Mercedes-Benz F-Cell Roadster Concept

Mercedes-Benz F-Cell Roadster Concept

The unique Mercedes-Benz F-Cell Roadster project bridging various fields of profession, the trainees of Daimler AG at the Sindelfingen Mercedes-Benz plant have built a Roadster with fuel cell drive.
For about a year, more than 150 trainees and dual education system students worked on the overall concept, development, assembly, and completion of the Mercedes-Benz F-Cell Roadster Concept.

The project involved junior employees from the fields of automotive mechatronics, model-building, electronics, coating technology, manufacturing mechanics, product design, and interior appointments. The prime objective of the project was to integrate the topic of alternative drive systems into training with hands-on experience.

Tradition meets the future

The Mercedes-Benz F-Cell Roadster Concept uniquely combines state-of-the-art technologies with the history of vehicle construction. As an allusion to the Benz Patent Motor Car from 1886, the vehicle is fitted with large spoked wheels. Moreover, the Mercedes-Benz F-Cell Roadster incorporates stylistic elements from diverse eras of automotive history, such as the carbon-fiber bucket seats with hand-stitched leather covers and the distinctively styled fiberglass front section, based on the component from the Formula One racing bolides.


The Mercedes-Benz F-Cell Roadster Concept is controlled with drive-by-wire technology, and a joystick takes the place of a conventional steering wheel. The vehicle is powered by the emission-free fuel cell system located at the rear. With a power rating of 1.2 kW the Mercedes-Benz F-Cell Roadster reaches a top speed of 25 km/h and has an operating range of up to 350 km.

Mercedes-Benz SLR Stirling Moss

Mercedes-Benz SLR Stirling Moss

With the SLR Stirling Moss Mercedes-Benz and McLaren are adding the crowning glory to the model family of their highly successful SLR super sports car with a new, uncompromisingly spectacular car. There is neither a roof nor a windscreen to separate the driver and passenger from the outside world; they enjoy unadulterated high-speed excitement with all the attributes of a speedster.

The new Mercedes-Benz SLR Stirling Moss is also characterised by the most sophisticated technology and a breathtaking design which reinterprets the SLR legend. With 478 kW/650 hp the SLR Stirling Moss accelerates its V8 supercharged engine from standstill to 100 km/h in less than 3.5 seconds, and has a top speed of 350 km/h - no other series-production car is at the same time so open and so fast. This extreme concept makes the new high-performance sports car a legitimate bearer of the name of the British motor racing legend and Mille Miglia record-holder Stirling Moss, who drove the legendary Mercedes-Benz SLR racing cars from victory to victory during the 1950s.

The exclusive Mercedes-Benz SLR Stirling Moss rounds off the current SLR family and is limited to 75 units. It is priced at 750,000 euros. The SLR Roadster will cease to be manufactured at the end of May 2009 as planned, and production of the Mercedes-Benz SLR Stirling Moss will commence in June 2009.

Three letters are all it takes to make car fans' hearts beat faster: SLR. In the 1950s the Mercedes-Benz SLR 300 celebrated victory after victory. It won the Mille Miglia and the Targa Florio as well as the Tourist Trophy. It was driven by the stars of the time: Juan Manual Fangio and Karl Kling - and, first and foremost, by the British racing driver Stirling Moss. At ten hours, seven minutes and 48 seconds he still holds the Mille Miglia record.


This is why the modern-day version of the legendary SLR carries the additional words "Stirling Moss" in its name. As the new Mercedes-Benz SLR Stirling Moss unites the character of the current SLR models with the fascination of the SLR of 1955. The core values of both the historical and the present-day SLR models include an exciting new design, innovative technology, high-class materials displaying perfect craftsmanship, and, above all: a unique driving experience for all the senses.

Whilst the 300 SLR earned its spurs on racing circuits the world over, the new member of the SLR family is not designed for the racetrack. Although it sets new standards in terms of technology, performance and excitement - just like its forebears - it is aimed at individuals who have exquisite requirements and nurture very special dreams.

Highly puristic concept without a roof or a windscreen
Remaining totally true to the specifications of the 300 SLR, the new Silver Arrow's equipment is extremely sophisticated and yet at the same time decidedly spartan, doing without both a roof and side windows. There are just two wind deflectors a couple of centimetres in height to protect the driver and passenger from the airflow. Two air scoops integrated into the bodywork serve as roll-over bars. With this extreme concept the new Mercedes-Benz SLR Stirling Moss is visually very different from all the other vehicles which belong to the elite sports car class.

The SLR Stirling Moss dazzles with its superlative performance. Accelerating from zero to 100 km/h in less than 3.5 seconds and with a top speed of 350 km/h this puristic high-performance sports car denotes completely new dimensions in open-top driving. And not just because of the impressive performance figures; every time drivers take to the wheel of the Mercedes-Benz SLR Stirling Moss their senses are addressed with a previously unheard of intensity, conveying a driving experience in its purest and most sensual form. This automotive thoroughbred thus facilitates the kind of open-air feeling that is utterly unique for a road-going vehicle.


Exciting design reminiscent of the SLR racing cars
The Mercedes-Benz SLR Stirling Moss, its entire bodywork made of fine lightweight carbon fibre, represents a stand-alone design concept. Whilst the Mercedes-Benz designers were working on the body of the new SLR Stirling Moss, they were fully aware every single moment that they were creating a vehicle with a top speed of 350 km/h. At the same time this supreme athlete is highly reminiscent of the SLR racing cars from the 1950s, whose design idiom still never fails to impress to this day.

The Mercedes-Benz SLR Stirling Moss sports an exciting, pronounced arrow-shaped form and is characterised by an elongated bonnet and a compact, muscular rear. As there is no windscreen, the exterior and interior flow smoothly into one. The bonnet also stretches from its striking tip right down into the interior, giving the vehicle body a distinctly sleek air. Even when standing still, the sports car radiates such dynamism that the observer immediately falls under its spell.
Further eye-catching features include two air scoops behind the driver and passenger. They carry additional roll-over bars, also uniting the traditional and the modern. The wings are powerfully contoured. Black-painted ventilation "gills" sitting facet-like on the sides and on the bonnet also cite the legend. A thrilling interplay of light and shadow ensues through the expressive lines, underlining the dynamic overall impression.

The vehicle can be closed by two tonneau covers which are carried in the boot. When both tonneau covers and the doors are closed the Mercedes-Benz SLR Stirling Moss resembles a sculpture.
In keeping with the puristic exterior of the vehicle, the interior is also reduced to the bare essentials. Surfaces penetrating each other in the instrument panel and doors make for an exciting atmosphere and resonate perfectionism. A mixture of high-class authentic materials such as carbon fibre, aluminium and fine-quality leather sets the style here. An aluminium plate carries the engraved signature of Stirling Moss and covers the area around the shift lever.

The innovative technology and polished aerodynamic concept
Developers working on the Stirling Moss were able to fall back on a wealth of experience gathered when producing the SLR Coupé and Roadster, in particular where the technical base was concerned, with its extravagant carbon-fibre design, high-performance suspension and throaty V8 engine. The common denominator uniting the Stirling Moss with the other members of the SLR family is the aerodynamic concept with a closed underbody and a diffuser in the rear bumper for maximum possible downforce at the rear axle - with one difference: the diffuser here is considerably larger than that on the coupé and roadster.
Thanks to the high-precision work carried out in the wind tunnel, the Mercedes-Benz SLR Stirling Moss always generates sufficient downforce for extremely safe handling. But the driver can also manually operate the AirBrake in order to increase the contact pressure further, during particularly sporty driving, for example. The AirBrake is also raised during powerful braking at speeds above 120 km/h, so as to stabilise the vehicle even more in such situations, thus facilitating maximum possible deceleration.

Limited to 75 units - the SLR models' crowning glory
The new Mercedes-Benz SLR Stirling Moss is the kind of high-calibre speedster coveted by the sporting gentry and enthusiasts alike. At the same time it is a collector's item which marks the pinnacle of an era and, for the foreseeable future, at least, the final curtain for the SLR. In May 2009 production of the SLR models will cease; only a total of 75 units of the Stirling Moss will be manufactured between June and December 2009, bearing chassis numbers from 1 to 75. Not only does this exclusive vehicle represent the conclusion of the current SLR family; it also serves as a very special thank you to the most loyal of SLR customers, for they are the only ones able to acquire a Stirling Moss.

Mercedes-Benz BlueZero Concept

Mercedes-Benz BlueZero Concept

Mercedes-Benz, is Based on a single vehicle architecture, this intelligent, modular concept allows three models with different drive configurations, all of which are able to meet customer requirements in terms of sustainable mobility:

* the BlueZero E-CELL with battery-electric drive and a range of up to 200 kilometres using electric drive alone
* the BlueZero F-CELL (fuel cell) with a range of well over 400 kilometres using electric drive
* the BlueZero E-CELL PLUS with electric drive and additional internal combustion engine as power generator (range extender). This version has an overall range of up to 600 kilometres and can cover a distance of up to 100 kilometres using electric drive alone.

The three Mercedes-Benz BlueZero variants are based on the unique sandwich-floor architecture which Mercedes-Benz introduced some ten years ago, initially for the A-Class and then for the B-Class, one of the aims being to integrate alternative drive systems. Advantages of the modified construction include the positive effect of the major drive components on the centre of gravity, their space-saving design and the fact that they are extremely well protected within the vehicle underbody. The five-seater Mercedes-Benz BlueZero concept cars also set standards in terms of lightweight design, interior layout and body form.

The BlueZero principle: flexible design, compact exterior, generously sized interior
All three BlueZero variants share the same key technical components, while the design and vehicle dimensions are identical. Measuring just 4.22 metres in length, the BlueZero models combine compact exterior dimensions with a generously proportioned and variable interior and luggage compartment. Five fully-fledged seats, a payload of around 450 kilograms and a luggage compartment capacity of over 500 litres make for outstanding everyday practicality. Thanks to their sandwich construction with a raised sitting position, the cars also offer an exceptionally high level of crash safety for the passengers and the technology, not to mention excellent all-round visibility.

Compared to electric cars based on conventional vehicle platforms and originally only designed for use in combination with internal combustion engines, Mercedes-Benz BlueZero Concept offers the following conclusive advantages:
* Interior space is retained in full. As the energy accumulators/generators are integrated into the spacious sandwich floor, no compromises are necessary when it comes to passenger space, luggage capacity or variability.
* The powertrain technology built into the sandwich floor ensures a low centre of gravity and, consequently, extremely reliable and agile handling.
* Crash safety is of the extremely high standard associated with Mercedes thanks to the sandwich concept and the housing of major powertrain components between the axles.
As a result, the BlueZero models are very different to conventionally constructed electric cars, which have the heavy and voluminous storage battery housed in the boot or in the rear-seat area.

Modular design ensures flexibility and efficiency
The modified sandwich-floor platform provides the perfect basis for a wide model range with electric drive systems. We are also developing a new, additional platform for future compact models with power units based on optimised internal combustion engines. The intelligent networking of both architectures enables us to develop our product portfolio extremely flexibly and efficiently. From 2009, we will be producing the first Mercedes fuel-cell cars on a small scale. Small-scale production of Mercedes-Benz cars with battery-electric drive alone will then commence in 2010. This means we are extremely well equipped for the future."

Electric drive systems with a range of 100, 200 and well over 400 kilometres
With a charging capacity of 15 kW, the powerful lithium-ion batteries in the BlueZero E-CELL and the BlueZero E-CELL PLUS can store enough energy for a range of 50 kilometres within 30 minutes. In terms of purely electrical drive, one or two hours of charging time is needed for a range of 100 and 200 kilometres respectively. The charging times are doubled if the charging capacity is 7 kW, as would be the case in a normal household. Both of these BlueZero vehicles incorporate an electronic control unit that supports intelligent charging stations and billing systems.


The BlueZero E-CELL PLUS has the same 1.0-litre turbocharged petrol engine as the smart fortwo as an additional range extender. This compact three-cylinder powerplant has an output of 50 kW at a constant 3500 rpm. If required, it can recharge the 17.5-kWh lithium-ion battery by means of a similarly rated alternator. A range of up to 600 kilometres is possible on a single tank. The purely electrical, locally emission-free range is up to 100 kilometres. The BlueZero F-CELL with fuel-cell drive achieves a range of well over 400 kilometres with zero emissions (as per NEDC).

BlueZero design: both elegant and functional
Leading-edge technology is uniformly and attractively packaged in all three BlueZero variants. The unique and distinctive Mercedes design idiom displayed by the body highlights the progressive nature of Mercedes-Benz BlueZero Concept straight away.
The powerfully elegant front end is dominated by the radiator grille with its centrally located star. The excellent aerodynamics of the BlueZero are partly due to the closed front apron, whose design means that cooling air intakes are not required. The 20-inch wheels have also been aerodynamically optimised, while low-friction tyres reduce rolling resistance.
The striking character lines along the flanks lend the BlueZero an extremely dynamic side line and accentuate its bionic structure inspired by nature. This characteristic feature of the Mercedes-Benz bionic car was adapted and modified for the BlueZero models. These elements lend the body its dramatic power.

New-quality light production
The compact rear end of the Mercedes-Benz BlueZero Concept is characterised by tail lights in the shape of a curved "L". In addition, the Mercedes designers have achieved a new-quality light production: transparent lenses produce a red light curtain which tapers smoothly towards the sides, creating a lightly diffused effect. This effect is repeated, albeit in white this time, by the front headlamps. What's more, the front lights feature new lens technology and a plexiglass edge to produce "C" shaped daytime driving lights with the help of state-of-the-art LED technology.

Intelligent technology made visible
Translucent surfaces make the normally concealed technology visible. The light-grey tailgate is made completely from lightweight but highly robust Lexan that allows a view of the aluminium structure that makes up the rigidifying frame, for example. At the same time this transparent tailgate provides a view of the vehicle interior, making the advantages of the sandwich-floor platform obvious at a glance: for maximum customer benefit, the luggage compartment and passenger area remain fully usable, since there are no technical components that need to be accommodated here.

The Mercedes-Benz designers have emphasised this aspiration by introducing paint finishes in three new ALU-BEAM colours. Each of the three variants makes its individual mark: the BlueZero E-CELL is painted in a fresh ALU-BEAM Yellow, while the BlueZero F-CELL has ALU-BEAM Green paintwork. Confidence-oozing ALU-BEAM Orange was chosen for the BlueZero E-CELL PLUS.
