GM B platform
Encyclopedia : G : GM : GMB : GM B platform
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 coupés, sedans, and station wagons.
B-body production began in 1962, and had 4 major restyles in 1965, 1971, 1977, and 1991. 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.
The B-body was the last platform design to have the gasoline tank filler nozzle behind the license plate.
Most B-body cars were replaced by H-bodies.
