“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. lt 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.” Source: Concept Car Central
