The NAF tests are designed to determine how much the real driving range of electric vehicles differs from the claimed range in severe cold.
Although the EV2 was not included in the official final protocol due to its prototype status, Kia claims that it showed the best result among all participants. The version with a 61 kWh battery was used in the tests. Serial production of the model will begin in Slovakia in July. The expected range according to WLTP is 448 km or 413 km with 19-inch wheels.
In actual winter conditions, the EV2 covered 310.6 km, losing 102.4 km or 24.8% of the calculated range. The tests were conducted at temperatures from −8 to −31 °C.
The charging in the cold also performed well. The vehicle charged from 8% to 80% in just under 37 minutes, receiving 45.4 kWh of energy. The peak charging power reached 97 kW, and the average was 74 kW. For the serial version, Kia claims a charging time from 10% to 80% in 30 minutes.
The second result in the test was shown by Hyundai Inster: with a claimed range of 360 km, it lost 104 km, or about 28.9%. The Kia EV4 participant, with an 81.4 kWh battery and a nominal range of up to 594 km, lost 204 km. Overall, most electric vehicles this year showed weak results — for example, the Lucid Air missed about 440 km from the claimed range.
