The Chrysler M Platform was an intermediate-sized automobile platform used by Chrysler motors from 1977 to 1989. It was a successor to the F-body, as used on the Dodge Aspen/ Plymouth Volare. The M-body was also the successor to the short-lived R-body, as the Chrysler New Yorker and Plymouth Gran Fury moved to it following the R-body's demise in 1981. The M platform was the final production passenger car with a solid rear axle mounted on Hotchkiss-style, parallel semi-elliptical leaf springs sold in the U.S.
