At some point,Tesla will publish a paper for the SAE Congress,and we'll have their numbers.
If Cybertruck comes in @ Cd 0.30,with mirrors,then it would be around Cd 0.29 without.
It has none of the architecture of a higher drag form.All the relevant information is in Hucho's text.
AeroStealth had Cd 0.305 with his F-150 back in 2014.It's not that hard to do.
This is all computer simulations starting with a .35 pickup (which would be the current best) and they get down to .27 with the best aerocap. Pretty promising. I do think the Cybertruck needs to lose the massive fender flairs to get it.
