Calling my numbers "lunacy" will, unfortunately, not change the laws of physics. If you drive twice as fast, air drag multiplies by four, and the energy to overcome that air drag has to come from somewhere. At highway speeds air drag is the only appreciable force at work. Tire drag makes a little bit of difference too, but that will be more than canceled out by the fact that ICE efficiency drops at higher RPMs.
Your "long-haul truck" citation is irrelevant to this discussion because those numbers are for drastically slower speeds than the ones you're talking about.

As you will. Not that this changes a thing, the Model S's efficiency will also drop further, thus further lowering its range. The issue remains, even driving at inane speeds, the Tesla will have a significantly lower range than the 535d.
