How does the Audi A4's AWD system enhance the car's handling?

I have read a lot about the Audi A4's advanced Quattro all-wheel drive system, but I am still unsure how it actually affects the car's performance. Can anyone explain how this system enhances the car's handling on various road conditions?

The Audi A4's Quattro all-wheel drive system uses a torque-vectoring differential to distribute power to the wheels with the most grip, providing better traction and control. Speaking from experience, it makes a big difference in wet or snowy conditions.

In addition to improved handling, the Quattro system also adds weight to the front end of the car, providing better balance and a more stable feel on the road. This can be especially beneficial in high-speed turns or corners.
