The suspension system is a key component connecting the wheels and the vehicle body, primarily responsible for cushioning road impacts, maintaining body stability, and enhancing handling performance. Double-wishbone and multi-link suspensions are more commonly found in mid-to-high-end models; by utilizing multiple links to precisely control wheel trajectories, they significantly improve handling and comfort, though at higher manufacturing costs. Non-independent suspensions such as torsion beam suspensions, owing to their compact structure and low cost, are frequently employed in the rear wheels of economy cars, albeit with slightly inferior comfort. Additionally, advanced systems like air suspension and electromagnetic suspension can adjust suspension characteristics in real time by regulating air pressure or electric current, and are predominantly used in luxury models to balance dynamic performance and ride quality. When selecting a vehicle, consumers can make choices based on their budget and requirements; for instance, family cars typically prioritize a combination of MacPherson struts and torsion beam suspensions, while performance or luxury vehicles often favor multi-link or air suspensions.
