Kia EV9 vs Volvo EX90 (2024-2025)

The Volvo EX90 costs £29,610 more than the Kia EV9. For that premium it adds 25 miles more WLTP range, 40 kW faster peak rapid charging and 150 kW more power. On EVcarsguide's combined category scores, the Volvo EX90 comes out ahead overall.

The Kia EV9 is £29,610 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 Kia EV9 comes out roughly £29,650 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 291 miles for the Kia EV9 and 312 miles for the Volvo EX90 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Volvo EX90 goes roughly 21 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 22-24 minutes.

The two are within 16 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 436 mm of total clearance for the Volvo EX90 and about 420 mm of total clearance for the Kia EV9. The Volvo EX90 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 Kia EV9 and 84% for the Volvo EX90. That gives the Kia EV9 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. The Volvo EX90 has the longer battery warranty at 8 years, versus 7 for the Kia EV9.
