Hyundai KONA Electric
The Hyundai KONA Electric costs £12,755 more than the Hyundai Ioniq 3. For that premium it adds 106 miles more WLTP range, 52 kW more power and a 1.0s quicker 0-62mph time. On EVcarsguide's combined category scores, the Hyundai Ioniq 3 comes out ahead overall.
The Hyundai Ioniq 3 is £12,755 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 £12,755 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 178 miles for the Hyundai Ioniq 3 and 266 miles for the Hyundai KONA Electric - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Hyundai KONA Electric goes roughly 88 miles further between charging stops. A rapid charge to 80% takes around 29 minutes in the Hyundai Ioniq 3 and 41 in the Hyundai KONA Electric, so the Hyundai Ioniq 3 loses less time at each stop. So the Hyundai KONA Electric stops less often while the Hyundai Ioniq 3 stops for less time - pick on which you would rather do.
The two are within 25 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 575 mm of total clearance for the Hyundai KONA Electric.
