Caterham Seven Supersport R (2012) first pictures

It's certainly been a busy week for Caterham. Just a few days ago the company announced its partnership with Renault to create a new range of Alpine sports cars, and now the Surrey-based outfit has gone back its roots to develop an even more hardcore version of the Seven Supersport. Called the Caterham Seven Supersport R, the lightweight special gets an engine capacity increase and power bump over the regular car, but carries over its racing car-derived suspension.

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

As a major paint supplier of Detroit's big three, PPG would commission every year a car to be used as a pace car in the Indy Car World Series. 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.
