My Mustang Mach-E standard range AWD has a published 211 miles range but summertime highway at highway speeds its good for just shy of 240 miles.

EPA range and highway range are two very different things. EPA being combined is very accurate for the Lightning. And I beat the range estimates the truck gives me regularly. If you travel over 70mph in a vehicle shaped like a stack of bricks, the range will drop quickly. Keeping it at a reasonable speed nets big improvements. I've traveled on many back roads trips resulting in 320-350 miles of range, and secondary highways at 50-55 and got between 300-320. Not only does range go up, but stress goes down the slower you go. Nobody needs to be in that much of a hurry.
