Hydropneumatic suspension

Up to 3.5 times more efficient when lifting and levelling

During lifting and levelling, a large proportion of the energy in air suspension is lost in the compressor chain: of the energy used, only around 19.8% reaches the lifting and lowering movement itself. Under comparable conditions, hydropneumatic suspension achieves an efficiency of around 69% at the cylinder. This amounts to an efficiency difference by a factor of approximately 3.5. This advantage is particularly relevant for vehicles that stop and level frequently, such as in urban logistics and passenger transport. Lower energy consumption per cycle contributes to greater range and higher availability.

Less installation space required

Hydropneumatic suspension systems operate at significantly higher system pressures than air suspension. The same load-carrying capacity is therefore delivered with more compact components, requiring less installation space around the axles. This gained space is particularly valuable in electric vehicles: it creates room for additional battery capacity, more seats or greater load volume, without the need to fundamentally change the vehicle concept.

Fewer separate components, simpler system

Hydropneumatic suspension combines multiple functions in one integrated system. As a result, fewer separate components are required and vehicle integration becomes simpler. Damping is integrated into the suspension and tuned to the application. Roll stabilisation is integrated via cross-connection, meaning additional dampers and (parts of) stabiliser components can often be eliminated. For vehicle manufacturers, this results in a clearer and easier-to-integrate platform. For fleet operators, it means fewer maintenance points and a lower risk of failures.

Lower system weight

Overall, hydropneumatic suspension is lighter than a comparable air-suspension solution. The suspension cylinders themselves may be heavier, but components such as the air-suspension support and anti-roll bar are no longer required. Net result: a weight reduction of up to approximately 5%, depending on the vehicle configuration. Less weight translates directly into lower energy consumption, greater range or higher payload.
