As a Minnesotan with an unheated detached garage, I’d be very interested to know about -40°F performance. We get a couple of those days every year. I have been looking at my next car potentially being an EV and am really curious about the extremes.
I make sure the displayed range on the M3 is double for the distance I want to travel. Winter tires, snow and ice sticking to the car, and -15C are quite normal occurrences here, and range display is pretty consistently half of what to expect.
Does the nav system do a good job of compensating? The "normal" display on the 3 is based on the EPA rating and is always wrong, but when I navigate, I find the trip range thing to be quite accurate -- even factoring in upcoming hills and traffic.
Average over 130000km (3y) is 191Wh/km
Winter can be as bad as 330Wh/km (-30C 110km/h)
Summer can be good, but I've never seen a 100km trip better than 145Wh/km.
Generally the lower the remaining range, the better the EPA range (estimate) is.

I live in the north and I will not by an EV until the range reaches Gas Autos when the Temp is below 0F with the heat blasting. Getting caught in the cold without fuel is not good. And I wonder if Wind Chill can decrease range even more.
I fully believe all EVs are tested and developed for the Southwest US, ignoring real conditions many people encounter.
Wait, judging from some comments people actually take heating and winter tires into consideration when calculating differences in mileage? But I have to disagree. You have to use heating and winter tires during winter. The correct calculation should be take that out first and then compare the numbers. For example if heating and winter tires take say 100 miles, full mileage says 500, but car stops around 300 miles, th…
My fuel economy drops about 20% on my petrol car in cold weather city driving. I don't know what causes the difference, perhaps waiting for the car to warm up and windows to defrost.
EVs upsides and downsides should be considered without it needing to be a comparison to ICE. But, yes, running the heater will use fuel. In this case EVs with "250 miles" range are losing 30%~ of that range for three months of the year and a further 20% over the first three years of their life, making them reliably closer to a 140-mile vehicle. People who are planning round-trip travel or commuting need to know this…
Many places in the US, it is more than 3 months :)
Interesting data, but for the Model 3, I think an important piece is missing: model year. Around 2021 they switched out the resistive cabin heating for heat pump heating, which had a positive impact on cold weather range. Anecdotally speaking, my 2020 Model 3 gets between a 30-40% range hit in the winter.
This article is about battery capacity loss due to cold weather (either directly or due to use of battery-heaters). Cabin heating is over and above the loss discussed here.
That should give reduce the energy used for cabin heating, reducing range loss, perhaps by half for longer journeys.

A lot of ICE cars won't even start at 40 below. Those cases should count as zero mile range
not such a foreign idea when you have to do that for Diesel to get them to start in the cold.

Winter tire (if you have them) and heating are the likely culprits!
Winter tyres though and winter fuel mixes? Those definitely have an effect.
I find it strange that the charts only go down to 20°F, when for example at the moment I write this comment, it's -5°F (-21°C) in Bismarck, North Dakota. And sub-zero Fahrenheit temperatures are pretty common in the winter across the Northeast, especially at night. "Normal" driving conditions extend way below just 20°F.
