The Mobile Office reshaped: Rear Cabin Luxury in the 2027 Mercedes-Benz GLS

The 2027 Mercedes-Benz GLS reshapes what a full-size luxury SUV can be. For business leaders who spend meaningful time on the road, the available Executive Rear Seat Package Plus transforms the rear cabin into a space that adapts to the demands of a workday - from video calls to focused thinking to genuine relaxation.

Mercedes-Benz built the GLS around a simple idea: the rear cabin matters as much as the front. The Executive Rear Seat Package Plus delivers on that premise with multi-contour massage seats, new MBUX remote controls that put comfort and entertainment functions at your fingertips, and wireless charging for mobile devices.

The GLS 580 4MATIC accelerates from 0-100 km/h in 4.8 seconds.

Overview

The 2027 GLS is a comprehensive redesign, not a refresh. Mercedes-Benz introduced the MBUX Superscreen as standard equipment - three 12.3-inch displays under a smooth glass surface that spans the width of the interior.

The new MB.OS operating system integrates every function and keeps the vehicle current with over-the-air updates. Cloud-based AIRMATIC damper regulation, also standard, adjusts the suspension before the vehicle encounters a bump.

The lineup includes two models: the GLS 450 4MATIC with a 3.0L inline-six producing 375 hp and 413 lb-ft of torque, and the GLS 580 4MATIC with a 4.0L V8 producing 530 hp and 553 lb-ft.

Both engines feature an integrated starter generator (ISG 2.0) that provides intelligent support at lower engine speeds. The V8 now uses a flat-plane crankshaft instead of the previous cross-plane configuration, which improves throttle response and efficiency. The GLS 450 4MATIC does the same run in 5.4 seconds.

The GLS measures 5207 mm in length with a 123.4-inch wheelbase - 61 mm longer than the GLE. That extra length creates space for three rows of power-adjustable seats. Even the third row accommodates passengers up to 6'4" comfortably. Optional five-zone climate control gives third-row passengers their own dedicated climate zone with roof-mounted air vents.

The exterior design signals the redesign immediately. A new standing Mercedes-Benz star on the hood - optionally illuminated - pays homage to the S-Class. The new radiator grille features a striking chrome frame, contour lighting, and a shimmering Mercedes-Benz star pattern.

Key Specs and Features

The Executive Rear Seat Package Plus is the centerpiece of the rear cabin experience. Multi-contour seats with the Pro massage function deliver the same level of comfort as the front seats.

Generous power adjustability allows rear passengers to find a perfectly tailored seating position with excellent lateral support. A new vibration function uses four precisely placed motors in the seat cushion to deliver a deep-tissue effect that melts away tension.

New MBUX remote controls replace the previous tablets. These controls give rear passengers responsive access to comfort and entertainment functions without reaching forward or asking the driver.

The Executive Rear Seat Package Plus also includes refined details: leather grab handles, an extended comfort centre armrest with an illuminated storage compartment, and a centre console with two cupholders. The occupant seated behind the front passenger can move the front seat forward at the touch of a button.

The optional Rear Seat Entertainment Package adds two elegant 11.6-inch displays and an array of smart features. Rear passengers can stream content, review documents, or stay connected while on the move. Wireless charging for mobile devices keeps phones and tablets ready without cables cluttering the cabin.

The MBUX Superscreen creates a harmonious stage for three 12.3-inch displays. The smooth glass surface delivers a clear, responsive layout. The MBUX Virtual Assistant can engage in complex multi-turn conversations and features expressive avatars for more personal interaction. Digital Extra: MBUX Navigation pairs Google Maps technology with the familiar Mercedes-Benz user interface.

The GLS 580 4MATIC offers optional E-ACTIVE BODY CONTROL - one of the most intelligent SUV suspension systems on the market. The system's control units analyze the driving situation 1,000 times per second and adapt the suspension accordingly.

The GLS 450 4MATIC and GLS 580 4MATIC feature 4MATIC fully variable all-wheel drive (Torque on Demand). The new transfer case also includes a 1:2.93 low-range reduction gear, which allows higher torque transfer to the wheels during off-road driving.

What Sets It Apart

The 2027 GLS is the first Mercedes-Benz SUV to run MB.OS - a powerful supercomputer with extensive reserves for future functions. Every GLS is equipped with ten exterior cameras, up to five radar sensors, and 12 ultrasonic sensors. These sensors work together with a powerful control unit running MB.OS.

Digital Extra: MB.DRIVE ASSIST and Digital Extra: Distance Assist DISTRONIC are standard. Digital Extra: MB.DRIVE PARKING ASSIST, also standard, can detect parking spaces on both sides of the vehicle more quickly and accurately than the previous system.

It also detects spaces that are not marked by white lines. The system can assist with leaving a parking space - even if the vehicle was previously parked manually.

The Digital Extra: Reverse maneuvering function enables the vehicle to automatically reverse part of the route most recently driven, with system support available under certain conditions.

Digital Extra: MB.DRIVE PARKING ASSIST 360 with its 360-degree camera is also standard and offers improved surround view displays. The Digital Extra: Rim Protection Warning displays a top-view distance alert when maneuvering in tight spaces.

The latest generation DIGITAL LIGHT headlamps - standard on the GLS - produce a larger high-resolution light field and are up to 50 percent more efficient than the previous generation.

The new multifunction steering wheel incorporates an responsive control concept with a rocker for Digital Extra: Distance Assist DISTRONIC and a roller for volume control. The newly available "Beech Brown" upholstery choices provide a genuine feeling of home and comfort.

Seat climate control, standard on the GLS 450 4MATIC and GLS 580 4MATIC, gently ventilates the front seats. The system integrates new radial fans instead of the previous axial units in the seat cushions and backrests to increase airflow and improve efficiency.

The GLS Delivers on the Promise

The 2027 Mercedes-Benz GLS is built for people who need their vehicle to do more than transport them. The Executive Rear Seat Package Plus creates a rear cabin that adapts to the demands of a workday - from focused productivity to genuine relaxation.

Multi-contour massage seats, new MBUX remote controls, and wireless charging for mobile devices ensure rear passengers have everything they need within reach. The MBUX Superscreen, standard on all models, integrates every function into a smooth, responsive interface. Cloud-based AIRMATIC damper regulation delivers a ride quality that feels effortless, even over rough pavement.
