Cadillac OPTIQ vs XPENG G6

EVcarsguide estimates a real-world motorway range of about 220 miles for the Cadillac OPTIQ and 193 miles for the XPENG G6 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Cadillac OPTIQ goes roughly 27 miles further between charging stops. A rapid charge to 80% takes around 30 minutes in the Cadillac OPTIQ and 12 in the XPENG G6, so the XPENG G6 loses less time at each stop. So the Cadillac OPTIQ stops less often while the XPENG G6 stops for less time - pick on which you would rather do.

The two are within 8 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 488 mm of total clearance for the Cadillac OPTIQ and about 480 mm of total clearance for the XPENG G6.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 89% battery health for the Cadillac OPTIQ and 90% for the XPENG G6. That is close enough that capacity loss should not decide between them. The XPENG G6's LFP-type pack tolerates daily 100% charging, while the Cadillac OPTIQ's NMC-type pack lasts longest kept to about 80% for everyday use.
