Epsilon is General Motors' mid-size front-wheel drive automobile platform. The architecture was a multi-division project of GM North America, Opel and Saab, and debuted in the 2002 Opel Vectra and 2003 Saab 9-3. Since this platform falls squarely in the center of the worldwide automobile market, GM plans to produce a great many Epsilon vehicles with over a dozen variations. As of 2005, it was GM's highest volume worldwide platform. Even after the dissolution of the GM/Fiat partnership, both companies retain the rights to continue developing Epsilon-derived models.
A total of 16 different models have made use of the GM Epsilon platform, some of which remain in production 19 years after the platform debuted.
