EVcarsguide estimates a real-world motorway range of about 318 miles for the Audi Q6 e-tron and 294 miles for the Cupra Tavascan - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Audi Q6 e-tron goes roughly 24 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 22-28 minutes.

The Cupra Tavascan is the easier car for tight UK car parks: it is 78 mm narrower than the Audi Q6 e-tron. In a standard 2,400 mm bay that leaves about 539 mm of total clearance for the Cupra Tavascan and about 461 mm of total clearance for the Audi Q6 e-tron. The Cupra Tavascan also turns in a 1.2 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 Q6 e-tron and 84% for the Cupra Tavascan. 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.
