In my experience Fiat engines have always been great. It’s the bits surrounding them which usually account for the demise of the car! The images below are two I’ve owned, Uno Fire & Bravo HGT, but the awards went to the amazing 875-cc TwinAir mill in the “500” and the Ferrari 458's 4.5-litre V8. One day I’d like to own those two!
