Ford Panther Platform

The Ford Panther platform is an automobile platform that was used by Ford Motor Company for full-size, rear-wheel drive sedans. Introduced in late 1978 for the 1979 model year, it was progressively updated over 33 years of production. In September 2011, the last car produced on the platform was produced, marking the end of the rear-wheel drive full-size Ford. This also marks the end of the traditional body-on-frame rear wheel drive automobile in the United States since GM's discontinuation of its B platform in late 1996. The only other rear-wheel drive sedan with an available V8 engine currently produced by Ford is the Ford Falcon in Australia.

As of the 2011 model year, the Panther platform was in use longer (32 model years) than any other platform in North American automotive history. It was initially developed as a response to the downsizing of full-size cars from Chrysler and General Motors due to increasingly stringent fuel economy standards for cars. During trying periods for Ford, the Panther cars were scheduled for cancellation and replacement (in favor of the front-wheel drive D186 platform) on several occasions, as early as 1985.

As the 1980s progressed, the full-size cars of the Buick, Oldsmobile, and Pontiac divisions were downsized further; all were replaced by front-wheel drive, mid-size cars. The Panther's final GM counterparts, the Chevrolet Caprice, Buick Roadmaster and Cadillac Fleetwood were discontinued in 1996. During the early 1980s, Chrysler left the full-size car class completely. In the early 1990s, Chrysler resumed production of full-size cars (the LH platform) and rear-wheel drive (the LX platform) a decade later. However, with the majority of these cars, Chrysler competes against different customers that Ford attracts with the Panther platform.

The Panther platform was produced at Ford's St. Thomas Assembly plant in Talbotville, Ontario, Canada, with the last vehicle rolling off the line 15 September 2011. Prior to its closure on 31 May 2007, the Wixom Assembly Plant in Michigan was the assembly site for the Lincoln Town Car. Assembly of the Town Car was consolidated at the St. Thomas plant in January 2008 following paint shop and other upgrades. Ford and Mercury versions built before the 1986 model year were assembled in the St. Louis Assembly Plant in Missouri; this facility is currently closed.
