Mercedes-Benz Debuts 2027 S-Class Debuts With MB.OS Superscreen

Summary

• Mercedes-Benz has pulled the wraps off the most extensive S-Class update ever, with more than half of the flagship’s 2700 components reworked to keep the 2027 limousine ahead of BMW, Audi and Genesis
• The facelift introduces a new flat-plane-crank V8, upgraded hybridized six-cylinder options and an MB.OS supercomputer that links everything from suspension and lighting to an all-new triple-screen MBUX Superscreen
• While the exterior design stays stately with a larger illuminated grille and star-studded lights, the real story is a software-defined, AI‑assisted cabin that turns the S-Class into a rolling boardroom and tech lab for the ultra‑rich

Mercedes is using the 2027 S-Class to restate what a flagship limousine is supposed to be in a post-EQS world. Rather than chasing a separate electric silhouette, the car doubles down on the classic long-bonnet, three-box profile while quietly dropping next-gen computing and driver-assist hardware under the skin. MB.OS acts as a liquid‑cooled supercomputer, feeding data to a fourth‑gen MBUX setup, adaptive suspension and a 27‑sensor safety suite that aims to push the car toward higher levels of supervised autonomy over its life cycle.

Inside, the new MBUX Superscreen spans a 14.4‑inch central display flanked by twin 12.3‑inch driver and passenger screens, while rear occupants get 13.1‑inch monitors and detachable remotes that effectively turn the back row into a connected executive lounge. AI‑driven voice assistance, Google Maps‑based navigation, Zoom and Teams video calls, and over‑the‑air updates position the S-Class as a software‑defined flagship that can evolve long after delivery. It is still obsessively comfort‑first, layering heated seatbelts, intelligent digital vent control and a high‑efficiency air filtration system over Airmatic or E‑Active Body Control to keep the cabin in its own climate‑controlled bubble.

Under the hood, the headline change is the M177 Evo 4.0‑litre V8 with a flat‑plane crank in the S580, pairing 530 hp and 553 lb‑ft with a 48‑volt mild‑hybrid system to deliver near‑AMG shove without the drama. The S500’s updated 3.0‑litre inline‑six gains torque and an overtorque function, while the S580e plug‑in hybrid combines that six with a stronger e‑motor for 576 hp and a longer EV range. Rear‑axle steering up to 10 degrees, cloud‑linked intelligent damping and a broader ADAS stack show Mercedes using the facelift to hard‑reset the S-Class for a decade where SUVs dominate but the chauffeured sedan still has to define the taste level for the entire brand.
