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.

  Unlike any other - 2003 Mercedes-Benz S-Class
  By Zachmbenzfvr - July 12 - 2:00 am

  Having owned this car for about three weeks I can say that it is one of the best if not the best Mercedes I have ever owned. I have not experienced any problems with my car at this moment. This car is very spirited and I only wish I would have put my name on the list for the s600. This thing is quick as it is, with 100+ more horsepower, this car would be a rocket. But oh well, My baby is just fine the way she is.

  S500 2004 - 2004 Mercedes-Benz S-Class
  By Will - July 10 - 2:06 pm

  Ive had this car almost 2 years. No issues. S500 engine with 7 speed transmission is like silk with rocket take-offs when passing on highways. 20-24mpg on hwy / 18-20 avg combined. Mercedes has addressed quality issues which were apparent during the 1990s. Ive had a 2000 E320 and the 2004 S500. Both cars have been issue - free and low maintenance while a pleasure to drive. Nice curb appeal was well for business.

  The Best of the Best - 2003 Mercedes-Benz S-Class
  By Steebie - July 6 - 2:00 am

  This is my second S430 in three years, and the 2003 has really improved, especially the command system. The trunk pop out handle allows you to close the trunk without one fingerprint on the finish. Sound system is the best of the best, and comfortable ride cant be beat. The 2003 is the best yet.

  S550 a Winner - 2007 Mercedes-Benz S-Class
  By BobObO - July 4 - 4:43 am

  Initially, I wasnt too excited about the exterior look from the pictures, but it grew on me once I saw the actual car. After sitting in it on the date of the delivery, I was convinced that it is a definite success. I have a 745Li, but the fit and finish on the S550 is definitely warmer and more sophisticated then the BMW. Driving it was heavenly, with the 7 speed transmission and the 382hp, the car was silk smooth. I also got the ABC suspension a $3900 option, and I was worth every penny. ABC on S550 is almost the same as the Maybach suspension. Although many criticized Mercedes for its COMAND center being too much like the BMW iDrive, the COMAND is soo much easier and faster. S550 a winner

  The Best Car Ever - 2005 Mercedes-Benz S-Class
  By Ryan Jennings - July 3 - 2:20 am

  I recently bought this new S-class 500 at Atlanta Classic Car and it was my most enjoyable buying experience. Mercedes knows how to treat its consumers right. I love this car it has a strong engine and the technology is amazing. The safety aspect was one of the reasons I bought this car. It has the Pre-Safe system and 8 different airbags. The seats are very confortable and it can make you feel as if you were riding in a limo. Love the Car. If your in the market for a quality and powerful luxary sedan, the Mercedes should be your fist choice. Love this car!

  2003 S Class - 2003 Mercedes-Benz S-Class
  By Hawk1 - July 1 - 10:00 am

  Magnificent car in every respect except reliability!! The vehicle was delivered to me with no refrigerant in the air conditioning system. It required service to charge the system within the first week of ownership. No leaks were detected by the service technician. Seven weeks later the AC failed again. The system maintained the charge, but another component of the AC system failed. Parts are on order but this means another trip to the service department--three within the first two months of ownership.

  Cool but unreliable ride - 2004 Mercedes-Benz S-Class
  By Joe Huflin - June 13 - 4:53 pm

  This car has all you would expect for its money, and then the roof rattles some, the tire pressure monitors keep tripping and failing, the battery is flat after a 2 week business trip. Should not happen for this kind of money. No space for a cell phone, cupholders are a joke, and you forget all that when you hit the throttle and slide over the freeways, but then it all comes back at a traffice light. Great ride, classy car, but I am cured for life trying to put money on the table to buy such a set of wheels new, ever. I am soar but still OK, will enjoy it a few months more, but never buy this car new. What a shame for a handmade Mercedes, I lost a lot of faith in MB.

  TestedBMW&Lexus - 2002 Mercedes-Benz S-Class
  By TestedBMW&Lexus - June 6 - 10:00 am

  Made a deposit on BMW 745Li over one year ago. When the new BMW came out I was very impressed with acceleration, handling, and braking, but interior weirdness and exterior styling turned me off so that I passed on my custom ordered car when it arrived. Ive bought four BMWs in the past. Tried Lexus and Mercedes. Bought the Mercedes and love it so far. BMW could have had a great, no wonderful, car but somone overdosed on caffeine when they designed the exterior and the truly crazy overengineered controls. Delighted with the Mercedes.

  By makandari - May 28 - 5:10 pm

  I purchased a 1005 Mercedes-Benz S430 and am very pleased with it. i have not had any problems with it so far.no problems. It has been very reliable and safe. I am waiting for the 2006 S-class. When you drive a Mercedes you do not want to drive any other car. It is king of the road.
