NEAR TERM WEIGHT REDUCTION POTENTIAL IN A 1977 GENERAL MOTORS B BODY VEHICLE

The report presents an analysis of the potential for weight reduction through lightweight material and component substitutions in a 1977 General Motors Corporation B body vehicle. The changes were limited to those that appeared producible in the 1980 to 1985 time frame. The first portion of the analysis involved gathering weight data on selected components of a 1975 Chevrolet Impala 4-door sedan and a 1977 Chevrolet Impala 4-door sedan. The second portion of the analysis involved the estimation of the potential weight reductions possible in the 1977 Impala through material and component substitutions. The vehicle's components were broken down into three different but interactive categories: the occupant compartment structure, the suspension/steering/braking system and the drive-train. Materials and component substitutions were conservatively carried out so as not to affect the appearance, safety or acceleration performance of the vehicle.
