Editing General Motors Epsilon platform (section)

==Features==

GM's '''Epsilon''' platform replaced the [[GM N platform|N platform]] in the [[United States|US]], and replaced the [[GM2900 platform]] elsewhere. Vehicles of this platform generally carry the symbol "Z" in the fourth digit of their [[Vehicle Identification Number|VINs]].

When the platform debuted, there was talk of an "Epsilon Wide" derivative, which was supposed to have provided the underpinnings for the [[Buick LaCrosse]] and [[Saab 9-5]]. However, the program was cancelled and the LaCrosse was put on the [[GM W platform|W platform]], and the 9-5 was given a quick refresh for the 2006 model year. {{Citation needed|date=April 2016}}
 
The Epsilon platform is a midsize front-driver promising a 200 percent improvement in rigidity, with aluminum suspension components—MacPherson struts in front and a four-link independent arrangement in the rear, and four-wheel disc brakes. Many of the Epsilon vehicles use the [[GM Ecotec engine|Ecotec]] [[Inline-four engine]]s and both the [[GM High Value engine|High Value]] and [[GM High Feature engine|High Feature]] V6 engines.

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.

The [[GM Lambda platform|Lambda]] and [[GM Theta platform#Theta Premium|Theta Premium]] [[Crossover (automobile)|crossover]] platforms are derived from Epsilon. {{Citation needed|date=April 2016}}
