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.

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.
The energy app shows you live estimates based on distance, elevation, wind speed, temperature, humidity, tire pressure, cabin climate load, and even your phone charger.
As a rule of thumb I halve the EPA estimate in winter and 2/3-3/4 it in summer.
I have had no range issues doing this for the 130000km + I have owned the vehicle.
Edit: If I'm going to tap, I check the Wh/km, as that is what I'm used to. It was better before they removed it from the swipe, but hey, we gotta fill those sprints somehow.
