What to know about the new 2027 Mercedes-Benz S-Class

The 2027 Mercedes-Benz S-Class arrives at Mercedes-Benz Rive-Sud as the most thoroughly updated version within its current generation, with more than half of its components newly developed or re-engineered. As the world's best-selling luxury sedan, it carries forward 140 years of Mercedes-Benz heritage while introducing a fresh visual signature, a redesigned digital architecture, and refined comfort throughout the cabin. For Longueuil drivers who travel between the South Shore and downtown Montreal, the S-Class offers a quiet, composed ride suited to long stretches of Highway 132 or daily crossings of the Jacques-Cartier Bridge. This generation of the flagship sedan brings a new operating system, an updated infotainment platform, and a revised range of electrified six- and eight-cylinder powertrains. From the larger illuminated grille to the new MBUX Superscreen, every detail has been re-examined to elevate the experience for both driver and rear-seat passengers.

What's New on the 2027 Mercedes-Benz S-Class?

Exterior

The 2027 S-Class wears a more confident face with a radiator grille roughly 20 percent larger than the previous design, now featuring four horizontal chrome bars and, for the first time, illumination. Tiny hot-stamped chrome stars within the grille create a three-dimensional depth effect, and an optionally illuminated standing Mercedes star on the hood becomes part of the car's distinctive light signature. The new twin-star DIGITAL LIGHT headlamps establish an unmistakable look both day and night, while a high-gloss black insert visually links the headlamps and grille into a single unified element.

The proportions remain classically S-Class, with a long wheelbase silhouette that suits highway cruising along the South Shore. New 20-inch multi-spoke wheels, produced through high-pressure casting, deliver sharper contours and a 50-cross-spoke pattern finished in Tremolite Metallic High Sheen. At the rear, redesigned taillights with three chrome-framed signature stars reinforce the flagship identity, and a two-piece trim element on the trunk lid in chrome and high-gloss black adds a refined finishing touch. Light projectors integrated into the side sills cast Mercedes-Benz branding onto the ground, turning approach and departure into a small ceremony.

Interior

Inside, the cabin has been reimagined around the standard MBUX Superscreen, which unites a 14.4-inch central display, a 12.3-inch driver display, and a 12.3-inch front passenger display beneath one seamless glass surface. The redesigned dashboard, door trim, and centre console showcase exquisite wood inlays and bring a new sense of spaciousness, with three new trim options including Natural Grain Oak, Natural Grain Amber Brown Herringbone Pattern Wood, and a High-Gloss Metallic Textile Blend. The new multifunction steering wheel reintroduces a rocker switch for Distance Assist DISTRONIC and a roller switch for volume control, based on customer feedback. A new "Beech Brown" upholstery option joins the palette, accented by light contrasting piping and stitching.

Rear passengers benefit from a redesigned environment that can be configured as a four-seat executive cabin. The full-length rear centre console keeps essentials within reach, with concealed storage, wireless and fast-charging USB-C ports, temperature-controlled cupholders, and folding tables for laptop work. With the optional Rear Comfort Package Plus, the executive rear seat reclines up to 43.5 degrees and adds neck and shoulder heating, a leg and footrest, massage functions, and seat belt presenters. Standard heated seat belts deliver a gentle warmth on cold Quebec mornings, while the new electric cabin air filter renews the interior air approximately every 90 seconds.

Features

Powertrain

The 2027 S-Class lineup is built around two refined electrified powertrains. The Mercedes-Benz S 500 4MATIC uses a six-cylinder M 256 Evo engine producing 375 hp, with torque now increased to 443 lb-ft and a brief overtorque function delivering up to 472 lb-ft for situations such as passing or dynamic acceleration. A more powerful electric auxiliary compressor, optimized intake and exhaust ports, and a revised intake camshaft sharpen response, while additional insulation reduces noise and vibration. The Mercedes-Benz S 580 4MATIC steps up to a new V8 (M 177 Evo) producing 530 hp and 553 lb-ft of torque, available across a broad rpm range from 2,500 to 4,500 rpm.

Both engines feature a 23-hp integrated starter generator paired with a 48-volt electrical system, enabling coasting, boost, and recuperation functions for smoother operation and improved efficiency. The V8 introduces a flat-plane crank with a new firing order, reducing rotating mass and internal vibration so the engine revs more freely. All 2027 S-Class models come with 4MATIC fully variable all-wheel drive, which continuously adjusts torque distribution between the front and rear axles to suit conditions, providing reassuring traction when winter weather rolls in across the South Shore. Standard AIRMATIC air suspension with intelligent damping uses Car-to-X data to adjust before encountering road irregularities, and optional E-ACTIVE BODY CONTROL regulates each wheel individually.

Technology

At the centre of the digital experience is the Mercedes-Benz Operating System (MB.OS), a supercomputer that integrates every domain of the vehicle, from driver assistance to infotainment, and stays current through over-the-air updates. The fourth-generation MBUX infotainment platform powers the new MBUX Virtual Assistant, which uses generative AI from multiple agents to enable natural, multi-turn conversations with short-term memory. Three avatars are available, including the classic blue Mercedes star, a human-like figure that emerges from a cloud of stars, and "LittleBenz" with an expressive face. MBUX Surround Navigation uses Unity game-engine graphics to display a real-time 3D representation of the vehicle and its surroundings, while the optional MBUX Augmented Reality Head-up Display projects guidance cues onto the road ahead.

For productivity, an enhanced Microsoft Teams app supports video conferencing from both the front and rear seats, using interior cameras with safety safeguards that disable video for the driver while moving. Standard 4.5-degree rear-axle steering improves manoeuvrability, with optional 10-degree rear-axle steering reducing the turning circle by nearly 6.5 ft. Driver assistance technology includes up to ten exterior cameras, five radar sensors, and twelve ultrasonic sensors, working together with MB.DRIVE ASSIST functions such as Steering Assist, Lane Change Assist, and Distance Assist DISTRONIC. The S-Class's adaptive restraint system features PRE-SAFE Impulse seat belt pretensioners, dual-stage load limiters, and up to 15 airbags, including optional rear airbags and beltbags.

Versions

The 2027 Mercedes-Benz S-Class is offered in two main configurations at Mercedes-Benz Rive-Sud: the S 500 4MATIC with the inline-six M 256 Evo engine, and the S 580 4MATIC with the V8 M 177 Evo. Both models include 4MATIC all-wheel drive, the standard MBUX Superscreen, AIRMATIC air suspension with intelligent damping, 4.5-degree rear-axle steering, and an extensive list of comfort and safety equipment. Customers can further personalize their flagship sedan through the AMG Line package, which adds a sportier front and rear fascia, larger AMG wheels up to 21 inches, a sports steering wheel with a flattened lower section, and exclusive sound profiles. The MANUFAKTUR Made to Measure program opens up more than 150 exterior paint colours and over 400 interior colours, along with curated wheel finishes, illuminated door sills, and bespoke leather packages for those seeking a one-of-a-kind sedan.
