How does the Audi A4's quattro all-wheel drive system improve performance on slick roads?

I'm planning on purchasing an Audi A4, but I live in an area that gets a lot of snow and ice during the winter. I've heard that the A4 comes with a quattro all-wheel drive system, but I'm not sure exactly how it works and if it will make a difference in my daily driving. Can someone explain how the quattro system improves performance on slick roads?

The Audi A4's quattro all-wheel drive system is designed to improve traction and handling on slick roads by distributing power to all four wheels, rather than just the front or rear wheels. This helps to maintain better control and stability in slippery conditions, reducing the risk of sliding or losing control of the vehicle.

One of the main advantages of the Audi A4's quattro all-wheel drive system is its ability to quickly adjust power distribution to individual wheels, depending on which ones have the most grip. This helps to prevent wheel slippage and allows the vehicle to maintain traction and stability on slick roads.
