The Ferrari 335 S was a sport racing car produced by Italian manufacturer Ferrari in 1957-1958. Four cars were produced in total. An evolution of the 315 S, it had V12 engine with a greater 4023 cm³ displacement and a maximum power of 390 HP at 7400 rpm; the maximum speed was around 300 km/h.
This model was the protagonist of the accident in the 1957 Mille Miglia, which led to the cancellation of the race starting from the following year. The 335 S #531, led by Spanish driver Alfonso de Portago (who had replaced an ill Luigi Musso) was in third position, running on a long straight road sector between the Lombard hamlets of Cerlongo and Guidizzolo. When one of the tyres exploded, de Portago's car slipped to the right and crashed against a large crowd, killing nine people, as well as de Portago himself and American co-driver Edmund Nelson. The car later won the Venezuelan Grand Prix, raced by Peter Collins and Phil Hill, and participated to the 1957 24 Hours of Le Mans.
