  • All variants are economical compared with rivals
  • It meets all current emissions standards
  • PHEV obviously takes the crown

If you're after the most economical regular C5 Aircross, then you'll unquestionably head towards the 130hp BlueHDI diesel, which Citroen claims delivers up to 55.1mpg in official testing – although our long-term experience in a similarly-engined Peugeot 5008 places that nearer 50mpg in real-world driving. The CO2 emissions of 137g/km is competitive.

The BlueHDi 180 is much more usable on the road, and feels positively rapid compared with the 130hp car. Despite the improvement in performance, it still delivers 47.1mpg claimed in the official combined mpg test.

The petrol-powered PureTech model will be economical and sprightly enough for most drivers, though. Especially if they're looking to get out of diesels. The 130hp version is claimed to return 44.2mpg, with 149/gkm CO2 emissions.

Plug-in hybrid fuel economy

The fuel economy of the plug-in hybrid very much depends on how you use it and namely, how much you charge it.

It's capable of up to 40 miles on a full charge, which should be enough to cover the majority of daily commutes and midweek trips. This means that provided you charge up regularly, you might not need to trouble the petrol engine at all.

Naturally the reverse is true if you exclusively run off petrol power and don't ever plug in to the mains.

Of course, Citroen can't write that down in a brochure, so it returns official economy figures of up to 222.3mpg and 32g/km of CO2.


  • Based on a proven parts bin
  • Citroen's reliability much improved of late
  • Two official recalls affect specific models

The Citroen C5 Aircross is based on the same basic parts bin as almost every current Peugeot, Citroen, DS and Vauxhall product. This is a good thing, as the latest crop of models from the brands have been far more reliable than some of their predecessors.

Despite this, the C5 Aircross has been subject to two official recalls. The first concerned the bolts that hold on the optional trailer hitch, while the other concerned the emissions control system on diesel models.
