What is the function of the differential in a vehicle?

The function of the differential in a vehicle is to enable the wheels to turn at different speeds while cornering. This is essential because, when a vehicle turns, the wheels on the outside of the turn must cover a greater distance than the wheels on the inside. The differential allows for this difference in wheel speed, which enhances traction, stability, and overall handling during turns.

Without a differential, both wheels would turn at the same speed, causing tires to skid or drag, particularly on tight corners. This would not only make driving more challenging but could also lead to unnecessary tire wear and reduced control over the vehicle. Consequently, the differential plays a crucial role in delivering a smooth and safe driving experience by compensating for the variation in wheel speed that occurs during cornering.
