What owners say
Aggregated from UK owner forums and communities - the things you only learn after living with the car.
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.
BMW iX
xDrive60 M Sport
Owners love
- Strong performance across the range, with M60 variant achieving 3.6-second 0-60 acceleration and newer models offering up to 435-mile range
- Luxurious, comfortable driving experience with excellent refinement, quality interior design, and air suspension option
- Comprehensive standard specifications including adaptive cruise control, 360 camera, and advanced driving assistants that work intuitively
Watch out for
- Controversial and polarising front grille design that remains a significant barrier to appeal despite updates
- Limited boot space for the vehicle's overall size
- Non-air suspension models ride very firm on UK roads; air suspension is effectively essential for comfort
Owner tips
- Prioritize air suspension and rear-wheel steering as must-have options for driving comfort, handling, and parking ease
- Consider the iX60 or iX50 over smaller battery variants if doing significant mileage—better value proposition with improved efficiency and range

Frequently asked questions
Is the BMW i7 worth the extra £32,140 over the BMW iX?
The BMW i7 costs £32,140 more than the BMW iX. On the headline specs that premium buys little measurable advantage - the two are closely matched on range, charging and space. The BMW iX is not just cheaper - it also offers 39 miles more WLTP range. On EVcarsguide's combined category scores, the BMW iX comes out ahead overall.
Which is cheaper to own over 5 years, the BMW i7 or the BMW iX?
The BMW iX is £32,140 cheaper to buy. The BMW iX is cheaper to charge, roughly £152 a year versus £184 for the BMW i7, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the BMW iX comes out roughly £32,300 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 BMW iX like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 323 miles for the BMW i7 and 355 miles for the BMW iX - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The BMW iX goes roughly 32 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 34-35 minutes.
Which is easier to park and drive in town, the BMW i7 or the BMW iX?
The two are within 20 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 450 mm of total clearance for the BMW i7 and about 430 mm of total clearance for the BMW iX.
Which battery will hold up better as a used buy, the BMW i7 or the BMW iX?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the BMW i7 and 84% for the BMW iX. 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 8-year manufacturer warranty.
