The General Motors X platform (also called X-body) is an automobile platform designation that was used for compact cars with rear-wheel drive. Developed by Chevrolet, the architecture was produced from the 1962 to 1979 model years. During the 1970s, the platform was used by multiple GM divisions as the company expanded its use of compact model lines. For 1980, the platform was discontinued and the X-body designation was reused for its downsized successor, the first front-wheel drive compact car architecture produced by General Motors.
