The 275 GTB was a two-seat grand touring coupé produced between 1964 and 1966. The name of this model was derived from the engine's per-cylinder displacement of 275 cc and the Italian designation Gran Turismo Berlinetta. The 275 GTB used a double overhead cam 3.3 litre Colombo-designed 60º V-12 engine designated Tipo 213. Power was claimed to be 280 horsepower (210 kW) at 7600 rpm, but provided closer to 240-250 hp (190 kW) in actual use. The majority of 275s were equipped with a standard three-carburetor manifold, but a factory option of six twin-choke Weber 40 DCN carburetors was also available, known today as the 275 GTB/6C.
