Hyundai Motor is issuing a correction to the official Worldwide Harmonised Light Vehicle Test Procedure (WLTP) combined all-electric driving range (AER) stated for the Kona Electric.
All new cars to be sold in the European Union are subject to the new WLTP tests, which use a standardised test programme set and overseen by designated testing authorities.
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.
The Kona Electric in 39kWh specification is due to be recalculated with an AER combined range of 289 kilometers (180 miles). The AER of Kona Electric 64kWh is due to be recalculated with a range of 449 kilometers (279 miles).
The news comes after the electric range was also downgraded for its corporate cuisine, the Kia e-Niro.
The inconsistency in the test cycles has been identified due to Hyundai’s ongoing homologation work, and this situation is being followed closely to arrive at a full explanation.
Hyundai is concerned to have learned that the officially recognised driving range of Kona Electric must be corrected and is taking this matter seriously. No other Hyundai vehicles are affected by this issue.
