As for the 400 Automatic, the 4000 GT also got an "i" version in 1979. The "i" suffix in the model name standing for "injection", as a fuel injection system replaced the two banks of three side draught Weber carburettors. The 400 GTi stayed in production from 1979 to 1985, with 422 units produced in both right and left drive steering configuration, but with no USA market version was available.

Under the hood Ferrari placed a V12 unit with a bore and stroke of 81mm x 78mm giving a total capacity of 4823cc, with factory type reference number F 101 D 010, coupled to a Borg Warner 3 speed automatic gearbox. This transmitted power through a propeller shaft to a limited slip differential, and from there via half shafts to the independently suspended rear wheels with hydraulic self levelling units. The engine delivered 310 HP, while top speed went up to 152 mph.

The 400 GTi was initially visually identical to its predecessor both internally and externally apart from the addition of an "i" to the tail badge. In late 1982 some mechanical and cosmetic changes took place to the model. The engine received revised profile camshafts and new exhaust manifolds, which upped the power output by about 5 HP, and the hydraulic self levelling rear suspension changed to a gas filled system, coupled to new metric rim wheels with lower profile tyres.
