Frequently asked questions

The Mercedes-Benz EQS SUV costs £50,765 more than the BMW iX. For that premium it adds 65 litres more boot space and 2 more seats (7 versus 5). The BMW iX is not just cheaper - it also offers 60 miles more WLTP range, 135 kW more power and a 1.5s quicker 0-62mph time. On EVcarsguide's combined category scores, the BMW iX comes out ahead overall.
Which is cheaper to own over 5 years, the BMW iX or the Mercedes-Benz EQS SUV?
The BMW iX is £50,765 cheaper to buy. The BMW iX is cheaper to charge, roughly £152 a year versus £224 for the Mercedes-Benz EQS SUV, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the BMW iX comes out roughly £51,125 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the BMW iX and Mercedes-Benz EQS SUV like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 355 miles for the BMW iX and 305 miles for the Mercedes-Benz EQS SUV - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The BMW iX goes roughly 50 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 32-35 minutes.
Which is easier to park and drive in town, the BMW iX or the Mercedes-Benz EQS SUV?
The two are within 11 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 441 mm of total clearance for the Mercedes-Benz EQS SUV and about 430 mm of total clearance for the BMW iX. The Mercedes-Benz EQS SUV also turns in a 0.9 m tighter circle, which helps with U-turns and multi-storey ramps.
Which battery will hold up better as a used buy, the BMW iX or the Mercedes-Benz EQS SUV?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the BMW iX and 84% for the Mercedes-Benz EQS SUV. 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 SUV has the longer battery warranty at 10 years, versus 8 for the BMW iX.
