The 2018 Mercedes-Benz GLS 550 stands as a testament to luxury and robust performance in the SUV market. Building upon the solid foundation of the GLS series, the GLS 550 elevates the driving experience with a potent V8 engine, enhanced standard features, and a suite of optional upgrades designed to cater to the most discerning drivers. For those seeking a full-size SUV that seamlessly blends opulence with commanding performance, the 2018 GLS 550 is a compelling choice.
Under the hood of the 2018 GLS 550 lies a significant upgrade from its GLS 450 counterpart: a twin-turbocharged V8 engine. This powerhouse delivers a remarkable 449 horsepower and 516 lb-ft of torque, providing effortless acceleration and ample power for any driving situation. Compared to the GLS 450’s V6 engine, the GLS 550 offers a noticeable surge in performance, making it ideal for drivers who prioritize power and responsiveness. This enhanced engine is a core differentiator, placing the GLS 550 firmly in the realm of high-performance luxury SUVs.
The 2018 Mercedes-Benz GLS 550 doesn’t just offer raw power; it envelops occupants in a world of premium features right from the base configuration. It inherits many standard features from the well-equipped GLS 450 and then adds its own layer of sophistication. Standard features include 21-inch alloy wheels that enhance its imposing stance, adaptive suspension dampers for a smoother ride, and distinctive sporty exterior styling cues that set it apart visually. Entering the GLS 550 is an experience in itself, thanks to the inclusion of soft-close doors and upgraded interior trim, featuring elegant wood steering-wheel inserts that elevate the cabin’s ambiance.
The interior of the 2018 GLS 550 is a haven of comfort and technology. It boasts premium vinyl upholstery, heated front seats with 10-way power adjustability and memory settings for the driver, and a power-adjustable leather-wrapped steering wheel. Dual-zone automatic climate control ensures personalized comfort for both driver and passenger. Technology is seamlessly integrated with the COMAND infotainment interface, featuring an 8-inch central display, Bluetooth connectivity, and dual USB ports. For added convenience, a 115-volt household-style power outlet is also standard.
Building upon these impressive standard features, the 2018 GLS 550 offers a range of optional packages and standalone upgrades to personalize the vehicle further. While the original article mentions options available for both GLS 450 and 550 like the panoramic sunroof, heated second-row seats, and Driver Assistance package (adaptive cruise control, lane keeping assist, blind-spot monitoring), it’s important to note that many of these are also available to enhance the GLS 550 even further. For a sportier aesthetic, the Night package adds 21-inch black wheels and gloss-black exterior accents. For audiophiles, upgrades include a Harman Kardon sound system or even a Bang & Olufsen audio system. Luxury can be further enhanced with diamond-quilted leather upholstery and multicontour front seats with massage function.
When considering the 2018 Mercedes-Benz GLS lineup, the GLS 550 distinguishes itself from the GLS 450 primarily through its engine and enhanced standard features. While the GLS 450 provides a comfortable and well-equipped entry point into the GLS range, the GLS 550 steps up the game with its significantly more powerful V8 engine and additional luxury appointments as standard. The AMG GLS 63 represents the pinnacle of performance in the lineup, boasting an even more potent V8 engine and sport-tuned components, but the GLS 550 strikes an excellent balance between luxury and performance for everyday driving and occasional spirited excursions.
In conclusion, the 2018 Mercedes-Benz GLS 550 is a compelling choice for those seeking a luxury SUV that delivers both exhilarating performance and a wealth of premium features. Its twin-turbo V8 engine, coupled with its enhanced standard equipment and extensive options list, positions it as a top contender in its class. For buyers prioritizing power, luxury, and the prestige of the Mercedes-Benz brand, the 2018 GLS 550 offers a truly exceptional ownership experience.
