Sigh. I disagree with the Forbes numbers that describe my situation, and do so inaccurately based upon my first hand experience. The article claims that Leaf range drops by -58% at 20°F. I am telling you that that is absurd based upon my own first-hand experience at that temperature and below. I am seeing more like a 35% drop down to 0°F, and that is partially due to snow tires.
As for your concern...correct, I do not drive around in the winter with the windows all fogged up and unable to see. We do use defrost settings and cabin heat in the winter time. We just don't put it on 'max' and leave it there 100% of the time. That is the only way I can **imagine** getting the mileage that low. I could also drive an ICE car around with the handbrake on, and then write about how ICE cars get bad mileage...and did you know that the hand-brakes fail too often?
It also appears that you misunderstand my situation and think I live in Florida, and have never logged any miles below 50°F. In my first post I was careful to report a modest decrease in range, and at what temps my first-hand experience extends to. IF you would prefer to think the car shuts down and becomes a brick a couple degrees colder than my experience...so be it. But that is neither what the Forbes article says, nor what thousands of Leaf drivers in Norway report.
In summary: my wife and I have to drive in black ice, light snow and temps down to the single °F and we have found the leaf to be the best winter car we have ever owned....it starts reliably, warms up the cabin and seats quickly, and its low weight distribution and traction control give it amazing handling on ice and snow (w/ snow tires). While the range does drop as much as 35% at our winter temps, that is not a problem for **us**.
Based on that experience, I can conclude that future 200+ mile BEVs will also be great, reliable winter cars, contrary to the intuition of non-EV drivers that think that all batteries stop working below freezing, and Forbes magazine. Whether the BEVs will be useful in Northernmost Ontario, Manitoba and Saskatchewan, will depend on the fraction of trips owners will need to take in the dead of winter that are well over 100 miles, whether it is their second car (as here) and the future presence of high-speed chargers there, which is unknown.
