What is the difference between quattro and all-wheel drive on Audi vehicles?

I have heard Audi use the term quattro when talking about their all-wheel drive system, but I'm not sure what sets it apart from other all-wheel drive systems. Can someone explain the difference?

Quattro is Audi's branded all-wheel drive system that is known for its superior performance and handling. Unlike conventional all-wheel drive systems, quattro uses a self-locking center differential, which continuously distributes power between the front and rear axles. This means that power is always being delivered to the wheels with the most traction, providing enhanced stability and control.

One of the biggest differences between quattro and other all-wheel drive systems is its ability to anticipate and respond to changing driving conditions. Quattro uses sensors to monitor wheel speed, acceleration, and steering to adjust the power delivered to each wheel, ensuring optimal traction and grip on any surface.

Compared to traditional all-wheel drive systems, quattro is also known for its faster response time and ability to handle more extreme driving situations. This is thanks to its torque vectoring technology, which can send power to individual wheels as needed to help with cornering and maintaining control on slippery roads.
