At YouTube,under 'Cybertruck aerodynamics',Boats and Engines was kind enough to share an introductory 2D and 3D CFD analysis of a Cybertruck model.He wasn't able to get the virtual model into ground reflection,which he admits will affect the measured values,and Cd varies with velocity,between 40-mph,and 88-mph,which would not occur in the real world.Also,fine body details could not be analyzed,which would affect drag,however the viewer does get a pick-and-shovel look at the Tesla's performance.
Boats and Engines reports that analysis of other vehicles returned Cd values higher than officially reported,and appeared to be impressed by Cybertruck's trending downwards towards Cd 0.30 @ 88-mph.Evidently,many passenger car shapes he tested could not produce drag coefficients represented by Cybertruck.And no pickups analyzed could approach it.
The video is only 5:52-minutes in length and packs in a lot of information in the limited time frame.
