INNOVATION

4CONTROL CHASSIS

The 4Control chassis, co-developed by Renault and Renault Sport Technologies, reconciles driving pleasure, pinpoint handling and reinforced safety.

Cutting-edge technology 

4Control, how does it work?

A major technological innovation, the 4Control chassis was revealed at the 2007 Frankfurt Motor Show. Today, it is available on Laguna GT and Laguna Coupé.

 

4Control technology manages vehicle dynamics electronically. An electronic control unit (ECU) continually monitors speed, steering wheel angle and driving style, and, based on these parameters, transmits the right command for the rear wheel turning angle. Vehicle trajectory is thus modeled and corrected at every instant.

Incomparable driving pleasure 

4Control on Laguna GT

4Control technology results in optimum driving precisions for fantastic at-the-wheel sensations, whatever your driving style or speed.

 

Below 60 kph, the rear wheels are designed to turn in the opposite direction from the front wheels, with a maximum angle of 3.5°. This makes maneuvers easier and reduces the turning circle.

 

Above 60 kph, 4Control gives the driver more precision. The rear wheels turn in the same direction as the front wheels, which counters the centrifugal force that tends to push the rear end outwards in bends, considerably improving vehicle stability. You can also take tight bends confidently in complete safety.     

Optimal safety 

4Control was designed to bring you more safety in emergency situations and during sudden braking. With its integrated memory of steering wheel angles, the ECU can detect a “dodge” situation at any moment. The rear turning angle is automatically corrected to ensure vehicle stability, so that drivers keep control of the car in critical situations.

QUIZ: SAFETY

From one generation to the next, vehicle safety is improved. Hence, between Laguna I and Laguna II the number of deaths and serious injuries (in relation to the number of occupants involved) has reduced:
