I live in Minnesota where below zero winter temperatures are common. One day driving home on the freeway with the temperature at about -17 degrees, I saw a Chevy Volt struggling to make anything close to highway speed. Other than a small peephole on the drivers side windshield the windows were frosted over. The small gasoline engine, that keeps the batteries driving the wheels topped off, was screaming from trying desperately to keep the batteries going.
The Chevy Volt is not a true EV, but a plug in hybrid with a small gasoline engine. I would expect that any EV in those temperatures would be struggling not only with range, but to keep the windows clear and the passengers barely comfortable. My wife is driving her third hybrid Ford Escape and loves it. However, we know from experience that when temperatures get below zero the gas mileage will drop 30-40%. Because the gasoline engine in her hybrid still drives the wheels we have little fear of being stranded.
Some folks are going to have to get stranded on the highways in northern climates in the dead of winter to “get it”.
It is best to learn lessons the hard way.
