Which is more effective, KDSS or chassis lifting?
2 Answers
KDSS and chassis lifting are two completely different systems, each with its own advantages. KDSS controls the stabilizer bar to reduce body roll during turns and increase suspension travel during off-road driving. Chassis lifting is only available on top-tier vehicles equipped with air suspension and is used to improve the vehicle's ground clearance. Below are detailed introductions about KDSS: 1. Introduction One: KDSS stands for Kinetic Dynamic Suspension System, which is called an electronically controlled dynamic adjustment suspension system in Chinese. This system combines two seemingly contradictory performance characteristics. During off-road driving, it allows the suspension to extend freely, ensuring sufficient wheel travel for tire contact with the ground, thereby enhancing stability and off-road capability. During highway driving, it restricts suspension extension and twists the stabilizer bar to reduce roll during turns, improving handling and comfort. 2. Introduction Two: Both the front and rear stabilizer bars have independent hydraulic cylinders for vertical motion control, connected by a hydraulic system. Each stabilizer bar's hydraulic cylinder is divided into upper and lower chambers. The front upper and lower hydraulic chambers are connected to the rear upper and lower hydraulic chambers via their respective hydraulic lines. Each hydraulic line contains an accumulator. KDSS controls a set of valves connected to the accumulators in the hydraulic lines to maintain each stabilizer bar in its optimal state.
I've driven quite a few vehicles equipped with KDSS and adjustable suspension, and I feel these two features each have their own merits. KDSS primarily enhances handling stability by automatically balancing the front and rear suspension during turns to prevent excessive body roll, which is particularly noticeable on winding mountain roads or during high-speed cornering. The adjustable suspension, on the other hand, adapts to different terrains by altering the ground clearance—raising it for off-road conditions to prevent scraping the undercarriage and lowering it for highway driving to improve fuel efficiency. In terms of scope of effect, KDSS influences the fundamental support of the vehicle's dynamic performance, while the adjustable suspension addresses the challenge of ground clearance. For average drivers, the changes brought by the adjustable suspension might feel more immediately noticeable in daily use, but the stability provided by KDSS is more enduring. My recommendation is to choose based on road conditions: opt for adjustable suspension if you frequently traverse rough terrain, and go for KDSS if you mostly drive on highways or mountain roads.
