What does the M8's xDrive system do?

I'm interested in purchasing a BMW M8 and I keep seeing information about its xDrive system. What exactly does this system do and how does it affect the car's performance and handling?

The M8's xDrive is BMW's intelligent all-wheel drive system. It continuously monitors the road conditions and distributes power between the front and rear axles to provide optimal traction and control. This results in improved handling, especially in wet or slippery conditions.

The xDrive system in the M8 is also paired with an Active M Differential, which constantly adjusts the distribution of power between the rear wheels. This allows for better cornering and stability when taking sharp turns or accelerating out of corners.
