The influence of alternative automobile and truck emission standards on current and manufacturer developed technologies is examined. A baseline of technology and fuel economy between 1980 and 1990 was established assuming the continuation of currently mandated emissions regulations. Two environmental scenarios were developed from a survey of existing proposals to study the effect of potential changes to the Clean Air Act; one reflected moderate changes and the other maximum changes to the emission standards as compared to the continuation of currently mandated standards. Under each environmental scenario, the fuel economy gains of current and future technologies--primarily engine technologies--are determined from available data and by engineering analysis of the tradeoffs between fuel economy and emissions for each technology. The individual technology impacts were aggregated to provide an estimate of the change in fleet fuel economy from the baseline as a result of changes to the emission standards.
