How does the all-wheel drive system work on the Audi A4?

I've heard that the Audi A4 has an advanced all-wheel drive system. Can you explain how it works and how it differs from traditional AWD systems?

The Audi A4 uses a quattro all-wheel drive system, which constantly monitors and adjusts power distribution between the front and rear axles to optimize traction and handling in all conditions. This is different from traditional AWD systems which only engage when there is slippage.

The quattro all-wheel drive system on the Audi A4 utilizes a self-locking center differential that can send up to 85% of power to the rear wheels when needed, providing a more balanced and dynamic driving experience on any road surface.

In addition to the self-locking center differential, the quattro all-wheel drive system on the Audi A4 also has torque vectoring technology, which can distribute power between individual wheels for precise handling and stability while cornering.
