Overview & Reviews

The Mercedes-Benz S-Class is as synonymous with state-of-the-art luxury and safety features as it is with country club prestige. Mercedes has used its flagship sedan to pioneer many modern technologies, such as airbags, antilock brakes and stability control. Yet as the brand's largest sedan, the S-Class has also offered the most room for rear-seat passengers, making it a favorite of wealthy dads and heads of state alike.

The current Mercedes-Benz S-Class continues that tradition established by its many innovative forbears and remains one of the most desirable choices for a flagship luxury sedan. Besides its wealth of features, opulent interior and bulletproof construction, the S-Class also stands out with an unmatched number of engine and model choices. From the diesel-powered S350 with its epic range and commendable fuel economy to the flagship S65 AMG with its twin-turbo V12 and intense performance, there is a little something for everyone in this lofty price bracket.

Current Mercedes-Benz S-Class
The current Mercedes-Benz S-Class is distinguished by aggressive fender flares and a stately profile that's emphasized by a rising character line. The cabin is elegant, with a minimal number of buttons thanks to the multifunction COMAND controller mounted between the seats.

There are six trim levels that correspond to engine choice. The range starts with a pair of fuel-efficient options. The S350 Bluetec features a diesel-powered V6 good for 240 horsepower and 25 mpg combined. The S400 Hybrid comes with a small electric motor that aids its gasoline-powered V6 to the tune of 295 total hp. Fuel economy is strong for a full-size luxury sedan at 22 mpg combined, but that's obviously worse than the slightly quicker and cheaper S350.

For a more traditional S-Class experience, the S550 is the bread-and-butter model that produces 429 hp from its twin-turbo V8. Next up is the S600 and its 510-hp twin-turbo V12. Finally, there are the high-performance, range-topping AMG models. The S63 AMG (536-hp twin-turbo V8) and S65 AMG (621-hp twin-turbo V12) get AMG-specific suspension, steering, brakes and styling elements. All S-Class models are equipped with an automatic transmission (seven speeds in all but the V12 versions, which have a five-speed unit) and rear-wheel drive. The S550 can be had with "4Matic" all-wheel drive.

We could list the number of standard and available features on the S-Class, but we would be here all day. In short, if there's a feature you can think of, you can probably get it on Benz's flagship. Those who intend to frequently carry around passengers should pay special attention to the wealth of backseat comfort and entertainment options available.

In reviews, we've found that the Mercedes-Benz S-Class remains a regal car regardless of which numbers line its trunk lid. If you want fuel economy from your high-luxury sedan, the S350 delivers, while the V8 and V12 models get you swifter 0-60-mph times. The S-Class doesn't handle as crisply as some other competing flagships, but it has a luxurious cabin and a balance of competent handling and a serene ride that is second to none. In total, the S-Class may be priced higher than its competitors, but its superior craftsmanship, engineering and attention to detail should make it worth the extra dough.

Used Mercedes-Benz S-Class Models
The current, fifth-generation S-Class debuted in 2007. Not much has changed in terms of design or features, but Mercedes has altered the engine lineup considerably. Until 2010, only the V8- and V12-powered models were available. The S400 Hybrid debuted for 2010, while the S350 Bluetec dawned for 2012. The S550's V8 was different in prior years as well; from 2007-'11 it was a 5.5-liter V8 good for 382 hp. From 2007-'10, the S63 AMG featured a 6.2-liter naturally aspirated V8 that produced 518 hp. Earlier S65s also had "only" 604 horses.

The fourth generation of the S-Class ran from 2000-'06 and was lighter and sleeker than the massive version that preceded it. Two versions were offered initially, both V8s: the S430 (275 hp) and the S500 (302 hp). The V12-powered S600 (362 hp) debuted a year later, as did the AMG version, the S55 (354 hp). A midcycle refresh in 2003 brought lightly revised light clusters, the availability of all-wheel drive (called 4Matic) and a big boost in power for the S55 and S600 (both rated at 493 hp). A seven-speed automatic came on line in '04. Hitting both ends of the spectrum for 2006, the S350 brought back six-cylinder power (241 hp) while the S65 AMG offered no less than 604 hp.

This model was quite popular and pretty steep depreciation means they are actually quite affordable. In reviews of the time, our editors were impressed by the car's spacious interior and state-of-the-art safety features. Downsides to this generation included a complicated control interface (the COMAND system) and some interior materials that seemed too low in quality for Mercedes' flagship.

Running from 1992-'99, the third generation of the Mercedes-Benz S-Class represented a big step in the ultra-luxury direction. Fitted with dual-pane windows and the availability of V12 power for the first time, this S-Class gained nearly 600 pounds compared to the previous car. Four trims were offered, ranging from the S320 (228-hp inline-6) and S420 (275-hp V8) to the S500 (315-hp V8) and S600 (389-hp V12). If you are considering the purchase of one of these, be forewarned that (as with any complex, high-end luxury vehicle) a clean Carfax report and an impeccable maintenance record are musts.

The S-Class cars of the second generation (1981-'91) were offered in turbodiesel (300SD, 350SD/SDL), inline-6 (300SE/SEL) and V8 (380 SE/SEL, 420 SEL, 560 SEL) versions. This is the generation that introduced cutting-edge safety technology such as airbags and antilock brakes as standard equipment. Perhaps the least desirable of the lot are the 380 series, which made just 155 hp and were prone to timing chain failures. Chances are good that if you find a used 380-series, it will have been retrofitted with a double timing chain. Diesel versions are known for their incredible longevity and it's not unusual to find an example with mileage approaching 300,000 or more on its original powertrain.

  One sweet ride - 2008 Mercedes-Benz S-Class
  By FN SIK - November 24 - 7:53 pm

  This car is absolutely fantastic! Everything about the car exudes quailty and hand built craftsmanship. The touch of the control buttons, the steering, the road grip (with not a hint of body roll at any speed Ive traveled so far) The AMG leather is better than in the 600 and the seat comfort is unmatched with almost limitless adjustments. opperating the many features is easy and nearly intuitive through the command control or one of the redundant feature buttons. I havnt been able to pull the 4.5 sec.0-60 times reported, only able to get it to 6.3 (ironic) but I am not a professional driver and havent managed to time my shifts correctly yet. Either way the car is a blast to drive.

  My Last Mercedes - 1997 Mercedes-Benz S-Class
  By VWRattletrap - November 18 - 10:00 am

  This was the car that turned a certified car nut like myself into someone who just wants cheap transportation. I bought this car new and in the first year had over $10K of warranty work . . . I finally sold it after 12 months and bought a Volkswagen! A partial list: engine torn down to replace timing chains due to constant whine, transmission slip shifting, rattles, radio not connected at the factory, temperature sensor intermittent, damaged paint, and finally, the total arrogance of the factory zone reps!

  The last rock-solid S-Class - 1996 Mercedes-Benz S-Class
  By SRS - October 11 - 10:33 pm

  This car replaced my 84 300SD which I lost in an accident. But having saved my life, I wanted another Mercedes S-Class and decided to try a W140 chassis. It is built like a bank vault and still has all of the hallmarks of a true Mercedes Benz (before the Chrysler merger). It has not been without problems (oil tappet pipe replaced, central locking pump, lower oil pan seal, control arm bushings, steering damper to name a few). But this is a 12 year old car w/ 144K miles. Any automobile that old and with that kind of mileage is going to need attention. So overall, I recommend this car to any Mercedes lover. With proper care and feeding (and a nice "rainy day" fund), you will enjoy it!

  Good Car, Not Thrilled, But Good Car - 2008 Mercedes-Benz S-Class
  By ibitty - September 27 - 3:10 pm

  This is a very beautiful car. Not the best, but nice. Really the best on the market right now, but not sure that says a lot. S550 best of a choice for the current market when compared to the Quattroporte, 7 Series, A8. Cars I wish it came close too, the driving feel and comfort of my 2001 740iL or the elegance of my 2006 Range Rover. I have had it to the shop twice for TPMS and a tire that kept going flat.

  Quality Vehicle with minor problems - 2007 Mercedes-Benz S-Class
  By Cyrus Jan - September 5 - 4:00 pm

  Brakes squeak. Got the pads changed under warranty. Still sqeaking. Dealership says that this is becuase of asbestos being missing as per Federal requirments. Front ends of the suspension rattle when driving over bumps. Dealership says that this is because the car lowers and is supposed to act like that. Other than that, excellent car.

  Not worth the money - 2007 Mercedes-Benz S-Class
  By western6 - July 22 - 12:10 pm

  This is my third Benz, first and last S class. The handling on this car is poor compared to my 05 E class with AMG package. The seats are not supportive in spirted driving. The panorama roof does not have a one touch feature. My old car had an altimeter on the navigation, this car does not. I will most likely will try somthing else next time.

  Im Happy - 2000 Mercedes-Benz S-Class
  By Doc1 - July 3 - 7:23 am

  Ive owned the following , LS400, (2) Q45s Qx4, 528e, Caddys and Lincolns. This my 7th S class Im very happy . it gets plenty of looks and so far in 8 months I put 15k miles on the car. Now Im starting to see little expensive things like transmission seals, control arms, and when we very cold days like below 28 degrees the pump for the suspension stop working.luv the sound system, but it sways a little at high speeds. Ive never driven any other car @ 130 mph. Gas mileage stinks in the city. Nevertheless I plan to buy another one when I can.

  1st time - 2003 Mercedes-Benz S-Class
  By WE-R-1 - June 27 - 8:03 am

  An outstanding auto on the open road. Eye catching vehicle with a smooth and quiet ride, handles well, plenty of cabin room. Been in shop 4 times for power assist problems with trunk (on last trip, power assist doors went on blink as well). Scheduling another appointment- this time trunk will only open with valet key. Noisy front seats remedied after 3rd try with replacement of plastic seat guides. Cup holder design poor. Navigation system- too many key strokes and street info on CD is paltry. Still love the vehicle, but frustrated by the mutiple vists to repair items that I would not expect on a vehicle with less than 32000 miles- let alone a MB.

  First MB - 2006 Mercedes-Benz S-Class
  By TomB - May 29 - 10:00 am

  The S55 AMG was the only MB car I would buy, it has everything I want, but there are some annoyances such as: 1)cooled seats are a joke 2)no touch screen NAV, current unit is out of date 3)dash gauges are boring/outdated 4)key fob remote is IR(short distance) and not radio waves, so I have to go to the drivers door in order to unlock it, then go to trunk to put items in. 5)need to find an independent mechanic, otherwise you will have a miserable time at OEM dealerships, and pay 2-3x more per repair. 6)no back up sensors as standard equip!!, This car is over engineered and exp.
