Finance costs are quite pricey

How much is it going to cost to run?

The DS 9 is powered by a trio of efficient petrol and hybrid powertrains and shares many components with Peugeot and Citroen models, making it a cheap and straightforward car to fuel and service. Claimed fuel economy figures are on a par with rivals but word of warning, it isn’t available with a diesel engine.

The regular non-hybrid PureTech gets a claimed 40.9mpg in the official fuel consumption tests, and our experience shows that it will be nearer 35mpg on a mix of A-roads, city driving and motorways, and nearer 40mpg on the motorway. It’s worth noting that this will soon go off sale.

There are two plug-in models to choose from. First up is the cheaper, slower, and more economical model, badged E-Tense 250. It claims 257mpg, and in a week’s worth of testing, we averaged 45mpg, with the battery pack regularly topped up. The 15.6kWh battery officially offers up 38 miles of electric-only range. We managed around 17 miles during our mid-winter testing – not long enough compared with rivals, such as the BMW 330e and Mercedes-Benz C 300 de.

The high performance plug-in, badged E-Tense 360 4x4, has an official 33-mile range and a fuel consumption rating of 157mpg. Once again, our testing showed this is quite far off the mark in real-world conditions. During our 92-mile jaunt we only managed 42mpg.

Servicing and maintenance

DS doesn’t offer any fixed-term servicing or maintenance plans, however you can get a selection of fixed-price repairs. Servicing and maintenance shouldn’t be as costly as its BMW, Audi and Volkswagen rivals, thanks to being so closely related to a wide range of Peugeot and Citroen models.

Reliability

It’s too soon to say, specifically
But the Peugeot model it’s based on has good reliability
Build quality is catching up fast with German rivals

The DS 9 feels very solid and well put together, and the Peugeot 508 it’s based upon is proving reliable with owners. Components used can be found in some of the brand’s most recent cars, however the Peugeot 3008 and 5008 have been the subject of a few minor recalls in the last couple of years.

The battery for the plug-in hybrids come with a stand-alone eight-year, 100,000 mile warranty.
