For the cars collectively known as Saturns, see Saturn S-Series.
Saturn is a division of the General Motors Corporation and a brand of automobiles. It was established on January 7, 1985. As a wholly-owned subsidiary of GM, it manufactures automobiles in the United States. GM began manufacturing Saturn cars in 1990, largely in response to the success of Japanese & German small-car imports in the United States, such as Nissan, Toyota, and Volkswagen. Starting in the 21st century, Saturn is becoming the US brand for Opel vehicles, similar to Vauxhall Motors in the UK.
