How does the Audi A1's Quattro system improve handling in snowy conditions?

I'm planning on purchasing a new Audi A1 but live in an area with harsh and snowy winters. I've heard that the A1 comes with a Quattro system, but I'm not sure exactly how it works and if it's worth the extra cost. Can anyone explain how the Quattro system works and how it improves handling in snowy conditions?

The Quattro system uses a combination of sensors and electronic controls to distribute power to all four wheels, providing better traction and control in slippery conditions. It's definitely worth the extra cost for improved safety and performance in snowy conditions.
