    I’ve got the 2021 Kona EV and while you do lose range in the winter, it’s more like 100km/450km. That’s with intense grip heavy winter tires and the heater running. In Ontario, so regularly ran it with -35c temps. It’s cold and you lose some range, but not 400miles out of a 700mile range

      In general Li ion batteries lose about 40% charge efficiency in normal cold weather. It’s up to the car’s systems to keep the batteries heated to reduce that, at the cost of constant power draw. In our experience with similar weather it’s not far off, and for safety reasons we just assume half the battery is lost during winter driving. Mountains add into that, but aren’t ultimately super extreme.
