The Norwegian media outlet Motor.no, in collaboration with the Norwegian Automobile Federation, conducted its annual winter range test featuring a variety of vehicles, including some exotic Chinese models available for purchase in Norway. Each year, they conduct both a winter and a summer test to assess the real-world performance of several popular cars. As is widely understood, WLTP ranges can be overly optimistic, prompting the question of how much they differ from actual mileage.
This year, the Long Range (LR) trim of the Model S outperformed the Model 3 LR Dual Motor's previous record of 530 km, achieving a notable 530 km in the test, while the Model 3 managed 521 km. Interestingly, the Model S faced a slight disadvantage, as it could only charge up to 98%.
Given Norway's harsh winter conditions—average testing temperatures ranged from -5°C to -10°C, with a small part of the route dipping to -19°C—conducting tests in this environment is quite relevant. Motor.no reported on the specific route they utilize each year for winter testing.
Route: From Oslo, around Rondane National Park and back
Typically, cars lose anywhere from 20% to 30% of their WLTP range in these conditions, though some models, like the Tesla Model S, exhibited minimal deviation, losing only 16.40%. The Maxus Euniq6 also performed well, with a mere 10.45% reduction in range. The MG Marvel R and MG 5 maintained respectable figures, deviating by 16% and 17%, respectively.

On the opposite end, the Mercedes EQE 300 faced a significant drop of 33.39% compared to its advertised range but managed to exceed 400 km in actual performance. Similarly, the Chinese Hongqi E-HS9 experienced a decline of over 34%.
The least favorable performance came from the Toyota bZ4X 2WD, losing 35.79% of its range. Notably, Toyota opted not to release the 4WD variant due to its poor performance in previous range and consumption tests, leading the company to plan necessary updates before further evaluations. This situation is mirrored by the Subaru Solterra, which is identical to the bZ4X in specifications.
Similar testing results were also seen in the Chinese winter tests, where the bZ4X again fell short of expectations.
The testing list included 12 Chinese-made cars, some of which are set to be launched in Europe soon, such as the JAC e-JS4, Voyah Free, BYD Atto, BYD Han, and Nio ET7.
