Sharp drops in temperature during winter become a real challenge for electric car owners. In severe cold, batteries lose a significant portion of their range, directly impacting convenience and cost-effectiveness. A recent large-scale test in Norway revealed that market leaders were not as resilient to frost as expected. In contrast, Chinese manufacturers surprised with results that have shifted the balance of power in the market.
During the test, conducted in the suburbs of Oslo, temperatures dropped to -32°C. Under these conditions, 24 different electric vehicles—including European, Korean, and Chinese models—covered the same route. All cars drove at real-world speeds, using regenerative systems and climate control. The main goal was to determine how much range is lost in extreme cold, and which models can withstand these conditions better than others.
Losses by the numbers
On average, participants saw a 38% drop in range compared to the official WLTP standard. Some cars lost up to 46% of their range, coming as an unpleasant surprise for many drivers. However, two Chinese MG electric vehicles—the MG6S EV and MG IM6—recorded the lowest losses: 28.87% and 30% respectively. Placed between them was the Korean Hyundai Inster with a result of 29%.
The MG6S EV, with an official range of 485 km, managed to cover 345 km before the battery was completely depleted. The MG IM6, rated for 505 km, reached 352 km. For comparison, the Hyundai Inster, which claims 360 km, drove 256 km. These numbers clearly show that Chinese batteries proved more resistant to cold than many competitors.
Technology and expertise
According to Autobild, MG’s success is attributed not only to advanced technologies, but also to the expertise of its parent company, SAIC Motor, which has been developing and producing electric vehicles for over a decade. Collaboration with the world’s largest battery maker, CATL, also played a significant role. The joint venture established in 2017 enabled MG to implement cutting-edge battery solutions, which became evident under Norway’s extreme conditions.
MG batteries use chemical materials that help lithium ions remain more mobile at low temperatures. This reduces internal resistance and allows for more efficient energy consumption. In addition, some electricity is used to maintain a comfortable cabin climate and heating systems, which also impacts the final range.
The market is changing
Test results in Norway may change how European buyers perceive Chinese electric vehicles. Until recently, many were skeptical about the quality and reliability of cars from China, but practice has proven otherwise. Under harsh winter conditions, MG not only held its own but even surpassed recognized market leaders. This could prompt other manufacturers to rethink their technologies and pay more attention to battery performance in cold climates.
Buyers living in regions with severe winters may now reconsider how they choose an electric vehicle. Fuel savings and eco-friendliness are important arguments, but without a reliable battery in freezing temperatures, these advantages lose value. Chinese brands seem to have found a solution that works in reality, not just on paper.
MG is a brand that was originally British, but since 2007 has been owned by the Chinese corporation SAIC Motor. In recent years, the company has focused on electric and hybrid vehicles, actively introducing innovations in battery technology and energy management. Thanks to close cooperation with CATL, MG has managed to create batteries that maintain high efficiency even in extremely low temperatures. Today, MG is becoming an increasingly prominent player in the European market, offering cars with good value for money and real advantages for life in cold climates.
