These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the Audi A6 Avant e-tron and Tesla Model S like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 364 miles for the Audi A6 Avant e-tron and 280 miles for the Tesla Model S - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Audi A6 Avant e-tron goes roughly 85 miles further between charging stops. A rapid charge to 80% takes around 21 minutes in the Audi A6 Avant e-tron and 30 in the Tesla Model S, so the Audi A6 Avant e-tron loses less time at each stop. That makes the Audi A6 Avant e-tron the stronger long-distance car.
Which is easier to park and drive in town, the Audi A6 Avant e-tron or the Tesla Model S?
The Audi A6 Avant e-tron is the easier car for tight UK car parks: it is 77 mm narrower than the Tesla Model S. In a standard 2,400 mm bay that leaves about 513 mm of total clearance for the Audi A6 Avant e-tron and about 436 mm of total clearance for the Tesla Model S. The Tesla Model S 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 Audi A6 Avant e-tron and 84% for the Tesla Model S. 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.
