What is the technology behind Audi's quattro all-wheel drive system?

I'm looking to buy an Audi and I've heard a lot about their quattro all-wheel drive system. Can someone explain how it works and what makes it different from other AWD systems?

Audi's quattro all-wheel drive system uses a center differential to distribute power to all four wheels, providing improved traction and control on all road surfaces. Compared to other AWD systems, quattro offers a more balanced and dynamic driving experience, making it a great choice for performance-oriented vehicles.

One of the key features of Audi's quattro all-wheel drive system is its torque vectoring technology, which allows for individual power distribution to each wheel for better handling and cornering. This makes it an ideal option for driving in various weather and road conditions.

What sets Audi's quattro all-wheel drive system apart from others is its mechanical design, which uses a self-locking center differential instead of electronic controls. This results in quicker and more accurate power distribution, providing superior traction and control on both wet and dry roads.
