The Norwegian media outlet Motor.no, in collaboration with the Norwegian Automobile Federation, conducted its annual winter test featuring a variety of vehicles, including some exotic Chinese models available for purchase in the country. Each year, they perform both winter and summer tests to assess the real-world performance of popular vehicles. Given that WLTP ranges are often optimistic, it’s crucial to understand the actual mileage difference.
This year, the Long Range (LR) trim of the Model S outperformed the Model 3 LR Dual Motor's previous record set in 2021, achieving 530 km compared to the Model 3’s 521 km. It's worth noting that the Model S had a slight disadvantage, as it could not charge beyond 98%.
As expected, testing in Norway presents challenges, with average temperatures ranging from -5°C to -10°C, and some parts of the route experiencing temperatures as low as -19°C. Here’s the route that the testing team follows each year.
Route: From Oslo, around Rondane National Park and back
Typically, vehicles lose between 20% and 30% of their WLTP range under these harsh conditions, with notable exceptions. The Tesla Model S exhibited only a 16.40% deviation, while the Maxus Euniq6 only lost 10.45%. The MG Marvel R and the MG 5 also performed relatively close to their WLTP figures, with deviations of 16% and 17%, respectively.

At the other end of the spectrum, the Mercedes EQE 300 experienced a significant decline, losing 33.39% of its advertised range. Despite this, it managed to surpass 400 km of actual range. Similarly, the Chinese Hongqi E-HS9 saw a decrease of over 34%.
Unfortunately, the Toyota bZ4X in its two-wheel-drive variant was the weakest performer, suffering a 35.79% reduction in range. Notably, Toyota has withheld the four-wheel-drive model due to its poor performance in previous range and consumption tests. Updates are expected before it undergoes further evaluation, similar to the Subaru Solterra, which shares the same platform.
Recent findings from the Chinese winter tests showed similar disappointing results for the bZ4X.
This year's list also featured 12 Chinese-made vehicles, including those soon to hit the European market: JAC e-JS4, Voyah Free, BYD Atto, BYD Han, and Nio ET7.
