It’s a marvel of engineering that combines air springs with adaptive dampers for unparalleled ride quality and handling.

Here’s a breakdown of the primary components you’ll find:

AIRMATIC Air Springs

Instead of traditional metal coil springs, the AIRMATIC system utilizes rubber bellows filled with compressed air. These air springs are central to the GL-Class’s ability to offer a plush ride and self-leveling capabilities.

Function: They support the vehicle’s weight and absorb jolts by adjusting the air pressure within the springs.
Benefits: Allows for adjustable ride height and a consistently smooth ride, regardless of load. They can also stiffen to improve handling during spirited driving.
Maintenance: Air springs can develop leaks over time, leading to a saggy ride height or an uneven stance.

Adaptive Dampers (Shock Absorbers)

These aren’t just standard shock absorbers. The adaptive dampers in the GL-Class can actively change their stiffness in real-time, responding to road conditions and driving inputs.

Function: They control the oscillation of the springs, preventing the vehicle from bouncing excessively. In adaptive systems, they can stiffen or soften to optimize comfort or control.
Benefits: Provides a balance between a soft, luxurious ride and firm, controlled handling. They adapt to make corners flatter and bumps smoother.
Maintenance: Like any damper, they can wear out, leading to a less controlled ride. Leaks are also a potential issue.

Control Arms and Links

These robust components connect the wheel hub assembly to the vehicle’s frame. They are crucial for guiding the wheels and maintaining proper alignment.

Function: They allow the suspension to move up and down while keeping the wheels aligned and tracking straight.
Benefits: Ensure precise steering response and stable handling.
Maintenance: Bushings within the control arms can wear out, causing clunking noises and affecting alignment.

Stabilizer (Sway) Bars and Links

These are designed to counteract body roll during cornering. The sway bar connects the left and right sides of the suspension, helping to keep the vehicle level.

Function: Limits the body’s tendency to lean when turning.
Benefits: Improves stability and reduces the feeling of being pushed sideways in turns.

How the 2016 GL-Class Suspension Works: The Magic Underneath

The 2016 Mercedes-Benz GL-Class’s suspension system, especially with the optional AIRMATIC setup, is designed to provide a dynamically comfortable and controlled driving experience. It’s an intelligent system that constantly adapts to your driving and road conditions.

Normal Driving (Comfort Mode)

In its default “Comfort” setting, the AIRMATIC suspension prioritizes a smooth ride. The ECU monitors inputs like speed, steering angle, and braking. It then directs the air compressor to fill or release air from the air springs. This allows the springs to be softer, absorbing road imperfections like potholes and uneven surfaces with ease. The adaptive dampers also adjust to a less rigid setting, allowing for more vertical wheel travel and further smoothing out the ride. This makes long journeys incredibly relaxing and isolates occupants from most road distractions.

Spirited Driving (Sport Mode)

When you select “Sport” mode, the system transforms. The ECU stiffens the air springs by increasing the air pressure within them. Simultaneously, the adaptive dampers firm up considerably. This reduces body roll during cornering, sharpens steering response, and provides a more connected feel to the road. It makes the large GL-Class feel more agile and planted, offering a confidence-inspiring experience even on winding roads. This dynamic adjustability is a hallmark of luxury SUVs.

Load Leveling

One of the key advantages of air suspension is its ability to maintain a consistent ride height, regardless of how much weight you’re carrying. When you load passengers or cargo, the suspension sensors detect the change in vehicle height. The ECU then signals the air compressor to add more air to the springs, raising the chassis back to its programmed ride height. This ensures that the handling characteristics remain consistent and that the ride comfort isn’t compromised by a saggy rear end.

Adjustable Ride Height

Beyond automatic load leveling, many GL-Class models allow manual adjustment of the ride height. This is incredibly useful:

Increased Ground Clearance: For traversing rough terrain or obstacles, you can raise the vehicle to gain extra ground clearance. This is particularly beneficial for off-road excursions or navigating challenging driveways.
Easier Entry/Exit or Loading: For enhanced accessibility or when loading heavy items, lowering the vehicle can make it easier for passengers to get in and out, or for cargo to be placed in the rear.

The ability to adjust ride height is a significant advantage for a versatile SUV like the GL-Class, showcasing its adaptable nature for various lifestyle needs.

Self-Diagnostics and Warnings

The sophisticated electronic control system constantly monitors the status of the AIRMATIC components. If a fault is detected—such as a leak in an air spring, a malfunctioning pressure sensor, or an issue with the compressor—the system will typically illuminate a warning light on the dashboard. It may also default to a safe mode, often a firmer, fixed ride height, to allow you to drive to a service center safely.
