What owners say

Shared watch-outs for both cars
Owners of every car here flag infotainment & software. Worth checking on a test drive whichever you choose.
BMW i7
xDrive60
Owners love
- Exceptionally smooth, quiet and comfortable, with standout rear-seat luxury.
- Air suspension and rear-wheel steering make it feel smaller than it is, with a good turning circle.
- Owners report over 300 miles of real range, so charging stops are rare on long trips.
Watch out for
- At about 5.4 metres long it is hard to park in UK spaces and multi-storey car parks.
- The styling divides opinion sharply.
- Rapid charging, at up to 195 kW, is slower than some rivals.
Owner tips
- Measure your garage and regular parking spaces before you buy.
- Check which options the car has: equipment varies widely and decides much of the price.
Mercedes-Benz EQS
450+
Owners love
- Owners report 400 to 450 miles in mild weather and a range estimate they can trust.
- The powertrain is almost silent, even at motorway speeds.
- Rear-wheel steering gives it a turning circle far tighter than its size suggests.
Watch out for
- The menus are deep and confusing, and face recognition and voice control often fail.
- Cabin quality disappoints at the price: air vents, door cards and the dashboard feel flimsy.
- 200 kW peak charging is slower than rivals; 10-80% takes about 31 minutes.
Owner tips
- Ask for a battery health report before buying, and how the car was charged.
- Check what the battery warranty covers for that car: owners say Mercedes changed its terms in 2024.

Frequently asked questions
Is the BMW i7 worth the extra £10,550 over the Mercedes-Benz EQS?
The BMW i7 costs £10,550 more than the Mercedes-Benz EQS. For that premium it adds 155 kW more power and a 1.5s quicker 0-62mph time. The Mercedes-Benz EQS is not just cheaper - it also offers 65 miles more WLTP range and 110 litres more boot space. On EVcarsguide's combined category scores, the Mercedes-Benz EQS comes out ahead overall.
Which is cheaper to own over 5 years, the BMW i7 or the Mercedes-Benz EQS?
The Mercedes-Benz EQS is £10,550 cheaper to buy. Running costs are almost identical - about £176 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Mercedes-Benz EQS comes out roughly £10,590 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 i7 and Mercedes-Benz EQS like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 323 miles for the BMW i7 and 378 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 55 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 31-34 minutes.
Which is easier to park and drive in town, the BMW i7 or the Mercedes-Benz EQS?
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.
Which battery will hold up better as a used buy, the BMW i7 or the Mercedes-Benz EQS?
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.
