The Ferrari 400, introduced at the 1976 Paris Motor Show, was the successor to the 365 GT4 2+2 and Ferrari's first model to offer an automatic transmission, the 400 Automatic, with a GM THM400 3-speed. An alternative, the 400 GT, came with a five-speed manual transmission. This model featured a 4.8-liter V12 engine with six 38 DCOE 110-111 Weber carburetors, producing 340 PS, achieving 0–60 mph in 7.1 seconds. Notable changes from the 365 GT4 2+2 included five-stud wheels replacing knock-off hubs, updated interior, modified front spoiler, and double circular tail lights instead of triple. Of the 502 units produced, 355 were Automatics and 147 were GTs.
