DESCRIPTION
Air suspension is an old innovative solution to a common vehicle problem. Used various types of metal springs, and air suspension didn't reach mass production until the 1957 Cadillac Eldorado Brougham. No one enjoys driving over potholes with a stiff suspension. Now picture a stuntman jumping out a window and landing on a giant air bag. The fall was dramatic, but the impact was trivial thanks to a cushion of air. Air suspensions work on the same principle, by cushioning the vehicle with an inflated air bag, the compressed air limits the harshness of the bumps in the road.
Other bonuses include increasing ground clearance for off-roading, or automatically lowering the vehicle height at high speed for increased fuel efficiency and handling. Generally, factory air suspension is reserved for larger body-on-frame vehicles that carry large cargo or passenger loads, like full-size cars and SUVs, rather than compacts. Although the aftermarket sees nearly everything; just ask the mini truck fans.
In a vehicle with a suspension, the springs and shocks try to adjust as the passenger and cargo weight increases, but the result isn't ideal. If you've ever driven a pickup near its maximum load, or even a midsize sedan with five adults inside, you know how the suspension can't live up to demands and the ride quality suffers. Air suspension actively counters the suspension compression caused by increased weight, correcting suspension geometry and ride quality through increased pressure inside the air bag. Air suspensions achieve this through several parts, making it an entire sub-system of a vehicle.
