Reliability, common problems and owner reviews for the Fiat 500 0.9 TwinAir (turbo 2-cyl). Check this before you buy used.

The 0.9 TwinAir two-cylinder turbo is full of character and clever (MultiAir electro-hydraulic valves), but it's the 500 engine that demands respect: it can use noticeable oil, the MultiAir actuator unit and timing chain want clean correct-spec oil, and real-world economy rarely matches the lab figures if driven with any verve. A documented, oil-disciplined car is enjoyable and fine; an unknown-history one that's been run low on oil is a gamble. Many buyers prefer the simpler 1.2.
