GM launched Saturn Corporation in the 1980s to compete with Japanese import cars. The idea behind Saturn was to launch a completely new type of compact car. The Saturn sedan was different than anything else in the GM brand portfolio. The brand was established as its own company with its unique dealership network (via Auto Trends).
The first model was the SL2 and it was a unique design. The problem was that the entire company was brand new from the factory to the workforce, and GM lost money. By the 2000s the Saturn brand was nothing more than a home for badge-engineered GM cars.
