Hydractive suspension: its definition

The hydractive suspension system filters out road irregularities, as hydraulic suspensions once did.

The novelty is the electronic part connected to the system, which allows a more efficient and autonomous use of the process through some new sensors.

This old technology has been revived by manufacturers and allows the automatic adaptation of the vehicle’s height according to its speed and the condition of the road. Thus, the road holding is preserved and the comfort of the passengers is ensured.

The car can rise up to 20 mm if the speed is lower than 60 km/h without the driver having to do anything: the system is intelligent and makes decisions on its own after some quick calculations.

Good to know: don’t expect to be subjected to constant movement due to your hydractive suspensions. They are stabilized at a reference height to ensure full safety, and the height only changes between 10 and 60 km/h if needed. If the road is damaged but the vehicle’s speed is too high, nothing happens for safety reasons.

Characteristics of hydractive suspensions

How Does Hydractive Suspension Work


The hydractive suspensions combine hydraulic systems and electronic advances. Sensors are integrated into your vehicle to define before any action:

  • steering wheel angle;

  • vehicle speed;

  • the height of the car;

  • the condition of the pavement according to the variations.

If the right conditions are met, an electric motor starts up and activates a pump that will provide a sufficient flow of liquid to raise the car. The system is designed to cause as little sensation as possible to the driver and passengers. It acts silently.

Good to know: a revision of the system is recommended every 5 years or every 200,000 km.

Advantages and disadvantages of hydractive suspensions


Owning a vehicle equipped with a hydractive suspension means being assured of exceptional road holding and optimal comfort:

  • The car adapts itself to the condition of the road and frees your mind from certain worries: you are no longer afraid of damaging your vehicle.

  • The operation is smooth and silent: no more pitching and seasickness that the old models could make you feel.

  • The system is intelligent and checks your speed and the angle of your steering wheel before acting. All this is done in complete safety.


If the hydractive suspension system has many advantages, it still suffers from some failures: maintenance must be scrupulous! If the car owner is not careful, the system can quickly seize up, and repairs are very expensive.

Worse, if the hydraulic pressure runs out, the whole car won’t be able to run anymore!

Good to know: the dashboards are equipped with lights that warn you of the level. So you’ll never be caught off guard.
