Giannini creates insane Fiat 500-based 350 GP4

The Fiat 500 range is pretty wide – with basic, 1.2-litre models producing a measly 69bhp right up to the insane Abarth 695 Biposto, which shoves out a massive 187bhp. However, Italian aftermarket tuner Giannini has taken this up a notch with a truly insane set of modifications – producing the 350 GP4.

An evolution of the existing 350 GP, the GP4 is totally overhauled from the standard 500. The engine is taken directly from the Alfa Romeo 4C sports car, which means it's a 1.75-litre, turbocharged four-cylinder. However, Giannini has tuned it to produce a massive 345bhp.
