How is the Quattro system different in the Audi A6 compared to other models?

I am curious about the Quattro system in the Audi A6 and how it differs from other Audi models. I've heard it is unique to this model but I would like to know what makes it stand out.

The Quattro system in the Audi A6 uses a self-locking center differential, which allows for better power transfer between the front and rear axles. This means better handling and traction in all types of road conditions.

Compared to other Audi models, the Quattro system in the Audi A6 is optimized for performance and efficiency. It is always active and utilizes sensors to constantly monitor driving conditions and distribute power accordingly.

The Quattro system in the Audi A6 also includes an electronic torque vectoring function, which can distribute power to individual wheels for even better handling and cornering abilities.
