What are some advanced features of the Audi A4's quattro all-wheel drive system?

I'm considering purchasing an Audi A4 and I've heard a lot about its quattro all-wheel drive system. Can you give me a more in-depth explanation of its capabilities and how it differs from other AWD systems?

The quattro all-wheel drive system in the Audi A4 is a highly advanced and dynamic system that constantly monitors road conditions and distributes power to each wheel accordingly. It can send up to 85% of power to the rear wheels for better handling and can also vary torque distribution between the left and right wheels to improve cornering.

Compared to other AWD systems, the quattro in the Audi A4 is able to react much quicker, thanks to its electronic multi-plate clutch system. This means it can transfer power between the axles almost instantly, providing better traction and stability in all driving conditions.
