What Does Vehicle Suspension Stiffness Adjustment Mean?
2 Answers
Vehicle suspension stiffness adjustment refers to the ability to manually adjust the softness or firmness of a car's suspension. However, with advancements in technology, the operational state of a car's suspension can now be adjusted automatically. The suspension system used in vehicles affects both comfort and handling. Suspension stiffness adjustment can be either manual or automatic. During driving, the driver can adjust the suspension's stiffness via buttons inside the car. At high speeds, the suspension can become firmer to enhance the vehicle's stability. When driving on bumpy roads, the suspension softens to filter out minor vibrations, thereby improving comfort. During high-speed cornering, the shock absorber's resistance automatically increases to reduce body roll.
I've been driving for 20 years, and suspension stiffness adjustment refers to the system in the car that can adjust the softness or hardness of the springs or shock absorbers according to road conditions or driving needs. For example, on bumpy city roads, I set it softer so the rear seats aren’t as shaky, making my family more comfortable; when taking sharp turns on highways, I stiffen it for better stability without body roll, reducing fatigue on long drives. This feature usually has buttons or screen options on the center console, with modes like Comfort, Sport, or Auto. On rainy slippery roads, a soft suspension absorbs vibrations to prevent skidding, while a stiff suspension provides more grip on mountain roads. However, don’t modify the factory system recklessly—it could void the warranty or even compromise safety. It’s best to consult professionals for regular maintenance.
