The car competed in six World Championship Grands Prix over the two seasons, making ten individual entries. Its only points finishing position was a win for Mike Hawthorn at the 1954 Spanish Grand Prix.
The engine was a Lamprediinline-four, producing 260 PS (191 kW; 256 hp) at 7200 rpm, from 2497.56 cc of total capacity. Because of the distinctive rounded bodywork and air-intake it was nicknamed Squalo, meaning Shark in Italian.[3]
555 F1
In 1955, Ferrari updated their existing 553 F1 car. New helical springs were used for the front suspension, instead of the transverse leaf-springs. The rear saw the replacement of a lower leaf-spring to an upper one. It also received a five-speed gearbox instead of a four-speed. It used the same capacity as before and the power output also remained the same.
Because of the extended, rounded bodywork it was further nicknamed as a Supersqualo (Super shark). The car was first used at the Bordeaux GP on 24 April 1955. In 1956, Peter Collins was still using the 555 F1, whilst the rest of the Scuderia drove the Lancia-Ferrari D50.[4]
