Tesla claims to have 90..94% motor efficiency. With model Y using 13kW per hour, even if you count all 6-10% of this as heat, and manage to capture it, it'll still be hardly enough to keep the car at a comfortable temperature without additional heating. |

With home air-to-air heat pumps I took COP of 2-3 as a base for heating, it seems that COP=1 is a big deal in a car.
