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. Ralph J. Cicerone 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 engineers. Dr. Charles M. Vest 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 examina -
tion 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. Harvey V. Fineberg 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 pur-
poses of furthering knowledge and advising the federal government. Functioning in accor-
dance with general policies determined by the Academy, the Council has become the princi-
pal 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
engineering communities. The Council is administered jointly by both Academies and the
Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Charles M. Vest are chair and vice chair,
respectively, of the National Research Council.

Preface
The FreedomCAR and Fuel Partnership has undergone several changes
since its formation in January 2002. Initially, the Partnership was between the
U.S. government (primarily the U.S. Department of Energy [DOE]) and the U.S.
Council for Automotive Research (USCAR), whose members are Chrysler LLC,
the Ford Motor Company, and General Motors Company. Soon after its inception,
in September 2003 five energy companies were added as members: BP America,
Chevron Corporation, ConocoPhillips, ExxonMobil Corporation, and Shell Hydro-
gen (U.S.). More recently, in 2008, two major power companies, DTE Energy
(Detroit) and Southern California Edison, were added as members.
The Partnership developed a roadmap including many individual milestones
and technical targets to pursue the original goal of “a full spectrum of vehicles
that can operate free of petroleum and harmful emissions while sustaining the
driving public’s freedom of mobility and freedom of vehicle choice.”1 The long-
term emphasis was on hydrogen fuel cell vehicles with hydrogen as the primary
transportation fuel, but the Partnership envisioned utilizing transition technologies
of advanced internal combustion engine vehicles and advanced hybrid electric
vehicles en route to hydrogen/fuel cell vehicles.
With the change from the Bush to the Obama administration, there was an
increase in emphasis on nearer-term technologies, especially those involving more
electrification of the vehicles, such as plug-in hybrid electric vehicles. However,
the charge to the Committee on Review of the FreedomCAR and Fuel Research
Program, as well as presentations to the committee, involved performing an
evaluation of activities between Phases 2 and 3, which included few activities

involving all-electric (battery electric vehicle or plug-in hybrid electric vehicle)
technologies, or biofuels.
This report is the final full report, following a shorter letter report issued
in July 2009,2 for Phase 3 of the study of the Committee on Review of the
FreedomCAR and Fuel Research Program as chartered by the National Research
Council in the fall of 2008. It provides an overview of the structure and manage -
ment of the Partnership as well as a discussion of the Partnership’s adequacy,
progress, and technical problem areas. Recommendations are also included in
areas where the committee believes that improvements can be made.

Acknowledgments
The committee wishes to thank the members of the FreedomCAR and Fuel
Partnership, all of whom contributed a significant amount of their time and effort
to this National Research Council (NRC) study by giving presentations at meet -
ings, responding to requests for information, or providing valuable information.
The chair also recognizes the committee members and the staff of the Board on
Energy and Environmental Systems for their hard work in organizing and plan -
ning committee meetings and their individual efforts in gathering information and
writing sections of the report.
This report has been reviewed in draft form by individuals chosen for their
diverse perspectives and technical expertise, in accordance with procedures
approved by the NRC’s Report Review Committee. The purpose of this inde-
pendent review is to provide candid and critical comments that will assist the
institution in making its published report as sound as possible and to ensure that
the report meets institutional standards for objectivity, evidence, and responsive -
ness to the study charge. The review comments and draft manuscript remain
confidential to protect the integrity of the deliberative process. We wish to thank
the following individuals for their review of this report:

Although the reviewers listed above have provided many constructive com-
ments and suggestions, they were not asked to endorse the conclusions or rec-
ommendations, nor did they see the final draft of the report before its release.

This report is dedicated to our dear friend and colleague Dr. Craig Marks
(1929-2009), who served on all three National Research Council (NRC)
committee reviews of the FreedomCAR and Fuel Partnership, chairing
the first two. Craig devoted most of his working career to advancing
automotive technologies and generously volunteered his considerable
knowledge and skills to work not only with this committee but also with
all seven phases of its predecessor, the NRC committee that reviewed
the Partnership for a New Generation of Vehicles (PNGV) program.
His many contributions, friendly manner, and thoughtful insights will
be greatly missed.
