This article delves into the specifics of the 2017 Mercedes-Benz GLS 550, exploring its key features and specifications that make it a compelling choice in the luxury SUV segment.
The exterior of the 2017 GLS 550 is marked by distinctive styling cues and practical features. It comes standard with 21-inch alloy wheels, a step up from the 19-inch wheels on the GLS 450, enhancing its assertive stance. The self-leveling air suspension ensures a comfortable ride, automatically adjusting to maintain optimal vehicle height regardless of load. Power-folding auto-dimming side mirrors, automatic headlights, LED running lights and taillights, a sunroof, and automatic wipers all contribute to convenience and safety. Roof rails add to its utility, while rear privacy glass provides passenger comfort. A power liftgate and Mbrace Connect remote vehicle access, accessible via a smartphone app and including remote start, further enhance the user experience. Every 2017 GLS-Class model, including the GLS 550, is equipped with all-wheel drive and a multimode terrain selector located on the center console, preparing it for varied driving conditions.
Inside, the 2017 Mercedes-Benz GLS 550 is appointed with luxury and technology. MB-Tex premium vinyl upholstery, heated front seats, and a 10-way power driver’s seat with four-way power lumbar support ensure driver and front passenger comfort. Driver-seat memory settings, a power-adjustable leather-wrapped steering wheel, and an auto-dimming rearview mirror add to the personalized driving experience. Genuine wood trim and dual-zone automatic climate control create a refined and comfortable cabin environment. The COMAND infotainment interface, featuring both a control knob and a touchpad, along with an 8-inch central display, provides access to vehicle functions and entertainment. A rearview camera aids in parking and maneuvering, while Bluetooth connectivity enables hands-free calling and audio streaming. A 115-volt household-style power outlet and a sound system with HD radio and dual USB ports cater to modern connectivity needs.
Moving beyond the standard GLS 450 features, the GLS 550 incorporates many desirable upgrades as standard. Features that are part of optional packages on the GLS 450, such as keyless entry and ignition, a power front passenger seat with memory settings, lighted door sills, multicolor ambient lighting, a navigation system with real-time traffic, voice controls, Apple CarPlay, and satellite radio are all standard on the GLS 550. The GLS 550 also includes notable safety features that are part of the Premium package for lower trims.
Additional available features for the 2017 GLS 550 include the Lighting package, which provides adaptive LED headlights and automatic high beams for enhanced visibility. The Parking Assist package adds front and rear parking sensors, an automated parallel-parking system, and a surround-view camera system to simplify parking in tight spaces. Further options include three-zone automatic climate control, ventilated front seats, leather upholstery, a premium 13-speaker Harman Kardon sound system with a CD/DVD player and SD card reader, and “multicontour” front seats with massage function and adjustable side bolsters and shoulder supports for ultimate comfort. The GLS 550 also features adaptive suspension dampers and sporty exterior styling cues that distinguish it from the GLS 450, along with soft-close doors and upgraded interior trim that includes wood steering-wheel inserts. For a bolder aesthetic, the optional Night package adds 21-inch black wheels and gloss-black exterior accents.
Under the hood, the 2017 Mercedes-Benz GLS 550 is powered by a robust 4.6-liter V8 engine, a significant upgrade from the GLS 450’s V6. This V8 engine delivers 449 horsepower and 516 lb-ft of torque, providing strong acceleration and ample power for various driving situations. Like the GLS 450, the GLS 550 comes standard with all-wheel drive for confident traction and a nine-speed automatic transmission for smooth and efficient gear changes. This powertrain configuration allows the GLS 550 to offer sports-car-like acceleration in a large SUV format.
For those seeking even greater performance, the AMG GLS 63 model is available, boasting a more powerful 5.5-liter V8 engine. However, the GLS 550 provides a compelling balance of power and luxury for most drivers. The 2017 GLS 550 also shares optional features with the GLS 450 and AMG GLS 63, including a panoramic sunroof, heated second-row seats, Designo diamond-quilted leather upholstery, and the Driver Assistance package, which includes adaptive cruise control and advanced safety technologies. The Off-Road package, available for both the GLS 450 and GLS 550, enhances off-road capability with an upgraded multimode terrain selector, a dual-range transfer case, and front underbody protection; on the GLS 450, it also adds the GLS 550’s standard adaptive dampers.
Fuel economy for the 2017 Mercedes-Benz GLS 550 is estimated by the EPA at 16 mpg combined (14 city/18 highway). Despite its powerful V8 engine, the GLS 550 maintains a respectable towing capacity of up to 7,500 pounds when properly equipped, making it a versatile SUV for both family transport and recreational activities.
In conclusion, the 2017 Mercedes-Benz GLS 550 offers a significant step up in performance and standard features compared to the GLS 450. With its potent V8 engine, luxurious appointments, and a wide range of available technology and convenience features, the 2017 GLS 550 remains a strong contender in the luxury SUV market, providing a refined and capable driving experience.
