Ferruccio Lamborghini never planned on building a race car, but the wild-eyed guys from Chrysler who bought the tractor firm thought it'd be a great idea. The late 80's saw the development of an F1-spec V-12 3.5 liter engine purchased by a few teams gaining some success. In 1991 a Mexican financier wanted not only a Lamborghini engine, but also a car built by the firm to go with it. He disappeared, but the car was built as you see it above. The engine is below with clear Chrylser markings.
