Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 28 - 64 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

Citroens have a reputation for suffering harsh depreciation and the C4 is no better. Insurance groups are reasonable and fuel consumption from the diesels is impressive while Citroen servicing is usually good value, even if the dealers don’t fare well in customer service surveys.

The C4 Coupe scores very well on the eco front with the greenest engine the 1.6-litre HDi with 92bhp. This emits 117g/km of CO2 making it cheap to tax, while fuel economy is an impressive 64mpg.

This hasn’t previously been one of Citroën’s strongest areas and the low rent feel of the interior, poor switchgear and doors that ‘clang’ shut do little to inspire confidence. Since its launch there have been a string of problems reported from owners which goes against Citroen’s claims to have improved reliability and quality
