Ferrari 400 Automatic i

The 400 Automatic i succeeded the 400 Automatic in November 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 fuel injection system used was Bosch K-Jetronic, and concurrently a single distributor mounted at the right rear of the engine, with a Dinoplex electronic ignition system, replaced the earlier twin distributor layout.

The 400 Automatic i was initially visually identical to its predecessor both internally and externally apart from the addition of an “i” to the tail badge, although the tubular steel chassis type reference number became F 101 DL 170.

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 bhp, and the hydraulic self levelling rear suspension changed to a gas filled system, coupled to new metric rim wheels with lower profile tyres.

Internally there were revisions to the upholstery stitching pattern, door panel design, and centre console layout.

Outside the door mirrors became more elegant with small enamel Ferrari shields on their casings, the width of the radiator grille was reduced to expose the driving lights, which became rectangular instead of square, the radiator exhaust air louvre in the bonnet became body colour, and high intensity fog lights were set into the rear bumper.
