What is Quattro permanent all-wheel drive?

I've heard that Audi has a unique all-wheel drive system called Quattro, but I'm not sure how it works and why it's different from other AWD systems. Can someone explain it to me?

Quattro permanent all-wheel drive is an innovative system developed by Audi that distributes power to all four wheels of the vehicle for better traction and control. Unlike traditional AWD systems that only engage when there is slip, Quattro provides constant power distribution for improved handling and stability in all driving conditions.

Think of Quattro as a brain that constantly communicates with each wheel to adjust power distribution for optimal traction and performance. This means you can confidently drive in snow, rain, or off-road without worrying about losing control.

In simple terms, Quattro improves your Audi's grip and handling on the road by sending power to the wheels with the most traction. This reduces understeer, oversteer, and wheel spinning, resulting in a safer and more enjoyable driving experience.
