Nah. Speed is not the issue. Just climate. I've reviewed my stats and climate is at -5 and technique is at +3.4 give or take. I'm not like other Ontario drivers.
Respectfully disagree. The faster you go the more wind resistance, and the more energy it takes to move the car. The resistance graph line goes up like a hockey stick. Any car, gas or electric.
So, all things equal, you will be able to drive further on a charge at 45 MPH than at 90 MPH.
Yes, other things also impact range as well. At any given speed, the car with the resistance heat off will go further than the car with the heat cranked to the max.
It's cumulative. So the car at 45 with heat off will go much much further than the car going 90 with heat cranked to max. Now throw in traction loss for dry pavement vs wet/snowy pavement. It all matters.
