DS 3 Crossback review - MPG, CO2 and Running Costs

Good economy and cheaper running costs than many rivals are two of the DS 3 Crossback’s redeeming features. The most frugal model is the BlueHDi 100, with official fuel economy figures of 54.4mpg to 62.7mpg depending on spec.

Of the three petrol options it’s the least powerful that’s easiest on fuel: the PureTech 100 manages 46mpg to 52mpg, while the 130 returns 42.2 to 47.1mpg. The most powerful PureTech 155 model is (predictably) the least efficient, with official figures of between 41.7mpg and 46.6mpg.

It’s a similar story with CO2 emissions too. They sit at 97-102g/km for the diesel, 105-113g/km for the PureTech 100, 109-117g/km for the PureTech 130 and 114-121g/km for the top-spec PureTech 155. All these figures are subject to varying wheel sizes and weight changes depending on which trim level you choose – stay with smaller wheels if economy and efficiency is a primary concern.

All internal-combustion-powered DS 3 Crossback models will cost £145 per year to tax, after the initial CO2-weighted first year payment that’s usually rolled into the on-the-road price. You can go as mad as you like with options and personalisation without fear of hitting the £40,000-plus surcharge, however. Prices top out just shy of £36,000 for a kitted-out La Premiere model.

Insurance groups

The DS 3 Crossback occupies insurance groups 14 to 24; the lower end of that spectrum accounts for PureTech 100 models, with premiums increasing with engine power and pricier trims. For comparison, the Audi Q2 begins one group below and tops out (sporty SQ2 notwithstanding) in group 27 for a 40 TFSI petrol model. 

Depreciation

Despite its left-field appeal, the DS 3 Crossback is likely to hold on to around 40 to 49 per cent of its value after three years and 36,000 miles come trade-in time, according to our experts. This compares favorably with rivals like the Lexus UX (46 to 53 per cent) and Mazda CX-3 (43 to 51 per cent).
