Debut 1969 12 Hours of Sebring

The Ferrari 312 P was a Group 6 Prototype-Sports Car used for racing in 1969 and 1970. The new 1971 version of the sports prototype came with a flat-12 engine, often referred to as a boxer engine. Many publications added the letter B after the P of its name to indicate its engine type, but this variation was never officially sanctioned by Ferrari which simply called it the 1971 312P.

After boycotting sports car racing in 1968 to protest a rule change that also banned their 4-litre 330 P4, Ferrari built a 3000cc prototype in 1969, the 312 P. It was hardly more than a 3-litre F1 Ferrari 312 with open Barchetta, and later the closed top Berlinetta.

The first registered race was at the 12 Hours of Sebring in 1969. Ferrari (short on money) started only one 312 P (chassis no. 0868). Mario Andretti got pole position, and with Chris Amon, he managed to finish second. This raised hopes for a prospective Ferrari victory. At the ensuing test weekend at Le Mans, a different car, chassis no. 0870, disappointed, and it was clear that better aerodynamics (with a closed coupe) were necessary. The 0870 also raced at the BOAC 500 in Brands Hatch, where Amon and Pedro Rodríguez finished fourth (behind three Porsche 908-01). At 1000km Monza, Chris Amon took the pole with the 312 P spider, ahead of Jo Siffert's 908-01, but had to retire. The 312 P was not entered in the second Italian race, the Targa Florio, and had to retire in the German 1000 km Nürburgring. At the 1000 km Spa race, a 312 P was second behind the Siffert/Redman 908-01LH. Two 312 Ps were entered in the 1969 24 Hours of Le Mans, now as low-drag Berlinettas. They were fifth and sixth on the grid, but didn't finish.
