The long-range Hyundai Kona EV has had its range downgraded on the WLTP test cycle, after the company discovered its external test agency hadn't followed the correct test procedure.
Kia last week downgraded the range of its e-Niro for the same reason. The re-rating means the 39kWh Kona is rated for 289km instead of 300km, while the 64kWh model is officially good for 449km rather than the 470km initially promised.
