World premiere of the Vision CLS Coupé study
and the new SLR McLaren high-performance sports car
The Mercedes presentation at the 60th Frankfurt Motor Show is a fitting
occasion for two automobiles that set standards in both design and
technology, thereby emphasising the role of Mercedes-Benz as the pacemaker
and innovative leader among car brands: the Vision CLS and the SLR
McLaren high-performance sports car.
The Vision CLS continues a series of extraordinary, pioneering car
concepts with which Mercedes-Benz has repeatedly set trends in previous
years. Never before have two different characters been combined as
specifically and beautifully as in this design study, where the stylistic
excitement of a coupé harmonises with the comfort and functionality
of a saloon. "We are one coupé generation ahead with the
Vision CLS", says Professor Jürgen Hubbert, the member of
the Daimler-Chrysler AG Board of Management responsible for the Mercedes
Car Group. "The idea of a four-door coupé opens up interesting
possibilities, and is especially intended to appeal to people for
whom cars and driving are a passion."
The new SLR McLaren high-performance sports car is being presented
to the public for the first time in Frankfurt as an exciting synthesis
of legend and innovation. This modern "swing-wing", which
continues the legend of the SLR gullwing racing sports cars from the
fifties, is equipped with a 460 kW/626 hp supercharged V8 engine which
catapults the two-seater from standstill to 100 km/h in just 3.8 seconds.
Like the Formula 1 racing cars the SLR has a carbon-fibre body which
combines low weight with exemplary energy absorption for the greatest
possible occupant safety.

Vision CLS: Coupé with the comfort and space of a saloon
A unique synthesis between a coupé and a saloon has produced
the Vision CLS, a car whose elegant lines arouse instant enthusiasm
and which exhibits all the typical Mercedes characteristics in terms
of safety, innovation and comfort - a perfect combination of enthralment
and good sense. The same applies to the powerful diesel engine, whose
195 kW/265 hp provides excellent conditions for a dynamic driving
experience. It accelerates the Vision CLS from zero to 100 km/h in
only 6.4 seconds, the maximum speed being electronically limited to
250 km/h. Despite this impressive performance the six-cylinder engine
is happy with 7.5 litres of fuel per 100 kilometres (NEDC overall
consumption) and meets the stringent EU-4 exhaust emission limits.
"The combination of outstanding performance, a low fuel consumption,
EU-4 compliance and a diesel particulate filter illustrates the great
potential still remaining in this ultra-modern six-cylinder biturbo
diesel, and in diesel engines in general", Professor Jürgen
Hubbert explains.
As in the case of other studies and show cars with which Mercedes-Benz
has repeatedly presented new and interesting vehicle concepts for
open discussion - and which have usually entered series production
- the project planners are once again using the Frankfurt Motor Show
to gauge the opinions of visitors to the show, and will reach their
decision for this unique vehicle concept according to the public response.

With four doors and a generously dimensioned interior the Vision CLS
offers a significant improvement in comfort and functionality compared
to other coupés. The distance between the front and rear seats
is 829 millimetres, and therefore at the level of a saloon. The 470-litre
boot capacity (VDA measuring method) of the Mercedes study also considerably
exceeds the figures for other coupés and many a saloon.
The coupé study is equipped with pioneering Mercedes innovations
such as adaptive front airbags, windowbags and sidebags, as well as
belt tensioners and belt force limiters for all seats, giving it the
same high safety standard as the Mercedes luxury class. Active headlamps,
cornering lights and the electrohydraulic braking system Sensotronic
Brake Control (SBC) are other special technical features of
the Vision CLS.
Mercedes-Benz has combined the high-torque biturbo engine with the
new 7G-TRONIC, the world's first seven-speed automatic transmission
for passenger cars. This offers a high degree of gearshift comfort
while allowing fast mid-range sprints, so it harmonises particularly
well with the dynamic character of the coupé study.

SLR McLaren: top technology for the Gran Turismo of the 21st Century
With the new Mercedes-Benz SLR McLaren, which celebrates its world
premiere at the Frankfurt Motor Show, Mercedes-Benz and its Formula
1 partner McLaren are demonstrating their long years of experience
in the development and production of high-performance sports cars.
This two-seater with its striking swing-wing doors and stylistic elements
of the Formula 1 Silver Arrows continues the legend of the SLR racing
sports cars from the 1950s.
The Gran Turismo for the 21st Century consists almost entirely of
carbon-fibre materials (CRP). This lightweight but at the same time
extremely rigid material is a product of aerospace technology and
finds widespread use in modern Formula 1 racing cars. This high-tech
material is approx. 50 percent lighter than steel. Moreover, during
an impact carbon fibres exhibit four to five times the energy absorption
of steel or aluminium. Mercedes-Benz makes use of these characteristics
and installs two 620 mm long side members of carbon fibre in the front-end
structure of the new SLR, which absorb the entire crash energy during
a defined impact. This allows the passenger cell, which is also of
CRP and therefore offers a very reliable survival space even during
a lateral or rear impact, to remain substantially undamaged. Adaptive
airbags, newly-developed knee and sidebags and belt tensioners round
off the safety features.
Mercedes-Benz also employs a new materials technology when manufacturing
the brake discs. These are of fibre-reinforced ceramics and not only
have a high fade resistance and very long operating life, but also
produce outstanding deceleration values in conjunction with the electrohydraulic
braking system Sensotronic Brake Control (SBC), impressively
underlining the racing car nature of the Mercedes-Benz SLR McLaren.

460 kW/626 hp V8 engine with the latest supercharger technology
In the interests of perfect handling dynamics and a high level of
braking stability the new Mercedes-Benz SLR McLaren was designed as
a sports car with a front-mid engine. The powerful V8 engine mounted
on a robust aluminium frame has a low installed position to ensure
the low centre of gravity which is desirable for handling agility.
The supercharged 5.5-litre engine develops an output of 460 kW/626
hp and a maximum torque of 780 Newton metres from 3250 rpm, maintaining
this over a wide engine speed range up to 5000 rpm. This makes the
SLR's eight-cylinder unit one of the most powerful engines to be found
in a roadgoing, series-production sports car. The SLR McLaren accelerates
from standstill to 100 km/h in just 3.8 seconds, reaches the 200 km/h
mark after only 10.6 seconds and registers 300 km/h only 28.8 seconds
after starting from rest. Its maximum speed is 334 km/h.
The standard five-speed automatic transmission is configured for this
outstanding performance. It offers the driver a choice of three drive
programs with different gearshifting characteristics. In "Manual"
mode the five speeds can be selected either via buttons on the steering
wheel or by the Touchshift feature on the automatic shift lever. In
this program the driver is also able to choose between three shift
stages - "Sport", "Supersport" and "Race"
- for even faster gearchanges when driving briskly.
Aerodynamics concept based on Formula 1 know-how
In order to meet the extreme high-speed handling, stability and air-cooling
requirements for such a high-performance sports car, Mercedes-Benz
has developed a highly sophisticated aerodynamics concept in collaboration
with McLaren. This ensures exemplary road contact and therefore the
handling safety typical of a Mercedes. As a result of extensive wind
tunnel tests, the Mercedes-Benz SLR McLaren is equipped with an almost
completely smooth underfloor and is fitted with a special six-channel
diffuser under the rear end. Both are well-proven design principles
adopted from Formula 1. They ensure a practically unimpeded airflow
beneath the vehicle to produce what specialists refer to as "negative
lift " at high speeds.
A retractable spoiler at the rear of the SLR creates an additional
downforce. When the car reaches a speed of 95 km/h the spoiler automatically
extends into the slipstream at an angle of ten degrees and increases
the downward pressure acting on the rear axle. The spoiler also acts
as an airbrake when required: if the driver brakes heavily it pivots
to a 65-degree angle, not only increasing wind drag but also shifting
the aerodynamic centre of gravity further to the rear. This gives
the SLR outstanding stability when braking from high speeds.

Premiere of the 4MATIC permanent four-wheel drive system in the
E-Class
Other new Mercedes products celebrating their premiere at the Frankfurt
Motor Show include the 4MATIC variants (Saloons and Estates) in the
E-Class. By interacting intelligently with the standard Electronic
Stability Program ESP® and the 4ETS traction control system, 4MATIC
helps the driver to manage critical situations safely and confidently.
From autumn 2003 the six-cylinder models E 240 and E 320 will be available
with 4MATIC, as is the eight-cylinder E 500.
In addition to the interaction between ESP® and 4ETS the new four-wheel-drive
models in the E-Class feature another technical highlight - Sensotronic
Brake Control (SBC) - which first entered series production
at Mercedes-Benz. Thanks to variable brake force distribution at each
wheel this provides more safety when braking on bends, while increasing
the efficiency of Brake Assist, the Electronic Stability Program ESP®
and 4MATIC by virtue of its dynamic intervention and precision. Braking
impulses become even more sensitive and rapid.
A new entry to the E-Class range is the E 500 Estate, which has a
powerful V8 petrol engine generating an output of 225 kW/306 hp.
With a view to the future Mercedes-Benz is also presenting two new
drive concepts in Frankfurt/Main, namely the E 200 NGT with a bivalent
petrol/natural gas power unit and a hybrid concept in which the powerful
V6 engine of the S-Class is combined with two electric motors.
