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 (PHEV) is the star of the show. Not only is it more economical but it’s faster too. A front-wheel drive hybrid with a combined 222bhp from its petrol engine and electric motor would be our pick of the range, thanks to the claimed economy figure of 176.6mpg. The 297bhp version gets an extra electric motor on the rear axle and offers up to 188mpg.

Thanks to a 13.2kWh battery, the DS 7 E-Tense can travel for up to 36 miles without using its petrol engine, resulting in official CO2 emissions from 35-39g/km. This lowers BiK liability substantially, with rates starting from 11% for the plug-in hybrid models. The E-Tense 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.

DS 7 Crossback MPG & CO2

For diesel fans there’s the option of a 1.5-litre engine with 128bhp. The larger 2.0-litre engine with 178bhp has been discontinued. The former is the most economical of the two, returning an impressive 55.3mpg, while the 2.0-litre engine promises up to 48.2mpg. CO2 emissions from 140g/km put the 1.5-litre BlueHDi DS 7 in a high Benefit-in-Kind band for company-car tax of 32%.

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 39.8mpg. CO2 emissions from 164g/km result in a higher BiK band. The 1.2-litre PureTech 130 engine is more economical, returning up to 43.5mpg with CO2 emissions from 147g/km.

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.

Warranty

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

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.
