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.
Mercedes-Benz EQA
250
Owners love
- Owners consistently praise the build quality, quietness and comfort, with very comfortable front seats.
- Real-world range is close to or above the official figure in summer for many owners, with around 3.5 to 4.5 miles per kWh reported.
- Rapid charging holds a high rate for much of the charge, so stops are quick by the standards of its size.
Watch out for
- The car has no built-in charge scheduling, so owners rely on a smart home charger or tariff app for cheap night rates.
- Winter range drops to roughly 200 miles or less, and the range display can be inaccurate.
- The boot is small and rear legroom is tight for tall passengers because of the raised floor.
Owner tips
- Use a smart home charger or tariff app to time charging, as the car cannot.
- Use the D Auto regeneration setting for the best efficiency.

EVcarsguide estimates a real-world motorway range of about 184 miles for the Audi Q4 e-tron and 219 miles for the Mercedes-Benz EQA - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Mercedes-Benz EQA goes roughly 35 miles further between charging stops.
Which is easier to park and drive in town, the Audi Q4 e-tron or the Mercedes-Benz EQA?
The Mercedes-Benz EQA is the easier car for tight UK car parks: it is 31 mm narrower than the Audi Q4 e-tron. In a standard 2,400 mm bay that leaves about 566 mm of total clearance for the Mercedes-Benz EQA and about 535 mm of total clearance for the Audi Q4 e-tron. The Audi Q4 e-tron also turns in a 1.2 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 Mercedes-Benz EQA?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Audi Q4 e-tron and 84% for the Mercedes-Benz EQA. 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.
