The Ferrari 275 S was a sports racing car produced by Ferrari in 1950. It was the first Ferrari powered by a new Aurelio Lampredi-designed V12 engine, created as a large displacement alternative to the initial 1,5 L Colombo V12, used in supercharged form in Ferrari 125 F1.[3] Formula One regulations allowed for up to 4.5 L in naturally aspirated form.
Development
The naturally-aspirated, then supercharged Colombo engine did not fulfil its expectations in Grands Prix and Formula One, and an alternative was required for Ferrari to stay competitive. Aurelio Lampredi designed the new V12 engine that was intended for Formula One race cars, but first had to be tested in a sports racing car. Only two examples were ever created. Both had Touring barchetta bodywork. None of them survive in their original form.[4]
