Citroen C4 review - MPG, CO2 and running costs

With a choice of petrol, diesel or all-electric powertrains, the C4 offers great flexibility

While the C4 is competitively priced, with a bit of determined haggling you should still be able to negotiate a discount with your Citroen dealer. With no plug-in hybrid tech on offer, it’s a straight choice between petrol or diesel power, or the all-electric e-C4 model.

Citroen claims all C4 petrol cars are capable of pushing past 50mpg on the combined cycle, with the exception of the 153bhp variant which still manages to return up to 48.8mpg. CO2 emissions range from 120g/km to 134g/km, which gives a Benefit-in-Kind (BiK) tax rate of 28-30 per cent for business users. 

During our own test with a 128bhp PureTech petrol (six-speed manual) version we struggled to match the manufacturer’s economy figures, achieving just 37.4mpg. Even allowing for variables such as different driving styles, road types and weather conditions, this is a disappointing real-world result.

A company car driver covering more miles may be better served with a C4 diesel version, as the claimed fuel economy figure climbs to over 60mpg, while the BiK tax rate falls to 26 per cent. Although more expensive to buy, the all-electric e-C4 offers a 217-mile range and zero CO2 emissions, which again could attract business users keen to reduce their tax bill.

Insurance groups

The entry-level C4 1.2 PureTech Sense version sits in group 13 for insurance, while the top-spec 153bhp Shine Plus petrol variant is in group 22. In comparison, the Kia XCeed petrol range starts from group 12, rising to group 19 for a 158bhp ‘4’ model.

Insurance premiums won’t be particularly affected if you go for a C4 with a diesel engine, as all of the oil burners sit in groups 16 to 21.

Depreciation

Citroen cars don’t typically have a reputation for holding their value on the used market, although the C4 bucks this trend with its fresh styling, good levels of standard equipment and keen pricing helping residuals stay pretty strong. 

Our data suggests that, after a three-year/36,000-mile period of ownership, the C4 should hold onto around 48-53 per cent of its original list price, with the entry-level versions performing the best. The all-electric e-C4 is an equally sound bet with a forecast of 54 per cent retained over the same period.
