What does adjustable suspension stiffness mean?

[VonKing]

Adjustable suspension stiffness refers to the ability to manually adjust the softness or firmness of a car's suspension. With technological advancements, the operating state of the car's suspension can now be automatically adjusted. As automotive production technology continues to evolve, high-end car models now utilize variable suspension systems. The function of a variable suspension system is to manually or automatically change the height or stiffness of the suspension, thereby adapting to different road conditions and driving needs. During high-speed driving, the suspension can become firmer to enhance the stability of the car body; when traversing bumpy roads, the car's suspension will soften to filter out minor vibrations, thereby improving comfort; when taking sharp turns at high speeds, the shock absorber's resistance automatically increases to reduce body roll. Suspension stiffness adjustment can be done either manually or automatically. While driving, the driver can adjust the suspension stiffness via buttons inside the car. Another method involves the car adjusting the suspension stiffness based on driving speed or sensor data.
