National Acaclemy of Sciences National Acaclemy of Engineering Institute of Meclicine National Research Council The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Bruce M. Alberts is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engi- neers. Dr. Wm. A. Wulf is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Kenneth I. Shine is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy's purposes of furthering knowledge and advis- ing the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineer- ing communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M. Alberts and Dr. Wm. A. Wulf are chairman and vice chairman, respectively, of the National Research Council.

Acknowledgments The Committee on the Effectiveness and Impact of Cor- porate Average Fuel Economy (CAFE) Standards was aided by the following consultants: Tom Austin, Sierra Research, Inc.; K.G. Duleep, Energy and Environmental Analysis, Inc.; and Steve Plotkin, Argonne National Laboratory. These con- sultants provided analyses to the committee, which the com- mittee used in addition to the many other sources of infor- mation it received. This report has been reviewed by individuals chosen for their diverse perspectives and technical expertise, in accor- dance with procedures approved by the Report Review Com- mittee of the National Research Council (NRC). The pur- pose of this independent review is to provide candid and critical comments that will assist the authors and the NRC in making the published report as sound as possible and to en- sure that the report meets institutional standards for objec- tivity, evidence, and responsiveness to the study charge. The content of the review comments and draft manuscript re- main confidential to protect the integrity of the deliberative process. We wish to thank the following individuals for their participation in the review of this report: William Agnew (NAB), General Motors Research Laboratories (retired); Lewis Branscomb (NAS, NAB), Harvard University (emeritus); David Cole, Environmental Research Institute of Michigan; . . via Kennerly H. Digges, George Washington University; Theodore H. Geballe (NAS), Stanford University (emeritus); Paul J. Joskow, Massachusetts Institute of Technology; James A. Levinsohn, University of Michigan, Ann Arbor; James J. MacKenzie, World Resources Institute; and Marc Ross, University of Michigan, Ann Arbor. Although the reviewers listed above have provided many constructive comments and suggestions, they were not asked to endorse the conclusions or recommendations, nor did they see the final draft of the report before its release. The review of this report was overseen by John Heywood (NAB), Mas- sachusetts Institute of Technology, and Gerald P. Dinneen (NAB), Honeywell Inc. (retired). Appointed by the National Research Council, they were responsible for making certain that an independent examination of the report was carried out in accordance with institutional procedures and that all review comments were carefully considered. Responsibility for the final content of this report rests entirely with the authoring committee and the institution. In addition, the committee reexamined its technical and economic analysis after the release of the Republication copy in July 2001. The results of that reexamination were released in a letter report, which is also included in this report as Appendix F. The reviewers of that report are credited in Appendix F.
