Real World Heat Pump Effect

[Saghost]

It has not been confirmed that HP equipped Teslas will do lossy motor trick.
Stators already changed some time ago.
Also all that doesn't work if HP is out of refrigerant or any other error with the loop.

10kW is ok, nothing special. Many EV-s with HP can do that. Even cheapass 2013 Leaf.
Not all Teslas are equipped with 2 motors. That also matters.

Did you actually watch the heating mode videos linked above?

They specifically include drive motor heating...

Not sure what you’re trying to prove here - the data says even a single motor heat pump car has access to more cabin heating than my PTC car, and the far more common dual motor cars have significantly more.

Better technology - more power and better efficiency, with only a mild increase in complexity and failure modes.
