Audi Q8 e-tron
Mercedes-Benz EQC
The Audi Q8 e-tron costs £2,160 more than the Mercedes-Benz EQC. For that premium it adds 40 kW faster peak rapid charging and 69 litres more boot space. The Mercedes-Benz EQC is not just cheaper - it also offers 50 kW more power. On EVcarsguide's combined category scores, the Audi Q8 e-tron comes out ahead overall.
The Mercedes-Benz EQC is £2,160 cheaper to buy. Running costs are almost identical - about £208 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Mercedes-Benz EQC comes out roughly £2,280 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
EVcarsguide estimates a real-world motorway range of about 234 miles for the Audi Q8 e-tron and 216 miles for the Mercedes-Benz EQC - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Audi Q8 e-tron goes roughly 18 miles further between charging stops. A rapid charge to 80% takes around 31 minutes in the Audi Q8 e-tron and 40 in the Mercedes-Benz EQC, so the Audi Q8 e-tron loses less time at each stop. That makes the Audi Q8 e-tron the stronger long-distance car.
The Mercedes-Benz EQC is the easier car for tight UK car parks: it is 53 mm narrower than the Audi Q8 e-tron. In a standard 2,400 mm bay that leaves about 516 mm of total clearance for the Mercedes-Benz EQC and about 463 mm of total clearance for the Audi Q8 e-tron. The Mercedes-Benz EQC also turns in a 0.4 m tighter circle, which helps with U-turns and multi-storey ramps.
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Audi Q8 e-tron and 84% for the Mercedes-Benz EQC. 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.
