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 231 miles for the Audi e-tron Sportback 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 e-tron Sportback goes roughly 39 miles further between charging stops.

So the Audi e-tron Sportback stops less often while the XPENG G6 stops for less time - pick on which you would rather do.
The two are within 15 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 465 mm of total clearance for the Audi e-tron Sportback. 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 e-tron Sportback 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 e-tron Sportback's NMC-type pack lasts longest kept to about 80% for everyday use. Both batteries carry a 8-year manufacturer warranty.
