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 diesel, which returns a claimed 68.9mpg – and that’s regardless of whether you opt for the six-speed manual gearbox or the eight-speed auto. CO2 emissions are 108g/km and 107g/km respectively. There is also a larger diesel, the 2.0 BlueHDi, which returns 58.9mpg and emits 126g/km.

If you opt for petrol power, the PureTech 130 engine returns a claimed 55.3mpg and emits 121g/km of CO2 – not quite on a par with the diesels, but still offering a decent economy and performance blend in other PSA Group cars we’ve tried. The more powerful PureTech 180 petrol is, as you might expect, the least efficient of the range. 

However, if you’re not in a hurry, from early 2020, the C5 Aircross will be available as a plug-in hybrid. This 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.

Insurance groups

Insurance groups for the C5 Aircross are still being calculated. However, we’d expect them to start around group 11 for the lower-powered diesels, and 16 for the petrols. Top-spec models will probably sit in group 22 or 23.


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.
