Description

Thus gas acts as the springing medium while the hydraulic fluid does all the clever things such as providing damping and levelling. Unlike the hydrolastic system fitted to certain BMC and BLMC cars, the Citroën system relies on an engine-driven pump to pressurise the hydraulic system and it is this power source which enables self-levelling, variable ride height, assisted jacking and zero roll (in the Activa Xantia) and also allows for fully powered braking systems and power steering too. The system provides a soft, comfortable, yet well-controlled ride. The nitrogen springing medium is approximately six times more flexible than a conventional steel system, so self-leveling is incorporated to allow the vehicle to cope with the extraordinary suppleness provided. In the early fifties, France was noted for particularly poor road quality and therefore the only way to maintain a relatively high speed in a vehicle was if it could easily absorb road irregularities. It was this need that also drove the development of the 2CV's interconnected suspension system.In the DS, the high pressure hydraulic system also operated the clutch and gear change. With the introduction of the XM came electronic control of the suspension system - called Hydractive and a refined version of this system was fitted to <b>...</b>
