Mercedes-Benz is showing the way ahead in responsible electromobility by presenting its Concept BlueZERO at the North International Auto Show in Based on a single vehicle this intelligent, modular allows three models different drive configurations, all of are able to meet customer in terms of sustainable mobility:

the E-CELL with battery-electric and a range of up to 200 kilometers using drive alone

the BlueZERO (fuel cell) with a of well over 400 kilometers electric drive

the BlueZERO PLUS with electric and additional internal combustion as power generator (range This version has an overall of up to 600 kilometers and can cover a distance of up to 100 using electric drive

The three BlueZERO variants are on the unique sandwich-floor architecture Mercedes-Benz introduced some ten ago, initially for the A-Class and for the B-Class, one of the aims being to alternative drive systems. of the modified construction include the effect of the major drive on the centre of gravity, their design, and the fact that are extremely well protected the vehicle underbody. The five-seater concept cars also set in terms of lightweight design, layout, and body form.

flexible BlueZERO concept electromobility for every requirement and the fact that Mercedes-Benz is the only car manufacturer to already in place all the key technologies for electric offering full everyday says Dr. Dieter Zetsche, of the Board of Management of Daimler AG and of Mercedes-Benz Cars.

The BlueZERO flexible design, compact and generously sized interior

All BlueZERO variants share the key technical components, while the and vehicle dimensions are identical. just 4.22 meters in the BlueZERO models combine exterior dimensions with a proportioned and variable interior and compartment. Five fully-fledged a payload of around 450 kilograms, and a compartment capacity of over 500 make for outstanding everyday Thanks to their sandwich with a raised sitting the cars also offer an high level of crash for the passengers and the technology, not to mention all-round visibility.

Compared to cars based on conventional platforms and originally only for use in combination with internal engines, Concept BlueZERO the following conclusive advantages:

space is retained in full. As the accumulators/generators are integrated into the sandwich floor, no compromises are with respect to passenger luggage capacity, or variability.

The technology built into the floor ensures a low centre of and, consequently, extremely and agile handling.

Crash is of the extremely high standard with Mercedes thanks to the concept and the housing of major components between the axles.

As a the BlueZERO models are very to conventionally constructed electric which have the heavy and storage battery housed in the or in the rear-seat area, for example.

design assures flexibility and

“Our modular system different drive configurations for customer requirement”, says Dr Weber, the member of the Daimler AG of Management responsible for corporate and development at Mercedes-Benz Cars. modified sandwich-floor platform the perfect basis for a wide range with electric systems. We are also developing a additional platform for future models with power based on optimized internal engines. The intelligent networking of architectures enables us to develop our portfolio extremely flexibly and From 2009, we will be the first Mercedes fuel-cell on a small scale. Small-scale of Mercedes-Benz cars with drive alone will commence in 2010. This we are extremely well equipped for the

All three BlueZERO models front-wheel drive, which is for this class of car. The engineers have put together a system comprising several combinable drive components. include state-of-the-art liquid-cooled batteries with a storage of up to 35 kWh and the compact electric motor a maximum output of 100 kW (continuous 70 kW), which develops a torque of 320 Nm. All three variants from 0 to 100 km/h in less 11 seconds. Their top speed is limited to 150 km/h in the interests of range and energy efficiency.

drive systems with a of 100, 200, and well 400 kilometers

With a charging of 15 kW, the powerful lithium-ion batteries in the E-CELL and the BlueZERO E-CELL can store enough energy for a of 50 kilometers within 30 minutes. In of purely electrical drive, one or two of charging time is needed for a of 100 and 200 kilometers respectively. The charging are doubled if the charging capacity is 7 kW, as be the case in a normal household. of these BlueZERO vehicles an electronic control unit supports intelligent charging and billing systems.

At the rear, the E-CELL PLUShas the same turbocharged gasoline engine as the fortwo as an additional range This compact three-cylinder has an output of 50 kW at a constant 3500 If required, it can recharge the 17.5-kWh battery by means of a similarly alternator. A range of up to 600 kilometers is on a single tank. The purely locally emission-free range is up to 100 The BlueZERO F-CELLwith fuel-cell achieves a range of well 400 kilometers with zero (as per NEDC).

BlueZERO design: elegant and functional

Leading-edge is uniformly and attractively packaged in all BlueZERO variants. The unique and Mercedes design idiom by the body highlights the progressive of Concept BlueZERO at first

The powerfully elegant front end is by the radiator grille with its located star. The excellent of the BlueZERO are partly due to the closed apron, whose design that cooling air intakes are not The 20-inch wheels have been aerodynamically optimized, low-friction tires are fitted to rolling resistance.

The striking lines along the flanks the BlueZERO an extremely dynamic line and accentuate its bionic inspired by nature. This feature of the Mercedes-Benz bionic car was and modified for the BlueZERO models. elements lend the body its power.

New-quality light

The compact rear end of the Concept is characterized by tail lights in the of a curved “L”. In addition, the designers have achieved a light production: transparent produce a red light curtain tapers smoothly towards the creating a lightly diffused This effect is repeated, in white this time, by the headlamps. What’s more, the lights feature new lens and a plexiglass edge to produce “C” daytime driving lights the help of state-of-the-art LED technology.

technology made visible

surfaces make the normally technology visible. The light-gray is made completely from but highly robust Lexan, a view of the aluminum structure makes up the rigidifying frame, for At the same time, this tailgate provides a view of the interior, making the advantages of the platform obvious at a glance: for customer benefit, the luggage and passenger area remain usable, since there are no components that need to be here.

“It was very important for us to that the guiding Mercedes-Benz of ‘Fascination and Responsibility’ was clearly in the design of the Concept BlueZERO”, Mercedes-Benz design chief Wagener. “This is yet another statement that environmental and driving pleasure will to go together in our vehicles in the future. We people to realize at first that the Concept BlueZERO is not a lesser option.”

The Mercedes-Benz designers have this aspiration by introducing finishes in three new ALU-BEAM Each of the three variants its individual mark: the BlueZERO is painted in fresh ALU-BEAM while the BlueZERO F-CELL has green paintwork. Confidence-oozing orange was chosen for the BlueZERO PLUS.

Extended version

Concept BlueZERO: three-fold of the everyday practicality of zero-emission

Current challenges such as worldwide mobility requirements, crude oil reserves, and increasingly exhaust emission regulations are the electric car more and more a of public attention. Thanks all to major advances in battery electric drive is seen as a answer to the question of how individual can be made sustainable.

Battery-electric systems offer a wealth of in this respect: they a high level of torque, are and quiet, run extremely efficiently and zero local emissions, and operate without the need for fuels. However, it is not currently to fulfill all mobility requirements a single electric vehicle Those who drive predominantly or exclusively in urban areas do not as much emphasis on vehicle but very much like the of lower noise levels and For such customers, a battery-electric is an attractive solution.

Those who wish to cover long on country roads and motorways with low noise levels, no emissions, and short refueling have a viable alternative in the of the fuel-cell electric vehicle. technology clearly shows the way in terms of sustainable mobility the “crude oil age” but requires a infrastructure. The beneficial combination of range, fast energy on board from an existing and noiseless and locally emission-free in urban areas is offered by a vehicle with range

Concept BlueZERO: modularity optimal everyday practicality

The architecture and the modular design three different drive that are able to meet an wide range of different Measuring 4.22 meters in 1.89 meters in width and meters in height, the extremely BlueZERO concept offers design advantages over cars based on conventional platforms and designed only for use in with internal combustion

Interior space is retained in As the energy accumulators/generators are integrated the spacious sandwich floor, no are necessary with respect to space, luggage capacity, or

The powertrain technology located in the floor and integrated directly at the axle assures a low centre of and, consequently, extremely and agile handling.

Crash is of the extremely high standard with Mercedes thanks to the housing of the powertrain components the axles.

Furthermore, all three electric cars are highly for electromobility in urban areas on of their compact dimensions, entry and exit, raised position, and optimal all-round All of which makes Mercedes-Benz the and, to date, only car in the world to offer three solutions that meet all electromobility requirements.

Intelligent platform assures the highest level of safety

Featuring a version of the sandwich-floor platform, the concept sets standards for the car sector in all areas relevant to motoring. The best possible safety is assured, since all of the drive components are housed the sandwich floor, that is to say in the area between the axles.

for this class of car, all versions of the Concept BlueZERO are drive models with an motor at the front axle. The are located in the center of the vehicle behind this, in a position protects against intrusion in the of a frontal or rear impact, the energy accumulators are located of the body’s impact and deformation Furthermore, the extremely robust of the sandwich floor can offer a level of protection for both the and the occupants, even in the event of a collision. This advantage is of economic benefit, since the is the largest cost factor in drive systems. Consequently, if the remains undamaged in an accident, the costs are reduced considerably. By of its proven nutshell effect, the floor is the safest place for the still relatively expensive accumulators.

Room for five occupants and thanks to highly efficient use of

This clever sandwich also has obvious advantages packaging is concerned: locating the modules in an underfloor position it possible to retain all of the passenger and space in this 4.22-meter five-seater, with no restrictions In the purely battery-powered BlueZERO for example, up to two of the lithium-ion battery developed by Mercedes-Benz can be accommodated in the floor.

In addition to exemplary and unrestricted everyday practicality, the models have further that are by no means the norm for cars, namely agility and enjoyment. This is in large due to the low centre of gravity, another of the low installed position within the floor, and the front axle In combination with uncompromising to centered masses, this in outstanding roadholding and handling

Modular drive concept for configured electric vehicles

will present two BlueZERO at the 2009 NAIAS show in the BlueZERO E-CELL as a purely vehicle and the fuel-cell version, the F-CELL – both of which are in local operation. Mercedes-Benz engineers are also working on a version with a range the BlueZERO E-CELL PLUS. is additionally equipped with a internal combustion engine as a that produces power a journey.

All these models battery packs based on the lithium-ion technology. This new technology has decisive advantages conventional battery types, them very compact significantly higher performance, reliability, and a long operating The identical components used in the system also include the permanent-magnet synchronous electric which operates at a maximum of rpm. It develops a peak of 100 kW and a continuous output of 70 kW. Its peak is 320 Nm, while the continuous torque is 180 Nm. The torque is available from the revolution of the electric motor and the figure achieved by a current V6 engine at 2500 rpm.

E-CELL: agile, quiet and emission-free

The BlueZERO E-CELL is with a lithium-ion battery a capacity of 35 kilowatt hours The liquid-cooled high-voltage cells an operating voltage of 240 to 426 V. With battery, the BlueZERO E-CELL has an range of up to 200 kilometers. Recharging the battery takes three to hours. The BlueZERO E-CELL from zero to 100 km/h in than eleven seconds in the interests of optimal range and efficiency, has an electronically limited top of 150 km/h.

BlueZERO F-CELL: driving on long journeys the fuel cell

The new-generation cell used in the BlueZERO is more compact and – with a output of 90 kW (continuous output 80 kW) – more powerful than its It can be cold-started at temperatures down to 25 degrees Celsius and also has the of short refueling times.

On the the BlueZERO F-CELL assures a standard of dynamic handling, yet family-friendly compact car consumes 2.9 liters of fuel (diesel per 100 kilometers. According to the NEDC, the F-CELL is able to cover over 400 kilometers on one tank of

In the fuel cell version of the the electric motor, high-voltage and hydrogen tank are likewise beneath the passenger cell to space. The system uses the efficient energy source for the driving situation. When or maneuvering at slow speed, for the electric motor uses battery power. When energy is provided by both the cell and the battery. When the electric motor acts as a and charges the battery. This system therefore makes use of the that would be converted heat during conventional and stores it in the powerful lithium-ion

For longer journeys too, sees the fuel cell as one of the key for zero-emission driving. Providing a network of hydrogen filling is in place, this technology ideal possibilities for sustainable well into the future. The fuel cell combines emissions with a long range, since electrical is generated on board during the There are no exhaust emissions and no CO2 is emitted either. The BlueZERO emits nothing more steam. Moreover, a fuel drive system is almost as efficient as an internal combustion

BlueZERO with range flexible solution with a range

In the third version, the E-CELL PLUS, the Mercedes combine the electric drive from the purely battery BlueZERO E‑CELL with an internal combustion engine serves as a range extender. The 50-kW three-cylinder turbocharged engine from the smart charges the battery whilst the car is driven.

Advantage of the range as with conventionally powered equipped with a gasoline or engine, the customer benefits a significantly longer range (up to 600 especially as the BlueZERO E-CELL can also be quickly and easily at any normal filling station. The can therefore be sure that the car is for use anywhere and at any time. And when an area is reached after an journey, the driver can continue on way under electric power

The BlueZERO E-CELL PLUS allows electric mobility at the of a button, a particular benefit in populated urban areas environmental zones, toll and other access restrictions cars with internal engines.

The BlueZERO E-CELL with the range extender highlights the advantages of the sandwich-floor here too, the key drive are integrated in the underfloor area to space. The internal combustion is installed near the rear in the spare wheel well. to the range extender, the BlueZERO PLUS has a range of up to 600 kilometers, of 100 kilometers are in locally emission-free mode, with no drop in The NEDC fuel consumption is 4.5 per 100 kilometers. In conjunction with a battery and the resulting CO2 bonus, the car just 32 grams of CO2 per kilometer.

In the highly efficient modular allows further variants to be configured. If the system is designed the internal combustion engine as a range extender can also be temporarily as a direct drive – when driving on country for example. This setup the full battery capacity for driving in town. Other variants might be to use the fuel as a range extender, or a combination of the cell and plug-in batteries. to this versatility, the Mercedes-Benz electric drive concept is to cover every conceivable for electric driving.

Instead of a filler cap, the car features connectors to EU and US standards for rapid with electrical power. One is intended for conventional power that fit any household power The second is suitable for connection to recharging stations.

BlueZERO both elegant and functional

technology is very attractively in all the BlueZERO variants. The future-oriented yet Mercedes-style body contours the progressive nature of the Concept at first glance.

Mercedes-Benz BlueZero F-Cell

The Mercedes-Benz have emphasized this by introducing paint finishes in new ALU-BEAM colors. Each of the variants makes its individual the BlueZERO E-CELL is painted in ALU-BEAM yellow, while the F-CELL has ALU-BEAM green Confidence-oozing ALU-BEAM orange was for the BlueZERO E-CELL PLUS.

The lenses are by supports which also as direction indicators.

Aerodynamic with eye-catching effects

The grille with its centrally star and even more V‑shape is a striking reinterpretation of the Mercedes-Benz radiator grille. The aerodynamics of the BlueZERO are partly due to the front apron, whose dispenses with any cooling air The 20-inch wheels are also optimized. Low-friction tires are to reduce rolling resistance.

many other design the wheel covers are transparent and a view of wheel spokes, are visually enhanced with light effects. All BlueZERO are also equipped with a lightweight panoramic roof which solar panels been integrated. The thin-layer used here allow 20 of the light into the interior. enough sunlight, they sufficient electric power to cell phones or mobile for example.

Progressive interior

The interior features an all-new, design idiom: the lines are and blend in subtly with the surfaces. The Concept BlueZERO is a continuation of the bionic design and is similar to the Mercedes-Benz bionic A wealth of structures inspired by and modeled based on organic can be found in several of the paneling in the door stowage areas, the the centre console, the load and the load sill guard.

The of colored transparent surfaces the interior a feeling of lightness. is enhanced by semi-transparent surfaces edges form striking breaks. This interplay transparency and edge emphasis extremely well with the design idiom. The suggested conductor paths in the center represent the advent of a future technology.

of makes the vehicle interior much more open. As a the Concept BlueZERO offers the and functionality of a modern-day compact

The material concept is largely on a tone-in-tone composition enriched by of color. By way of example, the belt and the seam thread in the paneling establish a link with the exterior, while the leather in the seats creates a visual with the high-quality steering

Thanks to their surface the materials are highly resistant. The mix of textiles and plastics combines a level of value with appeal.

Concept BlueZERO: a for efficient electromobility

With the concept studies, Mercedes-Benz a very specific outlook on the future of electric motoring. components of this modular concept will shortly be in standard-production cars made by These include the fuel drive system, which enter small-scale production in In 2010, the first Mercedes-Benz car will also be introduced small-scale production.

Modular as a strategic guideline

With intelligently conceived modular Mercedes-Benz will also be to realize tailor-made drive for individual requirements in the electric car For the brand’s clients, this a wide choice of purpose-made, and affordable solutions.

The product presented by Mercedes-Benz on its “Road to the is uncompromisingly wedded to the modular principle: modular drive that can be used individually or in depending on vehicle class, profile, and customer requirements are a key in this.

Modular drive also for hybrid vehicles

particularly applies to hybrid such as the S 400 BlueHYBRID, which is due to be in 2009 as the most economical luxury saloon and CO2 champion in its For its hybrid models with and diesel engines, Mercedes-Benz has a modular system which can be with respect to performance and of applications.

In the S 400 BlueHYBRID, the hybrid with its start-stop function, and boost effect already considerable savings possible.

a suitable configuration, it is also to drive under electric alone with this module, while the operating in electric mode depends on the capacity.

The plug-in hybrid a further step, where the can also be charged from the in order to increase the electric range.

Intelligent drive mix for mobility

In the view of Mercedes-Benz, will be no single technology as the solution for sustainable mobility in the Instead the company is responding to the requirements with equally solutions. The respective advantages of the technologies in terms of optimal consumption and emission values are in specific application areas. is basing its strategic planning for the of individual mobility on the following mix of systems:

For long-distance operations, internal combustion engines or without a hybrid module be used, as well as fuel powered vehicles.

For rural plug-in hybrids will be added to the mix.

For urban locally emission-free vehicle with battery and fuel-cell systems are considered to be the most

The electric drive configuration in the Concept BlueZERO does justice to this requirement Mercedes-Benz has conducted intensive in the field of fuel cell since as early as 1991 therefore, has enormous experience electro- mobility. The brand has the largest fleet of fuel powered vehicles undergoing trials, for example.

And in the field of vehicles, the company has also unrivalled experience from trials involving 100 smart drive cars in London. The BlueZERO impressively reflects in-depth know-how.
