At the end of 1997, PNGV made its technology selections.
The year 2000 concept vehicle goal was met when the three manufacturers each introduced concept cars -the Daimler/Chrysler ESX3, the Ford Prodigy, and the General Motors Precept.
Each company adopted a different approach to their vehicles, although there were some significant PNGV-related commonalities.
All three concept vehicles utilized hybrid-electric power trains designed around small, turbo charged, compression-ignition direct-injection (CIDI) engines, using diesel fuel.
