Can someone tell me if the B-Class uses a heat pump for cabin heating/cooling? I presume not, since I have seen no mention of it, but I've never seen it in a Tesla spec. either. I think the Leaf is the only car that owners brag about their heat pumps.
And if you're going to sit in the car and eat lunch, does it make any difference if the car is ready to drive or not? I mean you can pull up and just sit there, or you could switch the ignition key off and on, without going that extra step to "start" the car. I think in some cars the 12V battery provides power until the car computer activates the high-voltage. So I suppose I could be running down the 12V battery. If I get a chance to put a voltmeter on the 12V battery in both modes maybe I can tell.
In general I wish I could find a little more technical information on what's going on inside this car. No Haynes manual for us.
