The IVD is the anti-buoque system and the stabilization system. In Focus 2, the system works fairly rough, so it is necessary to remember it, as it is going to accelerate dramatically. If the wheel grip is not very good (sand on the pavement, puddle, dirt), the system will dramatically reduce the traction. The stabilization system avoids skidding and subsequent "waving" of the vehicle on the road. It should be borne in mind that the stabilization system does not cope well with the understeer of the front axle characteristic of the front-wheel-drive vehicles.
