Why does the Audi A5 have a Quattro system and what benefits does it provide?

I'm a bit confused about the Quattro system in the Audi A5. Can you explain what it is and how it works?

The Quattro system in the Audi A5 is a unique all-wheel drive system that distributes power to all four wheels. This provides improved traction and stability, especially in harsh weather conditions. It also enhances the overall handling and performance of the car.

The Quattro system in the Audi A5 uses a center differential to distribute power between the front and rear axles, and can send power to individual wheels for maximum grip. This allows for better control and responsiveness while driving on varying terrain.
