Why the one and only? Because the Fiat 550 Italia prototype with the Ferrari F136FB V8 engine will only be built. The reworked Fiat 500 was signed by Lazzarini design, which moved the engine to the rear end, and the monstrous machine gave space to the entire rear part of the car, including the rear seat bench. Compared to the serial model, the wheelbase has been stretched to 2,650 millimeters instead of 2,300, and of course everything else on and inside it testifies to the fact that it is not a normal model.
