What are the differences between racing cars and ordinary cars?
1 Answers
Here are the main differences between racing cars and ordinary cars: 1. Tires: For common racing cars, the tires perform best when the temperature is around 100°C, providing maximum grip on the ground. Before participating in a race, the tires are preheated in a heater and then installed on the car. Only after completing a full lap do the tires reach their optimal state. Ordinary cars do not require this. 2. Seat belts: The seat belts in civilian cars are generally diagonal three-point type and come with a pre-tensioning device. Under normal driving conditions, they can be easily pulled to the driver's chest and abdomen to avoid discomfort. They only automatically tighten during emergency braking or severe body shaking to secure the occupant in the seat and prevent impact with the windshield. Racing cars have higher requirements; their seat belts are double-shoulder fixed with an additional strap across the waist and lack a pre-tensioning device. Racing seat belts also feature a quick-release mechanism. In case of an accident, pressing the square button on the chest will instantly release all the various straps wrapped around the body, allowing the driver to escape quickly. 3. Engine and fuel: Racing car engines require high RPM and power output. Therefore, these engines have very short piston strokes, large displacement, and small mass, which helps increase the engine's RPM and power. In contrast, ordinary car engines rarely operate at extremely high RPMs.
