Good morning, everyone.
I've always been curious just how much of a difference the heat pumps make compared to the PTC heaters that pre-2021 Teslas have used. I had a 2019 Model 3 SR+ for two years up here in Minnesota, and I was always frustrated with how much range that I lost in the cold.
I'm finally starting to get some data on my new Y, and I've been really impressed! During those two years, I never had the chance to drive the 3 in weather as cold as we've seen recently. And my Y is more efficient at higher speeds in -10º weather than my Model 3 was at 0º. The difference isn't small, either. This from Teslafi:
Coldest drives with my Model 3:
Coldest drives so far with my Y:
As you can tell, I need to get a lot more miles in these temps to firm up those conclusions. But my Y is an LR AWD model which should be less efficient than the low-slung RWD 3, all things being equal. Both cars are riding on the same ugly-looking 18" Enkei wheels and snow tires, so they have an aero penalty. I blame the noisy racket they call a heat pump for the improvement. Color me impressed, though. This thing is much more usable in the cold weather than my 3 ever was.
