Audi e-tron vs MG S6 EV

The Audi e-tron costs £21,905 more than the MG S6 EV. For that premium it adds 50 kW more power and a 2.4s quicker 0-62mph time. The MG S6 EV is not just cheaper - it also offers 120 miles more WLTP range and 30 kW faster peak rapid charging. On EVcarsguide's combined category scores, the MG S6 EV comes out ahead overall.

The MG S6 EV is £21,905 cheaper to buy. The MG S6 EV is cheaper to charge, roughly £184 a year versus £232 for the Audi 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 £22,145 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 174 miles for the Audi e-tron 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 MG S6 EV goes roughly 58 miles further between charging stops. A rapid charge to 80% takes around 30 minutes in the Audi e-tron and 38 in the MG S6 EV, so the Audi e-tron loses less time at each stop. So the MG S6 EV stops less often while the Audi e-tron stops for less time - pick on which you would rather do.

The two are within 23 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 465 mm of total clearance for the Audi 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 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.
