The W-platform was a General Motors automobile platform which underpinned both mid size and full-size front-wheel drive cars. Originally code named GM10, it began development in 1982 under Chairman Roger B. Smith and debuted in 1988 with the Pontiac Grand Prix, Buick Regal, and Oldsmobile Cutlass Supreme coupés. The four-door sedan version was introduced for 1990.
