What to Know About the 2027 Mercedes-Benz GLS

Mercedes-Benz of Danbury – What to Know About the 2027 Mercedes-Benz GLS

The flagship of luxury SUVs evolves again. The 2027 Mercedes-Benz GLS pairs imposing presence with a serene, technology-rich cabin and the kind of effortless performance that turns long drives into short stories. If you are deciding between moving up from a mid-size SUV or replacing a long-loved luxury vehicle, this new GLS brings the top-tier comfort, intelligence and agility that shoppers ask about most.

Mercedes-Benz positions the GLS as the SUV expression of its flagship values, and the 2027 model leans into that mission with more digital intelligence, striking exterior details and refined powertrains. From the illuminated grille surround to next-generation lighting and a sweeping MBUX Superscreen inside, everything is designed to feel both modern and unmistakably Mercedes-Benz.

Design and Presence

The 2027 GLS announces itself with a confident, heritage-rich front end. A new grille design with optional illumination frames the iconic Star, now available standing proud on the hood for an S-Class inspired signature. Headlamps and taillamps feature a Mercedes-Benz Star pattern that reads as both high fashion and high function, while the latest DIGITAL LIGHT micro-LED technology elevates precision and visibility. Crisp lines, broad shoulders and elegant proportions underscore why the GLS continues to define full-size luxury SUV aesthetics.

• Signature front-end: A new grille with optional illumination and a standing Mercedes-Benz Star create a prestigious first impression.
• Advanced lighting: DIGITAL LIGHT micro-LED headlamps deliver finely tuned beams and an efficient partial high-beam function.
• Refined details: An illuminated chrome surround and Star-patterned lamp signatures reinforce distinctive style day or night.
• Panoramic openness: A large panoramic roof floods the cabin with light and emphasizes the GLS sense of space.

Cabin Experience and Tech

Inside, tranquility and wellbeing take center stage. Three power-adjustable rows seat up to seven, with generous room to settle in and relax. Sound insulation works in concert with the refined powertrains to keep engine, road and wind noise hushed. Available amenities elevate comfort even further, including ENERGIZING AIR CONTROL to help maintain a fresh-feeling cabin environment and a rear entertainment system that can stream, conference and more on dual 11.6-inch HD displays with integrated cameras.

At the heart of the GLS experience is MB.OS, the Mercedes-Benz Operating System that ties together infotainment, assistance features and vehicle functions. The standard MBUX Superscreen stretches across the dash with three 12.3-inch displays, bringing an enhanced Zero Layer interface, MBUX Surround Navigation and an available MBUX Augmented Reality view that overlays guidance onto the real world. The MBUX Virtual Assistant employs conversational AI to understand natural speech and streamline tasks, while navigation is powered by Google Maps for clear routing and robust search. Over-the-air capabilities via the Mercedes-Benz Intelligent Cloud help the GLS stay current long after it arrives in your driveway.

• MB.OS foundation: A unified software architecture powers infotainment, navigation, assistance and updates.
• MBUX Superscreen: Three 12.3-inch displays deliver crisp visuals and an intuitive Zero Layer home experience.
• Virtual Assistant: Conversational, generative AI makes common requests—like setting a destination or temperature—feel natural.
• Augmented guidance: Available MBUX Augmented Reality and Surround Navigation add clarity where you need it most.
• Rear-seat luxury: Dual 11.6-inch HD displays with integrated cameras support streaming, video calls and more.

Performance and Capability

The 2027 GLS lineup emphasizes smooth, confident power. The GLS 450 features a responsive inline six-cylinder with electric assistance for swift, seamless torque delivery. Step up to the GLS 580 for a muscular V8 complemented by an integrated starter generator that sharpens response without sacrificing refinement. Both variants focus on instant, usable performance, making merging, passing and effortless cruising feel second nature.

Dynamic composure comes standard thanks to 4MATIC all-wheel drive with torque on demand and AIRMATIC air suspension with intelligent damping. The system constantly adapts to the road surface to balance comfort and control. For an even more authoritative ride, E-ACTIVE BODY CONTROL is available on GLS 580, actively managing body motions to help the SUV stay remarkably level through corners and over uneven surfaces. The numbers reflect the confidence: expect electronically limited top speed and brisk 0-60 mph times that belie the GLS size.

• Powertrains: Choose a refined inline-six in GLS 450 or a commanding V8 in GLS 580, both with electric assistance.
• All-weather traction: 4MATIC with torque on demand enhances stability and confidence in changing conditions.
• Ride comfort: AIRMATIC air suspension smooths imperfections and adapts to your driving style.
• Advanced body control: Available E-ACTIVE BODY CONTROL helps maintain composure over bumps and through curves.

Ownership, Trims and Personalization

Personalization is central to the GLS appeal. Available AMG Line styling sharpens the SUV stance with distinctive design cues, while the Executive Rear Seat Package Plus focuses on second-row indulgence. Illuminated exterior accents, multiple wheel designs and a curated range of interior materials allow you to tailor the cabin to your taste—sporty, serene or somewhere in between. Wireless device charging, abundant USB ports and rich ambient lighting round out an interior that is as practical as it is polished.
