Formula One (F1) cars can attain very high cornering speeds thanks to the generation of large amounts of aerodynamic downforce. They are the fastest road course racing cars in the world. Formula One cars can achieve speeds of up to approximately 375 km/h (233 mph). Formula 1 car can change gear 50 times faster than the blink of an eye. The cars are capable of lateral acceleration in excess of six g in corners. The performance of the cars is very dependent on electronics – although traction control and other driving aids have been banned since 2008 – and on aerodynamics, suspension, and tyres. The formula has radically evolved and changed through the history of the sport. F1 car is a product of prototypes and in a season can have thousands of updates. This makes CFD prototyping extremely important. This work deals with CFD of F1 cars. CFX simulation files of F1 CFD are also attached.
