1,What is rear diffuser？
Rear diffusers were commonly used in F1 racing cars earlier, and now they are also used in some performance cars and even civilian cars. As an important part of the F1 car's aerodynamic package, the diffuser is mounted on the bottom of the car, so that the airflow pressure in the upper part of the car is greater than the airflow pressure at the bottom, thereby forming an air pressure difference, causing the car to generate a pressure toward the ground, which is the so-called Increase downforce so that racing tires have good grip.
2,Why do family cars need to install rear diffuser?
In addition to aerodynamic advantages, a rear diffuser can also add sportiness and visual appeal to a vehicle, making it the first choice for many car lovers today.
Secondly, a rear diffuser can generate more powerful downforce. Installing a rear diffuser on a family car can also improve the vehicle's high-speed stability and performance. It can quickly extract the airflow from the bottom of the car, thereby forming a low-pressure area under the car, while a high-pressure area is formed on the roof. district. This pressure difference between the high-pressure area and the low-pressure area will cause the vehicle body to form a downward force, enhancing the grip between the vehicle and the road surface and making the vehicle drive more stably.
In addition, the rear diffuser can be integrated into the bumper to help reduce vehicle weight. On some high-performance cars, exaggerated diffusers not only enhance the appearance of the vehicle, but also reduce the ground clearance, allowing the vehicle to retract the diffuser when passing on steeper roads, increasing the vehicle's departure angle and reducing The contact between the chassis and the ground.
Although the diffuser does not create additional aerodynamic drag, it does require a very smooth road surface to achieve consistent and stable downforce. When the diffuser is not working, the chassis is flatter, which can reduce unnecessary air resistance and thus reduce fuel consumption
