Ferrari 250P - Ferrari 250P
Background and technology
The 250P was a big break in Ferrari typology. It was the first mid-engined 12-cylinder racing car in the history of the Italian brand. Actually, the FIA wanted to shift the focus of the car classes in the direction of Gran Turismo in the regulations of the sports car world championship for 1963 . The ACO , the organizer of the Le Mans 24-hour race, however, these regulations were too unspectacular because there was fear of massive decline in the number of spectators due to the loss of the large sports cars. The ACO managed to get other sports car racing organizers on their side; together these new regulations were then brought down. After sports cars could also be launched in 1963, Scuderia developed the 250P.
Preparatory work began at the end of 1962. A Ferrari Dino 246SP - chassis 0796 - was converted to use the new 3 liter V12 engine from the Testa Rossato be able to record. To do this, the tubular frame had to be extended. The findings from the test drives were incorporated into the construction of the 250P. The cars had four independent wheel suspensions and disc brakes at the front and rear, with the rear ones being located directly on the differential housing. The unsynchronized gearbox was behind the differential. This made it easy to change the transmission shafts, which meant that the top speed of the racing car could easily be adapted to the conditions of the respective race track by choosing the right gear ratio. The four bodies came from Pininfarina . The car was presented on March 4, 1963 - together with the Ferrari 330LMB - in the pit facilities of the Monza race track .
His racing debut of 250p at 12-hour race of Sebring same with a double victory. John Surtees and Ludovico Scarfiotti won after 208 laps with one lap ahead of teammates Willy Mairesse and Nino Vaccarella . There was also an overall victory in the second outing, the 1000 km race at the Nürburgring . This time Willy Mairesse and John Surtees were partners who remained victorious in front of the surprisingly strong GTO team Pierre Noblet / Jean Guichet .
The next success followed at Le Mans . Ferrari lost one of the three factory 250Ps in an accident by Willy Mairesse, but victory went to a 250P driven by Scarfiotti and Lorenzo Bandini . There was once a total failure at four starts: At the Targa Florio , both of the registered works cars did not finish.
In 1964 the 250P was followed by the 275P .
