Chrysler M platform


The M-Bodies were Chrysler Corporation's successor to the F-body Aspen/Volare. The platform, almost identical to the F-body, was introduced in 1977, and it was the basis for some mid-sized Chrysler models until its demise in 1989. 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.
The M-cars were built at St. Louis, Missouri and Newark, Delaware with initial debut in spring 1977 as late 1977 models, with some 1977-83 production also at Windsor, Ontario. Beginning in late 1986 and through the last 1989 year, the American Motors plant in Kenosha, Wisconsin was also used for production.
By 1983-84, it became clear that most private buyers preferred the equally roomy but cheaper and more fuel-efficient K-cars; however, the M's long-proven traditional engineering, handling, and V8 engine availability appealed to police and taxi fleets, allowing the car's continued existence until the end of the decade.
In 1989 the Chrysler M-bodies received a standard drivers side air bag.
After the M-bodies were discontinued in 1989 Chrysler Corporation wouldn't build a rear wheel drive car outside of trucks and specialty models until LX based cars.
