Ferrari 857S

The short-lived 857S of 1955 was an attempt to hold off the strong Mercedes-Benz team, something the 750 Monza and the 376 S/735 LM had been unable to do. An existing 750 Monza chassis received an enlarged version of Lampredi’s four, now displacing 3.4 litres (3,431.93 cc; 209.4 cu in) and producing 280 hp (206 kW). The car was not competitive with the German team at the 1955 Tourist Trophy, so Lampredi went back to the drawing board for the next season. At the 1955 Targa Florio, the 857S came third overall, driven by Castellotti. A year later, at the 1956 1000 km Buenos Aires, Olivier Gendebien and Phil Hill scored second place.
