DeaneG said:Funny thing - When you ask the car to precondition (fixed at 74 degrees), and have the dashboard climate control set for 70 degrees, you are telling the car to preheat to 74 then immediately spend energy cooling back to 70 as you drive away.
Isn't auto CC set to 77 degrees? Which makes your scenario that much worse. Best to just leave the CC off for the first few miles.
BTW, that's a common mistake I seem to be making of late...now that I'm coming home with the A/C on - forgetting to switch it off before I set out again the next morning. I mean I do catch it in pretty short order, usually the first time to see what projected range my overnight charge has given, so it's not a massive deal.
