What is the difference between Audi A8's 4MATIC and quattro four-wheel drive systems?

I am trying to decide between purchasing an Audi A8 with 4MATIC or quattro four-wheel drive. Can someone explain the differences between these two systems and which one would be better for driving in various road conditions?

The Audi A8's 4MATIC system is a rear-wheel biased system that uses a center differential to distribute power to the front and rear wheels. On the other hand, the quattro system uses a center differential and electronic torque vectoring to distribute power to each wheel for optimal performance and handling in any condition.

While both systems offer better traction and control in slippery conditions, the quattro system takes it a step further with its ability to send power to specific wheels based on grip and cornering. This makes it a great choice for drivers who want to push their A8 to the limit on winding roads or in inclement weather.

For everyday driving, both systems will provide a smooth and stable ride. However, if you live in an area with extreme weather conditions, the quattro system may be the better option for its enhanced handling and control.
