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 - 51 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.

The biggest burden for the new buyer is depreciation - the 2001-2004 C5 performed poorly against rivals - particularly in petrol forms, but as the car ages, this is becoming less of an issue for buyers. Diesels offer excellent fuel economy and petrols compare well to rivals. However, a diesel estate will be easier to sell on and won't depreciate as quickly as other models.

Service intervals are well spaced and Citroën dealers generally offer good value for money. Insurance groups are 8-14.

C5 is an environmentally friendly choice for green buyers. With an average of 174 g/km CO2 across the range, its emissions are quite low for a medium-sized estate. However, it's worth noting that the line up has a high number of diesel models, bringing the average down and giving buyers more choices of low-emission versions. Diesels typically produce less CO2 than petrol engines with similar power outputs.

Eco-conscious buyers should consider the 1.6-litre diesel, which is one of the greenest models in the range. The range is also fairly economical, averaging 43 mpg.

The 2004 C5 should have had many of the defects that have annoyed owners ironed out. Time will tell. However, there are still too many unexplained creaks and rattles for true peace of mind, and vehicles we have tested have displayed warning messages relating to the car's electronic systems.
