SUPPLEMENTARY INFORMATION: I. Introduction NHTSA has been issuing Corporate Average Fuel Economy (CAFE) standards since the late 1970's 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 thus 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. NHTSA will determine, based on all of the relevant circumstances, whether that calls for establishing standards that reach the 35 mpg goal earlier than MY 2020. EISA also mandated that the CAFE standards be based on one or more vehicle attribute. For example, size-based (
                    *i.e.*, size-indexed) standards assign higher fuel economy targets to smaller vehicles and lower ones to larger vehicles. The fleet wide 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 technologies across a broad range of their passenger car and light truck fleets. NHTSA proposed in April 2008 to begin implementing EISA by establishing CAFE standards for MYs 2011-2015. In a January 26, 2009 memorandum, the President requested NHTSA to divide its rulemaking into two parts. First, he requested that the agency issue a final rule adopting CAFE standards for MY 2011 only, and do so by March 30, 2009 in order to comply with EPCA, which requires that a final rule establishing fuel economy standards for a model year be adopted at least 18 months before the beginning of the model year (49 U.S.C. 32902(a)). The agency is working to issue a final rule for MY 2011 in accordance with that schedule. Second, the President requested that NHTSA establish standards for MY 2012 and later after considering the appropriate legal factors, the comments filed in response to the May 2008 proposal, the relevant technological and scientific considerations, and, to the extent feasible, a forthcoming report by the National Academy of Sciences, mandated under section 107 of EISA, assessing the costs and effectiveness of existing and potential automotive technologies that can practicably used to improve fuel economy.[1] To assist the agency in analyzing potential CAFE standards for MYs 2012 through 2016, NHTSA is requesting updated future product plans from 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. NHTSA requests information for MYs 2008-2020 to aid NHTSA in developing a realistic forecast of the MY 2012-2016 vehicle market. 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 helps 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 upcoming CAFE rulemaking, 
                    ( print page 9187)
                    either as part of the basis for the proposed 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. Additionally, the agency notes that, in connection with recent deliberations regarding federal assistance to the industry, some manufacturers submitted short business plans to Congress in December 2008 [2]
                    
                     and restructuring plans to the Treasury Department in February 2009,[3]
                    
                     and that some statements in these plans suggest that manufacturers' product plans may have changed considerably since NHTSA last received detailed confidential product plans in July 2008. In light of these statements, and in light of the current uncertainty surrounding the auto industry, NHTSA will closely review the product plans submitted in response to today's request. We will carefully assess any significant apparent discrepancies between submitted product plans and manufacturers' public statements. 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. Peter Feather at 
                    *peter.feather@dot.gov.*
                     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 practices in this area. II.

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 2008-2020, provide the following information on new technology 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 averaged over the model; (iii) The basis for your answer to (ii) (

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.[6]
                    
                     The agency is also asking that the RPE markup factor (used to determine the RPE cost estimates) is stated in the response. 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 
                    ( print page 9192)
                    Vehicle (EV), Fuel Cell Vehicle, 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 [7]
                    
                     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 single model year, so the agency requests information on possible constraints on the rates at which each technology can penetrate a manufacturer's fleet. Tables IV-3a, b and IV-4a, b with estimates for incremental RPE costs (in 2009 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 [8]
                    
                     that can occur when multiple technologies are applied. 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 2009 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.

                         This information is sought in order to account for a given vehicle model's fuel economy as partitioned into nine energy loss mechanisms. The agency may use this information to estimate the extent to which a given technology reduces losses in each mechanism. Back to Citation

                         “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 “learning 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 rate discount applied with a 300,000 unit threshold would reduce the applicable technology's incremental cost by up to 36 percent. Back to Citation

                         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. Back to Citation

                        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).
