2027 mercedes maybach gls 680When Mercedes-Maybach introduced the GLS 600 in 2019, it signaled a deliberate push to conquer the full-size ultra-luxury SUV segment-a space historically dominated by traditional European coachbuilders. For the 2027 model year, the flagship returns as the Mercedes-Maybach GLS 680, receiving a comprehensive mid-cycle overhaul focused on mechanical updates, cabin isolation, and an overhauled electronic architecture.Set to arrive at U.S. dealerships in late 2026, the updated GLS 680 pairs significant powertrain improvements with the brand's proprietary operating system (MB.OS), addressing both driving dynamics and rear-cabin executive comfort.2027 mercedes maybach gls 680Mechanical UpdatesAt the heart of the GLS 680's update is the M 177 Evo, the latest iteration of Mercedes-AMG's twin-turbocharged 4.0-liter V8 engine. Outputs have risen substantially to 603 horsepower and 627 lb-ft of torque, an increase of 53 hp and 89 lb-ft over the outgoing model.SpecificationPrevious GLS 600New GLS 680Engine4.0L Twin-Turbo V84.0L Twin-Turbo V8 (M177 Evo)Horsepower550 hp603 hp (+53 hp)Torque538 lb-ft627 lb-ft (+89 lb-ft)Hybrid Architecture48V ISG (First-Gen)48V ISG 2.0 (23 hp boost)To counter the inherent NVH (Noise, Vibration, and Harshness) challenges of high-output V8 engines, Mercedes engineers installed dual Lanchester balance shafts. The powertrain remains supported by a 48-volt hybrid system, providing up to 23 hp of electrical boost alongside coasting functions and seamless engine restart.AdvertisementAdvertisementOn the chassis front, several key developments aim to sharpen the heavy SUV's road manners. First, a recalibrated steering rack offers a faster ratio, aiming to reduce the dead-center lethargy typical of long-wheelbase SUVs and improve turn-in precision. Next, the standard air suspension now incorporates cloud-based Car-to-X data, allowing the adaptive dampers to pre-adjust based on road surface hazards reported by vehicles traveling ahead. And also, there's the optional E-ACTIVE BODY CONTROL. Operating via four 48-volt electro-hydraulic motor-pump units, this active suspension system calculates road conditions 1,000 times per second. In its dedicated CURVE driving mode, the system leans the body into turns by up to three degrees to reduce lateral g-forces on passengers.2027 Mercedes-Maybach GLS 680: All The Details2027 Mercedes-Maybach GLS 680: All The DetailsView Gallery63 photosUltra-Posh InteriorInside the cabin, the Maybach GLS 680 focuses heavily on occupant comfort, starting with multi-contour front seats featuring cushion vibration massage and executive rear seats that extend massage coverage down to the calf rests. Breathing room is prioritized through a multi-stage ionization filter that completely recycles the interior air every 90 seconds. Entertainment is handled by a 710-watt, 15-speaker Burmester 3D Surround System with Dolby Atmos, while those seeking extra personalization can select a hand-stitched leather headliner crafted by the bespoke MANUFAKTUR department.NVH and Interior RefinementUltra-luxury buyers place a premium on cabin silence, and Mercedes-Maybach has responded with an extensive acoustic package. High-density non-woven insulation lines the transmission tunnel and engine bulkhead, while targeted acoustic foam seals structural cavities within the bodyshell. The engine cover itself incorporates newly developed dampening material to suppress high-frequency combustion noise.AdvertisementAdvertisementVisually, the cabin gains the MBUX Superscreen layout, housing three 12.3-inch displays under a single glass surface. Traditional mechanical climate vents give way to illuminated glass housings with freely floating "gondolas" for direction control.Exterior Styling and Wheel EngineeringThe GLS 680 adopts an updated front fascia, anchored by a revised radiator grille featuring an illuminated surround and backlit MAYBACH lettering. The headlights incorporate subtle Rose Gold accents and custom start-up light sequences. The optional 23-inch forged wheels feature an engineered center cap mechanism. Utilizing a precision ball-bearing assembly, the Mercedes-Benz star remains fixed in an upright position regardless of wheel rotation-a detail reminiscent of traditional coachbuilding techniques. There are also standard power-deployable running boards, trimmed in anodized aluminum, extend in under a second upon opening a door, complete with LED ground projection.For customers seeking a darker aesthetic, the optional Night Series package trades traditional brightwork for dark chrome exterior accents, dark-anodized running boards, unique seven-spoke 23-inch wheels, and dedicated interior Nappa leather colorways.2027 mercedes maybach gls 680Architecture: MB.OS and Advanced Driver AssistanceUnderpinning the 2027 GLS 680's digital infrastructure is MB.OS, the manufacturer's newly developed software architecture. Driven by a centralized, water-cooled supercomputer capable of 254 TOPS (Trillion Operations per Second), the system manages both infotainment and driver-assistance functions.AdvertisementAdvertisementThe system powers an upgraded MBUX Virtual Assistant featuring generative AI integration, multi-agent processing (incorporating Google Gemini and Microsoft services), and short-term conversational memory. Rear passengers receive independent 11.6-inch full-HD touchscreens supported by integrated video-conferencing cameras and removable MBUX remotes.In terms of automated driving, the hardware suite supports MB.DRIVE ASSIST PRO. Standard active safety includes enhanced 360-degree parking assistance, automatic reverse maneuvering along recorded paths, and a dedicated Rim Protection Warning to prevent wheel rash against curbs.Made-in AmericaThe 2027 Mercedes-Maybach GLS 680 will continue to be manufactured at the Mercedes-Benz assembly plant in Tuscaloosa, Alabama.AdvertisementAdvertisementWhile the core unibody shares the main line with standard GLE and GLS models, the Maybach variants are pulled from the regular production flow for hand-finishing. A specialized team (trained at the Maybach MANUFAKTUR facility in Sindelfingen, Germany) installs the bespoke interior appointments, custom leatherwork, and vehicle-specific trim in a two-person assembly process before final factory sign-off. Pricing and detailed market-specific equipment lists will be released closer to the vehicle's late-2026 launch.
