This is Mauro Forghieri's Ferrari 312 B3 from late 1972, better known as the Spazzaneve (snowplow) was dubbed "too ugly to race". Fast Forward a few years in to the future and F1 fans get to see the wedge-concept in action and can also hear the flat-12 wail has to offer!!
Even after Mauro Forghieri left the Ferrari team just before the Ferrari 312 could ever run, but a year later Forghieri joined them again and went on to win multiple championships.
Listen to the beautiful sound this "ugly" Ferrari makes below!
