For the X3...

Performance Control.

The Performance Control distributes engine and braking control to the individual wheels when turning.

Because the outer wheels have to move a longer distance than the inner wheels when turning, the BMW Performance Control intervenes by means of engine output and controlled braking: The outer wheels get more power while the inner wheels get less, maximising traction on each of the wheels. This means that the vehicle practically turns itself, thus increasing driving safety and comfort.
Dynamic Performance Control (as in the X5 M), uses the torque vectoring diff.
