Mercedes-Benz EQS
The Mercedes-Benz EQS costs £8,230 more than the Mercedes-Benz EQS. On the headline specs that premium buys little measurable advantage - the two are closely matched on range, charging and space. The Mercedes-Benz EQS is not just cheaper - it also offers 37 miles more WLTP range and a 1.9s 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 378 miles for the Mercedes-Benz EQS - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV. Both rapid-charge to 80% in a similar time, around 31-31 minutes.
The two are within 0 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 474 mm of total clearance for the Mercedes-Benz EQS.
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 EQS. 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. Both batteries carry a 10-year manufacturer warranty.
