Which part of the vehicle is primarily responsible for handling steering and suspension movements?

The suspension system is specifically designed to handle steering and suspension movements within a vehicle. This system absorbs shocks from the road, maintains tire contact, and enables controlled handling when the vehicle is in motion. It consists of various components such as springs, shock absorbers, and linkages, all of which work together to provide stability and comfort during driving.

By effectively managing the combination of vertical and lateral forces acting on the vehicle, the suspension system ensures that the driver has optimal control during steering maneuvers and that the ride remains smooth over uneven surfaces. The suspension system directly influences vehicle alignment and the overall dynamics of how the car responds to steering inputs, making it a critical component for both performance and safety.

While the chassis is the framework that supports the vehicle's body and components, and the body comprises the outer shell and structure of the vehicle, neither directly manages the dynamics of steering or absorbs road input like the suspension system does. The transmission, on the other hand, is responsible for transferring power from the engine to the wheels, which is unrelated to the handling of steering and suspension movements. Thus, the suspension system is indeed the key part of a vehicle that manages these functions effectively.
