Mercedes-Benz Press Release
The epitome of luxury coupes
With stylish, eye-catching design, exclusive appointments and
cutting-edge technology, the extensively updated 2011
Mercedes-Benz CL-Class underscores its flagship position in the
world of refined automobiles. Powered by a new 429-hp V8 biturbo
engine which achieves a 10-15% improvement in fuel economy and
23% improvement in CO2 emissions, the CL550 4MATIC opens a new
dimension of efficiency in the luxury coupe segment. This
significant reduction is achieved thanks to the newly-developed
BlueDIRECT technology with third-generation spray-guided direct
injection, energy-efficient control of alternator, fuel pump,
air-conditioning compressor and power-assisted steering system.
It also features the use of low rolling resistance tires and, on
the CL600, the energy-optimized Active Body Control system. In
addition, the Mercedes-Benz developers equipped the CL-Class
with state-of-the-art multimedia technology, thus helping this
model retain its position as the epitome of quality in its
class. The 2011MY CL-Class will make its U.S. debut in Autumn of
2010.
With the new generation of the CL-Class, Mercedes-Benz is
emphasizing fuel consumption and exhaust gas emissions in this
exclusive high-end segment. According to Dr Dieter Zetsche,
Chairman of the Board of Management of Daimler AG: "The CL is
the ideal ambassador for our brand. It combines in a particular
degree those things that characterize Mercedes-Benz:
fascination, perfection and responsibility. And with the new
generation we have gone a step further, too – especially in the
realm of efficiency. But in terms of design, safety, comfort and
output, too – the CL shows the way forward: simply follow
Mercedes."
In the realm of safety, a combination of cutting-edge camera and
radar-based assistance systems - unique in the luxury coupe
segment - including the innovation of the Active Lane Keeping
Assist and Active Blind Spot Assist systems, makes the CL-Class
a "thinking" partner of the driver. The modified Active Body
Control (ABC) with crosswind stabilization system and the
Direct-Steer system also contribute to enhancing safety and
driving enjoyment.
Design: a muscular, confident presence
The exterior appearance of the new CL-Class is characterized by
the taught profile of the hood, the dynamic V-shape radiator
grille and the curving headlamps – design details that
discreetly but effectively emphasize the car's elegant yet
powerful lines.
The front bumper presents a new three air intake design accented
with a prominent chrome trim strip. An LED strip with chrome
surround for the daytime running lights is elegantly integrated
in the side openings for the brake cooling air. With standard
Bi-Xenon Headlamps with active curve illumination and Adaptive
Highbeam Assist, the headlamps offer state-of-the-art
illumination. LED turn indicators and position marker lamps
round off the car's advanced image while the rear of the vehicle
is characterized by the newly-designed tail lamps.
New V8 bi-turbo engine with innovative technology
The new-generation CL-Class also assumes a pioneering role with
its drivetrain. Under the hood of the CL550 4MATIC a new V8
biturbo engine with BlueDIRECT technology delivers impressive
power. With its 4663 cc displacement, the eight-cylinder engine
produces 429 hp so that despite 0.8 liters less displacement, it
is still around 12 percent more powerful than its predecessor,
which had an output of 382 hp. At the same time, torque was
raised from 391 lb-ft to 516 lb-ft – an increase of 32 percent.
The new engine achieves a 10-15% improvement in fuel economy and
23% improvement in CO2 emissions. The CL5550 4MATIC requires a
mere 4.9 seconds to accelerate from a standstill to 60 mph
(previous model: 5.4 seconds). Summing up: the CL550 4MATIC is
significantly more agile, torquey and thriftier than its
predecessor.
The BlueDIRECT technology package of the V8 biturbo includes a
series of new developments, unique in their combination. Worthy
of mention among these is the third-generation spray-guided
direct gasoline injection with piezo injectors and multi-spark
ignition with up to four ignition sparks within a millisecond.
Together both enable an innovative combustion process called
"homogenous split". Other factors contributing to the exemplary
low fuel consumption continue to be the consistent use of
friction-optimized pistons, piston rings and cylinder barrels,
the on-demand control of oil pump and the new three-phase
thermal management in the coolant circuit. The luxury coupes
also controls the alternator depending on the type of driving
and on-board voltage. Kinetic energy is recuperated in the
overrun mode.
The CL600, with its 510 hp 12-cylinder biturbo engine and 612
lb-ft. of torque remains the top-of-the-line model: it
accelerates the luxury coupé from a standstill to 60 mph in a
breathtaking 4.5 seconds.
A unique combination of driver-assistance systems
The 2011 CL-Class further enforces its position as an automotive
masterwork and a technology platform with the most advanced
assistance and protection systems. These highly perceptive
assistants convert the coupe into a "thinking" partner that can
see, feel and react instantly if it detects a hazard, acting
autonomously to prevent accidents or to mitigate their effects.
The trailblazing driver assistance systems in the CL-Class are
based on state-of-the-art radar, camera and sensor technology.
Active Lane Keeping Assist is a new safety feature making its
debut on the CL-Class as part of the optional Driver Assistance
Package. If the vehicle threatens to cross a continuous lane
marking line, the system actuates an electric motor in the
steering wheel, causing it to vibrate briefly – giving the
driver a discreet but effective warning hint to countersteer
immediately. The active system springs into action if the
Mercedes coupe unintentionally crosses a continuous lane marking
line to the right or to the left. In this case, the car
intervenes by gently braking the wheels on the opposite side of
the car, helping the driver to stay in the lane. Active Lane
Keeping Assist is built upon the existing ESP® Electronic
Stability Program.
Active Lane-Keeping Assist evaluates information provided by a
camera mounted on the inside of the windshield. It identifies
the contrast between the road surface and the lane markings. In
addition, the optional radar system scans the side of the
roadway for dividers and other roadway edge markings. The system
also evaluates the driver's actions and can reliably determine
whether the car is departing from the lane intentionally or not.
For instance, there is no warning if the driver accelerates hard
just before passing or when accelerating onto a highway, or if
he brakes hard or steers into a curve.
Targeted brake actuation: Active Blind Spot Assist
Another innovation Mercedes-Benz offers for the CL-Class is
Active Blind Spot Assist, a system that makes use of a
multi-stage warning concept. If the system detects that a lane
change would be too dangerous, it warns the driver by displaying
a red triangle in the glass of the exterior mirror. Close-range
radar sensors monitor the area immediately to the side and to
the rear of the car. If the driver disregards this warning and,
for example, uses the turn indicator, an audible warning also
sounds. If the driver continues to ignore the warnings and comes
dangerously close to a vehicle in the neighboring lane, the
system acts: a corrective braking intervention via ESP® is
applied to the wheels of the opposite side of the vehicle. This
causes a yaw movement about the car's vertical axis due to the
unequal distribution of the braking forces. If an accident still
cannot be avoided, the active Blind Spot Assist system can
reduce the consequences of a collision through the brake
actuation.
Assistants to see and be seen better
The Adaptive High Beam Assist system is now offered as standard
equipment on the CL-Class. This camera-based system can
recognize oncoming vehicles or vehicles ahead with their lights
on, and then softly transitions from high-beam to low beam to
create the best possible lighting conditions without dazzling
other drivers. In addition, Mercedes-Benz offers the optional
Night View Assist PLUS system for the CL-Class, featuring a
special infra-red camera for pedestrian detection: pedestrians
are now specifically highlighted in the display, to help alert
the drivers in low light conditions.
On European models, the images supplied by the
windshield-mounted camera are also used by the new, optional
Speed Limit Assist (not available in the U.S.), which recognizes
speed limit signs in passing and shows the relevant speed limit
in the central display and on the navigation system's map
display.
For the new-generation CL-Class, Mercedes-Benz has also improved
the long and medium-range radar used by Brake Assist (BAS PLUS)
and DISTRONIC PLUS proximity cruise control.
An "electronic crumple zone": the PRE-SAFE® Brake
Mercedes-Benz offers another radar based system for the luxury
coupé as a component of the Driver Assistance Package: PRE-SAFE®
Brake with automatic emergency braking. If the driver is
distracted and fails to recognize the imminent danger of a
rear-end collision or the warning signal of an assistance
system, PRE-SAFE Brake can intervene and autonomously apply
partial braking. If the driver fails to react even after
automatic, partial braking action, this new version of PRE-SAFE®
Brake activates maximum braking pressure around 0.6 seconds
before an unavoidable collision – this emergency braking action
can significantly mitigate the severity of the impact. The
PRE-SAFE® Brake thus acts as a kind of "electronic crumple
zone".
ATTENTION ASSIST Warns Drowsy Drivers:
Drowsiness is one of the most common causes of accidents. This
is why Mercedes experts have developed the ATTENTION ASSIST
system which forms part of the standard equipment of the new
CL-Class. The system continuously monitors more than 70
different parameters in order to identify driver drowsiness and
provides a warning before the dangerous microsleep phase begins.
Observing the driver's steering behavior has proved to be a
particularly strong indicator: several years of practical
research by Mercedes-Benz have shown that drowsy drivers make
minor steering errors which they often correct very rapidly in a
characteristic way. This steering behavior is recognized by a
special steering angle sensor. Observing the driver's eyes
cannot always provide conclusive evidence of sleep since many
drivers can experience micro-sleep with their eyes open.
Active Body Control reduces the effect of a crosswind
The CL-Class also meets the highest standards in terms of
driving dynamics and agility. This is in part thanks to
Direct-Steer, which can vary the steering ratio based on the
steering angle, and modified Active Body Control (ABC) with
crosswind stabilization (standard on the CL600, CL63 and CL65
AMG). This latest stage in active body development modifies the
wheel load distribution via the ABC spring struts within
milliseconds (depending on crosswind direction and intensity) to
help compensate for crosswind forces.
The Active Body Control suspension system – which ushered in new
dimensions of driving dynamics in the preceding CL-Class in 1999
- is unique worldwide as it not only regulates roll, but
pitching and squatting movements as well, ensuring a perfect
harmony of comfort and handling stability. Since the
introduction of this innovative system, engineers in
Sindelfingen have continuously refined it, so that eleven years
later it still marks the pinnacle of automotive engineering. In
addition to crosswind stabilization, the new suspension features
an energy-optimized hydraulic pump that takes part of the burden
off the engine, contributing towards reducing fuel consumption.
Additional safety and agility during spirited driving is
provided by the standard Torque Vectoring Brake in the new
CL-Class – targeted, one-sided braking intervention at the
inside rear wheel when cornering. This enables the luxury coupe
to turn into the bend under precise control with even greater
agility.
On-board infotainment: the most advanced multimedia technology
In line with its serene character and sophisticated technology,
the CL-Class also sets standards for onboard infotainment. The
latest innovation, SPLITVIEW technology, is optionally available
for the COMAND system centrally located in the center console.
This innovative display concept allows the driver and front
passenger to view different contents simultaneously on the same
screen. For example, while the driver uses the map-based
navigation system, the front passenger can watch a DVD.
The standard COMAND control and display system with Bluetooth®,
USB and SD card interfaces offers customers the possibility of
exporting their stored data to other vehicles and multimedia
devices. It is also possible to transfer and update navigation
data. Mercedes-Benz integrates the Media Interface – an
interface for mobile audio and video devices – via an auxiliary
cable located in the glovebox. Standard audio equipment also
includes radio, a 6-disc CD/DVD player with MP3 function, an
equalizer with speed-dependent volume control and the 7.2 GB
MUSIC REGISTER which stores around 2,500 digital music files in
MP3, AAC or WMA format. The system recognizes music files played
on CD, DVD or from the MUSIC REGISTER using its stored
Gracenote® database, and shows the title, album and performer in
the color display. The new Music Search function enables
passengers to search SD memory cards, USB sticks, CDs and DVDs
for specific music titles and performers.
The standard Navigation system features a nationwide map system
stored on a 40-Gigabyte hard disk, enabling extremely rapid
route calculation. Another factor contributing to a high level
of navigation ease is the detailed 3-D map display with SIRIUS
real-time traffic information.
The standard Voice Control system allows the driver to operate
the navigation, telephone and audio devices via whole-word input
-- meaning the driver no longer needs to spell out his commands
but simply speaks whole words when entering the destination,
choosing a radio station or a music title from the Music
Register, or when calling up a name from the phone book.
Co-developed by Mercedes-Benz and Harman Kardon® surround sound
system with Discrete Logic7® technology delivers an outstanding
performance with three-dimensional sound.
Interior: carefully selected materials and first-class finish
In the interior, too, Mercedes-Benz developers and designers
perfected the
CL-Class, paying careful attention to detail. A total of four
different kinds of fine wood open up the possibilities for
perfectly matched material and color concepts: a choice of light
or dark high-gloss burl walnut, black ash and high-gloss brown
poplar on the CL600. Important to note: in accordance with
Mercedes-Benz' corporate philosophy of sustainability, the
CL-Class uses only European wood from renewable forestry
sources. Most of the wood components are hand-made and matched
individually for color and grain by experienced craftsmen.
The seating materials found in the new CL-Class are of the most
exquisite quality. There is a choice of four tasteful color
combinations for the vehicle interior: black premium leather,
savanna/cashmere premium leather, ash/grey premium leather,
sahara beige/black premium leather.
The multifunction wood/leather steering wheel of the CL-Class
has also been modified by the Mercedes-Benz designers: the rim
and airbag module are lined with soft nappa leather as standard.
The new, flatter airbag module also lends a sporty touch to the
multifunction wood/leather steering wheel sewn with
sophisticated double stitching.
Apart from this, Mercedes-Benz makes more use of light as a
styling element in the vehicle interior. Standard ambient
lighting provides a choice between three lighting moods: solar
(amber), neutral (white) and polar (ice blue).
Tradition: an exclusive line of ancestors
The new generation CL-Class continues the great tradition of
Mercedes-Benz coupes, which reaches back to the legendary
supercharged cars of the 1920s and '30s. Since the 1950s
Mercedes-Benz has produced an uninterrupted series of exclusive
two-door cars which combine sophisticated design with
trailblazing technology – every model an automotive classic. The
W 188 model series 300 S Coupé -- which entered series
production in 1952 -- marked the beginning. A contemporary
report called it the "measure of what it is possible to achieve
in automotive engineering".
This statement has remained true for all subsequent models,
right down to the current CL-Class, because the luxury coupes
from Mercedes-Benz featured - apart from their timeless design
and the highest level of comfort - trailblazing innovations in
automotive technology. Thus it was that in 1961 the 220 SE Coupé
was the first series-production Mercedes-Benz to be equipped
with disc brakes. In 1995 the ESP Electronic Stability Program
celebrated its world premiere in the S 600 Coupé of the C140
model series, and in 1999 the Active Body Control suspension
system was introduced for the first time in the C215 model
series CL-Class. The technological innovation PRE-SAFE® brake
made its debut in a large Mercedes-Benz coupé. Now two new
developments in the 2011 CL-Class, Active Lane Keeping Assist
and the Active Blind Spot Assist, will help prevent accidents or
reduce their severity.
