History of the Ferrari 400
Ferrari premiered the 400GT, the successor for the 365 GT4 2+2 at the 1976 Paris Motor Show. The updated 400 was available in two models: the 400 Automatic, which used a GM THM400 three-speed automatic transmission, and the 400 GT, which used a five-speed transmission.
The Ferrari 400 Automatic was the first Ferrari to use an automatic transmission. The 365's V12 engine had been expanded to 4.8 L and given six 38 DCOE 110-111 Webers, producing 340 PS. 0-60mph took 7.1 seconds. Other differences from the 365 GT4 2+2 were five-stud wheels to replace the knock-off hubs (Borrani wheels were no longer supplied), a reworked interior, the introduction of a lip to the front spoiler, and double circular taillights.

The 400 and 400i were first distinguished by a fuel-injected engine and an "I" emblem on the rear. In 1979, Bosch K-Jetronic fuel injection replaced the 400's carburettors. Power was reduced to 306 hp, the same as in the smaller 308GTBi and 308GTSi, but emissions were much improved, meeting US requirements. The fastest speed recorded was (149 mph).
The 400i was modified at the end of 1982. Engine power was increased to 315 PS thanks to new camshaft profiles and exhaust headers. The interior was extensively updated, with new upholstery, door panels, centre console, and electrical switchgear. A smaller grille revealed the rectangular fog lights on the outside, and the venting on the engine hood was changed from silver to body colour. New, more stylish wing mirrors with a tiny Ferrari shield were installed. The rear panel was body-coloured rather than matte black, and foglamps were installed in the bumper.
