What is quattro Ultra Technology in the Audi A6?

I've heard about Audi's quattro Ultra Technology, but I'm not sure what it does or how it works. Can someone explain it to me?

Quattro Ultra Technology is Audi's all-wheel drive system that is designed to optimize efficiency and improve handling by automatically switching between front-wheel drive and all-wheel drive depending on road conditions and the driver's inputs. It utilizes an intelligent control unit to constantly monitor and adapt the power distribution between the front and rear axles.

Although quattro Ultra Technology may seem like a complicated system, the concept is simple - it allows for improved traction, stability, and agility by distributing power to the wheels with the most grip. This means better handling and control in all types of weather and road conditions.
