The reason is again with the sideslip angle: The car without AHK develops
sideslip in a curve which is still present at the exit of the curve.

While doing so, the onset of oversteer is noticeable
in good time and the linear increase of the
sideslip angle means that the vehicle remains stable,» noted BMW's release.
The
sideslip angle has a negative impact on the steering response of a vehicle and the steering effort that is required to change direction: If a driver decides to change direction
in a curve while the vehicle is subject to oversteer and turns the steering wheel, because of the
sideslip angle the vehicle's longitudinal axis has to cross the current direction of motion first before the vehicle body actually changes direction.
In oversteer the sideslip angle amplifies itself ultimately ending in a spi
In oversteer the

in a spin.
Because of the smaller
sideslip angle
in curves the test vehicle equipped with AHK was more stable on corner exits allowing the driver to apply throttle much sooner and gaining higher speeds on the straights.
Minimizing the
sideslip does not only improve safety
in curves.
The key to improving the handling and stability
in high - speed maneuvers is minimizing the
sideslip angle.
Alternatively, the activation of the stability control system can be triggered by an excess of estimated
sideslip angle, corresponding to a potential vehicle oversteer situation
in comparison with the nominal conditions.
