Ferrari 159 S - 1947


159 S

Developed from the 125 S whose engine was increased to 1903 cc by boring it out and working on the stroke. This model too was fitted out with a monocoque body or with separate mudflap as more attention was now being paid to improving the aerodynamic penetration coefficient. It was used in only three competitions but brought the newly founded Ferrari its first international victory, the Turin Grand Prix won by Raymond Sommer in 1947.
