Across my 25,000 miles of road trips, I've averaged 2.8 MPK on most (AWD ER). 2.4 was the worst (winter), 3.0 the best (summer). Most of those are 75-80 MPH speed limits.
Makes sense, our speed limits are lower and I tend to drive the MME slower than my other car , maybe 5 miles above of the speed limit.
We don't compromise. Normal speed, normal cabin heating and cooling (71-72F). Unless we're desperate which only happened once (strong headwind and arrived at 2% instead of the usual ~20% for that leg).
I don’t compromise, our max speed limits in NY area are 65 and many lower, 55, so I generally go 5 mph over speed limit, ride is enjoyable and I get better range
It does if you start with 100% with an extended battery. I have done it here in Florida and up north during the summer. Haven’t tried in the winter .
Depends on the heat pump. Modern cold weather heat pumps work well below freezing, some into the single digits or even lower. Not sure about the state of automotive-grade heat pumps, but the technology is available to make them work well below freezing.
My point exactly. You had much better temps than the OP, and I suspect you were driving under 70mph. Can it be done at lower highway speeds under optimal conditions? Sure. That is an outlier.
If it is using motor waste heat, like Tesla and GM, then this is not an issue. A person who got a Hummer early on, road tripped it last winter and got very little range loss. His fast charges all started at 250kw to 300kw even in cold weather due to preconditioning using the motor waste heat.
...except for West Virginia.
work out the math though. You’ll always be better off driving as fast as you can and getting worse efficiency if your goal is to get to your destination as fast as possible. It’s more likely that differences you and OP are seeing are due to difference in trim or other factors
You obviously haven’t used modern heat pumps from the last 20 years. New home mini splits are amazingly efficient, even below freezing. The heat pump in my Tesla model 3 did a great job down to 25F (the coldest it got while I owned that car). I’m not saying they are great at the extreme temps some people apparently deal with (-30F? Screw living there), but they would absolutely improve the crappy range I get in my MME at 30-45F. There’s no excuse for having such range loss in above-freezing, mild climates.
