Citroen C5 Aircross review - MPG, CO2 and running costs

Those looking for the the best economy should look to the C5 Aircross plug-in 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).

The 1.5 BlueHDi 130 diesel also offers impressive fuel economy, returning a maximum 60.8mpg when paired with the six-speed manual 'box. The eight-speed auto is slightly down on this figure at 57.8mpg, with CO2 emissions from 129g/km and 136g/km respectively. The 2.0 BlueHDi is no longer available, but was able to deliver 47.1mpg, with CO2 of 164g/km.

If you opt for petrol power, the PureTech 130 engine returns a claimed 49.5mpg and emits 140g/km of CO2, when combined with the six-speed manual transmission. There is a slight efficiency penalty if you opt for the eight-speed automatic which is capable of a WLTP combined figure of 46.7mpg, with CO2 emissions from 147g/km.

Insurance groups

Insurance groups for the C5 Aircross are reasonable, with petrol and diesel models ranging from group 18-19 (out of 50). Premiums for the more powerful plug-in hybrid versions will be more expensive as they sit in group 28.

Depreciation

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. Expert data predicts the C5 Aircross will retain an average of 51 to 54 per cent of its value over three years and 36,000 miles.
