In this video, we analyzed the design changes on the Tesla Cybertruck since the first concept was launched. Earlier, we had used a public 3D model off the internet for a "quick & dirty" CFD analysis. However flawed that approach was, it did highlight both the pros and cons:
The base profile allows for very good pressure recovery and thus low drag
The sharp edges need careful execution to avoid excessive flow separation & drag (and noise)
In this video, we used our old analysis and compared it to the design updates we spotted:
Air deflectors ahead of the front wheels
Rounded front bumper
Increased gap between upper & lower bumper
Flush headlights
Limited offset between roof and side windows
Windscreen wiper design

The AirShaper videos cover the basics of aerodynamics (aerodynamic drag, drag & lift coefficients, boundary layer theory, flow separation, reynolds number...), simulation aspects (computational fluid dynamics, CFD meshing, ...) and aerodynamic testing (wind tunnel testing, flow visualization, ...).
We then use those basics to explain the aerodynamics of (race) cars (aerodynamic efficiency of electric vehicles, aerodynamic drag, downforce, aero maps, formula one aerodynamics, ...), drones and airplanes (propellers, airfoils, electric aviation, eVTOLS, ...), motorcycles (wind buffeting, motogp aerodynamics, ...) and more!
