FERRARI400i 1979 - 1985

　　As emission regulation got stricter, in 1979, the Ferrari 400 got an updated engine. Instead of the 6 carburettors, the V12 received a Bosch K-Jetronic fuel injection system.

　　This meant a greater improvement regarding emissions but it took the power down from 340 HP to 310 HP.

　　The later models featured different camshaft profiles and exhaust headers, thus the car got 5 extra HP.

　　The car featured a 4.8-liter V12 engine that was able to rocket the car to 100 km/h in 8.2 seconds. The engine boasted 311 hp and had a maximum torque of 412 nM. The power was delivered to the wheels through a 3-speed automatic gearbox. The official top speed was rated at 235 km/h.

　　While the exterior suffered minimal visual changes, like the “i” badge on the tail, the interior was refreshed and got a new upholstery, along with new door panels and an electronic switchgear.

　　The model retained the standard 5-speed manual (400i GT) and the optional 3-speed automatic gearbox (400i Automatic) or a 5-speed manual transmission. A total of 1,305 units were made.

　　Due to the America’s smog and safety regulations, the 400i never made it onto their market.

　　The 400i was replaced in 1985 by the Ferrari 412, with minor changes to the exterior and a slightly bigger engine, a 4.9-liter developing 340 hp.
