What is the difference between Audi's quattro and quattro S Sport differential systems?

I am considering purchasing an Audi, but I am unsure about the different quattro systems they offer. Can someone explain the difference between quattro and quattro S Sport?

The quattro system is Audi's all-wheel drive system, providing enhanced traction and stability on the road. The quattro S Sport system is a performance upgrade, specifically designed for high-performance driving. It offers an electronically controlled sport differential for improved handling and agility.

The difference between quattro and quattro S Sport lies in their intended purposes. The quattro system is ideal for everyday driving, while the quattro S Sport is geared towards enhancing performance and agility for driving enthusiasts.

Quattro and quattro S Sport both utilize torque vectoring technology to distribute power to individual wheels. However, the quattro S Sport offers a more dynamic and customizable driving experience, making it the preferred choice for those seeking a more engaging driving experience.
