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 45 - 72 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.

Following the round of mechanical enhancements introduced at the 2015 rebrand, DS 5 running costs are reduced compared to the previous Citroen version.

Most expensive in terms of running costs is the 1.6-litre THP 165 petrol engine, with an official average consumption claim of 47.9mpg and CO2 emissions of 136g/km.

Conventional diesel power plants are likely to form the majority of DS 5 sales, with the 1.6-litre BlueHDi 120 being the least expensive to run with average consumption claims of 70.6mpg and CO2 emissions of just 104g/km.

Most frugal is the diesel-electric Hybrid 4x4 200 but due to its expensive initial purchase price not many are expected to be sold. Emissions are rated at 103g/km while diesel consumption is claimed to be 72.4mpg.

At the time of the launch of the revitalised model the lowest DS 5 emissions figures were for the Hybrid4x4 models, producing 103g/km. Of the conventional diesel engines, the BlueHDi 120 faired best at just 104g/km, while the sole petrol motor, the THP 165 was the most polluting at 136g/km.

By getting largely on top of previous mechanical and electrical issues years ago, DS 5 reliability shouldn’t prove to be anything less than very good.

Certainly in its previous guise as a Citroen, there were no significant maladies reported, with the DS 5’s impressive build quality and high grade materials assuring it was free from annoying squeaks and rattles, let alone anything more troubling.

Although the engines are new to the DS 5, they’ve seen reliable service in other Citroens and Peugeots, while the diesel-electric Hybrid 4x4’s underpinnings has also proved to be robust and trouble-free.

Arguably the key challenge for DS over the coming years is delivering the kind of service buyers of premium brands expect should anything untoward happen with a 5. Citroen dealers have not always been renowned for their exemplary customer service, so this will need to be consistently redressed, particularly when separate DS showroom buildings open over the next few years.
