My project aims to help improve aerodynamic efficiency for electric cars. Following up on existing research and integrating aerodynamic efficiency with high downforce using design changes as well as working upon the half car body. The final goal is to end up with a electric car design that has low drag and high downforce both which are important factors for high performance road cars. Using computational fluid dynamic (software) to analyze the performance of my final design to evaluate the parameters such as drag and downforce, which will help me create a better design. My research question is How can the aerodynamic design of electric vehicles be optimized to reduce drag at high speeds while maintaining acceleration, as evaluated through simulations? The study will help benifit consumers as well as manufacaturers ad the enviroment by helping increasing efficiency, range and speed of electric cars.
