The General Motors A platform (commonly called the A-body) was a mid-size car automobile platform designation used from 1982 to 1996. Previously the A body designation had been used for rear wheel drive mid-sized cars. The Chevrolet Celebrity and platform-mates were introduced in the 1982 model year which were essentially similar in mechanical design and interior space with the troubled X-car compacts, but long enough to be classified as intermediate cars with more traditional styling. They were initially offered alongside, but eventually supplanted rear-drive nameplates such as the Malibu for the intermediate niche.
The A-body consisted of 4-door sedan, 2-door coupé and a 4-door station wagon It was updated in 1989 with a slightly longer wheelbase and a more rounded roofline (except for the Celebrity whose roofline remained unchanged as it was to be phased out in 1990). It also briefly saw duty as an All Wheel Drive platform for the Pontiac 6000.
Later GM platforms (specifically transaxle based, i.e. four-wheel drive and mid-engine rear-wheel drive) benefited from components and systems developed with the A-Body. Additionally the first generation U-body minivan (1990–1996) was constructed utilizing lightly modified A-body chassis.
The A-body began to be phased out in favor of the GM W platform beginning in 1990, although production did not end for the until 1996 due to popularity of the remaining models.
