GM W Platform - 2004

2004

The W platform was updated in 2004 rather than being replaced by a stretched Epsilon platform, as had been planned. Metal fabrication of the floor pan for W-body cars is performed at the Parma Metal Center in Parma, Ohio. The cars are built at GM's Oshawa Car Assembly. The transverse use of GM's small-block engine in the W-bodies was a major addition for 2005.

The GM W-body platform is in the process of being phased out. The only car remaining on the platform is the Chevrolet Impala. After the 2013 model year, the W-body will have been completely phased out in favor of the GM Epsilon platform.
