Model Overview:

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.

  • This Car is No Good - 2007 Mercedes-Benz S-Class
    By -

    When I started driving, it was very uncomfortable. When I got on the road, the car started slipping. Then it stopped slipping. So I went and drove home to my hometown, Chicago, IL. When I arrived, I turned into my street and my back wheel started drifting. It almost crashed but luckily it didt. The fuel in my tank was OK and it was better then my other car. It looks good but i will never rely on that car anymore. As soon as the weather is better Ill go and return the car. It was not ery fun to drive.

  • Fun when it works - 2005 Mercedes-Benz S-Class
    By -

    Great when it works. Fun to drive, quiet, responsive, nice style, but reliability is awful. Electronics are terrible. What a shame. Second Mercedes in a row that was a lemon. It also depreciated from $96,5000 new to under $50,000 in just a little under two years. Stay away! Look at Lexus LS instead.

  • loving the ride...fingers crossed - 2003 Mercedes-Benz S-Class
    By -

    Ive had the car for 3 weeks. It handles GREAT! and the ride is magnificent . Im having a ball using all of the great gizmos (most cabin functions are voice controlled, Keyless go, fully electronic trunk, and much more) Command is not nearly so difficult as the writers say you learn it in a few days. The 4matic, ESP and brake assist already got me out of what could have been a bad skid. My only concern is the occassional bad story of something going wrong with all of that technology, but Im loving the car too much to really think about it. I guess that is what extended warrantys are for

    Great car, you got to experience it.

  • The Paradigm of Luxury - 2008 Mercedes-Benz S-Class
    By -

    I knew the S600 was perfect when I was at my local Mercedes Benz dealership, here in Houston. My wife loved it and the kids (8 and 16) love it also. (My teen girl really enjoyed the vanity mirrors), while it was nearly impossible getting my son out of the reclining rear seats. My wife enjoyed the fact that she could read and drive (I would never commend this action) in stop-and-go traffic due to the very intuitive Distronic Plus System. The COMMAND system was overwhelmingly easy and the car overall was extremely comfortable. I have owned a Jaguar XJ Super V8 and a 2003 Bentley Arnage, but they pale in comparison to this big Benz, due to the way it effortlessly combines luxury and technology

  • Classy S class - 2006 Mercedes-Benz S-Class
    By -

    This is my third S class and continue to love the S class Mercedes. I looked at all the competition and end up returning to the S class for the same reasons why I purchased the previous two cars. The style, quality, service, safety and resale values continue to retain my loyality. Once you have owned an S class you will understand why you will keep buying the most classy car on the road today.

  • S550 coupe - 2015 Mercedes-Benz S-Class

  • Excellent - 2004 Mercedes-Benz S-Class
    By -

    There is a reason this is one of the best cars sold on the planet. Incredible luxury combined with decent economy. It just eats up the road. Just had it serviced at the dealership $220 in total. Not bad for 10,000 intervals.
