Hyundai Motor is issuing a change to the WLTP electric driving range for the Kona. The correction is due to the testing error in the Worldwide Harmonised Light Vehicle Test Procedure (WLTP). All vehicles in the EU had to go through WLTP test. It is overseen by designated testing personnel and uses standard test programme. During testing of Hyundai Kona for all-electric driving range, the organization overseeing the test inadvertently provided an incorrect testing methodology and then approved the generated results.
It led to Hyundai Kona being tested for inconsistent length of time on urban cycle. This compromised lower overall vehicle speeds and a reduced energy requirement. All the faults gave an overestimation of all-electric driving range. Official electric driving range of Hyundai Kona is now 279 miles from 64kWh battery pack. Earlier, it was 292 miles on official WLTP cycle. Similar changes were made to the base model of Hyundai Kona which uses 39kWh battery pack. Recalculated driving range now stands at 180 miles instead of original stated 186 miles.
This testing error in Hyundai Kona was discovered through company’s ongoing homologation process. South Korean automaker further added that no other vehicles were affected because of this issue. Hyundai will investigate the issue further to arrive at full explanation. Entry-level Kona offered with 133hp from electric motors and 39kWh battery. Long range model comes with 64kWh battery and 201hp electric motor.
