Interior Excellence and Comfort
The cabin of the 2015 GL-Class is where its luxury positioning truly shines. Mercedes-Benz meticulously crafted the interior to be a haven of comfort, technology, and sophisticated design, making every journey a pleasure for all occupants.
Design and Materials
The dashboard featured a flowing, elegant design with high-quality materials throughout. Soft-touch leather, genuine wood trim (varying by package and trim level), and brushed aluminum accents created an environment that felt both premium and inviting. The attention to detail was evident in every stitch and surface.
Seating and Space
As a full-size SUV, the GL-Class offered three rows of seating for up to seven passengers. The front seats were power-adjustable, heated, and often available with ventilation and massage functions, providing exceptional comfort for the driver and front passenger. The second-row seats offered ample legroom and could slide forward and back to optimize space between the second and third rows.

Infotainment and Technology
The COMAND infotainment system was the centerpiece of the dashboard.

Higher trims and optional packages could add features like a premium Harman Kardon surround sound system, rear-seat entertainment, and enhanced connectivity options. Mercedes-Benz’s approach to technology was to integrate it seamlessly, aiming for intuitive use rather than overwhelming complexity.
Cargo Capacity
When utility is a priority, the GL-Class delivered. With the third-row seats folded, it offered a generous cargo volume. Folding the second row as well opened up a vast space suitable for luggage, sports equipment, or larger purchases. The power liftgate and low load floor further enhanced its practicality for everyday use and weekend getaways.
Ride Quality and Handling

Suspension System
The GL-Class featured a sophisticated independent suspension system. Most models came standard with AIRMATIC suspension, an adaptive air suspension system. AIRMATIC offered adjustable ride height, allowing the driver to raise the vehicle for increased ground clearance when needed (e.g., for off-road conditions or clearing obstacles) or lower it for improved aerodynamics at highway speeds. This system also automatically adjusted damping based on road conditions and driving style, ensuring a smooth and composed ride over imperfections.
Steering and Braking
The power steering system provided a good feel, offering consistent weighting that made maneuvering the large SUV manageable, even in tight spaces. While not a sports car, the GL-Class offered commendable stability during cornering, aided by its standard 4MATIC all-wheel drive and available advanced electronic stability control systems. The brakes were robust, providing confident stopping power commensurate with the vehicle’s size and weight, ensuring safety and driver confidence.
Off-Road Capabilities
While primarily a luxury road cruiser, the GL-Class, especially with the optional Off-Road Engineering package, possessed genuine off-road capability. This package typically included a multi-disc center differential lock, a two-speed transfer case with a low-range gear, and underbody protection. Coupled with the adjustable ride height of the AIRMATIC suspension, the GL-Class could tackle more challenging terrain than many of its competitors, making it a versatile choice for those who ventured off the beaten path.
Safety and Driver Assistance
Safety is a paramount concern for any family vehicle, and the 2015 Mercedes-Benz GL-Class was equipped with a comprehensive array of standard and optional safety features and driver-assistance systems, reflecting Mercedes-Benz’s commitment to protecting its occupants.
Standard Safety Features
Every 2015 GL-Class came equipped with a robust set of passive safety features, including an advanced airbag system (front, side, curtain, and knee airbags), anti-lock brakes (ABS), electronic stability control (ESC), and traction control. The strong, high-strength steel body structure provided a formidable safety cage.
Driver Assistance Technologies
Mercedes-Benz offered a suite of innovative driver-assistance systems designed to enhance safety and reduce driver fatigue during long journeys. These included:
- COLLISION PREVENTION ASSIST: A radar-based collision warning system that could also provide partial autonomous braking to help mitigate the severity of an impact.
- ATTENTION ASSIST: This system monitored driving behavior and detected signs of drowsiness, alerting the driver with visual and audible warnings.
- Active Lane Keeping Assist: Worked to keep the vehicle within its lane by gently nudging the steering back if it detected an unintentional drift.
- Active Blind Spot Assist: Warned the driver if it detected a vehicle in the blind spot and could intervene with braking on one side to help steer the car away from a potentially hazardous lane change.
- DISTRONIC PLUS: An adaptive cruise control system that could maintain a set speed and distance from the vehicle ahead, even stopping and resuming in traffic.
- Parking Assist (PARKTRONIC): Helped the driver find suitable parking spaces and could assist with steering into them.
- 360-Degree Surround View Camera: Provided a bird’s-eye view of the vehicle’s surroundings, aiding in parking and low-speed maneuvering.
These technologies were not just electronic aids; they were instrumental in making the 2015 GL-Class a secure and reassuring vehicle for families. For more information on automotive safety standards, you can refer to resources like the National Highway Traffic Safety Administration (NHTSA).
