What owners say
Aggregated from UK owner forums and communities - the things you only learn after living with the car.
Shared watch-outs for both cars
Owners of every car here flag real-world range. Worth checking on a test drive whichever you choose.
Audi Q4 e-tron
35 e-tron
Owners love
- Owners consistently praise the quiet, refined cabin and comfortable ride.
- The interior quality and conventional layout, including physical climate controls, are rated above the VW ID.4 and Skoda Enyaq it is based on.
- Rear passenger space and headroom are generous for the size of car.
Watch out for
- Real-world range falls well short of the WLTP figure, with owners of the 40 typically seeing 230-290 miles in mild weather and around 200 in freezing conditions.
- Efficiency is middling, around 3 miles per kWh on average and much less in cold city driving.
- The myAudi app and in-car software are widely described as limited or awkward, and some cars needed software updates.
Owner tips
- Judge battery health from a full-charge range over several days, not one cold-weather reading: the display is based on recent driving.
- Check whether the car has the optional heat pump if you do a lot of winter driving.
Kia EV6
Air 77.4kWh
Owners love
- Very fast rapid charging, with owners regularly seeing 200 kW or more on ultra-rapid chargers
- Comfortable, quiet and refined on long journeys
- Distinctive design that owners still like years on
Watch out for
- Failures of the ICCU (the unit that charges the 12V battery) are the biggest theme, covered by a UK recall, sometimes with long waits for parts
- 12V battery problems, often linked to the ICCU, can leave the car unable to start
- Mixed experiences of Kia dealers, with slow parts and patchy communication
Owner tips
- Check the ICCU recall has been done and ask whether the unit was replaced
- Ask whether the 12V battery has been tested or replaced

Frequently asked questions
Which is cheaper to own over 5 years, the Audi Q4 e-tron or the Kia EV6?
The Audi Q4 e-tron is £145 cheaper to buy. Running costs are almost identical - about £160 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the two land within £105 of each other - effectively the same to own. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the Audi Q4 e-tron and Kia EV6 like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 184 miles for the Audi Q4 e-tron and 273 miles for the Kia EV6 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Kia EV6 goes roughly 89 miles further between charging stops.
Which is easier to park and drive in town, the Audi Q4 e-tron or the Kia EV6?
The two are within 15 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 535 mm of total clearance for the Audi Q4 e-tron and about 520 mm of total clearance for the Kia EV6. The Audi Q4 e-tron also turns in a 1.4 m tighter circle, which helps with U-turns and multi-storey ramps.
Which battery will hold up better as a used buy, the Audi Q4 e-tron or the Kia EV6?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Audi Q4 e-tron and 89% for the Kia EV6. That gives the Kia EV6 a modest edge in retained real-world range. Both use NMC-type cells, so for daily use keep the charge limit near 80% to slow degradation. The Audi Q4 e-tron has the longer battery warranty at 8 years, versus 7 for the Kia EV6.
