This paper explores the apparent dichotomy between the performance benefits of supercharging and fuel economy. Following an investigation of the tools available for fuel savings, especially drivetrain and engine alternatives, the desirable characteristics and optimum configuration of a supercharger are examined. Engine dynamometer data for a 1.7-liter gasoline engine equipped with a Bendix Supercharger and performance and test data from Bendix-supercharged test vehicles confirm that supercharging provides a means to achieve fuel economy, performance, driveability, and acceptable emissions.
