A -reduction in exterior - dimensions - 152 mm (6 in.) in the wheelbase and 470 mm (18.5 in.) in the overall length - account for a portion of the --~ weight saving in themselves. Resizing also allowed | weight reduction of related components or systems through weight com- pounding. As the weight of the car decreases, Oldsmobile engineers explain, ~ tires, wheels, suspensions, brakes, steering. and structure are all affected to the point that their weights can-be reduced | and still provide the same level of performance, func- tion and durability. In the case of the 1980 Oldsmobile Omega --weight © compounding allows _ re- designing of the following systems: a aeoad x -Frame and front end sheet metal saves 49 kg (110 Ibs.).
