Since the production started back in 2004, more than one million vehicles of the current A-Class model generation (W 169/BR 169) have come out the assembly line at the Mercedes-Benz plant in Rastatt. The final car of this series, an A 180 CDI in polar silver, has recently left the factory. The vehicle will arrive at a customer in France. "We are very proud of the success story of the A-Class we will continue to write with the next series. Preparations for the start of the new A-Class are already in full swing.", said Peter Wesp, head of the Mercedes-Benz plant in Rastatt.The new A-ClassIn March this year the new A-class celebrated the world premiere at the Geneva Motor Show. Up to 18 inches lower than the previous model, the new generation displays a sporty, confident character. As the world's first automobile manufacturer, Mercedes-Benz has completely integrated digital and phone communication and functionality in the telematics concept of the W 176 generation. The new petrol and diesel engines are now more fuel efficient and meet any power requirements. They can be combined with the new six-speed manual gearbox or with the optional automatic transmission with double clutch transmission 7G-DCT. The new A-Class is the first car in its segment to feature a standard radar-based collision warning system with ADAPTIVE BRAKE ASSIST, which decreases the chances of a collision. The first units will be delivered to clients beginning with September 2012.About the Mercedes-Benz plant in RastattThe Rastatt plant was officially inaugurated in 1992, with the E-Class being the first model to be assembled there until 1996. From 1997 onwards, the facility was established as a production site for the new A-Class. Prior to 2004, when the second generation came into force, around 1.1 million compact Mercedes-Benz premium models were sold to clients all over the world. Moreover, the current A-Class series appealed to more than one million customers and, in addition, beginning with 2005, the B-Class was also introduced in the production portfolio of the Rastatt factory. This niche vehicle, marketed as a compact sports tourer, became instantly popular, with total sales exceeding 700,000 units. Therefore, the Rastatt plant is unanimously recognized as a competence center for the construction of compact cars from Mercedes-Benz.Starting September 2011, the new B-Class (W 246) was introduced in the range. Currently, preparations are being made at Rastatt to welcome the new A-Class, which is celebrating the world premiere at the Geneva Motor Show in March 2012. The new generation of Mercedes-Benz premium compact cars further includes three more sporty, emotional models, including a coupe and an SUV. The five new models will be built in a comprehensive production network comprising the Rastatt plant and the new facility in Kecskemét, Hungary. Three of the five models will be assembled at Rastatt.Credits: Daimler AGCopyright © 2012, Mercedes-Benz-Blog. All rights reserved.
Design defines the personality of a car. Mercedes-Benz artists have always successfully delivered an impressive and unmistakable indentity to every car released by the German carmaker during the 125-year history. As ultimate automotive trendsetter, the Stuttgart-based constructor is now ushering a new era for the premium compact class with the introduction of the new A-Class. Being the most eagerly awaited Mercedes-Benz automobile of 2012, the youthful hatchback is the fruit of an intense design development featuring both new and organic elements and inspirational styling from key visual concepts such as the SLS AMG, F 800 Style and F 125!. Seeing the final result, it goes without saying the A-Class inherently boasts the most refined and progressive design in the segment.Why not have a look through the links posted below which talk about the comprehensive design development of the new A-Class?

The path leading from the first drawing to the model approval takes around three years. In this time a Mercedes goes through an endless series of work steps in the course of which the designers, so to say, grope their way little by little to the final vehicle. From previously competing drafts, the team produces the next generation of a Mercedes-Benz.1. Drawing/Rendering: At the beginning of the design process there is always a drawing – hand-sketched on a piece of paper, or on a screen. Ideas that had previously only existed in the designer's mind become visible.
2. Package: The basis for every design is the package, the sum of all the technical requirements. This is the basis upon which the sketches have to be implemented in such a way that proportions, dimensions and lines give a harmonious image.
3. 1:4 clay model: Not everything can be simulated on the computer, which is why the next step is to create a clay model of every variant of a new automobile. Only then can the designers decide whether their drafts create the desired effect in three dimensions, too. At the same time virtual models are always created on the computer.
4. Model selection: The final form of the new car is chosen from numerous variants, in order to be formally examined in a 1:1 scale. With the help of scanning and milling machines the first full-size "prototypes" are made.
5. 1:1 model: All the individual details of the new model are fashioned by hand. A deceptively real-looking model is created. All the characteristic features of the new car reveal themselves.
6. Interior sketches: First drawings and renderings are created for the design of the interior. This is when the different equipment lines are born, i.e. the interiors where the future driver has to feel at ease. The leit motif here: "Perfect aesthetics" – a design that feels committed to beauty.
7. Interior clay model: The best way for the designer to experience the development of the form is with a 1-in-1 clay model, built, so to say, from the inside out. All the details are modelled until an aesthetically top-quality spatial feeling is created. As a rule, three alternative interiors are built for a decision to be made.
8. Colour & trim / operating and display concept (control and display system): The material and colour options for the vehicle interior are determined. From hundreds of fabric and leather samples as well as a virtually endless colour spectrum the equipment variants for the future motor vehicle are determined. All the control and display elements are designed and developed to the optimum.
9. Interior data control model: All the materials and colours are tested for effect on sophisticated 1-in-1 interior models under "real-life conditions". Every material and every colour receives a code and is specified.
10. Final model: The exterior and the interior with all their details are brought together to make a model. A deceptively realistic representation is created. All the characteristic features of the new car reveal themselves. The exterior shape of the future Mercedes-Benz model becomes tangible.
11. Model approval: The final point of every design process is the model approval by the Board. If this is successful, there is nothing more to stop the production of the new Mercedes-Benz.Credits: Daimler AG

Integrated in the global Mercedes Design network, the designers at the Advanced Design Studio in Como find an inspiring environment for creative thoughts.Always a good address: in the Villa Salazar near the shore of Lake Como, Italian fashion designer Gianni Versace used to produce bowties and neckties, before Mercedes-Benz opened the Advanced Design Studio here in February 1998. With its contemporary ceiling paintings, long corridors and different terracotta and wooden floors, the villa, built around 1750, is exceptionally inspiring for the around 20 designers who work here. This also holds true for the region itself: the famous triangle between the cities of Como, Milan and Turin is a centre of fashion and the furniture industry. Traditional crafts are highly valued there – an ideal environment for the Advanced Design Studio.
With its sister studios in Carlsbad (California), Tokyo, Beijing and Sindelfingen, the Advanced Design Studio in Como not only exchanges ideas, but also creative people. Gorden Wagener, Head of Design at Mercedes-Benz, is responsible for all the Studios. Apart from the approximately 440 designers who take care of the series production vehicles, at the five Advanced Design Studios over 60 designers work on the concepts that have enabled the brand with the three-pointed star to look up to a quarter of a century ahead into the future.
A variety of inspirations flow into the concepts for the vehicle interior design – because this is what the Advanced Design Studio in Como has specialised in. Designers can allow their thoughts free rein without immediately having to think of series production. The latter is, of course, the final goal of the ideas and reflections. With the so-called "appreciation model" the designers first implement their ideal conceptions and then look for a way to translate these ideas to series production. This allows for a more consistent and higher-quality result than what would be obtained by upgrading the vehicle interior subsequently.
The tasks of the creative professionals in Como are numerous. They carry out normal research, develop drafts and build models – and always look beyond the horizon in order to develop the automobile interior of the future. A certain fine disregard for old conventional rules is desirable in order to find fresh approaches.
"We don't chase after fashion phenomena", says Gorden Wagener, Head of Design at Mercedes-Benz, "we detect long-term trends which raise the value of our brand over the decades. Ideas which fulfil the highest requirements in terms of technology, performance, comfort and safety." A designer therefore has to "live in the future" and think two to three vehicle generations ahead of their time.
One of the first visible and tangible results produced by the Advanced Design Studios in Como was the interior of the Mercedes-Benz F 400 Carving research vehicle (Tokyo 2001). In 2002 the Vision GST, a forerunner of the Mercedes-Benz R-Class, followed in Detroit; 2003 saw the debut of the F 500 Mind research vehicle (Tokyo). In 2005 saw the public appearance in Washington of the Mercedes-Benz bionic car, and the F 600 HYGENIUS in Tokyo. The Mercedes-Benz F 700 research vehicle presented in 2007 featured an interior design based on cork and Alcantara®. In 2011 Mercedes-Benz presented the research cars F125! and F800 Style as well as the Concept A-CLASS; all three featured interior appointments from Como. Many unusual details of the Concept A-CLASS take their cue from the realm of aviation. Diverse components were restructured: the instrument panel and the centre console, for instance, consist only of a complex brushed aluminium structure. The result is a transparent, light, bionic forming.Credits: Daimler AGCopyright © 2012, Mercedes-Benz-Blog. All rights reserved.
To create fascination and brand identity: that's the objective of the Mercedes-Benz design philosophy, oriented towards long-term effect rather than short-lived trends, it taps into a "gene pool" of brand-typical style elements in the sense of a living tradition. At the end of this process is the car as an individual space for living.For Mercedes-Benz, design is literally a trademark. Because for over 100 years, design has characterised the image of the brand with the three-pointed star and has made visible typical Mercedes brand values such as fascination, responsibility and perfection. Insofar, design has important tasks on two counts – and Mercedes design has fulfilled them for many years now very successfully: the car's lines fascinate not only because of the product itself, they also serve as a mirror of the philosophy and profile of the Stuttgart-based automotive brand. In other words: design makes brand values visible – and sets its mark on them.
Design should also awaken passion, passion for the automobile and the wish to possess a model. "Love at first sight" has long been a slogan with a great reality content in the automotive trade. After arousing love at first sight, one of the main tasks of the designers is to create a lasting relationship and maintain the love affair over many years. The psychological arc goes from acquaint to recognise to brand awareness. It is not only a question of creating shapely, functional individual products, but of generating brand identity at the same time.
Identity and continuity
However, in order to build up and care adequately for such a successful brand image, long-term strategies and conceptual continuity are essential. New Mercedes models must indeed formally create a bridge to the future, but at the same time their lines may not abandon their origin. This guarantees that every new Mercedes-Benz possesses a clearly recognisable identity and shows its pedigree at the first glance. Although every model displays unmistakeable analogies with its predecessors, it shows a clear formal further development and heralds a new design era.
Given that a product life span of around 20 years is quite realistic for Mercedes automobiles, the designers must not indulge in passing fancies. The high market value which Mercedes-Benz passenger cars retain even after many years on the road is due not least to the fact that a previous model of Mercedes-Benz does not automatically "look" old. Even when new models come out in a model series, they don't detract from their predecessors, which continue to be desirable, in particular because of the enduring appeal of their design.
A Mercedes-Benz is always recognisable as a Mercedes-Benz. Meticulously and with great care, Mercedes-Benz designers ensure that certain style features, while being further developed, are retained in their basic form. Designers then speak of the brand's "gene pool". This is what they tap into, to care for and protect the style of the brand.
A good example of this is the typical Mercedes radiator grille – a feature which has identified and rendered unmistakable the motor car with the three-pointed star for over 100 years. Over this long span of time the radiator grille has been repeatedly developed further in a formal sense. Both in its basic proportions and in its details the designers try to interpret this identifying feature anew, creating a fresh, modern image.
This principle also applies for the sporty counterpart, the so-called SL radiator, which was directly derived from racing in the 1950s and has since become a symbol not only for Mercedes sports cars, but also for the refined sportiness which finds its expression in many model series. In the same manner as the saloon radiator, this element is also constantly being newly interpreted in the formal sense.
Through this detail work, form language and brand image retain their vitality, remain innovative and dynamic, but at the same time unmistakeable.
And yet an all-too-strict interpretation of the striving for formal continuity entails the risk of running into a stylistic dead-end alley, where there is no room for individuality. There is no such formal monotony at Mercedes-Benz; on the contrary: every model – whether it is a luxury saloon, a coupé, a roadster or a compact-class car – presents itself as an independent "personality". The common, well-known basic patterns of the form language are combined with new style elements that at first appear surprising, yet in conjunction with familiar elements condition, ever anew, the perception of the Stuttgart-based automotive brand.
Trends and reality
Recognising and shaping trends are important tasks of the auto designers. They live in the present, but their realm of action is the future. This calls for a very sensitive perception for changes in customers' life habits, for people's new attitudes towards their daily life and for those tendencies concerning form and colour made evident in other sectors such as the furniture industry or the electronics sector, for example. Or for impulses coming from other cultures; this is why Mercedes designers do not only work in Germany, but in Italy, Japan, China and the USA as well. The automaker has set up Advanced Design Studios at all these locations, to act as a sort of seismograph and pick up stylistic trends on site and analyse them to process them creatively. A key issue here is the ability to intuitively grasp that which can attain formal timelessness, and to develop a sensitivity for important, sustainable tendencies in art, culture and society.
However, having a vision for the future and being able to sense new trends is not enough. Because behind the manifold, diffuse wealth of future ideas on offer there lies the question of which of the currents does a brand like Mercedes-Benz want to allow itself to be influenced by. For Mercedes-Benz it has always been decisive to be, not fashionable, but modern.
That's why what is important is to distinguish between short-lived tendencies and long-term developments and thus identify customers' authentic expectations for the future. Mercedes designers therefore do not need trend counselling but rather a well-founded prognosis and concrete answers to the questions as to how people will live tomorrow, how they will consume and – in particular – how to enthral and inspire future customers. The challenge consists in reflecting about possible future developments and to think further – beyond the reality that bears the seal of trends and fashion.
Passion and practicality
This aspect is probably the most important and interesting of those that determine the work of automotive designers. It is all about people, or, more specifically, about customers and their personality. Because driving a car today means a lot more than reaching your destination in safety and comfort. Today, more than ever, the emphasis is on making the journey itself an experience that is enjoyable because one feels at ease in one's car, and because the car goes well with one's lifestyle – and because it is also possible to express style very well by means of the car. More than ever, the sensory perception of a product therefore plays an exceptional role.
Experience and enjoyment
Keeping the fascination for what is beautiful alive over the years is also one of the most important tasks of the interior designers. Its importance for design work is increasing. The interior of a car is conceived as a space for living, one where a lot of time is spent. That is why a pleasant environment is playing an increasingly important role in the motor car, too.
There is no doubt about it: customers have become both more demanding and more discerning over the years in this respect. They not only want a wide choice of possible appointments from which to pick precisely that which suits their individual taste and personality. They now also set greater store by the use of high-quality materials and precision workmanship. These of course help convey, whilst also making more tangible, values such as aesthetics, comfort and quality as part of the overall visual impression.
The objective of the interior designers at Mercedes-Benz can be summed up in a few words: one gets into the car, closes the doors and immediately feels at home.
Form and function
But for all their love and attention to detail: automotive designers are not packaging artists. It is by no means their task to simply pack new technologies or new vehicle concepts into a handsome form – they contribute decisively towards initiating new ideas and help them on their way to series production, The entire Mercedes-Benz strategic product initiative documents just how closely product strategy, design and technology work together at the Stuttgart-based automotive brand.
Mercedes designers are integrated right from the start in the concept phase and in the development process of new models. That also means: design work is team work; the design studio of a large-series manufacturer is not a dream factory. In a team both designers and engineers have to be ready to make compromises in order to find viable solutions that meet all the requirements. This poses harder challenges for automotive designers than for their colleagues in other industrial sectors. The motor car is one of the few industrial products from which the customer expects not only a handsome exterior, but also a perfectly-designed interior as well. In addition to this, the car is a product made up from different individual areas. Many of these details are quite as complex as entire devices produced in other industrial sectors.
Function and aesthetics, technology and art: what at first sight sounds contradictory has to blend into a harmonious overall concept in a modern car. The objective has been attained if design work and the engineering arts complement each other on a sophisticated level. Thus, practicality and good design are not natural enemies. Technological leadership is an integral part of the brand philosophy and it is the task of design to make this mission visible, while setting trends in its own way.
Visions and emotions
This is what show cars, concept and research vehicles are also for. They are conceived and developed in order to impulse auto-visions, to test new vehicle concepts and technologies, to intensify the dialogue with customers and also to analyse the public's reaction to these auto-ideas. Mercedes-Benz also carries out such auto-studies in order to take a look at the future in respect of stylistic developments and to offer designers a possibility to develop and implement new form languages.
But whether a unique research vehicle or series-produced – a motor vehicle is always perceived with one's senses. No-one can evade its emotional effect. Long before one has any idea about the relevant technical facts or innovations, through its mere appearance – that is, through its design – it awakens desires. It is the responsibility of the designers to awaken and keep alive these emotions. The goal of their work is to create automobiles in the field of tension between technology and design, that are characterised both by technical and emotional intelligence.
The designers' work is a success if customers buy cars not only for purely rational reasons but also with their heart – and mind.

Mark Fetherston, A-Class designer: "The A-Class puts an end to boredom in this segment."Mark Fetherston (35) earned his graduate degree in Transport Design at Coventry University in 1999. Since then he has worked at Mercedes-Benz, most recently on the design of the SLS AMG super sports car.Mr Fetherston, did you have to overcome particularly great resistance in the company in order to implement series production of the expressive, emotional design of the new A-Class, which does break with some preconcepts towards the brand?
Fetherston: To be quite honest – at first I wouldn't have imagined that at Mercedes we would dare to build such a car. But the Board gave us wide-ranging freedom in respect of the design of the A-Class. Indeed, they even encouraged us to be more progressive.
If you are so clearly breaking new ground – what is it that makes this new A-Class a true Mercedes, then?
Fetherston: The sculptural quality of the A-Class's form is typically Mercedes. This traditionally distinguishes Mercedes-Benz from other brands. We made the A-Class sculpture in clay by hand – you can't do this on the computer. Look for instance at the muscular shape of the shoulder above the rear axle. The character lines, in particular on the vehicle sides lend this sculpture structure and terseness. The Dropping Line is an elegant link to the Mercedes heritage, the high side sill line provides dynamism. The A-Class is a clear statement of the dynamism of the Mercedes-Benz brand.
Most recently you designed the modern SLS AMG gullwing. What is more difficult to design – a supersports car or a compact-class Mercedes?
Fetherston: In terms of dynamics, a super sports car is easier to design – because its proportions are intrinsically dynamic. But that is precisely why the challenge of implementing the sporty dynamics of Mercedes-Benz in the compact class was such fun.
And apart from the SLS super sports car, what else served as inspiration in the first design phase?
Fetherston: Nature itself is a very important source of inspiration; take for instance the way the wind sculpts sand into sand dunes – magnificent. One can also observe beautiful shapes in winter landscapes. I love aircraft, too. One of the greatest designs of all times is the Concorde – sheer aerodynamics. And even though it may seem a bit like a cliché – when you see the A-Class from the front, you can be reminded of a wild cat, a lion or a cheetah. Aggressive and sleek.
We thought of another likeness when we saw the A-Class for the first time: in the compact-car segment, the new A-Class is like the face in the crowd...
Fetherston (laughs): Yes, no other car is so progressive in this vehicle class. The A-Class puts an end to boredom in this segment.

The starting point for the interior design was the interior sculpture "Mercedes-Benz Aesthetics No. 2" presented at the Detroit Motor Show in January 2011 and which directed attention to the new Mercedes-Benz design language in the vehicle interior, too. The first concrete implementation of this was shown in April 2011 with the "Concept A-CLASS" created in the Advanced Design Studio in the northern Italian city of Como."The inspiration from aircraft design is continued in the A-Class", explains designer Jan Kaul. "The instrument panel is clearly divided into an upper part inspired on a wing profile and a muscular lower section. This creates the impression that the upper section is supported by a muscle."
The process used for the production of the muscle allows diverse soft surface textures. It is thus possible to create different surface appearances with an attractive play of lights thanks to three-dimensional structures embedded in foil.
"The interior of the A-Class represents a big step forward in terms of quality – both in the materials used and in the consistency of the design" says Kaul. Both objectives have been achieved with the help of a specific design idiom and through the various combination options possible with the high-quality materials selected. All trim elements have been given an electroplated finish, resulting in real metal surfaces with "cool touch" effect. The work has been executed with considerable care and attention to detail, so that they appear to have been moulded in one piece.
The instrument panel incorporates five round vents. "Like brilliant jewels they underscore the superior quality of the vehicle interior", explains Kaul. The outer rings of the round vents have a high-quality electroplated finish. The airflow direction is governed by an insert that is reminiscent of an aircraft turbine and reveals a meticulous attention to detail. This too has an electroplated finish in silver-chrome. The free-standing display screen features a black piano-lacquer-look front panel and a flush-fitting silver frame.
The instrument cluster comprises two large round instruments, each with a small dial set within it. When at rest, the dial needles stand at 6 o'clock. The pointer inlays are in white, although with the sportier design and equipment lines such as Urban and AMG Sport they are in red. The dials on the sporty equipment lines and packages are coloured silver with a chequered flag effect. The 3-spoke steering wheel comes with 12 function buttons and an electroplated bezel.
The centre dome and console, as well as the positioning of the various elements such as the head unit, lower control panel, air conditioning operating unit, stowage compartments, rotary push-button and armrest, reflect the findings of the ergonomics experts at Mercedes-Benz.
An extensive range of seat coverings, in terms of material (e.g. leather, fabric, Artico/fabric), colour combination and also geometry, provides scope for a broad range of individualisation options.
Sports seats with integrated head restraints are available, for example, as an optional extra with all design and equipment lines. The sporty nature of the seats is emphasised by the opening between the upper edge of the seat backrest and the head restraint. On the back of the front seats this opening is edged with a frame in silver chrome and, in conjunction with the Light and Sight package, can also feature ambient lighting.
Designer Jan Kaul sums up: "If you were to take a seat in the A-Class with your eyes closed – you would never think, upon opening your eyes, that you were sitting in a compact-class vehicle."

The pulse of a new generation. The new Mercedes-Benz A-Class caused a furore. Its first presentation at the Geneva Motor Show made headlines: "A" for all perfectly done" (auto motor & sport), "A" as in "all different" (Focus), "Top-class, this "A" (Bild), "A" as in "all new" (Der Spiegel), "Muscular, low, sporty" (AutoBild). Before the new A-Class rolls on its way to European dealers in September 2012, Mercedes-Benz is to provide - in several instalments – insights into important development steps on its way to its market inauguration. This time the topic is design.Standing as much as 18 centimetres lower on the street than the preceding model, the new A-Class communicates design and dynamism at the very first glance. This radical form language, presented and enthusiastically acclaimed around the world with the Concept A-CLASS, was consistently implemented in the series production car. The appearance of the new A-Class reflects this new Mercedes-Benz design strategy. The result is what is known as a two-box design with a distinct character of its own, a sportily emotive exterior and an exceptionally high-quality feel to the interior.
"Translating the new dynamic style of Mercedes-Benz into the compact class was a challenge that was great fun to tackle", explains Gorden Wagener, Head of Design at Mercedes-Benz. "No other car in this segment is as progressive as the A-Class. Absolutely typical for Mercedes is the sculptural shape of the A-Class. The character lines, in particular on its sides, lend the A-Class structure and terseness. The new dynamic style is perceptible at first glance in the interior as well."
Defined edges and tautly drawn surfaces mark out the exterior design of the new A-Class. The constant interplay between concave and convex surfaces creates a characteristic play of light, particularly along the sides of the car, which contributes to its unique appearance.
Typical features of the long, sporty front are its pronounced V-shape, the separate headlamps, the radiator grille with central Mercedes star and double slats to either side of the star, as well as the additional air intakes on the sides. The "dropping line" apparent in the side profile dissipates towards the vehicle's front end. The design of the headlamps, together with the configuration of the light functions within them, is a key element of the design concept.
The light modules and LEDs behind the headlamp cover glass have been arranged in such a way as to create the characteristic "flare effect" for the daytime running lamps and indicators. The so-called "flare" is made up of the feature line within the headlamp, the LED modules for the daytime running lamps and the bulb sets for the indicators. This signature effect gives the car its energetic look and so helps to define a new, youthful face for Mercedes-Benz.
The perfect interplay of dynamic design and excellent aerodynamics is nowhere more apparent than in the roof, with its smooth surfaces and taut, arcing curve. The silhouette reveals smooth, flowing lines finishing in a flat edge. The roof spoiler, which conveniently hides all the aerials, provides an extra sporty touch and gives structure to the roof assembly. The beltline rises to the rear to form a pronounced wedge-shape. The side view is distinguished by sensuously moulded sculptural side panels and crisp lines. The front structural edge, above the wing, falls in what is known as a "dropping line" in a gentle arc towards the rear. The powerfully-shaped shoulder muscles above the rear axle serve to emphasise the car's coupé-like character. A further line sweeps up from just in front of the rear wheel arch, then gently fades away. All these lines give depth and dynamism to the car's profile. Dynamic side sill panels provide a final finishing touch towards the bottom of the car, enhancing the appearance of elegant light-footedness.
The broad emphasis of the tail end is revealed in an interplay of convex-concave surfaces and edges. The tail lights continue the line of the muscular shoulders back towards the rear, while their horizontal orientation emphasises the car's powerful breadth. The light functions are provided by fibre-optic cables and LED modules. Here, too, the interaction between design and aerodynamics is very clear: the surface finish of the tail lights is not only an interesting design feature, but also improves the airflow around the vehicle thanks to defined airflow break-away edges in the rear section.

The beating pulse of a new generation: the centrepiece of Mercedes-Benz's appearance at the Geneva Motor Show (8 to 18 March 2012) will be the world premiere of the new A-Class, the sporty Mercedes in the compact segment. Also totally new is the SL 63 AMG, offering high performance par excellence. The E 300 BlueTEC HYBRID – the world's most fuel-efficient model in the luxury segment – will be on show for the first time in Europe, as will the lightweight, athletic and luxurious SL-Class and the ML 63 AMG. The SLK 55 AMG will be appearing for the first time in Switzerland. The C-Class Sport offers a new dimension in sportiness, while the C 180 and E 220 CDI BlueEFFICIENCY Edition are shining beacons of efficiency. The CL "Grand Edition" stands for the ultimate in elegant luxury.
With the new A-Class, Mercedes-Benz is opening a new chapter in the compact segment: emphatically emotional in design, dynamic, with engines rated from 80 kW (109 hp) to 155 kW (211 hp), highly efficient with emission values as low as 99 g CO2/km. The A-Class is a clear statement on the dynamism of the Mercedes-Benz brand. At the same time, it also highlights the fact that safety is not a matter of price at Mercedes-Benz – with standard-fit features including the COLLISION PREVENTION ASSIST radar-based assistance system. The new A-Class (length/width/height: 4292/1780/1433 millimetres) will be making its way to European dealers in September 2012.
"A stands for 'attack': the A-Class is a clear statement on the new dynamism of the Mercedes-Benz brand," says Dr Dieter Zetsche, CEO of Daimler AG and Head of Mercedes-Benz Cars. "It is new down to the last detail. Such an opportunity to begin with a blank sheet is rare in the field of car development. Our engineers and designers have seized this opportunity in convincing style."
The design of the A-Class: emotional with a very sporty character
The design credentials and dynamism of the new A-Class are immediately apparent at first glance as it crouches up to 18 centimetres lower on the road than its predecessor. The design idiom presented with the "Concept A-CLASS" has been adopted wholeheartedly in the series production vehicle: with a new interpretation of the classic two-box design, the Mercedes designers have created an emotional exterior with a very sporty character. " Applying the new dynamic style of Mercedes-Benz to the compact class was a challenge that we thoroughly enjoyed"," relates Gorden Wagener, Head of Design at Mercedes-Benz. "The sculptural aspect of the A-Class design is typically Mercedes. The feature lines on the sides in particular lend the A-Class structure and a welcome edginess."
The aim in designing the interior was to complement the exterior's sporty appearance. The interior additionally derives a quality feel which is unique in the compact segment from the design idiom, the selection of high-quality materials and the available combinations of materials. And as with the Concept A-CLASS, a smartphone can be fully integrated into the control and display system. A dedicated app allows full use of the functions offered by the iPhone®, with other smartphones to follow in the future.
All trim surfaces feature an electroplated finish in "silver shadow", giving them a genuine metallic surface with "cool touch" effect. "This is just one example of the way in which the quality of the A-Class's interior is not defined by classic trim elements but by consistent design and by the specific materials used", explains Hartmut Sinkwitz, Head of Interior Design. "The motto we used when designing the interior was 'pure sportiness, newly interpreted'."
Sporty exclusivity: the Sport edition redefines dynamic performance
The performance specialists from AMG were involved for the first time at an early stage of the development process for the compact car. This involvement has spawned the model line's most dynamic version – the A-Class Sport Edition engineered by AMG, whose looks reveal a particularly close affinity to the Concept A-CLASS – by virtue of the new diamond grille, for example.
The drive: new engines for petrol and diesel fuel
A broad range of petrol and diesel engines covers all power requirements while defining a new benchmark in efficiency: for the first time ever, a Mercedes-Benz will emit only 99 g of CO2 per kilometre.
The new generation of petrol engines with a displacement of 1.6 and 2.0 litres covers an output spectrum ranging from 90 kW (115 hp) in the A 180 through 115 kW (156 hp) in the A 200 to 155 kW (211 hp) in the A 250. Features common to all these engines are the combination of direct injection with exhaust-gas turbocharging, an enhanced combustion process and extended stratification ranges for lean-burn operation by means of fast-acting injectors for multiple fuel injections and multiple ignition according to the prevailing requirements. The 1.6-litre engine features the world premiere of the innovative CAMTRONIC system. As a result of adjustment of the valve lift at the intake end the quantity of fresh gas is limited in the partial load range, reducing fuel consumption.
The diesel engines also boast extreme efficiency and environmental friendliness, thanks to state-of-the-art injection technology and turbocharging. The A 180 CDI kicks off at 80 kW (109 hp) and offers maximum torque of up to 250 Nm, while in the A 200 CDI the maximum power output stands at 100 kW (136 hp), accompanied by maximum torque of 300 Nm. The A 220 CDI has a displacement of 2.2 litres and generates 125 kW (170 hp) of power and 350 Nm of torque, enabling outstanding performance in the A-Class.
All engines of the new A-Class feature the ECO start/stop function as standard. The engines can be combined with the new six-speed manual transmission or optionally with the 7G-DCT dual clutch automatic transmission.
Other highlights: chassis and suspension, aerodynamics, safety
The chassis realises the dynamism which is promised by the design and the drive technology. The substantially lowered centre of gravity and the new four-link rear axe provide the basis for the effective transmission of power to the road and for the potential deployment of 4MATIC all-wheel drive. The customer has a choice of various chassis and suspension set-ups, including the optional sports suspension with Direct-Steer system. The electromechanical steering of the A-Class has been redesigned. The electric motor of the servo assistance system is now located in space-saving configuration directly on the steering gear as a high-precision dual pinion EPS system.
The perfect aerodynamics of the A-Class grant it a Cd value of 0.26 – a new benchmark in its class. The standard-fit roof spoiler concealing all the aerials on board the A-Class is also a contributory factor here.
The A-Class is the only car in its segment to feature a radar-based collision warning system with adaptive Brake Assist as standard, which lowers the risk of rear-end collisions. The COLLISION PREVENTION ASSIST system gives a visual and acoustic warning to alert a possibly distracted driver to identified obstacles, and prepares Brake Assist for the most precise possible braking response. This is initiated as soon as the driver emphatically operates the brake pedal.
The PRE-SAFE® preventive occupant protection system is available for the first time in the A-Class. This marks the debut in the compact class of this innovation which was premiered in the S-Class back in 2002.
E 300 BlueTEC HYBRID: the world's most fuel-efficient luxury-class model
The new E 300 BlueTEC HYBRID is all set for its market launch with record efficiency values of 4.2 l diesel/100 km and 109 g CO2/km, accompanied by increased torque and power output. Its modular hybrid concept with lithium‑ion battery does not impose any compromises on space and offers an impressive driving experience thanks to start/stop, recuperation, boost effect, all-electric driving and sailing. The E 300 BlueTEC HYBRID is the world's most fuel-efficient model in the luxury segment.
Mercedes-Benz is setting new standards for luxury-class business vehicles: the E 300 BlueTEC HYBRID, which is available as a saloon and an estate, boasts truly impressive performance. Its 4-cylinder diesel engine generates 150 kW (204 hp) of power and 500 Nm of torque. The diesel engine combines with an electric motor rated at 20 kW and 250 Nm to produce a harmonious overall concept.
"The E 300 BlueTEC HYBRID represents the continuation of our comprehensive hybrid offensive. The modular technology paves the way for us to quickly introduce hybrid models to complement other model series," explains Professor Dr Thomas Weber, Daimler Board Member for Group Research and Head of Mercedes-Benz Cars Development. "By clearly focussing on the different requirements of the global markets, we are able to offer precisely the models that our customers want."
The new SL-Class: light, athletic, luxurious
The all-new SL sees Mercedes-Benz continuing a tradition that began 60 years ago, since when "SL" has always stood for a symbiosis of sportiness, style and comfort – and for trailblazing innovations. The SL consists almost entirely of aluminium for the first time and weighs in at up to 140 kilograms lighter than its predecessor. The highly rigid all-aluminium body-in-white provides the basis for emphatically sportier, agile handling accompanied by exemplary ride and driving comfort.
New BlueDIRECT engines provide for enhanced driving dynamics; they are more powerful and at the same time up to 29 percent more fuel-efficient than the previous generation of engines. Totally new features are the Frontbass system, a world-first that transforms the luxury sports car into a concert hall irrespective of whether the top is up or down, and the MAGIC VISION CONTROL adaptive wiper/washer system, which applies water to the windscreen from the wiper blade in the required quantities and according to the wiping direction.
SL 63 AMG: high-performance roadster
The latest version of the Mercedes-Benz SL 63 AMG high-performance roadster impresses on several counts: systematic lightweight construction, increased output and enhanced driving dynamics, all combined with a 30 percent reduction in fuel consumption and emissions. Thanks to an all-aluminium bodyshell, similar to that of the SLS AMG supercar, the vehicle has shed 125 kilograms. With a kerb weight of 1845 kilograms and an output of 395 kW (537 hp) or 415 kW (564 hp), the new model boasts the perfect ingredients for unparalleled dynamism and a sublime driving experience that is truly unique.
A further boost in performance comes courtesy of a winning combination: a further improved AMG sports suspension based on Active Body Control, new AMG speed-sensitive sports steering, the AMG high-performance compound braking system and the AMG SPEEDSHIFT MCT 7-speed sports transmission. An enticing mix of stylish design, extensive standard equipment and a high level of safety.
Intelligent lightweight construction is one of the major factors behind the low fuel consumption figures. The SL 63 AMG is built around a lightweight all-aluminium bodyshell similar to that of the SLS AMG supercar. Compared to the outgoing model, this design not only delivers a weight reduction of around 110 kilograms, it also greatly enhances rigidity, safety and comfort. The boot lid helps to further trim the weight. For the first time on a volume-produced model, the inner support is made from lightweight carbon-fibre composite. The extremely rigid carbon-fibre component is bonded to the plastic outer shell, resulting in a weight saving of five kilograms compared to a conventional boot lid.
SLK 55 AMG: top figures in all disciplines
The Mercedes-Benz SLK 55 AMG is the most powerful SLK of all time. Its newly developed naturally aspirated AMG 5.5-litre V8 engine with cylinder shut-off system combines ultimate performance with minimised fuel consumption. With a maximum output of 310 kW (422 hp) and peak torque of 540 Newton metres, the SLK 55 AMG outperforms all of its direct competitors. The SLK 55 AMG accelerates from zero to 100 km/h in 4.6 seconds, and reaches a top speed of 250 km/h (electronically limited). Its fuel consumption of 8.4 litres per 100 kilometres (NEDC combined) and CO2 emissions of 195 grams per kilometre are some 30 percent lower than the figures for its predecessor.
ML 63 AMG: efficiency and superlative performance
The new Mercedes-Benz ML 63 AMG stands for efficiency and performance, exclusivity and a superlative driving experience. Burning 11.8 litres of fuel per 100 kilometres (NEDC combined, 276 g CO2/km), the high-performance SUV undercuts its predecessor by 28 percent. The basis for the low fuel consumption and top-class performance is provided by the AMG 5.5-litre V8 biturbo engine. The eight-cylinder unit extracts a maximum power output of 386 kW (525 hp) and 700 Newton metres of torque from its displacement of 5461 cc. In conjunction with the AMG Performance package, these figures rise to 410 kW (557 hp) and 760 Newton metres. Both variants of the ML 63 AMG deliver sports car-like performance: the sprint from 0 to 100 km/h takes 4.8 seconds and 4.7 seconds respectively, while top speed stands at 250 km/h (electronically limited).
C-Class Sport: the C-Class has never been sportier
Mercedes-Benz is sharpening the profile of the C-Class: with the new "Sport" Coupé models developed with AMG and the new "AMG Plus Sports package", there has never been a wider choice of sporty versions. The new models are available from June 2012. The AMG Plus Sports package can be combined with all body and engine variants.
The name says it all – the new coupé models C 250 Sport and C 250 CDI Sport are decidedly dynamic, as the performance specialists at AMG were heavily involved in their development. In addition to the visually enhanced AMG Plus Sports package, both models have technical features which further increase driving enjoyment. Cornering and handling characteristics are more dynamic thanks to an AMG sports suspension, more direct speed-sensitive sports steering, a sports exhaust system and a more sporty transmission configuration in S and M mode. The matt paint finish "designo magno platinum" is exclusively available for the Sport models.
C 180, E 220 CDI BlueEFFICIENCY Edition: shining beacons of efficiency
Presenting the most economical E-Class diesel and C-Class petrol models to date: with fuel consumption of 4.5 litres/100 km and emissions of 119 g CO2/km for the
E 220 CDI BlueEFFICIENCY Edition and 5.8 litres/100 km and 136 g CO2/km for the new C 180 BlueEFFICIENCY, Mercedes-Benz is giving an impressive demonstration of just how much potential is still left in the internal-combustion engine. Take the
C-Class, for instance: since its predecessor was launched in 2000, the output of the
C 180 has increased by 21 percent, whilst consumption has been reduced by 37 percent. The present version of the C-Class is nearly twice as efficient as its predecessor.
The E 220 CDI BlueEFFICIENCY Edition that is available from March 2012 is simply one of the most economical cars in its segment. Thanks to a bundle of efficiency-boosting measures, including an Aerodynamics package, electric power steering (EPS), a longer final-drive ratio and size 205/55 R 16 tyres with low rolling resistance, the model emits just 119 g CO2/km – ten grams or nearly eight percent less than before and equates to 4.5 litres of diesel per 100 km. The E 220 CDI BlueEFFICIENCY Edition has an output of 125 kW (170 hp) and is available with a 6-speed manual transmission only.
The turbocharged 1.6-litre four-cylinder petrol unit is the brand new entry-level engine for the C-Class. With fuel consumption of 5.8 l/100 km and a CO2 figure of 136 g/km, the improvement compared to the previous C 180 when similarly equipped is as much as 21 g/km, or just under 1 l/100 km. This makes the C 180 BlueEFFICIENCY one of the very first petrol models to be ranked in energy efficiency class B. The 115 kW (156 hp) engine is very light when compared to its competitors and delivers impressive agility from standstill – peak torque of 250 Nm is on tap from just 1250 rpm all the way up to 4000 rpm.
CL "Grand Edition": exclusive luxury
The exclusive "Grand Edition" of the CL from Mercedes-Benz features attractive exterior paint finishes and more exclusive interior appointments. The range of paint finishes offers a choice between designo platinum black metallic, designo magno cashmere white and designo mocha black.

Mercedes-Benz is opening a new chapter in its brand's core segment and at the same time setting new standards for luxury-class business vehicles: the E 300 BlueTEC HYBRID, which is available as a saloon and an estate, boasts truly impressive performance. The 4-cylinder diesel engine of the E 300 BlueTEC HYBRID is rated at 150 kW (204 hp) and 500 Nm. The diesel engine combines with an electric motor rated at 20 kW and 250 Nm to produce a harmonious overall concept.

"By clearly focussing on the different requirements of the global markets, we are able to offer precisely the models that our customers want."
The new model does not force passengers to compromise in terms of spaciousness, either in the interior or in the luggage compartment. The intelligent, modular hybrid concept represents a comprehensive enhancement of the S 400 HYBRID – the clear market leader in its segment: no body modifications are necessary, the hybrid module is flexible and also suitable for deployment in other model series. All this comes at only a moderate price increase of € 3570. In Germany the E 300 BlueTEC HYBRID costs € 51,794.75 as a saloon, while the estate model retails at € 55,007.75 (in each case incl. 19% VAT). Both models are to be launched in June 2012.
The philosophy: enhanced efficiency without compromising on comfort or benefits
The E 300 BlueTEC HYBRID forms part of the brand's intelligent downsizing strategy, which involves making conventional models far more efficient than previously – without sacrificing driveability or comfort.Here the in-house engineers have their sights set on exemplary consumption figures in everyday traffic rather than on standard or NEDC combined consumption, for instance. The familiar "Real Life Safety" philosophy, which focuses on safety benefits under real-life conditions rather than standardised crash-test results, is augmented by "Real Life Efficiency".
The E 300 BlueTEC HYBRID is based on the notoriously economical E 250 CDI, yet has a higher output and 15 percent lower fuel consumption.Overview of the E 300 BlueTEC HYBRID:
On the road, therefore, the E 300 BlueTEC HYBRID is easily a match for the E 300 CDI (170 kW/540 Nm), yet it boasts around 35-percent lower fuel consumption and CO2 emissions.In terms of vehicle weight, too, the E 300 BlueTEC HYBRID is on a par with the E 300 CDI.
At the same time, hybridisation enhances ride comfort:the car starts and moves off in virtual silence, while the hybrid module also damps any internal combustion engine vibrations. What's more, complete climate control is available even in start/stop mode.
Coasting along the motorway
Mercedes-Benz hybrid technology offers a wealth of extra functions that enhance both comfort and efficiency as well as helping to deliver a special driving experience underpinned by accomplished sportiness:
- When the car is stationary - ECO start/stop: the internal combustion engine switches off when coasting at speeds up to 160 km/h, since ancillaries such as the steering, brakes and refrigerant compressor operate electrically. It is restarted quickly, smoothly and virtually silently.
- Manoeuvring: in most cases, the car uses electric power alone for manoeuvring and parking.
- Accelerating: electrical power alone is used for moving off and driving under low load. Acceleration from standstill is particularly powerful, since the electric motor's full torque of up to 250 Nm is available instantaneously.
- Boost function: the electric motor supports the combustion engine during acceleration, e.g. in the course of overtaking.
- Cruising: when the car is being driven at a constant speed, the engine control unit shifts the operating points towards exceptionally low specific fuel consumption levels.
- Sailing "sailing", as it has come to be known, is possible at speeds below 160 km/h. The combustion engine shuts down and the desired speed is maintained by the electric‑motor alone until the battery needs recharging.
- Kinetic energy recuperation when coasting or braking: when the car is coasting (decelerating), the electric motor acts as a generator. When the brake pedal is pressed, the generator output is initially increased proportionally for greater deceleration. Only when increased brake pressure is applied are the wheel brakes additionally deployed.
- Information: an additional savings effect arises after a relatively short period of time, as drivers come to apply the above-stated functions in an increasingly more purposeful and effective manner. They are supported here by the display concept in the hybrid models – the central display provides information on the current energy flow and the charge status of the battery.
The hybrid module: a compact and intelligently integrated powerhouse
The hybrid drive unit is a further development of the module from the S 400 HYBRID and is based on the 7G-TRONIC PLUS automatic transmission.Distinguishing features include the omission of the hydraulic torque converter and the addition of a wet clutch of the kind also found in the high-performance AMG models. Consequently, the electric motor can be integrated in the transmission unit in such a way that it takes up only marginally more space than the 7G-TRONIC (+65 mm). The omission of the converter allows all-electric motoring as well as "sailing", thus significantly boosting the potential to reduce fuel consumption.
The compact electric motor, which is installed in space-saving configuration in the clutch housing between engine and transmission, is a 3‑phase AC internal rotor magneto motor which generates a maximum output of 20 kW and peak torque of 250 Newton metres at an operating voltage of 120 volts.
The components: perfectly integrated into the vehicle
The hybrid drive's electrical energy is provided by the high-voltage lithium-ion battery specially developed for use in vehicles.Its key characteristics include an output of 19 kW and an energy content of 0.8 kWh, allowing the E-Class to run on electric power alone at up to 35 km/h and for up to one kilometre. Space-saving installation of the drive in the engine compartment in place of the conventional starter battery means that the generous interior dimensions and the luggage compartment capacity remain unchanged. In addition to serving as an energy accumulator for the electric motor, the lithium-ion battery is also connected via the voltage converter to the 12V on-board electrical system, which supplies power to standard power-consuming devices such as the headlamps and the comfort features.
Sophisticated packaging means that numerous hybrid-specific components such as the high-performance electronics in the engine compartment can be integrated directly with the internal combustion engine, thus neatly rounding off the modularity concept:the hybrid models can be produced on the same assembly line as their conventional counterparts without needing to be diverted elsewhere. Another advantage of the overall concept is the scalability and compatibility with other vehicles and engines.
Safety: on a par with previous models
Intelligent integration of the hybrid systems without the need for changes to the body has the practical benefit of not restricting spaciousness in any way as well as ensuring that all hybrid models boast exactly the same high level of safety as their counterparts with an internal combustion engine – a very important aspect for Mercedes-Benz. Accident behaviour has been successfully tested crash simulations and tests.
