The Polestar 3 also turns in a 0.4 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 Q8 e-tron and 84% for the Polestar 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.
