Mercedes Previews Overhauled 2027 S‑Class Ahead of Jan. 29 World Premiere

The flagship will debut MB.OS, marking Mercedes' shift to a proprietary software core.

Overview

  • Mercedes says roughly 2,700 parts—over half the car—are new or revised, positioning the update beyond a typical facelift.
  • Exterior revisions include an upright hood star and a grille Mercedes says is about 20% larger with LED lighting.
  • The new MB.OS integrates 27 sensors with expanded voice control and deeper user personalization.
  • Comfort and dynamics get attention with reworked AIRMATIC damping and a feature that shares GPS‑tagged road rough spots to precondition the suspension.
  • Powertrain plans keep combustion options, with Ola Källenius touting a newly developed cleaner V8 and the V12's continued availability, while some outlets report standard rear‑wheel steering and engine tweaks still to be confirmed at the reveal.
