Frequently asked questions
Is the BMW iX3 worth the extra £8,060 over the DS N°8?
The BMW iX3 costs £8,060 more than the DS N°8. For that premium it adds 41 kW more power and a 0.9s quicker 0-62mph time. The DS N°8 is not just cheaper - it also offers 62 miles more WLTP range and 50 litres more boot space. On EVcarsguide's combined category scores, the DS N°8 comes out ahead overall.
Which is cheaper to own over 5 years, the BMW iX3 or the DS N°8?
The DS N°8 is £8,060 cheaper to buy. The DS N°8 is cheaper to charge, roughly £144 a year versus £216 for the BMW iX3, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the DS N°8 comes out roughly £8,420 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the BMW iX3 and DS N°8 like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 196 miles for the BMW iX3 and 285 miles for the DS N°8 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The DS N°8 goes roughly 88 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 27-34 minutes.
Which is easier to park and drive in town, the BMW iX3 or the DS N°8?
The two are within 14 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 509 mm of total clearance for the BMW iX3 and about 495 mm of total clearance for the DS N°8.
Which battery will hold up better as a used buy, the BMW iX3 or the DS N°8?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the BMW iX3 and 84% for the DS N°8. That is close enough that capacity loss should not decide between them. Both use NMC-type cells, so for daily use keep the charge limit near 80% to slow degradation.
