The Mercedes-Benz S-Class, formerly known as Sonderklasse (German for "special class", abbreviated as "S-Klasse"), is a series of full-sized luxury sedans and coupés produced by the German automaker Mercedes-Benz. The S-Class is the designation for top-of-the-line Mercedes-Benz models and was officially introduced in 1972 with the W116, and has remained in use ever since. The S-Class is the flagship vehicle for Mercedes-Benz, being positioned above the other Mercedes-Benz models.
The S-Class has debuted many of the company's latest innovations, including drivetrain technologies, interior features, and safety systems (such as the first seatbelt pretensioners). The S-Class has ranked as the world's best-selling luxury sedan. In automotive terms, Sonderklasse refers to "a specially outfitted car." Although used colloquially for decades, following its official application in 1972, six generations of officially named S-Klasse sedans have been produced.
In 1981, the two-door, four-seat S-Class, designated as SEC, was introduced, sharing the petrol V8 engines with its four-door version, W126. After the introduction of a new nomenclature scheme, SEC was simply renamed as S-Class Coupé. For the 1996 model year, the coupé was separated from the S-Class line and named as new CL-Class (in line with other two-door models: CLK, SL, and SLK); however, the CL-Class was reintegrated into the S-Class model line (same with CLK becoming E-Class Coupé and Cabriolet). The first-ever S-Class convertible since 1972, internally named A217, was introduced and became a one-generation model only. After the end of W222 production in 2020, the successors to the C217 coupé and A217 convertible are not planned, citing the low demand for those models and stronger demand for SUV models.




Model nomenclature



The major revision to the nomenclature scheme in 1991 renamed the S-Class with the "S" prefix that has three numbers for engine displacement in "centilitre" with no suffix for fuel type or wheelbase length. The extra information was sometimes affixed to the right-hand side of boot/trunk, denoting the diesel version (TURBODIESEL or later CDI), hybrid version (HYBRID), all-wheel-drive version (4MATIC), AMG, and MAYBACH. The second revision in 2015 allows the suffixes such as d (diesel), e (plug-in hybrid), and the h (mild hybrid) for several years before h was dropped. For 2018 model year, the model designation and AMG and MAYBACH labels switched their position to the left.




Predecessor models






= "Ponton" (1954)

=

The W180 line debuted in 1954, and is the first lineup of "Ponton" models retroactively associated with the Mercedes-Benz S-Class. The W180 featured six-cylinder sedan, coupé, and convertible models, and was produced until 1959. It featured the 220S models (sedan, coupé, and cabriolet) powered by a 2.2L straight-6, and came to ten. The "Ponton" designation referred to its unibody construction, with the era's rounded fenders a stylistic feature on the W180 model.

The "Ponton" lineup included four- and six-cylinder models, but only the six-cylinder W180 line is considered part of the Mercedes-Benz S-Class chronology, as they were the most powerful "Ponton" versions available. The Big "Ponton" model was Mercedes' first without a conventional frame, using a unitized body/frame construction.




= "Fintail" (1959)

=

Mercedes-Benz Fintail (German: Heckflosse) is an informal nickname given to Mercedes-Benz vehicles notable for the presence of tailfins. Though never officially designated as such — Mercedes-Benz claimed they were functional and designated them Peilstege, assisting to mark the end of the car in the rear-view mirror. The Fintail series replaced the Ponton series.
The exterior was designed for the European and North American markets. The W111 was a chassis code given to its top-range vehicles, including four-door sedans, produced from 1959 to 1968, and two-door coupes and cabriolets from 1961 to 1971. The W111, was initially attributed only to six-cylinder cars with 2.2-litre engines. The luxury version with big-block 3-litre engines were given the chassis code W112. The entry-level vehicles with four-cylinder engines were called W110. All three versions W110, W111, and W112, in both two- and four-door bodies, were based on the same unibody structure.




= W108 (1965)

=

The updated and larger W108/W109 model lines were introduced in 1965. The squarish W108 line included the straight-six M129 engine powered 250S, 250SE, 280S 280SE and 280SEL. In 1968 the 300 SEL 6.3 borrowed the 6.3-litre V8 from the W100 600 Pullman to offer a truly high-performance luxury sedan.
During this period, the designation S (for "Sedan") was used for standard carbureted short-wheelbase models; an E (for "Einspritzung", German for fuel-injection) was added to the 250SE, 280SE and 300SE. Long-wheelbase models gained an L (for "Lang", German for "long"), reflecting an extra 10 centimetres (3.9 in) added in the rear passenger compartment. Since the advent of the W108 series, the Mercedes-Benz S-Class has always included two wheelbase lengths, although not all wheelbases are sold in every country.
The more powerful 300SE and 300SEL models were classified as the W109 chassis, with front and rear air suspension (rather than the coil spring based W108 rear suspension), and available burl walnut interior trim, automatic transmission, and power windows.

In 1968, the W108 line dropped the 250SE in favor of the larger-engined 280S and 280SEL; the 250S remained as an entry model until 1969; the 300SE/SEL yielded their 3.0 litre inline-6 for the intermediate SL type (W113) 2.8 litre engine, and were later offered with a 3.5-litre V8 engine (in both the SE and SEL form, not in the U.S.) and 4.5-litre (U.S. only) and 6.3-litre V8 engines (in the SEL model only). The W108/109 lines, which eventually supplanted the W111 lines, were never available with four-cylinder engines.




First generation (W116; 1972)



In 1972, Mercedes-Benz introduced the W116 line, the first to be officially called the S-Class. Produced from 1972 through 1980, the W116 series featured a four-wheel independent suspension and disc brakes. The 280, 350, and 450 (4.5L version) models featured SE and SEL versions. Production of the W116 totaled 473,035 units. This was a groundbreaking sedan for Mercedes-Benz, and for the first time in the company history, the car had an obvious, blatant and outward emphasis on safety placed above a pure styling viewpoint. The overall design incorporated numerous safety features developed from the "safety research vehicles" in the mid-to-late 1960s to the very early 1970s.
These safety features were all newly introduced passenger-car "firsts" on a production vehicle: padded door trim around the windows, heavily padded steering wheel (later to be replaced by an airbag with the Mercedes-Benz abbreviation of SRS standing for the English-language term Supplemental Restraint System), more comprehensive safety padding on the dashboard and around the interior, dual asymmetric windshield wipers, headrests with a center depression to locate the occupant's head in a more central position during a rear impact, a rain-water management system to improve visibility consisting of deep channels on both sides of the windshield and flowing into deeply channeled rain gutters, including similar designs on the side mirrors, rounded body shapes along the edges, such as the tops of the front fenders, etc., designed to ameliorate pedestrian injuries, ribbed rear taillamp lenses which would remain clearer of dirt on the recessed areas, an easy-to-access first aid kit stowed in a recessed compartment on the rear parcel shelf prominently labeled with the universally recognized "cross" symbol which represents "first aid", and several other subtle safety features related to both active and passive safety. The Mercedes-Benz S-Class is a classic chauffeur driven car, and has frequently been used as standard by car hire companies. It is comfortable and safe as well as elegant looking; ideal for drives across the countryside or high class transport on a night out.
The W116 models were large luxury sedans. The W116 was larger on the outside than the W108/W109 series it replaced, but had similar interior capacity, as the additional bulk was driven by several new and aforementioned engineering developments on car safety and occupant protection in a crash. The W116 introduced other improved passive safety features into the vehicle design, including a strengthened vehicle occupant shell. It was one of the first cars to be available with ABS, a driver's airbag supplemental restraint system (but not available at the vehicle's initial launch). Also, the W116 was the first mass production passenger vehicle offered with a turbocharged diesel engine.
The 450SE, then the most powerful model in the W116 lineup, was awarded European Car of the Year in 1974. At the New England Auto Show in 1972 held in the fall season in Boston, the Monroney Label of a 1973 450SE was right at $13,000. 1973 was the first model year of the W116 for the US market. Starting in 1975, the W116 was upgraded with a new fuel injection system to comply with revised exhaust emission standards in European markets. A slight power reduction was a result of this update, but in 1978, a series of further engine upgrades restored original performance levels under the new fuel injection systems. Between 1973 and 1977, 997 Special Edition W116 models were made on order by Mercedes. These cars incorporated stronger body paneling and suspension and was 50 kg heavier than its normal counterpart.




= Engines

=
With the W116 models, the V8-engines of the 350/450 SE/SEL models were now regular options. Due to the oil crisis, fuel efficiency was the major concern for the engineers, yet they still added also the high-performance, limited-production 450 SEL 6.9. This 8-cylinder model, affectionately referred to as simply "the 6.9", boasted the largest engine installed in a postwar Mercedes-Benz up to that time. Every 450 SEL 6.9 featured a self-leveling hydropneumatic suspension, and offered the ABS anti-lock braking system as an option from 1978 onwards. Also, in the United States and Canada only, Mercedes-Benz introduced the economical but powerful 3.0-litre 5-cylinder turbo-diesel OM 617 A producing 85 kW (116 PS; 114 bhp) in 1978, sold as the 300SD.




Second generation (W126/C126; 1979)



The W126 series premiered in September 1979, launching in March 1980 as a 1980 model and late 1980 as a 1981 model in the US and Australia replacing the W116 line. The W126 line featured improved aerodynamics and enlarged aluminum engine blocks. In Australia in 1981, the W126 S-Class won Wheels magazine's Car of the Year award. The W126 was manufactured from 1979 through 1991 with a mid-cycle update. Coupé models based on the S-Class were reintroduced with the W126 (380/500 SEC). Total sales of the W126 S-Class sedans reached 818,036 units, with an additional 74,060 coupes sold.
In December 1980, the W126 introduced a driver side airbag, as patented by Mercedes-Benz in 1971, as well as passenger side airbags (in 1988), seat-belt pretensioners, and traction control. It was the first production car to feature an airbag standard, and as late as 1991 there were only a few other manufacturers in Europe who offered an airbag. The interior featured additional courtesy and reading lamps, along with heated seats and a more advanced climate control system. A four-speed automatic transmission was standard.
Although the top of range Mercedes-Benz 450SEL 6.9 of the previous generation was not directly replaced, the W126 carried forward the hydropneumatic suspension of the 6.9 as an option on the 500SEL. A new cruise control system was offered as well. Succeeding the roadster based coupes, the W126 introduced a two-door variant, the SEC coupé. The W126 S-Class received a mid-cycle update in 1985 that included both exterior modifications and engine upgrades.




= Engines

=
The power plants on the W126 S-Class included straight-6 and V8 engines. Most sales came from the diesel model in Europe and straight-six models in the United States, although the V8 models were praised by contemporary journalists. The US initially received only the smaller of the two V8 engines, the 3.8 litre, which turned out to be a disaster, both due to timing chain repair issues, and to being severely underpowered, with 0-60 mph (97 km/h) acceleration in a leisurely 11 seconds and a modest top speed of 117 mph (188 km/h). The 5.0 litre engine was far more capable, with 0-60 mph (97 km/h) acceleration in 7.3 seconds and a top speed of 138 mph (222 km/h). During the W126 mid-cycle update in 1986, both the straight-6 and V8 engines were upgraded in several models to different displacement levels (six-cylinder upgraded from 2.8 L to 3.0 L, eight-cylinder upgraded from 3.8 L to 4.2 L, and 5.0 L to 5.6 L).




Third generation (W140/C140; 1991)



In 1991, the W140 series replaced the W126 line with the first production model assembled in April of that year. The W140 grew in proportions and featured two wheelbase lengths and a shorter-wheelbase W140 coupé. Production totalled 432,732 units.
The W140 cost 25% more than the W126 that it replaced and featured double-pane window glazing, self-closing boot lid and doors, electric windows with a jam-protection feature (lowering when encountering an obstruction), rear-parking markers in the US (which appeared on the rear wings when in reverse), and a heating system which emitted warm air while residual energy was available after the engine was turned off.
In 1993, Mercedes-Benz model nomenclature was rationalized, with the SE/SEL/SEC cars becoming the S-Class and alphanumerical designations inverted (e.g. both the 500SE and 500SEL became S500 regardless of wheelbase length). In 1995, the W140 received a minor face lift featuring clear turn signal indicator lenses on the front and rear as well as headlamps fitted with separate low- and high-beam reflectors for the US market. Following the mid-year face lift, the W140 coupe and sedan (Saloon) featured Electronic Stability Control. The W140 is heavily referred to or nicknamed as the Mercedes "Shabah/شبح" (Meaning "ghost" when translated) in many Middle Eastern countries.




Fourth generation (W220; 1998)



Mercedes-Benz presented the W220 in July 1998, marketed as a sedan, only. Despite being smaller than the previous generation, the W220 offered more interior space. Production of the W220 totaled 485,000 units.
The W220 introduced air suspension, marketed as Airmatic, as well as a navigation system with center console-mounted screen display, along with its input control system, marketed as COMAND. Other options included keyless entry and ignition, a radar-controlled cruise control system marketed as Distronic and a cylinder shut-off system marketed as Active Cylinder Control. The all-wheel drive system was introduced to the North America market S-Class for 2003, and marketed as 4MATIC.
Consumer Reports classified the W220 model's reliability as "poor," its lowest rating, and called it one of the "least reliable luxury cars;" Edmunds gave the S-Class a 5 out of 5 reliability rating; and MSN Autos gave a rating of 9.0 out of 10. By March 2011, Consumer Reports revised its reliability ratings for the 2001 and 2002 S-Class to "average". Forbes described the W220 S500 as "built remarkably well." Early W220s in 1999 were recalled for issues with the trunk spring and the hydraulic fuel line; there were no recalls for the 2005 or 2006 model years.
In 2002, Mercedes-Benz introduced the world's first preemptive safety system on the W220 with a system marketed as Pre-Safe. The W220 received an exterior refresh with updates to the front fascia. The grille angle was adjusted to a slightly more upright position, and the xenon-discharge headlamps were given a new transparent housing, replacing the earlier opaque versions. The front bumper's lower air intakes were also restyled. In 2005, the S-Class was the first vehicle to receive a TÜV Institute environmental certificate from the German Commission on Technical Compliance for environmentally friendly components.




= Engines

=
The W220 was available with more engine options than the W126 or W140. The range started with smaller 2.8 (Singapore) then 3.2L 165 kW (224 PS; 221 bhp) V6 motor, which was superseded by an enlarged 3.7 L 180 kW (245 PS; 242 bhp) V6 in the S350. The S430 was powered by a 4.3 L 205 kW (279 PS; 275 bhp) V8 and the S500 was powered by a 5.0 L 225 kW (306 PS; 302 bhp) V8. The S55 AMG was outfitted with a supercharged 5.4 L 368 kW (500 PS; 493 bhp) V8 motor, the S55 AMG 2000/2001 was outfitted with the naturally aspirated 5.4 L 265 kW (360 PS; 355 bhp) V8 motor. The S600 was outfitted with a 5.5 L 368 kW (500 PS; 493 bhp) M275 V12 biturbo engine, the S600 2000/2001 was outfitted with the naturally aspirated M137 5.8 L 270 kW (367 PS; 362 bhp) V12 engine.
In 2001, Mercedes produced a very rare S 63 AMG with a 5 speed automatic transmission and a modified version of the M137 V12 engine (displacement went up from 5.8 to 6.3 litres, 6258 cc) making 438 bhp (444 PS; 327 kW) at 5,500 RPM, and 457 lb⋅ft (620 N⋅m) of torque at 4000 RPM. 70 examples were manufactured and marketed in Europe and Asia.
In 2003, Mercedes debuted the S 65 AMG, powered by a biturbocharged 6.0 L (5,980 cc) M275 AMG V12 engine and a 5 speed automatic transmission, it produced 604 bhp (612 PS; 450 kW) at 5100 RPM, and 999 newton-metres (737 lb⋅ft) of torque at 4000 RPM. Acceleration from 0 to 100 km/h (62 mph) was officially rated at 4.4 seconds (0 to 60 mph (97 km/h) in 4.2 seconds), and the car was limited to 250 km/h (155 mph).




Fifth generation (W221; 2005)



The W221 was introduced in the autumn of 2005 at the Frankfurt International Motor Show, with sales starting in autumn of 2005 and export to other markets beginning in 2006. Again there was a big change in design. The W221 S-Class made its North American premiere at the 2006 North American International Auto Show in January. The W221 is slightly larger in all dimensions than its predecessor, and it features three newly developed engines with up to 26% power increase. The interior is completely new, all materials have been upgraded and make for a more luxurious ride, and the center console transmission gear lever has been replaced with a column-mounted shifter. New technological features on the W221 include an infrared Night View Assist feature and the latest Mercedes-Benz pre-collision system. The W221 features sharper exterior styling (most notably wide fender arcs) and technological improvements. The W221 is the second consecutive generation of the S-Class to be solely produced in a sedan body style.
Models sold in North America are the S450 (2008– , SWB and Canada only), S400 Hybrid (2010– ), S350 Bluetec 4MATIC (2012- ), S550, S600, S63 AMG and S65 AMG; other models to be sold outside North America include the S280, S350, S300, S420 CDI and S320 CDI. The first W221 model released in North America and Japan was the S550 (called S500 outside North America), with the S600 arriving in the following spring.
In the US for the 2010 model year, the S-Class received a facelift across the entire model line in mid-2009, with a new S400 Hybrid version. Daytime LED running lights were fitted to the outer edges of the bi-xenon lamp units. The rear end was accented with a total of 52 distinctively arranged LEDs in the two taillights. Gone are the body-coloured strips through the tail lamps. Other noticeable changes at the front of the car are a more pronounced arrow-shaped grille, a new front bumper with a light-catching contour, and a chrome strip below the cooling air intakes. New, sleeker rear-view door mirrors with LED turn signals were also added. The exhaust tailpipes of all S-Class variants were visibly integrated into the rear bumper. The wheels were updated to more modern-style ones. Safety is also improved on most Mercedes-Benz models with the orange-coloured light reflectors mounted on the sides of the bumpers. The C-Class look at the front is removed. Some shiny chrome is added to the bottom of the doors and bumper.
In terms of performance, the S550 completes the 0–100 km/h (62 mph) run in just 5.4 seconds. Despite weighing 2,304 kg (5,079 lb), the S65 AMG still makes 0–100 km/h (0–62 mph) in just 4.2 seconds. The S600 makes the same sprint in about 4.6 seconds.

The brakes continue to become more advanced with the new Brake Assist Plus system monitoring for an impending collision and increasing braking if needed, while the Distronic Plus radar-guided cruise control can now bring the car to a complete stop. This system works in outdoor conditions; a test demonstration by Mercedes-Benz in a crash-test hall resulted in embarrassment for the company when a new S-Class crashed into the back of a stationary W220 S-Class. This incident was later attributed to the radar system malfunctioning inside the radar-reflective (i.e. radar-confusing) steel test building where the event was filmed.
Upscale department store Saks Fifth Avenue offered 20 special-edition S600 sedans for sale in its 2005 Christmas catalog. All 20 cars, priced at US$145,000 each, were sold on November 22, 2005, in under seven minutes. The Saks-edition S600 sedans were finished in a mocha black exterior with an almond beige interior and were the first examples of the S600 to be sold to private owners. The S600s came with nearly every option standard. In 2007, Automobile Magazine named the W221 S-Class as one of its 2007 "All-Stars" over rivals from Lexus and BMW, and Car and Driver selected the S550 as the winner in a five-way comparison test of flagship luxury sedans, as did Motor Trend Magazine in July 2009 in a three-way comparison test, with the other two competitors being the BMW 750Li, and Audi A8L 4.2 Quattro. The W221 S-Class was also the recipient of several other motoring awards (see following).




Sixth generation (W222/C217/A217; 2013)



Officially unveiled in May 2013, the new S-Class has a more streamlined appearance than the outgoing model. Some interesting features include a large front grille inspired by the F700 Concept car and LED lights used exclusively inside and out — a first in the automotive industry. Two strong converging character lines give the flanks a more sculpted look, while integrated exhaust tips and a large glass roof (likely optional) highlight the design.
Along with the sedan, the S-Class spawned a coupe (Mercedes-Benz C217) and convertible (Mercedes-Benz A217) as well as an extended-wheelbase 'Pullman' variant, longer than the long-wheelbase 'L.' While the short-wheelbase model carries chassis code W222, the long-wheelbase model uses chassis code V222. Unlike previous generations, Mercedes focused primarily on the development of the longer model as many customers in the fast-growing Asian markets prefer to be chauffeured. In 2016 Mercedes W222 was the last car with an S65 AMG engine.




= Equipment

=
Inside, almost every surface is covered by a 'luxury' material – everything that looks like leather is genuine leather, and metal is used rather than any plastic alternative. The instrument cluster consists entirely of two widescreens (30.5 cm diagonal) LCDs with animated graphics. A 'Head-Up' display and gesture-responsive touchpad became options in early 2014. It featured a new infotainment system.
The W222 debuts the available Magic Body Control, consisting of windshield-mounted stereo cameras that can 'read' the road ahead (Road Surface Scan) and communicate with the Active Body Control suspension to ready it for an uneven road surface. Initially available only on 8-cylinder models and above, Magic Ride Control attempts to isolate the car's body by predicting rather than reacting to broken pavement and speed humps.
Available luxury appointments over and above what was offered in the W221 include a choice of massage type for each seat occupant (the W221 offered various intensities of a single massage type) and two levels of premium audio from the luxury German brand, Burmester.
The W222 has driver assistance systems aboard that allow it to steer a course within a lane and follow a leading vehicle for a short period (DISTRONIC PLUS with Steering Assist, also called traffic jam assistant). It will also slow or come to a dead stop and accelerate in response to traffic ahead. Mercedes engineers claim to have, under controlled conditions, ridden aboard a W222 S Class that has driven autonomously for 50 km, merely by altering parameters controlling equipment already fitted. Such modifications are not available to the general public.




= Powertrain

=
Like the W221 S500, the W222 S-Class is powered by a more powerful twin-turbo V8 producing 455 hp (339 kW) while the S600 will carry a twin-turbo V12. There is also a diesel-powered S350 BlueTEC version, a hybrid S400 with a 20-kilowatt (27 PS; 27 hp) electric motor and 228 kW (310 PS; 306 bhp) V6 engine, a diesel-electric hybrid S300 BlueTEC. An S500 Plug-in Hybrid was later introduced at the Frankfurt Motor Show (IAA) with a market release in 2014 and claimed a 3 L/100 km (94 mpg‑imp; 78 mpg‑US) mileage, a CO2 rating of 69 g/km (3.9 oz/mi) and up to 30 km (19 mi) of emissions-free driving. The S500 Plug-In hybrid is fitted with a 245 kW (334 PS; 329 bhp) 3-litre V6 and an 80-kilowatt (110 PS; 110 hp) electric motor. AMG fettled S63 (V8 bi-turbo) and S65 (V12 bi-turbo) LWB sedans are also on offer. All S-Class models will come with a 7-speed automatic transmission.




Seventh generation (W223; 2020)



The W223 was unveiled on 2 September 2020. This generation will not feature a coupe or convertible model as they will instead be replaced by the next generation AMG GT and SL-Class models respectively. The interior of the new model includes up to five displays, augmented reality head-up display and an ambient lighting system. Additionally, the W223 S-Class is the first car in the world to come with rear seat airbags that work by using gas to inflate supporting structures to deploy a bag that fills with ambient air, instead of conventional fully gas-inflated airbags that are widely used in automotive airbag systems. On 5 December 2022 Mercedes-AMG has debuted the S 63 E Performance V8 PHEV with 802 HP.




Engineering


Mercedes-Benz has been able to exploit their perceived engineering know-how as a marketing tool, culminating in its one-time slogan, "engineered like no other car in the world." This slogan was used throughout the 1980s with the marketing of the W126 S-Class. However, following the formation of DaimlerChrysler and the cessation of engineer-sanctioned overbudgeting in the late 1990s, this slogan was dropped. The subsequent W220 model S-Class was reported to suffer from relatively lower reliability and quality rates than previous models. However, ratings have been improving since the W221.




Concept cars



In the 1980s, Mercedes-Benz built the world's first driverless cars using the S-Class, together with the team of Professor Ernst Dickmanns at Bundeswehr Universität München. The culmination of this effort was achieved in 1995, when Dickmanns' re-engineered autonomous S-Class robot completed a trip from Munich, Bavaria to Copenhagen, Denmark and back. On the autobahn, the robot S-Class achieved speeds exceeding 175 km/h (109 mph). It suggested and executed overtaking maneuvers. The car's abilities left a big impression on many observers and are said to have heavily influenced robot car research and funding decisions worldwide.
A concept future hybrid, the F700 research car, was also unveiled at the 2007 Frankfurt Motor Show. The F700 featured three regular opening doors and a fourth door capable of 180-degree rotation. The concept also featured bulletproof and puncture-resistant tires.




Safety


Mercedes-Benz has traditionally introduced its safety innovations in the S-Class. For instance, the S-Class was the first car in Europe to incorporate airbags. S-Class safety features included innovations in active safety (accident avoidance), passive safety (collision protection), and holistic safety (integration of both active and passive safety features). Active safety features include: ABS braking in 1978 (acts to reduce braking distances and improve stopping control; co-developed with Bosch); traction control and Electronic Stability Program (ESP) in 1995 (improves driver control during difficult road conditions); and Brake Assist (provides full braking power during emergency stops). In 2005, a new infrared night vision feature was introduced (improves visibility during nighttime conditions). Despite the popular misconception, the S-Class was not the first car fitted with ABS braking technology, although some credit can be given for popularizing this now largely standard feature (ABS was initially an option on most models of the W126 S-Class). Active lane keeping became standard in 2011.

Passive safety features include: crumple zones in 1957 (vehicle body structure absorbs the force of impact); collapsible steering column (prevents the steering column from protruding into the cabin during accidents), strengthened occupant cell enhanced occupant protection during severe impacts (rollovers); pre-accident seatbelt tensioning (tightens seatbelts prior to impact), and sandwich platforms (allows the engine to slide under the occupants in a head-on collision).
PRE-SAFE, Mercedes-Benz's holistic safety feature, was introduced on the S-Class in 2002. PRE-SAFE integrates multiple active and passive safety features for a "safety net" approach to vehicle safety by attempting to prevent accidents; if accidents do occur, PRE-SAFE aims to reduce occupant injury. In the latest version of this pre-collision system, PRE-SAFE will prime the brake assist system, lock the doors to prevent accidental opening during the accident, adjust the seats, close the windows and sunroof, and tighten seatbelts during certain types of collisions. In the event an accident results in a rollover, the PRE-SAFE feature unlocks the doors and lowers the windows approximately 1 cm (1⁄2 in) to allow you to exit or safety workers to gain access easily.
Rear seat airbags are a world-first and will be introduced on the W223. In addition, E-ACTIVE BODY CONTROL is available for the first time on an S-Class.

A special armored version of the Mercedes-Benz S-Class has been produced, known as the S-Guard. Features include the capability to withstand small arms fire and certain explosive devices, a self-sealing fuel tank, and an alarm system.
In 2009, Mercedes-Benz launched a long-wheelbase version of the S-Guard, known as the Pullman Guard. This model is 45 in (1,100 mm) longer than the standard model. It also has a higher roof and a taller rear window, with a different rake. The Pullman Guard is also available in the W222 and the W223.
The S-Guard is widely used at the diplomatic level to protect world leaders. Ninety governments worldwide are known to use the S-Guard for the transport of government leaders and dignitaries. The S-Guard is built on a special production line at the S-Class facility in Sindelfingen, Germany, with specific S-Guard enhancements integrated at multiple stages throughout the production process.




Production


Most S-Class models, including the W221, are built at the Daimler AG plant in Sindelfingen, Germany, and the Mercedes-Benz-Valdez plant in Santiago Tianguistenco, Mexico. Founded by Daimler Motoren Gesellschaft in 1915, the Sindelfingen plant also produced the model 600 "Grosser Mercedes" and past generations of the S-Class. Previous S-Class models (such as the W126) were built in different locations ranging from Stuttgart to South Africa, but with recent models (such as the W220) production has been concentrated in Sindelfingen and Santiago Tianguistenco. In February 2007, DaimlerChrysler Malaysia's (now, Mercedes-Benz Malaysia) plant in Pekan, Pahang began production of S350 (model W221) vehicles and is currently assembling S300, S350L, and S500L. In all, some 2.7 million S-Class vehicles have been produced in the past forty years.
