Too long. I drove 27 hrs straight through from NC to CO. Stopped about every 2-3 hrs to charge usually 30-40 mins. Would catch quick naps while charging. Cross country trips have always been in summer, so not much cold weather impact experience, but I’d say you generally will lose 10-15% efficiency in colder weather. If you run the heater (which I tend not to do), then that sucks power as well because you’re using electricity to specifically generate that heat vs. redirecting otherwise wasted engine heat. I will tell you that head winds in WY can have a 20% or more impact on the efficiency. There a good website (https://www.evtripplanner.com/) to help calculate range based on numerous factors such as car, battery size, tire size, payload, speed, wind, outside temp, inside temp setting (impact of running heat or a/c), elevation changes, etc, etc. It’s far more accurate than relying on just what the car says. It was hugely important in 2015 when I got my car and there weren’t near as many supercharges as there are now. There were some segments where it was sketchy as to whether you’d make it or not. I’d run it down to less than 5 miles of charge on a couple of occasions. That can be pretty nerve racking! With the smaller battery in the Model 3, they’ve now had to infill those longer segments on the major interstates.
