Maserati made four naturally-aspirated, V12 racing engines, designed for Formula One, between 1951 and 1969. The first was an experimental O.S.C.A. engine, in accordance with the 4.5 L engine regulations imposed by the FIA for 1951.[1] Their second engine was 250 F1 V12, in accordance with the 2.5 L engine regulations set by the FIA. Their last two V12 engines were customer engines supplied to Cooper, between 1966 and 1969.[2][3][4] The Tipo 9 / F1 and Tipo 10 /F1, which were both manufactured to the FIA's 3.0 L engine regulations for 1966.[5][6][7] One sports car, a modified version of the Maserati 350S, also used V12 engine, with a 3.5 L (210 cu in) displacement, and produced 335 hp (250 kW).[8][9]
