The 365 GT4 BB was updated as the BB 512 in 1976, resurrecting the name of the earlier Ferrari 512 racer
The name 512 referred to the car's 5 liter, 12 cylinder engine; a deviation from Ferrari's established practice of naming 12-cylinder road cars (as the 365 BB) after their individual cylinder displacement
The engine was enlarged to 4943 cc, with an increased compression ratio of 9.2:1. Power was slightly down to 360 hp, while a dual plate clutch handled the added torque and eased the pedal effort
External differentiators included a new chin spoiler upfront, incorporated in the bumper. A NACA duct on the side provided cooling for the exhaust system. At the rear there were now twin tail lights and exhaust pipes each side, instead of triple units as on the 365 GT/4 BB.
