Citroën introduces new suspension: How do you get to be as good as the hydro-pneumatic?

just a few weeks Ago we got dressed up in mourning after confirming that the Vehicle was leaving the technology of hydropneumatic suspension, one of the leaders of its range since it was introduced back in the year 1955 in the times of the Citroën DS “Shark”. Today we dry those tears, and that is that Citroën has already patented a new design of suspension that promises to that same concept of the flying carpet, and doing it with serious intentions of getting to production and at a cost quite content. But how it has managed to Citroen?


Technologies such as the Pothole Mitigation of Ford or the advanced system from BOSE yearn to get that effect of flying carpet

be warned very recently, if you want to enjoy the benefits of the hydropneumatic suspension Hidractiva III, you’re forced to make with a Citroen C5 before this disappears. Behind him, the tech will say goodbye forever to a clear lack of demand on the part of the market, and that is that the suspension technology has advanced so much in these years, and the additional costs of installing a suspension type hydropneumatic each time convinces less to customers of Citroën.

With the presentation of the prototype CITROËN ADVANCED COMFORT® LAB on the basis of a Citroën C4 Cactus, Citroën has introduced a suspension system that is intended to bring to production. This is not a complex system as the design was hydropneumatic, but a single body of the shock absorber which are interconnected multiple cameras to create a shock absorber adaptive without any type of electronic or complex mechanisms with hydraulic or pneumatic. A single-piece, complex in its interior, but perfectly installable in any production vehicle without the need for adaptation.


Two independent chambers and isolated, a to absorb irregularities and the other to absorb large movements

The system is comprised of two hydraulic chambers independent, designed each for a specific function and located each at an end of the shock absorber. While the lower chamber absorbs all the irregularities of the terrain without transmitting vibrations to the rest of the vehicle, the upper chamber only acts in the face of great forces from bumps, speed humps, etc This design in 2 stages promises, according to Citroën, dramatically improve the comfort of the vehicle and provide that feeling of driving flat.

Although this type of adaptive designs are not exactly new, Citroën ensures that the prototype used in the CITROËN ADVANCED COMFORT® LAB has over 30 registered patents. In addition, Citroën asserts that this system has been designed to be used in its entire range of models, getting in addition a product of costs content to allow its implementation from urban models such as the Citroën C3 models of the highest range such as the DS 4 and DS 5.

Without a doubt we’ll miss the hydropneumatic suspension of the Citroën, although it seems that we now have a technology that meets as a substitute… at least on paper.
