The Ferrari 400 i, produced from 1979 to 1985, represents a significant departure from Ferrari's purist sports car image. As a grand tourer with fuel injection (hence the 'i'), the 400 i offered a more comfortable and refined driving experience. For New Zealand enthusiasts considering importing or restoring one, understanding its specific quirks and maintenance needs is crucial.
Common issues include fuel injection problems (related to the age of the system and the degradation of rubber components), cooling system inefficiencies leading to overheating, electrical faults, and corrosion in the exhaust system. The self-leveling rear suspension can also be problematic and expensive to repair. Regular servicing of the fluids and filters is key.
A WOF inspection should pay particular attention to the braking system, ensuring all calipers and rotors are in good condition. Check the condition of the suspension components, including the rear self-leveling system. Ensure all lights are functioning correctly, and that the tires are of the correct specification. Exhaust emissions must also meet legal requirements, which can be challenging with older fuel injection systems.
The 400 i boasts a sophisticated (for its time) Bosch K-Jetronic fuel injection system coupled with Ferrari's signature V12 engine. This combination, while potent, demands meticulous maintenance. The automatic transmission, though providing ease of use, can be a source of problems if not properly serviced with correct fluids. Suspension components are complex and expensive to replace. The interior trim also requires special leather care.
