Automobile fuel economy

Abstract

Ten million barrels of oil per day are currently consumed by the world's 300 million passenger cars. The future stock of automobiles can be much more fuel efficient, if technological improvements in the engine-drive train combination are implemented. A quantitative model combining an engine map and a driving cycle is described, and fuel economy savings resulting from specific improvements are estimated; in combination, they lead to cars that achieve 2.6 1100km (90mpg). An important economic barrier to the production of such cars is the relative insensitivity of total lifecycle costs to these improvements; accordingly, governmental fuel economy standards—or incentives such as high taxes on fuel inefficient automobiles—will be required if the technologically and economically achievable automotive fuel economy potential is to be realized.
