The GM Project Saturn was a concept car built in 1984. GM called its Project Saturn prototype for the late 1980s "The American answer to the Japanese challenge".

It represented GM‘s largest single commitment aimed at fully-integrating design, engineering and manufacturing and incorporating new technology and assembly techniques. It was planned to enter production as a FWD Chevrolet subcompact smaller than the Cavalier and about 600 pounds lighter.

Plans for the car to enter production included selling the vehicle as a 2-door coupe, 4-door sedan, and a sport utility vehicle.

The fuel- injected 4-cylinder transverse engine was intended to be coupled to a 5-speed manual or 4-speed automatic transmission.
