Citroen C5 Aircross review - MPG, CO2 and Running Costs

Smaller petrol and diesel engines offer a competitive blend of fuel efficiency and performance

The fuel economy champion of the Citroen C5 Aircross range is the 1.5 BlueHDi 130 diesel, which returns a maximum 56.3mpg when paired with the eight-speed auto. The six-speed manual is slightly down on this figure at 55.1mpg, with CO2 emissions from 137g/km for both. There is also a larger diesel, the 2.0 BlueHDi, which returns 47.1mpg and emits 164g/km.

If you opt for petrol power, the PureTech 130 engine returns a claimed 45.2mpg and emits 154g/km of CO2, when combined with the eight-speed auto - not quite on a par with the diesels, but still offering a decent blend of economy and performance. 

Those looking for the the best economy return will be best served by the new C5 Aircross Hybrid. It uses the PureTech 180 engine, but with an electric motor sandwiched between the power unit and the eight-speed automatic gearbox. Citroen claims it will give an all-electric range of around 30 miles, with emissions of 33g/km (awaiting approval).

Insurance groups

Insurance groups for the C5 Aircross are reasonable, ranging from group 16-19 for the diesels, and 17-25 for the petrol-powered cars. 


Citroen has a history of offering dealer incentives and discounts, which should mean the car can be had with an appealing monthly finance rate. This is, in some respects, a safer way into an Aircross than outright purchase, because it insulates you from depreciation – a factor that has not been particularly kind to Citroens in years gone by.

As it competes in one of the most hotly contested segments of the new-car market, the C5 Aircross is inherently desirable, helping maintain values, particularly to those keen on its unique selling points of comfort and design. Even the entry-level Feel model is well equipped, so the outlay needed to get a decently specified model is also reduced. Expert data predicts the C5 Aircross will retain an average of 45% of its value over 3 years and 36,000 miles.
