• One of the more efficient choices in the class
• It meets all current emissions standards
• PHEV obviously takes the efficiency crown

What are the running costs?

If you’re after the most economical non-hybrid C5 Aircross, then you’ll unquestionably head towards the 130hp BlueHDi diesel, which Citroen claims delivers over 55mpg in official testing. However, our long-term experience in a similarly-engined Peugeot 5008 places that nearer to 50mpg in real-world driving. CO2 emissions are competitive, though.

The petrol-powered 1.2 Puretech is impressively efficient for a small engine in a big car. Official fuel economy in the mid-to-high 40s will be more like low-to-mid 40s in the real world, which is perfectly acceptable in our book.

The Hybrid 136 model splits the difference between BlueHDi and Puretech. WLTP fuel economy is listed as 53.3mpg and we’ve seen 50mpg in our testing. Though it will dip into the low-40s if you get a shift on.

Lastly, there’s the C5 Aircross Plug-in Hybrid. This potentially has the best fuel consumption of all, but our long-term test C5 Aircross didn’t get close to the advertised figures – usually the case with a PHEV. We saw around 38.5mpg in mixed use, which included motorway mileage, and we really weren’t thrashing it.

The fuel economy of the plug-in hybrid very much depends on how often you charge it. It’s capable of around 25-30 miles on a full charge in the real world, which should be enough to cover the majority of daily commutes and midweek trips. It also means that, provided you charge up regularly, you’ll rarely need the engine. The flip side is that if you don’t charge it at all, it’ll likely be the least efficient model in the range.

Servicing and warranty

The C5 Aircross has a three-year warranty, with an unlimited mileage cap in the first two years and a 60,000-mile cap in the third year. You can also extend the warranty if the car has done less than 100,000 miles and is less than 10 years old.

Citroen offers a servicing package that you can pay for up front that lasts up to three years or 35,000 miles. It’s available for the first year from when the car is registered.

Reliability

• Based on a proven parts bin
• Citroen’s reliability much improved of late
• Five 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. That’s a good thing, as the latest crop of models from those brands have been far more reliable than some of their predecessors.

Despite this, the C5 Aircross has been subject to five official recalls. These range from rather trivial issues such as replacing the bolts on the optional trailer hitch, to the more serious such as the emissions control system on diesel models.

We didn’t experience any reliability issues with our long-term test car. However, a few gremlins have cropped up in more recent testing, for instance non-functioning parking sensors.
