Hi everyone, Probably a n00b question, but I *AM* a Tesla newbie so here goes: (I did do a bit of searching but didn't really find this particular question) I charged my M3 Performance to 100% at home overnight. The car says it's fully charged, and that range now is 293 miles. I believe it's advertised at 310 miles. Why is there a difference? Edit: I should clarify: I don't really care about those 17 miles, I'm just wanting to learn and understand.
