The MG S6 EV is not just cheaper - it also offers 52 miles more WLTP range and 59 litres more boot space. On EVcarsguide's combined category scores, the MG S6 EV comes out ahead overall.

The MG S6 EV is £41,905 cheaper to buy. The MG S6 EV is cheaper to charge, roughly £184 a year versus £232 for the Audi e-tron Sportback, at 8,000 miles on an off-peak home tariff.

EVcarsguide estimates a real-world motorway range of about 231 miles for the Audi e-tron Sportback 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. A rapid charge to 80% takes around 30 minutes in the Audi e-tron Sportback and 38 in the MG S6 EV, so the Audi e-tron Sportback loses less time at each stop.

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 Sportback. 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 Sportback 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.
