History of the Ferrari 400i
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).
