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.

History

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.

Car in Racing

The first registered race was at the

1000 km Spa race, the 312 P of Rodriguez and David Piper was second behind the Siffert/Redman 908-01LH.[4] 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.

, where one of them was raced (as opposed to eleven 512s). The car was among the 16 cars still running at the end.
