GM Epsilon platform

Epsilon is General Motors' new mid-size front wheel drive automobile platform. The architecture debuted in the 2003 Saab 9-3 and Opel Vectra. 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 2004, it is GM's highest volume worldwide platform (or architecture in GM-speak). Even after the dissolution of the GM/Fiat partnership, both companies retain the rights to continue developing Epsilon-derived models.

GM's Epsilon platform replaces the N platform in the US, beginning in 2006.

Many of the Epsilon vehicles will use the Ecotec I4 and V6 engines.
