Air suspension
What is Air suspension?
A suspension system with air bellows instead of steel springs; often height-adjustable, usually a premium option.
Air suspension replaces the usual steel coil springs with air bellows kept under pressure by a compressor. By varying the air pressure the system can adjust the ride height and tune the spring characteristic. Many systems automatically lower the car on the motorway for less air resistance and can raise it on a driveway or rough road.
The advantage is comfort and flexibility: flatter handling and an adjustable height, and on some models a constant ride height regardless of load. The drawback is complexity. Air bellows, compressor and valves are wear parts that can leak or fail over time, and a repair is usually more expensive than with conventional suspension. It appears mainly on heavier and more expensive models and is usually an option, not standard equipment.
On spec sheets we mention air suspension as a factual equipment characteristic where it is available. Whether it is maintenance-sensitive over time depends on model, use and model year; any owner experiences we show as context with a source, not as a model score.
