While the little Fiat 500 is already a fuel-sipping teetotaler, Fiat obviously felt it could do better.
The Italian carmaker has whacked a start/stop system into the ?Bambino? Fiat 500, which ? as with other start/stop systems ? deactivates the car?s engine while at a complete stop, reactivating it when the driver engages the clutch and selects a gear before taking off again.
Fiat claims that fuel economy for city driving jumps from 6.4 l/100km (44.1mpg) to 5.7 l/100km (49.6mpg). If that?s not good enough for you, perhaps the combined cycle figures ? which shift from 5.1 l/100km (55.4mpg) to 4.8 l/100km (58.9mpg) ? will be more to your liking.
CO2 emissions also drop from 119g/km to 113g/km.
Fiat?s Start&Stop system will be fitted to the 1.2 litre petrol engine. There?s no word yet on whether it will appear on the 1.4 litre petrol or 1.3 litre JTD diesel engines.
Enthusiasts might want to wait until later this year, however, when Fiat launches its first dual-clutch transmission. It will initially appear in the Alfa Romeo MiTo, before filtering through to the rest of the Fiat range.
