After many teasers and leaked details, the world’s definitive luxury sedan is here with all of its promised updates. Say hello to the extensively reworked 2027 Mercedes-Benz S-Class.

Heralded as the most extensively updated model in the company’s nearly century-and-a-half-long history, the new S-Class arrives to replace the original version of the W223, which debuted in 2020.

The W223 is the seventh generation of S-Class. And, it’s arguably the first model since the W126 in the 1980s to get such an extensive makeover, without ushering in a completely-new generation.

The most updated S-Class ever

Normally, the average generational lifespan of an S-Class varies between seven to eight years. With the W223 cresting six years old, a new generation of S-Class would usually have been the next expectation.

But this time around, Mercedes-Benz chose to stick with the W223 platform and extend its series production lifecycle. The reasons behind why Mercedes-Benz stuck with the current W223 platform aren’t clear.

However, Mercedes-Benz does have a history of extending production lifecycles to buy engineers more time to further research and develop new generations and technology.

For instance, Mercedes-Benz updated the W126 in 1985 to prolong its production, since development for the succeeding W140 hit a few snags on the way. It was also to adapt to new and rapidly evolving changes to environmental and safety regulations at the time. And, Lexus caught them off guard from a competitive standpoint.

This time around, with the W223, some believe it’s Mercedes-Benz’s reaction to a slowing EV market after the brand committed to an all-electric future. Others also think it’s to allow more time to further develop a platform to accommodate next-gen autonomous driving tech.

But after its plans to make an all-electric S-Class didn’t pan out in time, Mercedes-Benz likely refocused its efforts on improving the W223 to make the car that we see today. It was also likely a move to adapt to the changing market.

So, what’s new on the updated W223? Over 2,700 components underwent change for the new model, according to the manufacturer.

More than skin-deep changes

Upon first glance, it may look the same as the W223’s overall shape and distinctive details remain. But pay closer attention to the details, and one can see the usual suite of exterior design upgrades.

Such includes new head- and taillight assemblies, a revised and bigger grille, and updated bumper and wheel designs. But it’s on the inside and underneath the sheet metal where the changes truly amount.

For example, an all-new MBUX Superscreen with 13.1-inch displays and the latest software sits in the dashboard, touting next-level generative AI. The system also integrates the latest version of Google Maps, and a completely new “Zero Layer” interface for the graphics and user experience.

The newly updated W223 boasts Mercedes-Benz’s latest MB.DRIVE advanced driver assistance tech. And at the heart of it all is the latest MB.OS central operating system, which unifies all the digital vehicle operations.

MB.OS also allows for greater integration of over-the-air software updates and a simpler ecosystem. The result is better oversight and quality management over the function of all the car’s electronic gizmos.

Mercedes-Benz engineers made significant changes to the car’s assembly to ease serviceability, recyclability and environmental friendliness. For example, the head- and taillight assemblies utilize screws, rather than adhesives, for easier reparability.

Four car parts labeled as recycled materials: underbody cladding from 100% recycled plastics, aluminum side wall with 86% recyclate, thermo-valve housing from recycled airbags, and leather alternative from old tires. — Despite being a symbol of opulence, the new S-Class continues its tradition for being a benchmark in employing recycled materials.

Most of the car’s plastics are recycled from old, retired vehicles. And the interior faux-leather comes from old tires. Even the car’s main heater control valve comes from recycled airbags.

A world-class luxury sedan requires world-class pockets

At launch, the S-Class will continue its use of Mercedes-Benz’s latest M256 3.0-liter inline-six in the base S500. It’s still good for the same 442 horsepower, but torque gets a boost to 443 pound-feet of torque versus the old car’s 413 lb-ft.

The more powerful S580 still gets a V8. More excitingly, though, it gets the new M177 Evo V8 with its new flat-plane crankshaft. The result is 530 hp and 553 lb-ft, versus the previous 496 hp and 516 lb-ft.

For those looking for a hybrid option, the S580e carries on with the new M256 Evo. The electric motor, however, benefits from a bump in 73 horsepower, resulting in a total system output of 576 hp, compared to the old car’s 503.

Obviously, this sort of luxury, performance and technology won’t come cheap. As no S-Class has ever been, well, cheap.

Pricing has yet to be released. Though, Mercedes-Benz said such info will be ready when the S-Class launches later this year.
