The Ferrari P2 is a car that took part in the World Sportscar Championship in 1965 .
Two entirely new cars, the 275 P2 and 330 P2, followed in 1965. Featuring lower and lighter chassis and more aerodynamic body, the cars were paired with revamped versions of the previous 275 and 330 V12, now equipped with four camshafts and producing 350hp and 410hp, respectively. The 330 P2 was first used by Luigi Chinetti's North American Racing Team (NART) in the Daytona race that year. In 1965 275 P2 0836 won the 1000 km of Monza, 275 P2 0828 won the Targa Florio, 330 P2 0828 won the Nurburgring 1000 km, and 365 P2 0836or0838 won the 12 hr. Reims. The P2 cars were replaced by the P3 for 1966.
The project
Ferrari P2, built by Ferrari to compete in the worldwide prototypes of 1965, was produced in two versions, the 275 P2 and P2 330 . These represent the natural evolution of the P 275 and P 330 that had over the season 1964. The engines were the same that equipped the previous versions, but on P2 is passed to the distribution DOHC , which along with new carburetors of Weber increased the power of the two cars, 350 respectively CVfor 275 P2 and 410 hp for the 330 P2. The frame was completely redesigned from the previous version. To the classic trellis d 'tubes steel were riveted of the plates d' aluminum , so as to increase the rigidity of the car without excessive increases in weight. This solution, invented by the British assemblers Formula One , had been used by for the first time since Ferrari on the 158 , the car that the previous year had won the drivers' title with John Surtees . The P2 accounted for Ferrari the first application of this technique in a sports car. The body, in boat , was made of aluminum. Than previous cars were abandoned circles ray, which were replaced by new and lighter made of alloy magnesium . In total 275 they were produced four P2, identified by the chassis number 0826, 0828, 0832 and 0836 . Two, the 0828 and 0832, will be changed to 330 P2. To these we add a third 330 P2, built from scratch, with chassis number 0838 .
The season 1965
The challenge of the Ford
At the beginning of the sixties , the Ferrari was in financial crisis, and Enzo Ferrari decided to sell the majority of his company. Not satisfied with the offer of Fiat , turned American Ford , who have long sought a way to enter the world of competitions. In fact, the true will of Enzo Ferrari was only to get an answer better offer from Fiat itself, as it turned. Ford, realized the deception, he decided to produce their own a race car to challenge Ferrari. In collaboration with Carroll Shelby , in 1964 he created the GT40 , which will become the biggest opponent of Ferrari in the World prototypes for the three years to come.
