Launched on the 207, the SSP system, in certain braking conditions, permits coupling between the ESP function and the car's power assisted steering. Communication between these two devices improves the vehicle's stability and stopping distance in the straights, during braking on surfaces with different grip between the right-hand wheels and the left-hand wheels (for example, with "high adhesion" asphalting on one side and "low adhesion" on the other side, such as ice, mud, wet grass, etc.).

In normal weather, the ESP function will recognise the asymmetry of the surfacing and limit braking on the "high adhesion" part. This programming preserves the car's stability, but does not optimise its braking performance. In this situation, the SSP will make it possible to brake from the outset more on the adhesive part of the road and, anticipating vehicle instability, will apply torque in the steering system to help the driver achieve an optimum angle with the steering wheel. This torque is sent less than 100 ms after the start of braking and the recommended angle can be up to 80 degrees.

This is not "automatic counter-steering", because the driver can choose not to obey the steering wheel set point value, in which case the braking system returns to a conventional strategy giving priority to stability. Ultimately, this system results in a gain in stopping distance ranging between 4% and 10% depending on the conditions, while ensuring stability of the vehicle. It is not yet very widely used, and this is the first time it has been applied on a vehicle of this segment.
