Trends in Energy Use and Fuel Efficiency of Light Trucks, 1973-1980

摘要

The purpose of this memorandum is to estimate the potential fuel savings of policy initiatives to increase the use of fuel efficient tires and oils in the existing fleet of light-duty vehicles. These estimates are derived with the aid of a Highway Fuel Consumption (HFC) model. Unpublished data from the DOE Office of Policy and Evaluation are used to develop fuel economy improvement factors and penetration rates for fuel efficient tires and oils. Using these data several cases are developed to represent a range of potential fuel savings estimates over the period 1980 to 1985 for oils and 1980 to 1990 for tires. In all instances, it is assumed that the penetration of fuel efficient tires and oils in the in-use fleet remains constant (at 1985 levels in the post-1985 time period for oils and at 1990 levels in the post-1990 period for tires.) The fleet fuel consumption impacts of fuel efficient oils are presented. Potential fuel savings from the increased penetration of fuel efficient tires are outlined. (ERA citation 09:037858)
