DS N°8 vs Kia EV6

The DS N°8 costs £5,155 more than the Kia EV6. For that premium it adds 70 litres more boot space. The Kia EV6 is not just cheaper - it also offers 98 kW faster peak rapid charging. On EVcarsguide's combined category scores, the Kia EV6 comes out ahead overall.

The Kia EV6 is £5,155 cheaper to buy. Running costs are almost identical - about £144 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Kia EV6 comes out roughly £5,075 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.

EVcarsguide estimates a real-world motorway range of about 285 miles for the DS N°8 and 301 miles for the Kia EV6 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Kia EV6 goes roughly 16 miles further between charging stops. A rapid charge to 80% takes around 27 minutes in the DS N°8 and 18 in the Kia EV6, so the Kia EV6 loses less time at each stop. That makes the Kia EV6 the stronger long-distance car.

The two are within 15 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 510 mm of total clearance for the Kia EV6 and about 495 mm of total clearance for the DS N°8.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the DS N°8 and 89% for the Kia EV6. That gives the Kia EV6 a modest edge in retained real-world range. Both use NMC-type cells, so for daily use keep the charge limit near 80% to slow degradation.
