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

I'm considering buying an Audi A5 and I noticed a feature called sport differential. What does this feature do and how does it benefit the vehicle's performance?

The sport differential is an electronically controlled torque vectoring system. It distributes power between the rear wheels to enhance handling and stability during corners.

In simple terms, the sport differential acts as a limited-slip differential but can also actively distribute torque between the rear wheels. This helps improve traction and agility, making the vehicle more responsive and stable.

Having a sport differential in the Audi A5 results in better cornering and less understeer. It allows for more power to be sent to the outside rear wheel, giving the car a more agile and dynamic driving experience.
