Concept Car of the Week: Dodge M4S PPG Turbo Interceptor (1985)

In 1984 Chrysler began the development of a mid-engined, rear-wheel drive car using an experimental powertrain. To avoid the costs of creating a whole new chassis, the M4S is based on a modified Huffaker tubular chassis with full roll cage taken from the Pontiac Fiero IMSA race car, only lengthened to a 100-inch wheelbase.
