Understanding the 2017 Mercedes-Benz GL-Class’s Off-Road DNA

The 2017 Mercedes-Benz GL-Class (now the GLS-Class, but for 2017 it was still the GL) was a full-size luxury SUV that blended opulence with a serious dose of capability. While it might not be a rock-crawling specialist, its underlying engineering makes it far more adept in off-road situations than many believe. Mercedes-Benz has a long history of building robust vehicles, and the GL-Class inherits this legacy.

Key Features Contributing to Off-Road Prowess:

• 4MATIC All-Wheel Drive: This is the cornerstone of the GL-Class’s off-road ability. The 4MATIC system is designed to distribute power to the wheels that have the most traction, ensuring you can move forward even when some wheels are slipping.
• Robust Drivetrain: The GLS shared its platform with robust Mercedes-Benz SUVs, meaning it was built with durability and the stresses of varied terrain in mind.
• Advanced Traction Control and Stability Systems: Beyond the mechanical grip of 4MATIC, sophisticated electronic systems constantly monitor wheel speed and vehicle dynamics. They can intervene rapidly to prevent wheelspin and maintain control on slippery or uneven surfaces.
• Available AIRMATIC Suspension: While standard on many trims, the AIRMATIC air suspension system offers adjustable ride height. This is invaluable off-road, allowing you to lift the vehicle for increased ground clearance when navigating obstacles or descending steep inclines.
• Impressive Ground Clearance: Even in its standard setting, the GL-Class offers respectable ground clearance, helping it to glide over rocks and other obstacles that would ground lesser vehicles.
• Powerful Engine Options: The V6 and V8 engines available in the 2017 GL-Class provide ample torque, essential for maintaining momentum and easily overcoming challenging inclines or getting unstuck from soft surfaces.

Optimizing Your 2017 GL-Class for Off-Road Adventure

While the 2017 GL-Class is capable out-of-the-box, a few thoughtful considerations can further enhance its off-road performance and your confidence when venturing off the beaten path.

1. Tires: The Most Crucial Upgrade

The tires on any vehicle are its only contact with the ground, making them paramount for off-road grip. The standard touring tires on a luxury SUV are rarely optimized for loose surfaces like gravel, mud, or sand.

• All-Terrain (AT) Tires: If significant off-roading is planned, consider switching to a set of all-terrain tires. These tires have a more aggressive tread pattern with larger voids to help clear mud and debris, and they offer better grip on loose surfaces. Look for options that still offer a reasonable compromise for on-road comfort and noise. A popular choice for discerning owners looking for a blend of on-road manners and off-road capability is the BFGoodrich All-Terrain T/A KO2.
• Tire Pressure: Adjusting tire pressure is a simple yet effective off-road technique. Lowering tire pressure increases the tire’s contact patch with the ground, improving traction and ride comfort on rough terrain. Always do this cautiously and reinflate to recommended street pressures upon returning to paved roads. Consult your owner’s manual for recommended pressures and be aware of the risks associated with significantly reduced pressure, such as increased susceptibility to sidewall damage.

2. Understanding and Utilizing 4MATIC

Mercedes-Benz’s 4MATIC all-wheel-drive system is sophisticated. For the 2017 GL-Class, it typically operates in a rear-biased setting during normal driving, seamlessly shifting power as needed. In off-road scenarios, its ability to detect and compensate for wheel slip is your greatest asset.

• How it Works: When a wheel begins to spin, the 4MATIC system electronically brakes that wheel and sends power to the opposite wheel with traction. This is crucial for maintaining forward momentum.
• Assisted by Traction Control: The Electronic Traction System (ETS) works in conjunction with ABS and ESP to manage traction. It can simulate locking differentials by selectively braking individual wheels. This means that even if one wheel is completely off the ground or spinning freely, the system can still send power to the wheels with grip.

3. Leveraging the AIRMATIC Suspension

If your 2017 GL-Class is equipped with the optional or standard AIRMATIC Dynamic Handling Control, you have a significant advantage in off-road situations.

• Raising the Vehicle: The system allows you to increase the ride height, effectively boosting ground clearance. This is essential for navigating over obstacles, rocky terrain, or deep ruts. Consult your owner’s manual for the specific procedure to engage the higher setting, often activated through the vehicle’s infotainment system or a dedicated button.
• Benefits: Increased ground clearance reduces the risk of bottoming out, scraping underbody components, or getting high-centered.
• Note: While useful, raising the vehicle does alter its center of gravity. Drive with caution and at reduced speeds in the raised setting.

4. Driving Techniques for Off-Road

Even with advanced technology, proper driving technique is vital for safe and effective off-road driving.

• Smoothness is Key: Avoid jerky movements, rapid acceleration, or sudden braking. Smooth inputs are crucial for maintaining traction and preventing damage.
• Momentum Management: Use steady throttle to maintain momentum, especially when traversing softer surfaces like sand or mud. Avoid over-revving the engine, which can cause wheelspin.
• Spotting and Line Selection: If possible, have a spotter guide you through difficult sections. Choose the smoothest line with the least amount of obstacles. Look ahead to anticipate challenges.
• Steering Input: Gentle and deliberate steering inputs are preferred. Avoid sharp turns that can cause tires to dig in or lead to loss of traction.
• Hill Descent: For steep descents, use the vehicle’s low gear and controlled braking. Some models may have a hill descent control feature, but gentle brake application is often sufficient and provides more feedback.
