It'll sap the range of any kind of vehicle, but refilling an EV is a whole lot cheaper, so higher speeds are more economic for an EV than a petrol car. (Assuming you don't reach the point of running out in the middle of a shift of course)
How's that? The increase in work required is the same, unless the ICE somehow gets more efficient at those speeds (in which case it's been geared pretty badly) the impact is going to be the same. If anything it'll be worse as an EV powertrain is efficient across a broad range of speeds whereas an ICE can only operate efficiently in a narrow rev range.
The EV is more efficient, but the energy density of the battery is much, much lower than gasoline. The ICE wastes most of its fuel energy as heat with a fraction going into actually providing drive. An EV being 99% efficient has its range being entirely dominated by air & rolling resistance, whereas for an ICE car the relative impact is lower.

But that fraction is constant however big the drag is. If there's twice as much drag etc. then you're going to burn twice as much fuel and your engine will run hotter, it's not like the heat is some fixed overhead.
