What does the Audi A5's all-wheel drive system do?

I'm considering purchasing an Audi A5, but I'm not sure what the all-wheel drive system does. Can you explain its function?

The all-wheel drive system in the Audi A5 constantly monitors and adjusts power distribution between the front and rear wheels to optimize traction and handling. This can be especially useful in inclement weather or when navigating uneven terrain.

Having all-wheel drive in a vehicle like the Audi A5 can provide a more responsive and stable driving experience, especially in tight turns and high-speed maneuvers.

If you live in an area with harsh winters, the all-wheel drive system in the Audi A5 can greatly improve your ability to safely navigate through snow, ice, and other challenging road conditions.
