The 2017 Mercedes-Benz GLS 550 stands as a beacon of luxury and robust performance in the full-size SUV segment. Building upon the already well-appointed GLS 450, the GLS 550 elevates the driving experience with a potent V8 engine, enhanced features, and distinctive styling cues, making it a compelling choice for discerning drivers seeking both opulence and power. This model year of the Mercedes-Benz GLS-Class continues to offer a blend of sophistication and capability that is hard to match.
The exterior of the 2017 Mercedes-Benz GLS 550 immediately sets it apart with its assertive stance and premium details. It comes standard with substantial 21-inch alloy wheels that not only enhance its visual appeal but also contribute to its confident road presence. Adaptive suspension dampers are also standard, refining the ride quality and handling dynamics. Power-folding auto-dimming side mirrors, automatic headlights, LED running lights and taillights, a sunroof, automatic wipers, roof rails, rear privacy glass, and a power liftgate are all carried over from the GLS 450, ensuring convenience and a comprehensive suite of exterior features. Unique to the GLS 550 are sporty exterior styling cues that subtly hint at the enhanced performance capabilities beneath the surface.
Stepping inside the 2017 Mercedes-Benz GLS 550 reveals an interior that is a sanctuary of luxury and technology. The cabin is adorned with upgraded interior trim, including elegant wood steering-wheel inserts, further distinguishing it from the lower trims. Soft-close doors add an extra touch of refinement, ensuring a hushed and premium atmosphere. MB-Tex premium vinyl upholstery, heated front seats, a 10-way power driver’s seat with four-way power lumbar support, driver-seat memory settings, a power-adjustable leather-wrapped steering wheel, an auto-dimming rearview mirror, genuine wood trim, and dual-zone automatic climate control create a foundation of comfort and convenience. Electronic features are equally impressive, featuring the COMAND infotainment interface with both a control knob and touchpad, an 8-inch central display, a rearview camera, Bluetooth, a 115-volt household-style power outlet, and a sound system with HD radio and dual USB ports.

For parking ease, the Parking Assist package, another standard feature on the GLS 550, provides front and rear parking sensors, an automated parallel-parking system, and a surround-view camera system.
However, the heart of the 2017 GLS 550 is its robust 4.6-liter V8 engine. This powerhouse delivers a significant leap in performance compared to the GLS 450, churning out 449 horsepower and 516 lb-ft of torque. This substantial power translates to sports-car-like acceleration for a vehicle of this size, making the GLS 550 not just luxurious but also exhilarating to drive. Like the GLS 450, it comes standard with all-wheel drive for confident handling in various conditions and a nine-speed automatic transmission for smooth and efficient power delivery. The GLS 550 pictured exemplifies this blend of power and sophistication, showcasing its standard turbocharged V8 engine.

For those seeking enhanced capability, an Off-Road package is available, featuring an upgraded multimode terrain selector, a dual-range transfer case, and front underbody protection.
While the AMG GLS 63 represents the ultimate performance variant in the GLS lineup, the 2017 Mercedes-Benz GLS 550 strikes an excellent balance, offering potent V8 performance with a wealth of luxury features as standard.
