I looked at 27-vehicles which either shared similar L/h ratios,or similar aft-body-to-total body length ratio.The 27-vehicle sample had an average Cd 0.231,with a high of Cd 0.44,and a low of Cd 0.137.
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.
