MPG, running costs & CO2 Rating

4.0 out of 5

The Citroen C3 Aircross uses small engines designed first and foremost to be affordable to run, so shouldn’t put a dent in your wallet. The best fuel economy comes from the manual models, though, so you should expect to spend a little more on fuel and company-car tax if you go for an automatic.

Citroen C3 Aircross MPG & CO2

The 1.2-litre PureTech petrol engine is most efficient in its smaller 109bhp guise, returning up to 51.5mpg with stop-start fitted. Opting for the more powerful 128bhp version sees fuel consumption rise to 47.3mpg, while the 81bhp version is no longer available and didn’t get this fuel-saving technology, so returned a lower official economy figure. With CO2 emissions of between 141-154g/km, the less powerful 1.2-litre petrol engine models fall into reasonable BiK bands for business users.

The BlueHDi diesel is the most economical, returning up to 62.7mpg, but it’s also considerably more expensive to buy than the petrol, so is best suited to drivers with a high annual mileage. Emissions of 126-137g/km of CO2 place the diesel Aircross in good BiK bandings.

After the first year's CO2-based road tax (generally included in the on-the-road price), all versions of the C3 Aircross cost £150 a year to tax.

Insurance groups

Insurance groups for the C3 Aircross are as low and affordable as you might expect, spanning from group 9 to 20 out of the 50 available.


New Citroens come with a standard three-year/60,000-mile warranty that can be extended by a few years for additional cost at the time of purchase. This is on a par with SEAT, but rivals like Kia are better, with an industry-leading seven-year warranty, while Hyundai covers the Kona for five years or 100,000 miles.


Citroen offers servicing plans that allow you to budget for maintenance costs by paying for two or three services in monthly installments. Contact your local dealership for the latest prices and offers.
