EVcarsguide estimates a real-world motorway range of about 325 miles for the Audi Q6 Sportback e-tron and 196 miles for the BMW iX3 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Audi Q6 Sportback e-tron goes roughly 129 miles further between charging stops. A rapid charge to 80% takes around 22 minutes in the Audi Q6 Sportback e-tron and 34 in the BMW iX3, so the Audi Q6 Sportback e-tron loses less time at each stop. That makes the Audi Q6 Sportback e-tron the stronger long-distance car.
The BMW iX3 is the easier car for tight UK car parks: it is 48 mm narrower than the Audi Q6 Sportback e-tron. In a standard 2,400 mm bay that leaves about 509 mm of total clearance for the BMW iX3 and about 461 mm of total clearance for the Audi Q6 Sportback e-tron.
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Audi Q6 Sportback e-tron and 84% for the BMW iX3. 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.
