I've read that multiple things come into play when watching the battery mile meter (weather, driving style, hills, Hvac) What's deemed "normal"?
I drove a used base,24k on it, started with 63 miles on the gauge. Total of about 8 miles, AC on and highway driving included. Got back to the dealership, the gauge said 61.
Test drove a loaded model, 21k on it. 24 miles on the gauge, 5 miles, no highway driving, two "boost" thrusts with the AC set to low and when we returned the gauge was at 19.
Does that sound about right?
