The Ferrari 156 was a racecar made by Ferrari in 1961 to comply with then-new Formula One regulations that reduced engine displacement from 2.5 to 1.5 litres, similar to the pre-1961 Formula Two class for which Ferrari had developed a mid-engined car also called 156. Ferrari started the season with a 65 degrees Dino engine, then replaced by a new engine with the V-angle increased to 120 degrees and designed by Carlo Chiti. This increased the power by . Bore and stroke were 73.0 x with a displacement of 1,476.60 cc and a claimed at 9,500 rpm. For 1962 a 24-valve version was planned with at 10,000 rpm, but never appeared. In 1963 the 12-valve version fitted with Bosch direct-fuel injection instead of carburetors achieved that power level. The last victory for the Ferrari 156 was achieved by Italian Lorenzo Bandini in the 1964 Austrian Grand Prix. A V-6 engine with 120 degree bank is smoother at producing power because every 120 degree rotation of engine crankshaft produces a power pulse. Phil Hill won the 1961 World Championship of Drivers〔FIA Yearbook 1973, Grey section, pages 118–119〕 and Ferrari secured the 1961 International Cup for F1 Manufacturers,〔FIA Yearbook 1973, Grey section, pages 120–121〕 both victories achieved with the 156.〔Peter Higham, The Guinness Guide to International Motor Racing, 1995, pages 38–40〕 ==Sharknose== The 1961 version was affectionately dubbed "sharknose" due to its characteristic air intake "nostrils". Then-Ferrari factory policy inevitably saw all the remaining sharknose 156s scrapped by the end of the 1963 season. Nevertheless such an F 156 is exhibited in the "Galleria Ferrari"〔(Ferrari World: the official website dedicated to the Galleria Ferrari )〕 at Maranello, probably a replica. A similar intake duct styling was applied over forty years later to the Ferrari 360. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ferrari 156 F1」の詳細全文を読む スポンサード リンク
