What are the most notable features of the Audi A8's all-wheel drive system?

I am looking to purchase an Audi A8 and am curious about the capabilities of its all-wheel drive system. Can it handle various driving conditions and what sets it apart from other AWD systems in the market?

Audi's Quattro all-wheel drive system boasts an impressive torque distribution of 40:60 between the front and rear axles, providing optimal traction and stability in all types of terrain and weather conditions.

The A8's all-wheel drive system also features a self-locking center differential, allowing it to send up to 70% of the engine's power to the front wheels or 80% to the rear wheels depending on the driving situation.
