Evaluation and improvement of Tesla Cybertruck aerodynamic performance

In our fast-changing world with advanced technologies and enough mature attitudes toward the design of vehicles, automotive engineers are still working on how to model the car with parameters that meet the high requirements of the driver while keeping this vehicle within the legislation framework. However, both the requirements of the driver and the restrictions of the legislation framework are increasing significantly year by year. Then it is obvious that the great challenge behind the automotive manufacturers should be overcome. Following this, the desire to acknowledge how car manufacturers are dealing with this trend, urged us to explore the aerodynamic behavior of recent models on the market and forced us to implement changes to the vehicle. And the present thesis work focuses on the evaluation of the aerodynamic performance of the Tesla Cybertruck and its aerodynamic coefficients reduction in high speeds by installing add-on details. The first part of the work represents an overview of the fundamentals of aerodynamics, which will be continued with an overview of aerodynamic CFD simulation. The second part of the work includes the analysis of aerodynamic behavior by executing a CFD Simulation of Cybertruck like in real world conditions using the very powerful numerical software tool STAR CCM+ in order to identify problematic regions in an existing model. Finally, the installation of additional components was performed on an existing CAD model to further decrease the drag and lift coefficient.
