DS N°8 vs MG S6 EV

The DS N°8 costs £12,795 more than the MG S6 EV. For that premium it adds a 1.5s quicker 0-62mph time. The MG S6 EV is not just cheaper - it also offers 114 litres more boot space. On EVcarsguide's combined category scores, the DS N°8 comes out ahead overall.

The MG S6 EV is £12,795 cheaper to buy. The DS N°8 is cheaper to charge, roughly £144 a year versus £184 for the MG S6 EV, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the MG S6 EV comes out roughly £12,595 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 232 miles for the MG S6 EV - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The DS N°8 goes roughly 53 miles further between charging stops. A rapid charge to 80% takes around 27 minutes in the DS N°8 and 38 in the MG S6 EV, so the DS N°8 loses less time at each stop. That makes the DS N°8 the stronger long-distance car.

The two are within 7 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 495 mm of total clearance for the DS N°8 and about 488 mm of total clearance for the MG S6 EV.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the DS N°8 and 84% for the MG S6 EV. 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.
