I think part of the problem is that the MachE often gets better range than its EPA estimate and people were banking on the Lightning following suit.I didn’t watch the video - I rarely watch them for the very reason you state in paragraph 2.
Did he mention the prevailing wind speed? That’s very relevant.
Ford didn’t “sandbag” on range. They are required to use EPA test method numbers. Highway-only will always be worse.
Instead maybe we're seeing just how much of a penalty the large frontal area hits you with. In addition, the EPA test uses pretty low speeds for the highway test, and since velocity is squared when calculating drag force, the force required to move something through the air just a little faster gets pretty high pretty quickly.
It would be better if the EPA used higher speeds for the test so the estimate could be more accurate to real world speeds, but here we are.
