The MG S6 EV is not just cheaper - it also offers 58 miles more WLTP range and 103 litres more boot space. On EVcarsguide's combined category scores, the MG S6 EV comes out ahead overall.

The MG S6 EV is £1,995 cheaper to buy. Running costs are almost identical - about £184 a year either way, at 8,000 miles on an off-peak home tariff.

EVcarsguide estimates a real-world motorway range of about 232 miles for the MG S6 EV and 193 miles for the XPENG G6 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The MG S6 EV goes roughly 39 miles further between charging stops. A rapid charge to 80% takes around 38 minutes in the MG S6 EV and 12 in the XPENG G6, so the XPENG G6 loses less time at each stop. So the MG S6 EV stops less often while the XPENG G6 stops for less time - pick on which you would rather do.

The two are within 8 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 480 mm of total clearance for the XPENG G6. The MG S6 EV also turns in a 0.5 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 MG S6 EV and 90% for the XPENG G6. That gives the XPENG G6 a modest edge in retained real-world range. The XPENG G6's LFP-type pack tolerates daily 100% charging, while the MG S6 EV's NMC-type pack lasts longest kept to about 80% for everyday use. Both batteries carry a 8-year manufacturer warranty.
