I would expect a centrifugal heater fan to draw about 6-800 watts on full power. As they only use resistors to provide slow running, this just wastes power. Therefore on a 4 hours trip, about 3Kw of power is used, a bit more from the HV battery - say 3.5 Kw. That's 3.5kW that you cannot use for powering the car. Also, in terms of the GOM, as soon as you turn on the HVAC system, it deducts about 20mile per hour from your GOM reading. That doesn't change anything really, of course, but it does make you a bit edgy. For max miles,
As you cannot actually change the rain, wind, temperature, incline etc, - HVAC you can influence and it must be off.
