The Norwegian media Motor.no organized a large test among 28 electric cars to compare their autonomy in very cold climates. And finally it was the Tesla Model S that stood out, having managed to travel no less than 530 kilometers on a single charge. A real achievement.

If things have improved remarkably over the years, autonomy is still today one of the main obstacles to buying an electric car. However, manufacturers and equipment manufacturers are constantly developing new batteries that allow more energy to be stored, such as semi-solid batteries. A kind of transition pending the rise of solid batteries, which will not arrive for several years according to specialists.

Cold: the enemy of electric cars

Meanwhile, it is still impossible to reach the symbolic bar of the 1,000 kilometers, although some cars like the Zeekr 001 or the Lucid Air come close. This is due to the innovations of certain companies such as CATL, which designed the Qilin CTP 3.0 battery capable of offering record autonomy, as well as ultra-short charging time. Because it is also importantreduce the time spent in the terminalto go further, faster.

This is demonstrated in particular by the Norwegian youtuber Bjørn Nyland with his 1,000 kilometer test where the Nio ES8 particularly shone, as did the Volkswagen ID. buzz. But this test measures the autonomy of the cars in highly variable conditions, with temperatures that are sometimes negative or that exceed 20 degrees. This can bias the results.

Because we know that the cold and electric cars do not mix. In fact, the batteries must be at an optimal temperature to work, which requires a lot of energy. So, autonomy is visibly decreasing, especially if you also use the heating and do not have a heat pump. But sometimes it is difficult to concretely quantify the evolution of autonomy between summer and winter, while certification tests are generally carried out under optimal conditions.

Norwegian media motor.no wanted to investigate. To do this, the journalists compared 29 electric cars, driving them until they broke down. under negative temperatures, between -5 and -10 degrees Celsius. All segments and manufacturers were then represented in this life-size test, with the Nio ET7, Volkswagen ID.5, Mercedes EQE and the Renault Mégane E-Tech, among others.

Very good note for Tesla

Of course, Tesla cars also went on the grill. And the least we can say is that they did pretty well. Finally, especially one, the Model S in this case. In fact, theThe electric sedan will have managed to travel 530 kilometers on a single charge, during this test that took place between Oslo and Hjerkinn. Thus, it is the only vehicle that has exceeded the 500 kilometer mark.

The place InsideEVs specifies that the previous record was held in 2021 by the Tesla Model 3 Grande Autonomie, with 521 kilometers. During this test, the Model S lost only 16.4% autonomy compared to the announced WLTP value of 634 kilometers. However, the Norwegian medium specifies that the sedan could have gone further, but that a technical problem has prevented from filling the battery more than 98%.

The Model S is followed by the BMW i7 xDrive60 with 424 kilometers, 27.74% less than its announced autonomy, with 595 kilometers according to the WLTP cycle. Then comes the Mercedes EQE 300 which also did very well, having been able to cover up to 409 kilometres. However, the difference with the approved figure is of the order of 33.39%, while the electric sedan normally promises a range of 614 kilometers.

At the bottom of the ranking we find the Maxus Euniq 6, a large SUV that is currently not marketed in France but in Norway, like the Nio, BYD or Xpeng models. So he was able to travel only 317 kilometers, against 354 announced. The MG Marvel R is doing a little better, having covered 308 kilometers, while its range is promised at 370 kilometers WLTP. Finally, the MG 5 truck completes the bottom of the table, with 313 kilometers.

In winter, the autonomy of electric cars decreases with the cold: here is the ranking

The range of an electric car varies greatly depending on road conditions and temperature. But to what extent? This is what the Recurrent company wanted to know, which has compared twelve different models in winter. And the…
