Hyundai and Kia have been forced to reduce the published range of its newest electric vehicles.

The South Korean car makers both issued revised driving ranges for the Kona EV and e-Niro respectively in Europe last week, having discovered discrepancies in the initial testing program conducted by a third-party organisation.

According to a statement issued by Hyundai in the UK, it said: “In testing the Kona Electric to establish its homologated electric vehicle driving range, the independent organisation overseeing the process accidentally provided an incorrect testing methodology and then approved the results it generated.

“This led to the Kona Electric being tested for a disproportionate length of time on the WLTP urban cycle – comprising lower overall vehicle speeds and a reduced energy requirement – resulting in an overestimation of the vehicle’s all-electric range.”

As a result, the maximum driving range of the Kona EV, which is due to arrive in Australian showrooms early next year, has been reduced from 470km to 449km in its most powerful iteration with a 64kW/h battery. A less-powerful 39kWh model has also been revised, with its mileage reduced from 310km to 289km.

Similarly, Kia said the range of its e-Niro variants has also been reduced with similar results.

Hyundai Australia has yet to reveal official figures for Australian models, but it is expected to match the new, revised European numbers. Kia has yet to confirm the e-Niro for local sales, but has admitted it is examining the vehicle as its first battery-powered model.
