwork Reduction Act
The information collection
requirements in this proposed rule have
been submitted for approval to the
Office of Management and Budget
(OMB) under the Paperwork Reduction
Act, 44 U.S.C. 3501 et seq. The
Information Collection Request (ICR)
document prepared by EPA has been
assigned EPA ICR number 2392.01.
Since this is a joint proposal, the burden
associated with these information
collection requirements could be
attributed to either agency. However,
since a significant portion of the burden
result from new EPA testing
requirements, EPA has agreed to assume
responsibility for the complete
paperwork burden. Both agencies will
consider the comments submitted
regarding these potential costs as part of
their decision in the final rule.
The information being collected is
used by EPA to calculate the fuel
economy estimates that appear on new
automobile, light truck and mediumduty passenger vehicle sticker labels.
EPA currently collects this information
annually as part of its vehicle
certification and fuel economy program,
and will continue to do so. This
proposed rule changes some of the
content of the information submitted.
Responses to this information collection
are mandatory to obtain the benefit of
vehicle certification under Title II of the
Clean Air Act (42 U.S.C. 7521 et seq.)
and as required under Title III of the
Motor Vehicle Information and Cost
Savings Act (15 U.S.C. 2001 et seq.).
Information submitted by manufacturers
is held as confidential until the specific
vehicle to which it pertains is available
for purchase. After vehicles are
available for purchase, most information
associated with the manufacturer’s
application is available to the public.
Under section 208 of the Clean Air Act
(42 U.S.C. 7542(c)), all information,
other than trade secret processes or
methods, must be publicly available.
Proprietary information is granted
confidentiality in accordance with the
Freedom of Information Act, EPA
regulations at 40 CFR part 2, and class
determinations issued by EPA’s Office
of General Counsel.
The projected yearly increased cost
within the three-year horizon of the
pending information collection request
is $2,812,000 including $2,286,000 in
operations and maintenance costs and
$526,000 in labor costs. The estimated
number of likely respondent
manufacturers is 35. Responses are
submitted annually by engine family,
with the number of responses per
respondent varying widely depending
on the number of engine families being
certified. Under the current fuel
economy information authorization, an
average of 12.2 responses a year are
approved for each of 33 respondents
requiring 451.2 hours per response and
80 hours of recordkeeping at a total cost
of $10,012 per response for an industry
total of 184,127 hours and $4,274,932
million annually, including capital and
operations and maintenance costs.
Burden is defined at 5 CFR 1320.3(b).
An agency may not conduct or
sponsor, and a person is not required to
respond to, a collection of information
unless it displays a currently valid OMB
control number. The OMB control
numbers for EPA’s regulations in 40
CFR are listed in 40 CFR part 9.
To comment on the EPA’s need for
this information, the accuracy of the
provided burden estimates, and any
suggested methods for minimizing
respondent burden, EPA has established
a public docket for this rule, which
includes this ICR, under Docket ID
number EPA–HQ–OAR–2009–0865.
Submit any comments related to the ICR
to EPA and OMB. See ADDRESSES
section at the beginning of this notice
for where to submit comments to EPA.
Send comments to OMB at the Office of
58153
Information and Regulatory Affairs,
Office of Management and Budget, 725
17th Street, NW., Washington, DC
20503, Attention: Desk Office for EPA.
Since OMB is required to make a
decision concerning the ICR between 30
and 60 days after September 23, 2010,
a comment to OMB is best assured of
having its full effect if OMB receives it
by October 25, 2010. The final rule will
respond to any OMB or public
comments on the information collection
requirements contained in this proposal.
3. Regulatory Flexibility Act
The Regulatory Flexibility Act (RFA)
generally requires agencies to prepare a
regulatory flexibility analysis of any rule
subject to notice and comment
rulemaking requirements under the
Administrative Procedure Act or any
other statute unless the agencies certify
that the rule will not have a significant
economic impact on a substantial
number of small entities. Small entities
include small businesses, small
organizations, and small governmental
jurisdictions.
For purposes of assessing the impacts
of this proposed rule on small entities,
a small entity is defined as: (1) A small
business as defined by the Small
Business Administration (SBA) by
category of business using North
America Industrial Classification
System (NAICS) and codified at 13 CFR
121.201; (2) a small governmental
jurisdiction that is a government of a
city, county, town, school district or
special district with a population of less
than 50,000; and (3) a small
organization that is any not-for-profit
enterprise which is independently
owned and operated and is not
dominant in its field.

emissions compliance and labeled for
fuel economy purposes. Small
governmental jurisdictions and small
organizations as described above will
not be impacted. We have determined
that the estimated effect of the proposed
rule is to impact 1 small business
vehicle manufacturer and 11 ICIs who
currently certify vehicles with costs less
than one percent of revenues. These 12
companies represent all of the small
businesses impacted by the proposed
regulations. The proposed regulations
will have no new impacts on small
business automobile dealers or small
business limousine and hearse
manufacturers. An analysis of the
impacts of the proposed rule on small
businesses has been prepared and
placed in the docket for this
rulemaking.206
Although this proposed rule will not
have a significant impact on a
substantial number of small entities, we
nonetheless have tried to reduce the
impact of this rule on small entities.
EPA is proposing to reduce the testing
burden on ICIs that would be needed for
the fuel economy label. Under the
proposal, ICIs would be allowed to test
over two driving cycles when
determining the fuel economy estimate
for the fuel economy label instead of
testing over five driving cycles as
required for vehicle manufacturers.
Both agencies continue to be
interested in the potential impacts of the
proposed rule on small entities and
welcome comments on the small
business analysis and other issues
related to impacts on small businesses.
4. Unfunded Mandates Reform Act
This proposed rule does not contain
a Federal mandate that may result in
expenditures of $100 million (adjusted
for inflation) or more for State, local,
and tribal governments, in the aggregate,
or the private sector in any one year.
This rule contains no federal mandates
for state, local, or tribal governments as
defined by the provisions of Title II of
the UMRA. The rule imposes no
enforceable duties on any of these
governmental entities. Nothing in the
rule would significantly or uniquely
affect small governments. The proposed
206 ‘‘Screening Analysis: Small Business Impacts
from Revisions to Motor Vehicle Fuel Economy
Label,’’ EPA report, August 12, 2010.

rule only affects vehicle manufacturers
and the agencies estimate annual costs
of less than $100 million (adjusted for
inflation). EPA and NHTSA believe that
the proposal represents the least costly,
most cost-effective approach to achieve
the statutory requirements of the rule.
The agencies’ estimated costs are
provided in section VI. Thus, this rule
is not subject to the requirements of
sections 202 or 205 of UMRA.
This rule is also not subject to the
requirements of section 203 of UMRA
because it contains no regulatory
requirements that might significantly or
uniquely affect small governments. As
noted above, the proposed rule only
affects vehicle manufacturers.
5. Executive Order 13132: Federalism
This action does not have federalism
implications. It will not have substantial
direct effects on the States, on the
relationship between the national
government and the States, or on the
distribution of power and
responsibilities among the various
levels of government, as specified in
Executive Order 13132. This rulemaking
would apply to manufacturers of motor
vehicles and not to state or local
governments. Thus, Executive Order
13132 does not apply to this action.
Although section 6 of Executive Order
13132 does not apply to this action, EPA
and NHTSA did consult with
representatives of state governments in
developing this action.
In the spirit of Executive Order 13132,
and consistent with the agencies’ policy
to promote communications between
Federal, State and local governments,
the agencies specifically solicits
comment on this proposed action from
State and local officials.
6. Executive Order 13175: Consultation
and Coordination With Indian Tribal
Governments
This action does not have tribal
implications, as specified in Executive
Order 13175 (65 FR 67249, November 9,
2000). This proposed rule would be
implemented at the Federal level and
imposes compliance costs only on
vehicle manufacturers. Tribal
governments would be affected only to
the extent they purchase and use
regulated vehicles. Thus, Executive
Order 13175 does not apply to this
action. The agencies specifically solicit
additional comment on this proposed
action from tribal officials.
7. Executive Order 13045: Protection of
Children From Environmental Health
and Safety Risks
EPA and NHTSA interpret E.O. 13045
(62 FR 19885, April 23, 1997) as
PO 00000
Frm 00078
Fmt 4701
Sfmt 4702
applying only to those regulatory
actions that concern health or safety
risks, such that the analysis required
under section 5–501 of the E.O. has the
potential to influence the regulation.
This action is not subject to E.O. 13045
because it does not establish an
environmental standard intended to
mitigate health or safety risks.
8. Executive Order 13211: Actions That
Significantly Affect Energy Supply,
Distribution or Use
This action is not a ‘‘significant energy
action’’ as defined in Executive Order
13211 (66 FR 28355 (May 22, 2001)),
because it is not likely to have a
significant adverse effect on the supply,
distribution, or use of energy. The
proposed regulations do not require
manufacturers to improve or otherwise
change the fuel economy of their
vehicles. The purpose of this proposed
regulation is to provide consumers with
better information on which to base
their vehicle purchasing decisions.
Therefore, we have concluded that this
rule is not likely to have any adverse
energy effects.
9. National Technology Transfer
Advancement Act
Section 12(d) of the National
Technology Transfer and Advancement
Act of 1995 (‘‘NTTAA’’), Public Law No.
104–113 (15 U.S.C. 272 note) directs the
agencies to use voluntary consensus
standards in its regulatory activities
unless to do so would be inconsistent
with applicable law or otherwise
impractical. Voluntary consensus
standards are technical standards (e.g.,
materials specifications, test methods,
sampling procedures, and business
practices) that are developed or adopted
by voluntary consensus standards
bodies. NTTAA directs the agencies to
provide Congress, through OMB,
explanations when the Agency decides
not to use available and applicable
voluntary consensus standards.
EPA’s portion of this proposed
rulemaking involves technical
standards. EPA proposes to use
elements of testing standards developed
with the Society of Automotive
Engineers (SAE). Where possible, EPA
proposes to incorporate by reference
portions of SAEJ1711, SAE J2841, and
SAE J1634. At the time of this proposal,
all the above SAE documents are either
open for update or in the process of
balloting prior to publishing. SAE
reference documents can be obtained at
https://www.SAE.org. In the absence of
final published reference documents,
EPA is proposing procedures that may
differ from final SAE procedures. Also,
differences between EPA proposed
E:\FR\FM\23SEP3.SGM
23SEP3
Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
procedures and final SAE procedures
may be due to statutory or existing
regulatory EPA requirements, worst case
emissions testing requirements by EPA,
and the need for EPA to address policy
concerns and concerns of manufacturers
not involved in developing SAE
procedures.
EPA welcomes comments on this
aspect of the proposed rulemaking and,
specifically, invites the public to
identify potentially-applicable
voluntary consensus standards and to
explain why such standards should be
used in this regulation.

40 CFR Chapter I
For the reasons set forth in the
preamble, the Environmental Protection
Agency proposes to amend parts 85, 86
and 600 of title 40, Chapter I of the Code
of Federal Regulations as follows:
PART 85—CONTROL OF AIR
POLLUTION FROM MOBILE SOURCES
Executive Order (EO) 12898 (59 FR
7629 (Feb. 16, 1994)) establishes federal
executive policy on environmental
justice. Its main provision directs
federal agencies, to the greatest extent
practicable and permitted by law, to
make environmental justice part of their
mission by identifying and addressing,
as appropriate, disproportionately high
and adverse human health or
environmental effects of their programs,
policies, and activities on minority
populations and low-income
populations in the United States.
The agencies have determined that
this proposed rule will not have
disproportionately high and adverse
human health or environmental effects
on minority or low-income populations
because it does not affect the level of
protection provided to human health or
the environment. The proposed
regulations do not require
manufacturers to improve or otherwise
change the emissions control or fuel
economy of their vehicles. The purpose
of this proposed regulation is to provide
consumers with better information on
which to base their vehicle purchasing
decisions.

manufacturers must comply with a full
useful life fleet average CO2 standard
calculated according to the provisions of
this paragraph (c). Manufacturers must
calculate separate full useful life fleet
average CO2 standards for their
passenger automobile and light truck
fleets, as those terms are defined in this
section. Each manufacturer’s fleet
average CO2 standards determined in
this paragraph (c) shall be expressed in
whole grams per mile, in the model year

(iii) EPA will determine the vehicles
not covered by a certificate because the
condition on the certificate was not
satisfied by designating vehicles in
those test groups with the highest
carbon-related exhaust emission values
first and continuing until reaching a
number of vehicles equal to the
calculated number of noncomplying
vehicles as determined in paragraph
(k)(8) of this section. If this calculation
determines that only a portion of
vehicles in a test group contribute to the
debit situation, then EPA will designate
actual vehicles in that test group as not
covered by the certificate, starting with
the last vehicle produced and counting
backwards.
(iv)(A) If a manufacturer ceases
production of passenger cars and light
trucks, the manufacturer continues to be
responsible for offsetting any debits
outstanding within the required time
period. Any failure to offset the debits
will be considered a violation of
paragraph (k)(8)(i) of this section and
may subject the manufacturer to an
enforcement action for sale of vehicles
not covered by a certificate, pursuant to
paragraphs (k)(8)(ii) and (iii) of this
section.
(B) If a manufacturer is purchased by,
merges with, or otherwise combines
with another manufacturer, the
controlling entity is responsible for
offsetting any debits outstanding within
the required time period. Any failure to
offset the debits will be considered a
violation of paragraph (k)(8)(i) of this
section and may subject the
manufacturer to an enforcement action
for sale of vehicles not covered by a
certificate, pursuant to paragraphs
(k)(8)(ii) and (iii) of this section.
(v) For purposes of calculating the
statute of limitations, a violation of the
requirements of paragraph (k)(8)(i) of
this section, a failure to satisfy the
conditions upon which a certificate(s)
was issued and hence a sale of vehicles
not covered by the certificate, all occur
upon the expiration of the deadline for
offsetting debits specified in paragraph

§ 600.007
Vehicle acceptability.
(a) All certification vehicles and other
vehicles tested to meet the requirements
of part 86 of this chapter (other than
those chosen under the durabilitydemonstration provisions in § 86.1829
of this chapter), are considered to have
met the requirements of this section.
(b) Any vehicle not meeting the
provisions of paragraph (a) of this
section must be judged acceptable by
the Administrator under this section in
order for the test results to be reviewed
for use in subpart C or F of this part. The
Administrator will judge the
acceptability of a fuel economy data
vehicle on the basis of the information
supplied by the manufacturer under
§ 600.006(b). The criteria to be met are:

Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
(1) A fuel economy data vehicle may
have accumulated not more than 10,000
miles. A vehicle will be considered to
have met this requirement if the engine
and drivetrain have accumulated 10,000
or fewer miles. The components
installed for a fuel economy test are not
required to be the ones with which the
mileage was accumulated, e.g., axles,
transmission types, and tire sizes may
be changed. The Administrator will
determine if vehicle/engine component
changes are acceptable.
(2) A vehicle may be tested in
different vehicle configurations by
change of vehicle components, as
specified in paragraph (b)(1) of this
section, or by testing in different inertia
weight classes. Also, a single vehicle
may be tested under different test
conditions, i.e., test weight and/or road
load horsepower, to generate fuel
economy data representing various
situations within a vehicle
configuration. For purposes of this part,
data generated by a single vehicle tested
in various test conditions will be treated
as if the data were generated by the
testing of multiple vehicles.
(3) The mileage on a fuel economy
data vehicle must be, to the extent
possible, accumulated according to
§ 86.1831 of this chapter.
(4) Each fuel economy data vehicle
must meet the same exhaust emission
standards as certification vehicles of the
respective engine-system combination
during the test in which the city fuel
economy test results are generated. This
may be demonstrated using one of the
following methods:
(i) The deterioration factors
established for the respective enginesystem combination per § 86.1841 of
this chapter as applicable will be used;
or
(ii) The fuel economy data vehicle
will be equipped with aged emission
control components according to the
provisions of § 86.1823 of this chapter.
(5) The calibration information
submitted under § 600.006(b) must be
representative of the vehicle
configuration for which the fuel
economy and carbon-related exhaust
emissions data were submitted.
(6) Any vehicle tested for fuel
economy or carbon-related exhaust
emissions purposes must be
representative of a vehicle which the
manufacturer intends to produce under
the provisions of a certificate of
conformity.
(7) For vehicles imported under
§ 85.1509 or § 85.1511(b)(2), (b)(4),
(c)(2), (c)(4) of this chapter, or (e)(2)
(when applicable) only the following

(i) For vehicles imported under
§ 85.1509 of this chapter, a highway fuel
economy value must be generated
contemporaneously with the emission
tests used for purposes of demonstrating
compliance with § 85.1509 of this
chapter. No modifications or
adjustments should be made to the
vehicles between the highway fuel
economy, FTP, US06, SC03 and Cold
temperature FTP tests.
(ii) For vehicles imported under
§ 85.1509 or § 85.1511(b)(2), (b)(4),
(c)(2), or (c)(4) of this chapter (when
applicable) with over 10,000 miles, the
equation in § 600.006(g)(3) shall be used
as though only 10,000 miles had been
accumulated.
(iii) Any required fuel economy
testing must take place after any safety
modifications are completed for each
vehicle as required by regulations of the
Department of Transportation.
(iv) Every vehicle imported under
§ 85.1509 or § 85.1511(b)(2), (b)(4),
(c)(2), or (c)(4) of this chapter (when
applicable) must be considered a
separate type for the purposes of
calculating a fuel economy label for a
manufacturer’s average fuel economy.

(e) If, based on a review of the
emission data for a fuel economy data
vehicle, submitted under § 600.006(b),
or emission data generated by a vehicle
tested under § 600.008(e), the
Administrator finds an indication of
non-compliance with section 202 of the
Clean Air Act, 42 U.S.C. 1857 et seq. of
the regulation thereunder, he may take
such investigative actions as are
appropriate to determine to what extent
emission non-compliance actually
exists.
(1) The Administrator may, under the
provisions of § 86.1830 of this chapter,
request the manufacturer to submit
production vehicles of the
configuration(s) specified by the
Administrator for testing to determine to
what extent emission noncompliance of
a production vehicle configuration or of
a group of production vehicle
configurations may actually exist.
(2) If the Administrator determines, as
a result of his investigation, that
substantial emission non-compliance is
exhibited by a production vehicle
configuration or group of production
vehicle configurations, he may proceed
with respect to the vehicle
configuration(s) as provided under
§ 600.206–08(b), § 600.206–12(b),
§ 600.207–08(c), or § 600.207–12(c) as

Test procedures.
This section provides test procedures
for the FTP, highway, US06, SC03, and
the cold temperature FTP tests. Testing
shall be performed according to test
procedures and other requirements
contained in this part 600 and in part 86
of this chapter, including the provisions
of part 86, subparts B, C, and S.
(a) FTP testing procedures. The test
procedures to be followed for
conducting the FTP test are those
prescribed in §§ 86.127 through 86.138
of this chapter, as applicable, except as
provided for in paragraph (b)(5) of this
section. (The evaporative loss portion of
the test procedure may be omitted
unless specifically required by the
Administrator.)
(b) Highway fuel economy testing
procedures. (1) The Highway Fuel
Economy Dynamometer Procedure
(HFET) consists of preconditioning
highway driving sequence and a
measured highway driving sequence.
(2) The HFET is designated to
simulate non-metropolitan driving with
an average speed of 48.6 mph and a
maximum speed of 60 mph. The cycle
is 10.2 miles long with 0.2 stop per mile
and consists of warmed-up vehicle
operation on a chassis dynamometer
through a specified driving cycle. A
proportional part of the diluted exhaust
emission is collected continuously for
subsequent analysis of hydrocarbons,
carbon monoxide, carbon dioxide using
a constant volume (variable dilution)
sampler. Diesel dilute exhaust is
continuously analyzed for hydrocarbons
using a heated sample line and analyzer.
Methanol and formaldehyde samples
are collected and individually analyzed
for methanol-fueled vehicles
(measurement of methanol and
formaldehyde may be omitted for 1993
through 1994 model year methanolfueled vehicles provided a HFID
PO 00000
Frm 00088
Fmt 4701
Sfmt 4702
calibrated on methanol is used for
measuring HC plus methanol).
(3) Except in cases of component
malfunction or failure, all emission
control systems installed on or
incorporated in a new motor vehicle
must be functioning during all
procedures in this subpart. The
Administrator may authorize
maintenance to correct component
malfunction or failure.
(4) The provisions of § 86.128 of this
chapter apply for vehicle transmission
operation during highway fuel economy
testing under this subpart.
(5) Section 86.129 of this chapter
applies for determination of road load
power and test weight for highway fuel
economy testing. The test weight for the
testing of a certification vehicle will be
that test weight specified by the
Administrator under the provisions of
part 86 of this chapter. The test weight
for a fuel economy data vehicle will be
that test weight specified by the
Administrator from the test weights
covered by that vehicle configuration.
The Administrator will base his
selection of a test weight on the relative
projected sales volumes of the various
test weights within the vehicle
configuration.
(6) The HFET is designed to be
performed immediately following the
Federal Emission Test Procedure,
§§ 86.127 through 86.138 of this
chapter. When conditions allow, the
tests should be scheduled in this
sequence. In the event the tests cannot
be scheduled within three hours of the
Federal Emission Test Procedure
(including one hour hot soak
evaporative loss test, if applicable) the
vehicle should be preconditioned as in
paragraph (b)(6)(i) or (ii) of this section,
as applicable.
(i) If the vehicle has experienced more
than three hours of soak (68 °F–86 °F)
since the completion of the Federal
Emission Test Procedure, or has
experienced periods of storage outdoors,
or in environments where soak
temperature is not controlled to 68 °F–
86 °F, the vehicle must be
preconditioned by operation on a
dynamometer through one cycle of the
EPA Urban Dynamometer Driving
Schedule, § 86.115 of this chapter.
(ii) EPA may approve a
manufacturer’s request for additional
preconditioning in unusual
circumstances
(7) Use the following procedure to
determine highway fuel economy:
(i) The dynamometer procedure
consists of two cycles of the Highway
Fuel Economy Driving Schedule
(§ 600.109–08(b)) separated by 15
seconds of idle. The first cycle of the

Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
Highway Fuel Economy Driving
Schedule is driven to precondition the
test vehicle and the second is driven for
the fuel economy measurement.
(ii) The provisions of § 86.135 of this
chapter, except for the overview and the
allowance for practice runs, apply for
highway fuel economy testing.
(iii) Only one exhaust sample and one
background sample are collected and
analyzed for hydrocarbons (except
diesel hydrocarbons which are analyzed
continuously), carbon monoxide, and
carbon dioxide. Methanol and
formaldehyde samples (exhaust and
dilution air) are collected and analyzed
for methanol-fueled vehicles
(measurement of methanol and
formaldehyde may be omitted for 1993
through 1994 model year methanolfueled vehicles provided a HFID
calibrated on methanol is used for
measuring HC plus methanol).
(iv) The fuel economy measurement
cycle of the test includes two seconds of
idle indexed at the beginning of the
second cycle and two seconds of idle
indexed at the end of the second cycle.
(8) If the engine is not running at the
initiation of the highway fuel economy
test (preconditioning cycle), the start-up
procedure must be according to the
manufacturer’s recommended
procedures. False starts and stalls
during the preconditioning cycle must
be treated as in § 86.136 of this chapter.
If the vehicle stalls during the
measurement cycle of the highway fuel
economy test, the test is voided,
corrective action may be taken
according to § 86.1834 of this chapter,
and the vehicle may be rescheduled for
testing. The person taking the corrective
action shall report the action so that the
test records for the vehicle contain a
record of the action.
(9) The following steps must be taken
for each test:
(i) Place the drive wheels of the
vehicle on the dynamometer. The
vehicle may be driven onto the
dynamometer.
(ii) Open the vehicle engine
compartment cover and position the
cooling fan(s) required. Manufacturers
may request the use of additional
cooling fans or variable speed fan(s) for
additional engine compartment or
under-vehicle cooling and for
controlling high tire or brake
temperatures during dynamometer
operation. With prior EPA approval,
manufacturers may perform the test
with the engine compartment closed,
e.g. to provide adequate air flow to an
intercooler (through a factory installed
hood scoop). Additionally, the
Administrator may conduct fuel
economy testing using the additional

fuel economy test, except that only one
exhaust sample collection bag and one
dilution air sample collection bag need
to be connected to the sample collection
systems.
(v) Operate the vehicle over one
Highway Fuel Economy Driving
Schedule cycle according to the
dynamometer driving schedule
specified in § 600.109–08(b).
(vi) When the vehicle reaches zero
speed at the end of the preconditioning
cycle, the driver has 17 seconds to
prepare for the emission measurement
cycle of the test.
(vii) Operate the vehicle over one
Highway Fuel Economy Driving
Schedule cycle according to the
dynamometer driving schedule
specified in § 600.109–08(b) while
sampling the exhaust gas.
(viii) Sampling must begin two
seconds before beginning the first
acceleration of the fuel economy
measurement cycle and must end two
seconds after the end of the deceleration
to zero. At the end of the deceleration
to zero speed, the roll or shaft
revolutions must be recorded.
(10) For alcohol-based dual fuel
automobiles, the procedures of
§ 600.111–08(a) and (b) shall be
performed for each of the fuels on
which the vehicle is designed to

read as follows:
§ 600.113–12 Fuel economy, CO2
emissions, and carbon-related exhaust
emission calculations for FTP, HFET, US06,
SC03 and cold temperature FTP tests.
The Administrator will use the
calculation procedure set forth in this
paragraph for all official EPA testing of
vehicles fueled with gasoline, diesel,
alcohol-based or natural gas fuel. The
calculations of the weighted fuel
economy and carbon-related exhaust
emission values require input of the
weighted grams/mile values for total
hydrocarbons (HC), carbon monoxide
(CO), and carbon dioxide (CO2); and,
additionally for methanol-fueled
automobiles, methanol (CH3OH) and
formaldehyde (HCHO); and,
additionally for ethanol-fueled
automobiles, methanol (CH3OH),
ethanol (C2H5OH), acetaldehyde
(C2H4O), and formaldehyde (HCHO);
and additionally for natural gas-fueled
vehicles, non-methane hydrocarbons
(NMHC) and methane (CH4). For
manufacturers selecting the fleet
averaging option for N2O and CH4 as
allowed under § 86.1818 of this chapter
the calculations of the carbon-related
exhaust emissions require the input of
grams/mile values for nitrous oxide
(N2O) and methane (CH4). Emissions
shall be determined for the FTP, HFET,
US06, SC03 and cold temperature FTP
tests. Additionally, the specific gravity,
carbon weight fraction and net heating
value of the test fuel must be
determined. The FTP, HFET, US06,
SC03 and cold temperature FTP fuel
economy and carbon-related exhaust
emission values shall be calculated as
specified in this section. An example
fuel economy calculation appears in
Appendix II of this part.
(a) Calculate the FTP fuel economy as
follows:
(1) Calculate the weighted grams/mile
values for the FTP test for CO2, HC, and

test fuel’s properties as specified in
paragraph (f) of this section.
(2) Calculate separately the grams/
mile values for the cold transient phase,
stabilized phase and hot transient phase
of the FTP test. For vehicles with more
than one source of propulsion energy,
one of which is a rechargeable energy
storage system, or vehicles with special
features that the Administrator
determines may have a rechargeable
energy source, whose charge can vary
during the test, calculate separately the
grams/mile values for the cold transient
phase, stabilized phase, hot transient
phase and hot stabilized phase of the
FTP test.
(b) Calculate the HFET fuel economy
as follows:
(1) Calculate the mass values for the
highway fuel economy test for HC, CO
and CO2, and where applicable, CH3OH,
C2H5OH, C2H4O, HCHO, NMHC, N2O

CH3OH, C2H5OH, C2H4O, HCHO,
NMHC, N2O and CH4 by dividing the
mass values obtained in paragraph (b)(1)
of this section, by the actual driving
distance, measured in miles, as
specified in § 86.135 of this chapter.

FTP fuel economy as follows:
(1) Calculate the weighted grams/mile
values for the cold temperature FTP test
for HC, CO and CO2, and where
applicable, CH3OH, C2H5OH, C2H4O,
HCHO, NMHC, N2O and CH4 as

chapter. For 2008 through 2010 dieselfueled vehicles, HC measurement is
optional.
(2) Calculate separately the grams/
mile values for the cold transient phase,
stabilized phase and hot transient phase
of the cold temperature FTP test in
§ 86.244 of this chapter.
(3) Measure and record the test fuel’s
properties as specified in paragraph (f)
of this section.
(d) Calculate the US06 fuel economy
as follows:
(1) Calculate the total grams/mile
values for the US06 test for HC, CO and
CO2, and where applicable, CH3OH,
C2H5OH, C2H4O, HCHO, NMHC, N2O

of this chapter, the manufacturer may,
with the advance approval of the
Administrator and using good
engineering judgment, optionally
analytically determine the grams/mile
values for the city and highway phases
of the US06 test. To analytically
determine US06 City and US06
Highway phase emission results, the
manufacturer shall multiply the US06
total grams/mile values determined in
paragraph (d)(1) of this section by the
estimated proportion of fuel use for the
city and highway phases relative to the
total US06 fuel use. The manufacturer
may estimate the proportion of fuel use
for the US06 City and US06 Highway
phases by using modal CO2, HC, and CO
emissions data, or by using appropriate
OBD data (e.g., fuel flow rate in grams
of fuel per second), or another method
approved by the Administrator.

resampled once a month to account for
any fuel property changes during
storage. Less frequent resampling may
be permitted if EPA concludes, on the
basis of manufacturer-supplied data,
that the properties of test fuel in the
manufacturer’s storage facility will
remain stable for a period longer than
one month. The fuel samples shall be
analyzed to determine the following fuel
properties:
(i) Specific gravity measured using
ASTM D 1298–99 (incorporated by
reference in § 600.011).
(ii) Carbon weight fraction measured
using ASTM D 3343–05 (incorporated

40. Section 600.208–12 is revised to
read as follows:
mstockstill on DSKH9S0YB1PROD with PROPOSALS3
§ 600.208–12 Calculation of FTP-based
and HFET-based fuel economy, CO2
emissions, and carbon-related exhaust
emissions for a model type.
(a) Fuel economy, CO2 emissions, and
carbon-related exhaust emissions for a
base level are calculated from vehicle
configuration fuel economy, CO2
emissions, and carbon-related exhaust
emissions as determined in § 600.206–
12(a), (b), or (c) as applicable, for lowaltitude tests.
(1) If the Administrator determines
that automobiles intended for sale in the
State of California and in section 177
states are likely to exhibit significant
differences in fuel economy, CO2
emissions, and carbon-related exhaust
emissions from those intended for sale
in other states, she will calculate fuel
economy, CO2 emissions, and carbonrelated exhaust emissions for each base
level for vehicles intended for sale in
California and in section 177 states and
for each base level for vehicles intended
for sale in the rest of the states.
(2) In order to highlight the fuel
efficiency, CO2 emissions, and carbonrelated exhaust emissions of certain
designs otherwise included within a
model type, a manufacturer may wish to
subdivide a model type into one or more
additional model types. This is
accomplished by separating
subconfigurations from an existing base
level and placing them into a new base
level. The new base level is identical to
the existing base level except that it
shall be considered, for the purposes of
this paragraph, as containing a new
basic engine. The manufacturer will be
permitted to designate such new basic
engines and base level(s) if:
(i) Each additional model type
resulting from division of another model
type has a unique car line name and that
VerDate Mar<15>2010

name appears on the label and on the
vehicle bearing that label;
(ii) The subconfigurations included in
the new base levels are not included in
any other base level which differs only
by basic engine (i.e., they are not
included in the calculation of the
original base level fuel economy values);
and
(iii) All subconfigurations within the
new base level are represented by test
data in accordance with
§ 600.010(c)(1)(ii).
(3) The manufacturer shall supply
total model year sales projections for
each car line/vehicle subconfiguration
combination.
(i) Sales projections must be supplied
separately for each car line-vehicle
subconfiguration intended for sale in
California and each car line/vehicle
subconfiguration intended for sale in
the rest of the states if required by the
Administrator under paragraph (a)(1) of
this section.
(ii) Manufacturers shall update sales
projections at the time any model type
value is calculated for a label value.
(iii) The provisions of paragraph (a)(3)
of this section may be satisfied by
providing an amended application for
certification, as described in § 86.1844
of this chapter.
(4) Vehicle configuration fuel
economy, CO2 emissions, and carbonrelated exhaust emissions, as
determined in § 600.206–12 (a), (b) or
(c), as applicable, are grouped according
to base level.
(i) If only one vehicle configuration
within a base level has been tested, the
fuel economy, CO2 emissions, and
carbon-related exhaust emissions from
that vehicle configuration will
constitute the fuel economy, CO2
emissions, and carbon-related exhaust
emissions for that base level.
(ii) If more than one vehicle
configuration within a base level has
been tested, the vehicle configuration
fuel economy values are harmonically
averaged in proportion to the respective
sales fraction (rounded to the nearest
0.0001) of each vehicle configuration
and the resultant fuel economy value
rounded to the nearest 0.0001 mile per
gallon; and the vehicle configuration
CO2 emissions and carbon-related
exhaust emissions are arithmetically
averaged in proportion to the respective
sales fraction (rounded to the nearest
0.0001) of each vehicle configuration
and the resultant carbon-related exhaust
emission value rounded to the nearest
tenth of a gram per mile.
(5) The procedure specified in
paragraph (a)(1) through (4) of this
section will be repeated for each base
level, thus establishing city, highway,

(7) For alcohol dual fuel automobiles
and natural gas dual fuel automobiles,
the procedures of paragraphs (a)(1)
through (6) of this section shall be used
to calculate two separate sets of city,
highway, and combined fuel economy,
CO2 emissions, and carbon-related

or diesel test fuel.
(ii) Calculate the city, highway, and
combined fuel economy, CO2 emissions,

or natural gas test fuel.
(b) For each model type, as
determined by the Administrator, a city,
highway, and combined fuel economy
value, CO2 emission value, and a
carbon-related exhaust emission value
will be calculated by using the projected
sales and values for fuel economy, CO2
emissions, and carbon-related exhaust
emissions for each base level within the
model type. Separate model type
calculations will be done based on the
vehicle configuration fuel economy, CO2
emissions, and carbon-related exhaust
emissions as determined in § 600.206–
12 (a), (b) or (c), as applicable.
(1) If the Administrator determines
that automobiles intended for sale in the
State of California and in section 177
states are likely to exhibit significant
differences in fuel economy, CO2
emissions, and carbon-related exhaust
emissions from those intended for sale
in other states, he or she will calculate
values for fuel economy, CO2 emissions,
and carbon-related exhaust emissions
for each model type for vehicles
intended for sale in California and in
section 177 states and for each model
type for vehicles intended for sale in the
rest of the states.
(2) The sales fraction for each base
level is calculated by dividing the
projected sales of the base level within
the model type by the projected sales of
the model type and rounding the
quotient to the nearest 0.0001.
(3)(i) The FTP-based city fuel
economy values of the model type
(calculated to the nearest 0.0001 mpg)
are determined by dividing one by a
sum of terms, each of which
corresponds to a base level and which
is a fraction determined by dividing:
(A) The sales fraction of a base level;
by
(B) The FTP-based city fuel economy
value for the respective base level.

paragraph (b)(3) of this section is
repeated in an analogous manner to
determine the highway and combined
fuel economy, CO2 emissions, and
carbon-related exhaust emissions for the
model type.
(5) For alcohol dual fuel automobiles
and natural gas dual fuel automobiles,
the procedures of paragraphs (b)(1)
through (4) of this section shall be used
to calculate two separate sets of city,
highway, and combined fuel economy
values and two separate sets of city,
highway, and combined CO2 and
carbon-related exhaust emission values
for each model type.
(i) Calculate the city, highway, and
combined fuel economy, CO2 emissions,
and carbon-related exhaust emission
values from the tests performed using
gasoline or diesel test fuel.
(ii) Calculate the city, highway, and
combined fuel economy, CO2 emissions,
and carbon-related exhaust emission
values from the tests performed using

(a) Base level. 5-cycle fuel economy
and CO2 emission values for a base level
are calculated from vehicle
configuration 5-cycle fuel economy and
CO2 emission values as determined in
§ 600.207 for low-altitude tests.
(1) If the Administrator determines
that automobiles intended for sale in the

for each base level for vehicles intended
for sale in California and for each base
level for vehicles intended for sale in
the rest of the states.
(2) In order to highlight the fuel
efficiency and CO2 emissions of certain
designs otherwise included within a
model type, a manufacturer may wish to
subdivide a model type into one or more
additional model types. This is
accomplished by separating
subconfigurations from an existing base
level and placing them into a new base
level. The new base level is identical to
the existing base level except that it
shall be considered, for the purposes of
this paragraph, as containing a new
basic engine. The manufacturer will be
permitted to designate such new basic
engines and base level(s) if:
(i) Each additional model type
resulting from division of another model
type has a unique car line name and that
name appears on the label and on the
vehicle bearing that label;
(ii) The subconfigurations included in
the new base levels are not included in
any other base level which differs only
by basic engine (i.e., they are not
included in the calculation of the
original base level fuel economy values);
and
(iii) All subconfigurations within the
new base level are represented by test
data in accordance with § 600.010(c)(ii).
(3) The manufacturer shall supply
total model year sales projections for
each car line/vehicle subconfiguration
combination.
(i) Sales projections must be supplied
separately for each car line-vehicle
subconfiguration intended for sale in
California and each car line/vehicle
subconfiguration intended for sale in
the rest of the states if required by the
Administrator under paragraph (a)(1) of
this section.
(ii) Manufacturers shall update sales
projections at the time any model type
value is calculated for a label value.
(iii) The provisions of this paragraph
(a)(3) may be satisfied by providing an
amended application for certification, as
described in § 86.1844 of this chapter.
(4) 5-cycle vehicle configuration fuel
economy and CO2 emission values, as
determined in § 600.207–12(a), (b), or
(c), as applicable, are grouped according
to base level.
(i) If only one vehicle configuration
within a base level has been tested, the
fuel economy and CO2 emission values
from that vehicle configuration
constitute the fuel economy and CO2
emission values for that base level.
(ii) If more than one vehicle
configuration within a base level has
been tested, the vehicle configuration
fuel economy values are harmonically

averaged in proportion to the respective
sales fraction (rounded to the nearest
0.0001) of each vehicle configuration
and the resultant fuel economy value
rounded to the nearest 0.0001 mile per

(iii) If more than one vehicle
configuration within a base level has
been tested, the vehicle configuration
CO2 emission values are arithmetically
averaged in proportion to the respective
sales fraction (rounded to the nearest
0.0001) of each vehicle configuration
and the resultant CO2 emission value
rounded to the nearest 0.1 gram per

(5) The procedure specified in
§ 600.209–12 (a) will be repeated for
each base level, thus establishing city
and highway fuel economy and CO2
emission values for each base level.
(6) [Reserved]
(7) For alcohol dual fuel automobiles
and natural gas dual fuel automobiles,
the procedures of paragraphs (a)(1)
through (6) of this section shall be used
to calculate two separate sets of city,
highway, and combined fuel economy
and CO2 emission values for each base
level.
(i) Calculate the city and highway fuel
economy and CO2 emission values from
the tests performed using gasoline or
diesel test fuel.
(ii) If 5-cycle testing was performed
on the alcohol or natural gas test fuel,
calculate the city and highway fuel
economy and CO2 emission values from
the tests performed using alcohol or
natural gas test fuel.
(b) Model type. For each model type,
as determined by the Administrator, city
and highway fuel economy and CO2
emissions values will be calculated by
using the projected sales and fuel
economy and CO2 emission values for
each base level within the model type.
Separate model type calculations will be
done based on the vehicle configuration
fuel economy and CO2 emission values
as determined in § 600.207, as
applicable.
(1) If the Administrator determines
that automobiles intended for sale in the
State of California are likely to exhibit
significant differences in fuel economy
and CO2 emissions from those intended
for sale in other states, he will calculate
fuel economy and CO2 emission values
for each model type for vehicles
intended for sale in California and for
each model type for vehicles intended
for sale in the rest of the states.
(2) The sales fraction for each base
level is calculated by dividing the
projected sales of the base level within
the model type by the projected sales of
the model type and rounding the
quotient to the nearest 0.0001.

automobiles, and for dual fuel
automobiles operated on gasoline or

(A) Determine city and highway fuel
economy values for vehicle operation
after the battery has been fully
discharged (‘‘gas only operation’’ or
‘‘charge-sustaining mode’’) as described
in paragraphs (a) and (b) of this section.
(B) Determine city and highway fuel
economy values for vehicle operation
starting with a full battery charge (‘‘allelectric operation’’ or ‘‘gas plus electric
operation’’, as appropriate, or ‘‘chargedepleting mode’’) as described in
§ 600.116–12. For battery energy,
convert W-hour/mile results to miles
per gasoline gallon equivalent or miles
per diesel gallon equivalent, as
applicable. Note that you must also
convert battery-based fuel economy
values to miles per kW-hr for
calculating annual fuel cost as described
in § 600.311–12.
(C) Calculate a composite city fuel
economy value and a composite
highway fuel economy value by
combining the separate results for
battery and engine operation using the
procedures described in § 600.116–12).
Apply the derived 5-cycle adjustment to
these composite values. Use these
values to calculate the vehicle’s
combined fuel economy as described in
paragraph (c)(1)(i) of this section.
(2) For the purposes of calculating the
combined CO2 emissions value for a
model type, to be used in displaying on
the label under subpart D of this part,
the manufacturer shall:
(i) For gasoline-fueled, diesel-fueled,
alcohol-fueled, and natural gas-fueled
automobiles, and for dual fuel
automobiles operated on gasoline or
diesel fuel, arithmetically average the
unrounded city and highway values,
determined in paragraphs (a)(1) or (2) of
this section and (b)(1) or (2) of this
section, weighted 0.55 and 0.45
respectively, and round to the nearest
whole gram per mile; or
(ii) For alcohol dual fuel and natural
gas dual fuel automobiles operated on
the alternate fuel, arithmetically average
the unrounded city and highway CO2
emission values from the tests
performed using the alternative fuel as
determined in paragraphs (a)(3) and
(b)(3) of this section, weighted 0.55 and
0.45 respectively, and round to the
nearest whole gram per mile.
(iii) CO2 label information is based on
tailpipe emissions only, so CO2
emissions from electric vehicles are
assumed to be zero.
(iv) For plug-in hybrid electric
vehicles, calculate combined CO2
emissions as follows:
(A) Determine city and highway CO2
emission rates for vehicle operation
after the battery has been fully
discharged (‘‘gas only operation’’ or

‘‘charge-sustaining mode’’) as described
in paragraphs (a) and (b) of this section.
(B) Determine city and highway CO2
emission rates for vehicle operation
starting with a full battery charge (‘‘allelectric operation’’ or ‘‘gas plus electric
operation’’, as appropriate, or ‘‘chargedepleting mode’’) as described in
§ 600.116–12. Note that CO2 label
information is based on tailpipe
emissions only, so CO2 emissions from
electric vehicles are assumed to be zero.
(C) Calculate a composite city CO2
emission rate and a composite CO2
emission rate by combining the separate
results for battery and engine operation
using the procedures described in
§ 600.116–12. Use these values to
calculate the vehicle’s combined fuel
economy as described in paragraph
(c)(1)(i) of this section.
(d) Calculating combined fuel
economy and CO2 emissions. (1) If the
criteria in § 600.115–11(a) are met for a
model type, both the city and highway
fuel economy and CO2 emissions values
must be determined using the vehiclespecific 5-cycle method. If the criteria in
§ 600.115–11(b) are met for a model
type, the city fuel economy and CO2
emissions values may be determined
using either method, but the highway
fuel economy and CO2 emissions values
must be determined using the vehiclespecific 5-cycle method (or modified 5cycle method as allowed under
§ 600.114–12(b)(2)).
(2) If the criteria in § 600.115 are not
met for a model type, the city and
highway fuel economy and CO2
emission label values must be
determined by using the same method,
either the derived 5-cycle or vehiclespecific 5-cycle.
(3) Manufacturers may use any of the
following methods for determining 5cycle values for fuel economy and CO2
emissions for electric vehicles:
(i) Generate 5-cycle data as described
in paragraph (a)(1) of this section.
(ii) Decrease fuel economy values by
30 percent and increase CO2 emission
values by 30 percent relative to data
generated from 2-cycle testing.
(iii) Manufacturers may ask the
Administrator to approve adjustment
factors for deriving 5-cycle fuel
economy results from 2-cycle test data
based on operating data from their inuse vehicles. Such data should be
collected from multiple vehicles with
different drivers over a range of
representative driving routes and
conditions. The Administrator may
approve such an adjustment factor for
any of the manufacturer’s vehicle
models that are properly represented by
the collected data.

determining the city and highway
model type fuel economy and CO2
emission values for general, unique or
specific fuel economy labels other than
those set forth in this subpart C for
advanced technology vehicles
including, but not limited to fuel cell
vehicles, hybrid electric vehicles using
hydraulic energy storage, and vehicles
equipped with hydrogen internal
combustion engines.
(2) For advanced technology vehicles,
the Administrator may prescribe special
methods for determining information
other than fuel economy that is required
to be displayed on fuel economy labels

53. A new § 600.311–12 is added to
subpart D to read as follows:
mstockstill on DSKH9S0YB1PROD with PROPOSALS3
§ 600.311–12 Determination of values for
fuel economy labels.
(a) Fuel economy. Determine city and
highway fuel economy values as
described in § 600.210–12(a) and (b).
Determine combined fuel economy
values as described in § 600.210–12(c).
Note that the label for plug-in hybrid
electric vehicles requires separate
values for combined fuel economy for
vehicle operation before and after the
vehicle’s battery is fully discharged; we
generally refer to these modes as

Jkt 220001
‘‘Blended Electric+Gas’’ (or ‘‘Electric
Only’’, as applicable) and ‘‘Gas only’’.
(b) CO2 emission rate. Determine the
engine-related CO2 emission rate as
described in § 600.210–12(d).
(c) Fuel economy grade. Determine a
vehicle’s fuel economy grade as follows:
(1) Determine the grade that applies
based on combined CO2 emission rates
from paragraph (b) of this section
according to the following table:

(2) We may update the grading scale
periodically based on the median CO2
emission rate for all model types. We
would do this by doubling the median
value from a given model year to
establish the nominal full range of CO2
values, then dividing this full range into
eleven equal intervals, after rounding to
the nearest whole number. For
reference, the grade distribution in
paragraph (c)(1) of this section is based
on a median value of 421 g/mi CO2.
(d) Fuel consumption rate. Calculate
the fuel consumption rate as follows:
(1) For vehicles with engines that are
not plug-in hybrid electric vehicles,
calculate the fuel consumption rate in
gallons per 100 miles (or gasoline gallon
equivalent per 100 miles for fuels other
than gasoline or diesel fuel) with the
following formula, rounded to the first
decimal place:
Fuel Consumption Rate = 100/MPG
Where:
MPG = The combined fuel economy value
from paragraph (a) of this section.
(2) For plug-in hybrid electric
vehicles, calculate two separate fuel
consumption rates as follows:
(i) Calculate the fuel consumption rate
based on engine operation after the
battery is fully discharged as described
in paragraph (d)(1) of this section.
(ii) Calculate the fuel consumption
rate during operation before the battery
is fully discharged in gasoline gallon
equivalent per 100 miles as described in
SAE J1711 (incorporated by reference in
§ 600.011), as described in § 600.116.
(3) For electric vehicles, calculate the
fuel consumption rate in kW-hours per
PO 00000
Frm 00114
Fmt 4701
Sfmt 4702
100 miles with the following formula,
rounded to the nearest whole number:
Fuel Consumption Rate = 100/MPG
Where:
MPG = The combined fuel economy value
from paragraph (a) of this section, in
miles per kW-hour.
(e) Annual fuel cost. Calculate annual
fuel costs as follows:
(1) Calculate the total annual fuel cost
with the following formula, rounded to
nearest whole number:
Annual Fuel Cost = [f1 × Fuel Price1/
MPG1 + f2 × Fuel Price2/MPG2] ×
Average Annual Miles
Where:
fi = The fraction of the vehicle’s overall
driving distance that is projected to
occur for fuel i. For vehicles that operate
on only one fuel, f1 = 1 and f2 = 0. For
plug-in hybrid electric vehicles,
determine the values of fi from SAE J
2841 (incorporated by reference in
§ 600.011). For dual fuel vehicles and
flexible fuel vehicles, disregard
operation on the alternative fuel.
Fuel Pricei = The estimated fuel price
provided by EPA for fuel i. The units are
dollars per gallon for gasoline and diesel
fuel, dollars per gasoline gallon
equivalent for natural gas, and dollars
per kW-hr for plug-in electricity.
MPGi = The combined fuel economy value
from paragraph (a) of this section for fuel
i. The units are miles per gallon for
gasoline and diesel fuel, miles per
gasoline gallon equivalent for natural
gas, and miles per kW-hr for plug-in
electricity.
Average Annual Miles = The estimated
annual mileage figure provided by EPA,
in miles.
(2) For plug-in hybrid electric
vehicles, calculate a separate annual
cost estimate using the equation in
paragraph (e)(1) of this section by
assuming the battery is never charged
from an external power source.
Similarly, calculate an annual cost
estimate by assuming the battery is
regularly charged from an external
power source such that it is never fully
discharged.
(f) Fuel savings. Calculate an
estimated five-year cost increment
relative to an average vehicle by
multiplying the rounded annual fuel
cost from paragraph (e) of this section
by 5 and subtracting this value from the
median five-year fuel cost. We will
calculate the median five-year fuel cost
from the annual fuel cost equation in
paragraph (e) of this section based on a
gasoline-fueled vehicle with a median
fuel economy value. The median fiveyear fuel cost is $10,000 for a 21-mpg
vehicle that drives 15,000 miles per year
with gasoline priced at $2.80 per gallon.
We may periodically update this
median five-year fuel cost to better
E:\FR\FM\23SEP3.SGM
23SEP3
Federal Register / Vol. 75, No. 184 / Thursday, September 23, 2010 / Proposed Rules
characterize the fuel economy for an
average vehicle. Round the calculated
five-year cost increment to the nearest
$100. Negative values represent a cost
increase compared to the average
vehicle.
(g) Other air pollutant score. Establish
a score for exhaust emissions other than
CO2 based on the applicable emission
standards as shown in Table 2 of this
section. For Independent Commercial
Importers that import vehicles not
58191
subject to Tier 2 emissions standards,
the air pollutant score for the vehicle is

(h) Ranges of fuel economy and CO2
emission values. We will determine the
range of combined fuel economy and
CO2 emission values for each vehicle
class identified in § 600.315. We will
generally update these range values
before the start of each model year based
on the lowest and highest values within
each vehicle class. We will also use this
same information to establish a range of
fuel economy values for all vehicles.
Continue to use the most recently
published numbers until we update
them, even if you start a new model year
before we publish the range values for
the new model year.
(i) Driving range. Determine the
driving range for certain vehicles as
follows:
(1) For electric vehicles, determine
the vehicle’s overall driving range as
described in Section 8 of SAE J1634
(incorporated by reference in § 600.011),
as described in § 600.116. Determine
separate range values for FTP-based city
and HFET-based highway driving, then
calculate a combined value by
arithmetically averaging the two values,
weighted 0.55 and 0.45 respectively,
and round to the nearest whole number.
(2) For natural gas vehicles, determine
the vehicle’s driving range in miles by
multiplying the combined fuel economy
described in paragraph (a) of this
section by the vehicle’s fuel tank
capacity, rounded to the nearest whole
number.
(3) For plug-in hybrid electric
vehicles, determine the battery driving
range and overall driving range as
described in SAE J1711 (incorporated by
reference in § 600.011), as described in
§ 600.116, as follows:
(i) Determine the vehicle’s Actual
Charge-Depleting Range, Rcda. Determine
separate range values for FTP-based city
and HFET-based highway driving, then

calculate a combined value by
arithmetically averaging the two values,
weighted 0.55 and 0.45 respectively,
and round to the nearest whole number.
(ii) Use good engineering judgment to
calculate the vehicle’s operating
distance before the fuel tank is empty
when starting with a full fuel tank and
a fully charged battery, consistent with
the procedure and calculation specified
in paragraph (i)(3)(i) of this section and
the fuel economy values as described in
paragraph (a) of this section.
(j) [Reserved]
(k) Charge time. For electric vehicles,
determine the time it takes to fully
charge the battery from a standard 110
volt power source to the point that the
battery meets the manufacturer’s end-ofcharge criteria, consistent with the
procedures specified in SAE J1634
(incorporated by reference in § 600.011)
for electric vehicles and in SAE J1711
(incorporated by reference in § 600.011)
for plug-in hybrid electric vehicles, as
described in § 600.116. This value may
be more or less than the 12-hour
minimum charging time specified for
testing. You may alternatively specify
the charge time based on a 220 volt
power source if your owners manual
recommends charging with the higher
voltage; you must then identify the
voltage associated with the charge time
on the fuel economy label.
(l) California-specific values. If the
Administrator determines that
automobiles intended for sale in
California are likely to exhibit
significant differences in fuel economy
or other label values from those
intended for sale in other states, the
Administrator will compute separate
values for each class of automobiles for
California and for the other states.

Revisions and Additions to Motor Vehicle Fuel Economy Label
AGENCY: Environmental Protection Agency (EPA) and National Highway
Traffic Safety Administration (NHTSA), Department of Transportation.
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) and the National
Highway Traffic Safety Administration (NHTSA) are conducting a joint
rulemaking to redesign and add information to the current fuel economy
label that is posted on the window sticker of all new cars and light-
duty trucks sold in the U.S. The redesigned label will provide new
information to American consumers about the fuel economy and
consumption, fuel costs, and environmental impacts associated with
purchasing new vehicles beginning with model year 2012 cars and trucks.
This action will also develop new labels for certain advanced
technology vehicles, which are poised to enter the U.S. market, in
particular plug-in hybrid electric vehicles and electric vehicles.
NHTSA and EPA are proposing these changes because the Energy
Independence and Security Act (EISA) of 2007 imposes several new
labeling requirements, because the agencies believe that the current
labels can be improved to help consumers make more informed vehicle
purchase decisions, and because the time is right to develop new labels
for advanced technology vehicles that are being commercialized. This
proposal is also consistent with the recent joint rulemaking by EPA and
NHTSA that established harmonized federal greenhouse gas (GHG)
emissions and corporate average fuel economy (CAFE) standards for new
cars, sport utility vehicles, minivans, and pickup trucks for model
years 2012-2016.
DATES: Comments: Comments must be received on or before November 22,
2010. Under the Paperwork Reduction Act, comments on the information
collection provisions must be received by the Office of Management and
Budget (OMB) on or before October 25, 2010. See the SUPPLEMENTARY
INFORMATION section on ``Public Participation'' for more information
about written comments.
Hearings: NHTSA and EPA will jointly hold two public hearings; one
in Chicago on October 14, 2010, and one in Los Angeles on October 21,
2010, with both daytime and evening sessions at each location. EPA and
NHTSA will announce the specific hearing locations and times of day in
a separate Federal Register announcement. See the SUPPLEMENTARY
INFORMATION section on ``Public Participation'' for more information

B. Public Participation
NHTSA and EPA request comment on all aspects of this joint proposed
rule. This section describes how you can participate in this process.
How do I prepare and submit comments?
In this joint proposal, there are many issues common to both EPA's
and NHTSA's proposals. For the convenience of all parties, comments
submitted to the EPA docket (whether hard copy or electronic) will be
considered comments submitted to both EPA and the NHTSA docket, and
vice versa. Therefore, the public only needs to submit one set of
comments to either one of the two agency dockets that will be reviewed
by both agencies. Comments that are submitted for consideration by only
one agency should be identified as such, and comments that are
submitted for consideration by both agencies should be identified as
such. Absent such identification, each agency will exercise its best
judgment to determine whether a comment is submitted on its proposal.
Further instructions for submitting comments to either the EPA or
NHTSA docket are described below.
EPA: Direct your comments to Docket ID No EPA-HQ-OAR-2009-0865.
EPA's policy is that all comments received will be included in the
public docket without change and may be made available online at https://www.regulations.gov, including any personal information provided,
unless the comment includes information claimed to be Confidential
Business Information (CBI) or other information whose disclosure is
restricted by statute. Do not submit information that you consider to
be CBI or otherwise protected through https://www.regulations.gov or e-
mail. The https://www.regulations.gov Web site is an ``anonymous
access'' system, which means EPA will not know your identity or contact
information unless you provide it in the body of your comment. If you
send an e-mail comment directly to EPA without going through https://www.regulations.gov your e-mail address will be automatically captured
and included as part of the comment that is placed in the public docket
and made available on the Internet. If you submit an electronic
comment, EPA recommends that you include your name and other contact
information in the body of your comment and with any disk or CD-ROM you
submit. If EPA cannot read your comment due to technical difficulties
and cannot contact you for clarification, EPA may not be able to
consider your comment. Electronic files should avoid the use of special
characters, any form of encryption, and be free of any defects or
viruses. For additional information about EPA's public docket visit the
EPA Docket Center homepage at https://www.epa.gov/epahome/dockets.htm.
NHTSA: Your comments must be written and in English. To ensure that
your comments are correctly filed in the docket, please include the
Docket Number NHTSA-2010-0087 in your comments. Your comments must not
be more than 15 pages long.\4\ NHTSA established this limit to
encourage you to write your primary comments in a concise fashion.
However, you may attach necessary additional documents to your
comments. There is no limit on the length of the attachments. If you
are submitting comments electronically as a PDF (Adobe) file, we ask
that the documents submitted be scanned using the Optical Character
Recognition (OCR) process, thus allowing the agency to search and copy
certain portions of your submissions.\5\ Please note that pursuant to
the Data Quality Act, in order for the substantive data to be relied
upon and used by the agencies, it must meet the information quality
standards set forth in the OMB and Department of Transportation (DOT)
Data Quality Act guidelines. Accordingly, we encourage you to consult
the guidelines in preparing your comments. OMB's guidelines may be
accessed at https://www.whitehouse.gov/omb/fedreg_reproducible (last
accessed June 2, 2010), and DOT's guidelines may be accessed at https://regs.dot.gov (last accessed June 22, 2010).
---------------------------------------------------------------------------
\4\ 49 CFR 553.21.
\5\ Optical character recognition (OCR) is the process of
converting an image of text, such as a scanned paper document or
electronic fax file, into computer-editable text.
---------------------------------------------------------------------------
Tips for Preparing Your Comments
When submitting comments, please remember to:
Identify the rulemaking by docket numbers and other
identifying information (subject heading, Federal Register date and
page number).
Follow directions--The agencies may ask you to respond to
specific questions or organize comments by referencing a Code of
Federal
[[Page 58080]]
Regulations (CFR) part or section number.
Explain why you agree or disagree, suggest alternatives,
and substitute language for your requested changes.
Describe any assumptions and provide any technical
information and/or data that you used.
If you estimate potential costs or burdens, explain how
you arrived at your estimate in sufficient detail to allow for it to be
reproduced.
Provide specific examples to illustrate your concerns and
suggest alternatives.
Explain your views as clearly as possible, avoiding the
use of profanity or personal threats.
Make sure to submit your comments by the comment period deadline
identified in the DATES section above.
How do I submit confidential business information?
Any confidential business information (CBI) submitted to one of the
agencies will also be available to the other agency.\6\ However, as
with all public comments, any CBI information only needs to be
submitted to either one of the agencies' dockets, and it will be
available to the other. Following are specific instructions for
submitting CBI to either agency.
---------------------------------------------------------------------------
\6\ This statement constitutes notice to commenters pursuant to
40 CFR 2.209(c) that EPA will share confidential information
received with NHTSA unless commenters specify that they wish to
submit their CBI only to EPA and not to both agencies.
---------------------------------------------------------------------------
EPA: Do not submit CBI to EPA through https://www.regulations.gov or
e-mail. Clearly mark the part or all of the information that you claim
to be CBI. For CBI information in a disk or CD ROM that you mail to
EPA, mark the outside of the disk or CD ROM as CBI and then identify
electronically within the disk or CD ROM the specific information that
is claimed as CBI. In addition to one complete version of the comment
that includes information claimed as CBI, a copy of the comment that
does not contain the information claimed as CBI must be submitted for
inclusion in the public docket. Information so marked will not be
disclosed except in accordance with procedures set forth in 40 CFR part
2. In addition, you should submit a copy from which you have deleted
the claimed confidential business information to the Docket by one of
the methods set forth above.
NHTSA: If you wish to submit any information under a claim of
confidentiality, you should submit three copies of your complete
submission, including the information you claim to be confidential
business information, to the Chief Counsel, NHTSA, at the address given
above under FOR FURTHER INFORMATION CONTACT. When you send a comment
containing confidential business information, you should include a
cover letter setting forth the information specified in our
confidential business information regulation.\7\ In addition, you
should submit a copy from which you have deleted the claimed
confidential business information to the Docket by one of the methods
set forth above.
---------------------------------------------------------------------------
\7\ 49 CFR part 512.
---------------------------------------------------------------------------
Will the agencies consider late comments?
NHTSA and EPA will consider all comments received before the close
of business on the comment closing date indicated above under DATES. To
the extent practicable, we will also consider comments received after
that date. If interested persons believe that any new information the
agency places in the docket affects their comments, they may submit
comments after the closing date concerning how the agency should
consider that information for the final rule. However, the agencies'
ability to consider any such late comments in this rulemaking will be
limited due to the time frame for issuing a final rule.
If a comment is received too late for us to practicably consider it
in developing a final rule, we will consider that comment as an
informal suggestion for future rulemaking action.
How can I read the comments submitted by other people?
You may read the materials placed in the docket for this document
(e.g., the comments submitted in response to this document by other
interested persons) at any time by going to https://www.regulations.gov.
Follow the online instructions for accessing the dockets. You may also
read the materials at the EPA Docket Center or NHTSA Docket Management
Facility by going to the street addresses given above under ADDRESSES.
How do I participate in the public hearings?
NHTSA and EPA will jointly hold two public hearings; one in Chicago
on October 14, 2010, and one in Los Angeles on October 21, 2010, with
both daytime and evening sessions at each location. EPA and NHTSA will
announce the specific hearing locations and times of day in a separate
Federal Register announcement.
If you would like to present testimony at the public hearings, we
ask that you notify the EPA and NHTSA contact persons listed under FOR
FURTHER INFORMATION CONTACT at least ten days before the hearing. Once
EPA and NHTSA learn how many people have registered to speak at the
public hearing, we will allocate an appropriate amount of time to each
participant, allowing time for lunch and necessary breaks throughout
the day. For planning purposes, each speaker should anticipate speaking
for approximately ten minutes, although we may need to adjust the time
for each speaker if there is a large turnout. We suggest that you bring
copies of your statement or other material for the EPA and NHTSA panels
and the audience. It would also be helpful if you send us a copy of
your statement or other materials before the hearing. To accommodate as
many speakers as possible, we prefer that speakers not use
technological aids (e.g., audio-visuals, computer slideshows). However,
if you plan to do so, you must notify the contact persons in the FOR
FURTHER INFORMATION CONTACT section above. You also must make
arrangements to provide your presentation or any other aids to NHTSA
and EPA in advance of the hearing in order to facilitate set-up. In
addition, we will reserve a block of time for anyone else in the
audience who wants to give testimony.
The hearing will be held at a site accessible to individuals with
disabilities. Individuals who require accommodations such as sign
language interpreters should contact the persons listed under FOR
FURTHER INFORMATION CONTACT section above no later than ten days before
the date of the hearing.
NHTSA and EPA will conduct the hearing informally, and technical
rules of evidence will not apply. We will arrange for a written
transcript of the hearing and keep the official record of the hearing
open for 30 days to allow you to submit supplementary information. You
may make arrangements for copies of the transcript directly with the
court reporter.

I. Overview of Joint EPA/NHTSA Proposal on New Vehicle Labels
A. Summary of and Rationale for Proposed Label Changes
This joint action by the Environmental Protection Agency (EPA) and
the National Highway Traffic Safety Administration (NHTSA) proposes
what will likely be the most significant overhaul of the federal
government's fuel economy label or ``sticker'' since its inception over
30 years ago.
The current fuel economy label required on all new passenger cars,
light-duty trucks, and medium-duty passenger vehicles contains the
following core information, as required by statute:
City and highway fuel economy values in miles per gallon.
Comparison of the vehicle's combined city/highway fuel
economy to a range of comparable vehicles.
Estimated fuel cost to operate the vehicle for one year.
This joint proposal is designed to update the current label in
order to increase the usefulness of the label in helping consumers
choose more efficient and environmentally friendly vehicles that would
also meet new requirements added by Congress. This proposal also
includes new label designs for electric vehicles (EVs) and plug-in
hybrid electric vehicles (PHEVs), two advanced vehicle technologies
that are beginning to enter the market.
EPA and NHTSA are co-proposing two label designs for public comment
without a single primary proposal, although the final rule will adopt
only one label design. Both label designs meet statutory requirements
and rely on the same underlying data; they differ in how the data is
used and presented on the label. One is a more traditional label design
that retains the current label's focus on fuel economy values and
annual fuel cost projections, with a general label layout more similar
to the current label. The second label design contains all appropriate
information but prominently features a letter grade to communicate the
overall fuel economy and greenhouse gas emissions--along with projected
5-year fuel cost or savings associated with a particular vehicle when
compared to an average vehicle. The agencies are also seeking comment
on an alternative third label design that follows a more traditional
format but presents some information differently. All labels expand
upon the content found on the current label and include the following
information for conventional vehicles (advanced technology vehicle
labels contain additional information tailored to the individual
technology):
City and highway fuel economy values in miles per gallon.
Combined city/highway fuel consumption in gallons per 100
miles.
Tailpipe carbon dioxide (CO2) emissions in
grams per mile.
Annual fuel cost in dollars per year.
A slider bar comparing the combined fuel economy to all
other vehicles.
A slider bar comparing the CO2 emissions to all
other vehicles.
A slider bar comparing non-CO2 (``other'' or
``smog-related'') emissions to all other vehicles.
A symbol that can be read by a `Smartphone' for additional
consumer information (also known as a QR Code[reg]).
A reference to a Federal government Web site for
additional information.
Despite the fact that the co-proposed labels are based on the same
underlying data, they are significantly different in terms of
presentation and prominence. The agencies encourage public feedback on
the central question of which label design would be more useful and
help consumers select more energy efficient and environmentally
friendly vehicles that meet their needs, or whether the agencies should
consider alternative designs.
NHTSA and EPA are proposing these changes because the Energy
Independence and Security Act (EISA) of 2007 mandates several new
labeling requirements intended to help consumers make more informed
vehicle purchase decisions, and because this is an appropriate time to
develop new labels for advanced technology vehicles (Battery Electric
or EVs and Plug-In Hybrid Vehicles or PHEVs) that are being
commercialized. The agencies believe that a joint label meeting our
separate statutory requirements and our shared consumer information
objectives makes far more sense for both consumers and manufacturers
than separate labels. As a joint rulemaking, this proposal is also
consistent with the recent joint rulemaking by EPA and NHTSA that
established harmonized federal greenhouse gas (GHG) emissions and
corporate average fuel economy (CAFE) standards for new cars, sport
utility vehicles, minivans, and pickup trucks for model years 2012-
2016.\8\
---------------------------------------------------------------------------

---------------------------------------------------------------------------
The agencies believe these new labeling requirements for
automobiles are important in light of a growing national interest in
both fuel economy and climate change. Historically, consumers have
generally paid the most attention to fuel economy when fuel prices
increase sharply over a short period of time, such as in 2008, but the
agencies believe that this phenomenon has changed and consumers will
continue in the future to pay more attention to fuel economy. Based on
projections from the U.S. Energy Information Administration that future
gasoline prices will increase over coming decades due to global
economic growth and oil demand, we believe that it is likely that
consumer interest in and use of the fuel economy label will grow over
time.\9\ In addition, given the increased awareness of consumers
regarding climate change and air pollution, more comprehensive
information on the emissions performance of vehicles, as required by
EISA, could help consumers make more informed decisions on how a
vehicle they buy may impact the environment.

Information Administration, DOE/EIA-0383 (2010), May 11, 2010,

---------------------------------------------------------------------------
It is also important for the agencies to define labeling
requirements for advanced vehicle technologies that are nearing
commercialization. The existing label has long provided city and
highway fuel economy in terms of miles per gallon (MPG) values, which
the agencies believe are well recognized and understood by consumers,
and which are widely used as metrics for comparing the efficiency of
one vehicle to another. Since the late 1970s when the fuel economy
label was first established by EPA as required under the Energy Policy
Conservation Act (EPCA) of 1975, over 99 percent of the automobiles
sold have been conventional, internal-combustion engine vehicles that
run on petroleum-based fuels (or a liquid fuel blend dominated by
petroleum). When manufacturers produced different advanced technology
vehicles, such as compressed natural gas vehicles, EPA has generally
addressed the need for labels on a case-by-case basis.
[[Page 58083]]
Over the next several model years, however, the agencies expect to
see increasing numbers of EVs and PHEVs entering the marketplace. This
proposal includes changes to the label to address some of the specific
issues raised by the use of grid electricity as a fuel for EVs and
PHEVs. These vehicles will be required to display labels containing the
same kind of information as conventional vehicles, but some of that
information may be better conveyed in different ways, and consumers may
be interested in different information for these vehicles. For example,
evaluating the performance of a vehicle that uses grid electricity as
some or all of its fuel, or the cost of operating such a vehicle,
presents unique challenges for making an informed comparison between
different EVs and PHEVs, and between advanced technology vehicles and
their conventional vehicle counterparts including gasoline and diesel
fueled vehicles and hybrid gasoline electric vehicles (HEVs).
The co-proposed label designs present two approaches for addressing
the complex challenges associated with labels for these advanced
technology vehicles, and the agencies encourage the public to comment
on a wide range of possible solutions. The agencies recognize that this
is only the first generation of EV and PHEV labels, and we expect to
refine them over time as we have done with conventional vehicle labels.
Additionally, the agencies recognize that other advanced technology
vehicles, such as fuel cell vehicles (FCVs), may enter the marketplace
in the near future as well, but for purposes of this first effort we
have chosen to focus on EVs and PHEVs. Specific label requirements for
other advanced technology vehicles will be developed at a later time as
those vehicles enter the market.
This joint proposal is designed to satisfy each agency's statutory
responsibilities in a manner that maximizes usefulness for the
consumer, while avoiding unnecessary burden on the manufacturers who
prepare the vehicle labels. Since 1977, EPA has required auto
manufacturers to label all new automobiles,\10\ pursuant to EPCA.\11\
As amended, EPCA requires that labels shall contain the following
information:
---------------------------------------------------------------------------
\10\ An ``automobile'' is defined for these purposes as a ``4-
wheeled vehicle that is propelled by fuel, or by alternative fuel,
manufactured primarily for use on public streets, roads, and
highways'' and ``rated at not more than 8,500 pounds gross vehicle
weight.'' See 49 U.S.C. 32901(a)(3) and 32908(a)(1).
\11\ Public Law 94-163.
---------------------------------------------------------------------------
(1) The fuel economy of the automobile;
(2) The estimated annual fuel cost of operating the automobile;
(3) The range of fuel economy of comparable vehicles of all
manufacturers;
(4) A statement that a booklet is available from the dealer to
assist in making a comparison of fuel economy of other automobiles
manufactured by all manufacturers in that model year;
(5) The amount of the automobile fuel efficiency tax (``gas guzzler
tax'') imposed on the sale of the automobile under section 4064 of the
Internal Revenue Code of 1986 (26 U.S.C. 4064); and
(6) Other information required or authorized by the EPA
Administrator that is related to the information required by (1)
through (4) above.\12\
---------------------------------------------------------------------------
\12\ 49 U.S.C. 32908(b).
---------------------------------------------------------------------------
In the Energy Independence and Security Act of 2007 (EISA),\13\
Congress required that NHTSA, in consultation with EPA and the
Department of Energy (DOE), establish regulations to implement several
new labeling requirements for new automobiles.\14\ NHTSA must develop a
program that requires manufacturers to label new automobiles with
information reflecting an automobile's performance with respect to fuel
economy and greenhouse gas and other emissions over the useful life of
the automobile based on criteria provided by EPA.\15\ NHTSA must also
develop a rating system that makes it easy for consumers to compare the
fuel economy and greenhouse gas and other emissions of automobiles at
the point of purchase, including designations of automobiles with the
lowest GHG emissions over the useful life of the vehicles, and the
highest fuel economy.\16\
---------------------------------------------------------------------------
\13\ Public Law 110-140.
\14\ EISA Sec. 108, codified at 49 U.S.C. 32908(g).
\15\ 49 U.S.C. 32908(g)(1)(a)(i).
\16\ 49 U.S.C. 32908(g)(1)(a)(ii).
---------------------------------------------------------------------------
Thus, either the basic label for automobiles needs to be expanded
to include additional information on performance in terms of fuel
economy, greenhouse gas and other emissions, or a new label needs to be
required. NHTSA and EPA believe that a joint rulemaking to combine all
of these elements into a single revised fuel economy label is the most
appropriate way to meet the goals described above, rather than placing
the information in two separate labels with duplicative and overlapping
information, which could cause consumer confusion and impose
unnecessary burden on the manufacturers.\17\
---------------------------------------------------------------------------
\17\ The agencies also raised the issue of the upcoming labeling
requirements in the recent joint rulemaking for MYs 2012-2016 CAFE
and GHG standards for light-duty vehicles, 75 FR 25324 (May 7,
2010).
---------------------------------------------------------------------------
Finally, given the goals described above and the need to provide
additional information on the label, the agencies believe that the
overall vehicle label design format and content should be reevaluated
and could be improved. Simply including the additional information
required under EISA for both conventional and advanced technology
vehicles necessitates a review of the overall label design.
As described above, the agencies view the purpose of the label as
providing information that will be most useful for consumers in making
informed decisions regarding the energy efficiency and emissions
impacts of the vehicles they purchase. Providing information on energy,
environmental performance, and cost can educate consumers in various
ways. These metrics have the potential to help people who value this
kind of information to make a more informed choice among different
vehicles. It also has the potential to inform people who currently
place less or even no value on this kind of information, but who may
decide it is more important to them at some point in the future. NHTSA
and EPA are mindful that this is a complicated issue and that there is
no readily ascertainable metric to determine whether we have achieved
this somewhat subjective and qualitative purpose. Therefore, EPA and
NHTSA are co-proposing two options, and also taking comment on another
alternative, that highlight a number of relevant issues on which we
seek public comment. The agencies will consider all public comments and
publish a final rule in the near future.
B. A Comprehensive Research Program Informed the Development of
Proposed Labels
Since today's proposal includes adding important new elements to
the existing label as well as creating new labels for advanced
technology vehicles, EPA and NHTSA embarked on a comprehensive and
innovative research program beginning in the fall of 2009. The research
helped inform the development of the new labels being proposed and
included three phases of consumer focus groups, a review of available
literature, and a day-long consultation with an expert panel of
individuals who have introduced new products or have spearheaded
national educational campaigns.
For the focus groups, the agencies decided to use a three-phase
approach
[[Page 58084]]
in order to accommodate the sheer amount of information intended to be
covered in the groups, as well as to use each phase to inform the next
phase to help evolve the overall label design in regard to both content
and appearance. Focus groups were held beginning in late February
through May 2010 in four cities: Charlotte, Houston, Chicago, and
Seattle. Overall, 32 focus groups were convened with a total of 256
participants. We asked the focus groups about the following issues:
How they use the current fuel economy label,
What feedback they could give us on potential new
information and metrics for the label for conventional and advanced
technology vehicles (EVs and PHEVs), and
What feedback they could give us, after reviewing draft
labels, on designs and the level of information that makes sense, as
well as overall preference for displaying information.
The insights received from the focus groups were key for the
agencies with regard to individual metrics that consumers wanted to see
on labels and also with regard to effective label designs. Overall,
focus groups indicated \18\ that redesigned labels must:

August 2010 ; and Environmental Protection Agency Fuel Economy
Label: Phase 3 Focus Groups, EPA420-R-10-905, August 2010.
---------------------------------------------------------------------------
Create an immediate first impression for consumers.
Be easy to read and understand quickly.
Clearly identify vehicle technology (conventional, EV,
PHEV).
Utilize color.
Chunk information to allow people to deal with ``more
information.''
Be consistent in content and design across technologies.
Allow for comparison across technologies.
Make it easy to identify the most fuel efficient and
environmentally friendly vehicles.
Following the focus group research, we assembled an expert panel
for a one day consultation and asked them to give us feedback on the
draft label designs the focus groups had helped create and to also
assist us in identifying opportunities and strategies to provide more
and better information to consumers so that they can more easily assess
the costs, emissions, and energy efficiency of different vehicles. The
experts came from a variety of fields in advertising and product
development, and were chosen because they have led successful national
efforts to introduce new products or have spearheaded national
educational campaigns. After viewing the draft labels, the expert panel
offered the agencies the following insights and guidance \19\ that were
key in developing one of the co-proposed label designs, including:
---------------------------------------------------------------------------
\19\ Environmental Protection Agency Fuel Economy Label: Expert
Panel Report, EPA420-R-10-908, August 2010.
---------------------------------------------------------------------------
Keep it simple; we yearn for simplicity (fewer, bigger,
better).
Consumers don't act on details.
Remember the reality of very short label viewing time--
roll ratings and metrics up into a single score.
Use cost savings information- a very strong consumer
motivator.
Develop a Web site that would be launched in conjunction
with the new label. This consumer-focused, user friendly Web site would
provide more specific information on the label including additional
information on the letter grade, along with access to the tools,
applications, and social media.
Beyond these two core research elements, the agencies also
undertook a comprehensive literature review \20\ and drafted and had
peer reviewed an internet survey. The agencies intend to administer the
survey concurrently with the release of this proposal, and the results
will be made publicly available in the dockets for this proposal prior
to issuing a final rule with the new label requirements.

Literature Review, EPA420-R-10-906, August 2010.
---------------------------------------------------------------------------
The agencies also met with a number of stakeholders, including
environmental organizations, auto manufacturers, and dealers, to gather
their input on what the label should and should not contain, as well as
to ascertain particular concerns.\21\ Comments received on labeling
issues in the context of the joint rulemaking on fuel economy and GHG
standards,\22\ as well as for the 2006 fuel economy labeling rule,\23\
have also been considered.
---------------------------------------------------------------------------
\21\ Pursuant to DOT Order 2100.2, NHTSA will place a memorandum
recording those meetings it attended, and attach documents submitted
by stakeholders, as appropriate, when the information received
formed a basis for this proposal, and the information can be made
public, in the docket for this rulemaking.

2009-0472.
\23\ Available at Docket No. EPA-HQ-OAR-2005-0169.
---------------------------------------------------------------------------
C. When would the proposed label changes take effect?
The agencies propose that the final label changes will take effect
for model year (MY) 2012 vehicles, consistent with the recent joint
rulemaking by EPA and NHTSA that established harmonized federal GHG
emissions and CAFE standards for new cars, sport utility vehicles,
minivans, and pickup trucks for model years 2012 through 2016.\24\ For
those advanced technology vehicles that will be introduced to the
market prior to MY2012, EPA will work with individual manufacturers on
a case-by-case basis to develop interim labels under EPA's current
regulations that can be used prior to MY2012 and that are consistent
with the proposed labels for advanced technology vehicles.
---------------------------------------------------------------------------
\24\ 75 FR 25324, May 7, 2010.
---------------------------------------------------------------------------
D. What are the estimated costs and benefits of the proposed label
changes?
The primary costs associated with this proposed rule come from
revisions to the fuel economy label and new testing requirements. As
discussed in Section VII of this preamble, we estimate that the costs
of this rule are likely to be in the range of $649,000--$2.8 million
per year. This rule is not economically significant under Executive
Order 12866 or any DOT or EPA policies and procedures because it does
not exceed $100 million or meet other related standards.
The primary benefits associated with this proposed rule come from
any improvements in consumer decision-making that may lead to reduced
vehicle and fuel costs for them. There may be additional effects on
criteria pollutants and greenhouse gas emissions. At this time, EPA and
NHTSA do not believe it is feasible to fully develop a complete
benefits analysis of the potential benefits.
EPA and NHTSA request comment on the assessment of the benefits and
costs presented in Section VII below.
E. Relationship of This Proposal to Other Federal and State Programs
This proposal involves the addition of new information and design
changes to conventional vehicle labels and the creation of specific
labels for certain advanced vehicle technologies, but will not impact
other important elements of the Federal government's fuel economy and
GHG emissions regulatory programs. For example, this proposal will not
affect the fuel economy compliance values used in NHTSA's CAFE program,
or the GHG emissions compliance values used in EPA's GHG emissions
control program. Nor will this proposal affect the methodology by which
EPA generates the consumer fuel economy values used on the vehicle
labels and provided at https://
[[Page 58085]]
www.fueleconomy.gov. The result of the additional information,
including environmental information, appearing on the label will
necessitate that additional information also be displayed on this Web
site in the future. Finally, this proposal does not affect the test
procedures that are used by EPA and manufacturers to generate the
Federal government's vehicle fuel economy and GHG emissions database.
This proposal also does not affect the vehicle labels required by
the California Air Resources Board which indicate relative ratings for
``Smog'' and ``Global Warming,'' in fulfillment of that state's
statutory requirements. The agencies are aware that the California
labels provide information that is effectively duplicative with some of
the information on the labels that will result from this rulemaking
effort, although using different underlying rating methodologies and
presentational approaches. It is the hope of both NHTSA and EPA that
the Federal label can meet the CARB requirements and, thus, preclude
the need for a separate set of labels. However, it is ultimately up to
California to determine how to implement its statute and, thus, beyond
the purview of this rulemaking to make any such determination.
F. History of Federal Fuel Economy Label Requirements
The fuel economy label has evolved several times since it was first
required by Congress in the 1970s, both in response to new statutory
requirements and to changing policy objectives. There have been
important changes in the past to make the label more technically
accurate and understandable to consumers. The changes being proposed
are consistent with past efforts by EPA to make the fuel economy label
more consumer friendly and effective over time. This section provides a
brief historical summary of the development of the fuel economy label.
The Energy Policy and Conservation Act of 1975 (EPCA) established
two primary fuel economy requirements: (1) Fuel economy information,
designed for public use, in the form of fuel economy labels posted on
all new motor vehicles, and the publication of an annual booklet of
fuel economy information to be made available free to the public by car
dealers; and (2) calculation of a manufacturer's average fuel economy
and compliance with a standard (later, this compliance program became
known as the Corporate Average Fuel Economy (CAFE) program). The
responsibilities for these requirements were split between EPA, the
Department of Transportation (DOT) \25\ and the Department of Energy
(DOE). EPA is responsible for establishing the test methods and
procedures both for determining the fuel economy estimates that are
displayed on the labels and in the annual booklet, and for the
calculation of a manufacturer's corporate average fuel economy. DOT,
and by delegation, NHTSA, is responsible for administering the CAFE
compliance program, which includes establishing standards, determining
compliance, and assessing any penalties as needed. DOE is responsible
for publishing and distributing the annual fuel economy information
booklet.
---------------------------------------------------------------------------
\25\ The CAFE-related responsibilities of the Secretary of
Transportation are delegated to the NHTSA Administrator at 49 CFR
1.50.
---------------------------------------------------------------------------
EPA published regulations implementing portions of the EPCA statute
in 1976.\26\ The provisions in this regulation, effective with the 1977
model year, established the first fuel economy label along with the
procedures to calculate fuel economy values for labeling and CAFE
purposes that used the Federal Test Procedure (FTP or ``city'' test)
and the Highway Fuel Economy Test (HFET or ``highway'' test) data as
the basis for the calculations. At that time, the fundamental process
for determining fuel economy was the same for labeling as for CAFE,
except that the CAFE calculations combined the city and highway fuel
economy values into a single number for manufacturers' compliance
purposes.\27\
---------------------------------------------------------------------------
\26\ 41 FR 38685, promulgated at 40 CFR part 600.
\27\ EPCA requires that manufacturers simply comply with
passenger car and light truck CAFE standards, it does not require
separate city and highway standards for each type of automobile.
Thus, EPA calculates the average fuel economy for a manufacturer by
weighting and combining the results of each automobile on the
separate city and highway cycles. See 49 U.S.C. 32904(c).
---------------------------------------------------------------------------
After a few years of public exposure to the fuel economy estimates
on the labels of new vehicles, it soon became apparent that drivers
were disappointed by not often achieving these estimates on the road
and expected them to be as accurate as possible. In 1978, Congress
recognized the concern about differences between EPA-estimated fuel
economy values and actual consumer experience and mandated a study
under section 404 of the National Energy Conservation Policy Act of
1978.\28\ In February 1980, a set of hearings were conducted by the
U.S. House of Representatives Subcommittee on Environment, Energy, and
National Resources. One of the recommendations in the subsequent report
by the Subcommittee was that ``EPA devise a new MPG system for labeling
new cars and for the Gas Mileage Guide that provides fuel economy
values, or a range of values, that most drivers can reasonably expect
to experience.'' \29\

Economy: EPA's Performance,'' Report 96-948, May 13, 1980.
---------------------------------------------------------------------------
EPA commenced a rulemaking process in 1980 to revise its fuel
economy labeling procedures, and analyzed a vast amount of in-use fuel
economy data as part of that rulemaking.\30\ In 1984, EPA published new
fuel economy labeling procedures that were applicable to 1985 and later
model year vehicles.\31\ The decision was made to retain the FTP and
highway test procedures, primarily because those procedures were also
used for other purposes, including emissions certification and CAFE
determination. Based on the in-use fuel economy data, however, it was
evident that the final fuel economy values put on the labels needed to
be adjusted downward in order to reflect more accurately consumers'
average fuel economy experience. The final rule, therefore, included
downward adjustment factors for both the city and highway label fuel
economy estimates. The city values (based on the raw FTP test data)
were adjusted downward by 10 percent and the highway values (likewise
based on the raw highway test data) were adjusted downward by 22
percent.\32\

---------------------------------------------------------------------------
In the early 2000s, EPA again began investigating the accuracy of
the fuel economy label estimates, and concluded that driving behavior
(e.g., higher average speed and acceleration) and other factors (such
as the use of ethanol as a gasoline blending agent) had changed
significantly since the correction factors were implemented in 1985,
leading again to a widening gap between real-world fuel economy and the
label estimates that consumers saw when shopping for new vehicles.
During the development of vehicle emissions regulations in the late
1990s, EPA had already conclusively found that the city and highway
tests did not adequately represent real-world driving, and in December
of 2006 EPA finalized new
[[Page 58086]]
test methods for calculating the fuel economy label values.\33\
---------------------------------------------------------------------------
\33\ 71 FR 77872, December 27, 2006.
---------------------------------------------------------------------------
The 2006 final rule made three important changes. First, EPA's new
methods brought the miles per gallon estimates closer to consumers'
actual fuel economy by including factors such as high speeds, quicker
accelerations, air conditioning use, and driving in cold temperatures.
These revised fuel economy estimates also reflect other conditions that
influence fuel economy, like road grade, wind, tire pressure, load, and
the effects of different fuel properties. The new estimates took effect
with model year 2008 vehicles. Second, EPA now requires fuel economy
labels on certain heavier vehicles up to 10,000 pounds gross vehicle
weight, such as larger SUVs and vans. Manufacturers will be required to
post fuel economy labels on these vehicles beginning with the 2011
model year. Third, to convey fuel economy information to the public
more effectively, EPA updated the design and content of the label. The
rule required that new labels be placed on vehicles manufactured after
September 1, 2007. The fuel economy for each vehicle model continues to
be presented to consumers on the label as city and highway MPG
estimates.
G. Statutory Provisions and Legal Authority
1. Energy Policy and Conservation Act (EPCA)
Under EPCA, EPA is responsible for developing the fuel economy
labels that are posted on all new light duty cars and trucks sold in
the U.S. and beginning in MY 2011 all new medium duty trucks as well.
Medium-duty passenger vehicles are a subset of vehicles between 8,500
and 10,000 pounds gross vehicle weight that includes large sport
utility vehicles and vans, but not pickup trucks. EPCA requires the
manufacturers of automobiles to attach the fuel economy label in a
prominent place on each automobile manufactured in a model year and
also requires auto dealerships to maintain the label on the
automobile.\34\
---------------------------------------------------------------------------
\34\ 49 U.S.C. 32908(b)(1).
---------------------------------------------------------------------------
EPCA specifies the information that is minimally required on every
fuel economy label.\35\ As stated above, labels must include:
---------------------------------------------------------------------------
\35\ 49 U.S.C. 32908(b)(2)(A) through (F).
---------------------------------------------------------------------------
The fuel economy of the automobile,
The estimated annual fuel cost of operating the
automobile.
The range of fuel economy of comparable automobiles of all
manufacturers,
