This report by the National Research Council's (NRC's) Committee on Review of the FreedomCAR and Fuel Research Program, Phase 3, is the third NRC review. The Phase 1 and Phase 2 reviews were issued in 2005 and 2008, respectively (NRC, 2005, 2008). The long-range goals of the Partnership focus on a transition to a highway transportation system that uses sustainable energy resources and reduces emissions, including net carbon emissions, on a life-cycle or well (source)-to-wheels basis (DOE, 2004). The Partnership focuses on precompetitive research and development (R&D) that can help to accelerate the emergence of technologies that can meet the long-range goals. • This review document is published by National Academies Press.
