Add 5 years of charging and the XPENG G6 comes out roughly £28,010 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 193 miles for the XPENG G6 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Audi Q8 e-tron goes roughly 42 miles further between charging stops. A rapid charge to 80% takes around 31 minutes in the Audi Q8 e-tron and 12 in the XPENG G6, so the XPENG G6 loses less time at each stop. So the Audi Q8 e-tron stops less often while the XPENG G6 stops for less time - pick on which you would rather do.
The two are within 17 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 480 mm of total clearance for the XPENG G6 and about 463 mm of total clearance for the Audi Q8 e-tron. The XPENG G6 also turns in a 0.6 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 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 Audi Q8 e-tron's NMC-type pack lasts longest kept to about 80% for everyday use. Both batteries carry a 8-year manufacturer warranty.
