Mercedes S-Class 2026: Refinement in design, new electronics, proven luxury

When a new S-Class arrives, the automotive world holds its breath for a brief moment. The current Mercedes S-Class has been on the market for almost six years already – only now is there an update of the luxury sedan from Stuttgart.

In a mid-cycle update, the pause in public attention and competition—even as a flagship of the Swabians—is admittedly somewhat shorter, but an S-Class is first and foremost one thing: a new S-Class. Visually, not much fundamental has changed in the refresh. Pure electric powertrains remain with the EQS. For that reason, there are for the top model in the Swabian portfolio new headlights at the front as well as at the rear and a new, markedly more stately grille.

Visually, there’s not much to speak of, admittedly, but the detail work undoubtedly benefits the S‑Class. The illuminated Mercedes star on the hood is both a pleasing and image-promoting gimmick and technically challenging. On the home market, however, this lighting display will not be offered for the time being.

Driver assistance: Level 2 Plus instead of Level 3

The same applies to driver-assistance level three, which in Germany had, until now, been available on Autobahns up to 95 km/h for a lot of money. Here, competition and Mercedes fans, with the facelift of the S223 / V223, had expected an increase in speed to at least 120 km/h and thus a considerably higher real-world benefit. But instead, Level 3 has now been scrapped, and the new S-Class steps back to Level 2 Plus and the technology of the lower-segment CLA. Arguments in favour of this are hard to find despite the low uptake.

Detail-obsessed and with revised engines

Otherwise, much remains the same, while the engines have been revised. The usual broad engine lineup consists of the six-cylinder models S 350d 4matic (230 kW / 313 hp), S 450d 4matic (270 kW / 367 hp), S 450 4matic (280 kW / 381 hp / 640 Nm), the plug-in hybrids S 450e (240 kW / 326 hp), S 500 4matic (330 kW / 449 hp), as well as the eight-cylinder S 580 4matic (395 kW / 537 hp / 750 Nm) – depending on the model as standard- and long-wheelbase versions. The plug-in versions achieve a purely electric range of around 100 kilometers. The powerful twelve-cylinder remains reserved for the armored version of the S 680 Guard 4matic. Later, AMG and Maybach variants will follow.

MB.OS is coming to the S-Class as well

All models are networked by a new vehicle electronics system—the MB.OS operating system—just as the new Mercedes CLA has been so far. The air suspension remains standard; optionally, the S‑model offers, independent of the wheelbase, electronic roll stabilization and a rear axle that can steer by up to ten degrees.

Inside, the occupants enjoy the well-known S-Class luxury with large screens at the front as well as the rear, now detachable remote controls, and a new technology for videoconferencing. In terms of safety, as of now there are up to 15 airbags, heated seat belts and numerous driver assistance systems, leaving little to be desired. Through an expanded manufactory program with more than 150 paints and 400 interior colors, every S-Class can be individualized almost at will. The base model of the Mercedes S 350d 4MATIC starts at €121,356.
