What is the function of shock absorbers in a vehicle?

Shock absorbers play a crucial role in a vehicle's suspension system by absorbing the energy from bumps and irregularities in the road surface. This absorption helps to stabilize the vehicle, preventing excessive bouncing and ensuring that the tires maintain contact with the road. By doing so, shock absorbers enhance ride comfort and contribute to better handling and safety. They control the rate at which the suspension springs compress and rebound, which ultimately allows for more predictable vehicle dynamics during various driving conditions.

The other options do not accurately describe the primary function of shock absorbers. Providing power to the wheels is the role of the drivetrain; improving fuel efficiency is typically achieved through vehicle design and engine management rather than through suspension components; and enhancing engine performance relates to the engine itself, not the suspension or shock absorption system.
