The official fuel economy of the now defunct DS 5 in Hybrid4 spec is practicality unprecedented in a car of its size and in its segment. A claimed 83.1mpg is on offer alongside an official CO2 rating of just 88g/km.

However, buyers should note that the real-world economy figures are likely to be somewhat removed from these figures. A real-world 60mpg is quite easily achieved, but while good, that's nothing like as exceptional as you might hope.

The DS 5 undercuts an equivalent Mondeo Estate

The standard 2.0-litre HDi model is also impressively economical – both on paper and in the real world; in an extended run, we achieved 55mpg on our touring route and 42.8mpg overall. That may be some way behind the official combined figure of 55.4mpg, but it’s more than competitive.

The range-topping 205bhp 1.6 THP turbocharged petrol option that’s smooth and eager, but it only makes financial sense if you don't cover many miles or don't pay for your own fuel.

While it doesn’t represent the value for money that a familiar big Citroën would, the DS 5 is at least well priced. At full list, near-range-topping models undercut an equivalent Ford Mondeo Estate. And though it can’t compete with the Ford on practicality, it out-dazzles it by a country mile.

Residual values will depend on how much demand there is for the DS 5 and how cleverly Citroën’s dealers manage that demand. Our experts suggest they will be strong – not quite to premium brand levels, but much better than usual for Citroën. Business demand for the emissions-efficient Hybrid4 version should help, too.

However, discounted DS 5s are being offered through familiar channels, sowing a seed of doubt about the ability of Citroën’s dealer network to effectively sell a big, premium-priced car. Which means private buyers must push for discounts to be sure of getting value for money.
