This focus on robust powertrains is a defining characteristic of the GL-Class, setting it apart from many competitors.
Engine Options: The Heartbeat of the GL-Class
The 2015 GL-Class was available with a couple of potent engine choices, each offering a distinct flavor of Mercedes-Benz performance. The core models were typically powered by a substantial V8 engine, showcasing the brand’s commitment to delivering ample power and smooth operation. For those seeking the pinnacle of performance, an AMG variant was also part of the lineup, amplifying the driving dynamics to an entirely new level.
The GL 450: A Strong V8 Foundation
The entry point for the V8 power in the 2015 GL-Class was typically the GL 450. While Mercedes-Benz nomenclature can sometimes change regionally, in many markets, this model featured a potent twin-turbocharged 4.6-liter V8 engine. This powerplant was engineered to provide a compelling balance of performance and refinement. It delivered strong acceleration, making merging onto highways and overtaking slower traffic feel effortless, even with a full load of passengers and cargo.
This V8 engine was paired with Mercedes-Benz’s advanced 7G-TRONIC PLUS 7-speed automatic transmission. This transmission is renowned for its smooth shifts and intelligent programming, adapting to your driving style. It ensures that power is delivered precisely when you need it, without abruptness. The result is a driving experience that feels sophisticated and always in control. The GL 450, therefore, offered a significant step up in power and capability over smaller luxury SUVs, making it a compelling choice for families and those who need a capable vehicle for various purposes.
The GL 550: Amplified Power and Presence
Stepping up to the GL 550 meant experiencing an even greater surge of power. This model typically housed a larger twin-turbocharged 4.7-liter V8 engine. This engine was tuned for increased output, providing more horsepower and torque than the GL 450. The extra grunt translated into even quicker acceleration and a more commanding road presence. For drivers who appreciated the luxury and utility of the GL-Class but desired a more potent driving experience, the GL 550 was the clear choice.
Like the GL 450, the GL 550 also utilized the sophisticated 7G-TRONIC PLUS 7-speed automatic transmission. This ensured that the increased power was managed with the same level of smoothness and refinement that Mercedes-Benz is known for. The combination of the larger V8 and the advanced gearbox made the GL 550 a formidable luxury SUV, capable of effortless long-distance cruising and quick bursts of speed when needed. Its performance credentials were, without a doubt, a key selling point.
The AMG GL 63: Unleashing the Ultimate Power
For those who craved the absolute peak of performance, the 2015 Mercedes-AMG GL 63 was the ultimate expression of the GL-Class. This wasn’t just an engine; it was a statement. The GL 63 featured a hand-built AMG 5.5-liter V8 biturbo engine. This powerhouse delivered breathtaking acceleration and a driving experience that blurred the lines between a luxury SUV and a high-performance sports car. The sheer force generated by this engine was phenomenal, transforming the GL-Class into a genuine performance machine.
Working in conjunction with this monstrous engine was an AMG-tuned version of the 7-speed automatic transmission, often referred to as the AMG SPEEDSHIFT PLUS 7G-TRONIC. This transmission was calibrated to handle the immense torque and provide faster, sportier shifts, further enhancing the AMG’s dynamic capabilities. The AMG GL 63 represented the zenith of the 2015 GL-Class lineup, offering unparalleled power and a truly exhilarating driving experience for those who could afford its premium performance.

This impressive towing capability, combined with its luxurious interior and advanced safety features, makes the 2015 GL-Class a versatile vehicle for both daily use and adventurous getaways.
Drivetrain and Suspension: Engineered for Stability and Comfort
Power isn’t much good without precise control. The 2015 GL-Class features advanced drivetrain and suspension systems designed to manage its power effectively, ensuring a comfortable ride and confident handling.
4MATIC All-Wheel Drive
Every 2015 Mercedes-Benz GL-Class comes standard with 4MATIC all-wheel drive. This sophisticated system continuously distributes power between the front and rear axles, optimizing traction and stability in various driving conditions. Whether you’re navigating slippery roads during inclement weather or accelerating hard, 4MATIC ensures that power is applied effectively to maintain control and provide a secure feel. For more information on the benefits of AWD systems, you can refer to resources from automotive engineering societies like the SAE International.
AIRMATIC Suspension System
The GL-Class is equipped with the AIRMATIC suspension system. This adaptive air suspension adjusts the ride height and damping characteristics based on driving conditions and speed. At higher speeds, the vehicle can lower itself for improved aerodynamics and stability. In rougher conditions, it can raise the ride height for increased ground clearance. The system provides an exceptionally smooth and composed ride, absorbing road imperfections without sacrificing handling. It’s this blend of comfort and dynamic capability that defines the luxury SUV experience.
Fuel Economy and Environmental Considerations
While the focus is on “ultimate power,” it’s important to acknowledge the fuel economy aspects, especially for a vehicle of this size and engine displacement. The 2015 GL-Class, with its V8 engines, is not designed for hypermiling, but Mercedes-Benz engineers have worked to optimize efficiency where possible.
Official EPA estimates for the 2015 GL-Class typically looked something like this:
| Model | City MPG | Highway MPG | Combined MPG |
|---|---|---|---|
| GL 450 4MATIC | 14 MPG | 19 MPG | 16 MPG |
| GL 550 4MATIC | 13 MPG | 18 MPG | 15 MPG |
| AMG GL 63 4MATIC | 13 MPG | 17 MPG | 14 MPG |
These figures are typical for large, powerful luxury SUVs equipped with V8 engines. The twin-turbocharging technology helps to improve efficiency compared to naturally aspirated engines of similar displacement, by allowing for smaller, more efficient engines to produce comparable power. For specific regional ratings and comparison tools, the U.S. Environmental Protection Agency (fueleconomy.gov) is an excellent resource.
