EVcarsguide estimates a real-world motorway range of about 229 miles for the Audi Q4 e-tron and 241 miles for the Subaru Solterra - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV.
Which is easier to park and drive in town, the Audi Q4 e-tron or the Subaru Solterra?
The two are within 5 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 540 mm of total clearance for the Subaru Solterra and about 535 mm of total clearance for the Audi Q4 e-tron. The Audi Q4 e-tron also turns in a 1.0 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 Q4 e-tron and 84% for the Subaru Solterra. 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.
