flexible manufacturing and reduction of costs and lead times, while reducing the environmental impact and/or improving quality.

GOAL 2—Implement commercially viable innovations from ongoing research on conventional vehicles.

Pursue technology advances that can lead to improvements in the fuel efficiency and reductions in the emissions of standard vehicle designs, while pursuing advances to maintain safety performance. Research will focus on technologies that reduce the demand for energy from the engine and drivetrain. Throughout the research program, the industry has pledged to apply those commercially viable technologies resulting from this research that would be expected to significantly increase vehicle fuel efficiency and improve emissions.

GOAL 3—Develop vehicles to achieve up to three times the fuel efficiency of comparable 1994 family sedans.

Increase vehicle fuel efficiency to up to three times that of the average 1994 Concorde/Taurus/Lumina automobiles with equivalent cost of ownership adjusted for economics.

According to the schedule for Goal 3 that is described in the program plan, by 1997 the PNGV expects to assess system configurations for alternative vehicles and to narrow its technology choices, with the intent of defining, developing, and constructing concept vehicles by 2000 and with the production of prototypes by 2004. The technology areas being addressed include advanced lightweight materials and structures; energy efficient conversion systems (including advanced internal combustion engines, gas turbines, and fuel cells); hybrid electric propulsion systems; energy-storage devices (including high-power batteries, flywheels, and ultracapacitors); more-efficient electrical systems; and energy recovery systems, such as those for efficiently recovering and utilizing exhaust energy and braking energy.

For Phase 2 of the PNGV peer review, additional members were added to the committee to provide the expertise necessary to assess developments in the program since the first review; notably, in the areas of energy conversion, powertrain technologies, and systems analysis. Biographical information on committee members is presented in appendix A. The committee was charged with performing the following tasks:

  • Assess the progress of the PNGV program since August 1994 and its response to the recommendations from the first NRC review.

  • Examine ongoing research activities in the PNGV, that is, in the various agencies of government (including the
