Which of the following is NOT a benefit of a limited-slip differential?

A limited-slip differential (LSD) is designed to improve performance in various driving conditions by allowing for some difference in wheel speed while also distributing power effectively. The benefits of improved traction, less power lost during turns, and better handling on slippery surfaces are all directly related to the LSD's ability to transfer torque to the wheel with better grip.

Improved traction occurs because the LSD can send more torque to the wheel that has more grip during acceleration or when cornering, reducing the chances of wheel spin. Less power loss during turns happens because the LSD limits the amount of slip between the wheels, allowing for a more efficient distribution of power. Better handling on slippery surfaces is essential since the LSD helps maintain control by ensuring that power is still effectively transferred even in conditions where traction is limited.

On the other hand, while a limited-slip differential can enhance performance characteristics overall, it does not inherently increase fuel efficiency. Fuel efficiency is primarily affected by factors such as engine efficiency, vehicle weight, aerodynamics, and driving habits. Therefore, although an LSD can improve driving dynamics, it does not directly contribute to increased fuel efficiency in the same way that other vehicle systems can.
