What owners say
Aggregated from UK owner forums and communities - the things you only learn after living with the car.
Audi Q6 Sportback e-tron
quattro
Owners love
- Owners describe the handling as sharp and agile, feeling smaller to drive than its size suggests.
- Standard equipment is generous even on the Sport, with adaptive cruise, lane keeping, keyless entry and heated seats and steering wheel.
- The deep boot and large front storage area are praised as practical.
Watch out for
- The ride on sports suspension and larger wheels, notably the Edition 1 on 21-inch wheels, is widely described as too firm for the price.
- Several owners find road and wind noise more noticeable than in the older e-tron and Q8 e-tron.
- Early cars had software faults: a digital key that needed a dealer update, missing Wi-Fi connection and infotainment errors.
Owner tips
- Test drive the exact wheel and suspension combination you are considering, as the ride varies a lot across versions.
- A Sport or S line on smaller wheels is the comfort pick according to owners.
BMW iX
xDrive40
Owners love
- Owners praise the comfort and refinement, especially with air suspension, and the roomy cabin.
- Long-term owners report few faults and little battery wear, with one reporting 3% after two and a half years.
- The xDrive50 is reported to meet or beat its official range in summer, and rapid charging is fast and dependable.
Watch out for
- The xDrive40's smaller battery is the main complaint: owners report about 170 to 230 miles in real use, less in winter.
- Several owners report insurers declining to renew iX policies or quoting much higher premiums.
- Owners report fast tyre wear on some cars, and the turning circle is large without rear-wheel steering.
Owner tips
- Choose an xDrive50 if you drive long distances: it has far more range than the xDrive40.
- Get insurance quotes, including from specialist brokers, before you buy.

Frequently asked questions
Is the Audi Q6 Sportback e-tron worth the extra £1,570 over the BMW iX?
The Audi Q6 Sportback e-tron costs £1,570 more than the BMW iX. For that premium it adds 133 miles more WLTP range, 120 kW faster peak rapid charging and 45 kW more power. The BMW iX is not just cheaper - it also offers a 1.3s quicker 0-62mph time. On EVcarsguide's combined category scores, the Audi Q6 Sportback e-tron comes out ahead overall.
Which is cheaper to own over 5 years, the Audi Q6 Sportback e-tron or the BMW iX?
The BMW iX is £1,570 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 BMW iX comes out roughly £1,450 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the Audi Q6 Sportback e-tron and BMW iX like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 325 miles for the Audi Q6 Sportback e-tron and 214 miles for the BMW iX - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Audi Q6 Sportback e-tron goes roughly 111 miles further between charging stops. A rapid charge to 80% takes around 22 minutes in the Audi Q6 Sportback e-tron and 35 in the BMW iX, so the Audi Q6 Sportback e-tron loses less time at each stop. That makes the Audi Q6 Sportback e-tron the stronger long-distance car.
Which is easier to park and drive in town, the Audi Q6 Sportback e-tron or the BMW iX?
The Audi Q6 Sportback e-tron is the easier car for tight UK car parks: it is 31 mm narrower than the BMW iX. In a standard 2,400 mm bay that leaves about 461 mm of total clearance for the Audi Q6 Sportback e-tron and about 430 mm of total clearance for the BMW iX. The Audi Q6 Sportback e-tron also turns in a 0.7 m tighter circle, which helps with U-turns and multi-storey ramps.
Which battery will hold up better as a used buy, the Audi Q6 Sportback e-tron or the BMW iX?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Audi Q6 Sportback e-tron 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.
