The Ferrari 315 S is a sports racing car produced by Ferrari in 1957. The model served as the replacement of the Ferrari 290 MM, which had won the 1956 Mille Miglia and was an effort to dethrone the ever powerful Maserati 450S.[2]
Development
The 315 S employed a front mounted evolution of the 60° Jano V12 engine with two valves per cylinder, six Weber 42 DCN carburettors and four chain-driven overhead camshafts,[3] for a total displacement of 3783.40 cc. Maximum power output was rated to 360 PS at 7,800 rpm in addition to an increase in power output, the engine was also 9 kg lighter than its previous iteration. This allowed for an estimated top speed of 290 km/h.[4][5]
