I have MYLR with 19" Wheels. Pressure is around 40psi all around. It was a bit cold this week in the high 30's low 40's all week in the mornings. I assume all those factors played into the numbers I am seeing. Not too worried about it now. Just wanted to be sure I wasn't seeing an issue.Speed and HVAC use are just some of the variables used to determine efficiency,
Do you have MYLR or MYP? What kind of tires do you have? What size tires you have on your vehicle? What was the tire pressure? What was the outside temperature?
There are several variables that impact efficiency, and therefore battery consumption.
P.S. The more mileage you put on the car, the lesser range anxiety you will have.
