Parkers overall rating: 4.1 out of 5 4.1
  • All variants are economical compared with rivals
  • It meets all current emissions standards
  • No PHEV version until 2020

If you're after the most economical C5 Aircross, then you'll unquestionably head towards the 130hp BlueHDI diesel, which Citroen delivers up to 70.6mpg in official testing – although our long-term experience in a similarly-engined Peugeot 5008 places that nearer 55mpg in real-world driving. The CO2 emissions of 106g/km is competitive, and means company car drivers get a low-ish 26% Benefit-in-Kind (BiK) tax rating.

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 60.1mpg 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 54.4mpg, with 122g/km CO2 emissions (call it 42mpg in real-world driving), while the 180 auto makes 49.6mpg and 129g/km (call it 38mpg in the real world).
