The history and prognosis of personal automotive transportation in the US has been examined to indicate the dramatic improvements in energy efficiency over the 1975-1985 time period. Design factors -- vehicle energy requirements, energy conversion within the power plant and energy transmission within the drive train -- are reviewed. The relative importance of the major design facets, and some of the constraints to their efficiency improvement, both internal and external to the vehicle, are discussed. The author concludes that if current legal efficiency improvement requirements are actually met, and normal trends in car sales continue, a reduction in total U. S. gasoline consumption will occur for the first time in history.
