The Kia EV6 costs £4,885 more than the Audi Q4 e-tron. For that premium it adds 140 miles more WLTP range, 158 kW faster peak rapid charging and 43 kW more power. On EVcarsguide's combined category scores, the Kia EV6 comes out ahead overall.
The Audi Q4 e-tron is £4,885 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 Audi Q4 e-tron comes out roughly £4,845 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 184 miles for the Audi Q4 e-tron and 301 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 117 miles further between charging stops.
The two are within 25 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 510 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.
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.
