A truly high-performance luxury SUV must excel in both responsive handling and a serene ride. The Mercedes-Benz GLS 450 achieves this delicate balance, thanks in large part to its standard AIRMATICĀ® air suspension system.
AIRMATICĀ® Air Suspension Explained:
AIRMATICĀ® is an adaptive air suspension system that replaces traditional coil springs with air springs. This allows for several key performance and comfort advantages:
- Variable Ride Height: The ride height can be adjusted. It can be lowered for easier entry and exit, or for improved aerodynamics at higher speeds. It can also be raised to provide greater ground clearance for off-road excursions or clearing obstacles.
- Adaptive Damping: The system continuously monitors road conditions and your driving style to automatically adjust the damping force at each wheel. This means a softer ride on smooth highways and firmer damping when you’re driving more dynamically or on rougher surfaces.
- Load Leveling: AIRMATICĀ® automatically maintains a level ride height regardless of passenger or cargo load, ensuring consistent handling and a comfortable experience.
- Sportier Handling: In sport modes, the system can stiffen the suspension and lower the ride height, reducing body roll and making the GLS 450 feel more planted and responsive during spirited driving.
- Off-Road Capability: When raised, the increased ground clearance, combined with 4MATICĀ® AWD, offers surprisingly capable off-road performance for a luxury SUV.
This adaptive capability is what truly sets the GLS 450 apart. It can transform from a cloud-like cruiser on a long road trip to a more engaging and controlled vehicle when the driver decides to push its limits on a winding country road. The level of technological sophistication here is aimed at providing the best of both worlds.
