The main inspiration for the car was the high number of deaths in Formula One races, due to the low safety standards.
Among the safety feature were a driver survival cell, multi-layer fuel tanks, a fire extinguisher system, plastic fuel-tanks, a safety-belt-system, an engine with collapsible structures and sidepods protruding behind the rear wheels to prevent interlocking wheels.
The car, designed by Paolo Martin, was based on the Ferrari 312. It had a weight of 590 kg and was powered by a 436 hp 3 liter V12 engine.
The prototype was developed by Pininfarina in partnership with Revue Automobile and with the support of Enzo Ferrari, Fiat and Mercedes.
