About This 2018 Mercedes-Benz GLS 550

The GLS 550 sits at the top of the GLS lineup, and this 2018 example demonstrates exactly why.

The Black exterior gives it a bold, authoritative presence whether you're navigating the streets of Hayward or heading out on the open road.

2018 Mercedes-Benz GLS 550 Performance and Engine

Twin-Turbocharged V8 Power

Under the hood, the 2018 GLS 550 packs a 4.7L V8 BiTurbo engine — one of Mercedes-Benz's most celebrated powerplants. This engine produces approximately 449 horsepower and 516 lb-ft of torque, giving the GLS 550 the kind of effortless acceleration you'd expect from a performance car, not a three-row SUV. Paired with a smooth 9-Speed Automatic transmission, power delivery is seamless and refined whether you're merging onto I-880 or cruising on Highway 92 toward the San Mateo Bridge.

Mercedes 4MATIC® All-Wheel Drive

The 4MATIC® all-wheel-drive system adds an important layer of confidence and capability. While the Bay Area doesn't see harsh winter weather, the 4MATIC® system is invaluable for wet pavement, uneven surfaces, and those occasional trips to Lake Tahoe or the Sierra Nevada. The system continuously monitors road conditions and distributes torque intelligently across all four wheels, keeping you planted and in control in virtually any driving scenario.

Mercedes-Benz GLS 550 Features and Interior

Three-Row Luxury for the Whole Family

The GLS 550 is one of the few true three-row luxury SUVs on the market, and Mercedes-Benz didn't cut corners in the second or third rows. Premium leather seating, generous headroom, and thoughtful storage throughout the cabin make long road trips genuinely enjoyable for every passenger. The GLS 550 trim elevates the already generous GLS standard equipment with upgraded upholstery, additional technology features, and enhanced ambient lighting.

Technology and Convenience

The 2018 GLS 550 comes loaded with Mercedes-Benz's COMAND infotainment system, featuring a central display screen, navigation, Bluetooth connectivity, and a premium Burmester surround sound system. Dual-zone or tri-zone automatic climate control keeps everyone comfortable regardless of where they're seated. Additional features typically found on this trim include a panoramic sunroof, adaptive cruise control, lane-keeping assist, blind-spot monitoring, and a 360-degree camera system — making this SUV as safe and tech-forward as it is luxurious.

Mercedes-Benz GLS Reliability and Ownership

The GLS 550 has earned a reputation as one of the more durable luxury SUVs in its segment when properly maintained. Mercedes-Benz's 4.7L BiTurbo V8 is a robust engine with a long track record of reliability, and many owners report the powertrain holding up exceptionally well past 150,000 miles with routine service. As with any European luxury vehicle, staying current with oil changes, spark plugs, and fluid services is key — and using genuine Mercedes-Benz parts or high-quality equivalents makes a meaningful difference in long-term ownership satisfaction.

Prospective buyers should perform a standard pre-purchase inspection, check service records when available, and verify the condition of the air suspension system — a common wear item on luxury SUVs in this segment. Overall, the GLS 550 is widely regarded as a solid long-term ownership proposition, especially at the used price point that S&R Motors is offering.

What does the GLS 550 trim include over base GLS models?

The GLS 550 trim adds significant performance and luxury upgrades over the base GLS 450, including the 4.7L BiTurbo V8 engine (versus a turbocharged inline-6 in lower trims), enhanced leather and interior finishes, upgraded audio, and additional driver assistance technology.
