Whether it's Mozart, Beethoven or The Beatles, they all (arguably) pale in comparison to just the right engine note for many auto enthusiasts. Petrolicious has found one of the absolute best with its latest focus on a 1972 Ferrari 312PB. The 312PB is important for more than just its ability to sound like an automotive symphony. It was also the final purpose-built prototype racer of the era from Ferrari before the Prancing Horse put its entire focus into Formula One. Maranello went out with a bang, though. The 312PB's design is simplicity itself with just a modified wedge shape combined with the necessary scoops and ducting to keep its 12-cylinder engine at full tune. The car won a string of races and scored the 1972 championship. Although even if it had been a loser, the racecar likely would have been famous just for its wonderful exhaust note. In the video, Petrolicious expertly balances its interview with owner Steven Read with wonderful cinematography and just letting the Ferrari sing around the Willow Springs track.
