The Hummer is a Beast in the snow. Amazing how good it drives and plows thru the snow.

The Hummer has some advantage in cold weather compared to other EV's. GM decided that they didn't want to make the vehicle more efficient, so they achieved the amazing range (for a vehicle of that size and weight) by slapping a 220 kwh battery into it (more than twice what I have in my Model X Plaid).
The better the efficiency of an EV, the higher the impact of accessory use.
If the heater pulls 4 kw in a Model X, it's reduces the range twice as much in a Model X than in a Hummer EV even if their HVAC consumes the same energy.
No matter if it's AC or Heat or any other accessory, accessory use affects the more efficient vehicles more than the less efficient ones.
Tesla and Lucid focus on making vehicles as efficient as possible, requiring a smaller battery to get a longer range. However, the down side is that accessory use will have a higher impact. There is only so much you can do to improve HVAC efficiency.
