The new Mercedes-Benz SL 63 AMG: Design and equipment - New AMG brand face

By | Published Tuesday, 8 May 2012

The top-of-the-range AMG model is once again playing a leading role - this time in terms of design. The SL 63 AMG is the first high-performance model to feature the new brand face. The two elements which dominate the form – the radiator grille and the lower cooling air intake – are retained but in reinterpreted form which gives them a more distinctive identity in terms of dynamism and the sense of perceived value they convey. The central styling feature is the new "twin blade" radiator grille in silver chrome. The Mercedes star is mounted on two blade-like louvres whose profile recalls that of an aircraft wing. The more pronounced V-shape of the radiator grille optimises the longitudinal proportions of the vehicle and so adds even greater visual emphasis to the attributes of aerodynamics and purism.

Below the radiator grille with its twin blades, the stylised "A" - a characteristic feature of AMG vehicles - is retained. A gap formed below a fine black fin at the lower edge of the cooling air opening allows optimum airflow over the cooling modules – a perfect combination of aesthetics and high technology. The lower cross strut in the front apron is also finished in silver chrome and is given a perceived sense of depth by the gap above it – a distinctive note which adds the perfect finishing touch to the front of the vehicle. The "twin blade" radiator grille and lower cross strut are the two complementary styling elements which underline the new AMG brand face – a look which will be picked up by the styling of future AMG models and so further increase the recognition value of the AMG performance brand.

AMG bodystyling with characteristic features

The SL 63 AMG boasts classic sports car proportions: the long bonnet, compact passenger compartment set well back, and the powerful rear are all combined skilfully with the characteristic AMG bodystyling features. These include the front apron with black grilles and large openings for engine oil, water, charge air and transmission oil coolers, the side skirt panelling and the exciting profile of the diffuser-style rear apron with body-coloured insert. The standard-specification ILS headlamps are characterised by very high-quality tubes for the low and main beam which have been styled with great attention to detail, plus a chrome bracket surrounding the main headlamp and the flared arrangement of the indicator lamps and sidelights. All of the further functions feature LED technology – such as the distinctively curved sidelights. The surrounds of the special AMG daytime driving lights, the side fins on the wings and the fins on the bonnet have the same silver-chrome finish as the radiator grille and the lower strut in the front apron.

The side profile is dominated by the "V8 BITURBO" logos and the titanium grey-painted 5-twin-spoke AMG light-alloy wheels with high-sheen finish. The front axle is fitted with 255/35 R 19 tyres on 9.0 x 19 rims, while the rear has 285/30 R 19 tyres on 10 x 19 rims. A highlight at the rear is the AMG sports exhaust system, with its two chromed twin tailpipes integrated into the bumper. The AMG spoiler lip helps to reduce lift on the rear axle while increasing driving stability at high speeds.

Exceptional quality of interior finish

The interior of the SL 63 AMG is characterised by the typical wrap-around effect, as already featured in the CLS 63 AMG: in conjunction with the beltlines on the doors and the parcel shelf, the upper section of the dashboard creates a formal unity. The generous amount of space, high-quality materials, high sense of perceived value and lovingly crafted details displaying tangible and visible precision all exude a sense of ultimate quality. Minimal gap dimensions please the eye and reflect the high precision with which the SL has been produced.

A delight for all of the senses: this comes courtesy of the specific style elements, familiar from the SLS AMG, such as the four air vents in the style of jet engines, the AMG DRIVE UNIT - exclusive to AMG - and the leather-clad E-SELECT selector lever with embossed AMG badge. To the left of the selector lever are three buttons: the front button operates the 3-stage ESP® system, the centre button controls the AMG sports suspension based on Active Body Control, while the rear button with the AMG symbol is used to store personal settings (transmission mode, suspension mode, ESP® function). Pressing briefly on the AMG button enables the configuration options to be called up, while holding down the button longer allows the desired setup to be chosen, as confirmed by means of an audible signal. In addition, pressing a button at any time also displays the chosen setup in the instrument cluster.

AMG main menu and AMG Performance steering wheel

Two tube-shaped round cockpit instruments provide information on engine rpm and tank capacity (left), and road speed and coolant temperature (right). Three-dimensional graduated rings, back-lit dials in the centre of the speedometer and rev counter, AMG-specific red dials and the 360 km/h speedometer scale all add to the emotional appeal. The driver is greeted by an AMG start-up screen which appears in the centrally located three-dimensional TFT colour display. The AMG main menu is also integrated into the central display: three modes of "Warm Up", "Set Up" and "RACE" provide the driver with comprehensive information. "Warm Up" displays the engine oil and coolant temperatures as well as the operating status of the ECO start/stop function; "Set Up" provides information on the current ESP® mode, suspension mode and the transmission modes "C", "S", "S+" or "M". In "RACE" mode, the RACETIMER becomes available. The driver can use this to record lap times on a closed-off racing circuit. The gear display is located above the central display.

A visual and tactile highlight of the interior of the SL 63 AMG is the new AMG Performance steering wheel: specially shaped grip areas finished in perforated leather, together with flattened top and bottom sections, help to ensure perfect control of the vehicle. Aluminium shift paddles enable manual shifting. The bottom end of the galvanised spokes features an AMG logo for the first time. The airbag cover, which has a three-dimensional shape, is finished in nappa leather. Twelve function buttons allow the audio and navigation system, the driver assistance systems, the on-board computer and the AMG main menu to be controlled.

Optional nappa leather in four different colours

First-class comfort on long journeys and high levels of lateral support come courtesy of the electrically-adjustable AMG sports seats. They not only feature a distinct V8 seat upholstery layout and AMG badges on the seat backrests, but also 4-way lumbar support, memory function, seat heating and a multicontour function: this allows the seat cushion length and side bolster support to be adjusted. The nappa leather upholstery covers the armrests in the doors and centre console, and includes stitching and edging in contrasting colours. Optional colours range from black, porcelain and Bengal red, to ginger beige/espresso brown. For an even higher quality ambience, Exclusive nappa leather is also available as an option: it includes a nappa leather finish on the dashboard, door panelling, rear compartment panelling and parcel shelf. Contrasting stitching and a roof lining, including A/C pillars finished in DINAMICA microfibre are also included.

The standard ambient lighting bathes the interior in a pleasant indirect light. Three colours (SOLAR, SOLAR red and SOLAR orange) are available to choose from. The fibre-optic cables offering three colour options are fitted on a level between the beltline and door centre panel, almost along the entire length of the doors, behind the trim for the dashboard and in the front panelling. An exclusive highlight reserved for the SL 63 AMG is the AMG-specific analogue clock, located centrally on the dashboard and featuring an IWC design.

The standard equipment on the SL 63 AMG includes AMG carbon-fibre trim, which affords the interior an appealing motorsport feel. Optionally available at no extra cost are aluminium trim elements with a dark or light longitudinal-grain, and also wood trims in high-gloss black ash, light-brown satin or high-gloss brown finishes.

Further standard equipment for the SL 63 AMG at a glance (selection):
- AMG door sill panels in brushed stainless steel with white illumination

Bang & Olufsen BeoSound AMG high-end surround sound system

An attractive highlight among the optional extras for the SL 63 AMG is the Bang & Olufsen BeoSound AMG high-end surround sound system, as found on the SLS AMG: Mercedes-Benz and AMG have created it in conjunction with famous Danish audio specialists Bang & Olufsen. The sound system enables an exclusive music experience to be enjoyed at the very highest level. The basis of the system is formed not only by the amplifier with a total output of 900 watts and 12 high-end loudspeakers including Frontbass, but also the precise distribution of the music signals, controlled by the sound processor, to the selectable seating positions of driver, front passenger or the central position.

Thanks to the digital sound processor (DSP), it is also possible to choose between the high-end "reference" studio sound and spacious surround sound. All of the functions are operated using the COMAND system via a special Bang & Olufsen menu. Particular highlights include the illuminated lens tweeters on the dashboard – they help to create the characteristic virtual sound stage in front of the vehicle occupants. High-quality aluminium loudspeaker covers finished in silver chrome with the Bang & Olufsen logo give an indication of the exceptional position enjoyed by this high-end system.

The new Mercedes-Benz SL 63 AMG: Body and lightweight design - Aluminium comes up trumps

By

Cars are becoming increasingly safer, more comfortable, but often heavier as well. The new Mercedes-Benz SL 63 AMG not only stops this trend, it turns it around. In spite of increased comfort, performance and safety, it weighs 125 kilograms less than its predecessor.

The greater part of the weight-reduction "diet" is hidden from the eyes of the observer of the SL. Under the aluminium outer skin there is a bodyshell made almost entirely from aluminium, only very few components being made from other materials. The even lighter magnesium is used in part for the cover behind the tank. The A-pillars and the roof frame are of steel sheet metal incorporating high-strength steel tubing. For these elements steel is the best solution to provide survival space for occupants in the event of the vehicle overturning.

The body of the SL is the first all-aluminium bodyshell to be produced in large series at Mercedes-Benz. This entirely new development weighs 254 kilograms and is thus 110 kilograms lighter than a comparable steel bodyshell. Further extensive lightweight design features compensate the additional weight unavoidably caused by the increased comfort, the new assistance systems and other technical features. The bottom line is that the new SL 63 AMG retains an enormous weight advantage: it weighs 1845 kilograms, while its predecessor of the same tipped the scales at 1970 kilograms (all figures are kerb weights according to EC).

Bodyshell: converting the entire bodyshell to aluminium cuts its weight by 24 percent in contrast to a steel bodyshell featuring comparable properties - a weight saving of 110 kg. Even the upper door hinges consist of aluminium.

Damping: the switch from absorber foams to sprayable acoustic compositions with variable layer thicknesses which can be shaped according to requirements, plus modified underbody panelling, results in a weight saving in the order of 2.5 kg.

Guide rails for the window lift mechanisms: these are now comprised of aluminium instead of steel, amounting to a weight saving of 0.5 kg.

Vario-roof in magnesium/plastic design: the front part of the roof and the C-pillar are produced in magnesium/plastic, plus there are additional optimisation measures regarding the design of the tubular frame, rear shelf, rear window frame and roof frame. The weight saving amounts to 15 kg.
Glazing: windscreen is 0.5 millimetres thinner, with an acoustic film. Weight reduction of over 1 kg. The rear window is 0.7 millimetres thinner. Weight saving is approx. 1 kg.

Interior: the dashboard mount consists of a continuous IHP (internal high-pressure forming) aluminium tube with magnesium struts and moulded-on polymer brackets. The weight saving is 2.2 kg.

With the introduction of shift-by-wire technology, the previous shift lever has been replaced by the E-SELECT selector lever in the AMG DRIVE UNIT. This weighs only one sixth as much as the solution used in the preceding model. The weight saving is 1.4 kg.

Boot: the boot floor is in the form of a polyurethane honeycomb plate instead of the wood plate previously used. The passenger’s foot plate has been switched over to plastic from steel, saving 1.5 kg in weight.

Seats: new seat structure with new adjustment motors, but standard-fit 4-‑way lumbar support and cash-responsive head restraints. Weight saving: 11 kg. 

Electrics: thanks to an intelligent dynamic load management system, two large batteries are no longer necessary; one 95 Ah battery in the boot is sufficient, supported by a 12 Ah battery for the ECO start/stop function. Weight saving: approx. 4 kg.

Every vehicle is given a customer-specific wiring harness for the interior, cockpit and engine compartment. Thanks to this tailor-made cable harness, additional weight in the form of wires which are surplus to requirements can be saved – to the tune of up to 0.4 kg.

The innovative Frontbass system avoids the need for a separate woofer and door loudspeaker. Weight saving of over 4 kg.

Axles: the four-link front axle had already undergone extensive weight optimisation for the preceding model, featuring steering knuckles and spring links made of aluminium. The two front-axle halves now consist entirely of this material. The integral support frame for the front-axle halves, steering gear and engine is also produced in aluminium. Total weight savings are 11 kg.

For the roadster the aluminium bodyshell is superior to a steel construction

The developers at Mercedes-Benz did not rest content achieving weight benefits alone. The aluminium structure had to be superior to a steel construction in terms of rigidity and comfort as well. In order to attain this high objective, developers consistently went for intelligent lightweight construction, and explored many new paths to do this. Every single component of the aluminium bodyshell was specifically optimised for its particular function and expected loads. Thus, diverse processes are used to make different kinds of aluminium depending on the use the component is to be given: the parts are made by chill casting (metallic reusable casting mould) or vacuum die casting, worked into extruded aluminium sections or into aluminium plates of thicknesses that vary within one and the same component; these are the so-called tailored welded blanks. Expressed in numbers, the bodyshell weight is made up of: 44% cast aluminium, 17% aluminium sections, 28% aluminium sheet metal, 8% steel and 3% other.

The parts are assembled using diverse load-adequate joining methods at the production facilities in Bremen, some of which are innovative processes. Secure joints are ensured, for example, by MIG (metal inert gas) welding, hemming, bonding, self-piercing rivets, flow hole bolting, or friction stir welding – a joining method by which a highly resistant weld seam is produced by means of friction heat; a method particularly well-suited to aluminium on account of its low melting point.

Particular highlights of the bodyshell:
- the firewall is at present the largest aluminium cast component made in large series for vehicle bodywork

- many sheet metal parts are designed in such a way that for the first time they can be made from 100-percent recycled aluminium, saving 80 percent of the energy used in their production

- the main floorpan consists of a 3-layer shaped panel made from thin, extrusion-moulded hollow sections, welded together by friction stir welding

- the longitudinal members in the vehicle front end are made using internal high-pressure forming (IHP) technology, which enables the creation of highly complex and robust components, permitting optimum use of reduced installation spaces

- the door sills (longitudinal members) consist of 1.7-metre-long, 7-chamber extrusion-moulded aluminium sections; these provide rigidity in the lateral sectors and safety in the event of a collision. Flexible chamber distribution makes possible a minimum component weight coupled with optimum characteristics

- the tunnel is made of aluminium sheet metal with a reinforcement of varying thickness (3 different thicknesses depending on the sector, a so-called tailored welded blank, TWB)

- the rear sector floor is a MIG welded frame with a hollow chilled cast longitudinal member as its central element. This technique is employed in the SL for the very first time in automotive bodyshell construction

- the rear sector floor frame structure is closed by floor sheet metal panels and the boot tub made by vacuum die-casting

- the boot recess is made from recycled sheet metal

- the central member connects the front end with the rear sector floor. The mounting points for the drive shaft, the transmission cross beam, the transmission tunnel braces and the seat bolting points on the tunnel side are all integrated into a single element. The wall thicknesses and rib distribution are oriented bionically towards the requirements and loads

- many other components were optimised bionically, i.e. based on examples from the natural environment. These structures reduce the vehicle weight compared to a classic design even further

The sum total of all the design measures leads to a lightweight, torsionally and flexurally rigid bodyshell with an optimum rigidity/weight ratio. It was possible to increase the bodywork’s torsional rigidity by more than 20 percent over the already highly rigid preceding model series. This is confirmed by measurements of the new SL’s torsional strength – at 19,400 Nm per degree the roadster achieves an absolute top value (its predecessor already reached 16,400 Nm per degree).

Meeting the highest safety standards

At the same time the high-strength structural elements of the aluminium bodyshell make the new SL even safer than the preceding model in the event of a collision. Extrusion-moulded sections, connecting cast nodes and a double-thickness plate floor form a passenger compartment that is just as lightweight as it is sturdy. Two aluminium sections in each door together with the side sills (very rigid thanks to their internal chamber structure) and crash-resistant seats provide the greatest possible survival space in the event of a side collision.

A front end deformation zone acting on several levels and in which the aluminium front axle subframe is integrated as an additional third longitudinal member, distributes collision forces to a large area, conducting them past the passenger compartment. And in the rear, too, there is sufficient energy-absorbing deformation potential. A structural cage made from chilled cast longitudinal members, transversal sections and a cast magnesium tank separation bulkhead also contribute to this. This is also where the fuel tank is nested in a crash-protected manner above the rear axle. This way all the statutory safety requirements are met as well as the even stricter ones from Mercedes-Benz.

Best marks for NVH comfort

Thanks to its innovative aluminium bodyshell concept, the new SL is also unique among the roadsters in terms of NVH comfort (noise, vibration, harshness). One contributing factor towards its optimum vibration and road roar characteristics is a very rigid connection between the front section and rear floor, allowing relaxing travel even over long distances, and at the same time offering impressive driving dynamics.

Although aluminium features a higher sound emission and radiation level than steel, the new SL is the quietest vehicle in its class. Mercedes-Benz compensates for the acoustic disadvantages of aluminium by means of a consistent sound insulation concept with targeted adaptation of the sound damping materials to each problem zone, and through the use of innovative sound-insulation materials:
- a special firewall damping with variable mass distribution and a significant heavy layer proportion attenuates engine noise

- in conjunction with the plate floor, single-piece, foam-backed carpeting with virtually no seams reduces the roll noise of the vehicle in the interior

- a spray-on lining attenuates the structure-borne sound in the interior and exterior of the vehicle

- textile wheel arch linings, acoustically absorbing shield plates and bodyshell foam elements for critical sectors also contribute towards a smooth ride

- damping in the rear wall transversal cross member and boot lateral elements as well as in the forced ventilation openings prevent disruptive tyre and wind noises from making themselves unpleasantly noticeable in the vehicle interior

A further contribution to the good interior acoustics is the laminated glass windscreen with acoustic film. The transparent, highly resilient film absorbs the vibrations of the windscreen and reduces the perceptible sound level in many frequency ranges.

The precision workmanship on the acoustics goes so far as to ensure that the hydraulic pump for the electrohydraulic vario-roof is encapsulated and decoupled from the bodyshell. In addition to this, a newly developed insert nozzle sees to it that the pressure pulsation in the pump is reduced to a minimum right from the outset. This means that pump noises are only barely audible for the driver and passenger.

Boot lid made of carbon-fibre composite material for the first time

The intelligent material mix is completed by the boot lid: for the first time in large-scale production, the internal support is made of lightweight carbon-fibre composite material. The extremely rigid carbon-fibre component is bonded to the plastic outer shell, resulting in a weight saving of five kilograms compared with a conventional boot lid. The innovative solution is being used for the very first time in the SL 63. As such, Mercedes-Benz is consistently continuing with its "AMG Lightweight Performance" strategy, first presented at the Frankfurt Motor Show in September 2011. The plastic panelling allows the aerials for navigation, digital radio and mobile telephony to be fully integrated out of sight in the rear area, so that the SL 63 AMG does not need to include a bothersome aerial stump on its aerodynamically refined body.

The bonnet is made from aluminium, as was that of its predecessor. It has been optimised in terms of form and materials, contributing towards the outstanding pedestrian protection. The doors, too, are of a lightweight design and made from aluminium. They are fashioned from a combination of sheet metal, extruded sections and cast metal parts, joined by diverse methods: riveting, bonding and hemming. Their aluminium and steel hinges are friction-based and are infinitely adjustable to any desired angle when opened, so that when getting into or out of the car they can remain securely open at any angle permitted by the space available at the side. This is particularly desirable in cramped parking conditions such as in a garage or car park.

Unique item of equipment: MAGIC SKY CONTROL

The proven electrohydraulic vario-roof – which turns the roadster into a closed coupé with a fixed roof in just a few seconds at the push of a button – has been intelligently enhanced, with Mercedes-Benz continuing to play the pioneering role here. For the new SL Mercedes-Benz is for the very first time offering drivers the choice between three variants of the lightweight-construction vario-roof:
- the base version is a roof painted in the vehicle colour

- as an alternative, a transparent variant with a roller blind can be selected

- the third variant from which drivers can choose is the panoramic vario-roof with MAGIC SKY CONTROL. This glass roof switches to light or dark as required at the press of a button. When light 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 when the sun’s rays are very intense. In other words: a feel-good atmosphere at the touch of a button

The operating principle is based on the physics of a plate condenser: if the glass structure is subjected to an electrical voltage, particles in the structure position themselves so that light is able to pass through the glass. If the voltage remains switched off, however, the particles position themselves randomly. This partially blocks the light, and the glass remains dark. The control unit and converter are integrated into the front section of the roof, and the switch is in the overhead control console.

In addition to the unique panoramic effect and transparency at the touch of a button, MAGIC SKY CONTROL also provides an atmosphere of wellbeing. UV and infrared light are also effectively blocked in transparent mode, while insulation increases even more significantly in the darkened mode, thereby helping to keep the temperature on interior parts such as armrests cooler by up to ten degrees Celsius compared with conventional green glass.

Since the innovative glass also shields against the sun’s rays far more effectively than conventional thermal insulation glass or sunblinds, the occupants of the new SL will also enjoy the highest level of climatic comfort at the same time. When driving with the roof open would be unpleasant due to intense heat, the driver and passenger are able to remain composed under the MAGIC SKY CONTROL roof – making an important contribution towards driver-fitness safety, a concept which Mercedes is well known for promoting. Even when the vehicle is at a standstill the interior does not overheat, since the roof is switched to darkened mode when powered off.

But MAGIC SKY CONTROL not only benefits the occupants. Some of the strain is also taken off the air conditioning, thereby saving on CO2 emissions. The frame of the three roof variants is now made of magnesium. This makes each roof around six kilograms lighter than in the previous model, giving the car a lower centre of gravity, and therefore better agility. The engineers have refined the operating mechanism for the roof and boot lid. It now takes less than 20 seconds to open or close the roof completely.

Sophisticated corrosion protection concept

The aluminium bodyshell of the new SL offers no point of attack for corrosion. A sophisticated surface protection concept ensures the preservation of the brilliant look both of the outside skin and of the underside of the sheet metal panels, thus simultaneously protecting the renowned reliability and value stability of Mercedes-Benz vehicles. The protection concept was developed and tested on the basis of the environmental burden in different climate zones of the world and the specific loads the vehicle is subjected to.

The foundation for maximum corrosion resistance is formed by corrosion-resistant aluminium alloys and design features, while the few steel vehicle components are all fully galvanised. High-quality zinc/nickel coatings or special electrochemical insulation measures prevent contact corrosion with aluminium. All the seams are meticulously sealed, the surfaces protected through cathodic dip priming and multiple coats of paint. Sectors particularly exposed to corrosion are additionally protected with wax, to ensure that the pristine aspect of the new car is preserved for a long time.

Intelligent Light System and LED tail lights as standard

The headlamps on the new SL have been enhanced. As part of its standard specification, the new roadster is equipped with the Intelligent Light System (ILS) featuring bi-xenon headlamps. A driving direction indicator, sidelights and the daytime running lamps with LED technology complete the Intelligent Light System.

The tail lights on the new SL benefit from the advantages offered by the LED technology. LEDs light up approximately 150 milliseconds faster than conventional bulbs, plus they have a considerably longer life and conserve current. In the SL’s tail lights, the LEDs also light up with differing intensity in a targeted manner in certain sections of the tail lights, depending on the light function. This technology ensures an unmistakable night design. Rear reversing lights and rear fog lamps are integrated into the AMG rear apron featuring a diffuser look. The third brake light, which makes use of LED technology, is located in the boot lid above the Mercedes star.

The development of the Mercedes-Benz A-Class: The work methods of Mercedes-Benz Design

By

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.

The development of the Mercedes-Benz A-Class: The Advanced Design Studio in Como/Italy

By

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.

The development of the Mercedes-Benz A-Class: The philosophy - Design as a trademark

By

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.

The development of the Mercedes-Benz A-Class: The design - Interview with Mark Fetherston

By

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.
