These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the Audi Q8 e-tron and Tesla Model X like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 234 miles for the Audi Q8 e-tron and 171 miles for the Tesla Model X - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Audi Q8 e-tron goes roughly 63 miles further between charging stops. A rapid charge to 80% takes around 31 minutes in the Audi Q8 e-tron and 40 in the Tesla Model X, so the Audi Q8 e-tron loses less time at each stop. That makes the Audi Q8 e-tron the stronger long-distance car.
Which is easier to park and drive in town, the Audi Q8 e-tron or the Tesla Model X?
The Audi Q8 e-tron is the easier car for tight UK car parks: it is 62 mm narrower than the Tesla Model X. In a standard 2,400 mm bay that leaves about 463 mm of total clearance for the Audi Q8 e-tron and about 401 mm of total clearance for the Tesla Model X.
Which battery will hold up better as a used buy, the Audi Q8 e-tron or the Tesla Model X?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Audi Q8 e-tron and 84% for the Tesla Model X. 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.
