How does the Audi A7's Quattro all-wheel drive system provide better handling and traction?

I've heard that the Audi A7 has a Quattro all-wheel drive system, but I'm not sure how it actually improves my driving experience. Can someone explain the technical details?

The Quattro all-wheel drive system in the Audi A7 uses a central differential to distribute power to all four wheels, providing better grip and traction in all driving conditions.

With Quattro all-wheel drive, the Audi A7 can send up to 85% of its power to the rear wheels, helping to enhance handling and cornering.

In snowy or slippery conditions, the Quattro all-wheel drive system in the Audi A7 can distribute power to the wheels with the most traction, helping to maintain control and stability.
