Evolution of the 250 GTO ( 1961-1964 )

The basis for the 250 GTO was the model 250 GT SWB, SWB stand for "short wheelbase " ( short wheelbase ). The letters GTO stood for " Gran Turismo Omologato ", ie a homologated for racing series. The 250 GTO was developed for use in the Gran Turismo category. The 250 in the model designation stands for the cylinder capacity in milliliters per cylinder.

The body modifications with respect to the underlying 250 SWB was developed by Bizzarrini in the wind tunnel. The most striking change was the completely redesigned front. The rear fenders were wider and longer, as is the rear overhang. Unlike the first prototype of all later copies were given a riveted trailing edge in the form of a spoiler, which in those days was an aerodynamic novelty.

Although the rear rigid axle of the 250 GT SWB had to be retained, but has been optimized with parallel trailing arms and a Watt's link for stabilization. As the Colombo V12 engine was used with 3 -liter displacement and dry sump lubrication, thus the hood could be kept very flat. Due to its 300 hp and good aerodynamics reached the GTO on long straights up to 280 km / h and he was very successful in racing and won in 1962 and 1963, the GT World Championship.

The results of the GTO were impressive, there were victories at the 12 Hours of Sebring, the Targa Florio, the 1000 km of Spa- Francorchamps and Le Mans, where 1962 and 1963 also was second and won the GT championship.
