Cadillac OPTIQ vs Subaru Solterra

EVcarsguide estimates a real-world motorway range of about 220 miles for the Cadillac OPTIQ and 241 miles for the Subaru Solterra - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Subaru Solterra goes roughly 21 miles further between charging stops. A rapid charge to 80% takes around 30 minutes in the Cadillac OPTIQ and 20 in the Subaru Solterra, so the Subaru Solterra loses less time at each stop. That makes the Subaru Solterra the stronger long-distance car.

The Subaru Solterra is the easier car for tight UK car parks: it is 52 mm narrower than the Cadillac OPTIQ. In a standard 2,400 mm bay that leaves about 540 mm of total clearance for the Subaru Solterra and about 488 mm of total clearance for the Cadillac OPTIQ.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 89% battery health for the Cadillac OPTIQ and 84% for the Subaru Solterra. That gives the Cadillac OPTIQ a modest edge in retained real-world range. Both use NMC-type cells, so for daily use keep the charge limit near 80% to slow degradation.
