General Motors C platform (1925)

  (Redirected from GM C platform (RWD))

The GM C Platform was a rear wheel drive (RWD) automobile chassis used by General Motors for its full-sized cars from 1925 through 1984. From at least 1941, when the B-body followed suit in adopting the C-body's pioneering lower and wider bodystyle with no running boards, it may be viewed as a larger and more upscale version of the GM B platform. It was also related to the limousine D platform. With the introduction of a severely downsized front-wheel drive new GM C platform in 1985 it was redesignated as GM's D platform and continued in production for a number of Cadillac models through 1996.
