MG S6 EV
The Audi Q8 e-tron costs £29,805 more than the MG S6 EV. For that premium it adds 70 kW more power and a 3.6s quicker 0-62mph time. The MG S6 EV is not just cheaper - it also offers 48 miles more WLTP range and 105 litres more boot space. On EVcarsguide's combined category scores, the MG S6 EV comes out ahead overall.
The MG S6 EV is £29,805 cheaper to buy. The MG S6 EV is cheaper to charge, roughly £184 a year versus £232 for the Audi Q8 e-tron, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the MG S6 EV comes out roughly £30,045 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 234 miles for the Audi Q8 e-tron and 232 miles for the MG S6 EV - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV. Both rapid-charge to 80% in a similar time, around 31-38 minutes.
The two are within 25 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 488 mm of total clearance for the MG S6 EV and about 463 mm of total clearance for the Audi Q8 e-tron. The MG S6 EV also turns in a 1.1 m tighter circle, which helps with U-turns and multi-storey ramps.
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Audi Q8 e-tron 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. Both batteries carry a 8-year manufacturer warranty.
