2012 Mercedes-Benz SLK Sets Safety Standards for Roadsters

The new SLK also features a unique combination of driver assistance systems which help to avoid accidents

The new SLK Roadster from Mercedes-Benz sets new standards in safety. The safety experts at Mercedes-Benz have long adopted the motto, the best or nothing, coined by Gottlieb Daimler. Mercedes is not content with just hitting safety ratings, they work to attain safety levels that not only meet but far exceed standars set by the world’s legislators. The most important measure of their work is not the laboratory or crash test facility, but actual, real-life accidents. They call the results of their work Real Life Safety, a concept which is based on research into thousands of accidents. Using this irrefutable evidence, the Mercedes-Benz engineers have developed or initiated most of the assistance systems which today effectively support drivers and have been adopted by many of the company’s competitors.

ATTENTION ASSIST and ADAPTIVE BRAKE as standard

The new SLK also features a unique combination of driver assistance systems which help to avoid accidents. These include the drowsiness detection system ATTENTION ASSIST, for example. Thanks to this system, the roadster develops a precise feeling for the level of attentiveness of the driver and can provide an early warning of overtiredness.

Also making up part of the standard equipment specification is the ADAPTIVE BRAKE. It comprises ABS, the acceleration skid control system ASR and also active yaw control (GMR). In addition, it features the following functions:

  • it supports the driver when moving off uphill, by preventing the vehicle from unintentionally rolling back;
  • it also keeps the vehicle stationary without having to keep the brakes applied continuously – for example when waiting at traffic lights
  • as soon as the driver abruptly steps off the accelerator, it brings the brake pads into light contact with the brake discs as a precautionary measure, so that the necessary braking pressure can be attained quicker in the possible event of emergency braking;
  • in wet conditions it applies light brake contact, without the driver even noticing, to dry the brake discs.

The ADAPTIVE BRAKE works in conjunction with the equally adaptive brake light. In emergency braking situations, it warns vehicles behind with flashing brake lights.

Emergency braking on detecting an acute risk of a front-end collision

Available as optional extras are the DISTRONIC PLUS proximity control as well as the PRE-SAFE® Brake, already tried and tested in other Mercedes-Benz models. Both systems work in conjunction and can initiate emergency braking automatically on detecting an acute risk of an accident.

In normal driving conditions, the radar-based DISTRONIC PLUS proximity control adjusts the distance to the vehicle in front automatically. If necessary, it can apply the brakes, even bringing the SLK Roadster to a stop, and accelerate it again. This takes some of the strain off the driver, particularly in bumper-to-bumper driving conditions. If the distance starts to narrow too quickly, the system gives the driver visual and audible warnings, thereby prompting the driver to take action, at which point he is also supported by Brake Assist PLUS (BAS PLUS).

If the systems detect the acute danger of a rear-end collision and the driver fails to respond to visual and acoustic warnings, the electronics activate the PRE-SAFE® Brake in preparation for autonomous braking. This happens in two stages:

  • Around 1.6 seconds before the calculated impact point the system decelerates the car with around 40 percent (approx. four m/s²) of the maximum braking power, gives the driver an additional, haptic warning of the impending impact and as a precaution activates the reversible PRE-SAFE® occupant protection system.
  • If the driver still fails to react, the PRE-SAFE® Brake activates the maximum braking power around 0.6 seconds before the now unavoidable collision – this emergency braking can greatly reduce the severity of the impact. The system therefore acts like an “electronic crumple zone”, offering the car occupants even greater protection.

The PRE-SAFE® Brake is active at speeds of between 30 and 200 km/h when moving vehicles are detected in front of the car. The system also reacts if the car approaches a stationary queue of traffic, providing its speed is below 70 km/h.

Safety and comfort

Those wishing to do so can extend the range of assistance systems in the new SLK even further with the addition of features enhancing both safety and comfort:

  • The Intelligent Light System provides five lighting functions (cornering light function, country mode, motorway mode, active light function and enhanced fog lamps), which are activated depending on the driving conditions
  • Speed Limit Assist is able to detect speed limit signs using a camera on the inside of the windscreen, and indicate the detected speed limit in the instrument cluster or central display.
  • The optional PARKTRONIC incl. Parking Guidance supports the driver when parking. Its ultrasonic sensors measure the length of parking spaces as the car drives past; the cockpit display then provides a schematic representation of the recommended parking manoeuvre.

Only available from Mercedes-Benz – the anticipatory occupant protection system PRE-SAFE®

An additional safety highlight available in the new SLK is the anticipatory occupant protection system PRE-SAFE®, a system developed by Mercedes-Benz which is unique throughout the world. If the system detects an acute risk of an accident, it reflexively activates precautionary protective measures for the vehicle occupants, so that the seat belts and airbags are able to fulfil their protective function to the full during an impact. Mercedes-Benz developed PRE-SAFE® on the basis of research into actual accidents, and is the only manufacturer in the world to offer such a system. This highly effective system, however, has so far not been taken into account when producing ratings.

In the new SLK, additional post-crash measures supplement the PRE-SAFE® system to enable prompt assistance after an accident has occurred: depending on the damage, the interior lighting can be switched on automatically, the side windows can be opened by 50 mm to provide better ventilation in the interior, and in vehicles with the Memory package the steering wheel can be moved upwards.

Taking into account all of the requirements of the rating institutes

In developing the new SLK, the requirements of Euro NCAP as well as all of the global consumer ratings have been taken into account. This has contributed to the development of the bodyshell structure of the vehicle, which follows established concepts and has been optimised in a number of detailed areas. These include, among other things, reinforced members, a new side impact structure and new fibre-reinforced roll-over bar.

In the event of an accident, up-front sensors and lateral satellite and roll-over sensors help the central control unit to predict the nature and severity of the accident. New, additional pressure sensors in the doors as well as acceleration sensors in the front bumper help in detecting an impact with a pedestrian.

New headbag and crash-responsive head restraints

The restraint systems with two-stage driver and front passenger airbags have also been enhanced. A new feature is the headbag, which provides generous lateral protection for the head impact area. An additional thorax airbag in the seat backrest protects the upper body in the event of a side impact. The seat belts, with belt buckle tensioners and speed-sensitive belt force limiters, serve to highlight the high safety standards of Mercedes-Benz.

Another new feature finding its way into the standard equipment of the forthcoming SLK comes in the form of the NECK-PRO crash-responsive head restraints, developed by Mercedes-Benz. They support the driver’s and front passenger’s head in the event of a rear impact and reduce the risk of whiplash. Also fitted as standard is automatic child seat recognition.

Protection for pedestrians

The new SLK Roadster uses the latest technology in the area of pedestrian protection too. A sensor system is able to register an impact with a pedestrian and can ensure that the bonnet is immediately raised by 85 mm. This creates additional space between the bonnet and the components in the engine compartment. This in turn results in comparatively lower acceleration values for the head of the pedestrian during the impact, thus reducing the overall risk of injury.

As a result, the new SLK provides its occupants not only with a superior level of safety in all areas – something which is unique in this segment – but also enhanced safety for other road users too.

New Generation SLK Roadster Design Journey

The design idiom accentuates the Mercedes SLK's lively, sporty presence, and is also sculptural

The designers have tailor-made an outfit for the new SLK which emphasises its classic roadster proportions and puts them in the spotlight to thrilling effect. Behind the long bonnet is a compact passenger compartment positioned far back, and a short tail end. The SLK will tempt potential customers with the key attributes that characterise all the classic roadsters from Mercedes-Benz, and that have also made many of them automotive icons.

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, sporty 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 characterise the essentially very sporty atmosphere.”

Striking front end

The first feature to catch the eye is an upright radiator grille that stands proud and confident in the wind, bearing the new face of the Mercedes-Benz brand. It facilitates the long and well-proportioned bonnet and with its rearward light-catching contours it already hints at the roadster’s dynamic qualities. The bonnet ends with two air intake grilles in front of the windscreen, each embellished with three louvres.

The wide radiator grille bears the Mercedes-Benz star in a prominent central position and displays a powerfully contoured fin, chromed at the front. The clearly defined headlamps complete the look for the new SLK’s face, and daytime running lamps with chrome surrounds (round lamps in the base version) in the bumper round off the front end. The “face” of the new SLK is reminiscent of the legendary 190 SL from the 1950s, which is regarded by many as being the original “SLK”. But it was certainly not just the past that the designers were focusing on; with the new SLK’s front end they also intentionally created a close visual link with the new Mercedes-Benz SLS AMG “gull-wing model” and the new CLS.

The amazing and measurable proof of the meticulously detailed work that has been carried out is that in spite of the more striking, steeper front and the larger frontal area, the Cd value has been cut to just 0.30 (preceding model 0.32).

Dramatic lines

The classic, timeless lines of the side aspect with its typical roadster proportions embodies the utmost aesthetic appeal with a visual assurance of sportiness and fun. The vario-roof spans the interior like a drawn bow. When opened it disappears into the boot, creating the typical roadster silhouette. From any angle and in any position it blends harmoniously into the overall design. A fillet conceals the boot joint, so that it does not disturb the side aspect as with similar roof designs. Neither are the lines disturbed by aerials in most equipment variants: in most cases they are integrated into the windscreen, rear window and parcel shelf.

The air outlet grilles with a chromed fin in the front wings are reminiscent of the famous Mercedes-Benz 300 SL Roadster from the 1950s. In the new SLK they form the elegant starting point for a feature line which extends right back to the muscular rear wings, and uses light and shadow to lend style and elegance to the side aspect.

This is emphasised 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 colour, these make a sporty and filigree impression. Their sophisticated aerodynamics also help to keep the side windows practically dirt-free, while ensuring a low level of wind noise.

Depending on the engine variant, the wheel arches house 16 or 17-inch light-alloy wheels, or 18-inch wheels with mixed-size tyres in conjunction with the sports suspension.

Muscular rear end

At the rear the eye is drawn to the integrated spoiler lip and wide tail light clusters. The roll-over bars feature double-skinned plastic claddings with a high-quality soft-look surface. As an optional extra these rear claddings can be of anodised aluminium.

For the first time, the tail lights with their pronounced horizontal emphasis are in all-LED technology. Their upper edge extends forward into the sides, harmoniously culminating in the feature line. A twin exhaust system with trapezoidal tailpipes rounds off the muscular impression created by the rear view.

High-grade materials and stylish sportiness

The new SLK is 31 millimetres longer and 33 millimetres wider than its predecessor. With the most compact dimensions in its class, the new SLK has an interior whose generous size is nonetheless exemplary. To achieve this, the designers have developed interior appointments which offer the driver and passenger outstanding perceived value, purist precision and a real feel-good ambience. The interior in the base colour black is characterised by sporty refinement, well thought-out ergonomics and high-quality, authentic materials which have been processed with painstaking attention to detail and skilled craftsmanship. Even in the base version, the centre console and other trim parts gleam in brushed aluminium. Wood can be selected as an option in high-gloss dark brown walnut or high-gloss black ash.

Echoing the exterior design, the black dashboard emphasises the horizontal lines and therefore width of the vehicle. On request it is available in a two-tone colour scheme and with a leather lining. Four round, galvanised air vents similar in form to those in the SLS are recessed into the dashboard, underlining the car’s membership of the Mercedes-Benz sports car family and at the same time deliberately creating associations with the dynamism of jet aviation.

Two large dial instruments – a speedometer and a rev counter – flank a display for the information generated by the online computer. The display menus can be conveniently accessed by the driver using the control buttons on the steering wheel, without taking his eyes off the road. The colour display for the communication and entertainment functions is housed in the centre of the dashboard, and can be easily read by both the driver and passenger. A comfortably shaped controller on the centre armrest ensures safe and easy operation.

On the top of the dashboard, also in the centre, sits a fine analogue clock (optional), subtly underlining the roadster’s stylish character.

An easily handled (diameter 375 millimetres) multifunction sports steering wheel with a flattened bottom section and a thick leather rim makes the high quality and sporty character of the new SLK a constant tactile experience. Metal trim on the spokes enhance the impression of both sportiness and refinement. Shift paddles to perform upshifts and downshifts in the automatic transmission are available as an option. The interior can be enhanced even further with a wood/leather steering wheel.

The sweeping lines of the upper dashboard section are continued into the door panels. The door centre panel is colour-coordinated with the interior. The door openers and seat adjustment switches are trimmed in aluminium or 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 a high level of comfort on long journeys. Maximum operating convenience and seating comfort is ensured by optional electric seat adjustment with a memory function and 4-way lumbar support.

In the base version the new SLK is equipped with black fabric seats. There is also a choice of:

  • embossed leather in black, sahara beige or crystal grey
  • nappa leather in black, bengal red or moccha/nut brow
  • Exclusive nappa leather – in this case the upper dashboard section and the doors are lined with black nappa leather

All leather and nappa leather seats are upholstered with leather which noticeably reduces heat build-up. The leather has a special coating which reflects the sun’s rays. Comparative measurements have shown that this leather reduces the temperature of the seats by more than ten degrees Celsius – 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.

Magical lighting

An ambient lighting system available as an option for the first time creates an impressive effect in the interior of the new SLK. It consists of discreet optical fibres and spots in SOLAR RED, which produce an extremely pleasant yet sporty lighting effect in the door panels, around the door pulls and on both sides of the centre 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 lighting unit in the overhead control panel has two interior lights and a centre console spotlight.

Clever stowage compartment concept

For a two-seater roadster, the new SLK has an exemplary variety of stowage facilities in the interests of versatility and day-to-day utility. The basis for this well conceived interior concept is a large glove compartment with a remarkable capacity of 6.4 litres. Useful features such as holders for a pen, credit cards and coins are integrated into the glove compartment lid.

There are three stowage compartments in the centre console – below the air conditioning controls (this can be replaced by an ashtray on request), next to the controller in front of the armrest (roller-top compartment, optionally a drinks holder) and under the armrest with a 12 V socket, USB interface and AUX connection (optionally a media interface for integration of e.g. an iPod and mobile phone connection). A net attached to the tunnel in the passenger footwell can be fitted with a flexible bottle-holder which can securely accommodate even 1.5-litre bottles.

Excellent climate

The new SLK is equipped with air conditioning as standard. The automatic climate control system THERMOTRONIC with separately adjustable interior temperatures for the driver and passenger is available on request.

An example of the detailed refinements: a windscreen demisting sensor in the stem of the rear-view mirror registers the glass temperature and interior humidity level of the new SLK. In dry weather, when no cooling is required but A/C is operating, the control system powers the compressor down but activates it as soon as it registers that the windscreen is misting up. This has two advantages:

  • The A/C function can remain active all the time, but the demand-controlled system saves energy.
  • As the air conditioning only demoisturises and cools as much air as is required to maintain the interior temperature, the air is never too dry and this benefits the physical comfort of the occupants.

2012 Mercedes-Benz SLK Options and Extras

Firmly embedded in the genes of the Mercedes SLK is exhilarating driving pleasure in any weather conditions

Now in its third edition, the all new Mercedes-Benz SLK raises the bar when it comes to driving pleasure. The roadster offers driver’s a quick and responsive engine inside a stylish yet comfortable open-top sports car. Mercedes managed to pack all these attributes into a great looking, environmentally conscious vehicle that is built to be driven on a day to day basis. Thus making it one of the top car designs out this year. The 2012 SLK350 goes on-sale in the U.S. in June 2011.

“The new SLK embodies the role of the trend-setter like no other car,” says Dr Dieter Zetsche, Chairman of the Board of Management of Daimler AG and CEO of Mercedes-Benz Cars. “I am convinced that with its passionate design, its high-quality interior and its modesty at the filling station, it will also continue to provide an enormous amount of fun on the road in future, consolidating its status as a cult roadster.”

Innovations are part of the successful history of the Mercedes-Benz SLK:

  • In 1996 the first generation caused a sensation with the vario-roof, which transformed the wide-open roadster into a coupé with a fixed roof at the touch of a button in just a few seconds;
  • The second generation placed the warm AIRSCARF around the neck and shoulders of the occupants as needed, ensuring pleasurable open-top motoring even in cooler temperatures;
  • For the very first time, the third generation offers a choice between three variants of the much-imitated vario-roof. One of these is celebrating its world premiere – the transparent panoramic vario-roof with MAGIC SKY CONTROL, which can be switched to light or dark. It therefore offers a choice of an open-top feeling even when the roof is closed, or provides shade in strong sunshine and prevents the interior from heating up. Alternatively the vario-roof is available in painted or glass versions.

The highlights of the new Mercedes-Benz SLK also include a striking and masculine sports car design, a sporty and refined interior with authentic, high-grade materials and a choice of three suspension variants – a standard suspension, a sports suspension or a suspension with automatically adjustable damping.

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. The original book of specifications already laid down that the design characteristics of the new roadster must not be one-sided, but must ensure top performance in all major disciplines. Mercedes-Benz engineers have rigorously translated this requirement into reality, and given the SLK attributes that guarantee the roadster a peak position in its segment in multiple respects. Among them are extremely compact dimensions combined with an extremely generous interior providing a feel-good atmosphere and numerous practical features. Naturally outstanding performance and sporty, agile handling are also major characteristics of the new SLK. Moreover, the new SLK is the most economical petrol model in its class, with three new, efficient and powerful direct-injection engines plus the ECO start/stop function, and 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 motoring. It combines its decidedly 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 a character, and everyone will want it.”

A look back at the success achieved by the preceding models. Since the first generation was launched, the SLK has won the enthusiasm of more than half a million customers.

2012 Mercedes-Benz SLK From Concept to Production

The complete development of the all new 2012 Mercedes-Benz SLK from concept, design to production

From the initial vision to the final production SLK model – watch the development and testing of the new 2012 Mercedes-Benz SLK-Class below.  Under the body of the new roadster a gigantic effort has been taken, intense engineering work, including several years of test runs.  Freezing cold, scorching heat and long-term stress tests – these are only three of the many hurdles Mercedes-Benz engineers had to overcome to bring the SLK Roadster into series production

Chicago Tuner Speedriven Looking For CNG Speed Records

The 2007 SL600 Mercedes-Benz roadster, after nearly a year of research and development, offers over 800 horsepower

A powerful and responsive, 5.5-liter twin-turbocharged V12 engine is not usually what comes to mind when you think of “green” cars, but – if Bernie Towns and the crew at Speedriven get their way – it soon may be.

Bernie Towns is an engineer at HighMount Exploration and Production – a natural-gas-focused energy company based out of Houston, Texas. “Clean” and “green” are everyday buzzwords in the energy-production industry, and Towns’ company Future Power Technology well be no exception, promoting research into new ways to push CNG into the mainstream. In addition to being well-versed in current green-energy trends, however, there is something about Bernie Towns that is different from the usual green-car advocates. “I admit it. I’m a horsepower addict,” Bernie says. “I love speed, I love power, and I love my Mercedes-Benz.”

The object of Towns’ current automotive affections is a 2007 SL600 Mercedes-Benz roadster, which – after nearly a year of research and development work by Chicago-based tuning firm Speedriven – now develops over 800 horsepower and over one-thousand pound-feet of torque from its biturbo V12. Good enough for 10-second quarter mile runs and a top speed well in excess of 200 mph.

Towns’ massively powerful Speedriven SL satisfied his need for speed, then, but Towns still felt that something was missing. “In the IT world, we literally spend hours of every day coming up with ways to do business in more efficient ways and (at HighMount) in more environmentally responsible ways,” explains Towns. “So there I am, sitting at lunch one day and the people are talking about natural gas cars, and it suddenly hits me: we should convert the SL to run on natural gas!”

“In a lot of circles, green is the new fast,” says Speedriven’s Jo Borras. “I think that’s true, and Bernie is certainly a believer. He’ll talk about CNG giving off 80% fewer harmful emissions than gasoline, and he has the resources to figure out flame-front speeds, burr temperatures, and other technical things we need on our end to properly tune for the gas and convert the car. He doesn’t just want to do a CNG Benz, though. Bernie wants to break records.”

“Audi has the current record, at 364.6 kilometers per hour that they set back in 2009. That’s just over 225 mph, which they did in a heavily tuned Audi S4 making about 700 hp,” explains Towns. “That wasn’t standing-mile speed or anything, that was all they could get out of that car. The Mercedes has a bigger engine to start with, and it’s a slipperier car – from the factory at least. By the time this is all said and done, we’ll be making at least another 100 horsepower over the record Audi, and Mercedes has already given us a better aero package to work with. 230 mph to 240 mph run on CNG powered fuel. That’s the goal, and why can’t we do it? We know that Oklahoma and Texas have an abundance of natural gas, and a ready infrastructure of responsibly operating and producing companies that employ thousands of Americans all the way from production to distribution at CNG-filling stations that are already in place and available to the public. This is exciting and this is fun and there is no better and more brilliant use of this type of clean power than in our vehicles.”

The next test of Bernie’s car is scheduled for the Texas Mile event in March, and the SL600 is already at Speedriven’s Chicago facility, getting fitted with a new turbocharger assembly designed to push the boundaries even farther. “The first step to put the ‘pedal to the metal’ on this project is for Speedriven to get the hardware to where it needs to be,” says Towns. “I think 200 in a standing mile, with 240 mph or so as the top speed. Once we’re happy with the hardware and with the programming and we’re getting the results we want on gas, then we’ll convert the car’s fuel system and scale the math appropriately for the CNG. That way we’re dealing with known quantities all the way through, introducing new variables one at a time. That’s how Speedriven wants to move forward and that’s how everyone on my end likes to do things as well. Methodical. Step by step.”

Bernie Towns and the crew at Speedriven are moving forward and gaining support with each passing week. Towns offers that the group has been in touch with Mercedes-Benz USA, and that the ANGA and NGV America are also getting “on board” with the project.

“We’re pretty excited. I’m pretty excited,” says an emotional Towns. “It’s not everyone who gets to go out and do something really exciting with emerging technology and clean energy and break speed records in the same car they drive home every day and still get to call that ‘work’. This is great!”

2012 Mercedes-Benz SLK Roadster Makes U.S. Debut

The new SLK is one of two car displays in the tent lobby of Mercedes-Benz Fashion Week and draws attention to its new design

The all new 2012 Mercedes-Benz SLK Roadster made its official U.S. Debut at New York’s Mercedes-Benz Fashion Week.  The scene at Mercedes-Benz Fashion Week heated up  as fans got their first glimpse of the red 2012 Mercedes-Benz SLK roadster.  Lincoln Center, the heart of the most anticipated runway shows with more than 80 designers presenting their Fall 2011 collections including Diane von Furstenberg, Carolina Herrera, Vera Wang, Michael Kors, Derek Lam, Tommy Hillfiger, Prabal Gurung, Nicole Miller, Charlotte Ronson, Tory Burch, and Betsey Johnson was the location for the roadster’s debut.

“With temperatures hovering in the mid 20s on the Upper West Side of Manhattan, it’s not a stretch to believe everyone is fantasizing about warmer weather,” said Lisa Holladay, manager of brand experience marketing for Mercedes-Benz USA. “The new SLK design takes the convertible experience to new heights and it will resonate with everyone watching the hottest styles on the runway while dreaming of their next adventure under balmy, sunny skies.”

The new SLK is one of two car displays in the tent lobby of Mercedes-Benz Fashion Week and draws attention to its new design through a photo op experience called “On the Scene.” Fashion fans can get up-close and personal with the SLK and have their picture taken right in the heart of the action of Mercedes-Benz Fashion Week. Each day fashion fans with the right look can strike a pose for the chance to end-up in the print edition of The Daily, which is handed out each day at Mercedes-Benz Fashion Week.

Beyond the SLK, the display is featuring design elements which bring to life the glitterati of Mercedes-Benz Fashion Week to create the ultimate scene. Life size illustrations of windblown beauties by Scandinavian fashion Illustrator Laura Laine and the sought after invisible shoes launching this February by Andreia Chaves, a Brazilian footwear designer.

The 2012 SLK is going on sale this summer. It combines sporty handling with stylish comfort that culminates into a striking car design that is suitable for everyday driving. A unique series of safety equipment makes the SLK a leader in its segment. Standard equipment on the vehicle includes, among other features, the ATTENTION ASSIST drowsiness detection system. Mercedes-Benz is also the world’s first automotive manufacturer to offer the panoramic vario-roof with MAGIC SKY CONTROL as an optional extra on the SLK. With this innovation, the transparent glass roof of the SLK can be darkened in a matter of seconds at the touch of a button.

2012 Mercedes-Benz SL-Class Spied Testing in Sweden

The upcoming 2012 Mercedes-Benz SL-Class was spied testing in Sweden this week with limited body coverings

The upcoming 2012 Mercedes-Benz SL-Class was spied testing in Sweden this week. Unlike past spy photos of the future roadster, the SL was spied without its traditional false body paneling.

Thanks to its limited coverings, the SL’s overall body shape is easily seen, with the next generation SL-Class appearing to note a wider base and a slightly taller bonnet than the current SL. Likely taking styling cues from the 2012 Mercedes CLS and SLS Supercar, the front of the SL will be the biggest change we’ll see.

GMotors spoke with the spy photographer that captured the new Mercedes, and he mentioned that the SL was testing together with an Aston Martin Vantage Roadster and a Jaguar XK, most likely for benchmarking purposes.

As for when we can expect the new roadster, the next-generation Mercedes SL will be launched later this year, with a world debut coming  at Frankfurt Motor Show.

To see more of the next-generation 2012 Mercedes SL-Class, hit the gallery below for a few pics, then head over to GMotors for the full spy photo gallery.  And a big thanks to Andrus for the tip.

Mercedes-Benz Super Bowl Ad Sneak Peak

Mercedes-Benz Super Bowl ad sneak peak reveals first looks at the 2012 Mercedes C63 AMG Coupe and SLS AMG Roadster

Earlier today we told you that Mercedes-Benz is going to be debuting a new 60-second ad in this year’s Super Bowl, and along with it will come the world debut of two new Mercedes models not yet seen by the public.  The total cost to debut the new models:  roughly $6 million, thanks to the Super Bowl’s impressive ad rate of $3 million per 30 seconds.  And while we could wait two days and simply watch to see the models make their $6 million Super Bowl debut, the truth is, I hate waiting, so I’ll do you one better.  I’ll give you a sneak peak of the models making their debut, not Sunday, but right now.

That’s right, ladies and gentelmen, I’m spoiling Mercedes’ $6-million dollar Super Bowl surprise, and you get to witness it firsthand.

So now, without further ado, the first view of the 2012 Mercedes C63 AMG Coupe and the first view of the 2012 Mercedes SLS AMG Roadster (along with a couple other already outed Mercedes models), all on display in the video and gallery below.

Oh, and before I go, let me go on the record saying this Super Bowl will be won by the Green Bay Packers.  Dom Capers is a genius; A-Rod’s the best quarterback in the league; and the Packers finally found a running game.  It’s a done deal.

Sorry for the diversion; hit the video and gallery below for the Mercedes Super Bowl ad featuring the first views of the 2012 Mercedes C63 AMG Coupe and the 2012 Mercedes SLS AMG Roadster

Mercedes-Benz History – 55 Years of Open Top Driving

Mercedes-Benz continues its roadster heritage with the 2012 SLK, a tradition that began with the Mercedes-Benz 190 SL

Orders for the new Mercedes-Benz SLK commenced on 17 January 2011. It will feature a new, exciting design, exceptionally high levels of comfort for a roadster, as well as exquisite technology and no shortage of open-air driving pleasure. As such, the agile sports car already looks set to continue a success story which started back in 1994 with a show car. Strictly speaking, however, the pedigree of the SLK stretches back even further – to the 190 SL, a vehicle which automotive enthusiasts were already dreaming about in 1955 as the economic upturn was starting in the Federal Republic of Germany.

When the SLK appeared as a series-produced car in 1996, it not only caused a stir on the road but also established a new market segment which has since grown by leaps and bounds. With the steel vario-roof, which transforms the roadster into an all-weather coupé within a matter of seconds, the roadster has been and still is the role model for many open-top cars. The success of the SLK has exceeded all expectations: to date, well over half a million owners have been delighted with their purchase of an SLK roadster.

The 190 SL – a new star in the automotive firmament in 1955

With the SLK, Mercedes-Benz continued its roadster tradition which stretches back a long way. Its direct ancestor is considered to be the 190 SL, which owes its existence primarily to the perseverance of Maximilian Edwin Hoffman. The enterprising American with Austrian roots was importing European cars into the USA as early as 1946, and in doing so demonstrated infallible instinct and tremendous flair. In 1953 he urged the executive boards of Daimler-Benz to build another affordable sports car, in addition to the 300 SL, for the American market. As an elegant sports car from a well-known company featuring an exciting design at a low price, the 190 SL was designed to charm the Americans.

After a development period of just five months, on 6 February 1954 the 190 SL celebrated its world premiere in New York, alongside the legendary 300 SL “gullwing”. Unlike the 300 SL, the 190 SL was not designed as a purebred sports car but rather as a sporty, elegant two-seater touring and utility vehicle. Its chassis was the shortened frame floor assembly from the Mercedes-Benz 180 (W 120), combined with the single-joint swing axle with lowered centre of rotation, as used in the 220 (W 180). The front-wheel suspension, including subframe design, came from the 180 model. The 190 SL was driven by a newly developed four-cylinder engine with a displacement of 1.9 litres, overhead camshaft and producing 105 hp. Depending on conditions, it could therefore reach a speed significantly over 170 km/h and accelerated from 0 to 100 km/h in 14 seconds.Series production started in May 1955.

The 190 SL was available as a roadster with soft top as well as a coupé with removable hard top, with or without a soft top as an option. A broad range of prominent social figures chose this elegant sports car to complement their image, including Grace Kelly and Frank Sinatra, who drove a 190 SL in the film “Ten Thousand Bedrooms”.

The Mercedes-Benz 190 SL was built up until 1963. The clearest indication of just how much loved and successful the 190 SL was is demonstrated by the production figures: between May 1955 and February 1963, no less than 25,881 cars left the assembly lines in Sindelfingen – far in excess of the initial aspirations.

Two studies for the new type of roadster

Against this historical backdrop, it seemed only logical some decades later to revisit these considerations: would it not perhaps be appropriate for the SL-Class Mercedes-Benz models, now firmly established in their own right, to be joined by a younger brother? After all, Mercedes-Benz had launched an entirely new product initiative, to which a compact roadster could lend fresh emphasis by drawing attention to the sporting heart of the Mercedes-Benz brand.

An appropriate acronym for this newcomer was swiftly coined: SLK. In German, these three letters stand for the car’s characteristic properties – sporty, lightweight and short – and, given the great sporting successes of Mercedes-Benz back in the 1920s and 1930s, they have an almost mystical resonance.

In Turin in April 1994, roadster enthusiasts were able to gain a first glimpse of how Mercedes-Benz believed a compact roadster should look. A brilliant silver showstopper with a distinct aura of spartan sportiness sent the trade professionals into raptures. Bruno Sacco, Head of Design for the brand at the time, made it clear what the company’s aim was: “We are exhibiting a forward-looking roadster study which delivers a unique synthesis of purist motoring pleasure with all the safety features for which Mercedes cars are renowned”.

To meet these requirements, some formal individuality was called for. The SLK study reflected this thanks to its compact dimensions and some evident highlights. Short overhangs at the front and rear, as well as a distinctive wedge shape, embodied the enjoyment to be had from a hands-on driving experience. And the two “power domes” on the bonnet, running parallel to the direction of travel, were acknowledgement of the originator of all SLs dating from the 1950s. The SLK study revealed a lot of gleaming metal. Only 20 percent of the interior was covered, and the high-tech cockpit was dominated by bold shapes and high-quality materials.

To find out just how seriously the people in charge at Mercedes-Benz were taking this SLK project in its earliest days, you need look no further than the Paris Motor Show held in September of the same year. Here the company unveiled its second study, this time with vario-roof and in the form of a customised version in blue, with blue-tone leather and a range of additional luxury accessories such as automatic transmission, air-conditioning system, power windows, a hi-fi sound system and much more besides. This enabled Mercedes-Benz to demonstrate convincingly the breadth of appeal and the potential inherent in a compact roadster.

The SLK sets the trend before going into series production

Then the automotive enthusiasts started to wait. Many viewed the SLK as a very auspicious prospect indeed. Mercedes-Benz had done the unexpected and had demonstrated that a small and relatively inexpensive roadster was capable of offering a great deal of motoring pleasure while still being an absolutely serious and down-to-earth car in terms of safety and quality. This meant that the roadster studies had already opened up a new market niche, making the SLK a trendsetter even before series production had begun.

By 1996 everything was in place: the series production version of the new SLK, designated internally as the R 170, was launched at the Turin Motor Show. Especially high levels of interest were shown in the fully-lowering steel vario-roof which substantively backed up the SLK’s claim to being a car for all weathers. Using an intelligent electro-hydraulic system, the entire roof folded down into the boot in just 25 seconds, leaving the owner free to roam under an open sky.

The SLK also fielded a convincing range of other qualities. Take safety for example: two fixed roll-over bars behind the seats protected occupants from injury if the car should overturn and, in conjunction with the exceptionally robust A-pillars, delivered a very high level of safety even when these Mercedes-Benz cars are driven with the top down.

Engines from 136 to 354 hp

The sporting talent of the SLK was unleashed by two engine variants: a 2-litre four-cylinder engine with a power rating of 100 kW (136 hp) and a supercharged 2.3 litre engine, also a four-cylinder unit, delivering 142 kW (193 hp). In early 2000, the two-litre engine was also fitted with a belt-driven supercharger, boosting power to the rear axle to a new level of 120 kW (163 hp). The choice of engines was broadened by the arrival of two six-cylinder models, the 160 kW (218 hp) unit for the SLK 320 and the 260 kW (354 hp) powerplant in the SLK 32 AMG.

The evolution of the SLK continues

In February 2000, Mercedes-Benz substantially upgraded the level of equipment for its roadster and incorporated innovations such as the Electronic Stability Program (ESP®), a six-speed manual transmission and SPEEDTRONIC in its standard equipment package. In visual terms, a new bumper and side skirts gave the car an even more dynamic appearance. All the attachments and door handles were painted to match the vehicle body to enable the whole car to present an image of a unified whole in terms of both colour and form. New taillights, stainless steel trim on the exhaust tailpipe and a painted radiator grille gave the SLK design an even more commanding identity.

Even more driving pleasure with the second generation SLK

In the spring of 2004, the second generation of the SLK (internal model series designation: R 171) was launched – offering more sportiness and dynamism, and even more driving pleasure. Thanks to powerful engines, a newly developed chassis, direct steering and a precise six-speed shift mechanism, the second generation of the SLK provided an even more responsive driving experience. As a world first, Mercedes-Benz introduced the AIRSCARF neck-level heating system. At the touch of a button, it generates warm air which is blown out of the head restraints. This now meant that drivers of the SLK were able to enjoy open-top driving and the open-air roadster experience all year round, even when outside temperatures dropped.

True to the principle of ongoing development, in 2008 the SLK underwent a comprehensive facelift. The most significant visual changes included redesigned front and rear sections and also a carefully modified interior with new instrument cluster and three-spoke sports steering wheel. The distinctive dynamic character of the two-seater was brought to the fore to particularly good effect in the SLK 350 courtesy of a high-revving V6 sports engine producing 224 kW (305 hp) along with an optional Direct-Steer system. In addition, despite their significantly increased performance, all of the engines were more economical in terms of fuel consumption and in turn therefore produced less CO2 emissions.

The new SLK sets standards once more

The new SLK, which was presented in January 2011 and designated internally as the R 172, will now also follow in these same footsteps. Thanks to new engines, among other things, the roadster will consume significantly less fuel, thus demonstrating that achieving pure driving pleasure while maintaining a clear conscience when it comes to the environment do not necessarily have to be conflicting principles. The new SLK combines nimble-footed sportiness with stylish comfort, a striking sports car design with absolute suitability for everyday use, and top-of-the-range performance with exemplary ecology. In addition, a unique series of safety equipment enables the SLK to assume the role of benchmark in this segment. Standard equipment on the vehicle will include, among other features, the ATTENTION ASSIST drowsiness detection system. Mercedes-Benz will also be the world’s first automotive manufacturer to offer the panoramic vario-roof with MAGIC SKY CONTROL as an optional extra. With this innovation, the transparent glass roof can be darkened in a matter of seconds at the touch of a button. Thanks to such a rich array of technical innovations, the SLK will once more set the standard in its class.

2012 Mercedes-Benz SLK-Class Officially Revealed

For the first time Mercedes-Benz is offering a choice of three variants of the lightweight construction vario-roof for the new SLK

The all-new SLK-Class, one of the most exciting and successful sports cars ever built, is entering its third generation. The 2012MY roadster takes driving pleasure and open-air enjoyment to the next level by blending nimble handling with stylish comfort, striking sports-car design, everyday drivability, top performance and exemplary efficiency. In addition, the 2012 SLK-Class is proud to present the world premiere of the panorama vario-roof with MAGIC SKY CONTROL, which switches between light and dark transparency at the touch of a button. Exemplary efficiency and athletic flair come courtesy of powerful new 4 and 6-cylinder engines With superb levels of performance, they are more fuel efficient than their predecessors and with unique new safety equipment the 2012 SLK-Class sets the new standard in this segment. With its wealth of technical innovations, the SLK is once again the benchmark in its class. The 2012 SLK-Class goes on-sale in the U.S. this summer.

“The new SLK embodies the role of the trend-setter like no other car”, says Dr. Dieter Zetsche, Chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz Cars. “I am convinced that with its passionate design, its high-quality interior and its modesty at the fuel station it will continue to provide an enormous amount of fun on the road in future, too, consolidating its status as a cult roadster.”

Innovations are part of the successful history of the Mercedes-Benz SLK:

In 1996, the first generation caused a sensation with the vario-roof, which transformed the wide-open roadster into a fixed-roof coupe at the touch of a button in just a few seconds.

The second generation placed the warm AIRSCARF around the neck and shoulders of the occupants as needed, ensuring open-top enjoyment even in cooler temperatures.

Now the third generation presents a unique highlight – the world premiere of the panorama vario-roof with MAGIC SKY CONTROL, which can be quickly switched to light or dark transparency at the touch of a button.

The new Mercedes-Benz SLK unites premium comfort and high-quality equipment and appointments with an especially athletic flair. At the same time the new roadster is the most fuel efficient in its class matched with segment-leading safety. All-weather driving enjoyment – open or closed, during weekends or the daily commute – is firmly anchored in the SLK’s genes.

Timeless aesthetics embody hallmark sports-car sensuality

The designers have tailor-made a body for the new SLK that emphasizes its classic roadster proportions and puts them in the spotlight with a thrilling result. Behind the long hood is a compact passenger compartment and a short rear overhang. The SLK will tempt potential customers with these key attributes that characterize all the classic roadsters from Mercedes-Benz.

The first eye-catching feature is an upright radiator grille that stands proud and confident in the wind and 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 190 SL 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 model” and the new CLS.

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 sportiness and driving pleasure in store. 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 cannot get in the way, 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 boast all-LED technology – also appears to flow into the feature line.

Interior with style and pure good looks

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 pure precision. The interior is characterized by stylish sportiness and genuine high-quality materials which have been processed 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 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.

The SLK’s generous round dials are astride a display for the onboard computer. The color display for the communications and entertainment functions is housed in the center of the dashboard, and is easily read by both the driver and passenger.

Other high-quality pieces of equipment include a multifunction sports steering wheel with a flattened bottom section and a thick leather crown, plus available sun-reflecting leather that noticeably reduces seat temperature, ambient lighting

Unique equipment: MAGIC SKY CONTROL

For the first time Mercedes-Benz is offering a choice of three variants of the lightweight-construction vario-roof for the new SLK: in just a few seconds this feature transforms the roadster into a coupe with a “fixed” roof at the touch of a button – and vice versa:

  • The standard version is a roof painted in the vehicle color.
  • Optionally available is a panorama vario-roof with dark-tinted glass.
  • The third option is a world premiere – the panorama vario-roof with MAGIC SKY CONTROL. This glass roof switches to light or dark at the press of a button. In light mode it is virtually transparent, offering an open-air experience even in cold weather. In its dark state the roof provides welcome shade and prevents the interior from heating up from
  • the sun’s rays. In other words: a comfortable atmosphere at the touch of a button.

Innovative AIRGUIDE wind-stop system

A comfortable alternative to the conventional wind-stop is a new pivoting wind-stop for the 2012 SLK, invented by Mercedes-Benz aerodynamics engineers. It consists of pivoting transparent plastic layers attached to the back of the roll bars. The driver or passenger can swing them to the center of the vehicle in an instant, thus taming turbulent air flow.

Spirit and efficiency

There will be two models of the 2012 SLK available in its first year, both powered by direct-injection engines. The completely redesigned V6 engine in the SLK350 develops 302 hp from its 3498 cubic-centimeter displacement, using this power to accelerate in 5.4 (est.) seconds from 0 to 60 mph (top speed 155 mph). Its fuel Later on in the model year, the SLK250 goes on-sale with a four-cylinder engine developing 201 hp from a displacement of 1796 cubic centimeters.

The SLK250 is equipped as standard with a 6-speed manual transmission and consumes an estimated 27 mpg (combined). From a standstill it reaches 60 mph in 6.5 seconds, and it has a top speed of 155 mph.

Suspension for the closest relationship with the road

A sports suspension with firmer springs and dampers ensures a sporty driving experience. Additionally the Direct-Steer system offers more handling and agility while also reducing the amount of physical effort required when parking.

During spirited driving, the Torque Vectoring Brakes produce a defined rotational movement about the vertical axis of the vehicle in fractions of a second through selective brake actuation at the rear inside wheel. This results in the SLK stabilizing without any compromises, and it steers into a bend precisely and under full control.

Clever use of materials and high levels of safety

The new SLK’s bodyshell has been further refined, with the hood and fenders now made of aluminum.

The 2012 Mercedes-Benz SLK also sets new benchmarks in terms of safety. The third generation of this icon will make use of a whole host of the latest assistance systems to support the driver, including the drowsiness detection system ATTENTION ASSIST, developed by Mercedes-Benz and fitted as standard equipment. Available through special order is DISTRONIC PLUS with PRE-SAFE¨ Brake, which can autonomously apply the brakes in the event of an impending safety requirements.

Optionally available is the Lighting Package that not only provides headlamp cleaning but cornering and active light functions.

The 2012 SLK-Class makes its U.S. showroom debut in summer 2011.

Mercedes-Benz SLS AMG Roadster Spied With Minimal Camouflage

The most recent spy photos of the future SLS AMG Roadster were captured on a ferry headed to Germany from Sweden

The most recent spy photos of the future SLS AMG Roadster were captured on the Stena Line Ferry headed to Germany from Sweden.

The photos who two SLS AMG Roadster soft-top prototypes alongside other Mercedes-Benz prototypes including the Mercedes-Benz ML-Class and a Mercedes-Benz SLS AMG Coupe. In addition to the Mercedes prototypes is an Audi R8 Spyder, possibly for engineers and designers to run comparisons against.

Monday we brought you news of the SLS AMG Roadster’s debut in Frankfurt where we will see the car without the gullwing doors and instead with its retractable roof. The SLS Roadster will feature AMG’s 6.3 liter (6,208cc) V8 with an output of 420 kW (571 PS / 563 hp) and 650 Nm (479 lb-ft) of torque. That makes for a 0-100 km/h sprint time of just 4.0 seconds and a top speed of 309 km/h (192 mph).

Mercedes-Benz SLS AMG Roadster Spied With Its Top Down

The 2011 Mercedes-Benz SLS AMG Roadster is spied testing with minimal camouflage and its top down

Although we still have some time to wait before the forthcoming Mercedes SLS AMG Roadster makes its official debut, new spy photos have emerged showing the model nearly undisguised, with its top down.  When it premiers, notable changes will include an electronic soft top; the addition of the AIRCAP and AIRSCARF technology that first debuted in the E-Class Cabriolet; and of course, traditional doors (as opposed to the current SLS’s Gullwing doors).

We’ll keep you posted as new details of the Mercedes SLS AMG Roadster are revealed; in the meantime, check out more SLS Roadster pics in the gallery below.  Thanks to Markus Jordan for the tip.

Mercedes-Benz SL65 AMG Black Series Tuned by MKB

Swabian engineers of the technology tuning company MKB add 345 hp to the Mercedes-Benz SL 65 Black Series

The highest commitment of MKB´s high performance engineering. Mercedes tuner MKB offers for the most powerful AMG supercar another 345 horsepower. The standard 670 hp are turned into 1,015 hp by the Swabian engineers of the technology tuning company MKB. The engine´s torque is limited to 1.300 Nm.

Before any lucky owner can turn the key of his SL 65 Black Series with the MKB P 1000 power train the car has to undergo an enormous engine conversion.

The new engine conversion for the most powerful AMG engine demanded the long term experience of the whole engineering team at MKB. The engineer’s basis is well known. Many AMG 65 owners trust MKB performance tuning and so they reach regularly speeds with their luxury coupes and luxury sedans on the Autobahn, speeds at which modern jet fighters had retracted their landing gear already.

The club sports AMG SL 65 Black Series plays a new role in the AMG product range but it must not step out of the classic power performance line at MKB. “Our main goal with the new engine MKB P 1000 isn´t a new one. We simply want to give back the top speed performance to this SL with its high downforceaerosetting. It should be v-max capable just like our other top speed efficient cars. And for this we need more than 800 engine horsepower,” points out MKB CEO Panagiotis Avramidis. But even 900 hp are not enough when you are holding the technological key for over 1.000 hp.

In fact the idea behind the SL Black Series is a whole new concept at AMG. The new high performance in both longitudinal and lateral acceleration showed a new principle. A principle that reduces the v-max for a better race track experience. But at MKB the typical AMG club sports pilot is well known so one thing is clear to the MKB engineers: Especially the longitudinal acceleration must not stop to soon and the most merciless push out of any corner reduces the lap time most easily.

So the MKB engine modification is in its depths is absolute outstanding compared to any other tuned 12- cylinder AMG engine. If costs are neglect able then one can work on the power plant with a greater creativity – inside and outside. The MKB package for the AMG SL Black Series covers the whole drive train and offers the demanded reliability for high speed trials at Nardo or several hot laps on the Nürburgring in succession.

The engine conversion MKB P 1000. A new philosophy. The focus on turbo charging. For the Swabian enterprise MKB and most respected technology tuner for Mercedes and AMG cars the work on high performance power trains is business as usual. Decent exterior design, refinement in the interior but magnificent thrust under the bonnet adjusted brakes and wheels are the MKB key visual in the market.

But this MKB P 1000 marks MKB´s step into the future. Even the name shows it clearly. And in Swabian decency it underrates the performance slightly. The new MKB style is the adaption to the vehicle basis: the Mercedes performance product range will be based upon turbocharged engines in the near future. MKB demonstrates with the MKB P 1000 and its over 1.000 hp output the ultimate technology leadership in that business branch.

The 6.0 litre AMG V12 gets in the MKB P 1000 conversion a completely new engine periphery – this means air intakes, turbo charger systems, cooling systems are the visible means. Inside MKB works as consequent too. Apart from MKB camshafts the power ECU has the important job to control the flowing gases in a way that maximum power output, drivability and sustainability will be combined on a high level. The engine pushes significantly forward from 1.500 rpm onwards. Anything like a turbo lag is unknown. The automatic gearbox is converted too to meet the increased engine torque.

Additionally MKB offers MBK LSD rear axles with different ratios to reach different end speeds.

The roll-out was in direct competition

MKB technicians demonstrated their full confidence as they made the first roll out at Hockenheim during the international drag race. In front of 8.000 spectators and an astonished announcer the AMG Black series with its MKB P 1000 won his two shoot outs versus specialized drag racing US muscle cars. “To race the ¼ mile was new to us,” tells Panagiotis Avramidis, “and this car had a final drive good for a theoretical 370 km/h. So the car runs only in the first two gears on the drag strip. And as we told the professional competitors that we must use the normal high street tire pressure for safety reasons we have been laughed at. But in the end it turned out it was not so bad for us.”

The first presented Version will use the final drive ratio for 370 km/h at 5.700 rpm. The MKB v-max is not measured yet. The testing at Nardo or Papenburg oval course will be held soon. The car should be fun to drive not only on the motorway so the engine kept its place low above the front axle. The standard room in the engine compartment of the SL and other Mercedes cars were kept in mind when developing the turbo charging banks and the air intake ducts. The original looks of the car – even when the drive train is massively converted – means a lot to the typical MKB customer.

Unchanged at the exterior but with a performance far beyond of most super cars and still with the typical Mercedes comfort to reach any High-speed Event without bruises or a stiff neck. With this sentence one can describe the result after a MKB P 1000 conversion of any AMG SL Black Series best. All in all the MKB P 1000 is spot on with his basis in regards of everyday use but it speeds ahead easily if necessary. MKB offers this conversion as a custom hand built car in the MKB workshop. There is no production number limit for the engine. After the launch with the AMG SL Black Series all other AMG 65 cars can reach over 1.000 hp at the real wheels. The total cost for the engine tuning is 116.800.- EURO in Germany including 19 % VAT. As this tuning can be only done at MKB and takes a lot of efforts the conversion time will take up to 3 month.

2012 Mercedes-Benz SL-Class Spy Photos and Video

The next-generation 2012 Mercedes-Benz SL-Class has been spied doing hot weather testing in Death Valley, California

The next-generation 2012 Mercedes-Benz SL-Class has been spied doing hot weather testing in Death Valley, California where photographers managed to get shots of interior and exterior as well as a video.

In terms of design, the next SL-Class looks have a taller bonnet, wider stance and a shorter rear overhang than the current Mercedes-Benz SL-Class. Overall proportions don’t look as if they will change much.

Retro styling cues can be seen from the first interior photos, but we will reserve judgement until we see more.

Under the skin, a lot of components will be shared with the SLS AMG supercar, drivetrains, suspension and very likely the 7-speed dual-clutch gearbox.

Engine line-up will include both V6 and V8 gas units, and a hybrid version is likely to be part of the range. As always, we will keep you posted as more photos and information comes in.

Mercedes-Benz SLM Future Speculation Detailed by Automobile

Automobile reports on the possibility of a new Mercedes SLM model range to compete with the Audi R8

If you’re wondering what the future holds for the high end of the Mercedes-Benz model range, Automobile magazine is reporting on the possibility of a new line of vehicles internally designated as the “SLM”.  Falling about $20,000 below the price point of the new SLS AMG ($189,000), the models are said to be true mid-engine designs, thus allowing Mercedes to directly compete with the Audi R8 and the upcoming production version of the BMW Vision EfficientDynamics coupe.  Design wise, the models will not resemble the current Gullwing, but they will likely use a modified version of the  SLS AMG’s aluminum spaceframe.

As for body types, Automobile speculates there may be as many as three versions of the SLM:  a coupe, a roadster and a hatchback.  On the coupe, the publication suggests a coupe with “heron-wing” doors (they swing out and then pivot up at a 45-degree angle) will be the likely starting point, whereas the roadster will likely be more of a speedster design (featuring a cut-down windshield and manually operated cloth top).  As for power, look for a 350-hp 3.5-liter twin-turbo V6 paired with two electric motors positioned in front of the driver to supply thrust, while the front axle, battery technology, and the electronics platform will likely be based on those found in the upcoming 2012 Mercedes SLS E-Cell.

At this point, this is all purely speculation.  If indeed the Mercedes SLM does come to fruition, it likely won’t be until 2015, and there’s a whole lot that can change between now and then.  If we hear anything new, we’ll let you know, but in the meantime, you can read Automobile’s complete predictions for a Mercedes SLM and take from it what you will.

2013 Mercedes-Benz SL-Class Spy Photos Emerge

New spy photos of the 2013 Mercedes SL-Class give a new glimpse of what to expect from the next-generation roadster

Yet another round of spy photos have emerged giving us a glimpse of what’s coming in the next iteration of the Mercedes SL-Class.  It’s still too early to discern much of the new SL’s styling thanks to extensive use of false body paneling, but some areas to take note of include a more upright front fascia with single louvre grille, the general headlight shape and the LED running lights.  In the back, a tail light shape is visible, but due to the heavy amount of plastic and camouflage there’s no way to discern how closely the finished product will resemble the shape we’re seeing now.  You know the drill – stay tuned and we’ll keep you updated as we get any new details of the 2013 Mercedes SL.  In the meantime, check out more 2013 SL pics in the gallery below, then head over to Car Advice for the full story.

New 2011 Mercedes-Benz SLK Roadster Spy Photos

A new series of 2011 Mercedes-Benz SLK spy photos have emerged that depict the new roadster traveling on the outskirts of Paris

A new series of next-generation Mercedes SLK spy photos have emerged that depict the new roadster traveling on the outskirts of Paris.  Unfortunately, false paneling hides much of the model’s design, revealing even less of the model’s design than we’ve seen in the past.  Nevertheless, we thought the photos would serve as a good reminder the next SLK is right around the corner.  Look for the 2011 Mercedes SLK-Class to make its debut as early as September at the Paris Auto Show. We’ll keep you posted as new details regarding the 2011 SLK are revealed; in the meantime, check out the lastest SLK spy photos in the gallery below.  Thanks to Carscoop for the pics.
