Ferrari bounced back and forth between two different classes in order to create the most competitive sports car on the market. This goal became quite difficult when the sport’s governing body decided to change the rules back in 1968.
Prototypes could only be made by a three-litre displacement limit and a new class of limited production GT cars with a maximum displacement of five litres was created. To be homologated for the GT-class at least 50 examples needed to be constructed, but from 1969 that number was reduced to 25.
New European legislation on noise and pollution forced Ferrari Company to make major modifications to the 365 BB and so, in 1976, the 512 BB was born. Exterior changes included larger wheels, a new front spoiler and extra cooling ducts, while the engine was enlarged to nearly 5 litres.
