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 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: 1976-1985 Buick LeSabre 1971-1981 Pontiac Bonneville 1977-1990 Pontiac Parisienne 1971-1975 Pontiac Catalina 1973-1985 Chevrolet Impala 1971-1976 Oldsmobile 88 1977-1985 Oldsmobile 88 1988-1990 Chevrolet Caprice 1991-1993 Chevrolet Caprice 1994-1996 Chevrolet Caprice Classic 1992-1996 Buick Roadmaster 1994-1996 Chevrolet Impala SS Station wagons include: 1988-1990 Chevrolet Caprice 1991-1993 Chevrolet Caprice 1994-1996 Chevrolet Caprice Classic 1977-1990 Oldsmobile Custom Cruiser 1991-1992 Oldsmobile Custom Cruiser 1988-1989 Buick Electra Estate 1986-1990 Buick Estate 1991-1996 Buick Roadmaster
