Last winter was the first winter I drove my smart ED. It was a particularly cold winter, reaching temperatures of -30 degrees Celsius and below. I did not change my tires, instead opting to drive on my all seasons.
Considering the very cold weather, I thought the all seasons performed well. But what I had not taken into account was a slightly less than frozen winter, one where the car needed to be able to drive through a layer of slush.
Electric cars are amazing in that they have more torque than any other drive system out there, perhaps short of a jet plane. This can by very dangerous when driving on slush without proper winter tires. And I found out first-hand this year in just such conditions.
Because of the excessive torque, my car had a very difficult time sticking to the road when I encountered slush. It is not a good feeling to know your car is not turning the direction you have asked it to.
So without hesitation I have ordered, and am having installed, winter tires on both our company's smart EDs this winter. It is certainly better to be safe than sorry and have the confidence to know that you have done everything you can to help your vehicle handle varied winter driving conditions.
All this being said, I strongly recommend that EV drivers take a slow, methodical approach to acceleration during the winter, given the tremendous torque their vehicles have.
