Abstract
A series of road, engine, chassis dynamometer, and accessory power consumption tests was conducted in order to characterize the fuel economy of 1973 standard and intermediate size vehicles.
Devices and systems which appeared to offer fuel economy benefits were evaluated by means of an analytical procedure. The study was limited to hardware which could be in production by the 1980 model year. The evaluation procedure was based on urban and steady speed operation, and the effects of compliance with future emission standards were included.
Combinations of individual improvements were selected and applied to the same vehicle. The evaluation procedure was repeated, and fuel economy improvements of 30 to 70% were predicted by comparison with 1973 model year vehicles.
