How does the Audi A4's Quattro all-wheel drive system work and what are its advantages?

I've heard that the Audi A4 has a Quattro all-wheel drive system, but I'm not sure what that means or how it affects the car's performance. Can you explain it to me and why it's better than just front-wheel or rear-wheel drive?

The Quattro all-wheel drive system in the Audi A4 utilizes a center differential to distribute power between the front and rear axles. This allows for better traction and handling in all types of road conditions.

Compared to front-wheel or rear-wheel drive, the Quattro all-wheel drive system in the Audi A4 provides better stability and control, especially in adverse weather conditions like rain or snow.

With the Quattro all-wheel drive system, the Audi A4 is able to deliver power to all four wheels simultaneously, providing better acceleration and cornering abilities.
