The 275 GTB was a two-seat Grand Touring automobile produced between 1964 and 1968 with a 3.3 liters (3,286 cc) Colombo 60-degree V-12 engine and produced 280-300 horsepower.
The standard 275 GTB coupe was produced by Scaglietti and was available with 3 or 6 Weber twin-choke carburettors. It was more of a pure sports car than the GT name suggested. Some cars were built with an aluminium body instead of the standard steel body. A Series Two version with a longer nose appeared in 1965.
