Did you actually read Ford’s recommendations? They absolutely do say use heated seats and heated wheel and avoid trying to use the HVAC to heat the whole cabin.
Ford’s advice boils down to garage it, leave it plugged in whenever possible, preheat it while plugged in before you go anywhere, make sure your tires are properly inflated (duh), and use the seat heaters and heated steering wheel instead of the HVAC.
All in all, a bunch of kludges or otherwise obvious actions to fix the inherent limitations of the vehicle. But keeping the truck garaged and plugged in all the time is not practical for most users, particularly when used as a work truck. I sure as heck wouldn’t want to be out in sub-zero temperatures relying on seat and steering wheel heaters to keep me from freezing while trying to make it home before my vehicle dies, especially when I just spend upwards of six figure to buy it. It is all fine and good if you live in the south or the west coast, but if you live in the northeast or upper Midwest or mountains, this truck isn’t going to work for you.
You really lack reading comprehension skills, don’t you?
I said, “Ford doesn’t recommend relying ONLY on heated seats.” Emphasis has been added for the reading impaired. Nothing, at least as quoted, says anything about not using the HVAC. But yeah, that does use power.
Yes, Ford is advising people how to maintain optimal range in conditions which are sub-optimal for their batteries. No, they are not recommending extraordinary measures like demanding you drive it unheated.
