Going slower does mean you experience a lot less air drag.I don't think off-road expedition use is going to be the forte of the Cybertruck. Just because you are going slower off road does not mean you consume less energy
But you likely experience more rolling resistance, because you're off-pavement, may have uneven terrain, and may have reduced tire pressure.
I don't know which factor is dominant. I'd say it's time to start measuring things.
A hybrid pickup truck (like the Chevy Silverado Hybrid or GMC Sierra Hybrid) is probably the best model available to measure this tradeoff. It's not a great model, because its not-as-good-as-the-Cybertruck aerodynamics are going to exaggerate the savings from driving more slowly -- but the CVT keeps the gas engine in its sweet-spot at a wider range of torque*speed requirements, so the ICE and gearbox quirks will be minimized. As I said, it's an imperfect model.
Alas, I'm too busy working to go out and measure this at the moment.
