Oemmedi Meccanica has built probably the craziest Fiat 500 on Earth. Sure this is more of an engine mashup than a true engine swap but something like this deserves attention. This Fiat has had two previous engine swaps, the first being a 3.2L Porsche flat-six and the next was a 3.0L Ferrari V8. Now the small car has a 580 horsepower 6.2L V12 from a Lamborghini Murcielago.
