This never gets old: Ford Supervan
The Ford Transit Supervans were a series of promotional vehicles built for the Ford Motor Company in the UK. They combined the outline and appearance of the popular Ford Transit van with the chassis and performance of a sports racing car.
The Supervan first appeared at the Easter 1971 meeting at Brands Hatch. A GT40 chassis and its mid-engined 400 bhp Ford V8 gave a standard pressed-steel Mark 1 Transit bodyshell a claimed top speed of around 150 mph. The vehicle had been built for Ford by Terry Drury Racing. Externally the van appeared very like a standard Transit, in Ford’s racing livery of white with low horizontal triple blue stripes. The wheel arches were flared to almost cover the wider wheels, but this was barely more noticeable than the extensions fitted to the production long-wheelbase Transit. Aerodynamics of the high-mounted bodyshell were crude though, and although the van was usually demonstrated with drag starts, body lift limited its top speed on a track (source).
