What is Audi A7's quattro system and how does it improve the car's performance?

I'm interested in purchasing an Audi A7, but I'm wondering how the quattro system works and if it's worth the extra cost. Can anyone provide some insight into this feature?

The quattro system is Audi's all-wheel drive system that distributes power to all four wheels for improved traction and handling. In my experience, it definitely improves the car's performance, especially in inclement weather. Definitely worth the extra cost in my opinion!

I've driven both an Audi A7 with the quattro system and one without, and I can definitely feel the difference in handling and control. It's especially helpful in tight corners and on slippery roads. Definitely worth considering if you're looking for a high-performance vehicle.
