F
irst Class in every situation

Stuttgart.
In the SUV world, the new GL
-
C
lass is setting new
standards in comfort, dynamics, safety, elegance

and

efficiency and
with this spectrum it is regarded as the S
-
Class among off
-
road
vehicles.

This premium SUV is ab
le to demonstrate i
ts exceptional
capabilities in everyday
situations

with dense city traffic,
over
very
winding roads or on well
-
buil
t

motorway
s as well as way off the beaten
track
.
Here the multi
-
talent's qualities are even more evident. Whether
driving
over tracks with potholes, continually altering road surfaces or
dusty natural trails interspersed with off
-
road sections


the superior
comfort of the seven
-
seater's ride as well as its outstanding power and
confident performance
are really convincing

eve
n
when

the going gets
really tough.

Relaxed


and that
mean
s

safe



driving

both on
-
road and off
-
road


is one
of the great strengths of the new GL
-
Class. Especially its NVH qualities
(noise, vibration, harshness) are very convincing and are on a par with
those of the S
-
Class. The high standards of comfort are derived from the
combined result of a very rigid bodyshell, a perfected drivetrain, improved
chassis and superb aeroacoustic finishing as well as the intelligent use of
new
-
style insulation materials.

At the same time, the GL
-
Class retains its
traditional advantages of being extremely responsive with outstanding off
-
road expertise.

Included in the standard package are the fully load
-
bearing air suspension
system AIRMATIC with its adaptive
shock
-
absorb
ing

system (ADS) as well
as a load recognition feature. In comparison with the previous model, the
AIRMATIC ADS provides outstanding comfort with greatly improved
handling, roadholding and driving dynamics. For example, both the standard
C
rosswind
A
ssist a
nd load recognition feature are able to compensate for
very varying driving conditions.
The optional active tilting stabiliser ACTIVE
CURVE SYSTEM uses its active lateral stabilisers for the front and rear
axles to
reduce

the roll angle when driving round
bends, thus providing a
greatly improved response and more fun behind the wheel. At the same
time, the system makes for better handling. An improved ride and increased
scope when driving off
-
road by actively decoupling the stabilisers are
among the other a
dvantages of the ACTIVE CURVE SYSTEM.

The GL is really well
-
equipped for going on tours off the beaten track. The
standard package also includes the permanent four
-
wheel drive 4MATIC, a
driving
-
off assistant, the

Downhill Speed Regulation DSR and a special
program for off
-
road driving. The ON&OFFROAD package of the new GL
-
Class with its six driving programs has greatly improved the vehicle

dynamics and driving safety
so that
the most suitable drive control for
ext
remely varying driving conditions both on the road and going cross
-
country

is always available
. From the "hardware" point of view, the
ON&OFFROAD package comprises an underrun protection for the engine,
fibre
-
reinforced underfloor panelling, a two
-
stage po
wer transmission with
reduction gears, a longitudinal differential lock and extended AIRMATIC
functions allowing a maximum ground clearance of 306 mm and fording
depth of 600 mm.

: Up to 20 per cent reduction in fuel
consumption

Both the BlueTEC

engine for the

GL 350 BlueTEC 4MATIC
and the

GL

500 4
MATIC BlueEFFICIENCY
with supercharged direct injection

BlueDIRECT

petrol engine give extremely efficient and outstanding
performances
.

The
fuel consumption of the

GL

350 BlueTEC 4MATIC
is

7.4 litres diesel per hundred kilometres which is about
20

per cent

less
than
its predecessor,
a
nd
at the same time it undercuts the future EU 6
emission standards
. The fuel consumption of the
320 kW

(435 hp) strong
petrol engine
GL 500 4MATIC BlueEFFICIENCY

has been

reduced by
18
per cent
.

With the change of models
the G
L range is being enriched by
an AMG version
for the very first time
.
In the high
-
performance SUV GL
63 AMG, the AMG 5.5 litre V8 Biturbo

engine provides a top

performance
of
410 kW

(557
hp
)
a
nd maxim
um torque of
760 N
m
. The GL 63 AMG
accelerates from zero
to 100 km/h in 4.9 seconds; it

has a

top speed
of
250 km/h (
limited electronically
). The NEFZ fuel consumption is 12.3

In addition to
the state
-
of
-
the
-
art engine technology, an extensive
BlueEFFIC
IENCY package
supports the outstandingly economic fuel
consumption
.
This includes the new seven
-
gear automatic transmission

7G
-
TRONIC PLUS

as well as the

standard ECO stop
-
start
function
.
The
intelligent generator management, electric power steering and r
educed

rolling resistance of the tyres also have a
fuel
-
saving effect
.

In comparison with its predecessor
(GL

350 BlueTEC 4MATIC)
, t
he
weight

of the
new GL
-
Class

has been reduced by 90 kg due to the extensive use
of
lightweight

construction methods
.
Thes
e include the use of light but
durable aluminium alloys
for the bonnet and wings. The front and rear
suspension links are also made of light alloys
. This pays twice over: On
the one hand the lower weight reduces energy requirements
, and on the
other hand
the vehicle provides a more comfortable ride due to its lower
unsprung mass
. Other
weight reductions

are the
new acoustic

windscreen, the magnesium cross beam of the
dashboard
,
the

BlueTEC

s
ystem
with

SCR

technology or

components such as the new electric
p
ower steering, the electric parking brake or a plastic engine support
.

The interior of the GL: First Class f
or seven people

In addition to its extremely comfortable ride with excellent dynamic driving
features both on the road as well as over very rough
terrain, the GL
-
Class
spoils its passengers with an interior which comes up to the first class
standards of

a luxurious saloon. Up to seven passengers are able to enjoy the
outstanding seating. The elegant interior decoration is dynamic and full of
vigour

with high
-
quality materials and great attention has been paid to
details;

the generous space arrangement has a perfect ergonomic design


the interior of the GL
-
Class conveys the feeling of well
-
being typical for
the Mercedes
-
Benz brand. Extensive trim el
ements in various kinds of
wood or in aluminium, controls in silver
-
chrome and upholstery in
permeable ARTICO man
-
made leather material with decorative
topstitching on the

seams in a contrasting colour underline the overall
high
-
quality impression.

As a

As another first for a series model SUV, Mercedes
-
Benz is offering an
opti
onal sound system for the GL
-
Class from the well
-
known manufacturers
of music systems Bang & Olufsen. The
Bang & Olufsen BeoSound AMG
High
-
End Surround
-
Sound System

with a total output of 1200 W and 14
high
-
end loudspeakers transforms the interior of the c
ar into a concert hall
with breathtaking
acoustic
.

Mercedes
-
Benz
is the first car manufacturer to
evaluate and
assess the
role of aeroacoustic which provides the decisive parameters for a
comfortable ride especially when travelling at higher speeds. As a
result,
the psychoacoustic characteristics of SUV models like the GL
-
Class

have
been considerably improved
. Here not only the high frequency wind
noises were rated, but also the low frequencies


especially those
concerning the comprehensibility and audibi
lity of spoken language.
A

comparison with the S
-
Class

proves j
ust how successful the GL
engineers were: the objective and subjective impression of noise lies at
the same level for both vehicles.
B
ecause of its
typical SUV design,
h
owever, it took a great
deal more effort to achieve these top results with
the GL
than with a luxury saloon
. Furthermore, the full
-
size SUV provides
excellent acoustic for seven passengers sitting in three rows


and that
under even the most unfavourable conditions as the off
-
roa
d
er

can be
used in a much wider variety of situations

than the saloon

including
travelling in remote areas far away from sealed roads.

and innovative impression. The difference lies in
a light wave conductor
for the position lights, LED

tech
n
ology indicators and the practical Night
View Assist PLUS which is available as an option. The daytime running
lamps, also in LED

technology are integrated in a chrome clasp in the
bumper and underne
ath the radiator grille the large underbody panel in
chrome look rounds off the self
-
confident appearance of the front.

The
well
-
balanced proportions of the side view (length 5120

mm, height
1850

mm) and the long wheelbase (3075

mm) underline the vehicle's

on
-
road emphasis, but at the same time the short body overhang at front and
rear together with the vehicle's great ground clearance point to its
suitability for off
-
road travel.
The rear with its two
-
piece LED rear lamps
using light wave conductor technol
ogy, a large roof spoiler, the bumper
with its modern "wing design" and the large chromed area of the
underbody panel complete its appearance as befits the social status of
this luxurious full
-
size SUV. For the first time there is an extensive AMG
exterior

sport package available for those GL customers who find it
increasingly important for their vehicle to have a sporting and dynamic
appearance.

Passive safety: All
-
round protection for all passengers

Maximum protection potential is provided by the passiv
e protection systems
for passengers in conjunction with the "electronic crumple zone" provided by
the assistant systems and the intelligent body construction
. Adaptable two
-
stage airbags for the driver and
front passenger
, knee bags for the driver,
sidebag
s

for the driver and
front passenger

(combined thorax/pelvis bags)
and window bags for all three rows of seats are part of the standard
package. The integration of the optional thorax bags in the backrest of the
tilt
-
adjustable folding seat in the middle r
ow of seats allows the airbag to
be in the best possible position regardless of the position of the backrest
.

Furthermore, there are 3
-
point seat belts for all seven passenger seats on
board. Also part of the standard package are the pyrotechnical inertia
reel
tensioners and constant belt force
-
limiters as well as electrically reversible
belt reel
-
in tensioners at the front, inertia reel tensioners and single stage
force
-
limiters on the outer seats of the middle bench seat as well as on
the rear single seat

The GL

possible
protection with regard to weaker road users such as pedestrians and
cyclists
. Among other things, the standard active bonnet comes into action

r seven passengers.

As a standard feature, the luggage compartment can be enlarged by
folding down the third row of seats electrically


either from the two rear
doors or from the luggage compartment


and putting them up when
required just by pressing a
button. Another innovation is the EASY
-
ENTRY system on both sides for the second row of seats


also with
optional electric controls


to give better access to the third row of seats
.
The middle row of seats has a great variety of adjustments, making the u
se
of interior space much more variable as for instance with a "cargo

to enlarge the size the luggage compartment
. It then provides a volume of
680 to 2300 litres which is greater than the high capacity provided by its
predecessor.

In comparison

with its predecessor, the passengers have a great deal
more elbow and headroom at their disposal in all three rows of seats. For
all the other classic standards for a comfortable ride such as the distance
between the rows or the width allowed for shoulder

already was the best in its class.

particular in the third row of seats the available space is also outstanding.
The easy access is also very impressive. Pa
ssengers can get into the
interior easily due to the wide opening angle of the doors at front and rear
and the high edge of the roof which is typical for SUV vehicles. Loading
the luggage compartment is also simple due to the height of 1.95 m under
the ope
n tailgate.

Benz vehicles, basic seat adjustments for legroom
and backrest angle can be made using the buttons in the

interior door

adjustments can now be made easily and clearly using the COMAND
controller on the centre console. After selecting the appropriate menu
using the button on the centre console, the graphic on the COMAND
display shows a mu

for the user: Infotainment, navigation and communication can all be used
easily and very simply with the COMAN

covered in nappa leather is standard and fitted with gear shift paddles and
12 buttons with various functions.

Below the central armrest with its integrated

ang & Olufsen BeoSound AMG High

End
Sound System

As another first for a series model SUV, Mercedes
-
Benz is offering an
optional sound system for the GL
-
Class from the well
-
known Danish
manufacturers of high
-
fidelity systems Bang & Olufsen. The
Bang & Olufs
en
BeoSound AMG High
-
End
Sound System

with 14 high
-
end loudspeakers, a
total output of 1200 W and
B&O ICE

power Class D Technology enhances
the listening pleasure in comparison with other known sound systems and

transforms the interior of the car into a co
ncert hall with breathtaking
acoustic.
The equipment allows the user to select either the high
-
end
studio sound "Reference" or wide
-
reaching spatial surround sound.
Furthermore, the sound fields can be directed exactly toward the driver's
and
front passeng
er
's seats or centrally. All the functions are easy to
operate using a special Bang & Olufsen menu in the COMAND
infotainment system.

As the driver and
front passenger

in a car practically never find
themselves

in the ideal position between the speakers,

the distance between each of

the loudspeakers and the passenger's ear is inevitably different and also
this involves a different time lapse. This means, for instance, that in a left
-
hand drive vehicle the sound waves take longer to travel from the right
h
igh
-
frequency tweeter to the right ear of the driver as from the left high
-
frequency tweeter to the left ear. This delay due to physical reasons is
compensated by

the digital sound processor (DSP)


and even individually for each of the
fourteen loudspeak
ers. Special software has been developed to provide
very precise sound tuning and this is stored in the DSP for every
individual seat. This means that passengers are able to select the
required seats in the Bang

&

Olufsen sound menu. The virtual sound
stag
e is perceived as being directly in front of the passengers and thus
corresponds to the natural human listening habits when enjoying music.
Every type of instrument


guitar, strings, wind section, piano or
synthesisers


is convincingly natural, fresh and

dynamic. The same is
true for the various types of voice: Singing from both men and women
sounds just as authentic as pure voice reproduction, for instance in news
programmes. It also does not matter what the personal musical tastes

of the passengers are

or what the source is: The Bang & Olufsen
BeoSound AMG High
-
End
Sound System

reproduces every type of music
perfectly from classical music to blues, jazz, pop, rock and electro to hip
-
hop, irrespective of whether it is from a CD, DVD, TV/Video, mp3 player

or the radio.

The Bang & Olufsen ICE Power® amplifier (ICE =
I
ntelligent,
C
ompact,
E
fficient) serves as the perfect addition to the 14 loudspeakers and the
DSP. The amplifier converts about 93 per cent of the input energy into
performance and is closely l
inked to the DSP.

A very important contribution to the outstanding listening pleasure is due
to the dynamic compensation for driving noises during very varying traffic
and environmental situations: The microphone integrated in the overhead
control panel
constantly supplies data on the current noise levels within
the car and their influence depending on the frequency. The digital sound
processor analyses all the wavebands and raises the volume as required
individually for each loudspeaker and for the varyi
ng frequencies. In this
way, very varying sources of noise can be compensated. One extreme
example: If the GL has to stop at traffic lights right next to road works
using an asphalt cutter, the DSP modulates the system so that the noise
input is compensate
d for as far as the limits of physical laws allow.

Compensation is also made for "normal" noises such as those from tyres,
wind, engine, gears or even rain.

Calm despite the storm: The new GL is
the quietest vehicle in the

whole of the SUV world

As the very first car manufacturer, Mercedes
-
Benz has researched the
psychoacoustic qualities of vehicles to find out more about aeroacoustic.

Here both high frequencies of wind noise as well as the contr
ibution of
low frequencies, and in particular the audibility of voices was examined
and optimised. During their research, the engineers devoted themselves
intensively to the airflow around the vehicle body, the sealing systems on
windows and doors as well
as the body
-
in
-
white. The main focus of such
work is not just on the absolute sonic pressure (dB (A)). The aim is rather
to generate acoustic which
is

as homogenous and harmonious as
possible, where neither definite frequency ranges nor individual vehicle
components or sectors are dominant, as from a speed of about 120 km/h
the wind noises are the dominant acoustic quantity. Tyre or engine noises
are relegated to the background.

I
ndividual aeroacoustic measures taken
:



optimised A
-
pillar and housing of outs
ide mirror



reinforcement of the underbody to avoid low
-
frequency noises



acoustic front windscreen and optional acoustic side windows made with
multilayer glass technology to provide great noise insulation



use of improved sealing systems with optimised lip
seals



additional aeroacoustic sealing levels in rear compartment



improved clamping for door windows


Just how successful the aeroacoustic engineers were in tuning the GL
"resonance box" can be seen by a comparison with the S
-
Class: The
objective and sub
jective impression of noise lies at the same pleasant
level for both vehicles. However, achieving these top results with the GL
requires a great deal more effort than with the luxury saloon. On the one
hand because of its typical SUV shape and the large fr
ont surface

On the other hand, the full
-
size SUV provides excellent acoustic for seven
passengers sitting in three rows even
under

unfavourable conditions as
the

off
-
road vehicle can be used in a much wider variety of situations than a

saloon


also
incl
uding travelling in remote areas far away from sealed
roads.

Clear proof of the importance of aeroacoustic for Mercedes
-
Benz is
shown by the development of new testing plants. Normal wind tunnels
have reached their physical limits as far as the further
optimisation of
aeroacoustic is concerned as here the interference from the testing
equipment is superimposed on the test results. To put it briefly: Mercedes
-
Benz vehicles like the GL
-
Class now run so quietly that innovative
developments using the present

testing equipment would require a great
deal of effort to achieve. That is why at the moment a revolutionary
interference
-
optimised wind tunnel is being built at the Mercedes
-
Benz
Technology Centre (MTC) in Sindelfingen. The testing installation will be
o
pened in 2013 and is a guarantee for future automotive development
that the company will continue to retain its lead in aeroacoustic over its
competitors.

Relaxed, comfortable and superior driving including a great deal

these are the great strengths of the GL

even better response and dynamic road handling. The nimble way this
full

heel drive goes about its business is
otherwise only to be found in much more compact and sporty off
-
roaders.
The fact that the quality of the riding comfort could be increased to such
an outstanding level despite

all the GLs dynamic handling is one of th
e special achievements of the
development team.
Especially the NVH qualities (noise, vibration,
harshness) of all the GL models are very convincing and are on a par with
those of the S
-
Class.

The high standards of comfort are derived from the
combined resu
lt of a very rigid bodyshell, a perfected drivetrain, improved
chassis and superb aeroacoustic finishing as well as the intelligent use of
new
-
style insulation materials.

compensates various loads and driving conditions and at the same time
acts as a level control. When driving way off the beaten track, the air
suspension increases off
-
road mobility with extra

riding height. The lifting or
lowering of the body can be activated at any time when the engine is
running and can either be done automatically or as the driver requires using
the control buttons on the centre console. The system is speed
-
dependent
and lo
wers the body at high speeds to minimise aerodynamic resistance
while at the same time increasing driving stability.

The main features of the
air suspension are:



A
ir
-
spring legs on the front axle with integrated ADS shock
-
absorbing
function



A
ir spring with

separate ADS shock absorber on the rear axle



S
upercharger with central pressure tank and electric pressure sensor



A
ir spring valves



E
lectronic control unit



S
ensors for regulating height and shock
-
absorbing functions


The adaptive shock
-
absorbing system A
DS is a fully automatic,
electronically controlled system which adjusts the shock
-
absorbers on
each wheel as required. Unlike a passive system with constant settings,
the vehicle is stabilised equally in all driving situations which improves
handling and l
eads to a perceptible calming of the body. If the response of
the body movement is low, the GL
-
Class drives at level 1. When the
speed of the body movement exceeds a certain level, the system goes
into the so
-
called skyhook algorithm and switches as needed

back and
forth between the second and third shock
-
absorbing levels using its fast
magnet valves in order to compensate the tilting and pitching motion of
the body. In more dynamic driving situations, level 4 is activated and in
the sport mode only level 4

is used. The regulation of each individual
wheel takes place almost immediately. Depending on the command
received, the valves can adjust to one of the characteristic curves
mentioned in less than 0.05 seconds.

The specific driving situation is recognised

by a steering angle sensor,
four turning angle sensors and the driving speed from the ESP® signal
and brake pedal switch. With the aid of these signals, the control unit
calculates the current shock
-
absorbing strength required and activates
the appropriat
e characteristic curve for the shock absorbing system. Via a

switch, the driver can preselect the required performance graph Sport or
Comfort manually.

In the new GL
-
Class an electromechanically supported Direct
-
Steer
system works with a variable steering

ratio which becomes perceptibly
more direct when the steering angle has an upwards trend. This gives the
driver better feedback from the road so that he does not need to work so
hard at steering. On the other hand, this also improves the handling and
resp
onse of the vehicle making it more fun to drive both on very winding
roads and in city traffic. In addition, electric steering gives speed
-
dependent steering support and thus provides clearly improved steering
comfort over the whole speed range.

Greater v
ehicle dynamics with load sensor system


as standard

A patent is pending for the new load sensors developed by research
engineers to improve driving dynamics even further. The system is able to
recognise various vehicle loads carried by the GL and with t
he data
received it is able to alter the regulating thresholds of the ESP®
accordingly. Up to now, the ESP® always presupposed a vehicle loaded
to the maximum with a complete roof load. The new load sensor system
now intervenes only when required by the ac
tual load carried and has a
positive effect on vehicle dynamics.

An effective sensor system within the air suspension system AIRMATIC
recognises the load situation at the time: The load carried by the vehicle
leads to alterations in the axle loads of the

front and rear axles. The
difference in pressure between the front and the rear axle serves here as
a reliable measurement for moving the height of the centre of gravity as
the wheel pressures determined by the AIRMATIC pressure sensors are
proportional t
o the wheel loads. The adjustment of the regulating
threshold is effected according to the wheel pressures determined; the
ESP
®
interventions are carried out more sensitively and according to the
actual load carried.

The ESP® adaptation takes place after d
riving a short distance. When the
vehicle starts driving, the load sensor system presumes that the vehicle is
fully occupied with a full load. This means that safest driving situation
possible is always guaranteed.

New driving dynamics system ACTIVE CURVE

SYSTEM

The optional active tilting stabiliser ACTIVE CURVE SYSTEM

can be
combined either with the air
-
suspension system AIRMATIC with the
adaptive shock
-
absorbing system (ADS) or with the ON&OFFROAD
package. The system
uses its active lateral stabilisers
on the front and rear
axles

to regulate them automatically depending on the lateral
acceleration, speed and position of the ADS Comfort/Sport switch. The
ACTIVE CURVE SYSTEM compensates the roll angle of the body when
driving round bends, thus providing a
greatly improved vehicle response
and more driving pleasure. At the same time, the system improves
handling and safety when driving at high speeds.
An improved ride both
driving round bends as well as on straight roads and increased scope when
driving off
-
road are among the other advantages of the ACTIVE CURVE
SYSTEM. Individually, the control strategies are
:



Improved vehicle dynamics achieved when
driving round bends

as
the starting torque and torque angle of the stabilisers are actively
influenced. Furthe
rmore, the starting torque of the stabilisers remains
constant even when exposed to one
-
sided activation, for instance
when driving over a pothole or round the outer periphery of a curve.
The varying regulation of the front and rear axles distributes the r
oll
moment variably so that under/oversteering characteristics are
adjusted to the individual driving situation. When driving on country
roads the handling is regulated so that it is particularly responsive and
on motorways so that it is especially stable.



In

extreme
off
-
road situations

at low speeds, both of the lateral
stabilisers are decoupled to allow an improved degree of axle
articulation.

A belt
-
driven hydraulic pump and an oil container in the engine
compartment together with one valve block each a
nd active stabilisers on
both front and rear axles are among the important components of the
active roll stabilisers. In comparison with a passive stabiliser, the active
stabilisers are divided in the middle and connected to each other by
hydraulic actuato
rs. Pressure sensors and a lateral acceleration sensor
use CAN signals to pass on the required information to the electronic
control unit for regulating the hydraulic pressure.

The ingenious ACTIVE CURVE SYSTEM uses its hydraulic system to
pump oil from th
e oil container into the system. The pressure regulator
integrated in the valve blocks of the front and rear axles and the
directional valves set the desired pressure and turn the active stabilisers
in the correct direction depending on the driving situati
on. The hydraulic
rotary actuator integrated in the active stabilisers has six oil
-
filled
chambers in its interior, and of these three are used to apply pressure for
each driving direction, i.e. left and right
-
hand curves. In addition, the front
valve bloc
k is responsible for distributing the oil flow between the two
axles independent of load.

No stopping the GL off

OFFROAD

driving program

Every GL
-
model has an extensive standard off
-
road package for going on
tours off the beaten track. In

addition to its permanent four
-
wheel drive
4MATIC and electronic traction control 4ETS, this includes an off
-
road
button which activates a special off
-
road driving program:



Slip threshold of the wheels and the switching points of the 7G
-
TRONIC PLUS are ra
ised to improve traction



Flatter characteristic curve for the accelerator allows it to be regulated
more sensitively



Off

In addition, the
START A
ssist and the HOLD function support the dri
ver
when starting off on a hill. The Downhill Speed Regulation (DSR)
automatically keeps GL
-
Class vehicles at the speed set using the
Tempomat lever.

Extended range of programs with ON&OFFROAD package

The ON&OFFROAD package for the new GL
-
Class with its si
x driving
programs improves both vehicle dynamics and handling safety as it
provides the best drive control available for very varying operating
conditions both on and off
-
road. There is a perceptible improvement in
comparison with the Offroad
-
Pro Technik
package which has been on
offer for the G
-
Class up to now. Up to now there was one top driving
program for on
-
road driving and one for going cross
-
country. The new
package has one automatic program, two special off
-
road programs and
three road programs at
its disposal. The specific driving programs for
four
-
wheel drive provide the solution to the conflicting aims which have
made life difficult up to now for the further development and research of
the 4MATIC, the electronic traction system 4ETS as well as ES
P
®

and
ASR. For instance: On off
-
road tracks it is important that the control
systems regulate very gently because of the low friction values


but that
makes it almost impossible to have a sporty tuning On the other side of
the coin, a sporty basic tuning

situation. However, the new ON&OFFROAD package with its six specific
driv
ing programs allows both vehicle dynamics and handling safety to be
optimised even more for every driving situation.

The programs are activated via a rotary switch on the central console. At
the same time AIRMATIC, ADS, drivetrain and electr
ic
steering are

adjusted to suit the specific requirements. The six driving programs are:



Automatic

Despi
te the diversity, the driver is always in the position to make the right
decision: It is easy to select the right program, the program selected is
shown in the multifunction display in the instrument cluster as well as
almost photo
-
realistically visualised

on the COMAND screen. If the driver,
for example, selects the program 'Winter', the display shows the GL
-
Class
in snow; the program 'Sport' shows a racing track with red
-
white kerbs,
'Offroad 1 and 2' show cross
-
country formations with different contours.

The depiction shown is also interactive: the steering angle and spring
travel correspond to the real values. In addition the display gives
additional information about the steering, climbing and tilting angles, the
AIRMATIC level, the pre
-
selected speed f
or driving downhill (Downhill
Speed Regulation, DSR) and the selected drivetrain settings with
reduction gear and lock.

Reduction gear, DSR or the AIRMATIC level control system can all be
selected individually regardless of the drive program chosen. Just

as with
the basic settings for the ON&OFFROAD package, the driver cannot
make a mistake here either. Settings which are not logical and which
have a negative influence on the handling of the vehicle, its safety or
traction, are excluded. If there is any d
oubt, the automatic mode is
activated.

From the "hardware" point of view, the ON&OFFROAD package comprises

A perceptible improvement in riding comfort with a simultaneous reduction


in the weight of the vehicle by 90 kg has been achieved by using
innovative approaches. In this way the new GL
-
Class and all current
automotive developments at Mercedes
-
Benz have made their farewells to
an old conflict

of aims: Up to now, any increase in comfort has been at the expense of
the vehicle's weight. The plastic engine support, the rigid cockpit cross
beam
made of high
-
streng
th magnesium alloy

or the electr
ic
steering are
among the outstanding examples of the "weight
-
optimised increase in
comfort". The highly insulating front windscreen and the optional side
windows using multilayer glass technology give much better sound
insu
lation, but weigh less than conventional multilayer glass. The weight
savings on the axles and alloy wheels are also extremely impressive. The
weight per axle is reduced by 18 kg by using high
-
strength aluminium
alloys. In this way the "unsprung mass"


a
decisive parameter with
respect to comfort


is reduced. The lower the weight of the wheels and
axles, the less they are activated when driving over potholes or uneven
surfaces. As a result, suspension and shock absorbers are not required to
work as hard f
or a calming effect. So, to put it simply: A reduction in wheel
suspension activation and the ensuing calming means a more
comfortable ride.

While looking for other ways of increasing riding comfort, the engineers
made a find in the GL roof. Up to now, the

automatic tailgate was
operated by a hydraulic drive situated at the rear in the upper frame of the
roof. In the new model, the hydraulic system has been replaced by an
electric spindle. This may save "only" two kg, but they have a significant
effect on t
he handling as weight
-
saving measures on the roof of a vehicle
way above the centre of gravity are much more effective than comparable
weight reductions, for instance on the underbody.

Passenger compartment encloses occupants like a protective
cocoon

In a frontal crash, the front
-
end assembly can absorb impact energy and
thus attenuate the peak loads on the occupants. The front
-
end structure
essent
ially comprises two straight front longitudinal members, a second
upper longitudinal
-
member plane and a

subframe that supports the drive
unit, connects the structure's two halves and deforms when subjected to
high frontal impact loads. The lateral connecti
ons in the front
-
end activate
the side opposite of the impact point in offset frontal impacts. The long
front
-
end, short V
-
engines and the articulated shaft with its deformation
element also contribute to the front
-
end assembly's deformation potential.
In
the event of major deformations, the wheels are supported against the
strong bulkhead. The bulkhead itself is reinforced by an exterior cross
member
resting against

the A
-
pillars above the pedal floor.

The passenger compartment's strength is tailored to th
e deformation
resistance of the front
-
end assembly and envelops the occupants on all
seven seats like a protective cocoon. The outstanding rigidity and
strength result in part from the floor system with its separate transmission
tunnel and longitudinal mem
bers integrated into the sidewall that,
together with cross members set onto the floor, form
s

a stable supporting
structure. The high
-
strength sidewall assembly comprises the body pillars,
the lateral roof frame and the lateral longitudinal members. The si
dewall
assembly's outer shell is formed by the outer panelling. The inner shells
are partially made up of several components with large
-
surface nodes
between the pillars, roof frame and lateral longitudinal members.

The dual
-
shell A
-
pillar with its maximu
m
-
strength interior reinforcement is
stabilised along the transverse line by the front roof frame and various

cross members. The latter are located in the area beneath the
windscreen, above the pedal floor and below the dashboard. An effective
protection c
oncept has also been implemented to account for rear
impacts. Long deformation paths thanks to box

the rear axle and of the filler neck above the rear axle provide a high
energy abs
orption capacity in the event of rear
-
end collisions.

The GL
-
Class also provides the greatest

possible protection for more
vulnerable traffic participants such as pedestrians and cyclists. Besides
the yielding areas of the front
-
end, the folding exterior m
irrors and the
smooth contours, the risk of suffering injury from impact with the vehicle
has been reduced through modif
ying

the bonnet and increas
ing

the
distance to the components in the engine compartment. In addition, the
active bonnet is a standard fe
ature. It has the potential to reduce the
severity of any injuries suffered by an impacting pedestrian or
cyclist

and
further increases the deformation space. To optimise trigger criteria
detection, acceleration sensors have been additionally integrated in
to the
front bumper.

The GL
-
Class easily meets new crash requirements

In developing the GL
-
Class, the test specifications and criteria for
accident testing applied in
-
house went far beyond those required by law.
The GL was therefore perfectly able to fulfi
l even the most stringent
requirements of the most important international test institutions:



Frontal collisions:


New full
-
width front impact in accordance
with




US
-
NCAP (US New Car Assessment
Program)



Side impact:


New mast impact in accordance with






Euro
-
NCAP

(European New Car Assessment Program)

New side impact in accordance with US
-
NCAP



Roof strength:


New roof strength test in accordance with
IIHS

(Insurance Institute for Highway Safety)



Pedestrian protection:

-
NCAP


Thanks to its comprehensive protection concept, the GL
-
Class has the
potential to achieve excellent marks in all international crash ratings.

Assistance systems act as "electronic crumple zone"

Further optimisation of driving and condition safety i
n the new GL
-
Class is
provided primarily by the numerous assistance systems' capacity to pre
-
empt accidents by acting as an "electronic crumple zone".

In addition to the driving dynamics control systems ESP
®

and 4ETS, the
GL
-
Class comes as standard with t
he electronic brake control system
ADAPTIVE BRAKE that improves traction, driving safety and operating
comfort. The ADAPTIVE BRAKE electronic brake control system
comprises the basic anti
-
lock braking (ABS) function and anti
-
slip
regulation (ASR) as well a
s GMR active yaw control. ABS and ASR
primarily monitor and affect longitudinal dynamics while GMR controls
lateral driving dynamics. Where critical driving conditions are detected,
and where physics will allow, selective wheel braking and engine torque
ad
justments are applied in order to

maintain or recover traction and
driving stability. In addition, ADAPTIVE BRAKE communicates with all
other assistance systems and further comprises the following functions as
standard:

severity reduced, with the aid of radar
-
based safety systems such as
collision warnings and adaptive brake assistants. This has been shown by
the detailed analyses performed by Mercedes
-
Benz accident research. It
is here
that experience with the Mercedes
-
Benz innovations DISTRONIC
PLUS and BAS PLUS pay off. With the GL
-
Class,
an
SUV will now
feature such a system for the first time: COLLISION PREVENTION
ASSIST*. Unlike conventional systems, this new brake assistant is not
merely a pure
ly

urban
-
driving system designed to minimise trifling
damage. The innovative solution
aims
instead to
provide
protect
ion

against typical rear
-
end collisions in all traffic situations. The company
expects the collision warning system to have a
significant

and

positive
effect on accident occurrence statistics. Test
result
s

underscore this
assessment: in simulator tests with drivers, COLLISION PREVENTION
ASSIST was shown to reduce the accident rate in three typical accident
scenarios from forty
-
fo
ur to eleven percent.

* Country

specific standard equipment

COLLISION PREVENTION ASSIST issues visual and audible warnings
when detecting obstacles to drivers who may be distracted and prepares
the brake assistant
to

apply the
brake
s as precisely

as possi
ble. This
brake application is then triggered as soon as the driver exerts pressure
on the brake pedal. The system also meets the fundamental "Forward
Collision Warning" requirements of the US National Highway Traffic
Safety Administration (NHTSA) and is c
apable of:



Identifying the distance to the vehicle in front as too low in a speed
range from 30 to 250 km/h.



Detecting a reduction in distance. Where there is a risk of collision,
the driver receives a visual and audible warning.



Detecting stationary obsta
cles along the path of motion and issuing
corresponding warnings.



Identifying specific driving situations, such as driving in queued traffic,
and adapting the trigger threshold for warnings and the adaptive
brake assistant accordingly.

possible use of the
remaining distance. This inherently increases a following driver's
chances of himself avoiding a rear

vehicle in front accelerates, brake pressure is returned to the degree
requested by the driver; if the distance to vehicles driving or stopping
ahead drops, brake pressure is increased even further.

or belt tensioners.


In the extreme range of driving physics, drivers are also aided
substantially by a number of systems, including the steering assistant
which, for instance, helps the driver
by applying steering torque to the
steering wheel when the vehicle oversteers. An innovation and a highlight
in the new GL is the standard Crosswind Assist, which uses targeted
brake application to aid the driver when driving
in

high transverse wind
force

conditions,
thus increas
ing

the perception of safety and comfort.

Stability even in sudden crosswind gusts

The driving situation is well
-
known: when driving on high
-
quality country
roads or dead straight stretches of motorway, the occupants suddenly
perce
ive a forceful blow from the side, for instance when overtaking a
truck, driving onto a bridge or at the end of lateral constructions such as
noise abatement walls. The vehicle has been hit by a crosswind gust.
Drivers of the new GL need not fear such
gust
s of
crosswind as the
driving dynamics control systems reliably compensate for these
meteorological assaults and keep the vehicle firmly on course. Depending
on the direction and intensity of the crosswind, the control systems apply
corresponding brake pre
ssure to the wheels and compensate, or at least
substantially mitigate, the wind's effects on the vehicle. The intervention
manoeuvre is handled by ADAPTIVE BRAKE. The required information is
supplied by the sensors of the Electronic Stability Program ESP
®
, the
AIRMATIC ADS air suspension and the electromechanical steering.

If the system identifies a necessity to intervene, the driver is assisted
through brake application
on

the front and rear wheel on the upwind side.
This intervention results in a steerin
g effect that reduces the impact of the
crosswind. Crosswind Assist is active when driving straight ahead or
through light bends at a speed of 80 km/h or more. The driver always
remains in control: in the case of substantial and/or rapid steering
correctio
ns, Crosswind Assist is automatically suspended. The system
filters minor crosswinds and only becomes active at a certain threshold.

Continuous, constant crosswinds are also ignored. Research has shown
that the latter driving situation affects comfort and
perceived safety far
less and is intuitively compensated for by drivers.

Back on track with the steering assistant

The standard steering assistant becomes active whenever the assistance
systems identify unstable driving conditions that can be eliminated
t
hrough simple steering actions. The system determines a steering torque
corresponding to the driving condition and applies this torque through the
electric power steering. When oversteering


the vehicle's rear creeping
toward the outer edge of the corner


the steering assistant requests the
driver to countersteer via the steering wheel until the vehicle has once
again stabilised. The second primary feature is assistance when braking
on a surface that displays different friction coefficients on the right a
nd left
of the vehicle, as is the case for example on partially iced
-
up
carriageways in winter. The steering assistant notifies the driver of the
direction in which the steering wheel should be turned in order to
neutralise the yawing impulse. Even if the
driver ignores the steering
assistant's recommendations, ample reserves remain to stabilise the
vehicle in the form of the driving dynamics systems such as ADAPTIVE
BRAKE, ESP
®

or 4ETS. The steering assistant is always available to
provide the driver with
recommendations
,

but never takes over.

Even after a crash: occupant protection

After a more substantial crash, the hazard warning lights are switched on
automatically in order to warn the surrounding traffic. At the same time,
the door locks are automatic
ally disengaged in order to facilitate the best
-
possible access to the vehicle occupants for emergency services. Thanks
to the partial opening of the side windows, the interior is more efficiently
ventilated after restraint systems have triggered.

Where a

collision is detected, the central control unit shuts off the fuel
system. After determining the cylinders' positions, the engine
management opens the injectors on cylinders not in compression stroke
and relieves the fuel high
-
pressure area by releasing t
he remaining fuel
directly into the combustion chambers. This reduces the risk of fuel
escaping.
As a further measure t
o prevent fuel from escaping, the
relevant points feature cut
-
proof fuel lines

and this

in the event of a collision
.

If COMAND Online is chosen for the new GL
-
Class, the automatic
Mercedes
-
Benz emergency call is included as standard. In the event of a
serious accident, emergency services are notified automatically and
within minutes are furnished with extensive informa
tion on the precise
accident location or the respective vehicle model. The operating principle:
if airbags or belt tensioners are triggered in a crash and COMAND Online
is connected to a mobile phone, the system transmits the vehicle's
precise GPS location

and its chassis number (VIN) to both the emergency
services and the Bosch Communication Center's service control room by
text message. The location data is also transmitted by DTMF (dual
-
tone
multi
-
frequency). Even if the occupants are unconscious or do n
ot know
their precise location, for example
when

on holiday, the emergency
services called by the Communication Center can be informed precisely
and rapidly.

The vehicle also quickly establishes a voice connection to the Bosch
Communication Center. The la
nguage used does not correspond to the
