The new Mercedes-Benz S-Class
The automotive benchmark in efficiency and comfort
Stuttgart/Shanghai. The new S-Class celebrates its world première with
extensive innovations at the Auto Shanghai. Among the highlights is an
all-new and highly efficient engine range with a series of new
technologies for electrification of the powertrain. Intelligent Drive takes
another step towards autonomous driving. And the undisputed leader in
the premium segment with regard to comfort and wellness sets new
standards in the interior. The market launch of the new S-Class starts in
the European markets in July.
Several new engines are planned for the new S-Class: in-line six
cylinders as diesel and petrol engines as well as a new V-8 biturbo petrol
engine. In addition, Mercedes-Benz plans a plug-in hybrid with an electric
range of about 50 kilometres. At the same time, ground-breaking
technologies such as the
48-volt Integrated Starter Alternator and the electric booster compressor
celebrate their world première.
The top-of-the-range model of Mercedes-Benz takes another big step
towards autonomous driving and elevates Intelligent Drive to the next
level. DISTRONIC Active Proximity Control and Active Steer Assist now
provide even more comfortable support for the driver to keep a safe
distance and steer. The speed is now adjusted automatically ahead of
curves or junctions.
MULTIBEAM LED headlamps and ULTRA RANGE High Beam turn night
into day. ROAD SURFACE SCAN, the forward-looking detection of
bumps, and the curve-tilting function CURVE are further unique features
of the S-Class in the segment of luxury saloons.

Page 2The ENERGIZING comfort control is a world-first entering series
production: This optional feature links various comfort systems in the
vehicle together, such as climate control, ambience lighting, massage and
fragrancing functions, and allows customers to configure a specific
wellness set-up to suit their mood or need. This enhances the physical
comfort and performance on the road.
"The development of the new S-Class was extremely extensive. With a
whole series of new features and functions the S-Class remains the
technological pioneer", says Ola Källenius, responsible on the Board of
Daimler AG for Group Research and Mercedes-Benz Cars Development.
The flagship from Mercedes-Benz was the best-selling luxury saloon in
the world in 2016. Since 2013, the company sold well over 300,000
saloons. Today there are six different S-Class body variants.
Three torches of light as an exclusive exterior design feature
Modern luxury in the new S-Class is manifest in maximum quality of
materials and workmanship. Status and technological competence are
now even more tangible. All models are fitted with a new radiator grille:
The versions with six and eight-cylinder engines sport three twin louvres
as well as vertical strips with a high-gloss black finish in the radiator grille.
The saloon with long wheelbase and V-12 engine is fitted with additional
chrome-finish vertical strips in the radiator grille.
The upgraded front with extensive chrome trim underscores the
exceptional status of the Mercedes-Maybach. Also new is the Maybach
logotype between the louvres of the radiator grille.
In conjunction with the new MULTIBEAM LED headlamps (optional
feature, details below), the S-Class features three distinctive torches of
light as an exclusive design element. The front bumper with pronounced
air intakes and sporty looks is also new.
The new LED lamps with crystal-look tail lamps stand out at the rear.
They look like jewels and ensure a characteristic design day and night. A
tail lamp light show that plays when the vehicle is unlocked and locked,
as well as three horizontal pairs of fibre optics are also new.
3. Daimler Communications,70546 Stuttgart, Germany
Mercedes-Benz– A Daimler Brand
Page 3All models are fitted with a redesigned lower bumper section with
integrated visible tailpipe trim. The tailpipes are framed by a chrome trim
element, which spans the entire width of the vehicle. Seven new light-
alloy wheels with diameters between 17 and 20 inches are available as
standard or options.
Control and display concept with wide-screen cockpit and new
generation of steering wheels
The interior of the new S-Class is characterised by the two new high-
resolution displays, each with a screen diagonal of 12.3 inches. Visually,
the two displays under one shared glass cover blend into a wide-screen
cockpit and as a central element consequently emphasise the horizontal
orientation of the interior design.
Like the instrument cluster, this wide-screen cockpit contains a large
display with virtual instruments in the direct field of vision of the driver as
well as a central display above the centre console. Because the cockpit is
fully digital, the driver can choose from three different display styles
("Classic", "Sporty" and "Progressive“) and also configure the information
and views relevant to them at will.
The new S-Class has touch-sensitive controls in the steering wheel. They
respond to swiping motions like the screen of a smartphone and enable
the driver to control the entire infotainment system without having to take
their hands off the steering wheel.
The infotainment system can also be operated via the touchpad with
controller in the centre console and by LINGUATRONIC voice control.
The operation of DISTRONIC and cruise control with control elements
directly on the steering wheel is another new feature.
Authentic materials and meticulous detail design
High-quality materials define the interior of the S-Class. These include, for
example, open-pore woods as well as leather-trimmed doors and upper
body edges, dependent on the trim level. Another Mercedes hallmark
clearly in evidence is the high-quality look and feel created through
meticulous attention to detail and craftsmanship.
4. Daimler Communications,70546 Stuttgart, Germany
Mercedes-Benz– A Daimler Brand
Page 4The material and colour concept has also been carefully composed, and
features a wide range of brown tones, including new colour combinations
such as magma grey/espresso brown or mahogany brown/silk beige.
Lighting atmosphere with 64 colours
As before, the interior lighting uses only long-lasting, energy-saving LED
technology. With 64 colours, the optionally extended ambience lighting
offers a wealth of individual settings. It adds lighting highlights, for
example, on the trim elements, the central display, the stowage facility at
the front of the centre console, the handle recesses, the door pockets, in
the front and rear footwells, on the overhead control panel, and on the
tweeters when the vehicle is equipped with the Burmester®
High-End 3D
Surround Sound System.
All S-Class models are fitted as standard with the KEYLESS start
function. This also marks the introduction of the new attractive generation
of keys, with a high-gloss black or high-gloss white design and different
ornamental frames.
World-first: wellness while driving
The ENERGIZING comfort control is a world-first entering series
production: This optional feature links various comfort systems in the
vehicle together. It systematically uses the functions of the climate control
system (including fragrancing) and the seats (heater, ventilation,
massage), the wall heating as well as lighting and musical atmospheres,
and enables a specific wellness set-up tailored to the mood and need of
the customer. This enhances the physical comfort and performance while
driving and during a break. ENERGIZING comfort can be experienced in
all seats, dependent on the equipment.
These six programmes can be selected:
Freshness
Warmth
Vitality
Joy
Comfort
5. Daimler Communications,70546 Stuttgart, Germany
Mercedes-Benz– A Daimler Brand
Page 5 Training (three trainings – muscle relaxation, muscle activation
and balance - each with several exercises)
The programmes all run for ten minutes. They are visualised on the head
unit with colour graphics, and backed by suitable music. Five songs are
already stored in the programme. The key function in the "Vitality“
programme, for example, is fast music with many beats per minute. The
S-Class repertoire therefore features "Feelin' Good" by Leon Riskin, for
instance. If personal music selections are available, e.g. via the Media
Interface, the system analyses them in the background and assigns them
to a programme based on the beats per minute (bpm). Individual
functions of the programmes can be deactivated.
ENERGIZING Comfort Control also incorporates the ambience lighting,
which is harmoniously tailored to each of the individual screen designs.
The light stages the interior like a work of art by composing colour worlds
from different colours.
The colour worlds can be temporarily replaced with special effects – for
example, a special lighting atmosphere welcomes the driver. In addition,
the climate control system indicates whether the temperature is adjusted
up or down through the colour of the ambience lighting. The brightness of
the LEDs adapts equally variably and can be set in five levels and four
zones: wide-screen cockpit, area of front seats, rear compartment, and
all. As a result, the ambience lighting harnesses the positive effects of
light on the well-being while on the road. This makes this equipment
feature a key part of ENERGIZING Comfort Control with its tailor-made
programmes.
In addition, the ambience lighting creates emotionally appealing contrasts
and structures the interior into levels. 64 colours, ten colour worlds and
three different lighting zones (footwells, trim element level and wide-
screen cockpit) enable an avant-garde lighting scene with spectacular
colour changes.
Powertrain: new engines with landmark technology
Mercedes-Benz S 560 4MATIC (fuel consumption combined: 8.5 l/100
km; CO2 emissions combined: 195 g/km) and Mercedes-Maybach S 560
4MATIC (fuel consumption combined: 9.3 l/100 km; CO2 emissions

Mercedes-Benz– A Daimler Brand
Page 6combined:
209 g/km): The new V-8 comes to the starting line with 345 kW (469 hp)
and 700 Nm. The new biturbo engine is among the most economical V-8
petrol engines in the world, and consumes about ten percent less fuel
than the predecessor. To lower the fuel consumption, four cylinders of the
new V-8 are deactivated simultaneously under partial load with the help of
the CAMTRONIC valve-lift adjustment system. This reduces gas-cycle
losses and enhances the overall efficiency of the four firing cylinders by
shifting the operating point towards higher loads. The turbochargers
positioned in the V of the cylinder banks represent another special
feature.
Mercedes-AMG S 63 4MATIC+ (fuel consumption combined: 8.9 l/100
km; CO2 emissions combined: 203 g/km): For superior performance with
significantly reduced fuel consumption, the AMG 4.0-litre V-8 Biturbo
engine with cylinder deactivation replaces the previous 5.5-litre V-8
Biturbo. Despite less displacement, the new engine produces 450 kW
(612 hp).
Most powerful diesel car in Mercedes-Benz history: In the Mercedes-
Benz S 350 d 4MATIC (fuel consumption combined: 5.5 l/100 km, CO2
emissions combined: 145 g/km) and S 400 d 4MATIC models (fuel
consumption combined: 5.6 l/100 km, CO2 emissions combined: 147
g/km), the new in-line six-cylinder diesel engine makes its début. It comes
in two output levels with 210 kW (286 hp) and 600 Nm as well as 250 kW
(340 hp) and 700 Nm. Even though it has noticeably more power than its
predecessor, the new engine consumes over seven percent less fuel. The
special traits of the top-of-the-line engine in the diesel family include the
stepped-bowl combustion process, two-stage turbocharging and for the
first time the use of CAMTRONIC variable valve-lift control. Its design
features a combination of aluminium engine block and steel pistons as
well as further improved NANOSLIDE®
coating of the cylinder walls.
The new six-cylinder diesel engine is designed to comply with future
emissions legislation (RDE – Real Driving Emissions). All the components
of relevance for efficient emissions reduction are installed directly on the
engine. The integrated technology approach combining the new stepped-
bowl combustion process, dynamic multi-way exhaust-gas recirculation
and near-engine exhaust-gas aftertreatment, for the first time combined
with variable valve-lift control, makes further reduced consumption with

configuration, exhaust-gas aftertreatment has low heat loss and
extremely favourable operating conditions.

Further hi-tech engines in the pipeline
In addition to the aforementioned engines, further new power units are
planned for the new S-Class: in-line six-cylinder petrol engines as well as
a plug-in hybrid with about 50 kilometres of electric range. At the same
time, ground-breaking technologies such as the 48-volt Integrated Starter
Alternator and the electric booster compressor celebrate their world
première.
New in-line six-cylinder petrol engine (M 256): The new in-line six-
cylinder petrol engine exemplifies the electrification process and
incorporates a 48-volt on-board power supply.
New intelligent forced induction that includes an electric booster
compressor, as well as an Integrated Starter Alternator provide
outstanding power delivery without turbo lag. The Integrated Starter
Alternator is responsible for hybrid functions, such as boost or energy
recovery, while allowing fuel savings that were previously reserved for
high-voltage hybrid technology. All things considered, the new R-6 engine
delivers the performance of an eight-cylinder with significantly lower
consumption.
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, together with the physical separation of intake/exhaust,
9. Daimler Communications,70546 Stuttgart, Germany
Mercedes-Benz– A Daimler Brand
Page 9creates space for near-engine exhaust aftertreatment. The 48-volt on-
board power supply serves not only high power consumers, such as the
water pump and air-conditioning compressor, but also the Integrated
Starter Alternator, which also supplies energy to the battery by means of
highly efficient energy recovery. The new in-line six-cylinder comes to the
starting line in two output levels.
Upgraded plug-in hybrid powertrain: Thanks to the significantly
increased battery capacity of 13.3 kWh, it is intended that the range for
all-electric driving will increase to about 50 km. In conjunction with the
new Mercedes-Benz Wallbox, the on-board 7.2-kW charger allows much
faster charging of the battery.
Intelligent Drive:the next step in driving assistance systems
The new S-Class takes another major step towards autonomous driving,
elevating Mercedes-Benz Intelligent Drive to the next level. DISTRONIC
Active Proximity Control and Active Steer Assist now provide even more
comfortable support for the driver to keep a safe distance and steer. The
speed is now adjusted automatically ahead of curves or junctions. This is
complemented by a considerably improved Active Lane Change Assist
and additional functions of the Active Emergency Stop Assist.
Thanks to enhanced camera and radar systems, the new S-Class has an
even better view of the surrounding traffic: In addition, for the first time it
makes use of map and navigation data to calculate driving behaviour.
This means that DISTRONIC Active Proximity Assist is able to assist
the driver in many situations based on the route, and conveniently adjust
the vehicle speed.
The "Assistance Graphics" menu of the instrument panel shows the driver
at one glance which assistance functions he selected and to what
situations the systems are currently responding. Unmistakable icons
provide him with information on the screen as well in the head-up display.
All functions are now controlled from the steering wheel. The new Driving
Assistance package includes but is not limited to the following functions:
10. Daimler Communications,70546 Stuttgart, Germany
Mercedes-Benz– A Daimler Brand
Page 10 DISTRONIC Active Proximity Assist uses substantially more
map and navigation data, can support the driver based on the
route, and conveniently adjusts the vehicle speed.
Active Steer Assist has been noticeably improved across its
entire performance range, resulting in markedly enhanced
customer benefits.
Active Lane Change Assist was considerably upgraded. Now
tapping the indicator stalk is all it takes to initiate a lane change.
This lane change is executed within the next ten seconds and
indicated in the instrument cluster with the appropriate visual
display, if the vehicle sensor system does not detect any vehicles
in the relevant safety zone the driver might have missed.
Active Emergency Stop Assist brakes the vehicle to a stop
when Active Steer Assist is engaged and the system recognises
that the driver is not intervening in the driving process on a
sustained basis.
Following vehicles in a tailback: In stop & go traffic on
motorways and similar roads, stops of up to 30 seconds are now
possible, during which time the S-Class starts moving again
automatically and follows the traffic ahead (in conjunction Active
Parking Assist).
Traffic Sign Assist: Posted speed limits and any potential no-
overtaking signs are displayed for the current section of the route
through image recognition and information from the digital road
map of the navigation system. The vehicle speed is compared
with the speed limit. When the driver selects the appropriate
settings, a visual/visual-audible warning signal is issued any time
the speed limit is exceeded. No-entry restrictions are also
recognised. Furthermore, the system warns of detected persons in
the area of pedestrian crossings.
Depending on the respective applicable national road traffic regulations,
Remote Parking Assist enables the driver to manoeuvre the vehicle into
tight parking spaces or garages by smartphone, so as to facilitate getting
in and out. The vehicle can be manoeuvred into parallel and end-on
parking spaces in both forward and reverse direction. Manoeuvring out of
end-on parking spaces is also possible, e.g. if the driver returns to their
vehicle to find that it has been blocked in. In Explore mode, the vehicle
can be manoeuvred forward and back for up to 15 metres and can avoid
detected obstacles with small steering corrections in the process.

Page 11Ride quality: MAGIC BODY CONTROL improved and now with
CURVE function
The S-Class made a technological statement of superiority in 2013 with
ROAD SURFACE SCAN. The system detects bumps ahead of the
vehicle and adjusts the ACTIVE BODY CONTROL suspension
accordingly. In the new S-Class this suspension control is further
improved: The stereo camera of the system now scans the road even
more thoroughly, even in dusk and at speeds up to
180 km/h. Another comfort enhancement is the CURVE curve-tilting
function, available in the S-Class Saloon for the first time. The body tilts to
the inside of the turn by up to 2.65 degrees and thereby reduces the
centrifugal forces perceived by the passengers.
Long-distance vision: MULTIBEAM LED headlamps with ULTRA
RANGE main beams
In 2013, the S-Class became the first automobile to use exclusively LEDs
as light sources. The Intelligent Light System is now optionally available
with MULTIBEAM LED headlamps and ULTRA RANGE main beams. The
ULTRA RANGE main beams produce the maximum light intensity
permitted by law, which results in the brightness of the main beams
remaining above the reference value of 1 lux over a distance of more than
650 metres. For the driver, this means a clear improvement of the already
very good lighting performance of current MULTIBEAM LED systems.
Adaptive High-Beam Assist Plus is part of the Intelligent Light System. It
allows drivers to drive with activated main beams permanently without
dazzling other road users. When there are oncoming vehicles or vehicles
in front, the LEDs of the MULTIBEAM LED main-beam modules are
partially switched off, masking out a u-shaped area of the light beam. The
other areas of the road continue to be illuminated with the high beam
(partial high beam).
Wireless charging of smartphones and new Concierge Service
The new infotainment generation also expands the telephony options:
With the help of near-field communication, the smartphone transforms
into the digital vehicle key and the controller for parking (see above).
12. Daimler Communications,70546 Stuttgart, Germany
Mercedes-Benz– A Daimler Brand
Page 12Mobile phones can be charged as standard wirelessly and without a
telephone holder. In addition, Multifunction Telephony (optional feature)
allows connecting mobile phones with the vehicle's exterior aerial.
Wireless charging works with all mobile devices that support or can be
retrofitted to support the Qi standard. The charging pad is integrated into
the stowage compartment at the front of the centre console. Wireless
charging is optionally also available in the centre console in the rear.
The "Business Telephony in the Rear" equipment feature was expanded
with additional functions such as connecting a second mobile phone and
transferring calls between front and rear passengers. The Bluetooth
handset was also redesigned.
Front and rear passengers now have more text messaging options. They
can now receive, send, forward and use voice-to-text to dictate text
messages. Telephone numbers from text messages and embedded
URLs can be used for further actions. The messages are also displayed
as pop-ups on the right half of the wide-screen cockpit. Another new
feature is the notification by text message if the vehicle is involved in a
parking dent. The sensors of the vehicle detect such a situation and
trigger a text message being sent to a preset mobile number.
The Burmester®
High-End 3D Surround Sound system with a system
output of 1520 watts was expanded with a speaker in the overhead
control panel and two speakers in the sides.
The new Concierge Service puts a host of individual services at the
disposal of Mercedes me connect customers: from making restaurant
reservations and obtaining tips about tourist routes, to gathering
information on cultural or sporting events and sending navigation
destinations directly to the vehicle. Registered users can establish a
telephone connection to the Concierge Service in the preset language in
20 countries throughout Europe by pressing the 'Info' button on the
overhead control panel or via the Mercedes me App. The personal
concierge takes care of everything else.
