A platform (informally called the A-body) was a mid-size platform designation used from 1982-1996. Previously the A body designation had been used for rear wheel drive mid-sized cars. They were initially offered alongside, but eventually supplanted rear-drive nameplates such as the Malibu for the intermediate class.1982 Chevrolet Celebrity

Introduced for the 1982 model year, the A-Body cars were essentially similar in mechanical layout and interior space to the troubled X-car compacts on which they were based, though longer and classified as intermediates. Initially all four lines offered two and four door sedans for 1982. In 1984, they added a wagon, replacing the rear wheel drive G-Body wagons, which were discontinued in 1983.

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 a lightly modified version of the 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 platform until 1996 due to popularity of the remaining models.
