AdvantagesofPSM
–Superiortractionandlane-holdingabilityinalldrivingsituations-evenonroadsurfaceswithvaryingfriction.
–Thesystemcompensatesforundesiredvehi-clereactions(Ferrariaeffect)whenthedriverreleasestheacceleratorpedalorbrakeson

–PSMactivelystabilizesthevehicleduringdynamicdrivingmaneuvers(e.g.rapidsteeringmovements,duringlanechangesoronalternatingcurves).
–Improvedbrakingstabilityincurvesandondifferentorvaryingroadsurfaces.
Readinessforoperation
