... Figures 4-1, 4-2, and 4-3 are photographs of the three PNGV concept vehicles. All of the concept cars incorporate hybrid-electric drive trains designed around small turbocharged CIDI engines that shut down when the vehicle comes to rest.

... The Precept fuel-cell vehicle is designed with 105-kW peak, 75-kW continuous power, hydrogen-air PEM fuel cell operating at 1.5 bar, together with two hydride storage tanks expected to hold a total of 4.9 kg of hydrogen, all within the vehicle structure described above. In addition to the fuel-cell stack, the system

... The power train, which is considerably simpler than the power train for the GM Precept, consists of a 1.2-liter, four-cylinder, CIDI, turbocharged 55-kW aluminum engine with a starter/alternator that replaces the engine flywheel. A five-speed, automatically shifted, manual transmission is used.
