What is the primary function of the car's suspension system?

The primary function of the car's suspension system is to support the vehicle's weight. This system is designed to maintain the vehicle's stability and ensure that it stays balanced, even when driving over uneven surfaces. By supporting the weight of the vehicle, the suspension allows for proper handling and comfort, ensuring that the car can navigate various terrains without excessive bouncing or instability.

While the suspension system does contribute to other aspects of vehicle performance—like controlling tire movement or providing a smoother ride—it fundamentally acts as the foundation that supports the weight of the car and its occupants. This is critical for safety and performance, as a well-functioning suspension system ensures that all four tires maintain contact with the road, which is essential for good traction and control.
