How does an independent rear suspension system differ from a dependent suspension system?

An independent rear suspension system is characterized by its ability to allow each wheel to move independently from the others. This means that when one wheel encounters a bump or dip in the road, it can move up or down without affecting the position of the other wheel. This independent movement enhances ride quality, improves traction by maintaining tire contact with the road, and provides better handling, particularly on uneven surfaces.

In contrast, a dependent suspension system connects the wheels together, meaning that if one wheel moves, it can influence the movement of the opposite wheel. This can lead to reduced ride comfort and handling, especially in situations where one wheel is on a rough surface while the other is on a smooth surface.

Understanding this distinction is critical for applications where ride comfort and handling performance are prioritized, such as in high-performance vehicles, off-road vehicles, or luxury cars. Therefore, the ability of each wheel to move independently is a significant advantage in modern vehicle design, which is precisely why this answer is correct.
