MPG, running costs & CO2 Rating

4.0 out of 5

The DS 7 is a luxury SUV, but its underpinnings and diesel engines have all been honed to serve up excellent fuel economy and low emissions. On the whole, they do this successfully, but the plug-in hybrid version will be particularly desirable for company-car drivers.

As far as running costs go, the E-Tense plug-in hybrid is the star of the show, thanks to its all-electric range of up to 40 miles. Not only is it more economical, but with a 197bhp petrol engine and two 107bhp electric motors it’s faster too. A front-wheel drive Hybrid with less power is likely to be the pick of the range.

DS 7 Crossback MPG & CO2

Choose a diesel and there’s the option of a 1.5-litre with 128bhp or a larger 2.0-litre engine with 178bhp. The former is the most economical, returning an impressive 55.3mpg, while the more powerful version promises up to 48.2mpg. The latter puts the front-wheel-drive DS 7 just ahead of the equivalent Audi Q3 2.0-litre TDI quattro, which can hit 40.4mpg. CO2 emissions from 137g/km are also just ahead of the Audi’s best figure and put the 2.0-litre BlueHDi DS 7 in a middling Benefit-in-Kind (BiK) band for company-car tax.

The PureTech 225 petrol engine is a turbocharged 1.6-litre, mated to an eight-speed automatic gearbox as standard and with claimed fuel economy of up to 40.4mpg. CO2 emissions of 164g/km result in a high BiK band. The 1.2-litre PureTech 130 engine is more economical, returning up to 46mpg with CO2 emissions from 143g/km.

For truly low emissions figures, only the plug-in hybrid E-Tense versions will suffice. Thanks to a 13.2kWh battery pack, the DS 7 E-Tense can travel for up to 40 miles without using its petrol engine, resulting in official numbers of up to 235mpg and CO2 emissions from 30-39g/km. This lowers BiK liability substantially and will also allow owners to enter low emissions zones such as Central London for free.

As with any plug-in hybrid, it's worth noting the fuel-efficiency figure will largely depend upon how often you charge the battery and how far you drive. A full charge from a 7kW home wallbox takes under two hours, while using a three-pin plug takes eight.

Insurance groups

Insurance groups for the BlueHDi 130 engine range from 21 to 23, depending on trim level. Meanwhile, the BlueHDi 180 and PureTech 225 engines both sit in the same groups from 29 to 31. The Audi Q3 sits in insurance groups from 20 to 28, while the BMW X1 resides in groups 24 to 34.


The DS 7 comes with a three-year/60,000-mile warranty, which matches Audi's, but looks a bit stingy. Rival BMW offers three years/100,000 miles, the same cover as the Renault Koleos.


Servicing plans will be available for customers who'd prefer to pay a monthly fee for a set period, or up front. The former is likely to be of particular appeal, as it allows owners to spread the cost of maintenance and avoid surprise bills.
