Stuttgart, Mar 23, 2005
The New York International Auto Show is to provide the stage for another world premiere from Mercedes Benz, 51 years after hosting the unveiling of the legendary SL gullwing. Now it is the turn of the new Mercedes Benz R Class to make its world debut at the traditional show.
The unique vehicle concept at the heart of the Mercedes model founds a new and highly promising "Sports Tourer" market segment. "Our developers had no role model to follow when they created this totally new vehicle. But they did have a guiding principle: dynamic space", says Dr. Thomas Weber, Member of the Board of Management DaimlerChrysler AG, responsible for Research and Technology and Development within the Mercedes Car Group.
The R Class Grand Sports Tourer takes the acknowledged strengths of established vehicle categories, such as sporty Saloon, Estate, MPV and SUV, and fuses them to create a new car with a character all of its own. It caters to the needs of modern minded people looking for a car that offers tremendous versatility combined with athletic performance. Quite apart from boasting ample spaciousness, exemplary standards of safety and impeccable comfort for up to six passengers, the new R Class also enthrals with its beguiling styling, prestigious flair and, last but by no means least, its dynamism out on the road.
"The new R Class is 'inspired by and built in America' and is therefore very much at home in the U.S. market", says Dr Thomas Weber. "Here we expect to achieve some 60 percent of our unit sales after the market launch in autumn 2005." Deliveries to customers in Europe will begin in early 2006.
According to Dr Weber, it takes three Ds to sum up the unique character of the R Class: Dimensions, Design and Dynamism. "Dimension refers to the synthesis of exceptional spaciousness, premium comfort and high variability. The design reflects power, confidence and individuality. And the R Class is as dynamic as it looks – thanks to powerful engines, a seven-speed automatic transmission and permanent all wheel drive."
Measuring 5157 millimetres from nose to tail, the body of the new Mercedes Benz R Class is akin to a luxury saloon in size but is considerably more spacious inside. There are 920 millimetres between the first and second rows of seats. Moreover, the second-row seats can be adjusted individually fore and aft, thereby increasing the seat spacing to as much as 990 millimetres. The maximum distance between the second and third rows of seats (depending on seat position) is 920 millimetres.
Families who are keen on sports and recreational activities and who are looking for a versatile car that can adapt to all manner of transportation tasks quickly and easily are also catered for by the new R Class as only Mercedes knows how: the four seats in the rear fold flat individually, allowing the load capacity to be expanded to as much as 2057 litres (VDA measuring method), a figure which clearly eclipses the load space offered by estate cars. Loading and unloading is particularly straightforward, courtesy of the level load floor measuring over 2.20 metres in length and the generously proportioned EASY PACK tailgate, which is available with remote-control opening and closing as an optional convenience enhancing feature.
Engine outputs range from 165 kW/224 hp up to 225 kW/306 hp, clearly signalling just what the new R Class is capable of in terms of dynamic performance and motoring enjoyment. The powerful V8 gasoline engine under the bonnet of the R 500 propels it from standstill to 100 km/h in just 6.9 seconds and on to a top speed of 240 km/h (provisional figures). Also to be found in the engine line up (from the beginning of 2006) is a new six cylinder power unit with third-generation common rail, direct injection technology. The V6 engine places its class beating peak torque of 510 Newton metres on tap from as low down as 1600 rpm. The fuel consumption figures returned by the R 320 CDI are no less astounding: 8.9 litres per 100 kilometres (combined consumption).
A seven speed automatic transmission, permanent all wheel drive, the electronically controlled 4ETS traction system and ESP® team up to offer peerless driving safety. These systems all make up part of the standard specification of the new R-Class, as does air suspension at the rear axle.
In addition, some of the very latest Mercedes safety innovations are available as optional extras: PRE SAFE®, the multi-award-winning anticipatory protection system, detects critical handling situations and immediately springs into action to prepare occupants and vehicle alike for an imminent collision. Precautions include pulling the driver's and front passenger's seat belts taut, adjusting the front passenger seat to the optimum position and automatically closing the sliding sunroof. Another Mercedes first for improving standards of occupant safety still further is the NECK PRO crash-responsive head restraints (optional).
Dynamic space: The new R-Class, the Grand Sports Tourer from Mercedes-Benz
New York, Mar 23, 2005
For the second time within the space of just one month, Mercedes-Benz is lifting the wraps on another brand new model series, the new R-Class, which is making its world debut at the New York International Auto Show.
This groundbreaking vehicle concept reaffirms the role of Mercedes-Benz as the visionary and trendsetter amongst automotive brands, since the R-Class founds a new and highly promising market segment. It takes the acknowledged strengths of established vehicle categories, such as sporty Saloon, Estate, MPV and SUV, and fuses them to create a new car with a character all of its own, a car that is all about the three Ds: Dimensions, Design and Dynamism. The new R-Class is being launched first in North America, in autumn 2005; deliveries to customers in Europe will begin at the beginning of 2006.
The novel concept of the Grand Sports Tourer caters to the needs of modern-minded people looking for a car that offers tremendous versatility combined with athletic performance. Quite apart from boasting ample spaciousness, exemplary standards of safety and impeccable comfort for up to six passengers, the new R-Class also enthrals with its beguiling styling, prestigious flair and, last but by no means least, its dynamism out on the road.
To put it in a nutshell: the Grand Sports Tourer offers a whole new motoring experience.
It was back in 2002 that Mercedes-Benz first unveiled this revolutionary new vehicle concept to the public; less than three years later the study has evolved to reach series-production status.
Measuring 5157 millimetres from nose to tail, the body of the new Mercedes-Benz R-Class is akin to a luxury saloon in size but is considerably more spacious inside. This is due primarily to the sophisticated vehicle concept and a dimensional design that has been ingeniously planned right down to the finest detail: around 64% of the vehicle's overall body length is available for the occupants, proportions that conventional notchback saloons are simply unable to match.
Dimensions: spacing between seats up to 990 millimetres
Consequently, standards of interior spaciousness and comfort are nothing less than first-class. Take the seat spacing, for instance, which amounts to 920 millimetres, while the second and third rows of seats can be separated by up to 840 millimetres. Moreover, the second-row seats can be adjusted individually fore and aft, thereby increasing the seat spacing to as much as 990 millimetres. The maximum distance between the second and third rows of seats (depending on seat position) is 920 millimetres.
Likewise, the figures for headroom (rear: up to 1027 millimetres) and shoulder room (front: 1530 millimetres; rear: up to 1514 millimetres) take the levels of space and comfort aboard the Mercedes-Benz R-Class into a new dimension.
Each of the vehicle's six passengers can sit back and relax in comfortable individual seats which offer the added luxury of armrests in the second row. The list of optional extras includes a centre console between the individual seats in the rear with extra stowage compartments along with large cup holders for holding both cups and bottles upright during the journey.
The separate DVD/CD player which is also available as an option gives passen-gers in the rear full control over their own in-car entertainment programme. Colour screens and earphone connections are integrated into the back of the head re-straints in front.
The efficient air conditioning system makes long journeys aboard the new R Class all the more comfortable. In addition to the standard-specification THERMATIC dual-zone climate control featuring a separate control panel for the passengers in the rear, Mercedes-Benz is also able to offer a newly developed multi-zone THER-MOTRONIC system as an option. Equipped with over a dozen sensors as well as an auxiliary booster blower, the system is able to faithfully maintain the temperatures set by the driver, the front passenger and the occupants in the rear. Climate control in the new R-Class is rounded off by a separate rear air conditioning unit which can be ordered as an option for the third row of seats.
The specially developed panoramic sunroof (optional), whose glass panels extend over virtually the entire surface of the roof, ensures a cooling supply of fresh air for the interior whilst letting in a pleasant amount of extra light, which all adds up to a matchless open-air motoring sensation for the occupants.
Families who are keen on sports and recreational activities and who are looking for a versatile car that can adapt to all manner of transportation tasks quickly and easily are also catered for by the new R-Class as only Mercedes knows how: the four seats in the rear fold flat individually, allowing the load capacity to be expanded to as much as 2057 litres (VDA measuring method), a figure which clearly eclipses the load space offered by estate cars. Loading and unloading is particularly straightforward, courtesy of the level load floor measuring over 2.20 metres in length and the generously proportioned EASY-PACK tailgate, which is available with remote-control opening and closing as an optional convenience-enhancing feature.
Design: a poised, assured presence
The design provides a visual expression of the poised, assured and dynamic character of the new R-Class. The front end is dominated by a striking radiator grille whose long, horizontal louvres symbolise strength and energy – attributes which characterise more than just the shape of the Grand Sports Tourer. The headlamps are equally expressive. Set well to the outside, they reinforce the powerful-looking, broad stance of the bodywork.
The arching roof line is a further typical styling element of the new R-Class, providing a sweeping link between the A-pillar and D-pillar and lending the car a sleek, coupé-like silhouette. The pronounced, muscular shoulders of the body add yet more dynamism to the Grand Sports Tourer and reveal its true nature.
Dynamism: V6 and V8 engines with up to 510 Newton metres of torque
Engine outputs range from 165 kW/224 hp up to 225 kW/306 hp, clearly signalling just what the new R-Class is capable of in terms of dynamic performance and motoring enjoyment. The powerful V8 powerplant under the bonnet of the R 500 propels it from standstill to 100 km/h in just 6.9 seconds and on to a top speed of 240 km/h (provisional figures).
Also to be found in the engine line-up is a new six-cylinder power unit with third-generation common-rail, direct-injection technology, whose credentials include improved fuel consumption, even lower exhaust emissions and an audible improvement in refinement. The V6 engine places its class-beating peak torque of 510 Newton metres on tap from as low down as 1600 rpm. The fuel consumption figures returned by the R 320 CDI are no less astounding: 8.9 litres per 100 kilometres (combined consumption).
Powered by the new 200-kW/272-hp V6 petrol engine, the R 350 accelerates from 0-100 km/h in just 8.3 seconds and goes on to reach a top speed of 230 km/h.
All engine models are partnered as standard by the 7G-TRONIC seven-speed automatic transmission, which itself comes with a noteworthy new feature in the form of DIRECT SELECT. This electronic transmission control system has allowed Mercedes engineers to dispense with the conventional automatic selector lever in the centre console and to replace it instead with a lever on the steering column. Additional gearshift buttons on the steering wheel enable drivers to manually pre-select the seven forwards gears, just like in a Formula One racing car. This allows the power reserves of the six and eight-cylinder engines to be harnessed to optimum effect in any driving situation.
Permanent all-wheel drive, the electronically controlled 4ETS traction system and ESP® team up to offer peerless driving safety and keep the new R-Class safely on course, even in very bad road conditions. These systems all make up part of the vehicle's standard specification, as does air suspension at the rear axle.
Mercedes customers also have the option of AIRMATIC all-round air suspension. This is interlinked with the ADS Adaptive Damping System, offering motorists the facility of raising the body by up to 50 millimetres when driving along rough roads. At high speeds above 120 km/h, the body is automatically lowered by 20 millimetres to reduce wind resistance.
Quite apart from making travelling in the Grand Sports Tourer an extremely comfortable experience, the very latest innovations from Mercedes also make it an ex-tremely safe one too: PRE-SAFE®, the multi-award-winning anticipatory protection system which is available as an option, detects critical handling situations and immediately springs into action to prepare occupants and vehicle alike for an imminent collision. Precautions include pulling the driver's and front passenger's seat belts taut, adjusting the front passenger seat to the optimum position and automatically closing the sliding sunroof. These preventive protection measures improve the seating position of the vehicle's occupants prior to impact, thereby enhancing the restraining effect of the seat belts and airbags.
Adaptive front airbags and front sidebags as well as windowbags can all be found on the standard specification list of the new R-Class, and all passengers enjoy the added reassurance of belt tensioners and belt force limiters. A further Mercedes first for improving standards of occupant safety still further is the NECK-PRO crash-responsive head restraints (optional): in the event of a collision from the rear, the head restraints instantly slide forwards by 44 millimetres and upwards by 30 millimetres. This has the effect of cushioning the front passengers' heads earlier, which reduces the risk of whiplash.
Mercedes-Benz offers a number of packages comprising valuable extras for the new R-Class. This allows customers to appoint and upgrade their Grand Sports Tourer to suit their personal taste. In addition to the AIRMATIC package, options include the chrome styling package for the exterior, a sports styling package featuring a specially styled instrument cluster, sports pedals, 19-inch wheels and power-adjustable sports seats upholstered in Alcantara/ARTICO man-made leather, as well as an interior appointments package comprising leather upholstery, power-adjustable front seats and wood trim.
Model range and equipment: entering a new dimension
* Unprecedented vehicle concept responds to new customer needs
* New dimensions for untrammelled enjoyment of space travel on wheels
* Fully equipped with air conditioning, radio and 7G-TRONIC
* Individual extras in package form
New York, Mar 23, 2005
There is never a shortage of new ideas. However, only a very few of them stand the test of time. Once the initial "wow" effect has subsided, one common stumbling block is the lack of market acceptance as it emerges that customers are actually looking for something completely different.
Whenever Mercedes-Benz devises new automotive concepts, the customers have already had their say. Product planners, designers and engineers discuss the concept with motorists, sound out their opinions and find out what expectations they would have of the car. This continuous dialogue reveals people's changing interests, ways of life and mobility requirements: in other words, it finds out what customers really want.
The revolutionary Sports Tourer concept is the end product of customer interviews held all over the world. It fits in perfectly with the notion of a car whose spaciousness, comfort and performance equip it to master any challenge and whose state-of-the-art innovations from all areas of automotive engineering blend together perfectly with a thrilling design.
Mercedes-Benz has put the ideas for such a trailblazing car into practice in the form of two separate model series: the B-Class, known as the Compact Sports Tourer, and the R-Class, which is premiering in New York under its title of Grand Sports Tourer.
What makes this new automotive design quite so fascinating is its versatility, uni-fying as it does the dynamism of a sporty saloon, the spaciousness and comfort of an MPV, the versatility of an estate and the poise and assurance of an off-roader. Combined with a host of new ideas, the result is a new vehicle type in its own right which knows no equal - the R-Class, the Grand Sports Tourer.
The three terms which describe the new Mercedes-Benz model leave no doubt as to where its main strengths lie:
* Grand refers to its size, space and practicality: with a body length of 5157 millimetres, the R-Class offers far more room than many saloon models in the luxury segment. This translates into a completely new motoring sensation for passengers: untrammelled enjoyment of "space travel" on wheels.
* Sports symbolises dynamism, high performance potential and a thrilling mo-toring experience: the two potent six-cylinder engines and the V8 power unit that are available for the R-Class span a power spectrum from 165 kW/ 224 hp up to 225 kW/306 hp. A seven-speed automatic transmission, permanent all-wheel drive, the 4ETS Electronic Traction System and ESP® all make up part of the standard package.
* Tourer is a reference to this innovative new car's outstanding credentials as a luxurious touring car: the new suspension system with standard-fitted air suspension at the rear, comfortable individual seats and automatic climate control gives it everything it needs for indulging its occupants with silky smooth comfort on long journeys.
Thanks to all of the above fortes, the Grand Sports Tourer neatly fits in with the current Zeitgeist, mirroring an attitude toward life that the young and the young-at-heart are keen to express through the medium of the vehicle they drive: being free and without ties, willing to take on any challenge and revelling in spontaneity. In practise, this means packing your bags on the spur of the moment, for example, setting off into the great outdoors with friends and enjoying the drive there together.

Design: The dream of space travel come true
* Design language full of agility, excitement and emotionality
* Striking sports car front and coupé-like lines
* Dashboard in the form of an athletic muscle
New York, Mar 23, 2005
A car with a length of around five metres which is able to offer first-class comfort for up to six passengers is very hard to overlook out on the road. Despite its generous dimensions, the Mercedes designers have successfully packaged the new R-Class in such a way that it appears both distinctively sporty and elegant - and therefore exudes agile light-footedness despite its size. In other words: it is a vehicle which makes the dream of space travel come true.
The design concept of the new R-Class is based on wide, sweeping proportions acting together with a long wheelbase and short overhangs. A prominent, arched roof line elegantly connects the A and D-pillars, making for an extended, coupé-like silhouette. The pronounced wedge-shape and muscular shoulders give the car additional dynamism and unmistakably assert its poised, assured character, producing an incomparable synthesis of generous interior space and sporty elegance.
A pronounced arrow-shape at the front of the new R-Class is a prominent feature. With a highly visible central ridge, this divides the bonnet area and continues down the radiator grille and into the centre section of the front bumper. In combination with the rising longitudinal lines it both communicates powerful forward motion and lends a lightweight impression to the front end.
The bonnet rises from the wings like a sculpture and reinforces the muscular presence of the front end. Markedly contoured surfaces, sharply defined edges and scalloped sides break up the basic lines, creating a three-dimensional effect and playing very effectively with light and shade. Flowing from the bonnet surface, the edges harmoniously blend into the A-pillars and combine the front end with the overall vehicle structure. A broad radiator grille dominates the typical Mercedes face of the new R-Class, creating a further sporty touch. It features three horizontal louvres of trapezoidal cross-section which are either painted silver or bear a chrome decorative strip, depending on the design and equipment line. The prominent radiator surround is another feature suggesting power and precision.
The bumper is very deep-drawn and visually lowers the centre of gravity – an effect reinforced by large air intakes in the bumper panelling. On the right and left these have silver frames housing the fog lamps, which resemble turbines and emphasise the width. A wing-like front spoiler defines the front end at the lower edge and gives the Grand Sports Tourer a four-square stance on the road surface. At the same time it reflects another interesting design theme of the R-Class, namely aerodynamics. The line drawn by the lower edge of the front spoiler is continued along the side skirts and extends into the rear end, where it ends in the rear diffuser surround as a counterpart to the front end.
The long, obliquely angled, elliptical headlamps lend this versatile and spacious vehicle its own identity. Arranged longitudinally, they visually shorten the length of the body and blend into the striking lines of the bonnet and wings. Additional side lights arranged inside complete this reinterpretation of the Mercedes look.
The crystal-clear headlamp lenses give a sense of lightness and brilliance, allowing a view of the powerful lighting technology of the new R-Class, which projects its beams onto the road from shining chrome cylinders.
The arched roof line is reminiscent of a coupé
The side view is heavily characterised by the arched roof line, which joins the A and D-pillars in a sweeping curve. It rises from the low line of the front end, long bonnet and swept-back windscreen and ends in the powerfully bulging tailgate. In this way the Mercedes designers have created a dramatically curving silhouette with flowing, coupé-like lines whose sporty elegance impresses despite the size of the car.
This is also assisted by the slight rearward rise of the lines in the flanks: from the front wheel arch to the rear lights, a pronounced shoulderline divides the side aspect and creates a refractive edge between the concave and convex surfaces of the doors. As this line rises slightly towards the rear, it also accentuates the wedge-shape of the body - and therefore the dynamic and powerful character of the R-Class. At the rear end this line blends directly into the tailgate, emphasising character and forward motion.
The extended window areas and high-gloss black door frames form a continuous surface and reinforce the impression of length. Depending on the design and equipment line, this is further underlined by chrome decorative trim around the entire window area and contrasted by mirrors painted in the vehicle colour. Dynamic length is also suggested by the D-pillar, which tapers at the lower end and is supported at the lowest point of the window line to suggest an urge to leap forward.
Large wings and pronounced wheel arches with continuous chamfers direct the eye to the 17 to 19-inch light-alloy wheels, depending on the line. Their design has strong yet sporty contours, in line with the sporty all-wheel-drive character of the new R-Class. The side skirts are equally striking; they have a pronounced flare and are of aerodynamic design, thereby contributing to good tyre-to-road adhesion. At the same time they form another interesting refractive edge.
The design of the heavily curved rear end also shares the dynamically flowing lines which join the front and sides. The shoulderline rising toward the rear surrounds the rear light clusters and transfers its expressiveness to the tailgate. The rear light clusters appear to grow organically from the shoulder muscle, extend forwards considerably and thereby appear to shorten the body overhang. They feature round sections containing the reversing lights and indicators which form a clever design counterpart to the cylinders of the headlamps.
The design idiom of the exterior is continued in the interior
The power-oriented design idiom of the body styling, which is mainly based on an interesting contrast between convex and concave surfaces, has also been adopted in the interior by the designers. A harmonious synthesis of high-quality materials finished with the great attention to detail typical of Mercedes ensures a definite atmosphere of wellbeing in the variable interior, which offers up to six occupants an outstanding level of travel comfort.
The upper section of the dashboard extends across the entire width of the car like a central muscle, expressing in visual terms the performance potential of the new R-Class to the driver and passengers. This strong transverse emphasis is taken up again in the sporty four-spoke steering wheel with aluminium inserts in the lower two spokes, and is further emphasised by wood or chrome trim and a two-tone interior colour scheme. While the upper section of the dashboard, the soft armrests on the doors and the seat surfaces are in a dark colour tone, the remaining parts of the interior create an interesting contrast with a lighter variant of the same colour.
The driver’s eye falls on a sporty instrument cluster with large, round dials reminiscent of a high-quality chronograph, which is housed in slanted tubular binnacles to prevent reflections and ensure optimal legibility under all lighting conditions. The instruments feature fine chrome surrounds. Between them there is a two-section multifunction display – right in the driver’s field of vision.
Thanks to the high-tech DIRECT SELECT transmission control system, the automatic transmission can be operated by nudging the lever on the steering column; this layout also for the first time makes a complete redesign of the tunnel covering possible. In place of a selector lever this now has sufficient space for lidded stowage compartments and a large cup holder.
Hand-finished materials such as wood, leather and aluminium please both the eye and the fingertips. Attention to detail and painstaking precision are to be found everywhere in the luxurious interior of the new R-Class.
nterior and comfort: A moving experience of inner freedom
* Generous levels of spaciousness and first-class comfort for 4+2 passengers
* Benchmark figures for seat spacing, headroom and shoulder room
* Luggage capacity of up to 2057 litres
* THERMATIC as standard, multi-zone THERMOTRONIC as on option
* DVD entertainment system for passengers in the rear
New York, Mar 23, 2005
Modern-minded people want plenty of space, effortless motoring, an extremely high degree of flexibility and the ability to use it whenever they feel like it - and the Grand Sports Tourer comes closer than any other vehicle to offering them exactly what they are looking for. Anyone seated in one of the luxurious individual seats is immediately treated to a memorable experience: an untrammelled experience of "space travel" on wheels.
This new standard in travel does not just stem from the "XXL" dimensions of the interior. The R-Class offers far more besides, courtesy of a harmonious blend of factors that produce an uplifting sense of wellbeing: the smooth-running V6 or V8 engines, the flawless climate control, the pleasant acoustics, the air-sprung chassis, the appealing colour scheme, the high-grade materials - just a few of the features which combine to make travelling aboard the R-Class an unforgettable experience.
The challenge faced by engineers at Mercedes as they strove to create a vehicle concept that genuinely broke new ground started as early as the dimensional concept stage. The overriding question here was "How much car do six passengers need to enjoy Mercedes-class travel?". The answer was a car with a two-box design measuring 5157 millimetres from front to rear. This makes the R Class akin to a luxury saloon in size but considerably more spacious inside. Around 64% of its body length is dedicated to the occupants, a proportion that conventional body concepts are simply unable to match.
This exemplary economy of space maximises freedom of movement, at the same time forming a linchpin of the vehicle's supreme long-distance comfort. Several of the interior measurements simply speak for themselves. The seat spacing, one of the key indicators of freedom of movement and interior comfort, measures 920 millimetres between the first and second rows of seats in the standard position, a figure that is normally only associated with luxury saloons. Between the second and third seat rows, up to 840 millimetres are available. Since the second-row seats are adjustable longitudinally, rear-seat passengers can enhance their own feeling of comfort still more, increasing the seat spacing between the first and sec-ond rows to 990 millimetres.
Headroom is another discipline in which the Grand Sports Tourer excels, with 1027 millimetres available in the second row and 946 millimetres in the rearmost row of seats. The width measurements inside the R-Class also open up a whole new dimension in space and comfort. At 1550 millimetres in the front and 1562 millimetres in the rear, elbow width, for example, eclipses the figures for other luxury saloons by as much as 100 millimetres, representing a formidable result for the new vehicle concept.
Versatility is also high on the new model's list of specialities: the individual seats in each of the rear rows can be folded flat separately as required, while the op-tional centre console can be removed completely, all in just a few simple steps. Thus equipped, the interior is able to mould itself to changing space requirements or to the transportation task in hand, making light work of carrying mountain bikes, skis, snowboards or any other recreational equipment items, for example. Even with a full contingent of six passengers on board, the R-Class still has enough space for a large golf bag behind the third row of seats.
With the rear seats folded down, the level load surface extends over a distance of 2217 millimetres measured from the front seat backrests to the tailgate. The vehicle's load capacity as measured using the VDA method also comfortably outstrips the figures for large estate cars, with a maximum of 2057 litres when loaded up to roof height (in accordance with the VDA measuring method). Folding down just the third row of seats produces a luggage compartment with a maximum capacity of 977 litres. The seats can be rearranged to suit the current transportation task in just a few quick steps:
* The head restraints in the second row of seats are first pulled out and placed on the seat cushions. Then, the backrests are tilted forwards and the entire seat unit is pushed downwards.
* In the case of the third row of seats, the seat cushions are first raised to a vertical position, allowing the backrests to be folded forwards. The seat cush-ions can then be folded further forwards into a horizontal position. It is there-fore the reverse faces of the two rear rows of seats which together form the level load compartment floor.
The driver's and front passenger seats both feature power controls for adjusting the height, seat cushion inclination and backrest angle. Their fore-aft adjustment range is 294 millimetres, allowing drivers of all statures to make themselves completely comfortable. The standard-fit facility for adjusting the steering wheel's height and reach serves to make doubly sure that all drivers are able to find the sitting position that is best suited to them. The individual seats in the second row can also be manually repositioned fore and aft through a range of 150 millimetres, while the seats' EASY ENTRY function makes it simpler for passengers in the rearmost row of seats to get into and out of the vehicle.
Anyone looking to customise seating comfort yet further is able to select from the following Mercedes-Benz optional extras ...
* Electrically adjustable front seats with memory function for storing the seat, head restraint, exterior mirror and steering wheel settings
* Electrically adjustable sports seats with raised backrest bolster cushions and Alcantara/TWIN Leather upholstery for both driver and front passenger;
* Multicontour seats with inflatable air cushions and TWIN Leather upholstery for both driver and front passenger.
Forms, materials and ergonomics form a harmonious whole
It is not only the seating comfort in the R-Class that makes it such a pleasure to travel in, a host of further characteristics play a contributory role too, notably its aesthetic, tactile and ergonomic qualities.
The powerful design idiom of the body's exterior, which stems predominantly from the striking contrast between its convex and concave-shaped surfaces, continues through into the interior of the vehicle. The top section of the dashboard cuts a muscular line from one side of the vehicle right through to the other, signalling power and performance capability as it does so. The two-tone interior colour scheme lends further emphasis to the pronounced crossways effect: the dark tone used for the dashboard, armrest and door panels forms an appealing contrast with the lighter tone variant sported by the remaining interior components. The tactile qualities are every bit as impressive too, thanks to the use of high-grade materials such as the fine leather on the armrests, the soft plastic surface of the dashboard, the aluminium or fine-wood trim and the switches in the centre console, whose faces gleam with a special "soft-touch" coating that has a particularly pleasant feel.
One of the most eye-catching features is the instrument cluster, whose large, round dials protrude from circular cylinders that are angled slightly inwards, while the black faces are a nostalgic touch that recalls the design of classic, high-precision chronographs. The left-hand cylinder houses the speedometer and clock, whilst the cylinder on the right keeps the driver informed of rev speed and fuel level. The various red and yellow indicator lamps that are distributed over the surface of the two dials only ever make their presence known when the engine is started or they are prompted to light up.
Nestling in-between the two dials is a split central display, showing the distance travelled at the top and the current drive mode, selector lever position and outside temperature at the bottom. At the press of a thumb, the buttons in the standard-fit multifunction steering wheel give drivers control over the stereo system and car phone, as well as allowing them to call up important information, which again appears in the instrument cluster's central display. This also provides a convenient means of programming individual settings, covering everything from the digital km/h display and activation of the automatic central locking to setting the speed limit for winter tyres. Once these settings have been made, they remain permanently activated and require no further intervention on the part of the driver.
The Mercedes engineers have made the interior door trim an integral part of the operating concept, too, incorporating into it the controls for the standard-specification power windows, the exterior mirror adjustment and the remote tail-gate release (driver's door).
The units and controls in the centre console are arranged in accordance with ergonomic principles, with the relative importance of the functions, the frequency with which they are used and visual considerations taking priority. Consequently, the car stereo system or navigation system, depending on the model's specifica-tion, is located in the topmost position, where it is within easy reach of the driver. Below this can be found the control panel for either the THERMATIC automatic climate control system that is fitted as standard or for the optional multi-zone THERMOTRONIC system, with both units featuring ergonomic, attractively styled rotary controls for manually adjusting the temperature (right). Rounding off the centre console at the bottom is an array of buttons for controlling various functions.
Dispensing with a conventional automatic transmission selector lever in favour of the brand new DIRECT SELECT gearshift on the steering column has made way for a roomy stowage compartment and a cup holder in the transmission tunnel covering of the R-Class. Both are concealed beneath covers which gently open when light pressure is applied. The padded armrest between the front seats also conceals a spacious stowage compartment, with a special section at the top where a mobile phone can be installed. The back of the transmission tunnel covering features two individually adjustable air outlets for the rear compartment.
Audio 20 car radio system with CD player fitted as standard
The Grand Sports Tourer rolls off the production line equipped with the Audio 20 stereo system as standard, ensuring excellent in-car entertainment and pure musical listening pleasure. It features an FM/MW/LW/SW tuner combined with an integral CD player. The unit also boasts a keypad which can be used to enter phone numbers when it is networked with a car phone or mobile phone.
There is a choice of two optional combined tuner and navigation systems for the new R-Class:
* The Audio 50 APS unit comprises a twin FM tuner, CD player, TFT colour display and arrow-directed navigation. The integrated CD player can continue to play audio CDs whilst navigation is in progress. All other radio and control functions are identical to the Audio 20 unit.
* The hallmark feature of the COMAND APS system is its large 6.5" colour display featuring state-of-the-art TFT technology. A full-colour map assists with route guidance. Once the route has been computed, the navigation DVD can be removed to allow audio CDs to be played, in which case the navigation system will issue its instructions in the form of arrows. Radio reception is taken care of by a twin FM RDS tuner which is also able to receive LW, MW and SW stations.
All of the Mercedes car radio systems include a speed-sensitive volume control: above a speed of around 20 km/h, the volume is raised in increments to compensate for the increase in background noise. An antenna diversity function, which ensures optimum reception by selecting the strongest signal from the roof aerial and the two FM aerials in the rear window, also makes up part of the standard package.
Sound system and DVD system for superlative in-car entertainment
The Mercedes car stereo systems channel their output through a total of eight speakers as standard. An even more sophisticated set-up is available in the form of a surround sound system boasting eleven speakers in all, plus an extra sub-woofer. The system has been custom-designed to suit the interior's acoustics: a microphone monitors current noise levels, enabling a microcomputer to adapt the volume and sound accordingly to ensure uninterrupted high-fidelity listening.
A six-disc, MP3-compatible CD changer which is housed in the glove compartment may also be specified as an option in conjunction with the Audio 20, Audio 50 APS and COMAND APS systems.
A further equipment option allows passengers in the rear to enjoy the freedom of compiling their own audio or video entertainment programme. The Rear-Seat Entertainment package comprises two colour screens with earphone connections which are incorporated into the backs of the front-seat head restraints, along with a CD/DVD player which is accommodated in the rear centre console. There is also a facility for connecting external audio/video devices or a games console.
Choice of two sensor-regulated air conditioning systems
Climate control for such a spacious interior as that in the R-Class is reliant on powerful technology. Mercedes engineers have devised two different systems which are designed to offer supreme passenger comfort:
* In standard specification, the R-Class comes equipped with the THERMATIC system that provides dual-zone interior climate control.
* Customers may also opt for the multi-zone THERMOTRONIC system which permits individual temperature settings to be made for three separate zones: for the driver's side, for the front passenger side and for the passengers in the second row of seats in the rear.
The multi-zone THERMOTRONIC system can in turn be expanded by the addition of a rear air conditioning unit for the third row of seats. This unit is concealed in the rear behind the left-hand sidewall panelling.
Both systems have been adapted to take account of the generous interior dimensions of the new R-Class, resulting in exemplary efficiency. They are equally as capable of cooling down the interior quickly on hot summer days as they are of keeping passengers snug and warm in the depths of winter. The automatic climate control's maximum heating capacity, for example, as measured in accordance with test specifications in ambient air that has been cooled down to minus 20 degrees Celsius and at a coolant temperature of 80 degrees Celsius, is ten kilowatts. To put this figure in perspective, it roughly equates to the capacity of a modern central heating system in a detached house.
On the R 320 CDI diesel-powered model, the effect of the heater core is boosted at low outside temperatures by an electrical PTC (Positive Temperature Coefficient) heating element with a heating capacity of 1.7 kilowatts. The PTC's additional heating power is required as a result of the six-cylinder CDI engine's outstanding thermal efficiency, which has an extremely positive impact on fuel consumption but results in far less heat being dissipated to the coolant at partial throttle than is the case with many other engines.
Sensors regulate operation of the THERMATIC automatic climate control system to take account of temperature changes and levels of direct sunlight. The system is controlled by a network of nine sensors in all: seven outflow pickups in the air outlets monitor the temperature of the air as it enters the interior, one sensor in the control panel records the interior temperature and a solar sensor on the dashboard relays data on the intensity of the sunlight and its angle of incidence. This provides all the information that is required to compare the passengers' desired settings with the actual readings and adjust climate control accordingly. This means that in automatic mode, the temperature, blower speed and air distribution are permanently regulated in such a way that the temperatures set by the driver and front passenger are faithfully maintained once they have been reached. At high ambient temperatures, for example, the automatic climate control is also capable of varying the proportion of recirculated air: this has the dual effect of cooling down the passenger compartment more rapidly and of minimising the re-quired cooling output.
To keep THERMATIC running as economically as possible by adapting its operation to current requirements, the powerful air conditioning compressor is able to adjust its output smoothly. This is done by means of a solenoid valve which varies the compressor's swept volume.
The driver and front passenger are each able to select their preferred temperature using stylish rotary controls. Red LEDs indicate the temperature settings. The right-hand control also includes buttons for activating the rear compartment ventilation and residual engine heat utilisation functions. In the centre of the panel between the two temperature controls can be found buttons for manually setting the blower speed, switching on the defrost function, the heated rear windscreen and air recirculation mode, as well as for altering the air distribution settings.
Passengers seated in the second row benefit from their own control panel. Located on the rear of the transmission tunnel, it allows air distribution to be adjusted individually for each of the second row seats.
Multi-zone THERMOTRONIC with booster blower for the rear
The optional multi-zone THERMOTRONIC system offers an even higher standard of climate comfort, which is especially of benefit to passengers in the rear. To achieve this, Mercedes-Benz devised the principle of three-zone climate control, whereby the occupants in the second row of seats are able to select their own temperature, airflow and air distribution settings independently of the driver and front passenger. This is all made possible by the inclusion of an auxiliary booster blower in the transmission tunnel covering, which permits virtually autonomous control over the airflow in the rear.
A team of eleven probes keep the multi-zone THERMOTRONIC system's micro-computer fed with up-to-the-minute readings: the seven outflow temperature pickups in the air outlets, the central temperature sensor in the control panel and the solar sensor are joined by a dew-point sensor whose air humidity readings are also used to automatically regulate climate control. Finally, the multi-zone THER-MOTRONIC system in the new R-Class also comes equipped with a pollutant sensor which monitors levels of carbon monoxide and nitrogen oxides in the outside air. If the concentration of pollutants becomes too high, the air conditioning automatically switches over into air recirculation mode. In the system's fresh air mode, an activated charcoal filter works to absorb pollutants and reduce the intensity of any unpleasant odours penetrating the passenger compartment.
LEDs in the stylish rotary controls on the front of the multi-zone THERMOTRONIC control panel keep the driver and front passenger informed of the current temperature settings. The "Mono" button in the left-hand control enables the settings for both the driver's and front passenger side, as well as for the rear, to be synchronised and temperature selection to be controlled centrally using the left-hand rotary control.
Computational thermal and flow models had a key role to play during the development of this highly complex and efficient system. With the aid of these models, the engineers at Mercedes were able to investigate the effectiveness of a number of ideas and to optimise the concepts long before initial prototype testing was carried out. The question of how large to make the air outlets and where to best posi-tion them formed a focal point of the development work. The end result is a bat-tery of up to 18 air outlets, which are incorporated into the dashboard, the foot-well, the transmission covering and the B-pillars. Electric motors in the interior of the air conditioning unit regulate the airflow based on either the manual settings or - in automatic mode - based on a computer program.
Apart from the large defroster outlet directed towards the front windscreen, four further air outlets have been stylishly integrated into the dashboard which the driver and front passenger can adjust individually; they have a swivelling design and include thumbwheels for reducing the airflow as required. A floor-level outlet together with two swivelling and adjustable outlets in the transmission tunnel take care of supplying air to the rear. Additional swivelling air outlets which are directed towards the rear passenger compartment are incorporated into the inte-rior B-pillar trim on R Class models which leave the factory equipped with multi-zone THERMOTRONIC.
Body and safety: Safe and secure
* Body structure with crash boxes and large safety zones
* Belt buckle tensioners and belt force limiters for all occupants
* PRE-SAFE® and crash-responsive NECK-PRO head restraints on request
* Unique panoramic sliding roof with two large areas of glass
New York, Mar 23, 2005
Passive safety, long-term durability, comfort, lightweight construction – to meet these and other stringent Mercedes requirements the engineers in Sindelfingen developed a unitised bodyshell structure of which half comprises high-strength and very-high-strength steel alloys. These absorb severe forces during an impact and offer outstanding torsional rigidity. Accordingly the bodyshell provides an important basis for handling safety, ride comfort and dynamic performance.
Moreover, the latest production and design processes ensure the long-term quality which is so typical of a Mercedes bodyshell. One example is the low-stress joining technology: the flanges at the edges of the steel body components are designed so that any tolerances are compensated when the steel sheets are positioned, enabling them to be welded together with minimal internal stresses. This process improves the dimensional accuracy of the bodyshell.
Mercedes-Benz also uses fully-galvanised panels in all areas of the bodyshell, some of which have an additional organic coating depending on their location. This coating also contains rust-inhibiting zinc pigments. Highly vulnerable areas of the body are additionally protected with a cavity-fill preserving agent, and the welding flanges are carefully weather-sealed. Using plastic for a large area of the multi-part underbody panelling, which protects against stone chippings, water and soiling, has allowed Mercedes engineers to dispense with conventional PVC underseal.
And finally the new R-Class also shines with an innovative, more scratch-resistant clearcoat employing on nano-technology, with which Mercedes-Benz has achieved significant progress with respect to long-term quality and value retention. This innovative paint system is used as standard for metallic and non-metallic finishes.
Front and rear-end modules can be replaced without welding
Ease of repair was another Mercedes requirement during bodyshell development, and the tried-and-tested modular concept made an important contribution in this respect: the front and rear-end modules are bolted to the body structure, and can therefore be replaced without troublesome welding work during accident repairs.
The front-end module basically consists of a robust aluminium cross-member which is not only used to attach the front bumper, but also has a major task during an offset frontal collision in directing impact energy to the unaffected side of the vehicle, where it is dissipated.
Two crash boxes of high-strength steel are connected to the front longitudinal members and together with the aluminium flexural member, absorb a large proportion of the impact energy during frontal collisions up to 15 km/h. The downstream structure remains unaffected by the crash as a result. The highly resistant longitudinal members are only activated at high impact speeds (more than 15 km/h) to provide a crumple zone. During an offset crash the second level of longitudinal members above the wheel arches forms an additional energy-absorption path. The integral member of high-strength steel to which the front axle, steering gear, engine and front axle differential are attached likewise deforms during a severe frontal collision and absorbs crash energy.
The main floor consists of three assemblies which form a robust structure in combination with additional cross-members. The centre floor area is designed as a tunnel which forms the backbone of the main floor, and therefore of the entire body structure. The two outer assemblies in the floor are reinforced with cross-members which both provide a solid base for the seats and also ensure a high level of transverse strength, which particularly benefits occupant protection during a lateral collision. In addition, a diagonal member extending from the firewall to the area of the B-pillar strengthens the main floor.
In conjunction with the floor panels the pillars, side members and sidewalls make up a highly robust safety zone for the vehicle occupants. The sidewall structure is of three-layered construction; in the interests of occupant safety the nodal points between the pillars, roof frame and side members are specially reinforced. The three-skinned A-pillars are supported by cross-members at several levels.
Crash boxes and strong sections absorb energy during a rear-end impact
As at the front end, easily repaired steel crash boxes and an aluminium flexural member are used at the rear end. These components absorb energy in the event of minor collisions with impact speeds up to 15 km/h, so that the downstream body structure remains undamaged. Bolted connections allow the inexpensive replacement of damaged crash boxes and the cross-member. The rear box-section side members of the new R-Class are designed as continuous, closed sections with gradually diminishing material thicknesses, and contribute substantially to occupant safety during a rear-end collision. The spare wheel recess is of steel, while the fuel tank is located in front of the rear axle where it is protected from impacts.
Airbags and belt force limiters work adaptively according to accident severity
With two-stage front airbags and belt force limiters (front), belt-buckle and inertia-reel tensioners, as well as sidebags and windowbags, the R-Class also meets the high Mercedes standard where occupant protection systems are concerned.
The sensors for the restraint systems include two up-front sensors on the front module whose remote positioning in the front end of the body enables them to detect the severity of a collision even earlier and with greater accuracy than the central crash sensor on the centre tunnel. This makes it possible to shorten the time that elapses between the moment of impact and the deployment of the airbags and belt tensioners even further. Moreover, these sophisticated sensors make it possible to control the pyrotechnical belt force limiters on the front seats adaptively, and to deploy the airbags in two stages depending on the accident situation. During a minor frontal impact the electronic control unit only ignites one stage of the two-stage airbag gas generators, and the airbag inflates more gently. Should the control unit detect a severe frontal collision, however, it deploys the second stage of the gas generator after a slight delay. As a result, the airbags are inflated to the maximum to provide the occupants with the level of protection required in a collision of this severity.
The belt force limiters for the driver and front passenger are also adaptive, i.e. they operate according to the accident situation: if the sensors send information that a frontal collision is severe, the seat belts are tensioned and reach their maximum retaining power. Shortly afterwards the force limiters switch to a lower level of force, which slackens the belts slightly and allows the front occupants to sink more deeply into the airbags. This reduces the loads acting on the chest area.
Crash-responsive head restraints reduce the risk of whiplash injuries
Newly developed NECK-PRO head restraints (optional) optimise protection for the driver and front passenger during a rear-end collision. They are likewise linked to the control unit: if the sensor system detects a rear-end collision with a defined impact severity, it releases pre-tensioned springs inside the head restraints which immediately cause these to move forward by about 44 millimetres and upwards by 30 millimetres. This means that the heads of the front occupants are supported at an early stage, reducing the risk of whiplash injuries. After NECK-PRO activation the head restraints can be unlocked and returned to their original position using a tool supplied with the car.
Sidebags and windowbags with complementary protective functions
With standard-fitted sidebags for the driver and front passenger, as well as windowbags, the restraint system of the new R-Class provides two further, highly-effective systems whose protective effect is complementary: while the sidebags primarily reduce the loads acting on the chest area, the windowbags provide head protection over a wide area for both front and rear occupants. During a lateral impact the windowbag inflates and extends from the front to the rear roof pillar like a large curtain. Accordingly it also gives protection against objects which might penetrate into the vehicle interior during a crash.
A special sensor system is responsible for deployment of the sidebags within milliseconds: in addition to the central sensor in the interior, satellite sensors located near the base of each B-pillar provide information about the severity of a lateral collision. The sophisticated crash sensor system in the new R-Class is rounded off by a roll-over sensor which activates the belt tensioners and windowbags in the appropriate situation.
PRE-SAFE® gives the R-Class "reflexes" which respond before an impending accident
Mercedes-Benz has also achieved a remarkable advance in the field of safety with the anticipatory occupant protection system PRE-SAFE®, which already becomes active during the seconds preceding an impending accident. PRE-SAFE® is available as an option for the new R-Class. The system creates the link between active and passive safety. It is networked with Brake Assist and the Electronic Stability Program (ESP®) and recognises critical handling situations which might lead to an accident. PRE-SAFE® intervenes in such dangerous situations within milliseconds, preparing both the occupants and the vehicle for the possible collision:
* The seat belts of the driver and front passenger are tensioned as a precaution.
* If the electrically adjustable front passenger seat with memory function (optional) is adjusted to an unfavourable fore-aft setting or cushion/backrest angle, it is moved to a better position.
* The sunroof is closed if there is a risk of the vehicle rolling over.
Thanks to these precautionary PRE-SAFE® measures the vehicle occupants are in a better seating position even before the accident occurs, enabling the seat belts and airbags to work more efficiently. If the accident is avoided, the preventive tensioning of the seat belt is automatically relaxed and the passengers are a
