Hyundai has lowered the official driving range for the Hyundai Kona Electric due to WLTP’s erroneous data. The same happened with the sibling Kia e-Niro before.
The carmaker revealed that an external test agency broke test procedures and got false results. Previously, the range of the Kia e-Niro was also downgraded for the same reason (incorrect testing methodology for WLTP).
After recalculations the 39kWh Kona Electric’s range has been down from 186 to 180 miles (from 299 to 290 km).
The range of the high-level model with a more powerful 64kWh battery has been reduced from 292 to 279 miles (from 470 to 449 km).
As for the Niro EV, the 39kWh version has 179 miles (288 km) instead of previous 193 miles (310 km). The 64kWh model is downgraded from 282 (454 km) to 201 miles (324 km).
According to Hyundai, during the test a disproportionate length of time on the WLTP ‘urban’ cycle (inclusive lower overall car speeds and a reduced energy need) resulted in an overestimation of the Kona’s electric range.
The company is investigating the situation to find a complete understanding.
