Video: The Ferrari 312 PB was mightier than the 512!

So here it is, the final prototype sportscar that Ferrari would ever build to race in a world championship. It followed the legendary 512, and despite being much less famous, was much, much more successful. In fact in 1972 the Ferrari, powered by a sonorous V12 derived from the firm's contemporary F1 contender, won every race in which it was entered (they skipped Le Mans that year).

But 1973 didn't go quite so well. They were beated by Matra at both Le Mans and in the championship, marking the end of Ferrari in the WSC. The company, once the dominant force at Le Mans – a race which Enzo considered one of the most important around – took the decision to focus on its dwindling F1 chances, and that was that for the Prancing Horse at Le Mans.

Thankfully some of the cars are still alive, and our friends at Petolicious have put together this awesome film detailing one of the finest examples. Just listen to it howl.
