Ferrari 315 S

The Ferrari 315 S was a sports racing car produced by Ferrari in 1957. The model was intended to succeed the Ferrari 290 MM, which had won the 1956 Mille Miglia.

Development
The 315 S mounted a frontal V12 engine at 60°, with two valves per cylinder and four chain-driven overhead camshafts, for a total displacement of 3783.40 cc. Maximum power was 360 PS at 7800 rpm, for a maximum speed of 290 km/h.

The Ferrari 315 S drivers took the first two positions in the 1957 Mille Miglia, Piero Taruffi being the winner in his last race, followed by Wolfgang von Trips. In addition the 315 S finished sixth and seventh at Sebring, third at the Nürburgring and fifth at Le Mans but was then largely replaced by the 335 S. The victory of a Ferrari 335 S in Venezuela and the retirement of the Maseratis granted Ferrari the World Sports Car Championship in 1957.

The change in regulations for the World Sports Car championship to a 3-litre engine limit for 1958 meant the 315 S was replaced by the 250 Testa Rossa.
