Following the Cybertruck CFD controversy I spent over 8-weeks creating a rebuttal,illustrating why it might be impossible for Cybertruck to generate Cd 0.48,as some advocate,and a lot had to do with Tesla's active suspension.With 8-inches (203.2mm) of front and rear suspension travel,Cybertruck is provided with the potential to 'tune' the aerodynamics on-the-fly,using the entire underbody as a diffuser,as Ford Motor Company did with their Cd 0.152,1983 Probe-IV concept car,and probably their Cd 0.137,1985,Probe-V concept.
Somehow,this capability was never explored in the numerical simulations,while Hucho has provided empirical evidence demonstrating that attached,longitudinal vortices which would be necessary to explain such a high drag cannot exist in a potentially inclined body as Cybertruck possesses.
I'm in total agreement as to the significance of this technology.Great video!
