Η Daimler γιορτάζει τα 125 χρόνια από τότε που ο Carl Benz κατέθεσε δίπλωμα ευρεσιτεχνίας για την πρώτη αυτοκινητοβιομηχανία του κόσμου που θα κατασκεύαζε αυτοκίνητα που θα κινούταν αποκλειστικά με κινητήρες εσωτερικής καύσης. Η Daimler εκτός του bonus που έδωσε τους υπαλλήλους της, δημιούργησε ένα γλυπτό για να το γιορτάσει ενώ παράλληλα διοργάνωσε και μια εκδήλωση όπου παραβρέθηκε η Γερμανίδα καγκελάριος Angela Merkel, αλλά και ο πρωθυπουργός του κρατιδίου της Βάδης-Βυρτεμβέργης, Stefan Mappus.
Το γλυπτό ονομάζεται Aesthetics 125 και δείχνει την φιλοσοφία των σχεδιαστών, για το πως θα μοιάζουν τα μελλοντικά μοντέλα της Mercedes-Benz, όπως ακριβώς έχει γίνει και με τα Aesthetics No. 1 και Aesthetics No. 2. Το νέο γλυπτό συνδυάζει στοιχεία του εσωτερικού και του εξωτερικού ενός αυτοκινήτου.
Η Daimler αναφέρει ότι θα γίνουν αρκετές ειδικές εκδηλώσεις σε όλο τον κόσμο ενώ παράλληλα ανακοίνωσε ότι ξεκινά η περιοδεία των αυτοκινήτων της σειράς F-CELL, μέσω της καμπάνιας Mercedes-Benz F-CELL World Drive. Η περιοδεία θα διαρκέσει 125 μέρες και τα 3 αυτοκίνητα B-Class F-Cell θα ταξιδέψουν σε 14 χώρες.
Να θυμίσω ότι η B-Class F-Cell είναι ένα από τα μοντέλα του πράσινου οράματος της Daimler, το οποίο διαθέτει έναν κινητήρα που χρησιμοποιεί το υδρογόνο καθώς και τον αέρα της ατμόσφαιρας για να παράγει ηλεκτρικό ρεύμα. Ο κινητήρας αποδίδει 136 άλογα με 29 κιλά ροπής με την αυτονομία του να ανέρχεται στα 400 χλμ.
Τέλος δημιούργησε ένα video με τα αυτοκίνητα του μουσείου της να παίζουν με τις κόρνες τους το γνωστό τραγούδι “Happy Birthday”.

Exactly 125 years to the day after Carl Benz registered his “vehicle with gas-engine drive” under patent number 37435 with the Berlin Patent Office in 1886, Daimler AG has celebrated the anniversary of the automobile. Approximately 1,400 invited guests were hosted by the inventor of the automobile at the Mercedes-Benz World in Stuttgart. The evening was moderated by Desirée Nosbusch with guests of honor including the German Federal Chancellor, Dr. Angela Merkel, and the Prime Minister of the federal state of Baden-Württemberg, Stefan Mappus. They mixed with international guests from the automotive industry and the fields of politics, business, sports, society and the media, as well as members of Daimler’s Board of Management, Supervisory Board and many Daimler employees.
Dr. Dieter Zetsche, Chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz Cars, emphasized the importance of the automobile: “The invention of Daimler and Benz has changed the world for the better – and it will continue to do so. History shows that when a society becomes physically mobile it also becomes socially mobile and economically successful.” At the same time, Dr. Zetsche focused on the future: “As the inventor of the automobile, Daimler strives to be at the forefront of shaping future mobility.”
One of the key challenges is the transition to electric mobility.
Dr. Zetsche is convinced: “If Daimler and Benz were still alive today, they would advise us to make green cars even more fascinating and fascinating cars even greener. Only attractive innovations are effective innovations.” World tour of fuel cell vehicles to be started Firm evidence of the innovative strength of Daimler and Mercedes-Benz in the field of green technologies was sent on a world tour as part of the anniversary celebrations. Together with Chancellor Merkel, present and past racing drivers Michael Schumacher, Nico Rosberg and David Coulthard, and three Daimler engineer, Dr. Zetsche symbolically started the Mercedes-Benz F-CELL World Drive. Three B-Class cars with fuel-cell drive are to travel around the world in 125 days.
Patent granted for battery technology
125 years after Carl Benz registered his patent and more than 80,000 patents later, Daimler was granted another technology patent during the anniversary celebrations. Cornelia Rudloff-Schäffer, President of the German Patent and Trade Mark Office, presented Dr. Zetsche with the patent certificate for the so-called bipolar flat-cell frame. This technology is now in the development stage at Daimler and is potentially a further step along the way to the industrialization of lithium-ion batteries.
Milestone: 30 million Mercedes-Benz cars
Right on time for the 125th anniversary of the automobile and after 65 years of post-war production, the Mercedes-Benz brand has reached a new milestone. 30 million automobiles with the three-pointed star have been delivered to customers since 1945. Dr. Dieter Zetsche: “This unit-sales jubilee is another major milestone in the history of our brand and demonstrates the popularity our cars have enjoyed for many decades with customers around the world.”
Sculpture “Aesthetics 125”
The latest sculpture from the Mercedes-Benz design team, “Aesthetics 125,” was unveiled during the celebrations. The sculpture continues the unique designers’ philosophy that “Mercedes-Benz design is art” and is an extension of the sculptures presented previously, “Aesthetics No. 1” and “Aesthetics No. 2.” Like them, “Aesthetics 125” provides an outlook on the future design language of Mercedes-Benz. It combines elements of an automobile’s interior and exterior by means of sweeping, almost soaring shape transitions. The model was made by the Mercedes designers using the innovative rapid-prototyping technology, which enables digital data to be transferred directly to a design object. The technology works with various materials and applies them in fine layers so that no waste material is produced when a sculpture is created. Start of numerous activities
The anniversary celebrations at the Mercedes-Benz World mark the official start of jubilee year 2011, which Daimler has given the motto “125! years inventor of the automobile.” The Mercedes-Benz brand has given the year the motto “125! Years of innovation.” Numerous events connected with the 125th anniversary of the automobile are scheduled to take place this year. Special bonus for the worldwide workforce Daimler’s success – in the past, the present and the future – depends above all on the motivation and enthusiasm of its approximately 260,000 employees all over the world. For this reason, many activities and projects will be taking place in the coming year that focus on the employees. First of all, Daimler will pay out a total of 125 million euros to its worldwide workforce in the form of a special anniversary bonus. In recognition of the efforts and achievements of recent years, each employee will receive a bonus of up to 1,000 euros depending on his or her length of time at the Group. Support for the Gottlieb Daimler and Karl Benz Foundation
In addition to the special bonus to be paid to the employees, Daimler is also making a gesture of social responsibility, and will increase the capital of the Gottlieb Daimler and Karl Benz Foundation (www.daimler-benz-stiftung.de) to 125 million euros. This foundation was established in 1986 – the year of the 100th anniversary of the automobile – and deals primarily with long-term research projects concerning the ever changing relationship between human beings, the environment and technology. The capital increase is intended to develop the foundation into a think tank specializing in this field.
“We move it! – 125 employee projects for sustainability”
There will be a very special event to honour employees’ social involvement: “We move it! – 125 employee projects for sustainability”. Employees in Germany can apply presenting environment- and community-related projects to which they dedicate their free time as volunteers. A jury of experts will select 125 projects which will then be supported or financed by Daimler with up to 5,000 Euros per project. Every employee already working, or wishing to work, for a non-profit organisation or in a public corporation can take part. Applications can be submitted starting January 29, 2011. Similar campaigns will be started in other countries such as Brazil and France.
Celebrations for employees and their families
In 2011, at virtually all the Daimler locations around the world, employee and family festivities will be organised. The celebrations at the multiple Daimler locations are intended as a “thank-you” to the workforce. For today’s celebration, 125 invitations were raffled amongst employees. Apart from this, in different events, Daimler will also raffle tickets for the international football match in the Mercedes-Benz Arena and numerous other prizes.
Exhibitions around the world
The central anchor point for the automobile’s history is the Mercedes-Benz Museum, which in 2011 celebrates its 5th anniversary at its new home in the Mercedes-Strasse in Stuttgart. In addition to the museum’s automotive classics, the guest exhibition ART 125! will be on show here from May to September 2011. Over 160 exhibits from the company’s collection of modern and contemporary art created by more than 80 internationally renowned artists will be on display. Among the works of art that will be seen there are many which originated in the artist’s treatment of the history, models or design of Mercedes-Benz motor cars. Worthy of mention among these: Andy Warhol’s (1928-1987) legendary series of paintings “CARS”, created by the artist 25 years ago on the occasion of the 100th anniversary of the automobile. Beside further works with reference to the motor car by Bertrand Lavier, Robert Longo, Sylvie Fleury and Vincent Szarek among others, in the Mercedes-Benz Museum it will be possible to see for the first time a work commissioned for the automobile’s 125th birthday.
A publication is to be edited in the form of a book with 125 anecdotes revolving around the motor car, entitled “125 moving stories”. The reader can learn entertaining, informative and surprising stories – some of which have never been set down in writing before.
Exhibitions will be staged at the international Mercedes-Benz Galleries, Mercedes-Benz Brand Centres and the German Mercedes-Benz customer centres, featuring selected historic and present-day exhibits to illustrate the influence the invention of the motor-car had on society and to bear witness to Mercedes-Benz’s power of innovation – not least keeping an eye on the future of mobility. In addition, Daimler will implement a travelling exhibition of classic vehicles, which is to tour selected shopping centres throughout Germany and thus make automobile history tangible for millions of people.
Mercedes-Benz as sponsor of the 2011 Automobile Summer The State of Baden-Württemberg celebrates the invention of the automobile with a series of events under the heading “Automobile Summer 2011– 125 years of the automobile”. Over 125 days numerous events will take place in Baden-Württemberg, grouped into eight thematic blocks: Family & Children, Origin & History, Art, Culture & Lifestyle, Technology & Research, Travel & Pleasure, Environment & Sustainability, Motor sport & Tuning as well as Wellness & Health. Five of these are planned in Stuttgart, Karlsruhe, Pforzheim, the Lake of Constance region and Mannheim. The event series will begin in Stuttgart on May 8 to finish in Mannheim on September 10. Daimler is actively supporting the 2011 Automobile Summer with its brand Mercedes-Benz acting as a sponsor.
Mercedes-Benz says “Thank you”
Starting in mid-August Mercedes-Benz will initiate activities in Stuttgart, planned to take place on several days and intended to enable members of the public to participate actively in the jubilee celebrations. An international soccer match between the German National Team and the Brazilian selection in the reconditioned Mercedes-Benz Arena in Stuttgart on August 10, 2011 will be the kick-off; Mercedes-Benz acting as “Sponsor of the day”. On subsequent days Mercedes-Benz will offer multi-media performances, vehicle exhibitions and, both for young and old, a glimpse at the future of the motor car. This “Thank you” event will also be incorporated in the event calendar of the Automobile Summer of the State of Baden-Württemberg.
In addition, this summer Mercedes-Benz, working in close cooperation with the international official Mercedes-Benz Clubs in Berlin is organising the biggest Mercedes-Benz meeting of all times.
Retrospect:125 years of innovation in automotive construction
When Carl Benz registered his Patent number 37435 in Berlin on January 29, 1886, nobody could possibly have imagined the triumphant march the modern motor car would embark upon over the following 125 years. Less than 100 kilometres away, and almost at the same time, Swabian inventor and entrepreneur Gottlieb Daimler was working on his motor wagon, to which he gave the finishing touches that very year. However, both had to wait some years before the groundbreaking development they had succeeded in initiating became a profitable commercial proposition.
The long road to the birth of the modern-day automobile
As far back as the eighteenth century there had been first experiments with automobiles driven by steam engines, in particular in England and France. In the course of the 19th century countless engineers, developers and inventors all over Europe worked at the further development of steam engines. Electric motors were also tried for the first time. However, the decisive steps that led to Gottlieb Daimler and Carl Benz’s invention of the modern motor car took place in Germany with the invention of the four-stroke engine (gas engine) by Nikolaus August Otto. Both Daimler and his congenial partner, Wilhelm Maybach, as well as Carl Benz realised that their opportunity lay in the reduction of size and weight of the engine coupled with an increase in power output at the same time. The resoluteness with which Carl Benz and Gottlieb Daimler developed their ideas further, and patented, implemented and tested them to finally lead to their application in series production and market maturity, makes them the fathers of an invention that was to change the world – socially, culturally and economically.
Zero-emission vehicle sets off on automotive marathon: Starting shot fired for F-CELL World Drive
Starting shot fired for F-CELL World Drive
As part of the ceremony to mark the 125th birthday of the invention of the motor car on 29 January in Stuttgart, German Chancellor Dr. Angela Merkel and Dr. Dieter Zetsche, Chairman of the Board of Management of Daimler AG, fired the symbolic starting shot for the Mercedes-Benz F-CELL World Drive. Setting out from Stuttgart on 30 January, three Mercedes-Benz B-Class vehicles featuring local zero-emission fuel cell drives are undertaking a 125-day circumnavigation of the world. Travelling across four continents and through 14 countries, the three B-Class F-CELL vehicles will head around the globe once, finishing their “world tour” back in Stuttgart where they started. With the F-CELL World Drive, Mercedes-Benz is aiming to confirm the technical maturity of fuel cell technology, as well as the suitability for everyday use of the vehicles. At the same time, the company will also take the opportunity to enforce the political call to establish a comprehensive filling station infrastructure for fuel cell vehicles.
On January 29, 1886, Carl Benz filed the patent for his three-wheeled “vehicle with gas engine operation” under number 37435, thus setting the first milestone for a completely new form of mobility. Some 125 years to the day later – on 29 January 2011 – Daimler AG is taking this date as an opportunity not only to look back through history and highlight the milestones of automotive development, but also to give a specific insight into the future of mobility. The symbolic start of the F-CELL World Drive, the first circumnavigation of world using standard-production fuel cell vehicles, therefore also took place as part of the celebrations. After the three Mercedes-Benz B-Class F-CELL vehicles – which are starting their long journey on January 30 – were driven onto the stage by Mercedes-Benz racing drivers Michael Schumacher, Nico Rosberg and David Coulthard, the symbolic starting shot was fired by Dr. Dieter Zetsche, Chairman of the Board of Daimler AG, together with German Chancellor Dr. Angela Merkel.
29 January 2011 Over a route covering 30,000 kilometres, the three Mercedes-Benz B-Class F-CELL vehicles will demonstrate that they are a safe and reliable means of transport over long distances and in the widest variety of road and weather conditions. “Some 125 years after the invention of the motor car, for us the B-Class F-CELL embodies its reinvention”, explains Dr. Dieter Zetsche, Chairman of the Board of Management of Daimler AG, commenting on the significance of the innovative fuel cell vehicle. “As an event which is currently unique, this circumnavigation of the world in customer-ready fuel cell vehicles again demonstrates that we have sufficient pioneering spirit for at least another 125 years of innovation.”
On the road with the fuel cell – mobility with zero emissions and no compromises
Electric vehicles with fuel cell combine the benefits of a long range with a short refuelling time. As a result they are able to make a contribution towards local zero-emission mobility not only in densely populated areas, but also over long-distance routes. In addition, besides their use in passenger cars, fuel cell drives can also be used in a variety of other vehicle types, such as urban buses for example. Mercedes-Benz recognised this potential at an early stage, launching the first vehicle with fuel cell drive, the NECAR 1, as early as 1994. Since that time, the company has made very significant progress in the development of this technology, enabling it in the meantime to reach a very high level of technical maturity. As a result, for the first time all of the development and production standards applicable to series production vehicles have now also been applied to the B-Class F-CELL. All of the F-CELL components comply with the highest of Mercedes-Benz standards in terms of their quality, reliability and service life.
Besides local zero-emission mobility, the B-Class F-CELL also provides all of the brand-typical characteristics, such as safety, comfort, superior performance and also exemplary functionality, in combination with complete suitability for everyday use and unrestricted driving pleasure.
With the F-CELL World Drive, Mercedes-Benz wants to prove the high degree of maturity which has been achieved with fuel cell technology and also highlight its potential on a global basis. At the same time the circumnavigation of the world will also draw attention to a significant challenge: the infrastructure for the provision of hydrogen. “This type of electric mobility can only be implemented on a comprehensive scale when it is backed by a network of hydrogen filling stations designed to meet demand. This filling station network now has to be developed by joining forces,” explains Dr. Thomas Weber, Daimler AG Board Member responsible for Group Research and Development, Mercedes-Benz Cars. “We have done our homework: the B-Class F-CELL shows to impressive effect the contribution which electric vehicles with fuel cell are already able to make to future mobility. The vehicle enables local zero-emission motoring not only over short routes but also over longer distances. We will demonstrate this with our F-CELL World Drive,” confirms Dr. Thomas Weber.
4 continents, 14 countries and 30,000 kilometres in 125 days
Setting off from Stuttgart on January 30, the tour will initially head south via Paris, Barcelona and Madrid, to the Portuguese capital of Lisbon. There the cars will leave European soil and continue their journey by plane to the East Coast of the USA.
From Fort Lauderdale, Florida, the route heads across the North American continent, along the Gulf of Mexico, leading westwards to Los Angeles, California. Then, travelling along the west coast of the USA, the F-CELL World Drive will go north, finally reaching Vancouver, Canada. After driving for roughly one month and covering more than 7500 kilometres, the vehicles will leave North America, in order to continue their tour in the east of Australia. Starting in Sydney, the B-Class F-CELL vehicles will head along the south coast of the fifth continent, covering more than 5000 kilometres, with stopovers in Melbourne and Adelaide, until reaching Perth. The last transfer between continents on the world tour will finally take the F-CELL World Drive to the continent of Asia, to the destination of Shanghai in China.
Travelling via the Chinese capital of Beijing, the fuel cell cars will cover a distance of more than 10,000 kilometres across the continent of Eurasia, heading through the Kazakh cities of Almaty and Astana, to Moscow. This is a stretch of the route with which Mercedes-Benz is already very familiar. In 2006 no less than 33 Mercedes-Benz E-Class vehicles passed through this region, in the opposite direction from Paris to Beijing, as part of the “E-Class Experience”.
On the last stage, the route will head through Northern Europe. From St. Petersburg in Russia, the cars will travel via Finland to the Swedish capital of Stockholm. Oslo in Norway is another destination on the route, before the F-CELL World Drive takes the vehicles via Denmark and back to Germany again, where they will make stopovers in such cities as Hamburg. After 70 days of driving on a journey lasting 125 days, the tour will finally come to an end, back in Stuttgart again, at the beginning of June.
During the F-CELL World Drive, Mercedes-Benz will not only be demonstrating the performance of its vehicles, but at the same time will also make use of the tour to increase global awareness of the potential of fuel cell technology. Local activities providing an opportunity for an intensive exchange of information on the topic of electric mobility will take place on more than 20 days at several locations along the route. The programme will also incorporate politics and partners of the Stuttgart-based automotive manufacturer.
The participants of the tour will therefore pay a visit to the car2go mobility project in Austin, Texas, among others. Austin was the first location for the innovative mobility concept outside of Europe, and the project continues to be extremely successful there. A few days later, the participants will visit the Automotive Fuel Cell Cooperation in Vancouver, Canada. This is where the fuel cell stacks used in the B-Class F-CELL, for example, were developed. The company was established in 2007 with Daimler as the majority shareholder (50.1 percent). The other partners are the Ford Motor Company (30 percent) and Ballard Power Systems (19.9 percent). Furthermore, participants on the Vancouver leg of the tour in Canada will also have the opportunity to meet the adventurer and explorer Mike Horn and experience his PANGAEA Expedition – for which Mercedes-Benz is the main sponsor – first hand. Since October 2008, The PANGAEA Expedition has been visiting all of the continents, including both the North and South Pole. Together with young people from all over the world, expedition leader Mike Horn is setting up ecological and social projects on his journey around the globe. The F-CELL World Drive will also spend several days at “Auto Shanghai” in China, Asia’s largest motor show.
The setting up of a comprehensive hydrogen infrastructure for electric vehicles with fuel cells is an important factor for the market success of this technology. So far there are only approx. 200 filling stations around the world at which fuel cell vehicles can be refuelled. Due to the incomplete supply network, the provision of the tour-vehicles with hydrogen represents a tremendous logistical challenge.
Acting as an exclusive partner on the F-CELL World Drive will be the Linde Group which, thanks to its hydrogen know-how and global presence, is able to guarantee a supply throughout the entire circumnavigation of the world. A jointly developed mobile tanker unit will accompany the tour, thus enabling the supply of fuel even on remote sections of the route. In addition to a refuelling pressure of 700 bar, compact dimensions for transport by air were the most important requirements for the specially designed refuelling vehicle.
Even away from the F-CELL World Drive, Daimler and Linde are also working closely together in order to meet the growing hydrogen demands of an ever-increasing number of fuel cell vehicles in the future. As a result, since 2009 both companies have for example been committed, together with major energy suppliers, corporations in the mineral oil industry and other partners, to the “H2-Mobility” initiative for the comprehensive development of a hydrogen infrastructure in Germany.
On the road to sustainable mobility
In recent years Daimler has clearly positioned itself as a pioneer in the area of alternative drive systems. On the road to sustainable mobility, the company is consistently adopting a “multi-lane” approach. The three core focal points for development are: the optimisation of vehicles with state-of-the-art combustion engines; further efficiency increases with hybridisation tailored to customer needs and in line with demand; and fuel cell and battery-powered vehicles that do not produce any local emissions.
The company is consciously backing several concepts for electric mobility. The battery-powered vehicle has therefore been developed as a zero-emission solution for urban motoring, while vehicles incorporating fuel cells are also suitable for inter-city motoring thanks to their long range and short refuelling times. With the B-Class F-CELL, the A-Class E-CELL, the smart fortwo electric drive and the Vito E-CELL, the company offers four locally zero-emission vehicles, all of which are equally ready for series production.
E-Drive modular system for maximum efficiency
Thanks to its E-Drive modular system, Mercedes-Benz can bring standard-production electric cars to market quickly and achieve optimum cost efficiency. This intelligent modular concept makes it possible to use a high proportion of identical parts for a wide range of electric vehicles with battery or fuel cell. The company-wide use of components saves on development time and costs and ensures more “streamlined” production.
All of the key components of electric vehicles are ideally suited to modularisation: from the electric motor and the transmission, the battery and high-voltage safety concept to the high-voltage wiring, and software modules. Specific components, such as stacks and hydrogen tanks, can be used as standard components for entirely different vehicles in the F-CELL line-up, for instance simply by varying the quantity as necessary: thus the Mercedes-Benz fuel cell bus, for example, is powered by two passenger car systems of the same type that is also used in a B-Class F-CELL. In addition, the B-Class F-CELL is powered by the same electric motor as used in the new A-Class E-CELL.
Powerful lithium-ion batteries
Together with its partners, Daimler is forging ahead with the development of sophisticated lithium-ion batteries. This work forms the basis of customised solutions for its unique product portfolio, which covers practically all mobility requirements. Daimler benefits here from the expertise it has accumulated through many years of research work. To date the company has filed more than 750 patents for battery-powered vehicles – and over 380 of these involve lithium-ion technology. Targeted cooperation with expert partners ensures that the battery systems optimally meet all vehicle and application-specific requirements.
One example is Deutsche Accumotive GmbH & Co. KG, a joint venture between Daimler AG and Evonik Industries AG which focuses on system integration, development and production, as well as research and development of battery systems based on lithium-ion technology. The integration of these company-produced batteries into Daimler vehicles is scheduled to start from 2012.
First electric car fully suited for everyday driving and with the driving dynamics of a two-litre petrol car
Mercedes-Benz is launching its first series-produced electric car with a fuel cell on the road: the new B-Class F-CELL. The small-scale production of the environmentally friendly electric car is already underway. In 2010, the first of around 200 vehicles have been delivered to customers in Europe and the USA. At the heart of the B-Class F-CELL is the new-generation electric drive system powered by a fuel cell, which is compact, powerful, safe and fully suited for everyday use. The fuel cell generates the electrical power on board, while producing little more than pure water and zero emissions. The key drive components are located in the sandwich floor, where they are protected and do not take up much space, leaving the vehicle’s interior and boot fully usable. Thanks to its long range of around 400 kilometres and short refuelling times, the B-Class F-CELL combines local zero-emission mobility with long-distance comfort and compelling performance. Driving pleasure and performance on a par with a 2.0-litre petrol car come courtesy of the 100-kW/136-hp electric motor, which develops effortlessly superior torque of 290 Nm. The B-Class F-CELL consumes the equivalent of 3.3 litres of diesel per 100 kilometres in the New European Driving Cycle (NEDC).
The technology for the B-Class F-CELL drive system is based on the optimised latest-generation fuel cell system. It is some 40 percent smaller than the system in the A-Class F-CELL from 2004, but develops 30 percent more power while consuming 30 percent less fuel. The main drive system components include:
- A compact fuel cell stack
- A powerful lithium-ion battery
- Three 700-bar tanks for the hydrogen and
- A compact, lightweight drive motor at the front axle.
The fuel cell module in the B-Class F-CELL, the stack, boasts outstanding cold-start capability down to minus 25 degrees Celsius. The system features a new humidification system consisting of hollow fibres that ensures, unlike with the first-generation fuel cell, that water no longer freezes in the stack, a characteristic that used to impair cold-start capability. Even at minus 15 degrees Celsius the B-Class F-CELL starts just as quickly as the very latest diesel engine. A dedicated operating strategy helps ensure the fuel cell stack reaches its optimum operating temperature of around 80 degrees Celsius as quickly as possible each time the vehicle is started. Thanks to the powerful cooling system and intelligent temperature management, this ‘pleasant temperature’ is maintained constant under all operating conditions.
Range of around 400 kilometres with the tanks full
The hydrogen used to run the fuel cell is stored in three tanks at a pressure of 700 bar. Each tank holds just under 4 kilograms of the gaseous fuel. The tanks are hermetically sealed from the outside world, preventing the loss of hydrogen into the atmosphere even if the vehicle is left to stand for long periods. Thanks to the high compression ratio, the B-Class F-CELL can cover long ranges of up to 400 kilometres with the tanks full, over twice as far as the A-Class F-CELL. If the tanks are empty, they can be filled simply and quickly in less than three minutes, thanks to a standardised refuelling system.
Equivalent of just 3.3 litres of diesel per 100 kilometres
The electric motor – a permanently excited synchronous motor – develops a peak output of 100 kW/136 hp and a maximum torque of 290 Nm – typical of the high torque generated by an electric motor –, which is available from the instant the engine starts to turn. It ensures that the B-Class F-CELL, whose impressive dynamic handling properties are in some cases far better than those of a two-litre petrol car, gets off to an excellent start. Nonetheless, the local zero-emission electric drive with fuel cells consumes the equivalent of just 3.3 litres of diesel per 100 kilometres (NEDC).
Compact lithium-ion battery with high power density
A powerful high-voltage lithium-ion battery is used to store the power. It boasts an energy capacity of 1.4 kWh and is cooled via the air-conditioning system circuit. When it came to the battery for the B-Class F-CELL, Mercedes-Benz drew on the experience garnered during the development of the lithium-ion technology for the S 400 HYBRID. Advantages of the lithium-ion battery include its compact dimensions and much superior performance compared with nickel metal hydride batteries (NiMH). The energy density is 30 percent higher than with NiMH technology; the power density 50 percent higher by comparison. Furthermore, high recharge efficiency and a long service life make the technology even more compelling.
Intelligent drive system management for superb efficiency
Mercedes-Benz has further enhanced the operating strategy of the electric drive with fuel cells for the B-Class F-CELL. As the outside temperature plummets, the electric motor receives its electrical energy during a cold start both from the lithium-ion battery and from the fuel cell system as it “powers up”. Battery power is sufficient as the outside temperature warms up; the fuel cell then comes on line later – depending on the power requirements. In drive mode, the energy management system constantly maintains the F-CELL system in the optimum operating range. The lithium-ion battery dynamically smoothes out variations with regard to the electrical power required in the current driving situation.
Whenever the driver brakes or as soon as they take their foot off the accelerator, the electric motor converts kinetic energy into electrical energy, which is then stored in the battery, using a process known as recuperation. While manoeuvring or on short journeys, the electric drive motor uses battery power. If the battery capacity is not sufficient, the fuel cell automatically kicks in. In a bid to ensure
optimum efficiency and customer benefits, the intelligent drive management system decides whether the electrical energy is used from the lithium-ion battery, the fuel cell, or a combination of the two systems.
Full everyday practicality
Five seats and a boot capacity of 416 litres make the B-Class F-CELL fully suitable for day-to-day and family use. The key components for the electric drive with fuel cell are optimally protected in the vehicle underbody, thanks to a space-saving design that also promotes a low centre of gravity. Advantages of the design include:
- The generous interior space in the B-Class is fully retained. As the entire fuel cell system is integrated into the spacious sandwich floor, no compromises are necessary with respect to passenger and luggage space as well as variability
- The drive technology built into the sandwich floor ensures a low centre of gravity and, consequently, extremely reliable, agile handling
- Crash safety meets the extremely high standards associated with Mercedes, as the key drive components as well as the hydrogen tanks are placed between the axles.
The B-Class F-CELL offers consummate driving pleasure and full day-to-day suitability – without local emissions. The innovative electric car also has a great deal to offer when it comes to equipment and appointments, including the bonamite silver special paint finish and exclusive 10-spoke light-alloy wheels. In the interior, leather upholstery, heated seats, automatic climate control and the COMAND system, as well as other features, ensure a high level of comfort. The dynamic energy flow display in the COMAND system display keeps the driver constantly abreast of the battery charge status, operating mode of the fuel cell system, as well as providing information on nearby hydrogen filling stations.
Mercedes-Benz applies the same high safety standards to the B-Class F-CELL as to any of its other series-production models. The starting point is the outstanding crash safety of the Mercedes-Benz B-Class, which received the highest five-star rating in the European NCAP (New Car Assessment Programme). The integrated safety concept of the B-Class F-CELL takes the specific characteristics of the innovative drive system into account. The experience garnered over many years by Mercedes-Benz with the electric drive powered by fuel cells from the A-Class F-CELL and the high-voltage technology involving the lithium-ion battery from the S 400 HYBRID went into honing the concept.
Mercedes engineers have tested the safety of the drive-specific components including the hydrogen tanks in the B-Class F-CELL in more than 30 crash tests. The hydrogen tanks are installed in the sandwich floor and therefore well protected in the event of an impact. They hold the hydrogen which is pressurised to 700 bar and have been designed to withstand all conceivable loads. In the event of a crash, safety valves close the hydrogen supply lines to the fuel cell and decouple the tanks from the other system components. Even after a serious accident, the hydrogen poses no risk whatsoever. If a fire leads to excessive heat, a temperature-controlled value vents the tank contents in a controlled manner.
The lithium-ion battery and the high-voltage system in the B-Class F-CELL feature – based on the experience garnered with hybrid technology in the S 400 HYBRID – an extensive, seven-stage safety concept.
- All the wiring is colour-coded to avoid confusion, and marked with safety instructions. This prevents assembly errors in production or in repairs,and makes the quality checks easier to carry out
- Comprehensive contact protection for the entire system by means of generous insulation and dedicated connectors
- The lithium-ion battery is accommodated in a high-strength steel housing.Further safety features: blow-off vent with a rupture disc and a separate cooling circuit. An internal electronic controller continuously monitors the safety requirements and immediately signals any malfunctions
- All high-voltage components are connected by an electric loop. In the event of a malfunction the high-voltage system is automatically switched off
- As soon as the ignition is switched to “Off”, or in the event of a possible malfunction, the high-voltages ystem is actively discharged
- During an accident, the high-voltage system is completely switched off within fractions of a second
- The system is continuously monitored for short circuits
The high level of safety means Mercedes-Benz fuel cell vehicles can use underground car parks, multi-storey car parks or tunnels with no restrictions whatsoever.
