The XPENG G6 costs £9,995 more than the MG MG4 EV. For that premium it adds 228 kW faster peak rapid charging, 183 litres more boot space and 78 kW more power. On EVcarsguide's combined category scores, the XPENG G6 comes out ahead overall.
The MG MG4 EV is £9,995 cheaper to buy. Running costs are almost identical - about £192 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the MG MG4 EV comes out roughly £9,995 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 181 miles for the MG MG4 EV and 193 miles for the XPENG G6 - 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 25 minutes in the MG MG4 EV and 12 in the XPENG G6, so the XPENG G6 loses less time at each stop.
The MG MG4 EV is the easier car for tight UK car parks: it is 84 mm narrower than the XPENG G6. In a standard 2,400 mm bay that leaves about 564 mm of total clearance for the MG MG4 EV and about 480 mm of total clearance for the XPENG G6. The MG MG4 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 90% battery health for the MG MG4 EV and 90% for the XPENG G6. That is close enough that capacity loss should not decide between them. Both use LFP-type cells, which are happy charged to 100% every day. Both batteries carry a 8-year manufacturer warranty.
