Final week, we noticed a quite complete winter check finished in China, evaluating totally different EVs and the way they deal with the chilly.

And as you’d anticipate, the precise vary drops considerably.

Not like within the earlier check, all vehicles had been examined with the local weather management set to 24 °C in auto mode. The check was finished on rural roads with the typical velocity round 50 km/h. All automobiles had been pushed till depleted.

This time round, the check contains greater than 40 fashions and a bit extra world fashions, together with contenders from Tesla and Mercedes.
