Passive damping technology to debut on C-Class


The fourth-generation Mercedes-Benz C-Class will be the first vehicle to feature Tenneco’s Monroe OE Solutions MCx valving system for passive vehicle damping. According to Tenneco, when the MCx is integrated with Monroe monotube dampers, the valve’s independent and parallel flow paths can accommodate all piston velocities, allowing the comfort and dynamic control of the setup to be tuned.

The valve also offers open-bleed tuning capability, which creates two additional tuning parameters in rebound and compression. These parameters can be used for rolling comfort and the elimination of ultra-low-velocity vibrations, such as those generated when a vehicle drives over uneven or cracked road surfaces, or by imperfections in wheels and tyres.

“We are proud to partner with Mercedes-Benz AG to debut our MCx valving technology on a vehicle packed with sophisticated technologies and innovations,” said Craig Frohock, group vice president and general manager at Tenneco Ride Control. “Our team worked closely with the customer to deliver levels of comfort, control and consistency that were previously considered unattainable by passive piston valving systems without add-on valves. The resulting ride quality is at the top of its class, delivering plushness and outstanding comfort, as well as agility and control”.
