The B platform, or B-body, was General Motors' full-size rear wheel drive automobile platform. It was closely related to the Cadillac D-body and was used for coupes, sedans, and station wagons. All D- and B-bodies were built in Arlington, Texas.
B-body production began in 1962. The platform was downsized in length by approximately 10 inches in 1977. The last B-cars rolled off the line in 1996, leaving only arch-rival Ford producing large rear wheel drive sedans. Today, however, the situation looks to reverse, with Ford switching to front wheel drive for most cars and GM reintroducing rear wheel drive with their new Sigma platform. Chrysler has also reintroduced rear wheel drive with their new LX platform.
Most B-body cars were replaced by H-bodies.
Sedans built on the B platform include:
