AION V vs Kia EV4

The AION V costs £1,705 more than the Kia EV4. For that premium it adds 47 miles more WLTP range and 53 kW faster peak rapid charging. On EVcarsguide's combined category scores, the Kia EV4 comes out ahead overall.

The Kia EV4 is £1,705 cheaper to buy. Running costs are almost identical - about £144 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Kia EV4 comes out roughly £1,785 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 264 miles for the AION V and 226 miles for the Kia EV4 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The AION V goes roughly 39 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 25-31 minutes.

The two are within 6 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 546 mm of total clearance for the AION V and about 540 mm of total clearance for the Kia EV4.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 90% battery health for the AION V and 89% for the Kia EV4. That is close enough that capacity loss should not decide between them. The AION V's LFP-type pack tolerates daily 100% charging, while the Kia EV4's NMC-type pack lasts longest kept to about 80% for everyday use.
