What is the Quattro system in the Audi A5 and how does it affect the car's handling?

I've heard that the Audi A5 comes with Quattro all-wheel drive, but I'm not sure exactly what it does. Can someone explain its function and how it impacts the car's performance?

Quattro is Audi's brand of all-wheel drive system, which distributes power between the front and rear wheels for better handling and grip on all types of road surfaces.

The Quattro system uses a central differential to split the power between the front and rear wheels, providing better traction and stability in corners or slippery conditions.

With Quattro, the A5 can maintain a balanced weight distribution and improved grip on the road, making it more responsive and enjoyable to drive.
