Kia EV6 vs Nissan ARIYA

The Kia EV6 costs £8,635 more than the Nissan ARIYA. For that premium it adds 111 miles more WLTP range and 128 kW faster peak rapid charging. On EVcarsguide's combined category scores, the Kia EV6 comes out ahead overall.

The Nissan ARIYA is £8,635 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 Nissan ARIYA comes out roughly £8,595 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 301 miles for the Kia EV6 and 209 miles for the Nissan ARIYA - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Kia EV6 goes roughly 92 miles further between charging stops. A rapid charge to 80% takes around 18 minutes in the Kia EV6 and 30 in the Nissan ARIYA, so the Kia EV6 loses less time at each stop. That makes the Kia EV6 the stronger long-distance car.

The Nissan ARIYA is the easier car for tight UK car parks: it is 40 mm narrower than the Kia EV6. In a standard 2,400 mm bay that leaves about 550 mm of total clearance for the Nissan ARIYA and about 510 mm of total clearance for the Kia EV6.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 89% battery health for the Kia EV6 and 84% for the Nissan ARIYA. 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.
