Mercedes-Benz EQS
Mercedes-Benz EQV
EVcarsguide estimates a real-world motorway range of about 392 miles for the Mercedes-Benz EQS and 185 miles for the Mercedes-Benz EQV - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Mercedes-Benz EQS goes roughly 207 miles further between charging stops.
The two are within 2 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 474 mm of total clearance for the Mercedes-Benz EQS and about 472 mm of total clearance for the Mercedes-Benz EQV. The Mercedes-Benz EQS also turns in a 0.9 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 Mercedes-Benz EQS and 84% for the Mercedes-Benz EQV. 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.
