Why does the Audi A7 have a Quattro all-wheel drive system?

I've heard that the Audi A7 has a Quattro all-wheel drive system, but I'm not sure why that's important or what makes it different from other systems. Can you explain?

The Quattro all-wheel drive system used in the Audi A7 provides superior traction and handling, especially in challenging driving conditions like snow or rain. It distributes power between the front and rear axles to optimize grip, resulting in improved performance and safety. My advice would be to test it out on a variety of roads to experience the difference for yourself.

A unique feature of the Quattro all-wheel drive system in the Audi A7 is its self-locking center differential. This electronically-controlled differential continuously monitors and adjusts the torque distribution between the front and rear axles, allowing for precise and efficient power distribution. I recommend taking a closer look at this feature when considering the A7.
