Any car that comes with a challenge has to be something special, the challenge was for any other production to beat it round a track and $25,000 would be yours, when the more powerful version was built this increased to £100,000. From what I gather the prize was never collected. The premise behind this track/road car was simple, take an average engine (Chrysler’s turbo’d 2.2 litre four-cylinder) found in many American minivans etc and bolt it into the middle of a light body and chassis.
