MSP (Maserati Stability Program) is an electronic stability control system installed on Maserati cars. It stabilises the car body when manoeuvring and driving on slippery roads.
How MSP works
The vehicle’s actual path is estimated based on the wheel speed, yaw rate, and lateral and longitudinal acceleration, as well as the brake system pressure. The intended direction of travel is determined by the steering wheel angle and brake pedal position. If the actual values don’t match the driver’s intentions, individual wheels are slowed down and the engine torque is limited. This helps to restore the trajectory and traction.
Unlike in the normal mode, in the “Sport” mode the system intervenes less in driving. Only the brakes are used to stabilise the car body. This provides more opportunity to perform manoeuvres such as controlled skidding. When driving on loose surfaces, it is advisable to deactivate MSP by pressing the “A” button mounted on the centre console.
