What is the purpose of the sport differential in the Audi A5?

I am considering purchasing an Audi A5, but I'm not sure what the sport differential does. Can someone explain it to me in simple terms?

The sport differential in the Audi A5 is a mechanical rear axle differential that can actively distribute torque between the rear wheels. This allows for improved handling and stability, especially in combination with other driver assist systems.

The sport differential in the Audi A5 adjusts the distribution of power between the rear wheels to improve handling and reduce understeering. It also works with the car's stability and traction control systems to optimize performance.
