Cadillac OPTIQ vs Hyundai IONIQ 5

EVcarsguide estimates a real-world motorway range of about 220 miles for the Cadillac OPTIQ and 228 miles for the Hyundai IONIQ 5 - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV. A rapid charge to 80% takes around 30 minutes in the Cadillac OPTIQ and 18 in the Hyundai IONIQ 5, so the Hyundai IONIQ 5 loses less time at each stop.

The two are within 22 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 510 mm of total clearance for the Hyundai IONIQ 5 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 89% for the Hyundai IONIQ 5. 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.
