GM G platform (FWD)
Encyclopedia : G : GM : GMG : GM G platform (FWD)
The General Motors G platform (also called G-Body) automobile platform name was used twice. The current G-bodies use this front-wheel drive version, and it replaced the C-body (discontinued in 1996).
The second G-body platform (the GMX690) was used for front-wheel drive luxury cars from 1995. The new G-body was based on Cadillac's K-body architecture. The Buick Riviera moved up from the GM E platform, while the Oldsmobile Aurora was a new model. The Buick Park Avenue migrated to the G-body in 1997 and remained unchanged until its demise for 2005. A short-wheelbase version was introduced in 2000 to replace the H-body, as the Buick LeSabre and Pontiac Bonneville moved to that platform.
With the demise of the Bonneville, Park Avenue, and LeSabre after 2005, the only remaining G-body car will be the Buick Lucerne. This vehicle again shares a platform which is similar to the K-body. The K-body cars were replaced by a single ongoing model, the Cadillac DTS.
The G-body featured a four-wheel independent suspension.
