How does the torque vectoring system work in the Audi A7?

I've heard that Audi A7's have a torque vectoring system, but I'm not sure how it really works. Can someone explain it to me in more detail?

The torque vectoring system in the Audi A7 uses the car's anti-lock braking system to selectively apply braking pressure to the wheels in order to improve handling and stability in turns. It essentially helps to reduce understeer and oversteer.

To put it more simply, the torque vectoring system in the Audi A7 helps distribute power to the wheels that need it most during cornering. This results in better traction and control.
