Mercedes takes the 2027 S-Class to the next level with AI, an updated MBUX Hyperscreen, and a more savage V-8 that changes everything.
The Mercedes-Benz S-Class has always been the rolling definition of “because we can.” For 2027, Mercedes doubles down with more AI, more glass, and a nastier V-8 under the hood. The question is simple: does this 2027 Mercedes-Benz S-Class review end with the king still wearing the crown, or just a bigger screen?
A familiar shape, a very different mission
From the outside, the updated 2027 S-Class does not scream reinvention. That is probably wise. The long hood, stately roofline, and clean surfacing still look expensive in a way the BMW 7 Series does not, and they age better than the aggressively styled Genesis G90.
Mercedes focused its effort where buyers actually spend their time: the cabin, the software, and the powertrain. In other words, this 2027 S-Class first drive is less about sheetmetal and more about whether Stuttgart improved the experience or simply added another layer of digital glitter.
The lineup remains centered on the bread-and-butter S500, the six-cylinder S580e plug-in hybrid in some markets, and the V-8-powered S580 4Matic. AMG versions sit above that, but the real story here is the mainstream S-Class trying to stay relevant against fresher, bolder rivals.
- Main rivals: BMW 760i xDrive, Genesis G90 3.5T e-Supercharger, Audi A8L 55 TFSI
- Core test model: 2027 Mercedes-Benz S580 4Matic
- Engine: 4.0-liter twin-turbo V-8 with 48-volt mild-hybrid assist
- Output: about 510 hp and 538 lb-ft
- 0-60 mph: roughly 4.3 seconds
Those numbers matter because the old S580 was already quick. The new one feels quicker, sharper, and less apologetic about it. Mercedes has not turned the S-Class into a sports sedan, thank heaven, but it no longer feels like it is tiptoeing around its own performance.
The new cabin: MBUX Hyperscreen goes full casino lounge
Let’s address the glossy elephant in the room. The updated Mercedes MBUX Hyperscreen now dominates the dashboard with even more visual complexity, deeper AI integration, and enough ambient lighting to embarrass a boutique hotel in Dubai.
At first glance, it is spectacular. Materials remain superb, with rich leather, open-pore wood, precise metal trim, and the kind of switchgear heft Mercedes still does better than Tesla and, frankly, better than BMW lately. But the cabin’s beauty is now fighting for oxygen against its own interface.
Mercedes says the revised MBUX system uses predictive AI to surface functions before you ask for them. In practice, it is better than before at learning routines like navigation destinations, massage settings, climate preferences, and phone contacts. Voice responses are faster, menus are cleaner, and the graphics are sharper.
Still, screen obsession carries a cost. Climate functions buried in touch menus remain less intuitive than proper buttons, and the passenger display still feels like a feature designed to impress in the showroom more than improve life on the road. The old S-Class made luxury feel effortless. This one occasionally makes it feel computational.
- What works: faster processing, better voice control, smarter personalization, excellent display clarity
- What does not: too many touch-dependent controls, distraction risk, unnecessary visual noise
- Best feature: navigation and driver-assistance graphics are class-leading
- Worst feature: basic HVAC adjustments still take too many taps
Against competitors, the S-Class still has the most sophisticated infotainment presentation. But “most sophisticated” does not always mean “best to live with.” The Genesis G90’s simpler interface is easier, and BMW’s latest iDrive setup, while far from perfect, is less determined to turn every interaction into an event.
The V-8 finally remembers it has a reputation to protect
If the cabin is the controversial bit, the powertrain is the redemption arc. The updated Mercedes S-Class V8 in the S580 4Matic feels more alive, more urgent, and better matched to the car’s flagship status.
The 4.0-liter twin-turbo V-8 still works with a 48-volt integrated starter-generator, but calibration changes have sharpened response. There is more immediate shove off the line, cleaner midrange punch, and a richer soundtrack under load. No, it is not an AMG thunderstorm, but it is no longer a muted afterthought either.
Put your foot down and the S580 gathers speed with the kind of contemptuous ease only a big German sedan can deliver. Sixty mph arrives in the low-four-second range, right in line with a BMW 760i xDrive. The difference is character: the BMW feels more eager to show off, while the Mercedes still prefers to humiliate traffic discreetly.
The nine-speed automatic is smooth in normal driving and decisive when pressed. More importantly, the drivetrain now feels cohesive. Older versions of the S580 could seem almost too isolated, as if the engine was happening somewhere in another time zone. This one finally connects the driver to the action without ruining the S-Class brief.
The 2027 S580’s V-8 is not wild by AMG standards. It is wild by S-Class standards, and that matters more.
Ride, handling, and whether comfort still comes first
Here is the good news for traditionalists: the S-Class still rides beautifully. With adaptive air suspension and rear-axle steering, it smothers broken pavement, settles quickly after big impacts, and shrinks around the driver more effectively than a sedan this large has any right to.
On a highway, it remains one of the great mile-eaters. Wind noise is almost absent, road noise is subdued even on larger wheels, and the seat comfort is predictably excellent. The optional executive rear package still turns the back seat into a compelling argument against SUVs.
But Mercedes has added a little more body control and a little less float. That is a welcome change. Previous S-Classes could feel detached to the point of drowsiness; the 2027 model keeps the composure but adds enough discipline to avoid the marshmallow effect that still plagues some luxury barges.
Push it hard on a mountain road and the S580 will not disgrace itself. Rear steering helps rotation, the front end bites cleanly, and the brakes hold up well for a 5,000-plus-pound sedan. Still, if your idea of fun is clipping apexes in a full-size luxury sedan, the 7 Series remains the more athletic tool, absurd grille and all.
- Best for ride comfort: Mercedes-Benz S-Class
- Best for back-seat value: Genesis G90
- Best for driver engagement: BMW 7 Series
- Best interior craftsmanship: Mercedes-Benz S-Class
Does the new tech actually improve the flagship?
This is where the 2027 S-Class gets complicated. Some of the new AI-driven features are genuinely useful, especially the improved voice assistant, smarter route suggestions, and more intuitive driver-assistance visualization. On a long trip, these systems reduce effort in a way that fits the S-Class mission.
Other additions feel like Mercedes trying too hard to prove it still leads the tech conversation. The bigger, brighter, more animated interface can be impressive and irritating in equal measure. Luxury should calm the senses, not bombard them.
The bigger truth is that the S-Class still does the fundamentals better than almost anyone. It feels expensive in every control input. It isolates without anesthetizing. And now, with the stronger V-8 tuning, it has the pace and personality a flagship at this price should absolutely deliver.
That matters in a segment where rivals often overplay one card. The BMW 7 Series is flashier and more extroverted. The Genesis G90 is a value masterpiece but still lacks the final degree of prestige and polish. The Audi A8, meanwhile, feels like it missed the meeting entirely.
Verdict: still the benchmark, but no longer the easiest car to love
So, does this 2027 Mercedes-Benz S-Class review end with an easy win? Not quite. The updated S-Class is still the benchmark full-size luxury sedan in the areas that count most: ride quality, cabin richness, long-distance refinement, and real flagship presence.
But Mercedes has also made it more visually busy and more screen-dependent than necessary. The new Hyperscreen-heavy cabin is not a disaster, yet it is a reminder that progress and improvement are not always the same thing. Some buyers will love the theater. Others will miss the elegance of restraint.
If you want the best all-around luxury sedan in 2026 and beyond, the S-Class remains the one to beat. Get the S580 4Matic, enjoy the newly invigorated V-8, and spend time learning the tech. Just know that the car’s brilliance now comes with a side of digital overkill.
Final verdict: The 2027 Mercedes-Benz S-Class is still on top, but it stays there more because Mercedes sharpened the fundamentals and woke up the V-8 than because it added another acre of glowing glass.
