  • Running costs manageable
  • Discontinued diesel is the economy winner
  • TwinAir not as frugal as expected

Running a Fiat 500 won’t cost you an awful lot, no matter the model you end up buying. While prices are reasonable to start with, it holds its value well and the engines are largely frugal – at least on paper.

The 69hp 1.2-litre petrol claims to return up to 50.4mpg – a figure that should be perfectly achievable even when driving the 500 relatively hard.

The two-cylinder TwinAir, meanwhile, claims up a maximum of 51.4mpg on average, although you may have trouble of achieving it. If you’re pootling around town and not fussed about making moderately quick progress anywhere, you might get more than 50mpg. But as soon as you need to keep up with traffic on a slightly faster road, it’s easy to see the average fuel economy figure slip below 40mpg.

It’s also easily done simply by having a bit of fun – the growly engine note is quite infectious so you could find yourself driving everywhere in second gear just for the raspy sound of it. Just don’t expect to get anywhere near those on-paper figures.

Is the Fiat 500 eco-friendly?

Carbon dioxide (CO2) emissions are impressively low across the whole 500 range – at its worst the little Fiat emits no more than 116g/km, which is for the manual 1.2-litre petrol. The 85hp TwinAir produces 106g/km.


Fiat doesn’t possess the greatest reliability record for many of its cars, but the 500 in manual form is proving dependable enough. Unfortunately the 500 has been the subject of 10 recalls in its life so far – many of which are shared with the Panda. Many relate to the issues with brakes, steering and seat belts, and all should have been sorted out under Fiat warranty when the recall was originally issued.

Ensure that any recall work has been carried out if you’re looking at buying a used 500, and if you’re buying a new one, we hope that any big issues will have been ironed out. If you do encounter anything, Fiat’s three-year warranty will cover you.
