What owners say
Aggregated from UK owner forums and communities - the things you only learn after living with the car.
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.
Ford Mustang Mach-E
Standard Range RWD (2021-24)
Owners love
- Owners consistently praise the looks, the strong acceleration and a refined, quiet drive.
- Extended Range owners report around 290 to 315 miles in mild conditions, enough to charge only every week or two for many.
- Running costs on an off-peak home tariff are very low, and owners describe large monthly savings over a petrol car.
Watch out for
- Rapid charging slows sharply above 80%, so owners plan long trips around charging to about 80%.
- Some owners find the ride fidgety on poor roads and parts of the interior plastics cheap.
- The boot is modest for an SUV of this size, and the glass roof has no blind.
Owner tips
- Choose the Extended Range if you do long trips: owners say the extra range matters more than all-wheel drive.
- Charge to about 80% on rapid chargers on long journeys to keep stops short.

Frequently asked questions
Which is cheaper to own over 5 years, the Audi Q4 e-tron or the Ford Mustang Mach-E?
The Ford Mustang Mach-E is £400 cheaper to buy. Running costs are almost identical - about £168 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the two land within £280 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 Ford Mustang Mach-E like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 184 miles for the Audi Q4 e-tron and 203 miles for the Ford Mustang Mach-E - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Ford Mustang Mach-E goes roughly 19 miles further between charging stops.
Which is easier to park and drive in town, the Audi Q4 e-tron or the Ford Mustang Mach-E?
The Audi Q4 e-tron is the easier car for tight UK car parks: it is 65 mm narrower than the Ford Mustang Mach-E. In a standard 2,400 mm bay that leaves about 535 mm of total clearance for the Audi Q4 e-tron and about 470 mm of total clearance for the Ford Mustang Mach-E. 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 Ford Mustang Mach-E?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Audi Q4 e-tron and 90% for the Ford Mustang Mach-E. That gives the Ford Mustang Mach-E a modest edge in retained real-world range. The Ford Mustang Mach-E's LFP-type pack tolerates daily 100% charging, while the Audi Q4 e-tron's NMC-type pack lasts longest kept to about 80% for everyday use. Both batteries carry a 8-year manufacturer warranty.
