Dr. Thomas Weber, Member of the Board of Management responsible for Group Research and Head of Development, Mercedes-Benz Cars: 'With the SLK we offer a wide range of technical alternatives to give customers a personal choice. Among them are a number of unique innovations. Moreover, the SLK is a prime example of how impressive performance, stylish driving comfort and high ecological standards can go hand in hand. In the 125-year history of the automobile, we have never experienced such major leaps in efficiency. Lower fuel consumption and even more driving pleasure - a formula we certainly translate into reality in the SLK.'
Outstanding on all fronts
The best or nothing - this motto is at the heart of the Mercedes-Benz philosophy, and also the guiding theme for the new SLK. From the start the roadster was designed to provide top performance in all areas, and Mercedes-Benz engineers have rigorously translated this requirement into reality giving the SLK attributes that provide the roadster with a peak position in its segment. Among them are extremely compact dimensions combined with a generous interior with numerous practical features. Outstanding performance and sporty, agile handling are also major characteristics of the new SLK. The new SLK is also the safest roadster with its unrivalled range of safety features.
Dr Joachim Schmidt, Head of Sales and Marketing at Mercedes-Benz Cars: 'Firmly embedded in the genes of the SLK is exhilarating driving pleasure in any weather conditions, open or closed, for recreation or day-to-day driving. It combines its sporty character with outstanding comfort and high-grade appointments. The new SLK also sets new standards among the compact roadsters where fuel economy and environmental compatibility are concerned. A wealth of outstanding attributes and technical innovations will once again make it the benchmark in its class - and undoubtedly also a success for our brand. The SLK is a roadster with character, and everyone will want it.'
Striking, athletic and stylish
The designers have tailor-made a body for the new SLK that emphasizes its classic roadster proportions. Behind the long hood is a compact passenger compartment and a short rear overhang - key attributes that characterize all the classic roadsters from Mercedes-Benz.
Professor Gorden Wagener, Head of Design at Mercedes-Benz Cars: 'The SLK continues the illustrious roadster tradition of Mercedes-Benz, and excitingly takes it into the future. The design idiom accentuates its lively, athletic presence, and is also sculptural. It expresses personality and sensuality. The same applies to the interior. High-grade materials, lovingly crafted details and a very exclusive finish characterize the essentially very sporty atmosphere.'
Striking front end
The first eye-catching feature is an upright radiator grille that bears the new Mercedes-Benz brand look. The grille emphasizes the long and well-proportioned hood, and with its light-catching contours it already hints at the roadster's dramatic qualities. The wide radiator grille bears the Mercedes-Benz star in a prominent central position and displays a powerfully contoured chromed fin at the front. The clearly defined headlamps complete the look of the new SLK's face and resemble that of the legendary 190SL from the 1950s, which is regarded by many as being the original 'SLK'. However, the designers did not just focus on the past; with the new SLK's front end they also intentionally created a close visual link with the new Mercedes-Benz SLS AMG 'gullwing' and the new CLS-Class.
The impressive result of this meticulously detailed work is that in spite of the more striking, steeper front and larger frontal area, the Cd value has been cut to just 0.30 - a brilliant achievement (the predecessor model's Cd value was 0.32).
The timeless, classic shape of the side profile with the classic roadster proportions embodies aesthetics of the highest caliber and is a visual cue to the vehicle's sportiness and driving pleasure. Fine details show the care that has been taken by the Mercedes-Benz designers. For example, a molding conceals the trunk joint, so that the side line doesn't interfere, as it usually does with similar roof designs. The ventilation grilles in the front fenders with a chromed fin are reminiscent of the famous Mercedes-Benz roadsters of the 1950s. In the new SLK, they form the perfect starting point for a feature line, which flows to the muscular rear fender, using light and shadow to add style and timeless aesthetics to the sides. Meanwhile, the upper edge of the wide headlamps - which for the first time feature LED technology - also appears to flow into the feature line.
This line is emphasized by the stemmed exterior mirrors, which are positioned on the beltline where they allow a better forward view to the side with their very narrow stems painted in the vehicle color. Their sophisticated aerodynamics also helps to keep the side windows practically dirt-free, while ensuring a low level of wind noise.
Muscular rear end
At the rear, the eye is drawn to the integrated spoiler lip and wide tail light clusters. For the first time, the tail lights with their pronounced horizontal design are in all-LED technology. Their upper edge extends forward into the sides, culminating in the feature line. A twin exhaust system with trapezoidal tailpipes rounds off the muscular impression.
Premium materials and stylish sportiness
Despite the most compact dimensions in its class, the 2012 SLK has generous interior dimensions. To achieve this, the designers have developed interior appointments that offer the driver and passenger the highest degree of quality and precision. The interior is characterized by stylish sportiness and genuine high-quality materials which have been manufactured with perfect precision and skilled craftsmanship. Standard brushed aluminum trim covers the center console; wood trim can be ordered as an option in high-gloss dark brown burl walnut. Four round, metallic air outlets integrated in the dashboard emphasize that this model truly belongs to the Mercedes-Benz sports car family, their shape being a nod to those in the SLS AMG.
Echoing the exterior design, the black dashboard emphasizes the horizontal lines and width of the vehicle. The SLK's generous round dials flank a display for the onboard computer. The color display for the communications and entertainment functions is housed in the center console and is easily read by both the driver and passenger.
An ergonomic multifunction sports steering wheel with a flattened bottom and thick leather rim makes the high quality and athletic character of the new SLK a constant tactile experience. Shift paddles and metal trim on the spokes add both sportiness and refinement. The interior can be enhanced even further with the Trim package which includes a wood/leather steering wheel and shift knob.
The sweeping lines of the upper dashboard section are continued into the door panels. The center panel of the door is color-coordinated with the interior and the door pulls and seat adjustment switches are trimmed in aluminum or optional wood.
Sporty yet comfortable seats
The sporty, ergonomic seats with adjustable crash-responsive NECK-PRO head restraints integrated into the backrests have high side bolsters for optimum lateral support and comfort on long journeys. Convenience and seating comfort is provided by electric seat adjustment with memory functions and 4-way lumbar support.
The Mercedes-Benz SLK350 offers a choice of Black, Sahara Beige or Ash sun-reflecting leather as well as Black and Bengal Red Premium sun-reflecting leather which noticeably reduces heat build-up. The leather has a special coating which reflects the sun's rays and measurements have shown that this reduces the temperature of the seats by more than 18 degrees Fahrenheit - a significant improvement in comfort when the car has been parked in the sun.
As in the previous model, the neck-level heating system AIRSCARF is available as an optional extra for the new SLK. This creates a flow of warm air around the neck and shoulder areas of the occupants from a vent in the front of each head restraint.
An ambient lighting system available for the first time as an option in the Sport Package creates an impressive effect in the interior of the new SLK. It consists of discreet optical fibers in SOLAR RED, which produce a pleasant yet dramatic lighting effect in the door panels, around the door pulls and on both sides of the center console. This mood-enhancing ambient lighting is activated when the doors are opened ('welcome home' effect), and its intensity can be individually varied by a dimmer.
The central interior lights are located in the overhead control panel and includes two interior lights and a center console spotlight. Additionally, a single LED is located in each A-pillar to provide extra interior illumination on entry and exit.
The operating principle is based on the physics of a plate condenser: if the glass structure is subjected to an electrical voltage, particles in the structure position themselves so that light is able to pass through the glass. If the voltage remains switched off, however, the particles position themselves randomly. This partially blocks the light, and the glass remains dark. The control unit and converter are integrated into the front section of the roof, and the switch is in the overhead control console.
UV and infrared light are also effectively blocked in transparent mode, while insulation increases even more significantly and noticeably in darkened mode, thereby helping to keep the temperature on interior parts such as armrests cooler by up to 18 degrees Fahrenheit compared with conventional tinted glass.
Measurements using a device called a star pyranometer in Death Valley, one of the world's hottest places, impressively demonstrated the effect. This device measures the intensity of exposure to sunlight. With an open roof, the thermal load from the sun in the heat of Death Valley reached 1000 to 1100 W per square meter. With the transparent glass roof it dropped to 200 W, and when the roof was switched to darkened mode with MAGIC SKY CONTROL, it dropped to 40 to 50 W - one 20th of the original value and less than a 60 watt bulb.
Modern headlamp technology and LED daytime running lamps
The Mercedes-Benz SLK350 is equipped with horizontally arranged LED daytime running lights with four LEDs. The new SLK can be optionally equipped with the Lighting Package which provides active and cornering light functions.
The active headlamp includes intuitive headlamp range control which automatically adjusts the angle of the light beam to changes in the car's attitude - for example pitching movements when braking and accelerating - or to accommodate changes in vehicle loading.
The wide tail lights of the new SLK feature full LED lights technology for the first time. This not only ensures an unmistakable nighttime design, but also enables LEDs to shine with different intensities in specific areas of the tail light cluster, depending on their lighting function. LED technology has other advantages: compared to conventional bulbs they light up around 0.15 seconds faster, and also have a considerably longer operating life.
