In the mid-1980s, to respond to the offensive of Japanese manufacturers on the American market, General Motors strategists decided to create the Saturn Corporation. Saturn operated almost independently of parent company GM and marketed itself as a 'different kind of car company' The first models were the Saturn SC and Saturn SL whose production began in 1990 as the 1991 model year.

Sales reached their highest level in 1994, with 286,003 vehicles registered. In 2004, GM and the United Auto Workers union had meanwhile dissolved the single labor contract for the Spring Hill plant.
