While the more sporting Ferraris adopted a mid-engine layout, the large 2+2 cars retained the front V-12 in ever-larger size. The same basic car was produced from 1972 to 1989 in the following versions:
-- 365GTB4 2+2 1972 to 1976 with 521 built
-- 400 1976 to 1979 in with 4.8-liter V-12 in two variants: the 400GT with 5-speed manual transmission and the 400A fitted with a General Motors-sourced three-speed automatic transmission. 147 400GTs were built and 355 400As were built. The 400 was the luxury Ferrari but the sales of so many automatics horrified some hard-core Ferraristas, but Ferrari was giving the customers what they wanted.
-- 400i with fuel injection from 1979 to 1984; 1,305 were built and the automatic sales were nearly twice that of the manual cars.
-- 412i with enlarged 4.9 engine from 1985 to 1989. 576 cars were built and the manuals showed a slight resurgence but were still outnumbered by automatic versions. Late models had ABS. Metric-sized Michelin TRX 240/55R-415 tires were fitted to late 400I cars as well as the 412i. Many subsequent owners have refitted non-TRX tires as the years have gone by.
