Why does the 2021 Audi A4 have a sport differential and how does it improve performance?

I've noticed that the 2021 Audi A4 comes with a sport differential as an available feature. What is a sport differential and how does it work to enhance the vehicle's performance? Is it worth the extra cost for this feature?

The sport differential in the 2021 Audi A4 is a valuable feature for those seeking a dynamic driving experience. This system actively distributes torque between the rear wheels, allowing for more precise control and improved handling. It works by sending more power to the outside wheel when turning, reducing understeer and improving overall grip and agility.
