Agreed at first I was puzzled when people started posting the screenshots as the efficiency was higher than mine, then I started calculating the average speeds and was relieved when their average speeds were lower.
Rural driving might explain it. When I drive on largely non-stop 50-55 mph rural roads, I get exceptional range.Honestly, I don't really know. As you can see from below, I've averaged 3.5 miles/kWh over 12,600 miles. This includes very cold winter driving, typically below or well below freezing during winter months, during which I'm closer to 3 Miles/kWh or slightly less. The car is garaged in a heated garage (typically about 45 F during the winter.)
I typically drive gently, and my local driving is pretty rural, with typical speed limits between 35 and 55, and I generally obey speed limits. But I also do a fair amount of Interstate driving with a 70 mph speed limit. I almost never exceed 75, and that may be part of it. I keep my tires at 44 psi. In case anyone cares, btw, I have a rear wiper which doesn't seem to be hurting the efficiency, for those who think it might. I do not avoid using heat or a/c, setting those to whatever makes me and my passenger(s) comfortable. I use seat and steering wheel heating during cold weather.
