ON-ROAD FUEL ECONOMY TRENDS AND IMPACTS
As part of an ongoing analysis of motor vehicle fuel demand, the Department of Energy has undertaken a study of light duty vehicle on-road fuel economy as it compares to the Environmental Protection Agency measured fuel economy test results for similar vehicles. The results of the first phase of this study are used in conjunction with a vehicle fuel consumption accounting model to estimate in-use fuel economy trends and to project demand for gasoline and diesel fuel by light duty vehicles. This report describes the status of the DOE data base which contains information on over 12,000 in-use vehicles of models years 1974-1977 and the most recent results of the second phase analysis. Fuel economy trends for new vehicles and the total on-road fleet are presented based on fuel economy standards requirements and the relationships between EPA and on-road fuel economy. The impact on fuel consumption of EPA/on-road fuel economy discrepancies is analyzed and projections of fuel consumption by both vehicle and fuel type are made for 1978 to 1990, based on on-road fuel economy trends, econometrically based auto sales estimates, information on vehicle miles traveled, and auto scrappage data.
