SUPPLEMENTARY INFORMATION:
I. Introduction
NHTSA has been issuing Corporate Average Fuel Economy (CAFE)
standards for the last 30 years under the Energy Policy and
Conservation Act (EPCA). The CAFE program conserves petroleum, a non-
renewable energy source, saves consumers money, and promotes energy
independence and security by reducing dependence on foreign oil. It
also reduces carbon dioxide (CO2) emissions from the
tailpipes of new motor vehicles and the effects of climate change.
The Energy Independence and Security Act (EISA) amended EPCA by
mandating that model year (MY) 2011-2020 standards be set to ensure
that the industry wide average of all new passenger cars and light
trucks, combined, is at least 35 miles per gallon (mpg) by MY 2020.
This is a minimum requirement, as NHTSA must set standards at the
maximum feasible level in each model year. EISA also mandated that the
CAFE standards be based on one or more vehicle attributes. For example,
size-based (i.e., size-indexed) standards assign higher fuel economy
targets to smaller vehicles and lower ones to larger vehicles. The
fleetwide average fuel economy that a particular manufacturer must
achieve depends on the size mix of its fleet. This approach ensures
that all manufacturers will be required to incorporate fuel-saving
[[Page 48193]]
technologies across a broad range of their passenger car and light
truck fleets.
Concurrently with this request for information, the agency is
issuing a joint Notice of Proposed Rulemaking with EPA to propose CAFE
and GHG standards for MYs 2012-2016 passenger cars and light trucks.
The joint proposed rulemaking is consistent with the National Fuel
Efficiency Policy announced by President Obama on May 19, 2009,
responding to the country's critical need to address global climate
change and to reduce oil consumption. The standards proposed by the
agencies require passenger cars and light trucks to meet an estimated
combined average emissions level of 250 grams of CO2 per
mile in MY 2016 under EPA's GHG program, and 34.1 mpg in MY 2016 under
NHTSA's CAFE program and represent a harmonized and consistent national
program (National Program). Under the National Program, automobile
manufacturers would be able to build a single light-duty national fleet
that satisfies all requirements under both programs while ensuring that
consumers still have a full range of vehicle choices.
To assist the agency in analyzing potential CAFE standards for MYs
2012 through 2016, NHTSA is requesting any updates to future product
plans previously provided by vehicle manufacturers, as well as
production data through the recent past, including data about engines
and transmissions for MY 2008 through MY 2020 passenger cars and light
trucks and the assumptions underlying those plans. If manufacturers
have not previously submitted product plan information to NHTSA and
wish to do so, NHTSA also requests such information from them. NHTSA
requests information for MYs 2008-2020 to supplement other information
used by NHTSA in developing a realistic forecast of the MY 2012-2016
vehicle market, and in evaluating what technologies may feasibly be
applied by manufacturers to achieve compliance with the MY 2012-2016
standards. Information regarding earlier model years may help the
agency to better account for cumulative effects such as volume- and
time-based reductions in costs, and also may help to reveal product mix
and technology application trends during model years for which the
agency is currently receiving actual CAFE compliance data. Information
regarding later model years may help the agency gain a better
understanding of how manufacturers' plans through MY 2016 relate to
their longer-term expectations regarding EISA requirements, market
trends, and prospects for more advanced technologies (such as HCCI
engines, and plug-in hybrid, electric, and fuel cell vehicles, among
others). NHTSA will also consider information from model years before
and after MYs 2012-2016 when reviewing manufacturers' planned schedules
for redesigning and freshening their products, in order to examine how
manufacturers anticipate tying technology introduction to product
design schedules. In addition, the agency is requesting information
regarding manufacturers' estimates of the future vehicle population,
and fuel economy improvements and incremental costs attributed to
technologies reflected in those plans. The request for information is
detailed in appendices to this notice. NHTSA has also included a number
of questions directed primarily toward vehicle manufacturers. They can
be found in Appendix A to this notice. Answers to those questions will
assist the agency in its analysis.
Given the importance that responses to this request for comment may
have in NHTSA's final CAFE rulemaking, either as part of the basis for
the standards or as an independent check on them, NHTSA intends to
review carefully and critically all data provided by commenters. It is
crucial that commenters fully respond to each question, particularly by
providing information regarding the basis for technology costs and
effectiveness estimates.
To facilitate the submission of comments and to help ensure the
conformity of data received regarding manufacturers' product plans from
MY 2008 through MY 2020, NHTSA has developed spreadsheet templates for
manufacturers' use. The uniformity provided by these spreadsheets is
intended to aid and expedite our review, integration, and analysis of
the information provided. These templates are the agency's strongly
preferred format for data submittal, and can be found on the Volpe
National Transportation Systems Center (Volpe Center) Web site at ftp://ftpserver.volpe.dot.gov/pub/CAFE/templates/or can be requested from
Mr. Ken Katz at [email protected]. The templates include an automated
tool (i.e., a macro) that performs some auditing to identify missing or
potentially erroneous entries. The appendices to this document also
include sample tables that manufacturers may refer to when submitting
their data to the agency.
In addition, NHTSA would like to note that we will share the
information submitted in response to this notice with the Environmental
Protection Agency (EPA). This sharing will facilitate our consideration
of the appropriate factors to be used in establishing fuel economy
standards for MY 2012 and beyond. We will ensure that confidential
information that is shared is protected from disclosure in accordance
with NHTSA's regulations and practices in this area.

IV. Technologies, Cost and Potential Fuel Economy Improvements
Spreadsheet templates for the tables mentioned in the following
section can be found at ftp://ftpserver.volpe.dot.gov/pub/cafe/
templates/.
1. The agency requests that manufacturers, for each passenger
car and light truck model projected to be manufactured by respondent
between MY 2009-2020, provide the following information on new
technology, including A/C technologies that will be eligible under
EPA's proposed GHG standards, applications:
(i) Description of the nature of the technological improvement;
including the vehicle's baseline technology that the technology
replaces (e.g., 6-speed automatic transmission replacing a 4-speed
automatic transmission)
(ii) The percent fuel economy improvement or the g/mile
CO2 equivalent reduction for A/C technologies, averaged
over the model; please indicate if the weight saving (or increase),
associated with the implementation of the technology, is accounted
for in the fuel economy improvement estimate.
(iii) The basis for your answer to (ii), (e.g., data from
dynamometer tests conducted by respondent, engineering analysis,
computer simulation, reports of test by others);
(iv) The incremental RPE cost (in 2007 dollars), averaged over
the model, associated with implementing the new technology;
(v) The percent production implementation rate and the reasons
limiting the implementation rate
In regards to costs, the agency is requesting information on
cost reductions available through learning effects that are
anticipated, so information should be provided regarding what the
learning effects are, when and at what production volumes they
occur, and to what degrees such learning is expected to be
available.\3\ The agency is also asking that the RPE markup factor
(used to determine the RPE cost estimates) is stated in the
response.
---------------------------------------------------------------------------
\3\ ``Learning effects'' describes the reduction in unit
production costs as a function of accumulated production volume and
small redesigns that reduce costs. Applying learning effects, or
``curves,'' requires estimates of three parameters: (1) The initial
production volume that must be reached before cost reductions begin
to be realized (referred to as ``threshold volume''); (2) the
percent reduction in average unit cost that results from each
successive doubling of cumulative production volume (usually
referred to as the ``learning rate''); and (3) the initial cost of
the technology. The method applies this effect for up to two
doublings of production volume. For example, a 20 percent learning
effect would be applied once at the 300,000 unit threshold volume
and an additional 20 percent learning would be applied at a volume
of 600,000, resulting in total reduction cost of 36 percent.
---------------------------------------------------------------------------
2. Additionally, the agency requests that manufactures and other
interested parties provide the same information, as requested above,
for the technologies listed in the following tables and any other
potential technologies that may be implemented to improve fuel
economy. These potential technologies can be inserted into
additional rows at the end of each table. Examples of other
potential technologies could include but are not limited to:
Homogenous Charge Compression Ignition (HCCI), Electric Vehicle
(EV), Fuel Cell Vehicle and Belt Mounted Integrated Starter
Generator (BISG) and Crank Mounted Integrated Starter Generator
(CISG) specific technologies. In an effort to standardize the
information received the agency requests that if possible
respondents fill in the following tables:
Table IV-1 with estimates of the model year of availability for
each technology listed and any other identified technology.
Table IV-2 with estimated phase-in rates \4\ by year for each
technology listed and any other additional technologies.
Engineering, planning and financial constraints can prohibit many
technologies from being applied across an entire fleet of vehicles
within a year, so the agency requests information on possible
constraints on the rates at which each technology can penetrate a
manufacturer's fleet.
---------------------------------------------------------------------------
\4\ In NHTSA's 2006 rulemaking establishing CAFE standards for
MY 2008-2011 light trucks, the agency considered phase-in caps by
ceasing to add a given technology to a manufacturer's fleet in a
specific model year once it has increased the corresponding
penetration rate by at least the amount of the cap. Having done so,
it applied other technologies in lieu of the ``capped'' technology.
---------------------------------------------------------------------------
Tables IV-3a, b and IV-4a, b with estimates for incremental RPE
costs (in 2007 dollars) and incremental fuel consumption reductions
for each technology listed and any other additional technologies.
These estimates, for the technologies already listed, should assume
that the preceding technologies, as defined by the decision trees in
Appendix B, have already been applied and/or will be superseded. The
agency is requesting that respondents fill in incremental RPE costs
and fuel consumption reductions estimates for all vehicle subclasses
listed. If a respondent feels that the incremental RPE cost and fuel
consumption reduction estimates are similar for different subclasses
they may combine subclasses.
Table IV-5 with estimates for the percentage by which each
technology reduces energy losses attributable to each of nine energy
loss mechanisms.
Tables IV-6a, b with estimates for synergies \5\ that can occur
when multiple technologies are applied.
---------------------------------------------------------------------------
\5\ When two or more technologies are added to a particular
vehicle model to improve its fuel efficiency, the resultant fuel
consumption reduction may sometimes be higher or lower than the
product of the individual effectiveness values for those items. This
may occur because one or more technologies applied to the same
vehicle partially address the same source or sources of engine or
vehicle losses. Alternately, this effect may be seen when one
technology shifts the engine operating points, and therefore
increases or reduces the fuel consumption reduction achieved by
another technology or set of technologies. The difference between
the observed fuel consumption reduction associated with a set of
technologies and the product of the individual effectiveness values
in that set is sometimes referred to as a ``synergy.'' Synergies may
be positive (increased fuel consumption reduction compared to the
product of the individual effects) or negative (decreased fuel
consumption reduction).
---------------------------------------------------------------------------
[[Page 48199]]
3. The agency also asks that manufacturers or other interested
parties provide information on appropriate sequencing of
technologies, so that accumulated cost and fuel consumption effects
may be evaluated incrementally. As examples of possible technology
sequences, ``decision trees'' are shown in Appendix B below.
4. For each new or redesigned vehicle identified in response to
Question III-3 and each new engine or fuel economy improvement
identified in your response to Questions IV-1 and IV-2 provide your
best estimate of the following, in terms of constant 2007 dollars:
A. Total capital costs required to implement the new/redesigned
model or improvement according to the implementation schedules
specified in your response. Subdivide the capital costs into
tooling, facilities, launch, and engineering costs.
B. The maximum production capacity, expressed in units of
capacity per year, associated with the capital expenditure in (a)
above. Specify the number of production shifts on which your
response is based and define ``maximum capacity'' as used in your
answer.
C. The actual capacity that is planned to be used each year for
each new/redesigned model or fuel economy improvement.
D. The increase in variable costs per affected unit, based on
the production volume specified in (b) above.
E. The equivalent retail price increase per affected vehicle for
each new/redesigned model or improvement. Provide an example
describing methodology used to determine the equivalent retail price
increase.
