More concentration when working, greater relaxation


Five different rear seat variants make it possible to configure the rear of the S-Class as a working or rest area. One new feature is the heatable additional cushion for the head restraint, which is available for the two electrically adjustable rear seats. The adjustment range and angle of the front passenger seat in the chauffeur configuration and the reclining seat behind it have been improved as well.

An overview of the five rear seat variants:

Two-seater with electrically adjustable single outer seats and Business centre console (First-Class rear)-O

S = Standard, O = Optional, - = not available

An adjustable and heatable additional cushion on the head restraints is a new feature for the outer single seats. This uses an integrated heating membrane to give pleasant warmth in the occupant's head and neck area. The heating function is activated via the seat heating. The power is conveniently and safely supplied via the push buttons of the removable cushion. The additional cushion is included in the Rear Seat Comfort package.

With the Chauffeur package (available for the S-Class with long wheelbase), the driver and front passenger can electrically move the front passenger seat to a chauffeur position. The adjustment range and angles of the front passenger seat and the reclining seat behind it have been improved in various respects: Thanks to a modified head restraint, the front passenger backrest can be folded further forward by 26°, the larger heel support has 10 millimetres more travel and, as in a train, can also be folded down as a footrest. The adjustment range of the calf rest on the Executive seat has been extended by around 50 mm compared to the previous version.

The active multicontour seats, additional warming cushions and the 8-way luxury head restraints go together to form the Rear Seat Comfort package. If single active multicontour seats are ordered, the side bolsters of the backrest and the contour in the lumbar area can be adjusted to suit the individual body shape of the occupant. A massage function is also available. The massage programmes for the rear seats include: Classic Massage, Workout back and Wave massage. The massages are also available as part of ENERGIZING comfort.

If the First-Class Rear (rear centre console) is specified, the front console is visually continued on the propshaft tunnel. Two thermo-cupholders are integrated to warm or cool drinks as required. New features include a tray for the MBUX rear tablet, a black-panel surface ahead of the armrest and four USB-2 connections. The stowage tray below the armrest holds a wireless charging system for mobile phones and the receiver for car/business telephony. Similarly to an aircraft seat, the centre console optionally comes with two tables which can be easily folded in or out with one hand.

The Executive seats in the rear feature the seat cushion airbag. The airbag is located under the seat cushion upholstery, but on top of the plastic seat shell, which is moved by the seat mechanisms. This means that the airbag is always in the right position relative to the occupant. In an accident, with the occupant in a reclined position on a flat seat cushion, without additional measures there would be a danger of the pelvic area sliding beneath the belt strap (submarining). This can be prevented by the cushionbag, as it raises the front section of the seat cushion upholstery. The airbag is only activated if the seat is in the reclined position during a crash. It is not activated in the upright position, as there is then no danger of submarining.

If the Burmester® high-end 4D surround sound system is specified, two exciters are also integrated into each outer rear seat. With the optional seat climatisation there are four radial fans in the cushion and two in the backrest of each seat. The air taken in through the perforated seat cover flows through the seat structure and is vented downwards and to the rear. This surrounds the occupants with a pleasant flow of air. In conjunction with electrically adjustable rear seats, as part of the Warmth Comfort package, surface heating for the armrests with three-stage adjustment is also available in the rear.
 
Multi-dimensional musical enjoyment


There is a choice of three sound systems in the new S-Class. The two Burmester® systems provide multi-dimensional surround sound. 3D Surround Sound is created with the help of special Burmester® algorithms and two loudspeakers integrated into the headlining. Active actuation of each speaker by digital technologies produces an exceptionally expressive and natural sound. The Burmester® high-end 4D surround sound system adds another dimension to the three-dimensional listening experience – 4D sound. This uses exciters to transfer resonance to the seats. In combination with the two Burmester® sound systems the S-Class has in-car communication. This comfort function assists communication between the occupants during a journey.

Here is an overview of the three sound systems:

30 speakers and eight exciters are included in the Burmester® high-end 430 D surround sound system. Two exciters are integrated into the backrest of each seat. Direct reproduction of the sound resonance in the seats adds another level to the three-dimensional listening experience – 4D sound. The perceived intensity of the sound can be individually adjusted for each seat. The music becomes even more emotional thanks to this feelable component. In addition to playing music, the 4D sound is used for an even more emotional function of ENERGIZING COMFORT (see corresponding chapter).

Speakers integrated into the front seats at ear level make an even further improved surround sound experience possible for all occupants. With the new drivertainment function, information from the infotainment system, e.g. navigation instructions and telephony, can be specifically directed to the driver's seat. With sound personalisation, the user can easily adapt the sound system to suit personal listening preferences. The result is saved to a personal sound set and stored in the user profile.

Two amplifiers with a total output of 1750 watts power 37 separately processed output channels. Hybrid amplifier technology with digital signal processing, analogue filters and separate power supply ensure precise and highly dynamic sound reproduction. Alongside the acoustic attributes, features such as the extending tweeters in the mirror triangle or the lighting are another highlight of the high-end sound system.

The S-Class has the in-car communication function in combination with the two Burmester® sound systems. This function makes communication between the occupants more comfortable by amplifying speech and transmitting it from the speakers. In the new S-Class Saloon, amplified speech is supported in two directions, from the driver/front passenger to the rear passengers and vice versa.

The intelligent signal processing separates voice signals from surrounding noises. The voice signals are amplified, the surrounding noises suppressed. This voice amplification takes the interior noise level into account, and dynamically adapts the amplification of the voice signals.
 
Whether warm or cold: just feeling good

The climate control system is a completely new development. Improvements have been made to the acoustic properties, air quality in the interior and ease of operation and control in particular. Both the maximised cooling output and the heat output are highlights. For maximum comfort on cold days, all models with petrol engines have a 48 V PTC (Positive Temperature Coefficient) booster heater as standard. This heats the interior especially rapidly, and a warm outlet air temperature can be felt at once. Thermotronic with two climate zones is standard equipment, with 4-zone Thermotronic in the rear as optional equipment.

The two climate control systems share a number of other functions. For example:

  • 7 personal climate profiles can be stored, plus a guest profile.
  • Automatic switching to air recirculation when approaching a tunnel, and when the air quality sensor detects poor outside air quality. At the same time all windows and the sunroof are closed – then returned to their previous positions when switching back to fresh air. They are also closed if the air recirculation switch is pressed for longer than two seconds.
  • Residual engine heat utilisation
  • 2 solar sensors (in the rain sensor and on the parcel shelf)
  • The window misting sensor in the stem of the rear-view mirror measures the window temperature and the interior humidity level. The humidity level of the intake air is also assessed. This enables the energy requirement of the compressor to be reduced in cool temperatures with dry ambient air. Energy is saved, and too dry interior air is avoided.
  • 5 sensors for the outlet air temperature (Thermotronic Rear: 4 plus 2 heat exchanger sensors)
  • 2 interior temperature sensors
  • 17 step adjustment motors to control the temperature and airflows (Thermotronic Rear: 20)
  • With ENERGIZING AIR CONTROL, Mercedes-Benz offers its customers a high-quality filter system that removes particles and pollutants from the air. This uses an innovative particle filter with activated charcoal to reduce fine dust, pollen and odours.
  • Electric refrigerant compressor (in combination with petrol engines)

AIR-BALANCE package: active fragrancing and ionisation

The preceding series was the pioneer, and active fragrancing has now become a popular feature for the high-end Mercedes-Benz model series. As part of the AIR-BALANCE package, the intensity of the fragrancing can be set in three stages. Two special fragrances were created for the new S-Class: BAMBOO MOOD is an unobtrusive, light fragrance full of power and energy. Bamboo is rounded off with a hint of fresh water. COTTON MOOD is an atmospheric fragrance conveying purity and freshness. A touch of ozone conveys this first impression. A hint of green and jasmine accentuate this calming effect. Amber and musk form the basis for this fragrance.

An ioniser is integrated into the side vent in the dashboard. This ionises the air in the duct with a high voltage.

Bright, variable and innovative

The previously optional MULTIBEAM LED is now the standard headlamp for the S-Class. As well as variable control of low and high beam, it also features Adaptive Highbeam Assist Plus. The optional DIGITAL LIGHT system enters series production for the first time at Mercedes-Benz. This allows completely new functions,
e.g. the projection of guidelines or warning symbols onto the road ahead.

In the MULTIBEAM LED headlamp, a light module with 84 LEDs arranged in three lines creates a grid in the form of a matrix. With this arrangement, not only the light distribution of the high beam but also that of the low beam is freely configurable and technically precise. MULTIBEAM LED therefore allows different light functions to actuate independently.

Digital Light: high-resolution light projection with new functions

In each headlamp, Digital Light has a light module with three extremely powerful LEDs whose light is refracted and directed by 1.3 million micro-mirrors. The resolution is therefore more than 2.6 million pixels per vehicle. The micro-mirrors occupy the same area as a thumbnail. A control unit with a powerful graphic processor uses an HDMI-like connection to generate a continuous video stream to the mirrors. Digital Light therefore uses the technology of video projectors. This innovative headlamp in the S-Class can be recognised by its concave lens, the lettering and shining blue floor facing.

The beam divided into 1.3 million pixels makes absolutely precise light distribution possible. It makes Highbeam Assist over 100 times more precise then 84-pixel light when excluding oncoming traffic or road signs from the light beam. Light/shadow graduations and the light distribution of all the other adaptive light functions are also realised with considerably more precision, optimising illumination by e.g. fog light, motorway light or city light.

The new assistance functions are also revolutionary, however[1]:

  • Warning of recognised roadworks by projecting an excavator symbol onto the road surface
  • Aiming a spotlight at pedestrians detected at the roadside as a warning
  • Traffic lights, stop signs or no-entry signs are pointed out by projecting a warning symbol onto the road surface
  • Assistance on narrow road lanes (roadworks) by projecting guidelines onto the road surface

The topographic light is another new function. This takes hills into account on the basis of navigation maps, especially crests and depressions: when cresting a hill, for example, the headlamp does not shine upwards but is pivoted down parallel to the road surface. In depressions the light beam is raised to maintain the desired range.

DIGITAL LIGHT welcomes and says farewell to the driver with a special light show.

[1] Owing to road traffic regulations, the availability and functions of these new assistance functions may be restricted on a market-specific basis.
 
Stable, light and safe

Intelligent bodyshell design and innovations in restraint systems confirm the leading role of the S-Class when it comes to passive safety. The new aluminium hybrid bodyshell with an aluminium content exceeding 50 percent meets numerous requirements: A high level of crash safety, up to 60 kg less weight and a highly rigid bodyshell ensure outstanding handling characteristics accompanied by excellent noise and vibration comfort.

The bodyshell of the new S-Class was designed with a particular focus on lightweight construction. The newly developed aluminium/steel hybrid bodyshell increases the aluminium content to more than 50 percent by weight. The high proportion of aluminium is achieved by using cast and extruded structural components. This form of lightweight design and construction requires highly complex joining techniques. It demonstrates the know-how of Mercedes-Benz in the luxury saloon segment, as well as the quality arising from close, barely perceptible body joints and the highly precise fit of the design surfaces.

The extensive package of lightweight construction measures includes rigid extruded aluminium sections for the side members in the front, rear and sides. Specially developed, highly integrated diecast aluminium components are used at important nodal points in the structure.

The extremely stable side wall structure comprises the pillars, the side roof frame and the side members. The material mix of aluminium and high-strength steel alloys helps to reconcile the conflicting aims of lightweight design and crash resistance. The inner shells are partly made up of several components, with particularly large areas for the nodal points between the pillars, roof frame and side members according to the potential loads.

One-piece aluminium side wall panels are a highly effective lightweight construction feature. Particular importance was given to achieving close joints and high-quality radiuses. The body panels of the roof, bonnet, wings, boot lid and doors are also of sheet aluminium.

Passenger cell: protected by ultra high-strength and press-hardened steel

The Mercedes-Benz safety cell is the centrepiece of the safety system. It has a structure of hot-formed high-strength steel cross-members in the areas of the firewall and rear end. At the sides this is complemented with extremely rigid side sills of extruded aluminium sections, which are larger than in the preceding model, with four internal chambers.

The floor structure likewise has ultra high-strength and press-hardened steel alloys combined to form a highly functional platform. The loads arising in all impact scenarios are conducted into the main floor. The robust centre tunnel and the lateral side members provide the basis for this. These assemblies are connected using further cross-members and diagonal struts. The design of this support structure makes the use of lighter floor panels possible. These make a major contribution to weight efficiency. The load resistance of the tunnel, which is especially important for frontal impacts, is achieved using connected sections of high-strength steel. The wall thicknesses vary according to expected loads.

Front: Protection of other road users

The front structure consists of an annular upper structure, the side members and the integral carrier. Additional polymer connecting elements between the crash levels ensure particularly effective energy absorption in the early phase of a crash. The integral carrier supports the engine, steering and lower suspension arms, and uses a special crash support system to direct longitudinal forces into the floor structure during a frontal collision. In the case of semi-overlapping collisions, the cross-connections in the front section are able to activate the side unaffected by the impact, e.g. the right side of the structure in case of a semi-overlapping collision on the left, and vice versa.

In cases of heavier deformation, the wheels are supported against the rigid side wall and the wheel impact element positioned ahead of it. The geometry and strength of the side sills are configured accordingly. Above the pedal floor panel the firewall is reinforced by an exterior cross-member of high-strength steel, which is supported by the A-pillars.

As well as occupant protection, compatibility with other road users was an important development objective. For this purpose, as an addition to the previous concept, the front flexural member is designed to provide an even more stable and broad impact surface for the other vehicle in an accident, for example.

Rear section: two zones with different purposes

The safety level of the rear structure is mainly achieved by a division into two crash zones. The zone housing the fuel tank components is kept almost deformation-free by cast aluminium sections. The purpose of the crumple zone behind this is mainly to dissipate impact energy with the help of extruded aluminium structures. In the case of a semi-overlapping collision, the rear flexural member directs the loads into the side unaffected by the impact, so that both side member paths can be activated.

Restraint systems: innovations for passengers in the rear

Especially in the S-Class, particular attention has always been paid to safety in the rear. In this respect, Mercedes-Benz has long devoted itself to extending the airbag and belt systems. Large windowbags cover the side windows like a curtain. These can be triggered according to the type of impact, e.g. a severe lateral collision or a rollover. The outer seat belts are equipped with belt tensioners and belt force limiters as standard, helping to reduce the loads acting on the occupants. Rear sidebags are optionally available, as is the beltbag: as an inflatable belt strap it distributes the loads acting on the upper body over a wider area.

The rear airbag is an innovation by Mercedes-Benz: this additional airbag can further improve the safely level of passengers in the rear during a severe frontal collision (see "Under the microscope"). However it still remains important for the occupants to wear seat belts. In the rear this is made more intuitive by the optional, illuminated designer belt buckles.
 
Frontal airbags for both rear occupants for the first time

Last year, in the Experimental Safety Vehicle ESF, Mercedes-Benz presented the ideas the company's safety specialists are working on. Among the more than 20 innovations were near-series developments such as the rear airbag, which now becomes available as optional equipment in the S-Class with long wheelbase. The frontal airbag for the rear seat deploys particularly gently thanks to its innovative construction using a tubular structure. During severe frontal collisions, the rear airbag can considerably reduce the loads acting on the heads and necks of occupants on the outer rear seats.

The rear airbag uses an innovative concept to inflate and position the air cushion. To this end, is has a special tubular structure which is rapidly inflated by compressed gas from a cold gas generator. The space between is filled with ambient air. Patented valves ensure that the air is retained when the occupant is immersed in the airbag, creating the protective effect. The tubular structure itself has a content of approx. 16 litres. The effective volume of the space in between is up to 70 litres. The airbag volume is configured so that a rear occupant wearing a seat belt can be protected before contacting the front seats.

Designing a rear airbag for a frontal collision requires a different concept from a conventional driver or front passenger airbag. This is because the spatial parameters are different, occupant behaviour varies widely and the airbag must be accommodated in the adjustable backrest of the front seat. In addition, children and adults sit very differently in the rear of a vehicle.

Particular attention was therefore given to gentle deployment of the airbag in case people or objects are in the deployment zone. The special design of this new airbag decisively contributes to compliance with the in-house requirements of Mercedes‑Benz, some of which were derived from tests on front passenger airbags. The inflating tubes give way when contacting obstructions, e.g. a child seat in the rearfacing position. The force is directed mainly past the obstacle as of a certain counterforce rather than against it.

The airbag enhances the restraining effect of the belt system, and can support the head and neck to decrease the loads on them significantly. In combination with a beltbag, the inflatable seat belt and the seat cushion airbag of the Executive seat, the S-Class sets new standards for rear seat occupant safety.
 
Additional side impact protection

New protective features for a severe lateral impact are introduced with the new S-Class. A suspension-based function has been added to the innovative PRE-SAFE® Impulse Side: when a side impact threatens, the vehicle body can be raised by the E-ACTIVE BODY CONTROL suspension (optional) within a few tenths of a second.

PRE-SAFE® Impulse Side, an innovation in the Experimental Safety Vehicle ESF 2009, had its world production premiere in 2015. The idea: to make use of the time before the impact, the system moves the occupant away from the door panel and towards the centre of the vehicle just before an impending side collision. To do this, the system inflates the air chambers in the side bolsters of the backrest within a fraction of a second when an imminent side impact is detected. This impulse not only moves the occupant away from the danger zone, increasing the distance from the door, as the impulse is also moderately transferred to the occupant. It mitigates the forces acting on him/her during a lateral impact. This can substantially lessen the load exerted on the ribcage by the side collision, and greatly reduce the risk of injury.

Mercedes-Benz has now added a new function of PRE-SAFE® Impulse Side to its measures in the pre-accident phase: when a side impact threatens, the vehicle body can be raised by the E-ACTIVE BODY CONTROL suspension (optional) within a few tenths of a second. Radar sensors are used to recognise a potential side crash. The actuator is the E-ACTIVE BODY CONTROL suspension, which can raise the body upwards by up to 80 millimetres. This reduces the loads on the door structures, as the door sill can absorb more of the energy thanks to its higher position. As a result, deformation of the passenger cell and the loads acting on the occupants can be reduced.

During a severe side impact, the new centre airbag positions itself between the driver and front passenger seat, reducing the risk of their heads making contact It is integrated into the driver's seatback in the middle of the vehicle.

The centre airbag is triggered when a severe side collision is recognised and certain conditions are met. The main factors for deployment are the direction of impact, impact side, and front passenger seat occupancy.
 
Intelligent interlinking of hardware and digital solutions for protection against crime

Under the name URBAN GUARD, Mercedes-Benz is introducing a new, comprehensive product and optional equipment category for all model series. It bundles together existing and future products for the protection of the vehicle against vandalism and crime. With URBAN GUARD – an intelligent interlinking of hardware and digital solutions – Mercedes-Benz satisfies the worldwide rise in customer demand for security and property protection.

In conjunction with Mercedes me, the two packages URBAN GUARD Vehicle Protection and URBAN GUARD Vehicle Protection Plus enable all-round monitoring of the parked vehicle. URBAN GUARD comprises an anti-theft alarm system, tow-away protection with visual and audible warning in case of a detected change in position, an alarm siren, interior monitoring (triggered by movement in the interior) and preinstallation for theft and parking collision detection. In the case of the latter, the vehicle sensors register when the parked and locked vehicle is bumped or towed – or when someone attempts to break into the vehicle. If the service is active, the driver immediately receives detailed information via the Mercedes me App. By means of a push notification, he/she finds out how severe the parking damage is and in which area of the vehicle it occurred, for example. As soon as the vehicle is restarted, this information also appears once in the central display.

URBAN GUARD Plus is also able to locate stolen vehicles. In case of theft, this also makes it possible to recover the vehicle even if the thief has deactivated the vehicle tracking function, for example. This takes place in cooperation with the police. Parking collision recognition in the new S-Class uses camera images from the Parking package with 360° camera to visualise the vehicle's surroundings, e.g. when a collision has occurred. When a collision is detected, each camera takes three images within a few seconds. These images can be viewed in the central display. The accident can therefore be reconstructed with time and place.

Further services are planned for the URBAN GUARD Plus package. These include emergency deactivation of the electronic keys, expected to be available from mid-2021. In the event of loss or theft of the vehicle keys, this enables the customer to deactivate them via the Mercedes me App to prevent any misuse. The keys can also be reactivated via the Mercedes me App.

Individual services from the URBAN GUARD Plus package can be booked subsequently via the Mercedes me Store, e.g. assistance after vehicle theft.

Vehicles with an URBAN GUARD package bear a special label. This warns potential thieves that the vehicle is specially protected.
 
More electrification, more efficiency

When the new S-Class is launched, six-cylinder in-line petrol and diesel engines in various output classes will be available, with a V8 engine with integrated starter generator (ISG) and a 48-volt onboard electrical system to follow shortly afterwards. A plug-in hybrid with an all-electric range of around 100 km will follow in 2021.


With the introduction of the integrated starter-generator (ISG) in the S-Class powered by the M 256 six-cylinder in-line engine in 2017, the 48 volt onboard electrical system celebrated its world premiere. The ISG is responsible for hybrid functions such as boost or energy recovery, while allowing fuel savings that were previously reserved for high-voltage hybrid technology. The systematically electrified six-cylinder in-line engine in the new Mercedes-Benz S 500 4MATIC (combined fuel consumption: 8.4-7.8 l/100 km, combined CO2 emissions: 192-179 g/km)[1] has an output of 320 kW/435 hp and 520 Nm of torque. EQ Boost provides a further 250 Nm of torque as well as 16 kW (22 hp) for a short period.


Intelligent, forced induction that includes an electric booster compressor, as well as the integrated starter alternator (ISG) provide outstanding power delivery without turbo lag. In addition, the engine starts extremely quickly and comfortably, making the start/stop function almost imperceptible to the driver.


In addition, systematic electrification dispenses with the need for a belt drive for ancillary components at the front of the engine, which reduces its overall length. The slim design as an in-line engine, together with the physical separation of intake/exhaust, creates space for a near-engine emission control system. The 48 V on-board electrical system serves not only high power consumers, such as the water pump and air-conditioning compressor, but also the integrated starter-generator (ISG), which also supplies energy to the battery by means of highly efficient energy recuperation.


Efficient, powerful and clean: the six-cylinder diesel


The engine line-up is rounded off by the six-cylinder diesel (OM 656). To meet current and emissions control requirements, the engine already familiar from the preceding S-Class since mid-2017 has been developed further. This is based on an integrated technological approach consisting of a stepped recess combustion process, dynamic multi-way exhaust gas recirculation and near-engine mounted exhaust aftertreatment. Thanks to the near-engine insulated configuration, the emission control system has little heat loss and ideal operating conditions. Other features of the flagship engine variant in the premium diesel family include two-stage turbocharging and CAMTRONIC variable valve control. Its design is characterised by the combination of an aluminium engine block and steel pistons, as well as the further improved NANOSLIDE® coating of the cylinder walls.


The exhaust aftertreatment has been extended. Its components include:

  • a combination of three exhaust gas recirculation (EGR) paths: This consists of the high pressure EGR path, the low-pressure EGR path and variable exhaust valve control (CAMTRONIC ) for the return flow of hot exhaust gases to the combustion chamber during warm-up under low engine loads, or when the exhaust temperature is low.
  • a close-coupled NOx storage catalytic converter for reducing the nitrogen oxides
  • a DPF (diesel particulate filter with special coating for also reducing the nitrogen oxides)
  • an SCR catalytic converter (Selective Catalytic Reduction with a metered injection of AdBlue®) and
  • an additional SCR catalytic converter in the vehicle's underbody.

Setting the standard in the luxury class for many decades

The Mercedes-Benz S-Class follows a long tradition that extends back to the beginnings of the Mercedes brand in the early 20th Century. With the experience gained from 135 years of automobile engineering, Mercedes-Benz produces vehicles that take care of their occupants' safety and offers a comprehensive luxury experience that leaves owners more time for the important things in life. Each model has decisively influenced the automotive engineering of its era. Well before the official designation S-Class, the models in the executive and luxury class were the mainstay of the Stuttgart-based company's portfolio and have always stood for luxury, comfort, safety and lifestyle. The continuous ancestry of the S-Class begins with the model 220 (W 187) of 1951.

The unrivalled tradition of the Mercedes-Benz S-Class has roots that extend back to the beginnings of the Mercedes brand in the early 20th century. One early and very telling example is the Mercedes-Simplex 60 HP presented in 1903. In subsequent years, the product ranges of the Mercedes and Benz brands always featured several models in the executive and luxury class. Although open touring cars were the most popular body type at this time, the more powerful models in particular were also offered as luxurious saloons.

All this changed in the mid-1920s. In a time of increasing motorisation and traffic densities which the development of the road network was unable to match, safe driving characteristics, a comfortable interior and the best possible protection from wind, rain and dust became increasingly important. Saloon cars and Pullman models gradually prevailed over the open touring models. Important executive and luxury class models during this period were the supercharged Mercedes six-cylinder 15/70/100 hp and 24/100/140 hp models which appeared at the end of 1924. In 1928, following the 1926 merger between the two previously independent companies founded by Carl Benz and Gottlieb Daimler to form Daimler-Benz AG, the model range was joined by the Model Nürburg 460 (W 08) as the first
Mercedes-Benz production car with an eight-cylinder engine. With continuous further developments it remained in the model range until 1939, with the Model 500 as the last variant. From 1926 the entry-level model to the Mercedes-Benz executive class was the six-cylinder 12/55 HP, which was developed further to culminate in the Mercedes-Benz Mannheim 370 (W 10) introduced in 1931. 1933 saw the introduction of the Mercedes-Benz 290 (W 18) as a completely new design which was replaced by the Model 320 (W 142) in 1937.

When the model range was expanded with the Model 170 S from the lineage of the E-Class, company chairman Wilhelm Haspel introduced the S as the new model designation in 1949. He declared that the letter S stood for "Super" or "Special". Since the launch of the 220 S in 1956, it has been in continuous use by Mercedes-Benz in the luxury segment. The designation "S-Class" was officially introduced with the 116 series in 1972.

From the W 187 to the "Ponton Mercedes" (1951 to 1959)

In the post-war period, the direct lineage of the S-Class began with the six-cylinder Model 220 (W 187), with which Mercedes-Benz reentered the upper-class segment in 1951. In 1954 this was followed by a completely new model with the same designation. The new Model 220, also known internally as the 220 a (W 180), was the first Mercedes-Benz six-cylinder model of monocoque construction.

Its modern, spacious "Ponton" body provided a previously unknown level of comfort. In 1956, with the introduction of the improved and more powerful Model 220 S, the letter S became a permanent fixture in the nomenclature of the Mercedes-Benz luxury class. 1958 saw the début of the 220 SE (W 128), a more powerful variant of the luxury class model by virtue of petrol injection.

From the "Tailfin" to the high-performance saloon (1959 to 1972)

The "Tailfin" models 220, 220 S and 220 SE (W 111) introduced in 1959 derived their nickname from the guide fins on the rear wings. This new generation of the luxury class was a special milestone in automotive history, as this was when the safety body with crumple zones and a rigid passenger cell conceived by Béla Barényi first entered series production. The top model in this series, the 300 SE (W 112) presented in 1961, featured an air suspension system and the automatic transmission newly developed by Mercedes-Benz as standard.

In 1963 the long-wheelbase version of this model founded a new tradition for the luxury class saloons of Mercedes-Benz: The 100-millimetre longer wheelbase gave passengers in the rear a significant increase in legroom and travelling comfort. In 1965 the saloons of the 108 and 109 series replaced the "Tailfin" models. These distinguished themselves with their elegant, timeless design and generously sized windows. As well as models with a conventional steel suspension – internally designated the 108 series – there were air-sprung variants (109 series) which were likewise available with a longer wheelbase. In 1968 the 300 SEL 6.3 was presented as a special highlight. The new top model in the series was equipped with the powerful V8 engine of the Mercedes-Benz 600 (W 100), and offered sports car-like performance together with outstanding comfort.

Automotive trendsetters: the 116 and 126 series (1972 to 1991)

The name given to the 116 series introduced in 1972 now expressed what had been the norm at Mercedes-Benz for decades: the luxury class saloons bearing the "S" in their model designations were now officially known as the S-Class. The new designation was accompanied by a wealth of innovations. The integral safety concept included e.g. the collision-protected fuel tank, a four-spoke safety steering wheel, anti-soiling side windows, large headlamps, conspicuous indicators and ribbed, dirt-repelling rear lights. In 1977, the diesel era began in the luxury class with the 300 SD, though initially only for the North American markets. At the same time, the luxury diesel was the first production car with a turbodiesel engine. From 1978 the S-Class was the world's first car to be available with the anti-lock braking system ABS, which ensures steerability even during emergency braking. A world sensation at the time, ABS is nowadays an automotive standard.

The technology transfer from the S-Class to the other Mercedes-Benz model series, and then to the models of other manufacturers until it became state of the art, was systematically continued in subsequent years. In the 126 series introduced in 1979, the airbag became a central element in automobile safety in 1981. Other attributes of this S-Class generation were the aerodynamically optimised shape and systematic weight reduction for lower pollutant emissions, partly thanks to new light-alloy V8 engines. The 126 series also made its mark in terms of design: It was the first Mercedes-Benz passenger car to dispense with traditional chrome bumpers in favour of deformable plastic bumpers that could withstand a minor parking collision without damage.

Luxury in its highest form: the 140 and 220 series (1991 to 2005)

In 1991 the 140-series S-Class was the new flagship model. Its developers concentrated on maximum comfort, for example through generous dimensions and double glazing for optimised acoustic insulation. The top 600 SE and 600 SEL models were the first Mercedes-Benz production cars to be powered by a V12 engine. The entry level in terms of power was marked by the 300 SD Turbodiesel, which now made the luxury class diesel available outside North America as well. This generation of the S-Class likewise introduced a trailblazing safety innovation in automobile engineering: ESP®, which became standard equipment in the V12 variants from 1995 and was optional equipment for the V8 models. Brake Assist BAS was added in the following year.

When the time for a model changeover came in 1998, the new 220-series S-Class was given a more understated design. The major development aims were to save weight while further improving safety and comfort. Despite dispensing with the weight-intensive double glazing, the new model generation offered even further improved comfort thanks to e.g. the new, electronically controlled AIRMATIC air suspension, the control and display system COMAND and the innovative intelligent cruise control system DISTRONIC. The active Active Body Control (ABC) suspension available from 1999 reduced body roll and achieved a previously unknown level of refinement. Customers with sporty ambitions were attracted to the S 55 AMG: an AMG model was officially shown in the S-Class price list for the first time. In autumn 2002, the S 600 as the regular top model without an AMG badge was treated to a power increase which enabled it to break the 368 kW (500 hp) barrier for the first time. At the same time a further trailblazing innovation had its debut on the 220 series: the preventive occupant protection system PRE-SAFE®. With the model facelift, Mercedes-Benz also offered the S-Class with the intelligent all-wheel drive system 4MATIC for the first time.

Trailblazing innovations: the 221 series (2005 to 2013)

The 221 model generation presented in 2005 combined an expressive exterior with a luxurious interior. The central controller of the further improved COMAND system allowed fast and intuitive control of the increasingly complex functions and menus. The pioneering technical innovations included active Night View Assist and further developments of the distance control system DISTRONIC PLUS and Brake Assist Plus, which were expanded to form PRE-SAFE® Brake with autonomous partial braking in 2006. Further assistance systems such as Blind Spot Assist, Lane Keeping Assist and Speed Limit Assist also relieved the driver's workload.

The updated generation of the 221 series appeared in 2009. The S 400 HYBRID was the first luxury-class vehicle with a hybrid drive system, and also the first standard-production passenger car with a lithium-ion battery. Introduced in 2010, the S 350 BlueTEC as a diesel variant and the S 350 and S 500 BlueEFFICIENCY with economical and powerful direct-injection petrol engines were models of efficiency. In early 2011 Mercedes-Benz introduced a highly-efficient four-cylinder engine into the S-Class for the first time with the S 250 CDI.

With networked safety systems: the 222 series (2013 to 2020)

The 222-series S-Class introduced in 2013 set new technical standards, e.g. as the first car in the world to dispense completely with light bulbs and feature only energy-saving LED technology both in the exterior and interior. Outstanding efficiency was ensured by modern powertrains, also using hybrid technology.

The S-Class became even more of a guiding star in automobile development with the Intelligent Drive system. It is under this name that Mercedes-Benz groups all of its networked safety and driving assistance systems. Intelligent Drive makes driving even safer and more comfortable than before. These also include assistance systems that relieve driver stress and can make semi-automated driving possible.

As early as August 2013, the S 500 INTELLIGENT DRIVE research vehicle covered the historic Bertha-Benz route from Mannheim to Pforzheim to show how the future of autonomous driving might look with such networked technologies: Its systems were able to master the highly complex requirements of an autonomous journey along country roads and in urban traffic.

The next development stage of Intelligent Drive took another major step towards autonomous driving in the facelifted variant of the 222 series, which was presented in summer 2017: For example, Active Distance Assist DISTRONIC and Active Steering Assist give the driver even more convenient support when keeping a safe distance and steering. Standard equipment for the 222-series S-Class from model year 2017 included Active Brake Assist, Crosswind Assist, ATTENTION ASSIST, Traffic Sign Assist, the occupant protection system PRE-SAFE® and the new PRE-SAFE® Sound.
 
Automotive luxury experienced in a completely new way

The S-Class stands for the fascination of Mercedes-Benz: legendary and traditional engineering expertise defines the luxury segment in the automobile industry. The new S-Class can be experienced with all the senses – seeing, feeling, hearing and smelling – while offering numerous innovations in the areas of driver assistance, protection and interaction. Mercedes-Benz is shaping the next generation of individual mobility for our times with innovations that place the focus on people. The new S-Class uses digitisation for a car that responds empathetically to the needs and wishes of its driver and passengers.


Modern luxury attains the next level in the interior of the S-Class. The designers have created a feel-good ambience with lounge character marked by elegance, high quality and lightness. The dashboard with its new architecture, modern surface design and ergonomic display arrangement is a particular highlight. But the feel-good aspect goes even deeper: With high ride quality and low noise levels as well as an extensive range of ENERGIZING Comfort programmes, the
S-Class looks after the well-being of its passengers. They also stay fit thanks to the effective air filtering system, which signals its newly gained capability with the new name ENERGIZING Air Control.


The new Mercedes-Benz S-Class has become more intelligent in many areas, and the driving experience is at the next level. Digital innovations such as in MBUX (Mercedes-Benz User Experience) are joined by innovations that increase driving enjoyment while making driving even safer: among them are rear-axle steering with a large steering angle and safety innovations such as the rear airbag. As a new function of PRE-SAFE® Impulse Side, the active E-ACTIVE BODY CONTROL suspension can raise the vehicle body (on both sides) just before an impending side impact. Following systematic further development, the driving assistance systems are a further step towards autonomous driving. Thanks to improved environmental sensors, for example, the parking systems give the driver even better support when manoeuvring at low speed. The integration into MBUX means that the level of visualisation has now entered a whole new dimension.


For over 100 years: the luxury class as the embodiment of the Mercedes-Benz brand


The S-Class is the centrepiece of the brand, and stands for the fascination of Mercedes-Benz: legendary engineering expertise and a heritage of craftsmanship meet progressive digital innovation. The S-Class combines artificial intelligence with the experience gained from 135 years of automobile engineering. Around 70 years ago, Mercedes-Benz laid the foundations for this model series with the model 220. Since its market launch in 1951, more than 4 million
S-Class Saloons have been delivered to customers around the world. The designation "S-Class" was officially introduced with the 116 series in 1972. In the last 10 years the S-Class Saloon has been particularly popular in China, the USA, South Korea and Germany. All in all, since the launch of the generation that is now in its runout phase, more than 500,000 S-Class Saloons have been sold.


The loyalty rate for this model series is especially high. For example, around 80% of customers in Western Europe who previously drove an S-Class once again opted for a Mercedes-Benz model. In the US, more than 70 percent do so. Around the world the S-Class Saloon is predominantly sold in the long wheelbase version: Around 9 out of 10 customers opt for the long version of the S-Class Saloon.

MBUX: a new dimension in personalisation and interaction

No other innovation in recent years has so radically changed the operation of a Mercedes-Benz as MBUX (Mercedes-Benz User Experience). The second generation of this learn-capable system now débuts in the new S-Class. The vehicle interior is even more digital and intelligent, as both the hardware and software have made great strides: brilliant displays on up to five large screens, in part with OLED technology, make the control of vehicle and comfort functions even easier. The possibilities for personalisation and intuitive operation have become far more extensive. This certainly applies in the rear, but also to the driver: For example, the new 3D driver display allows a spatial view at the touch of a button for the first time. A real three-dimensional effect is achieved without having to wear 3D glasses.

Two different head-up displays (HUDs) are available on request. The larger HUD provides augmented reality (AR) content. When navigating, for example, animated turn-off arrows ("fishbones") are virtually and precisely projected onto the road lane. For the assistance functions, information from e.g. Active Distance Assist is shown. The image appears virtually at a distance of 10 metres. the display area corresponds to a monitor with a 77-inch diagonal.

The voice assistant "Hey Mercedes" is even more learn- and dialogue-capable by activation of online services in the Mercedes me App. Moreover, certain actions can be performed even without the activation keyword "Hey Mercedes". These include accepting a telephone call. "Hey Mercedes" now also explains vehicle functions and answers general knowledge questions. In the S-Class the voice assistant can also be controlled from the rear.


Using cameras in the overhead control panel and learning algorithms, MBUX Interior Assist recognises and anticipates the wishes and intentions of the occupants. It does this by interpreting head direction, hand movements and body language, and responds with corresponding vehicle functions. As well as enhancing operating convenience, MBUX Interior Assist improves safety. Even before the journey begins, it notifies the driver if the camera has detected a child seat on the front passenger seat but seat belt is not fastened, for example.

With the MBUX Smart Home function, the S-Class now also becomes a control centre for the home, because the homes of many people are increasingly intelligent: mobile intelligence ensures maximum operating convenience from afar. WLAN and sensors make the home capable of communication: temperature and lighting, roller blinds and electrical appliances can be remotely monitored and controlled. Motion detectors and window contacts inform the user of welcome or unwelcome visitors.

Dimensional concept and interior design: generous ambience with a lounge-like nature

The S-Class has always been a place for comfortable travel and relaxed working. With the new generation, the interior has fully evolved into a "third place", a refuge between the home and workplace. Nearly all comfort-related dimensions of both variants, the S-Class with short and long wheelbase, have been improved in the front as well as on the rear seats. The sense of space is accordingly generous.

The desired harmony between digital and analogue luxury results in a revolutionary interior design, including associations with interior architecture and yacht design elements. The sculptured look of the dashboard, centre console and armrests appears to float above an expansive interior landscape. The systematic reduction in the number of controls underscores the minimalist appearance of the interior. A fine divide between the upper section of the dashboard and the large trim element structures the area and creates horizontal breadth.

Alongside up to five screens, the highlights include the large areas of trim in the dashboard and in the rear (in the Comfort Seat variant). These flow around the passengers and are a systematic further development of the wrap-around effect. One particularly attractive version of the trim is an open-pored wood veneer shot through with inlays of real aluminium that follow the contours. New design elements include the flat, four-square centre vents with horizontal nacelles. Two slim, vertical side vents on each side round off the ends of the dashboard.

The driver display and media display offer a comprehensive aesthetic experience The appearance of the screens can be individualised with a choice of four display styles (Discreet, Sporty, Exclusive, Classic) and three modes (Navigation, Assistance, Service)

Seats: Plenty of high-tech for outstanding long-distance comfort

The seats literally invite the occupants to sit down and relax. The flowing, three-dimensional layer design theme gives an impression of lightness. Different finishes give the seats different characters. For example, the flowing longitudinal piping of Lugano leather lends them a noble, avantgarde look, while the progressive diamond pattern of nappa leather and Exclusive nappa leather is more classical and expressive.

Up to 19 motors in the front seats make for comfortable seating – a number that indicates the complexity of the technology installed in the seats. Yet comfort is not enough: the seats also play a major part where safety is concerned. And of course when it comes to luxurious wellbeing: all the seats available for the S-Class carry the seal of approval by the Healthy Seating campaign[4].

Ten different massage programmes are available in the new S-Class. These use the vibration motors, and can enhance the effect of a relaxing massage with warmth on the hot-stone principle. To this end, the seat heating is combined with the inflatable air chambers in the active multicontour seats. The air chambers are now closer to the seat surface, and are therefore even easier to control and feel.

Five different rear seat variants make it possible to configure the rear of the S-Class as a working or rest area. One new feature is the heatable additional cushion for the head restraint, which is available for the two electrically adjustable rear seats. The adjustment range and angle of the front passenger seat in the chauffeur configuration and the reclining seat behind it have been improved as well.

The ENERGIZING Comfort programmes: Comfortable travel while staying fit

At the touch of a button or by voice command, the holistic "Fit & Healthy" approach of ENERGIZING Comfort provides a tangible experience of the different comfort systems in the S-Class, and features programmes that bundle them into worlds of experience. At the same time, the system creates a suitable atmosphere in the interior – for example, invigorating in case of monotonous stretches of road or relaxing in case of an elevated stress level. The ENERGIZING COACH even suggests an appropriate vitalisation or wellness programme based on vehicle and trip data. It also factors the information about sleep quality and stress level into its intelligent algorithm if the driver has a suitable wearable.

Mercedes-Benz has fundamentally improved ENERGIZING comfort control in the new S-Class. Innovations such as a massage based on vibrating motors in the seat cushion and resonance transmission by the Burmester® high-end
4D surround sound system are integrated. This makes bass tones feelable. Direct reproduction of the sound resonance in the seats adds another level to the three-dimensional listening experience – 4D sound inspired by the acoustic massage. The perceived intensity of the sound can be individually adjusted for each seat. The music becomes even more emotional thanks to this feelable component. Two exciters are integrated into the backrest of each seat for this purpose.

Automated driving and driving assistance systems: even more support for the driver

The home office will soon be mobile – including for people behind the wheel. At least if they drive a vehicle bearing the three-pointed star: for Mercedes-Benz wants to bring about the technical realisation and safe operation of an S-Class driving in conditionally automated mode and to meet the exacting legal requirements for what is known as a Level 3 system[5]. It is expected that from the second half of 2021 the S-Class will be able to drive in conditionally automated mode with the new DRIVE PILOT, in situations where traffic density is high or in tailbacks, on suitable motorway sections in Germany. By taking pressure off the driver, this allows them to undertake secondary activities[6] such as browsing on the internet or dealing with emails in the In-Car Office, and so win extra time.

In the new S-Class, Mercedes-Benz comes another big step closer to its vision of accident-free driving. The driver is supported by numerous new or extended driving assistance systems. He/she thereby has a reduced workload in day-to-day situations, and is able to drive comfortably and safely. When danger threatens, the assistance systems are able to respond to impending collisions as the situation demands. The operating principle of the systems is made visible by a new display concept in the driver display.

Thanks to improved environmental sensors, the parking systems give the driver even better support when manoeuvring at low speed. Operation is faster and more intuitive thanks to integration into MBUX. The optional rear-axle steering is integrated into the parking assistants, with the calculation of trajectories adapted accordingly. Emergency braking functions serve to protect other road users,too.

The driver can park and unpark the car via smartphone with remote parking assist. Operation has been simplified considerably. If specified with preinstallation for the INTELLIGENT PARK PILOT, the S-Class is prepared for Automated Valet Parking (AVP, SAE Level 4). In conjunction with the necessary optional equipment and the corresponding Connect service (depending on country), the new S-Class has the onboard technology to enter and leave multi-storey car parks equipped with an AVP infrastructure in highly automated mode and without a driver, provided that national legislation permits such operation.

Suspension systems: more manoeuvrable and dynamic with rear axle steering

Innovative suspension systems ensure an impressive travel experience in the new S-Class. Rear-axle steering (optional) with a steering angle of up to 10° improves manoeuvrability in urban areas to the level of a compact car. The turning circle is reduced by up to two metres.

The optional, fully active E-ACTIVE BODY CONTROL suspension on a 48 V basis offers a unique synthesis of comfort and agility, plus additional protection in the event of a lateral collision. The AIRMATIC air suspension with continuously adjustable damping ADS+ is standard equipment. Close networking between all the suspension and control systems ensures maximum stability and safety. Mercedes-Benz has now added a new function of PRE-SAFE® Impulse Side to its measures in the pre-accident phase: When a side impact threatens, the vehicle body can be raised by up to 80 millimetres by the E-ACTIVE BODY CONTROL suspension within a few tenths of a second. This reduces the loads on the door structures, as the door sill can absorb more of the energy thanks to its higher position. As a result, deformation of the passenger cell and the loads acting on the occupants can be reduced. Radar sensors are used to recognise a potential side crash.

Exterior design: perfect proportions for a classical appearance

With a short front overhang, a long wheelbase and a balanced rear overhang, the S-Class is designed as a classical saloon with perfect proportions. The wide track and flush-mounted wheels with modern designs give the vehicle a muscular look. The so-called character lines have been greatly reduced along the sides. Cleverly contoured surfaces with a sculptured look create special light effects. The front section impresses with its high-status radiator grille.

The headlamps characterise the front aspect of the car. They have the three-point daytime driving light signature that is typical of the S-Class, but this is flatter and somewhat smaller overall. The flush-mounted door handles (optional) are a completely new development. They are electrically extended when the driver approaches, or the outer surface of the door handle is stroked. Keyless access is provided by KEYLESS-GO.

The dynamic appearance of the car is continued at the rear. Thanks to precisely designed, highly detailed interior features and certain animated functions, the rear lights contribute to the impression of high quality. They make the new S-Class unmistakable in both their day and night design.

The lights: with innovative digital technology both inside and out

The optional DIGITAL LIGHT system enters series production for the first time at Mercedes-Benz. This makes completely new assistance functions possible[7]:

  • Warning of recognised roadworks by projecting an excavator symbol onto the road surface
  • Aiming a spotlight at pedestrians detected at the roadside as a warning
  • Traffic lights, stop signs or no-entry signs are pointed out by projecting a warning symbol onto the road surface
  • Assistance on narrow road lanes (roadworks) by projecting guidelines onto the road surface.

In each headlamp, DIGITAL LIGHT has a light module with three extremely powerful LEDs with light that is refracted and directed by 1.3 million micro-mirrors. The resolution is therefore more than 2.6 million pixels per vehicle. This allows highly precise light distribution. It makes Highbeam Assist over 100 times more precise then 84-pixel light when excluding oncoming traffic or road signs from the light beam. Light/shadow graduations and the light distribution of all the other adaptive light functions are also realised with considerably more precision, optimising illumination by e.g. fog light, motorway light or city light.

Thanks to LED technology, the new S-Class has also taken a leap forward in its interior lighting: Mercedes-Benz has now realised interactive interior lighting for the first time. The active ambient lighting (optional) is now integrated into the driving assistance systems, and is able to reinforce alerts visually. This also makes corresponding feedback possible for the comfort systems. This applies to the climate control system or the 'Hey Mercedes' voice assistant.

Aerodynamics: extensive airflow simulations in the early development phase

With a Cd figure from 0.22,[8] the S-Class is one of the world's most aerodynamic cars, and especially so in the luxury saloon segment . Although the frontal area (A) of the new S-Class has increased slightly to 2.5 sq. m., the drag coefficient has been reduced even further compared to the preceding model. The product of Cd and A is 0.56 sq. m., which is 200 sq. cm less than for the previous model after its last facelift. Aerodynamic measures affecting the body, underbody and detachable parts allow a good showing in the wind tunnel and in real operation. Extensive airflow simulations were already carried out using high-performance computer clusters during an early development phase.

The S-Class has also achieved further improvements in aeroacoustics. The previous generation already excelled with a very high level of interior noise comfort. The new model is even quieter. The high rigidity of the bodyshell provides the basis for outstanding noise and vibration comfort, and this is enhanced with fine-tuning. For example, the apertures for the cable grommets in the firewall have double seals. To achieve an engine sound that is perceived as refined and unobtrusive in the interior, the firewall insulation has been extended into the side areas of the A-pillars and the floor area. Mercedes-Benz is also using acoustic foam in certain bodyshell sections for the first time.

Powertrain: more electrification, more efficiency

Six-cylinder in-line petrol and diesel engines in various output classes are the first engine variants for the new S-Class.
A V8 engine with an integrated starter-generator (ISG) and 48-volt onboard electrical system will be available soon after. A plug-in hybrid with an all-electric range of around 100 kilometres will follow in 2021.

Vehicle body and accident protection: new frontal airbags for rear passengers


Intelligent bodyshell design and innovations in restraint systems confirm the leading role of the S-Class when it comes to passive safety. The new aluminium hybrid bodyshell with an aluminium content exceeding 50 percent meets numerous requirements: A high level of crash safety, lower weight and a highly rigid bodyshell ensure outstanding handling characteristics accompanied by excellent noise and vibration comfort.


In 2019, in the Experimental Safety Vehicle ESF 2019, Mercedes-Benz presented the ideas the company's safety specialists are working on. Among the more than 20 innovations were near-series developments such as the rear airbag, which now becomes available as optional equipment in the S-Class. The frontal airbag for the rear seat deploys particularly gently thanks to its innovative construction using a tubular structure. During severe frontal collisions, the rear airbag can considerably reduce the loads acting on the heads and necks of seat belt wearing occupants on the outer rear seats.


During a severe side impact, depending on the direction of impact, impact severity and front seat occupancy, the new centre airbag positions itself between the driver and front passenger seat, reducing the risk of their heads making contact. It is integrated into the driver's seatback in the middle of the vehicle.


Sustainability: environmentally compatible development


More than 98 kg of components made from resource-conserving materials are used in the S-Class. The number of components containing recyclates is now 120 – more than twice as many as in the preceding model. Another 40 kg or so are made from renewable raw materials. The process of environmentally compatible development with specific targets is firmly embedded in the overall development process. Environmental aspects are already taken into account in the conceptual phase.


A new, recycled thread is now used for the floor coverings. This thread - brandname Econyl® - consists of regenerated Nylon. It is manufactured by recovering Nylon waste destined for the landfill, for example old fish nets and fabric remnants from mills and carpets. These are collected and transformed into a new thread having the same properties as nylon from new raw materials. The recycling process used to produce the thread saves CO2 in comparison with new production. It also enables Mercedes-Benz to keep materials in circulation.


History: setting the standard for the luxury class for many decades


The Mercedes-Benz S-Class follows a long tradition that extends back to the beginnings of the Mercedes brand in the early 20th Century. Each model has decisively influenced the automotive engineering of its era. Well before the official designation S-Class, the models in the executive and luxury class were the mainstay of the Stuttgart-based company's portfolio and have always stood for luxury, comfort, safety and lifestyle. The continuous ancestry of the S-Class begins with the model 220 (W 187) of 1951. The designation "S-Class" was officially introduced with the 116 series in 1972.

A new dimension in personalisation and interaction

No other innovation in recent years has so radically changed the operation of a Mercedes-Benz as MBUX (Mercedes-Benz User Experience). The second generation of this learn-capable system now débuts in the new S-Class. The vehicle interior is even more digital and intelligent, as both the hardware and software have made great strides: brilliant displays on up to five large screens, in part with OLED technology, make the control of vehicle and comfort functions even easier. The possibilities for personalisation and intuitive operation have become far more extensive. This certainly applies in the rear, but also to the driver: For example, the new 3D driver display allows a spatial view at the touch of a button for the first time. A real three-dimensional effect is achieved without having to wear 3D glasses.


The voice assistant "Hey Mercedes" is available on every seat, and even more learn and dialogue capable by activation of online services in the Mercedes me App. Moreover, certain actions can be performed even without the activation keyword "Hey Mercedes". These include accepting a telephone call. "Hey Mercedes" now also explains vehicle functions, and can e.g. help when asked how to connect a smartphone by Bluetooth or where the first-aid kit can be found. Thanks to the Smart Home function, domestic equipment and household appliances can also be networked with the vehicle, and voice-controlled remotely (see separate chapter for details). "Hey Mercedes" is now also able to recognise vehicle occupants by their voices. Once the individual characteristics of the voice have been learned, this can be used to access personal data and functions by activating a profile.


Two different head-up displays (HUDs) are available on request. The larger HUD provides augmented reality (AR) content. When navigating, for example, animated turn-off arrows ("fishbones") are virtually and precisely projected onto the road lane. For the assistance functions, information from e.g. Active Distance Assist is shown. The image appears virtually at a distance of 10 metres. This long distance allows a very large image: the display area corresponds to a monitor with a 77-inch diagonal. (see Glossary for details).


However, the unique feature of MBUX is its networking with a wide range of vehicle systems and sensor data. MBUX Interior Assist is able to recognise numerous operating requests. It recognises eye-direction, hand gestures and the body language of the occupants, so as to assist with automatic vehicle functions as the situation requires (see separate chapter for details).


Up to five large screens with intuitive operation


The visual highlight in the interior is the large central display in portrait format. It is ergonomically well positioned, as the screen is within easy touch and vision between the driver and front passenger. The portrait format also allows longer lists to be displayed. The central display is available in two versions, the dimensions are shown in the table at the end of the chapter. The larger central display features OLED technology.


OLED stands for Organic Light Emitting Diode. Compared to LCD screens, the advantages of this technology are a better black level, even stronger contrasts and a lower energy consumption (see Glossary for details).


The user interface of the central display is divided into different areas. At the top is the entry area where the user can access the profiles by touch control. The content in the application band in the middle of the screen can be moved by horizontal and vertical swiping, depending on the chosen homescreen. Below this is the permanently displayed area for the climate controls.


On request the driver display is also available with a unique innovation: at the touch of a button, it is possible to switch to a 3D mode for a spatial view. A real three-dimensional effect is achieved with the help of eye-tracking, without having to wear 3D glasses. This optional version of the driver display has two integrated cameras. This stereo camera precisely determines the eye position of the user. Mercedes-Benz has developed appropriate distance adaptation methods for this, and the system has extremely low latency, i.e. there is almost no delay. The driver can therefore move freely. The image in the driver display is continuously adjusted. Cameras and face recognition are also used for a wide range of assistance and comfort functions. These include the new biometric authentication (see section on personalisation), drowsiness detection by ATTENTION ASSIST, settings for the exterior mirrors and (expectedly from the second half of 2021, initially in Germany) also monitoring of the head and eyelids during automated driving.


The appearance of the driver display and central display screens can be individualised with a choice of four display styles (Discreet, Sporty, Exclusive, Classic) and three modes (Navigation, Assistance, Service) For details see the chapter on interior design.


As a new element in the driver display, the ECO display (in the Classic style) takes the form of a ball rolling on a stylised road. The ECO display playfully helps the driver to adopt an efficient driving style.


Extensive range of infotainment functions for passengers in the rear


Take a quick look at the presentation on the way to the office, and discuss minor changes with your assistant by telephone conference? Or while away the long journey to your holiday home with the latest online films, while your brother next to you listens to his favourite audiobook? Whether managers or children – in an S-Class, and especially in the main markets of China and the USA, the boss often sits in the rear. Accordingly, Mercedes-Benz has systematically focussed on the rear for the new version of its flagship model. An example: passengers in the rear have the same extensive Infotainment and comfort features as the driver and front passenger, and can also watch films or surf the internet. They have access to up to three touchscreens and a variety of intuitive control options such as the voice control assistant "Hey Mercedes" - real multi-seat entertainment.


Screen content can be quickly and easily shared with other passengers Selection and amendment of navigation destinations is possible from the rear seats. MBUX high-end rear entertainment has two 11.6-inch displays with touch controls on the rear of the front seat backrests. The MBUX rear tablet is also optionally available. As a fully-fledged tablet, this can also be used outside the vehicle and (Android) apps can be installed. In the S-Class, the MBUX rear tablet is attached to a docking station located in the folding centre armrest or the business console, depending on the equipment level. This convenient remote control enables all the functions of the rear entertainment to be controlled from any seating position. As well as Mercedes-Benz Bluetooth headphones, a personal smartphone can be connected to the multi-seat entertainment by Wifi or HDMI.

Here are all five screens at a glance:

Music streaming: millions of songs to choose from


Mercedes-Benz has also integrated the music streaming service Spotify and Tuneln internet radio into the new S-Class. TIDAL and Amazon Music continue to be available as well. MBUX allows access to the usual songs and playlists as on a smartphone or other mobile device. Operation is intuitive, using the MBUX voice assistant "Hey Mercedes".


Personalisation is even more easy and convenient


A personal profile can be created directly in the S-Class and synchronised with the existing profile data of the Mercedes me account. By scanning a QR code with the Mercedes App, the vehicle is automatically connected to the Mercedes me account


Personal preferences such as a favourite radio station and preselected settings can be transferred to any seat via the personal Mercedes me profile. Up to seven different profiles with around 800 parameters are possible in the vehicle. The ambient lighting can be individually set by remote configuration, e.g. from home. As the profiles are now stored in the Cloud as part of Mercedes me, they can also be used in other Mercedes-Benz vehicles with the new MBUX generation.


Alongside the classic entry of a PIN, a new authentication method ensures a high level of security. Fingerprint, face and voice recognition are combined. This allows access to individual settings or verification of digital payment processes from the vehicle.


Always state of the art: over-the-air updates


More than 50 electronic components in the new S-Class can be updated with new software over-the-air (OTA), i.e. via a mobile data connection. These include the entire MBUX infotainment system, the driver display, the driving assistance systems and the MULTIBEAM LED and DIGITAL LIGHT lighting systems. This technology saves the customer time, as he/she does not need to visit a workshop for this purpose. Furthermore, the vehicle remains up to date throughout its lifecycle and is even equipped for new features that have not even been developed yet. The explicit consent of the user is always a precondition for OTA updates.


Since as early as 2016, Mercedes me connect has made it possible to update the communication module and the navigation map data over-the-air. In 2018, this was followed by the update capability for the MBUX infotainment system. In 2019 alone, Mercedes-Benz carried out almost 3.7 million free software updates around the world in this way. Since 2016 there have been 6.3 million OTA updates to navigation maps.
