n 1970, Lamborghini development driver Bob Wallace created a test mule that would conform to the FIA’s Appendix J racing regulations. The car was appropriately named the Miura Jota. Wallace made extensive modifications to the standard Miura chassis and engine. Weight reductions included replacing steel chassis components and body panels with the lightweight aluminium alloy Avional and replacing side windows with plastic, with the resulting car weighing approximately 800 lb (360 kg) less than a production Miura.

The Alfa Romeo Carabo was built on the Alfa Romeo 33 chassis with a centrally-mounted engine, it became a style classic, known for its creativity and original features, some of which contribute to its legendary standing.

The Lancia Stratos Zero (or 0) preceded the Lancia Stratos HF prototype by 12 months and was first shown to the public at the Turin Motor Show in 1970. The futuristic bodywork was designed by Marcello Gandini, head designer at Bertone, and featured a 1.6 L Lancia Fulvia V4 engine.
