Heavily modified Fiat 500 has a Lamborghini V12 engine [video]


Probably the most powerful Fiat 500 in the world

The Italian engineers at Oemmedi Meccanica have been working for quite some time on a classic Fiat 500http://images.intellitxt.com/ast/adTypes/icon1.png, fitting it with several powerful engines.
This old Fiathttp://images.intellitxt.com/ast/adTypes/icon1.png 500 has a very interesting story to tell as over the course of its life was powered by a 3.0-liter V8 engine from Ferrari and 3.2-liter flat-six taken from a Porsche Carrera. More impressively, the Fiat 500 is able to host a huge 6.2-liter V12 engine sourced from a Lamborghini Murcielago producing 580 bhp (432 kW).
Just as impressive is the Volkswagen Golf I by Boba Motoring we talked about a month ago, packing a 736 HP (541 kW) 2.0-liter 16V engine featuring a Garrett GTX3582R turbocharger
As you would imagine, handling the petite, massively-powered classic Fiat 500 is not for everyone. Here is a video with the V12-powered Fiat 500's soundtrack and its retractable rear spoiler.
