On its part, Tesla said nothing about the car’s aerodynamics, it announced no drag coefficient. Sure, the car looks like a metal toolbox, but keep in mind it has been drawn by an experienced team, and that most likely means it will deliver on its makers’ promises.
Given Tesla’s silence on the subject, an aerospace engineer by the name of Justin Martin took it upon himself to find out exactly how air behaves when it encounters the stainless steel monster. So he ran a simulation, and sent the results to Electrek.
Keep in mind that Martin did not have access to actual car renderings and files, and his simulation is based only on the study of Cybertruck official photos, transposed into a computational fluid dynamics computer software. That means the results are neither official, nor entirely reliable.
Yet, data seems to show all the concerns raised about Cybertruck’s capabilities were unfounded. It seems the airflow sticks to the car, even after hitting the pointy edge of the car’s roof, and flows around it without major issues.
What’s more important, no serious vortexes are created (except, perhaps, at the very rear), nor does the air hit the car as a stone wall.
Martin did not say anything about a drag coefficient value, as there are to many unknowns in the simulation he ran.
