Hyundai IONIQ 6 vs Kia EV6

The Hyundai IONIQ 6 costs £1,415 more than the Kia EV6. For that premium it adds 92 kW faster peak rapid charging. The Kia EV6 is not just cheaper - it also offers 89 litres more boot space. On EVcarsguide's combined category scores, the Kia EV6 comes out ahead overall.

The Kia EV6 is £1,415 cheaper to buy. Running costs are almost identical - about £152 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Kia EV6 comes out roughly £1,375 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 282 miles for the Hyundai IONIQ 6 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 19 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 18-18 minutes.

The two are within 10 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 520 mm of total clearance for the Hyundai IONIQ 6 and about 510 mm of total clearance for the Kia EV6. The Kia EV6 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 89% battery health for the Hyundai IONIQ 6 and 89% for the Kia EV6. 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.
