Ferrari 250 GTO

Ferrari 250GTO (1962)A development of the 250 SWB, the GT Omologato first appeared in 1962. Developed by Giotto Bizzarrini and a small team of engineers during 1961, they built a single prototype which used parts from a variety of then current production cars, as well as a 500TR engine. Some limitations were imposed by the need to homologate the car as a variant of the SWB. A total of 39 were built, including three which were fitted with the 4-litre engine. In 1963 three 'second series' cars were built with an all new body (plus four first series cars which were converted).

The normal engine was a 2953cc V12 unit with a single cam in each bank, two valves per cylinder, an alloy block and heads and is fed by six Weber 38DCN twin carburettors. It produced 290bhp @ 7,400rpm, although various levels of race trim gave various results. It was positioned lower, thanks to a dry sump, and further back than in the SWB, a fact which enabled the GTO to have a lower and considerably more aerodynamic nose. The suspension, supposedly for homologation reasons, retained the live rear axle of the SWB whilst the front used an independent wishbone setup.

With the GTO Ferrari won the World Championship in 1962, 63 and 64, with most famous races falling prey to the GTO including the Sebring 12 hours in all three years, the Le Mans 24 hours in 62 and 63, the Tour de France in 1964, the Targa Florio in all three years, the Nurburgring 1000km in 63 and 64 and so on.
