Technically, a RAM 1500 BEV, could easily take the Cd 0.357 of the ICE variant, and with the clean underbody of the electric, plus the minimized cooling requirement of the BEV power train, easily come in at Cd 0.30, to match Cybertruck, IF it keeps the OEM full tonneau cover.
General Motors 'invented' the aeroshall, and military HUMMERs have used a variation of it. We'll have to wait and see if it becomes available as a high-performance option, as our own Brett Herndon tried for FoMoCo.
AeroStealth owned one of Brett's F-150 'Cybertrucks' in 2014, although it did require Brett's aero boat tail to get Cd 0.3.
The big issue with trucks isn't just their bad CD, it even gets multiplied by their large frontal area.
And since electric motors don't gain efficiency under load like internal combustion engines do, the issue will be more significant with electric trucks.
If you compare the CDA of a Tesla Model S with that of such a truck without a cover, you will see that the truck will get less range out of a certain sized battery on a highway driving the speed limit.
And that's where range matters the most to the average consumer.
