What would expect the Hybrid Heater in an SV Plus with winter package when turned on do the the mileage?
Assuming the 2019 is the same as the 2018, I have a 2018 SV with weather package. Running the heater dips my range and lowers my efficiency a bit but not nearly as much as running the front defroster. But it also depends on the temperature. What I have noted is that is starts probably with the PTC heater for a minute to get heat into the cabin but then must switch to the heat pump. I have watched the climate control energy draw and it starts fairly high but then quickly bumps down to about the same as the A/C. But on colder mornings, below freezing, that bump down is not as much. So on a cold morning running the heater I might get 3.3 miles per kWh. This morning was not as cold so I got 4 miles per kWh. But if I use the defroster that power draw seems to stay much higher and its not rare to get around 2.5 or so miles per kWh until I turn the defroster off. That same drive without AC or Heat averages around 4.5 miles per kWh.
NOTE that my driving in the morning is very short, so naturally these numbers would bump up on a longer drive once your car was warmed and defrosted. I do not pre-heat either. No need on my short drives.
