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.

  What a treat - 2007 Mercedes-Benz S-Class
  By DoubleT - October 4 - 2:50 pm

  The new S550 is quite a change from the previous S500. Much more luxurious, but faster, better road feel and better fuel economy. Best car I have had. Only time will tell about reliability. Got mine with special seats, keyless and 19" wheels. The I- drive does it right (intuitive like the Audi, not awkward like the BMW) Intuitive (unlike the BMW) and easy. Nav system is simple to use. Voice activitated controls extensive and it learns your own voice. Really works and is once, again easy.

  repair-a-month - 1995 Mercedes-Benz S-Class
  By Eminem - October 2 - 10:00 am

  Excellent driving and looking car, very comfortable, but no fun to maintain. The front brakes wore out twice on me ( in 16k miles), and I was trying to make them last the second time around ( using factory pads you only get about 8k ) Other problems in 6 months: Water pump, sensor, air conditioning leak, antenna, and some engine rough problem that was fixed with new expensive plugs. Notice all the repairs were minor, but even minor stuff is expensive on this car. If you have money to burn on maintenance, than its a dreamy car to drive ( its huge and heavy yet quick and handles well ). I just wish is was as reliable as a japanese car.

  Best 6cyl car in America - 2006 Mercedes-Benz S-Class
  By Melvin Norman - October 1 - 9:40 am

  This is my 4th "S" class Mercedes. I have owned Jaguars, Lexus, Cadillacs in the past 20 years. I went back to Mercedes when the 6cyl S Class became available again. This car has plenty of power, no need for an 8cyl. The sound system is superb. Leather quality is lacking, would like to see a 10 disc CD changer rather than the 6. All around excellent car, fun to drive.

  Mercedes Critic - 2002 Mercedes-Benz S-Class
  By Walter Haynie - September 18 - 6:20 pm

  I purchased the 2002 S500 for my wife as a Christmas present. She just loves the vehicle, apperance, handling, and quality of the vehicle. We compared other brands the were 4-5 years old and the quality just did not compare to like new look of the Mercedes quality. My wife constantly comments on how she loves driving "her" Mercedes. This is probably the best thing that I could have done for my wife, (and myself ha,ha) The Mercedes makes her feel better about herself and gives her confidence with the prestige of the Mercedes Benz name. We even purchased a Dog and named her Mercedes Ashley Haynie, what could be better? Loving life with Mercedes Benz and being a proud owner of the S500.

  This car has everything - 2008 Mercedes-Benz S-Class
  By tallyken - September 13 - 3:03 pm

  Is it possible to have luxury, comfort, superb build quality, and safety in one car? Yup! Oh, you want performance too? Well, this is the one to get. Im comparing the S63 to other cars Ive owned: NSX, SL600, 2 Vipers, several Corvettes, S500, SL55 AMG, and the S63 rules.

  Bye Mercedes - 1995 Mercedes-Benz S-Class
  By cuperqui - September 9 - 10:00 am

  I have owned a mercedes for 25 years to include various classes. The S-class was the ultimate car. You feel very much in control of the car. Long highway drives are effortless. However, purchase a good extended warranty. Power windows mechanism have gone out on two windows in my S-class, gasket and seals have been replace twice, the illumination of dashboard components have gone out twice and maintence and repairs are expensive. I recently moved to a Lexus 430 and admittedly I miss my Mercedes drive but the Mercedes pails in comparison to the luxury features of my Lexus and the reliability of the Lexus.

  The S63 is the best combination of comfort and speed in one machine - 2008 Mercedes-Benz S-Class
  By riosouza - September 4 - 9:25 pm

  The S63 is the best combination of comfort and speed in one machine, period. It has so much power on "S" mode that if it wasnt for the traction control it would be hard to keep it straight. Its like being on a Cadillac with the feeling of a high end sports car when you hit the gas pedal. I drive my S63 daily, and the comfort makes me slow down and enjoy the ride. Then when I got an idiot tailgating me, I just hit the gas for few seconds and he disappears on my rear view mirror. If you go for a test drive, you will buy it...

  Gliding in comfort - 2002 Mercedes-Benz S-Class
  By fredkimka - August 29 - 2:00 am

  Consumer Reports says this is the best riding car they have ever tested and they are absolutely correct. It is a pleasure to drive and shines on long trips. Despite a few reports of quality or reliability concerns, my vehicle has been 100% trouble free. Ive had it nearly a year and it has never needed service.

  Exceeds Expectations - 2004 Mercedes-Benz S-Class
  By HoustonDriver - August 22 - 2:00 am

  Driving a 98 S500 for a number of years was a lot of fun, but nothing compared to the 2004 S430. More power than the old S500, better handling and a load of features make my new Benz an absolute pleasure to drive.
