Ferrari 512 BBi

Bosch K-Jetronic mechanical fuel injection on the 512 BBi replaced the outgoing model’s four, triple-choke Weber 40 IF 3C carburettors. Otherwise mechanically identical, the flat-12 featured lower maximum revs (6,600 rpm compared to the 512 BB’s 6,800 rpm) and the engine developed 20 bhp less, although top speed remained within a whisker of the 512 BB’s 283 km/h.

The 512 BBi was introduced at the 1981 Frankfurt Salon, to replace the 512 BB model, the “i” suffix denoting a change from carburettors to fuel injection. Apart from the adoption of fuel injection, in line with the other models in the Ferrari range at the time, there were minor cosmetic and mechanical changes. The standard road wheels were alloy five spoke “star” pattern, with a knock off spinner on a Rudge hub, although legislative requirements in some markets dictated the fitment of a large octagonal hub nut. The wheels covered large ventilated disc brakes with twin hydraulic circuits, and servo assistance. Independent suspension was provided all round, via wishbones, coil springs, and hydraulic shock absorbers, with twin rear units, together with front and rear anti roll bars.
