The Mercedes-Benz GL-Class has always been more than just a luxury SUV; it’s been a symbol of capability and refined German engineering. For those venturing off the beaten path, or simply navigating challenging urban landscapes, understanding a vehicle’s ground clearance is paramount. This crucial spec dictates how well your vehicle can clear obstacles, wade through water, and maintain stability on uneven surfaces. If you’re curious about how the 2017 Mercedes-Benz GL-Class measures up, and what that means for your adventures, you’ve come to the right place. We’ll break down everything you need to know about its ground clearance and how it contributes to its impressive off-road prowess.
Understanding Ground Clearance: Why It Matters
Ground clearance, often referred to as ride height, is the distance between the lowest point of the vehicle’s undercarriage and the ground. It’s a critical factor for any vehicle that expects to encounter anything beyond smooth asphalt. Think of it as your vehicle’s ability to step over obstacles without scraping or getting stuck.
Why is this so important?
Obstacle Avoidance: Low-hanging branches, rocks, speed bumps, and debris on the road can all pose a threat to a vehicle’s undercarriage. Higher ground clearance means a greater buffer between these hazards and your car’s sensitive components.
Off-Road Performance: For true off-roading, ground clearance is non-negotiable. It allows the vehicle to traverse ruts, rocks, and uneven terrain without damaging the chassis, exhaust system, or drivetrain components.
Wading Depth: While not purely ground clearance, a higher ride height generally correlates with a greater ability to safely drive through shallow water crossings.
Riding Comfort: On rough roads, more ground clearance can indirectly contribute to a smoother ride by allowing the suspension to articulate more freely without bottoming out.
2017 Mercedes-Benz GL-Class: The Numbers Game
When we talk about the 2017 Mercedes-Benz GL-Class, we’re referring to a robust, full-size luxury SUV that was part of the X166 generation. This model was engineered with a blend of sophisticated on-road manners and genuine off-road capability.
For the 2017 model year, the GL-Class typically featured a substantial ground clearance. While official Mercedes-Benz specifications can sometimes be elusive or vary based on specific packages and tire sizes, a commonly cited figure for the standard GL-Class is around 8.5 inches (approximately 21.6 cm).
It’s crucial to note that this figure can be influenced by a few factors:
Tire Size: Larger diameter tires will naturally increase the ground clearance.
Suspension Setup: Models equipped with the optional AIRMATIC air suspension or the more advanced Active Curve System could offer adjustable ride height. This means you could potentially increase the ground clearance for off-road driving and lower it for improved aerodynamics and easier entry/exit on the highway.
The 8.5-inch figure places the 2017 GL-Class in a competitive position within the luxury SUV segment, offering more clearance than many car-based crossovers, and providing genuine confidence for tackling more challenging environments.
Features Enhancing Off-Road Capability
Beyond just the static ground clearance, the 2017 GL-Class was equipped with several features designed to enhance its ability to venture off the pavement.
4MATIC All-Wheel Drive System
The heart of the GL-Class’s traction control is the standard 4MATIC all-wheel-drive system. This sophisticated system distributes power between the front and rear axles, and often between the wheels themselves, to optimize grip in various conditions.
Varied Traction: Whether you’re on slippery mud, loose gravel, or ice, 4MATIC works to ensure that power is sent to the wheels with the most traction.
Stability Control: It works in conjunction with the Electronic Stability Program (ESP) to maintain control during dynamic maneuvers and on slippery surfaces.
Off-Road Modes: The GL-Class, especially when equipped with optional packages, often featured specific off-road driving modes. These modes would adjust throttle response, transmission shift points, and the behavior of the AWD system to better suit different terrains like sand, rocks, or snow.
Optional Off-Road Engineering Package
For the truly intrepid, Mercedes-Benz offered an optional “Off-Road Engineering Package” on certain GL-Class models. This was a significant differentiator and truly unleashed the SUV’s potential:
Multi-Stage Transfer Case with Lockable Center Differential: This allowed for mechanically locking the center differential, preventing wheel slip and ensuring maximum power delivery in extreme off-road conditions.
Skid Plates: Robust underbody protection for the engine, transmission, and fuel tank, shielding them from impacts with rocks and debris.
Increased Wading Depth: When equipped with this package, the wading depth was often significantly increased, allowing for passage through deeper water.
Adjustable Air Suspension: This package often included or was paired with an advanced air suspension system that allowed for significant ride height adjustments.
Having the ability to manually lock the center differential is a key differentiator from many SUVs that rely solely on electronic traction aids. It provides a mechanical advantage for low-traction situations, a feature often found in more dedicated off-road vehicles.
AIRMATIC Air Suspension System
Even on models without the full Off-Road Engineering Package, the available AIRMATIC air suspension provided an advantage.
Adjustable Ride Height: Drivers could often raise the vehicle’s ride height at the touch of a button, effectively increasing the ground clearance for tougher terrain or when encountering obstacles.
Adaptive Damping: AIRMATIC also provides a variable damping system for each wheel, automatically adjusting to road conditions to optimize ride comfort and handling stability.
Other Contributing Factors
Robust Chassis: The GL-Class is built on a strong unibody construction designed to withstand the stresses of off-road driving.
Underbody Protection: Even standard models often feature some level of underbody protection, though the optional package takes this to another level.
