General Motors' new mid-size front-wheel drive automobile platform. The architecture debuted in the 2002Opel 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 is GM's highest volume worldwide platform (or "architecture" in GM-speak). Even after the dissolution of the GM/ Fiatpartnership, both companies retain the rights to continue developing Epsilon-derived models.
When the platform debuted, there was talk of an "Epsilon Wide" derivative, which was supposed to have provided the underpinnings for the
Buick LaCrosseand Saab 9-5. However, the program was cancelled and the LaCrosse was put on the W platform, and the 9-5 was given a quick refresh for the 2006 model year.
Control of the Epsilon platform has passed, as of
2005, to GM Europe. Headquartered with Opelin Rüsselsheim, Germany, GM Europe will be responsible for all future Epsilon product decisions other than Saab and Cadillacmodels.
The refreshed 2008 SAAB 9-3 debuted with an advanced version of all-wheel-drive it dubbed XWD, finally giving a definitive answer to rumors about the platform's ability to support AWD, which had been around since the debut of the platform.
Current vehicles based on this platform:
** 2002 Opel Vectra
Chevrolet Malibu Maxx
Cancelled vehicles which would have used this platform:
Alfa Romeo Spiderreplacement (AWD, eventually used the GM/Fiat Premium platform)
* 2006 small
Jeremy Clarkson, whilst driving a Vauxhall Vectra built with this chassis, described it as "one of the worst chassis I've ever come across", due to the way the Vectra with the 2.8 V6 turbo torque steered and was unable to handle its power. Improvements to the Vectra have been made, and the 9-3 with this engine was much better in regards to power management. [ cite video
