Open wheel racing is a type of motorsport where cars have exposed wheels, meaning the tires are not covered by bodywork. This design allows for better aerodynamics and handling, making the cars faster and more agile on the track. Popular series include Formula 1, IndyCar, and Formula E, each featuring unique cars and regulations. In open wheel racing, drivers compete on various circuits, including road courses and ovals. The races often emphasize speed, precision, and strategy, with teams working to optimize car performance. Safety measures, such as the halo device, are also crucial to protect drivers during high-speed events.
