I read that the Tesla MY is good for this, including a camping mode designed for it. I suppose an M3 might also work, but would have less room to stretch out?
Are there other EVs that would be good for this, with a heat pump, something that’d serve as a camping mode, and enough space for two people to lie down and sleep with the back seats folded down?
On our Ioniq 5 the heater seems to take around 0.8kw once the car is warmed up to maintain the temperature, so assuming you arrive with a 60% charge you could run it for about 50 hours. And that’s with it set on 74F, if you kept it at about 66-68F and got in your sleeping bags it would use less power.
I’d cook at 74! What were the outside temps? Certainly not winter cold…
