BMW i7 vs Mercedes-Benz EQS

The BMW i7 costs £12,465 more than the Mercedes-Benz EQS. For that premium it adds 65 kW more power. The Mercedes-Benz EQS is not just cheaper - it also offers 39 miles more WLTP range and 110 litres more boot space. On EVcarsguide's combined category scores, the Mercedes-Benz EQS comes out ahead overall.

EVcarsguide estimates a real-world motorway range of about 362 miles for the BMW i7 and 392 miles for the Mercedes-Benz EQS - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Mercedes-Benz EQS goes roughly 30 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 31-34 minutes.

The two are within 24 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 450 mm of total clearance for the BMW i7. The Mercedes-Benz EQS also turns in a 2.2 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 BMW i7 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. The Mercedes-Benz EQS has the longer battery warranty at 10 years, versus 8 for the BMW i7.
