Frequently asked questions
What are the Audi A6 Avant e-tron and Tesla Model 3 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 312 miles for the Tesla Model 3 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Audi A6 Avant e-tron goes roughly 52 miles further between charging stops.
Which is easier to park and drive in town, the Audi A6 Avant e-tron or the Tesla Model 3?
The Tesla Model 3 is the easier car for tight UK car parks: it is 37 mm narrower than the Audi A6 Avant e-tron. In a standard 2,400 mm bay that leaves about 550 mm of total clearance for the Tesla Model 3 and about 513 mm of total clearance for the Audi A6 Avant e-tron. The Tesla Model 3 also turns in a 0.7 m tighter circle, which helps with U-turns and multi-storey ramps.
Which battery will hold up better as a used buy, the Audi A6 Avant e-tron or the Tesla Model 3?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Audi A6 Avant e-tron and 85% for the Tesla Model 3. 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.
