The video mentioned the heat pump in the SE, but it is ineffective at those temperatures. He did set the SE to quite warm (70 ºF), and I wonder how much the seat heating worked to keep the cabin air warm with no bodies in the seats absorbing the heat.

I use seat warmers to keep pizza hot driving home. I turn it on as I leave for the pizza shop to pre warm. Then again on the way home. They run just fine empty or not. I've only had F models with heated seats butt I doubt the car they had was much different with that.

Tommy said it's one of the coldest days recorded in Colorado at -20F (windchill included), but the temperature gauge was -3F at 3 hours of idling in the SE.
Since both seats on the SE were set to the max, I'm sure they warmed the cabin and the air conditioner had to activate (auto climate). You can see the AC light on at 6:06.

Noted. I’ve never had the bum warmer on if it weren’t under my bum.

Someone told me the trick way back when I had my CR-V. Been using it ever since. Granted I love pizza and the best joints don't always deliver more than a couple miles out, so we pick up often!Noted. I’ve never had the bum warmer on if it weren’t under my bum.

I hope nobody pays any attention to windchill on vehicle tests, since that measurement is for human flesh's evaporative cooling. Plus the batteries and motors are not exposed to surface conditions where the wind is. It was a good test, though. I think I'll be less conservative on heating during our typical subzero winter weather, and am going to try the seat heating trick with the empty passenger seat.

I don't. I paid attention to the actual numbers on the dash. If it is warm enough for the heat pump I expect better results than this. I do know my car sucked up way more battery in the negative double digits (actual temp) because of having to use the heat. I'm curious to know level of energy used by seats and if it would help when super cold. We have a heatwave of 55F today so I will try the seat warmer to help once it drops a little more.

Yeah I hate having to be that guy every time I feel compelled to point that out. All the wind can do to inanimate objects is speed up their cooling to ambient. If the car is already cold-soaked as in this test, the wind has zero effect.

All there seemed to be was a fire in the distance
I'm surprised you don't always have your battery % on display at the bottom of the instrument panel. That's what I look at when determining my available much range. In fact, because I have the Head-Up Display, the percentage the only thing I look at on the instrument panel. The Guess-O-Meter is for entertainment purposes only.
Edit: I also look at the instrument panel to confirm that my headlights are on.
Appreciate the idea. Might switch over to battery % and I turned my HUD off. Do you see a variance in the battery % vs the right hand side bar?
On another note, I truly enjoy this car. It’s just fun to drive.

The battery % at the bottom matches the gauge on the right, except the gauge is 8 segments so it's every 12.5% SoC for each segment. I've always thought one day I'd map what % causes a change in the lit segments in the gauge, but I haven't had the patience to do that yet.

Went to Ontario (Cornwall)Left home 100% start of charge and the GOM was showing “143km” range. Drove to the church ruins in Williamstown ON, then continued to Cornwall. Went to LCBO, Dollar Tree etc.
Hit the 401 with 25% ish SOC and planned to stop at a DC fast charger at Esso Vaudreuil and for coffee. Ended up using one at the rest stop after the border as I was falling asleep and my wife wanted the restroom. 17% SOC 181km driven since leaving home. Charged for 20mins, netting almost 12kwh. Cost? 4.35$. So charging at home is the cheapest but having to charge on the road is still almost half the cost of gas.
