Ferrari 156

Ferrari 156 sharknose, carro usado por Phill Hill e Wolfgang Von Trips em 1961, usava motor 1.5 litros, 6 cilindros a 120°, potência de 190hp. Com este modelo Hill ganhou o título daquele ano. Com algumas mudanças o carro continou a ser usado até 1964. Kit Revival, escala 1/20.
The 156 was made by Ferrari in 1961 to comply with then-new F1 regulations that lowered engine displacement from 2.5 to 1.5 litres, similar to the pre-1961 F2 class for which Ferrari had developed a mid-engined car also called 156. It used the V6 "Dino" engine named after Enzo Ferrari's late son.
The new engine was a revised F2 engine with the V-angle increased from 65 to 120 degrees, this increased the power by 10 hp. Bore and stoke were 73.0 x 58.8 mm with a displacement of 1,476.60 cc and a claimed 190 hp at 9,500 rpm. For 1962 a 24-valve version was planned with 200 hp 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.
A V-6 engine with 120 degree bank is smoother at producing power due to the fact of every 120 degree rotation of engine crankshaft produces a power pulse.
It is one of the most iconic racecar shapes and one of the most distinctive of all Ferraris. Phil Hill won the 1961 World Championship of Drivers and Ferrari secured the 1961 International Cup for F1 Manufacturers, both victories achieved with the 156.The last victory for the Ferrari 156 was by Italian Lorenzo Bandini in the 1964 Austrian Grand Prix.
The 1961 version was affectionately dubbed "sharknose" due to its characteristic air intake "nostrils". Kit Revival, 1/20th scale.
