How much is it going to cost to run?

The DS 7 Crossback has similar running costs to its Peugeot 3008 cousin, even though it’s pitched in a much higher area of the market. Claimed fuel economy varies from around 48mpg to just over 68mpg – reasonably strong figures for the class of car, meaning low fuel bills.

MPG and CO2

The E-Tense achieves 128.4mpg and 33g/km CO2 on the new WLTP test cycle, though you’ll need to keep the battery charged to achieve anything close to those figures – a full battery charge takes two hours from a 6.6kW charger, or eight hours using a three-pin domestic socket.

It’s likely that the DS 7 E-Tense can both greatly improve on it’s already impressive economy figures and fall depressingly short. Do shorter trips and religiously keep the battery charged and there’s little need to burn any fuel at all – the DS can cover up to 31 miles on pure electric power, and achieve speeds of up to 83mph silently too.

The BlueHDi 130 returns a claimed 68mpg, while the 180hp version is capable of 57mpg according to DS. The 1.5-litre BlueHDi diesel emits less than 110g/km of CO2 emissions, making it the cleanest engine in the DS 7 Crossback range.

The petrol isn’t bad, either, with a CO2 emissions figure of 134g/km for a 25% BIK band – an impressive effort considering the size of the DS 7 Crossback.

Reliability

Parent company PSA has a patchy reliability record
The breakdown and warranty figures don’t justify this
Solidity and quality feel good, if not quite up with Audi

Peugeot and Citroen still has a poor reputation for reliability with car buyers, which is unjustified these days. Tech like the LED instrumentation and adaptive cruise control may have some teething troubles, but DS dealers should iron out these problems early on. The firm says that the dealer experience for these cars is much better than it was in the past.

DS Automobiles has produced a quality feel for its interior, with extensive use of luxurious materials, to provide a premium experience. Whether that will result in Audi-levels of longevity remains to be seen – although we’re hearing no horror stories from owners right now.
