The Ferrari 400 - Automatic (a/k/a 400 A) was the first Ferrari to be produced with an automatic transmission. Along with the Ferrari 400 - Manual, the 400 is the second iteration of a series of cars that included their predecessor, the 365 GT4 2+2, and the subsequent Ferrari 400i and the Ferrari 412. Made between 1977 and 1979, the 400 A was powered by the same V12 as its predecessor, but received a slight displacement increase to 4.8 liters (as compared to 4.4 liters). The V12 used six side-draft Weber carburetors, and was capable of 335 HP at 6200 rpm, sending drive to the rear wheels through a GM 3-speed automatic transmission. Ferrari produced a total of 502 samples of the Ferrari 400, out of which 355 were automatic and the rest were manual. It evolved into the Ferrari 400i - Automatic in 1978.
