The General Motors A platform (commonly called A-body) was a rear wheel drive automobile platform designation used from at least 1936 until 1958, and again from 1964 to 1981. In 1982, GM introduced a new front wheel drive A platform, and existing intermediate rear wheel drive products were redesignated as G-bodies.
The earliest GM A-bodied based cars shared a common platform with the Chevrolet Superior, with Pontiac replacing Oakland during the early 1930s. Oldsmobile also used the A-body for the 1936-39 Oldsmobile Series F and 1940-48 Series 60. All Chevrolets produced during this period, to include the Chevrolet Master and the Chevrolet Deluxe, and all 1936-39 Pontiacs, the 1940 Pontiac Deluxe, the 1941 Pontiac Deluxe Torpedo and all Ponticac Torpedoes produced from 1942 through 1948 were A-bodies.
From 1949-1958, only Chevrolets (150, 210, Bel Air, Del Ray, Biscayne, and Impala), Pontiacs (Chieftain, Star Chief, Super Chief, Bonneville,), and Oldsmobile models 76 and 88 in 1949 and 1950 and Oldsmobile 88-A in 1951, were built on the A-body. These cars were moved to the new B Body shared with some Buicks and Oldsmobiles in 1959.
