Which is More Advanced: Variable Suspension or Air Suspension?

[Valerie]

Here is a related introduction to variable suspension and air suspension: 1. Variable Suspension Variable suspension refers to a system that can manually or automatically adjust the height or stiffness of the suspension to meet the driving needs on different road surfaces. Suspension is a factor of great concern to consumers as it directly affects the comfort and handling of the vehicle. However, with today's technology, ordinary spring shock absorbers can hardly achieve both. In the pursuit of perfection in the automotive field, the variable suspension system was born. The function of the variable suspension is to manually or automatically change the height/stiffness of the suspension to adapt to different road conditions. 2. Air Suspension: A high-quality SUV must have the comfort of a sedan while maintaining the off-road capability of an SUV. The air suspension system is the best choice to achieve this goal. Based on different road conditions and signals from distance sensors, the vehicle's computer will determine changes in the vehicle's height and then control the air compressor and exhaust valves to automatically compress or extend the springs, thereby reducing or increasing the ground clearance of the chassis to enhance high-speed stability or off-road capability on complex terrains.

I've driven many cars and feel that air suspension is more advanced than variable suspension. Technically, air suspension uses airbags to inflate and deflate, adjusting the vehicle's height and stiffness, allowing it to automatically adapt to different road conditions, such as providing a smoother ride over speed bumps or during cornering. High-end cars like Mercedes-Benz use it to enhance comfort. In contrast, variable suspension relies on electromagnetic or hydraulic systems for rapid adjustments, offering quick responses but lacking the intelligence and refinement of air suspension. Air suspension can also optimize vehicle aerodynamics, reducing drag and improving fuel efficiency, making it particularly cutting-edge in luxury models. However, its structure is more complex, involving components like compressors, resulting in higher costs. Overall, air suspension delivers superior handling and ride quality, undoubtedly making it the more advanced choice.
