Hyundai IONIQ 6 N vs Kia EV9

The Hyundai IONIQ 6 N is £845 cheaper to buy. Running costs are almost identical - about £192 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Hyundai IONIQ 6 N comes out roughly £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 252 miles for the Hyundai IONIQ 6 N and 291 miles for the Kia EV9 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Kia EV9 goes roughly 39 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 18-24 minutes.

The Hyundai IONIQ 6 N is the easier car for tight UK car parks: it is 40 mm narrower than the Kia EV9. In a standard 2,400 mm bay that leaves about 460 mm of total clearance for the Hyundai IONIQ 6 N and about 420 mm of total clearance for the Kia EV9. The Hyundai IONIQ 6 N also turns in a 0.3 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 N and 89% for the Kia EV9. 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.
