How does the Audi A7's sport differential system work?

I've heard great things about the sport differential in the Audi A7, but I'm not sure exactly how it operates. Can someone explain it to me?

The Audi A7's sport differential system uses clutches and an electrohydraulic pressure valve to distribute torque between the rear wheels, giving you better handling and control while taking turns. Just be careful not to oversteer!

As for technology, the Audi A7's sport differential adjusts the distribution of torque between the wheels to optimize agility by working together with the quattro all-wheel drive system. No more worrying about losing traction on those tight curves!
