relatively high speed in a vehicle was if it could easily absorb road irregularities.
While the system has inherent advantages over steel springs, generally recognized in the auto
industry, it also has an element of complexity, so automakers like Mercedes-Benz, British Leyland
(Hydrolastic, Hydragas), and Lincoln have sought to create simpler variants.
This system uses a belt or camshaft driven pump from the engine to pressurise a special hydraulic
fluid, which then powers the brakes, suspension and power steering. It can also power any number
of features such as the clutch, turning headlamps and even power windows. The suspension system
usually features driver-variable ride height, to provide extra clearance in rough terrain.
The suspension setup is referred to as 'oléopneumatique' in early literature, pointing to oil and air as
its main components.
