DOMESTIC PASSENGER AUTOMOBILE WEIGHT PROJECTIONS, 1979-1986 GM, FORD, CHRYSLER, AMC

A preliminary analysis for projecting curb weights of domestic passenger automobiles for the 1979 to 1986 model year period is presented. Using publically available data through July 1978, an estimate of potential weight reduction which each manufacturer might incorporate towards reaching the 1985 fuel economy goals was made based on known product plans and available technology. Four weight categories (sedan and station wagon, with and without options) were calculated by make and model line for each model year, based on individual manufacturer's strategies of weight loss due to (1) all new vehicle design, (2) major sheet metal change, and (3) component redesign and material substitution. Results are presented at the detail level by manufacturer and model and at the summary level by EPA market class. Weight losses from seven to thirty-two percent (depending upon vehicle size) were estimated.
