GM G Platform (RWD)

GM G Platform (RWD)

The General Motors G platform (also called G-body) was an automobile platform designation used for mid-sized rear wheel drive cars first from 1969-1972 and again from 1982 to 1988. The G-body models began production designated as A-body cars in 1978, but were redesignated as G when the new front wheel drive A-body was introduced in 1982

The G-body designation was originally used for 1969–1972 Pontiac Grand Prix and 1970–1972 Chevrolet Monte Carlo personal luxury coupes.

Between 1973 and 1981 the A-body coupes with formal rooflines were designated as A-Special and after 1982 dubbed as the G-Special. These special coupes included Monte Carlo, Grand Prix, Oldsmobile Cutlass Supreme and Buick Regal two door models.

In 1982, the Chevy Malibu/Pontiac LeMans coupes were dropped along with the Buick/Olds fastbacks. 1983 was the last year for wagons and Chevy Malibu sedans, leaving the G-Special coupes, B-O-P formal-roof sedans and the Chevy El Camino/GMC Caballero. In 1988, most remaining G-body models were moved to the new front wheel drive GM W platform, although the Pontiac Bonneville moved to the H-body, the El Camino was dropped without replacement and there would be a one-year gap before the W-body Chevy Lumina coupe truly replaced the Monte Carlo. GM later used the GM G platform (FWD) designation for unrelated full-sized cars.

G-bodies were some of the last cars to follow the classic muscle car formula, remaining popular while most mid-sized cars moved to front wheel drive. They were also raced in NASCAR.
