GM A platform (1982)


Overview

The General Motors A platform 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. They were initially offered alongside, but eventually supplanted rear-drive nameplates such as the Malibu for the intermediate niche.Due to the strong popularity of the older rear wheel drive design, General Motors continued production as the G-Body until 1988.
Introduced for the 1982 model year, the A-Body cars were essentially similar in mechanical design and interior space to the troubled X-car compacts upon which they were derived. One key difference between the two platforms is that the A-Body cars are long enough to be classified as intermediate cars due to their more traditional styling. Initially all four lines offered two and four door sedans for 1982. In 1984, they added a wagon body style, which replaced the rear wheel drive G-Body wagons, which were discontinued after 1983.

Platform Updates

The A-body eventually consisted of a 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. It also briefly saw duty as an all wheel drive platform for the Pontiac 6000.
Later GM platforms benefited from components and systems developed with the A-Body. Additionally the first generation U-body minivan 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.
