Ferrari built upon the success of the 365 GT4 Berlinetta Boxer beginning in late 1976 with the introduction of the 512 BB. The name reverted to Ferrari’s more typical liters/cylinders nomenclature; the new 512 featured a small chin spoiler in front, exposed driving lights, rectangular rear parking lights, NACA ducts on the lower body sides ahead of the rear wheels, four taillights (in lieu of six), and a tail 1½-in. longer. It offered the advanced and reliable Bosch K-Jetronic fuel-injection system for the first time in a 12-cylinder Ferrari, hence the “i” in its nomenclature.
For the Ferrari faithful, the addition of the fuel injection was a welcome change, and the 512 BBi is generally considered to be the most civilized of Ferrari’s Berlinetta Boxers. The change from carburetors to fuel injection brought about an increase of 20 foot-pounds of torque, helping the engine to feel much more tractable overall. Performance remained extraordinary, and the 512 BBi could reach 60 mph from a dead start in just 5.4 seconds, leading to an estimable top speed of 174 mph. By the time production came to an end and the 512 BBi was replaced with the Testarossa, Ferrari had built just 1,007 examples. The example offered here has traveled 25,107 miles from new and is offered with its original books. It remains an important and collectible Ferrari.
