Renault ran tests of its battery-electric Zoe in way-sub-freezing temperatures in Finland and found that the EV compromised little in the way of performance, the French automaker said recently on its blog.
The Zoe, which was being tested in Finland's Lapland region, was subject to testing in the -25 Celsius (-13 Fahrenheit) range and experienced "almost unnoticeable" declines in performance. How unnoticeable? Specifically, Renault said, the car's defogging systems worked well, while the car's power and single-charge range were similar to those in higher temperatures. Renault engineers were "pleasantly surprised" by the performance of the car, which also gripped well on icy surfaces.
Renault was looking to address what some say is a major drawback of EVs, whose batteries tend not to perform as well in very hot or very cold temperatures. While it's true that most vehicles suffer some performance loss when the mercury drops, we like the idea of not being able to notice it.
