The Ferrari Sigma, also known as the Ferrari Sigma Grand Prix or Pininfarina Sigma, was a Formula One show car built in 1969 by Pininfarina.

Specification

The Sigma, unveiled on 13 March 1969 in Geneva, was a prototype that was never intended to compete in any Formula One races.^[2] The main inspiration for creating the car was the high number of fatalities among Formula One drivers due to low safety standards.^[3] The Sigma was built in 1969 in cooperation by Pininfarina and Revue Automobile with the support of Enzo Ferrari, Fiat and Mercedes.^[3]^[4] The name of the car ("Sigma") was chosen because several years before Pininfarina had built an experimental safety vehicle with that name, a 1963 Pininfarina PF Sigma.^[3]

The car was designed by Paolo Martin.^[2] It was based on the Ferrari 312 and weighed 590 kilograms (1,300 lb).^[4]^[5] It was equipped with a 3.0 litre V12 engine with 436 horsepower (325 kW).^[1] This car was to be a "future car", showing mainly new safety standards. There were many innovations in it, such as a driver survival cell, multi-layer fuel tanks, a fire extinguisher system, plastic fuel-tanks, a safety-belt-system and sidepods protruding behind the rear wheels to prevent interlocking wheels.^[3]^[5]

The original car is owned by Pininfarina.^[3]
