The primary purpose of hydraulic suspension is to provide a smooth, comfortable ride while also improving vehicle handling. Hydraulic suspension systems use pressurized fluid to control the movement of the vehicle's suspension components, adjusting the height and stiffness of the suspension automatically. This allows for better shock absorption and the ability to adapt to changing road conditions. For instance, hydraulic systems can adjust the vehicle's ride height to increase ground clearance when off-roading or lower the car at high speeds for improved aerodynamics and stability. These systems are also able to maintain a consistent ride height, regardless of load or weight distribution, which helps keep the car balanced and stable. The ability to absorb bumps and irregularities in the road surface provides a smoother, more comfortable driving experience, especially in luxury cars.
