In the case of the 500 PUR-O2, Fiat equipped the 1.2 petrol engine with its new Start&Stop system that turns the engine off temporarily and restarts it during periods when the engine would be idling with the car at a standstill. According to Fiat, this system alone can cut fuel consumption by as much as 10 percent over an urban cycle. In terms of CO2 emissions, the PUR-O2 version of the 500 boasts a low figure of 115 gr /km. Further details on the 500 PUR-O2 will be announced at the Paris Show.
