G-Body FWD Wiki

The General Motors G platform (also called G-Body) automobile platform designation was used for front-wheel drive full-sized and luxury cars between 1995 and 2011. Previously, General Motors used the G-body designation for unrelated mid-sized cars. The G-body was based on Cadillac's K-body architecture. The platform was introduced in 1995 with Buick Riviera 2-door coupe (which moved up from the GM E platform) and the Oldsmobile Aurora 4-door sedan (a new model that replaced the Riviera-derived Toronado). By the turn of the millennium, full-sized cars from four different GM makes were using some derivative of the platform.
