Frequently asked questions
Is the Kia EV2 worth the extra £5,750 over the Hyundai Ioniq 3?
The Kia EV2 costs £5,750 more than the Hyundai Ioniq 3. For that premium it adds 68 miles more WLTP range and 31 kW faster peak rapid charging. The Hyundai Ioniq 3 is not just cheaper - it also offers 79 litres more boot space. On EVcarsguide's combined category scores, the Hyundai Ioniq 3 comes out ahead overall.
Which is cheaper to own over 5 years, the Hyundai Ioniq 3 or the Kia EV2?
The Hyundai Ioniq 3 is £5,750 cheaper to buy. Running costs are almost identical - about £136 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Hyundai Ioniq 3 comes out roughly £5,790 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the Hyundai Ioniq 3 and Kia EV2 like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 178 miles for the Hyundai Ioniq 3 and 234 miles for the Kia EV2 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Kia EV2 goes roughly 57 miles further between charging stops.
Which is easier to park and drive in town, the Hyundai Ioniq 3 or the Kia EV2?
The two are within 0 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 600 mm of total clearance for the Hyundai Ioniq 3 and about 600 mm of total clearance for the Kia EV2. The Kia EV2 also turns in a 0.4 m tighter circle, which helps with U-turns and multi-storey ramps.
