Which is easier to park and drive in town, the Audi Q8 e-tron or the BMW iX3?
The BMW iX3 is the easier car for tight UK car parks: it is 46 mm narrower than the Audi Q8 e-tron. In a standard 2,400 mm bay that leaves about 509 mm of total clearance for the BMW iX3 and about 463 mm of total clearance for the Audi Q8 e-tron.

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 BMW iX3.
