Multi-Chamber air suspension controls the spring characteristics by adjusting the internal volume of the air spring through several chambers and solenoid valves. It covers the disadvantages of general metal spring-type suspension, which has limitations in improving ride comfort. The Genesis G90 housed a multi-chamber air suspension, which consists of a total of three chambers. When it implements a smooth ride, it uses all three chambers, and only uses one chamber during dynamic driving. In addition, the minimum ground clearance is adjusted to four levels according to the driving environment, such as speed and drive mode. Based on navigation data on speed bumps, ramps, and rough roads, it automatically adjusts the vehicle height, spring stiffness, and shock absorber strength to improve riding comfort and prevent damage to the vehicle.
