Heat Pump Cold Weather Range?

[therealpinto]

I still think a large reason for the heat pump is that "everybody" (read so called motor journalists) tend to say a heat pump is beneficial (so Ford added it to help sell the car). I support the techology as such (I have a heat pump heating my house in "sub-arctic" Northern Sweden), though.

What I think is still missing, is the information about total heat output of the two systems. The 5 kW heater is barely sufficient when it is cold and I would call it marginal when it is really cold (under minus 30C or minus 22F). Range is nice but I would be happy if my new 2025 LR AWD has the same cold range as my 2021 LR AWD but 2 kW more heat...

This is my suspicion, that maybe they didn't move the needle much on range but it's able to better keep both the cabin and battery warm at the same time. In my experience, the cabin has stayed a toasty 72F, but I've only driven the car down at 4F.

... and maybe the answer is more complicated than a bullet point. Heat pumps are more efficient than resistive heat at any temperature I personally encounter... 20 degrees F is about as cold as it gets here, and that is very rare... not even once this year so far. It's 45 F for around 4 months...

When I compare my Y (heat pump) to my MME (pure resistive) in terms of winter range hit (yeah, I know 45 F is not much of a winter for most of us), the Y loses a few percent over summer range on say a 60 mile round trip. The MME loses ~10% vs summer range. The difference is not nothing based on this non-scientific observation.
