Mercedes-Benz EQS vs Volvo ES90

The Mercedes-Benz EQS costs £24,205 more than the Volvo ES90. For that premium it adds 81 miles more WLTP range, 186 litres more boot space and a 2.3s quicker 0-62mph time. On EVcarsguide's combined category scores, the Mercedes-Benz EQS comes out ahead overall.

EVcarsguide estimates a real-world motorway range of about 392 miles for the Mercedes-Benz EQS and 286 miles for the Volvo ES90 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Mercedes-Benz EQS goes roughly 106 miles further between charging stops. A rapid charge to 80% takes around 31 minutes in the Mercedes-Benz EQS and 22 in the Volvo ES90, so the Volvo ES90 loses less time at each stop. So the Mercedes-Benz EQS stops less often while the Volvo ES90 stops for less time - pick on which you would rather do.

The two are within 16 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 458 mm of total clearance for the Volvo ES90. The Mercedes-Benz EQS also turns in a 1.1 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 Volvo ES90. 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.
