Imagine the fuel economy if towing too! Let's be sure we are comparing apples to apples here.
The truck claims comparability with 250kW chargers. That's a lot of power in, but power electronics make that very viable these days if the grid can support it.
Keeping the battery in a reasonable state of charge range, like you would your fuel tank, means that charging is much faster than hours or days.
I'm in no way an eV apologist. I'm much more pro-hybrid, which would include significant benefits for hauling and towing due to the significant low end torque.
But let's at least be sure we're comparing requirements and concepts of use consistently.
Musk said he used the f-150 as the baseline.
f-150 trucks have beds as short as 5.5ft and tanks as small as 23 gallons.
The ecoboost 4x4 yields 24mpg highway, and 25mpg in the diesel.
Unloaded.
Loaded up it's how much worse?
23 gals x 24 mpg unloaded is over 500 miles range. In best, ideal highway conditions. Start hauling and getting 12 mpg, and the range goes way down there as well.
The issue with the low end cybertruck is that there is NOT a 500mi range. Besides being uuuhhgggglllyyyy, the low end not making unloaded range is an issue
But, assuming it is decked out, the price of the fast, 500mile tri-motor version isn't far off from an f-150 king ranch or platinum.
The physics of higher load resulting in higher energy use is not earth shattering, nor unique to one approach.
