The Ferrari 275 S was a

naturally aspirated form.[4]

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.[4] None of them survive in their original form.[5]

Specifications

The new 'long-block' engine displaced 3,322.34 cc (3.3 L; 202.7 cu in), thanks to 72 by 68 mm (2.8 by 2.7 in) of bore and stroke and had

Weber 40DCF carburettors and used wet sump lubrication. Top speed was 240 km/h.[1]

The chassis was a ladder frame aided by steel tubes of a short, 2,250 mm (88.6 in), wheelbase, derived from 166 MM.[6] This value will change when upgraded to 340 America specification. Front suspension was independent and rear had a live axle with semi-elliptic springs. Stopping was by four-wheel drum brakes.[7]

Between 1950 and 1951 both cars were upgraded with the new 4.1 L, also

Scaglietti, after 1952. The other car remained in the original Touring barchetta form.[10] S/n 0030MT was auctioned in 2015 by RM Sotheby's in Monterey for almost US$8 million.[11]
