What is the purpose of the differential in a vehicle?

The purpose of the differential in a vehicle is to allow for wheel rotation at different speeds. This mechanism is crucial because when a vehicle turns, the outer wheels travel a longer distance than the inner wheels. The differential enables each wheel to rotate at its appropriate speed, which contributes to better handling and stability during turns. Additionally, it helps in distributing power from the engine to the wheels more effectively, improving traction and overall driving performance.

While enhancing braking performance relates more to the brake system, managing steering is the function of the steering mechanism itself. Cooling the engine is the role of the engine cooling system. Thus, the primary function of the differential focuses on enabling the independent motion of wheels, particularly during turns, making it essential for the vehicle's maneuverability.
