Ferrari 156 F1

The 1961 version was affectionately dubbed "sharknose" due to its characteristic air intake "nostrils". Ferrari factory policy saw all the remaining sharknose 156s scrapped by the end of the 1963 season. Nevertheless, such a 156 is exhibited in the "Galleria Ferrari"[5] at Maranello, probably a replica. A similar intake duct styling was applied to the five SP-series Ferraris[6] in 1961 and 1962 that were also designed by Carlo Chiti, and then again over forty years later to the Ferrari F430.

Ferrari started the season with a 65-degree Dino engine, then replaced by a new engine with the V-angle increased to 120-degrees and designed by Carlo Chiti. 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. This change increased the power by 7 kW (10 hp). Bore and stroke were 73.0 mm × 58.8 mm (2.87 in × 2.31 in) with a displacement of 1,476.60 cc (90.108 cu in) and a claimed 140 kW (188 hp) at 9500 rpm.[7] For 1962, a 4-valve per cylinder version was planned with 147 kW (197 hp) at 10,000 rpm, but never appeared. At the 1962 British Grand Prix, Phil Hill raced a new version with a six-speed transmission mounted in front of the engine. In August, at the German Grand Prix, Lorenzo Bandini tested a non-sharknose variant with modified front and rear suspension and a smaller radiator,[8] heralding the 156 Aero used in 1963.

The updated Ferrari 156, used in the 1963 and 1964 seasons, did not feature the distinctive sharknose design.[9] but had a rather conventional intake, somewhat larger than the Ferrari 158 introduced in 1964.

In 1963 the 120° V6 employed Bosch direct-fuel injection instead of carburetors and output increased to 147 kW (197 hp). The last victory for the Ferrari 156 was achieved by Italian Lorenzo Bandini in the 1964 Austrian Grand Prix.[10]
