How does the Audi A3's quattro all-wheel drive system provide better handling in different road conditions?

I've heard that the Audi A3 has a quattro all-wheel drive system, but I'm not sure how it works. Can someone explain how it works and what makes it different from other all-wheel drive systems?

The quattro all-wheel drive system in the Audi A3 uses torque vectoring to continuously distribute power to the wheels with the most grip, allowing for better traction and handling in various weather and road conditions.

Unlike other all-wheel drive systems that only react when a loss of traction is detected, the Audi A3's quattro system proactively distributes power to the wheels for better stability and control, making it an ideal choice for snowy or wet roads.

With the quattro all-wheel drive system in the Audi A3, power is sent to all four wheels, providing better grip and minimizing understeer and oversteer, resulting in a smoother and safer driving experience.
