How does the Audi A7's Quattro all-wheel drive system improve handling in different weather conditions?

I've always heard that Quattro is a top-of-the-line all-wheel drive system, but I don't fully understand its capabilities. How does it work and what kind of benefits does it offer for driving in snow, rain, and other conditions?

Quattro is Audi's signature all-wheel drive system, featuring a self-locking center differential and advanced sensors that continuously monitor road conditions. This enables it to proactively shift power to the wheels with the most traction, so you can maintain control and stability even in slippery or uneven terrain.

I've driven the A7 through heavy snow and it handles like a dream thanks to Quattro. It's not just about grip and traction - the system also helps with braking and cornering, making it a key feature for all types of weather and terrain.
