Why is the Audi A7's quattro system different from other Audi models?

I've heard that the Audi A7 has a unique quattro system compared to other Audi models, can you explain why?

The Audi A7 uses a mechanical center differential instead of the standard electronic differential, which allows for better power distribution and handling. So, you'll experience a smoother and more responsive driving experience compared to other Audi models.

The Audi A7 also has a unique sport differential, which actively distributes power between the rear wheels for improved handling and cornering. You'll notice the difference when taking sharp turns or driving on winding roads.

In addition, the quattro system in the Audi A7 is optimized for performance and efficiency. It constantly monitors road conditions and adjusts power distribution accordingly, providing improved traction and fuel efficiency.
