This paper explores using a spoiler and wing to enhance driving at high speeds. This investigation utilizes both a shark-fin spoiler and a fixed geometry wing. Properly designed wings can mitigate tire traction issues in sports cars, while shark-fin spoilers provide further improvements. Aerodynamic devices have the potential to influence the design of sports cars in the future significantly. This work is computational, and the mathematical formulation rests on the continuity and momentum equations for unsteady incompressible flows. To accurately account for turbulence, we utilize the kOmegaSSt model, which employs two equations: one for turbulent kinetic energy and another for specific turbulence dissipation rate. The investigation results show that adding aerodynamic devices to a car can significantly impact its lift and drag coefficients. The drag coefficient increases with adding a shark-fin spoiler, flat wing, or both, while the lift coefficient becomes negative, providing downforce and improving tire traction. The vortical structure of the flow field behind the car becomes more complex with the addition of devices, leading to increased drag force. While engine power and traction are crucial for racing cars, everyday driving requires minimizing drag and fuel consumption. The study provides valuable insights into cars' aerodynamics with a shark-fin spoiler and a flat wing.
