Dominating the 1972 Manufacturer’s World Championship and driven by such legends as Mario Andretti and Jacky Ickx, the 1971 Ferrari #2 Ferrari Automobili 312 P holds historic status in endurance racing. The car was developed in response to the FIA’s decision to limit engine displacement to three liters, down from five. Despite the belief the car used a further-developed F1 V12; it was powered by a horizontally opposed 12-cylinder boxer engine with twin overhead cams for each bank of cylinders. The boxer engine reduced the overall height, as well as the car’s center of gravity. Developing 440 bhp at 10,800 RPM and weighing in at just over 1,400 pounds, the 312 P had a formidable power-to-weight ratio of .316. The cars distinctive post-mounted rear-view mirror and wedge-scoop design set it apart from its contemporaries, just as pork chops and sideburns did with facial hair of the era.
