2025 Mercedes-Benz S-Class

The volume 2025 S 500 4MATIC pairs a 3.0L turbo inline-six with the EQ Boost 48V mild-hybrid system for a 442-hp US rating. 2025 is a carry-over year inside the W223 generation, which launched for 2021. The V8 S 580 and the AMG PHEV sit above it.

The S 500's mild-hybrid I6 makes 413 lb-ft in US trim. The V8 S 580 and the S 580e PHEV make considerably more.

US dealer spec sheets for the 442-hp S 500 4MATIC quote 0–60 mph in 4.5 s. KBB's spec page shows 4.9 s, which matches the older European 0–100 km/h figure, so confidence is MEDIUM.

The S 500 inline-six is a segment benchmark for smoothness. The integrated starter-generator hides engine stop/start and fills low-rev torque gaps, so power delivery feels seamless and effortless.

The 9G-TRONIC 9-speed automatic shifts almost imperceptibly in Comfort and kicks down decisively. It rarely hunts, though it is tuned for smoothness over sporting crispness.

4MATIC all-wheel drive is standard on every US 2025 S-Class sedan (S 500, S 580, S 580e and AMG S 63 E Performance). Rear-axle steering is available.

2025 offers four distinct powertrains: the mild-hybrid I6 S 500, the twin-turbo V8 S 580, the I6 plug-in hybrid S 580e, and the AMG V8 plug-in hybrid S 63 E Performance. Two of the four are electrified. There is no BEV S-Class; the EQS fills that role.

The EPA rates the volume 2025 S 500 4MATIC (3.0L turbo I6 with a 48V mild hybrid) at 24 MPG combined, which is good for a full-size luxury sedan. The V8 S 580 drops to 21 MPG.

The EPA city rating is 21 MPG for the S 500 4MATIC. Mild-hybrid assist helps, but the heavy AWD platform limits stop-and-go efficiency.

The EPA highway rating is 31 MPG, which is respectable for a roughly 4,900-lb flagship sedan.

A 20.0-gallon tank at the EPA's 24 MPG combined gives roughly 480 miles per tank on the S 500 4MATIC.

fueleconomy.gov estimates $3,350 a year on premium gasoline at 15,000 miles per year. That is above the top of the sedan band, mainly because of the premium-fuel requirement.

Every gas 2025 S-Class trim requires premium unleaded, and no regular-fuel, flex-fuel or diesel option exists. The S 580e PHEV also uses premium and needs home Level 2 charging to deliver its savings.

NHTSA has not crash-tested the W223 S-Class (2021+), and 2025 is a carry-over year within that generation. Inferred at 5 stars on the strength of the flagship's structure and extensive standard restraint tech (PRE-SAFE Impulse Side, front center airbag, available rear-seat frontal airbags) and the predecessor W222's 5-star record — the same treatment the 2026 card and segment peers (A8, 7 Series) receive.

IIHS has not run a full crashworthiness battery on the W223 S-Class and it does not appear on the 2025 Top Safety Pick/TSP+ lists — typical for low-volume large luxury flagships. Recently tested Mercedes sedans have earned Good crashworthiness results, but without a completed award-eligible slate it cannot score in the award band.

Unlike the C- and E-Class, where core Level 2 features sit in the optional Driver Assistance Package, the 2025 S-Class includes the package as standard on every US trim (S 500 4MATIC, S 580 4MATIC, S 580e): Active Distance Assist DISTRONIC, Active Steering Assist, Active Lane Change Assist, Active Blind Spot Assist, Active Brake Assist with cross-traffic function, Active Emergency Stop Assist and PRE-SAFE PLUS, plus a surround-view camera. No meaningful safety feature is trim-gated.

Standard Active Brake Assist with cross-traffic and turning functions covers vehicles, pedestrians and cyclists, including intersection scenarios and night operation, using the S-Class's stereo camera and multi-radar array. IIHS has not tested the W223, so this score leans on the consistently strong front-crash-prevention results of other Mercedes models with the same sensor suite.

Active Blind Spot Assist with braking intervention, rear cross-traffic alert with braking, and exit warning are all standard, so no package is needed. Coverage is comprehensive, matching or beating the BMW 7 Series.

Standard Active Steering Assist uses map data to anticipate curves and is widely praised for smooth centering without ping-ponging. It is paired with Active Lane Change Assist, which completes signaled lane changes on its own.

Standard DISTRONIC adaptive cruise works across the full speed range, including stop-and-go, and adjusts speed for posted limits, curves and roundabouts using route data. Paired with Active Steering Assist, it gives one of the most refined highway-assist experiences in the luxury class.

The 2025 S-Class offers DRIVE PILOT, a certified SAE Level 3 conditional-automation system that lets drivers take their eyes off the road in congested highway traffic. Its operating area is narrow — approved highways in California and Nevada, at roughly 40 mph or less behind a lead vehicle — so coverage trails Super Cruise and BMW's Highway Assistant, but its eyes-off capability keeps it in the top band.

Multibeam LED headlights with adaptive high beam are standard. The optional DIGITAL LIGHT system has about 1.3 million micromirrors per lamp, shaping a glare-free high beam and projecting guidance symbols onto the road. IIHS has not rated the W223's headlights, but the hardware leads the class.

The long hood, high beltline and thick rear pillars limit natural sightlines, as on most flagship sedans. Standard surround-view cameras, front and rear parking sensors with Parking Assist, and available rear-axle steering compensate well in tight spaces.

Large rear doors and long-wheelbase legroom make rear-facing seats easy to install, with outboard lower LATCH anchors and top tethers. The anchors sit behind covers and take a little digging, and the optional executive rear seats make a three-across install harder.

The 2025 S 500 4MATIC seats five as standard.

Front headroom is generous for a sedan.

Front legroom is average for the class.

The long-wheelbase-only US body gives the rear seat ample headroom.

The rear seat has limousine-grade legroom, which is the point of the US-market long wheelbase.

The trunk is small for a full-size sedan, and the seatback offers only a pass-through.

The car has a covered console, wireless charging and decent door bins, plus available rear console and folding-table options, but no standout storage tricks.

Standard active multicontour front seats with massage are widely praised, and the reclining executive rear seats are class benchmarks. Comfort headrests became standard for 2025.

Standard AIRMATIC with adaptive damping gives a plush, controlled ride that leads the segment.

Acoustic glazing and heavy insulation make it one of the quietest cars sold.

Heated and ventilated massaging front seats are standard. For 2025, though, the heated steering wheel moved into a $3,700 Warmth & Comfort package and quad-zone climate became optional, a small step back.

For 2025 the US S-Class opens with the S 500 4MATIC (AWD only, mild-hybrid inline-six) at $117,750 plus $1,150 destination. That is far above the $55K sedan band ceiling, so it scores at the floor.

The S 580 4MATIC (twin-turbo V8 with EQ Boost) is the volume S-Class. It is $128,600 + $1,150 destination, and typically gets Warmth & Comfort, Driver Assistance and Executive Rear-type packages, landing around $134K–$140K. The S 580e PHEV and Maybach variants cost more.

Flagship German sedans sit at the top of the sedan maintenance range. Dealer Service A/B visits, AIRMATIC air suspension, rear-axle steering and a dense electronics suite make years 4–5, after the 4-yr warranty, expensive.

The S-Class is among the steepest-depreciating vehicles in the US, typically losing 60–65% over five years. This tracks the BMW 7 Series and Audi A8 and reflects heavy leasing plus weak demand for used six-figure sedans.

The Mercedes-Benz New Vehicle Limited Warranty runs 4 years / 50,000 miles. That matches BMW and Audi and trails Genesis (5 yr / 60k).

Mercedes offers no separate longer powertrain warranty: powertrain coverage ends with the basic 4 yr / 50k term, below the 5-yr sedan band floor. Only the PHEV's high-voltage battery gets 10 yr / 100k.

There is no multi-year complimentary scheduled maintenance. Owners get unlimited-mileage roadside assistance for the warranty term, a Mercedes me connect services trial and participating-dealer concierge perks. That falls short of the included-maintenance programs from Genesis (G90) and Lexus.

$136,000 volume-trim price minus its estimated resale value after 5 years (38% retained, or about $51,680) leaves about $84,320 in depreciation. Add the projected $9,600 in 5-year maintenance and repairs, and owning this vehicle for 5 years costs about $93,920 in total.

Consumer Reports forecasts 'about average' reliability for the 2025 S-Class, but the forecast leans on data from similar Mercedes-Benz models rather than deep S-Class survey samples. Earlier W223 years drew owner complaints about MBUX/Hyperscreen software, 48V mild-hybrid electrics and body electronics. That trails the Lexus LS (84.8) and BMW 7 Series (80.2), which have stronger records, so this sits just below the peer median.

In the 2025 J.D. Power VDS, Mercedes-Benz scored about 243 PP100 against an industry average of 202. That put it in the bottom third, alongside Ram and Acura and far behind Lexus (140). Consumer Reports brand rankings similarly keep Mercedes in the lower half. It is not at the very bottom like VW or Chrysler, but it is consistently below average.

The W223 generation (2021–) has a heavy NHTSA campaign history, about 25 recalls. They include fuel-pump shutdowns, 80-amp fuse boxes, Camtronic ECU overheat/stall on the V8, eCall failures and front brake hoses. The 2025 model year itself is cleaner. Only one campaign hits the gas volume trims, though it is a serious one: 26V638, front brake hoses that may rupture, expanded to cover 2022–2025 S 500/S 580. The other two 2025 recalls are limited to the S 580e (AVAS software, 94 units) and the AMG S 63 E (hybrid starter software).

The S 500 4MATIC's M256 3.0L turbo inline-six with 48V EQ Boost has been in production since 2018 across GLE/E/S-Class with no widespread failure pattern. The S 580's M177 4.0L twin-turbo V8 is mature but carried the 24V704 Camtronic/ECU overheat-stall campaign on 2021–2023 cars. The 9G-Tronic is proven. Fuel-pump recalls on earlier years and the 48V ISG's added complexity hold this short of the top band.

This is the benchmark full-size luxury cabin, with Nappa leather, open-pore wood, metal trim, 250+ LED active ambient lighting, a 12.8-inch OLED center screen and Burmester 3D/4D audio. Reviewers place it at or near the top of the class with the 7 Series and A8; only ultra-luxury cars like the Celestiq and Maybach sit clearly above.

Sindelfingen Factory 56 assembly gives tight panel gaps, a solid door-close and premium switchgear feel. The quality complaints on the W223 skew toward software and electronics rather than physical assembly. One exception holds it a bit below the best: earlier physical-quality campaigns, such as a headliner/roof-area issue and the fuse-box rework errors (25V255), show assembly and repair-quality slips.

Mercedes-Benz has roughly 380 US dealers, one of the densest luxury networks, ahead of BMW and Audi and covering all major metros. Flagship S-Class owners get loaner and concierge treatment at most stores. Service satisfaction is mid-pack among luxury brands, behind Lexus and Genesis.

Out of warranty, the S-Class is one of the costliest sedans to repair. AIRMATIC air suspension, rear-axle steering, 48V ISG electronics, OLED/Hyperscreen displays and the many ECUs are largely dealer-only parts at flagship pricing, and there is little aftermarket support for the W223. It is more expensive to keep than the LS or G90.

The standard 12.8-inch OLED portrait touchscreen is large and crisp.

Second-generation MBUX is fast and graphically rich, but reviewers criticize the haptic steering-wheel touch pads and touch-only climate controls.

Wireless Apple CarPlay and Android Auto are standard.

"Hey Mercedes" handles natural-language commands well, and native navigation includes augmented-reality video guidance.

Burmester 3D surround is standard, and the optional Burmester 4D High-End system is among the best in any car.

A 12.3-inch digital driver display is standard, and a 3D cluster with eye tracking is optional.

MBUX receives over-the-air updates to software, maps and some ECUs, and features can be bought through the Mercedes me Store.

The Mercedes me app offers remote start, lock and locate. Sources conflict on whether the 2025 phone key is fully standard or only pre-wired, and the services need a subscription after the trial.

USB-C ports in both rows and standard wireless charging, but no household AC outlet.

KEYLESS-GO, hands-free trunk access and push-button start are standard, and phone-as-key is available or standard depending on source.

A 360-degree camera, PARKTRONIC and Active Parking Assist are standard, and image quality is good.

The augmented-reality HUD is class-leading but optional on the S 500, in the $3,000 3D Technology Package.

Huge rear legroom, wide doors and outboard LATCH make car seats easy to fit, but the 12.8 cu ft trunk is small for strollers.

The full Intelligent Drive suite is standard, and the 2025 model adds a front-center airbag. No NHTSA or IIHS crash tests are published.

Superb rear seats, ride and quiet, though quad-zone climate is optional for 2025 and the trunk is modest for a family of luggage.

Smooth mild-hybrid powertrain, AIRMATIC and DISTRONIC make traffic effortless. DRIVE PILOT Level 3 is available in CA/NV.

24 MPG combined on premium fuel and costly consumables make this an expensive commuter, though average for a flagship sedan.

At 208 in long with a 42 ft turning circle without the optional rear-axle steering, it is large in town. Standard 360 cameras and Active Parking Assist help.

There is no US tow rating, and the small trunk and fixed seatback make it unfit for work duty.

Delicate Nappa leather, wood and complex air suspension are luxury-oriented and costly under hard use.

There are no factory hitch, rails, AC outlets or upfit provisions.

An outstanding mile-eater, with a quiet cabin, plush ride, top seats, strong ADAS and about 480 miles of range.

Standard 4MATIC and AIRMATIC lift handle snow and gravel, but low clearance and no tow rating or roof rails keep it on pavement.

The 12.8 cu ft trunk has only a ski pass-through, with no folding rear seats or rails.

Composed and planted, with good body control, but tuned for comfort rather than agility. Optional rear-axle steering sharpens it.

Precise but numb and isolated, as is typical for flagships.

Strong, linear brakes and short stops for a 4,740 lb car.

The 442 hp turbo six with the EQ Boost integrated starter-generator delivers seamless stop/start and smooth 9G-TRONIC shifts.

The powertrain stays near-silent at cruise and refined under load.

The long US-spec wheelbase produces a wide turning circle unless optional rear-axle steering is fitted.

Superb seat adjustability and sightlines, marred by touch-heavy controls and haptic wheel pads.

A brilliant cruiser, but deliberately unemotional behind the wheel.

The 2025 S 500 4MATIC includes 4MATIC AWD, AIRMATIC air suspension, the 12.8-in OLED MBUX centre screen, Nappa leather, Burmester 3D audio, a panoramic roof and the core ADAS suite, and 2025 adds a standard digital key and comfort headrests. However, the heated steering wheel moved from standard to optional for 2025, and rear-seat luxury, Driver Assistance and rear-axle steering upgrades are costly packages. That is competitive with the 7 Series and A8 but well short of the Genesis G90's loaded base car.

At $118,900 (S 500) to roughly $130K+ (S 580) before options, the S-Class delivers benchmark refinement but not bargain content. The Genesis G90 gives most of the experience for about $100K, and the Lexus LS undercuts it. The S-Class is fair value for the class leader rather than a standout deal.

The lineup is very broad: S 500 (mild-hybrid I6), S 580 (mild-hybrid V8) and S 580e PHEV, plus AMG S 63 E Performance and the Mercedes-Maybach S 580/S 680 V12. It spans efficiency-focused, performance and ultra-luxury chauffeur configurations, though every car is long-wheelbase AWD only.

The S-Class remains the best-selling traditional full-size luxury sedan in the US, outselling the 7 Series, A8, G90 and LS. The overall segment is shrinking as buyers move to large luxury SUVs. No 2024 nameplate-level US figure was retrieved (Mercedes reports US sales by segment).

'S-Class' is shorthand for the pinnacle of luxury sedans, and the three-pointed-star flagship carries unmatched executive prestige. Only Rolls-Royce and Bentley outrank it on image.

Mercedes-Benz Financial runs lease specials and loyalty/conquest offers on S 500/S 580, and with an outgoing pre-facelift MY2025 in a contracting segment, dealers negotiate below MSRP. Maybach variants still transact near sticker.

MY2025 is the fifth year of the W223 generation (launched for MY2021) and a light carry-over update, with the mid-cycle facelift due next. Buyers get current tech (MBUX, EQ Boost, PHEV) but the pre-facelift car is about to be superseded.

Car and Driver, MotorTrend and Edmunds widely treat the W223 as the luxury-sedan benchmark for ride, refinement and cabin tech, and it routinely tops full-size luxury comparisons. The Genesis G90 and Lexus LS occasionally win value-weighted verdicts.
