The Ferrari 400i, produced from 1979 to 1985, marked a significant departure from the traditional Pininfarina-designed Ferraris. This grand tourer, characterized by its sleek, angular bodywork, was the brainchild of Leonardo Fioravanti, then a prominent designer at Pininfarina. The 400i, a successor to the 365 GT4 2+2, boasted a sportier profile with a lower roofline and a more prominent front grille. This stylistic shift aimed to attract a new generation of buyers seeking a balance between luxury and driving performance. Beneath the redesigned exterior resided a powerful 4.8-liter, 90-degree V8 engine, producing 310 horsepower and offering a thrilling driving experience. The 400i was available in both manual and automatic transmission configurations, catering to diverse driving preferences. Notably, this model introduced the "i" nomenclature, signifying the application of Bosch K-Jetronic fuel injection, a cutting-edge technology for its time.

The Ferrari 400i was not merely a powerful machine but a statement of luxury and exclusivity.
