In the spring of 1957, Ferrari made a further effort on the 12-cylinder engine intended for sports cars, bringing the total displacement to 4023cc. The car that adopted this engine was called 335S, alongside the 315S and 290MM. The 335S showed its full potential at the 1957 Mille Miglia, even if the victory went to Piero Taruffi's 315S. The 335S, however, secured Ferrari the Sport World Championship that year, with a double win at the Venezuelan GP in Caracas. The career of the 335S continued also in 1958, when the official cars received a modified bodywork that was inspired by the lines of the new 250 TR.
