The Norwegian outlet Motor.no, in collaboration with the Norwegian Automobile Federation, conducted its annual winter range test, featuring a variety of vehicles, including several luxury Chinese models available for purchase in Norway. This test, alongside a summer counterpart, aims to assess the real-world performance of popular vehicles, as official WLTP ranges tend to be optimistic. The objective is to measure the actual mileage in challenging conditions.
This year, the Long Range (LR) trim of the Tesla Model S shattered the previous record set by the Model 3 LR Dual Motor in 2021 by achieving 530 km of range, while the Model 3 managed 521 km. Notably, the Model S faced a slight limitation, as it was unable to charge beyond 98% capacity.
The Norwegian climate poses significant challenges, making it a fitting environment for testing vehicles. Average temperatures during the tests ranged between -5°C and -10°C, with some parts of the route experiencing lows of -19°C. Here's the route the testing team utilized annually for their winter evaluations.
Route: From Oslo, around Rondane National Park and back
Under such conditions, cars typically lose between 20% and 30% of their WLTP range, with notable exceptions. The Tesla Model S only deviated by 16.40%, alongside the Maxus Euniq6, which fared even better with a mere 10.45% loss. The MG Marvel R and MG 5 also performed relatively well, deviating by 16% and 17%, respectively.

The Mercedes EQE 300 struggled in this test, experiencing a 33.39% drop from its advertised range, although it still managed to exceed 400 km. The range of the Chinese Hongqi E-HS9 also decreased by over 34%.
The least efficient vehicle in this year’s test was the Toyota bZ4X, which lost 35.79% of its range. The automaker withheld the 4WD version, as it performed poorly in previous range and consumption tests. Updates are expected before it is delivered for re-testing, a sentiment echoed for the Subaru Solterra, which shares the same platform.
Similar results were noted in a recent winter test conducted in China, where the bZ4X again failed to meet expectations.
The testing list also contained 12 Chinese-made vehicles, several of which are anticipated to launch in Europe soon—such as the JAC e-JS4, Voyah Free, BYD Atto, BYD Han, and Nio ET7.
