Size matters. And for Fiat, it's a case of the smaller the better with its new TwinAir 900cc two-cylinder engine. On the outside, there's little to distinguish the two-cylinder Fiat from any other 500, but as soon as you turn the ignition key, it's clear that there's a very different powerplant under the bonnet.
Thanks to Fiat's MultiAir technology, and the addition of a turbocharger to improve performance, the TwinAir is not only deceptively fast but, with CO2 emission of 95g/km, it's also the world's least polluting petrol car.
To prove that a car can be both fun and frugal at the same time, we brought the TwinAir together with the fastest Fiat 500 money can buy - the fearsome Abarth. But if you think the Abarth is bound to deliver more thrills, think again.
Watch our exclusive video to find out if the underdog can come out on top in our very own version of David vs Goliath.
