GM G platform (FWD)

The General Motors G platform (also called G-Body) automobile platform designation was used for front-wheel drive full-sized luxury cars between 1995 and 2003. It is related to the C, H, and K platforms.

Previously General Motors used the GM G platform designation for unrelated mid-sized cars.

The G-body (the GMX690) was based on Cadillac's K-body architecture. The Buick Riviera 2-door coupe moved up from the GM E platform, while the Oldsmobile Aurora 4-door sedan was a new model. In 2000, the G-body was used as the basis for the revised GM H platform .

The G-body featured a four-wheel independent suspension and an extremely resilient structure. For its time, the G-body was one of the strongest unibody car frames in production (25Hz). This fact did not go untouted as GM literature made light of the need to use a 'frame crusher' designed to test heavy-duty truck frames to finally break the G-body structure in their crush-to-failure procedures.
