Stuttgart – The Mercedes-Benz SLK-Class Roadsters
have long captured the hearts of sports car enthusiasts. Incorporating around
650 newly developed parts, the SLK models of 2008 are even more dynamic and now
offer an even more emotionally charged driving experience. Key visual
enhancements include new-look front and rear sections as well as a meticulously
modified interior with a new instrument cluster and three-spoke sports steering
wheel. A fast-running V6 sports engine developing 224 kW and the availability of
a direct-steer system truly bring the bold, dynamic character of the two-seater
SLK 350 to life. Furthermore, all of the engines in the line-up are now far more
economical on fuel and, therefore, emit even less CO2, despite a substantial
increase in output in many cases. The new-generation SLK models will be
available in Europe from April 2008.
Since their first appearance in 1996, the compact SLK Roadsters have come to
symbolise Mercedes-Benz's dynamic brand image. Already a familiar sight on our
roads, the second-generation two-seater is to be further enhanced with the
implementation of a raft of measures in 2008, the aim being to further emphasise
the car's sporty character and continue the SLK-Class success story by
introducing new, dynamic, powerful elements. Some 310,000 first-generation
roadster models were sold between 1996 and 2004. And around 185,000 customers –
some 60,000 of them in Germany alone – have already purchased the
second-generation model since its launch in March 2004 (figures at year-end
2007). This means that total unit sales of the SLK Roadster are now approaching
the half-million mark.
The new-generation SLK displays new sporty highlights, further enhancing the
appeal of the successful two-seater with the trendsetting vario-roof that
transforms the car from a roadster into a weatherproof coupé in a matter of
seconds.
Distinctive character: even more pronounced arrow shape at the front
end and a diffuser-style rear end
The designers have given the already dynamic-looking two-seater cult model an
even sportier appearance. Eye-catching features include the new-look front
bumper with a modified air-dam arrangement and a more pronounced arrow shape. In
addition, the area around the Mercedes star has been restyled to render it even
more distinct in appearance. The designers have modified the rear end by
introducing a diffuser-style lower section that makes the Roadster appear more
powerful when viewed from behind – an effect that is enhanced considerably by
the trapezoidal exhaust tailpipes and the AMG-inspired darkened tail lights. The
now larger exterior mirrors feature LED indicators with a pronounced arrow
shape, while the range of light-alloy wheels has been revised.
High-quality cockpit and new three-spoke sports steering
wheel
Many of the interior details have also been redesigned and upgraded following
a careful process of material selection. Particular importance was attached to
optimising the interior so as to make it even more driver-oriented. Centrepieces
include a new three-spoke sports steering wheel with multifunction buttons and a
new instrument cluster with captivating dial surrounds.
New "gullwing red" leather appointments will be available – reminiscent of
the interior appointments in the legendary 300 SL gullwing model. Further new
additions include nappa leather appointments in "natural beige", which
complement the new "pale burr walnut" and "black ash grain" wood trims
perfectly.
Enhanced audio and telematics systems
Mercedes-Benz is installing the new NTG 2.5 audio and telematics generation
in the SLK for the first time. It is easier to operate and offers an even wider
range of useful functions. Standard features integrated in every radio include a
hands-free system with Bluetooth technology. Optionally available is a new media
interface in the glove compartment, allowing the full integration of mobile
audio devices such as an iPod, which can then be operated via the audio system's
user interface.
Together with the new telematics generation, Mercedes-Benz is also offering
the LINGUATRONIC voice-operated control system as an optional extra in the
SLK-Class for the first time.
Voluminous surround sound even when the roof is open
Passengers can enjoy a unique audio experience, regardless of whether the
vario-roof is open or closed, thanks to the optionally available harman kardon®
Logic7® sound system. Rich and voluminous surround sound makes for crystal-clear
listening pleasure, the like of which has never before been associated with a
roadster.
Fast-running sports engine: higher output and much lower fuel
consumption
The sporty credentials of the 2008 SLK generation are further enhanced by
three modified powerplants that consume less fuel and, therefore, emit less CO2.
The four-cylinder powerplant in the SLK 200 Kompressor and the six-cylinder
sports engine in the SLK 350 both offer substantially more power and torque.
Only the SLK 55 AMG retains its familiar engine – an eight-cylinder unit that
has lost none of its mesmerising performance capability and remains a unique
selling point in the SLK segment.
The Mercedes-Benz engineers paid special attention to the fast-running V6
sports engine that makes its debut in the new-generation SLK, totally altering
the six-cylinder unit's character by making sweeping changes to the mechanical
setup. Although the displacement remains the same at 3498 cc, the engine now
develops 224 kW at 6500 rpm – some 24 kW more than its predecessor. The peak
torque has also been boosted, by 10 Nm, and now stands at 360 Nm when the engine
is running at 4900 rpm.
This result was achieved by raising the engine speed limit to 6800 rpm; it
can even be increased to 7200 rpm for a brief period – oil temperature and other
engine parameters permitting. Other changes introduced include a higher
compression ratio, a new intake manifold and an extensively modified valve
train.
Further aspects which add to the emotionally charged appeal of the new engine
include deliberately powerful sports-engine acoustics with a strikingly emotive
sound design when decelerating. In combination with the 7G‑TRONIC automatic
transmission, the engine management system also blips the throttle automatically
during downshifts. As well as producing an extremely sporty sound, this
throttle-blipping function reduces load alteration effects.
Despite the higher output and high-calibre performance, the SLK 350 consumes
considerably less fuel. With the six-speed manual transmission on board,
combined fuel consumption is just 9.5 litres per 100 km, a remarkable reduction
of 1.1 litres per 100 km; if the 7G-TRONIC automatic transmission is fitted, the
sports powerplant returns a combined fuel consumption of just 9.2 litres per 100
km – an improvement of 0.9 litres compared to its predecessor. Lower fuel
consumption means that CO2 emissions are also reduced – by 23 g/km to 219 g/km
in the automatic version and by 28 g/km to 227 g/km in the manual version.
Three further engines to choose from
The engine line-up for the second generation of the successful SLK-Class is
being augmented by three further variants:
- The output of the four-cylinder supercharged engine has been boosted by
15 kW (to 135 kW), while its torque has been increased from 240 to 250 Nm.
Combined fuel consumption has been cut by 1.0 litres to 7.7 litres per 100 km
whilst CO2 emissions have been reduced by 27 g/km to 182 g/km.
- The SLK 280 has also been further improved with respect to fuel economy and,
therefore, CO2 emissions. Fuel consumption has been cut by 0.4 litres to 9.3
litres per 100 km (if an automatic transmission is fitted, the figure is 0.2
litres lower at 9.1 litres per 100 km), while CO2 emissions have been reduced by
11 g to 220 g/km (if an automatic transmission is fitted, the figure is 6 g
lower at 216 g/km).
- The SLK 55 AMG is still equipped with the familiar 5.5-litre V8 powerplant
developing 265 kW/360 hp and a peak torque of 510 Nm.
Standard equipment for the three new SLK models includes a precise-shifting
six-speed manual gearbox, while the SLK 55 AMG still comes with the 7G‑TRONIC
Sport seven-speed automatic transmission fitted as standard. For European
customers, optional extras include a five-speed automatic transmission. The
V6-powered SLK 280 and SLK 350 models can be specified with either the 7G-TRONIC
seven-speed automatic transmission or, alternatively, the 7G-TRONIC Sport with
shift paddles on the steering wheel.
New direct-steer system for outstanding agility and tangible driving
pleasure
A newly-developed direct steering system with variable steering assistance,
available as an optional extra (standard for the SLK 55 AMG), further highlights
the qualities of the SLK’s sporty chassis, combining agility and manoeuvrability
when driving on twisting roads, steering comfort when parking and assured
steering characteristics when travelling at high speed.
The direct-steer system is based on the previously installed speed-sensitive
power steering system and operates by purely mechanical means, meaning that
there is no need for elaborate actuators and complex sensors. At its heart is a
new rack with slick gearing, which ensures that the steering gear ratio changes
in tune with the steering angle. The ratio is indirect when the steering is in
or around the central position so as to ensure excellent straight-line stability
and, therefore, a high degree of confidence when travelling at high speed. At a
steering angle of just 5 degrees, the ratio starts to increase rapidly and the
steering feels much more direct. As a result, the number of steering wheel
revolutions from lock to lock is reduced by around 25 percent if the new direct
steering is fitted. This means that, even in city traffic, relatively little
steering wheel movement is required to correct the car's path. Fast sequences of
bends on rural roads can be negotiated almost intuitively with relatively small
steering movements – with assurance, precision and a healthy dose of driving
enjoyment.
Visually enhanced SLK 55 AMG
On a technical level, the SLK 55 AMG remains almost unchanged. The only
differences are a few visual enhancements. The front end of the AMG model now
features a new apron with a black-painted cross strut and side air outlets as
well as darkened headlamps.
The trendsetting SLK
As trendsetters and technology leaders, the SLK-Class Roadsters have long
enjoyed the image of a modern cult car. Even after extensive modifications, the
familiar outstanding qualities remain, such as the vario-roof that transforms
the roadster into a coupé in 22 seconds, not to mention the extensive
standard-equipment package, including head/thorax sidebags, adaptive front
airbags and two-stage belt-force limiters. A unique feature available on the is
the option of the clever AIRSCARF neck-level heating system, which allows
open-top driving pleasure all year round, even in winter.
Australian release Australian customers will get their
first taste of the new-generation Mercedes-Benz SLK-Class roadster range from
June. Australian models, pricing and specifications will be announced closer to
the date of release.
