US study: Tesla models halve their range in winter
A study by the US law association Vaziri Law Group has published an overview of the most unreliable electric cars in winter. Data was collected on four main criteria for each EV model: Verified range loss in winter, accidents in winter (3-year period), charging time (10 to 80 percent) with DC fast charging and usable battery capacity. Finally, the unreliability in winter was calculated from the combination of these values. According to this, the Nissan Leaf is the most unreliable electric vehicle in winter with a score of 77.59 points. It is closely followed by the Tesla models Y, X and S, all of which halve their range in sub-zero temperatures.
The Nissan Leaf's longer charging time of 59 minutes was rated as the most serious shortcoming in addition to the range loss of minus 38 percent in cold temperatures. With 76.14 points, the Tesla Model Y took second place, recording one of the highest range losses in winter at minus 52 percent, the second largest in the study. In addition, seven winter accidents raise concerns about its driving behavior in icy conditions, according to the Los Angeles-based advocacy group. However, its 27-minute charging time is a slight advantage for those who want to charge faster in winter, it said.
The Tesla Model X also has to contend with identical range losses of more than half, ranking in third place with a score of 75.88. The Tesla Model S, on the other hand, shows the greatest loss at 55 percent, taking fifth place in the study with nine winter accidents. In between, the VW ID 4 ranks fourth, for which the study shows zero winter accidents and a manageable range loss of 35 percent.
BMW i3 and VW e-Golf follow in 6th and 7th place with relatively low range losses of minus 15 percent and 12 percent, but 40-minute charging times in both cases. The Hyundai Ioniq recorded the lowest loss of winter range at just minus 3 percent and also the fastest charging time in the study at 16 minutes. The Chevrolet Volt Hybrid had the longest charging time of all 16 models examined, at 210 minutes, despite having the lowest battery capacity of 18.4 kWh. Most winter accidents are attributable to the Tesla Model 3, which also stands out negatively with a range loss of minus 50 percent. (aum)
