Polestar 2
EVcarsguide estimates a real-world motorway range of about 288 miles for the Alpine A390 and 253 miles for the Polestar 2 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Alpine A390 goes roughly 35 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 25-28 minutes.
The two are within 26 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 541 mm of total clearance for the Polestar 2 and about 515 mm of total clearance for the Alpine A390. The Alpine A390 also turns in a 0.5 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 Alpine A390 and 84% for the Polestar 2. 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.
