Shortly after the successful market launch of the S 400 HYBRID, currently the most fuel-efficient luxury-segment saloon with a petrol engine, Mercedes-Benz will be presenting the first “three-litre car” in the premium class – the Vision S 500 Plug-in HYBRID – at the 63rd IAA in Frankfurt. The technology vehicle will display the future of Mercedes-Benz’ modular set of hybrid systems. The Vision S 500 Plug-in HYBRID can drive for up to 30 kilometres solely on electricity and therefore without producing any local emissions. The efficient drive system combined with the CO2 bonus for the battery-electric driving mode enables the vehicle to achieve a certified consumption of only 3.2 litres of petrol per 100 kilometers. With CO2 emissions of only 74 grams per kilometre in the NEDC (New European Driving Cycle), the experimental vehicle developed in Sindelfingen demonstrates the long-term viability of future S‑Class generations.
The outstanding values are made possible by the combination of a plug-in hybrid with the efficiency-boosting BlueEFFICIENCY measures. At the same time, the Vision S 500 Plug-in HYBRID has all of the strengths that are typical of the S‑Class: top comfort, outstanding safety and masterful performance. The drive system in the concept car consists of three main components: a powerful V6 petrol engine with a next-generation direct injection system, a 44 kW/60 hp hybrid module and a lithium-ion battery with more than 10 kWh of storage capacity that can be recharged at charging stations. The Vision S 500 Plug-in HYBRID accelerates from 0 to 100 km/h in 5.5 seconds.
“The Vision 500 Plug-in HYBRID is a new milestone on our path toward zero-emission mobility,” says Dr. Dieter Zetsche, Chairman of Daimler AG and Head of Mercedes-Benz Cars. “It is a luxurious and safe S‑Class that offers superior driving performance while at the same time consuming less fuel than current compacts. All of this shows that our top models will also be able to combine automotive fascination with responsibility for the environment.”
“Although it will take some time before this model can go into series production, our engineers will be working full steam to carry out the necessary integration measures and ensure that all components can meet the tough everyday demands required of a luxury long-distance saloon,” says Dr. Thomas Weber, member of the Board of Management of Daimler AG with responsibility for Group Research and Mercedes-Benz Cars Development. “We’ve already got all the key technology we need for such a dream car, which is why I see it being included in the next generation of the S‑Class. The important thing now is that our development work be accompanied by the establishment of a full-coverage infrastructure that will allow the potential of this innovative drive system to be fully exploited.”
The electrical drive components of the Vision S 500 Plug-in HYBRID demonstrate the versatility of Mercedes-Benz’ intelligently organised set of hybrid systems, which has a widely scalable range of performance. The hybrid module’s design does not differ much from the compact, disc-shaped 15-kW electric motor of the S 400 HYBRID, even though it is three times as powerful. As a result, the hybrid module can be elegantly incorporated into the housing of the 7G-TRONIC seven-speed automatic transmission, allowing this model variant as well as the S 400 HYBRID to retain the S‑Class’ spacious interior. Future model generations will orient themselves on this system architecture.
Whereas the extremely compact lithium-ion battery in the S 400 HYBRID (0.9 kWh) can be housed in the vehicle’s engine compartment, the significantly higher-performing lithium-ion unit in the Vision S 500 Plug-in HYBRID (over 10 kWh) requires more installation space. The battery is located behind the rear seats in the boot. The lithium-ion battery’s location above the rear axle provides crucial benefits, since it ensures that the vehicle has a balanced weight distribution and that the petrol tank remains adequate for long-distance cruising. In addition, the protected position of the tank ensures it is as safe as possible during crashes.
Additional clutch decouples the hybrid module and combustion engine
In accordance with the modular concept, the powertrain design for the Vision S 500 Plug-in HYBRID is basically the same as that for the S 400 HYBRID. One system-specific attribute is the presence of an additional clutch integrated between the combustion engine and the electric motor. This device decouples the two components in the pure electric drive mode, thereby ensuring the highest level of efficiency in the latter. Moreover, because it is fully integrated into the vehicle’s converter housing, the clutch does not take up any additional space.
Electrical outlet as a filling station: Powerful plug-in battery
Another key difference between the S 500 Plug-in HYBRID and conventional hybrids involves the plug-in battery, which can be charged at charging stations, thereby enabling the S 500 Plug-in HYBRID to travel up to 30 kilometres on electric power. The rapid charge cycle takes less than 60 minutes with a charging capactiy of 20 kW. A standard charge cycle at a conventional household socket with 3,3 kW takes about four-and-a-half hours to recharge a completely discharged battery.
The model is also equipped with a compact onboard charger: Housed behind the side boot wall, this unit controls the recharging process and is protected against short circuits, voltage reversal, and voltage surges. The charging system also protects the battery by monitoring voltage, the charging level and charging time. The total weight of the electrical components in the current experimental vehicle is 215 kilograms, whereby the lithium-ion battery weighs approximately 130 kg. That’s much less than a conventional NiMH battery with the same capacity, as the weight of such batteries ranges from 180 – 200 kg.
The vehicle’s hybrid module also provides additional energy when the car is in motion through regenerative braking – the recovery of energy when braking. Here, the clutch enhances efficiency as well, as it enables complete energy regeneration without engine drag losses.
Range of up to 30 kilometres with all-electric driving
The high-performance battery and the 44 kW/60 hp hybrid module enable the vehicle to drive up to 30 kilometres purely on electricity. That is completely sufficient for many trips within cities, where the Vision S 500 Plug-in HYBRID is quick and very comfortable without producing any local emissions. The petrol engine automatically adds its power to that of the electric motor when travelling at high speeds or driving up steep inclines. Before closing the clutch in such cases, the vehicle electronics synchronises the engine speed with the hybrid module’s rotational speed so that the engine is activated extremely smoothly without the driver noticing.
What’s more, the hybrid module’s sophisticated interplay with the combustion engine enables numerous additional functions that positively impact fuel consumption, emissions and vehicle agility. Like the system employed in the
S 400 HYBRID, the hybrid module in the Vision S 500 Plug-in HYBRID also comes with the ECO start/stop function. This feature also enhances safety and driving pleasure because of its boost effect, which has the electric motor providing powerful support to the combustion engine during the high-consumption acceleration phase. This system has already proved its practical viability in a slightly different configuration in the Mercedes-Benz Sprinter.
Extensive electronic safety and control components
The lithium-ion battery not only serves as an energy storage device for the electric motor in the S 500 Plug-in HYBRID; it is also linked via a DC-DC converter to the 12-volt on-board network, which provides power to standard consumers such as the headlamps and various comfort devices. To ensure a consistently high level of electrical efficiency, the voltage transformers are water-cooled via an additional low-temperature circuit.
Special power electronics are required for operating the three-phase AC electric motor in the high-voltage direct current grid, and the inverter for this task is housed in the engine compartment. Because the power electronics system itself is heated by the electric current thus created, it too is integrated into the low-temperature cooling circuit. Mercedes-Benz employs standardised components for the power electronics system as well, enabling them to be efficiently combined with different electric motors and battery types across all model series.
On the road to plug-in hybrids: Diesel-hybrid concepts
An important milestone on the road to plug-in hybrids is the recently unveiled Vision E 300 BlueTEC HYBRID diesel hybrid. Like the S 400 HYBRID and the Vision S 500 Plug-in HYBRID, it is based on the Mercedes-Benz modular hybrid concept. This near-series vehicle study combines a new 2.2-litre, four-cylinder diesel engine with the 15 kW/20 hp hybrid module that is also used in the S 400 HYBRID, but which here also enables pure electric driving. This drive system configuration enables the Vision E 300 BlueTEC HYBRID to travel 100 km on only 4.5 litres of fuel (preliminary value). This corresponds to CO2 emissions of 119 grams per kilometre with an output of 165 kW/224 hp and superior torque of
580 – 600 newtonmetres (combined in both cases), more or less the same performance as today’s six-cylinder diesel engines. Exhaust gas treatment is handled by the combination of an oxidizing catalytic converter, a diesel particulate filter and BlueTEC mit AdBlue® injection. The Vision E 300 BlueTEC HYBRID thus also has the potential to meet the world’s most stringent emission standards.

*preliminary values
Mercedes-Benz today has again detailed one member of their modularly constructed electric car family– the Mercedes BlueZERO E-CELL PLUS. Based on the BlueZERO E-CELL (one of the models unveiled late last year that’s driven only by a battery-powered electric drive), the BlueZERO E-CELL PLUS features the same battery powered electric motor but adds a compact 50kW three-cylinder turbocharged petrol engine. As a result, the BlueZERO E-CELL PLUS boasts an operating range of up to 600 km, whereas the BlueZERO E-CELL notes an operating range of 200 km.
In terms of operation, the BlueZERO E-CELL PLUS features a rapid charging option with a capacity of 20 kW, enough power to allow for a 50 km cruising range in about 30 minutes. To achieve full electric charge, a little over an hour is needed, which will then allow the BlueZERO E-CELL PLUS to achieve its maximum range of 100 km (using the electric drive only). Charging time with a standard charge cycle at a conventional household outlet with 3,3 kW is approximately 6 hours.
Speaking briefly about the new concept, Prof. Herbert Kohler, Head of E-Drive and Future Mobility and also Chief Environmental Officer at Daimler, notes: "The Concept BlueZERO offers a triple demonstration of the technical maturity of alternative drive systems from Mercedes-Benz. Electric vehicles with battery electric or fuel cell drive systems will not truly be on an equal footing with today’s combustion engine drive systems until the customers are confident that there is a sufficient infrastructure of electricity and hydrogen refueling stations."
Mercedes-Benz is launching its first series-produced fuel cell car on the road: the new B‑Class F-CELL. The environmentally friendly electric car has better a performance similar to than a 2,0-litre petrol car and is fully suited for everyday driving. The zero-emission drive system consumes the equivalent of 3.3 litres of diesel per 100 kilometres in the NEDC (New European Driving Cycle). Production of the B‑Class F-CELL will commence in late 2009 with a small lot. The first of around 200 vehicles will be delivered to customers in Europe and the USA at the beginning of next year.
The new fuel cell vehicle offers everything that people expect from a Mercedes-Benz: High comfort and safety as well as no reduction in interior space and boot capacity. Customers will not have to sacrifice any driving pleasure either, because the electric motor has a peak performance of 100 kW/136 hp and a maximum torque of 290 Nm, which is available from the first rotation. 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. Despite these qualities, the zero-emission fuel cell drive consumes the equivalent of only 3.3 litres of diesel fuel per 100 kilometres (NEDC). Thanks to its great range of about 400 kilometres and short refuelling times of around three minutes, the B‑Class F-CELL ensures local zero-emission mobility even for long stretches.
“2009 is the year in which we are establishing further milestones where sustainable mobility is concerned. The B-Class F-CELL is taking on a pioneering role as the world’s first fuel cell powered automobile to be produced under series production conditions”, says Dr. Thomas Weber, Member of the Board of Management of Daimler AG, responsible for Group Research and Development for Mercedes-Benz Cars.
The vehicle’s technological heart is the new generation of the compact, high-performance fuel cell system, in which gaseous hydrogen reacts with atmospheric oxygen at 700 bar to generate a current for the electric motor. The fuel cell system of the B‑Class F-CELL has a very good cold-start capability even at temperatures as low as minus 25 degrees Celsius. The drive system was completely newly developed versus the F-CELL A-Class presented in 2004, with Mercedes-Benz engineers achieving considerable improvements in output, torque, operating range, reliability, starting characteristics and comfort. The B-Class F-CELL now offers driving pleasure and day-to-day suitability at Mercedes level – without local emissions.
As in hybrids with combustion engines, the fuel-cell car uses a lithium-ion battery with an output of 35 kW and a capacity of 1.4 kWh to boost power and recover braking energy. Lithium-ion technology offers several advantages over conventional batteries, including compact dimensions, high performance, great recharge efficiency and a long service life.
The B‑Class F-CELL employs the unique sandwich floor architecture that is well-known from the A- and B-Class. The advantage of this design is that the drive components are located in the sandwich floor, where they are protected and don’t take up much space so that the vehicle’s interior remains fully usable and a boot capacity of 416 litres is available.
The B-Class F-CELL does not need to fear comparison where equipment is concerned either. Eye-catching features include a bonamite silver paint finish and exclusive light-alloy wheels in a 10-spoke design. In the interior, leather upholstery, seat heating, automatic climate control and the COMAND-system, as well as other features, continue to ensure a high level of comfort.
Same level of safety as in other Mercedes cars
No matter what the conditions, the operational reliability of the B‑Class F-CELL is of the same high level as in Mercedes vehicles with conventional combustion engines. The B‑Class F-CELL’s integrated safety concept takes the specific characteristics of the innovative drive system into account. The concept incorporates the expertise from the many years of experience Mercedes-Benz has had with fuel cell drives and high-voltage applications. Mercedes engineers have tested and optimised the drive-specific components’ safety in more than 30 additional crash tests.
Network of filling stations required for car’s widespread use
With more than 100 test vehicles and a combined total of over 4.5 million kilometres of trial testing, Daimler and Mercedes-Benz have the most extensive experience with fuel cell vehicles of any manufacturer worldwide. The B‑Class F-CELL is further testimony of this technology’s high level of development for automotive use. However, a comprehensive network of hydrogen filling stations still has to be set up before locally zero-emission driving can become a widespread reality. To make this possible, Daimler is cooperating with government authorities, energy utilities and oil companies in joint projects in places such as Hamburg, Stuttgart and California.
Mercedes-Benz views the development of electric cars with battery and fuel cell drives for local zero-emission driving as a means of supplementing vehicles with high-tech internal combustion engines. Advanced diesel and petrol engines will remain important for automotive applications for a long time to come – not only for individual mobility in passenger cars – especially over long distances – but, more importantly, for freight transport in trucks. Electric vehicles, on the other hand, will increasingly be used in urban transport.
Following in the tradition of its non-hybrid S-Class brethren, the new Mercedes S400 HYBRID has been awarded an environmental certificate by the technical inspection authority TÜV Süd. Other Mercedes models that have received the award include the A-, B-, C-, E- and GLK-Class models.
To arrive at their final decision, technical inspection authority TÜV examined more than 40,000 individual processes, all of which helped went towards the construction of an eco-profile for the model. In addition, TÜV examiners then assessed both the production and eventual recycling/disposal of the model, with this analysis factoring into the final verdict as to whether or not the environmental certificate would be awarded.
In the end, taking the entire lifecycle into consideration (namely production, operation for 300,000 kilometres and recycling/disposal), the S 400 HYBRID produces 18 percent lower CO2emissions than the comparative model. This saving per vehicle corresponds to roughly 1.6 times the annual per capita emissions of the average European*. The lower requirement for energy resources caused by the lower fuel consumption during the operating phase leads to a 17-percent reduction in the primary energy requirement, or around 7000 litres of petrol.
The 2009 Mercedes-Benz S-Class: Pacemaker in automotive development
After four years in production and sales of 270,000 units, Mercedes-Benz is now presenting the 2009 S-Class. With an even more dynamic design, even more comfort and pathfinding innovations, this extensively updated new series of the world’s most successful luxury saloon is reiterating its claim to be the standard for automotive progress. Technological highlights include the world’s first series-production hybrid drive system with a lithium-ion battery in the S 400 HYBRID, which makes this flagship Mercedes-Benz model the world’s most economical luxury saloon with a petrol engine. Its fuel consumption of 7.9 litres per 100 kilometres corresponds to carbon dioxide emissions of just 186 grams per kilometre. This makes the new S 400 HYBRID the “CO2 champion in the luxury class”
In addition the engine range includes eight up-to-date petrol and diesel units, which generate the same, high output as in the preceding series but require up to seven percent less fuel. The high safety standard typical of the S-Class is further improved by a unique combination of new camera and radar based driver assistance systems, with innovations such as Speed Limit Assist, ATTENTION ASSIST drowsiness detection and Adaptive Highbeam Assist. More agility and driving enjoyment is ensured by Direct-Steer and modified Active Body Control with crosswind stabilisation for the eight and twelve-cylinder models. The new luxury saloon will be in the showrooms of Mercedes-Benz’s own-retail outlets and authorised dealerships from June 2009.
With 270,000 units sold since its market launch in autumn 2005, the W 221-series S-Class is the world’s most successful luxury saloon. Since 1951, when the Model 220 founded the lineage of the S-Class, Mercedes-Benz has sold around 3.3 million units of this model series. Dr. Dieter Zetsche, Chairman of Daimler AG and CEO of Mercedes-Benz Cars: “The S-Class is the worldwide market leader. Thanks to innovative technology, first-class comfort and trailblazing safety systems, the flagship model from Mercedes-Benz is seen as a pioneer in automotive development.”
S 400 HYBRID: the world’s most efficient petrol-engined luxury saloon
The 2009 S-Class likewise leads the field in automotive development. Mercedes-Benz is underlining this claim to leadership with the new S 400 HYBRID, the world’s first series-production vehicle to be equipped with a hybrid drive system using a lithium-ion battery. This is a pioneering step by Mercedes-Benz on the way to the electrification of the automobile. The combination of a further developed V6 petrol engine and a compact hybrid module also makes the S 400 HYBRID the world’s most efficient luxury saloon with a petrol engine. The combined New European Driving Cycle (NEDC) fuel consumption is only 7.9–8.1 litres per 100 kilometres. This results in the world’s lowest CO2 emissions in this vehicle class, at just 186 – 189 grams per kilometer.
These figures are accompanied by a truly superior performance potential: the modified 3.5-litre petrol engine develops 205 kW/279 hp, while the electric motor generates 15 kW/20 hp and a starting torque of 160 Nm. The combined output is therefore 220 kW/299 hp, with a combined maximum torque of 385 newton metres.
The Mercedes-Benz S 400 HYBRID is based on the S 350, and features an extensively modified drive train. This encompasses a further development of the 3.5-litre V6 petrol engine, an additional magneto-electric motor, the 7G-TRONIC seven-speed automatic transmission specially configured for the hybrid module, the necessary operating and control electronics, the transformer and a high-voltage lithium-ion battery. The hybrid module also has a convenient ECO start/stop function, which automatically switches the engine off when the vehicle stops – for example at traffic lights.
The lithium-ion battery stores recovered kinetic energy
When the vehicle is braked the electric motor acts as a generator, and is able to recover braking energy by a process of recuperation. Working in finely tuned partnership, the electric motor supplements the braking effect of the combustion engine and the wheel brakes to deliver a smoothly progressive braking action. The recuperated energy is stored in a compact yet highly efficient lithium-ion battery in the engine compartment, and made available when required. This complex system is managed by a high-performance control unit, which is likewise located in the engine compartment.
Major advantages over conventional nickel/metal hydride batteries include a higher energy density and greater electrical efficiency combined with more compact dimensions and a low battery weight. Thanks to space-saving installation in the engine compartment, the boot capacity and generous interior dimensions remain unchanged.
Efficient diesel and petrol engines
In addition to the trailblazing hybrid drive unit of the S 400 HYBRID, the 2009 S‑Class is available with a choice of eight engines: two diesel units and six petrol units with six, eight and twelve cylinders. By means of specific aerodynamic fine-tuning, tyres with a lower rolling resistance and modifications to the steering, fuel pump and 7G-TRONIC automatic transmission, Mercedes-Benz developers have been able to reduce both fuel consumption and CO2 emissions by up to seven percent.
With diesel fuel consumption of up to 7.6 litres per 100 kilometres and CO2 emissions of 199-201 grams per kilometre, the S 350 CDI BlueEFFICIENCY (173 kW/235 hp) likewise boasts outstanding figures for the luxury class. Mercedes-Benz achieves this exemplary efficiency with a tailor-made BlueEFFICIENCY package, which also includes closed underbody panelling and decoupling of the 7G-TRONIC automatic transmission at standstill.
The 3.0-litre diesel engine is also used in the S 350 CDI 4MATIC. The second diesel variant is the eight-cylinder S 450 CDI (235 kW/320 hp) with a displace-ment of 4.0 litres. The range of petrol engines comprises the six-cylinder S 350/ S 350 4MATIC (200 kW/272 hp) with a displacement of 3.5 litres and the two eight-cylinder units in the S 450/S 450 4MATIC (250 kW/340 hp; displacement 4.7 litres) and S 500/S 500 4MATIC (285 kW/388 hp; displacement 5.5 litres). The flagship model is still the S 600 with the 380 kW/517 hp twelve-cylinder biturbo unit), which accelerates the luxury saloon to 100 km/h in 4.6 seconds. The Mercedes-AMGhigh-performance contributions to the range are the S 63 AMG with its 386 kW/525 hp V8 engine (displacement 6.2 litres) and the S 65 AMG with a 459 kW/612 hp twelve-cylinder engine (displacement 6 litres).
The Mercedes-AMGhigh-performance contributions to the range are the S 63 AMG with its 386 kW/525 hp V8 engine (displacement 6.2 litres) and the S 65 AMG with a 450 kW/612 hp twelve-cylinder engine (displacement 6 litres).
Unique combination of driver assistance systems
A combination of ultra-modern assistance and protection systems turns the S‑Class into an “intelligent” partner that can see, feel, respond reflexively and act independently to prevent accidents or mitigate their effects. For the first time Mercedes-Benz also uses cameras in these systems – these are able to look well ahead, monitor the car’s surroundings and interpret critical situations. One example is the optional Adaptive Highbeam Assist. This system recognises oncoming vehicles or vehicles ahead with their lights on, and then controls the headlamps to ensure the best possible beam range without dazzling other road users.
As a new feature the Night View Assist Plus with infrared camera is now equipped with a special pedestrian detection function: as soon as the system detects pedestrians on the road ahead, they are highlighted on the display to make them more readily noticeable.
Lane Keeping Assist is another system that “looks ahead” for even safer driving. The camera on the inside of the windscreen is able to recognise clear lane markings by evaluating the contrasting images of the road surface and the markings. If the vehicle leaves its lane unintentionally, the driver is warned by short vibrations of the steering wheel. Unlike conventional systems of this kind, the Mercedes system is able to evaluate the driver’s activities as well, and can reliably ascertain whether the car is leaving its lane intentionally or not. There is therefore no warning if the driver e.g. accelerates before overtaking or joining a motorway, brakes heavily or enters a bend.
The images supplied by the windscreen camera are also used by the new, optional Speed Limit Assist, which recognises speed limit signs in passing and shows the relevant speed limit in the central display (standard for S 600).
Drowsiness detection on the basis of more than 70 parameters
Thanks to an innovative technology the 2009 S-Class has a very sensitive antenna for the attention level of its driver, and can warn him in time when he becomes drowsy. The drowsiness detection system ATTENTION ASSIST continuously monitors more than 70 different parameters. Once the evaluation electronics recognise the steering behaviour pattern that typically indicates the onset of drowsiness on the basis of information from the highly sensitive steering angle sensor, a warning signal is sounded and “ATTENTION ASSIST. Break!” appears in the instrument cluster. Attention Assist is standard equipment* in the 2009S-Class.
* not for S 400 HYBRID
“Electronic crumple zone” for maximum occupant protection
Mercedes-Benz has also improved the long and medium-range radar used by Brake Assist (BAS) PLUS and DISTRONIC PLUS proximity cruise control.
Mercedes-Benz also offers another radar based system for the S-Class in the form of the PRE-SAFE® brake. If the driver is distracted and fails to recognise the immediate danger of a rear-end collision, or the warning signal of an assistance system, this system can intervene and brake the vehicle independently. The 2009 S-Class makes use of the latest development stage of this safety system: if the driver fails to react even after automatic, partial braking action, the PRE-SAFE® Brake activates the maximum braking pressure around 0.6 seconds before what is now recognised as an unavoidable accident – an emergency braking action that can significantly mitigate the severity of the impact. The PRE-SAFE® Brake therefore acts as something like an “electronic crumple zone”.
New: Active Body Control reduces the effect of a crosswind
The S-Class also meets the highest expectations with respect to driving dynamics and agility. This is in part due to Direct-Steer, with a steering ratio that varies with the steering angle, and modified Active Body Control (ABC) with crosswind stabilisation (optional for the eight-cylinder models with rear-wheel drive, standard for S 600). For this purpose ABC uses the yaw rates and lateral acceleration sensors of the Electronic Stability Program ESP® to vary the wheel load distribution via the ABC spring struts within milliseconds, depending on the direction and intensity of the crosswind. This enables the effects of crosswinds to be largely compensated.
Extra safety at the physical limits, as well as even more agility, is provided by the Torque Vectoring Brake in the 2009 S-Class – targeted, one-sided braking intervention at the inside rear wheel when cornering. The result is a defined turning moment around the vehicle’s vertical axis, which means that the car turns into the bend precisely and without any loss of handling dynamics. This Torque Vectoring Brake function is standard equipment in the 2009 S-Class.
Powerful and self-assured presence
The modified design of the 2009 S-Class reflects the effortless superiority and power of the S-Class Saloon. It is characterised by the more pronounced arrow-shape of the radiator grille, plus a new front bumper with a discreet light-catching contour and a chrome strip below the cooling air intakes. The headlamps have bi‑xenon technology as standard.
An even more dynamic look is ensured by the LED Light package with its striking LED arrays for daytime driving lights, indicators and driving lights (standard for S 400 HYBRID and S 600). They lend an unmistakable day-and-night design to the front end. The rear end is characterised by tail lights in a new design, with horizontal, white light rather than the previous inserts in the vehicle colour. Here too, a total of 52 LEDs arranged in a curved design form an unmistakable light signature.
Mercedes-Benz also makes more use of light as a styling element in the interior. In future customers who specify the optional ambient lighting (standard for S 400 HYBRID and S 600) have a choice between three lighting moods: solar (amber), neutral (white) and polar (ice-blue).
State-of-the-art multimedia technology
In line with its serene character and claim to be a technological trendsetter, the 2009 S-Class also sets standards where onboard infotainment is concerned. As a world first, and on request, Mercedes-Benz will equip its flagship model with the new SPLITVIEW technology for the COMAND control and display system centrally located in the centre console. This innovative display concept allows the driver and front passenger to view different content simultaneously on one and the same screen. While the driver e.g. uses the map-based navigation system, the front passenger can be watching the latest film on DVD.
Mercedes-Benz has also extended the standard control and display system COMAND with additional functions, for example an SD memory card slot. Other new features include a Bluetooth® interface, which wirelessly connects a mobile phone to the standard onboard hands-free system, and a USB interface. These enable customers to export saved data and import them into any other S-Class. It is also possible to transfer navigation data to another vehicle. As an optional extra Mercedes-Benz also offers a media interface – a universal interface in the glove compartment for mobile audio devices like an iPod® and USB stick also with AUX input (standard for S 400 HYBRID and S 600).
The optionally available COMAND APS (standard for S 400 HYBRID and S 600) is additionally equipped with a Europe-wide navigation system whose data are stored on a 40 GB hard disc. This allows particularly fast route calculation. The high level of navigating convenience is also aided by the detailed three-dimensional map display.
Musical entertainment is provided by a radio, a CD/DVDplayer with MP3 function, an equalizer with speed-dependent volume control and the MUSIC REGISTER with a 7.2 GB hard disc which stores around 2500 digital music files in the MP3, AAC or WMA format.
The system recognises music files played on CD, DVD or from the MUSIC REGISTER using its stored Gracenote® database, and shows the title, album and performer in the colour display. The new Music Search function enables S-Class drivers and passengers to search SD memory cards, USB sticks, CDs and DVDs for specific music titles and performers. COMAND APS also includes the latest-generation LINGUATRONIC voice-operated control system, which operates the navigation, telephone and audio devices by whole-word commands. This has the advantage that the driver no longer has to spell out his commands. To enter a destination, select a radio station, choose a title from the MUSIC REGISTER or access a contact in the phone directory, he only needs to say what he wants.
Mercedes-Benz has also increased the range of rear seat entertainment functions in the 2009 S-Class. As standard equipment, passengers in the rear now have a remote control unit which enables all the audio and telematics functions of COMAND to be operated, plus access to external devices via the Media Interface. Mercedes-Benz also offers a Rear Seat Entertainment package with two eight-inch displays on the rear surfaces of the front seat head restraints, two wireless headphones and a separate CD/DVD player with connections for external audio and video devices.
The surround sound system with “Logic 7” technology developed by Mercedes-Benz together with the audio specialists Harman Kardon® delivers an outstanding performance with three-dimensional sound as a natural 360-degree musical experience for all passengers.
Interior: carefully selected materials and first-class finishing
The multifunction steering wheel of the S-Class has also been modified by the Mercedes-Benz designers: in future the rim and airbag module are lined wth soft nappa leather as standard. The new, flatter airbag module also lends a sporty touch to the multifunction steering wheel.
When choosing the interior, S-Class customers now have even more scope for their personal preferences. A total of five different types of wood trim provide perfectly coordinated material and colour concepts to suit personal tastes.
To make the decision-making process easier, Mercedes-Benz designers have developed three new interior combinations for the colour scheme: alpaca grey/basalt grey, cashmere beige/savanna beige and chestnut brown/black. Together with an all-black interior for the comfort-oriented business saloon and the well-proven combination of sahara beige/black, this produces a total of five tasteful interior design options. In addition to high-grade fabrics, leather upholstery in three qualities is available as an option.
Yes, ladies and gentlemen, after taking a little more than a week off, we are indeed back this fine April morning, once again bringing you the latest in Mercedes-related news and entertainment. Unfortunately, it was an unexpected trip paired with an equally unexpected lack of Wi-Fi access that caused the abrupt article hiatus, but not to worry, as both myself and the rest of the staff are back from their spring vacations and ready to get to work.
As is the case anytime a vacation is enjoyed, we’ve got plenty of work to catch up on, so rather than commenting on each of the various press releases we’ve missed, we’re going to bring you the straight corporate content in an effort to get you caught up as quickly as possible. Once we’ve caught up on our backlog, however, we will once again return to the trademark wit you’ve all come to know and love.
But enough of my rambling – let’s get to the Mercedes content, starting with the brand-new, slightly revised and somewhat awkward looking 2009 Mercedes-Benz S-Class. Keep scrolling for a number of photos and a lengthy press release detailing what to expect from the latest iteration of the endearing S-Class.
Mercedes-Benz is showing the way ahead in environmentally responsible electromobility by presenting its near-series Concept BlueZERO at the North American International Auto Show in Detroit. 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 three 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 BlueZERO concept cars also set standards in terms of lightweight design, interior layout, and body form.
“The flexible BlueZERO concept allows electromobility for every requirement and highlights the fact that Mercedes-Benz is the world’s only car manufacturer to already have in place all the key technologies for electric cars offering full everyday practicality”, says Dr. Dieter Zetsche, Chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz Cars.
The BlueZERO principle: flexible design, compact exterior, and 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 meters 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 liters 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, Concept BlueZERO 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 with respect 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, for example.
Modular design assures flexibility and efficiency
“Our modular system allows different drive configurations for every customer requirement”, says Dr Thomas Weber, the member of the Daimler AG Board of Management responsible for corporate research and development at Mercedes-Benz Cars. “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 optimized 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.”
All three BlueZERO models feature front-wheel drive, which is typical for this class of car. The Mercedes engineers have put together a modular system comprising several flexibly combinable drive components. These include state-of-the-art liquid-cooled lithium-ion batteries with a storage capacity of up to 35 kWh and the compact electric motor with a maximum output of 100 kW (continuous output 70 kW), which develops a peak torque of 320 Nm. All three variants accelerate from 0 to 100 km/h in less than 11 seconds. Their top speed is electronically limited to 150 km/h in the interests of optimal range and energy efficiency.
Electric drive systems with a range of 100, 200, and well over 400 kilometers
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 kilometers 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 kilometers 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.
At the rear, the BlueZERO E-CELL PLUShas the same 1.0-litre turbocharged gasoline 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 kilometers is possible on a single tank. The purely electrical, locally emission-free range is up to 100 kilometers. The BlueZERO F-CELLwith fuel-cell drive achieves a range of well over 400 kilometers 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 Concept BlueZERO at first glance.
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 optimized, while low-friction tires are fitted to 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 Concept BlueZERO is characterized 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-gray tailgate is made completely from lightweight but highly robust Lexan, allowing a view of the aluminum 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.
“It was very important for us to ensure that the guiding Mercedes-Benz principle of ‘Fascination and Responsibility’ was clearly reflected in the design of the Concept BlueZERO”, says Mercedes-Benz design chief Gorden Wagener. “This is yet another clear statement that environmental awareness and driving pleasure will continue to go together in our vehicles in the future. We want people to realize at first sight that the Concept BlueZERO is definitively not a lesser option.”
The Mercedes-Benz designers have emphasized this aspiration by introducing paint finishes in three new ALU-BEAM colors. Each of the three variants makes its individual mark: the BlueZERO E-CELL is painted in 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.
Extended version
Mercedes-Benz Concept BlueZERO: three-fold proof of the everyday practicality of zero-emission vehicles
Current challenges such as growing worldwide mobility requirements, declining crude oil reserves, and increasingly stringent exhaust emission regulations are making the electric car more and more a focus of public attention. Thanks above all to major advances in battery technology, electric drive is seen as a promising answer to the question of how individual mobility can be made sustainable.
Battery-electric drive systems offer a wealth of advantages in this respect: they provide a high level of torque, are compact and quiet, run extremely efficiently and with zero local emissions, and they operate without the need for fossil fuels. However, it is not currently possible to fulfill all mobility requirements with a single electric vehicle concept. Those who drive predominantly or even exclusively in urban areas do not place as much emphasis on vehicle range but very much like the idea of lower noise levels and emissions. For such customers, a battery-electric vehicle is an attractive solution.
Those who also wish to cover long distances on country roads and motorways combined with low noise levels, no local emissions, and short refueling times have a viable alternative in the shape of the fuel-cell electric vehicle. This technology clearly shows the way ahead in terms of sustainable mobility after the “crude oil age” but requires a hydrogen-fuel-supply infrastructure. The beneficial combination of maximum range, fast energy storage on board from an existing infrastructure, and noiseless and locally emission-free mobility in urban areas is offered by a battery vehicle with range extender.
Concept BlueZERO: modularity assures optimal everyday practicality
The sandwich-floor architecture and the modular design allow three different drive configurations that are able to meet an extremely wide range of different requirements. Measuring 4.22 meters in length, 1.89 meters in width and 1.59 meters in height, the extremely compact BlueZERO concept offers decisive design advantages over electric cars based on conventional vehicle platforms and designed only for use in combination with internal combustion engines.
Interior space is retained in full. As the energy accumulators/generators are integrated into the spacious sandwich floor, no compromises are necessary with respect to passenger space, luggage capacity, or variability.
The powertrain technology located in the sandwich floor and integrated directly at the front axle assures a low centre of gravity and, consequently, extremely reliable and agile handling.
Crash safety is of the extremely high standard associated with Mercedes thanks partly to the housing of the powertrain components between the axles.
Furthermore, all three BlueZERO electric cars are highly suitable for electromobility in urban areas on account of their compact dimensions, easy entry and exit, raised sitting position, and optimal all-round visibility. All of which makes Mercedes-Benz the first and, to date, only car manufacturer in the world to offer three optimal solutions that meet all customer electromobility requirements.
Intelligent sandwich platform assures the highest possible level of safety
Featuring a modified version of the sandwich-floor platform, the BlueZERO concept sets standards for the electric car sector in all areas relevant to day-to-day motoring. The best possible crash safety is assured, since almost all of the drive components are housed within the sandwich floor, that is to say in the protected area between the axles.
Typically for this class of car, all three versions of the Concept BlueZERO are front-wheel drive models with an electric motor at the front axle. The batteries are located in the center of the vehicle floor behind this, in a position which protects against intrusion in the event of a frontal or rear impact, since the energy accumulators are located outside of the body’s impact and deformation zones. Furthermore, the extremely robust construction of the sandwich floor can offer a high level of protection for both the battery and the occupants, even in the event of a side collision. This advantage is also of economic benefit, since the battery is the largest cost factor in electric drive systems. Consequently, if the battery remains undamaged in an accident, the follow-up costs are reduced considerably. By virtue of its proven nutshell effect, the sandwich floor is the safest place for housing the still relatively expensive energy accumulators.
Room for five occupants and luggage thanks to highly efficient use of space
This clever sandwich construction also has obvious advantages where packaging is concerned: locating the drive modules in an underfloor position makes it possible to retain all of the passenger and luggage space in this 4.22-meter long five-seater, with no restrictions whatsoever. In the purely battery-powered BlueZERO E-CELL, for example, up to two of the lithium-ion battery packs developed by Mercedes-Benz can be accommodated in the sandwich floor.
In addition to exemplary safety and unrestricted everyday practicality, the BlueZERO models have further strengths that are by no means the norm for electric cars, namely agility and driving enjoyment. This is in large measure due to the low centre of gravity, another benefit of the low installed position within the sandwich floor, and the front axle suspension. In combination with uncompromising attention to centered masses, this results in outstanding roadholding and handling agility.
Modular drive concept for individually configured electric vehicles
Mercedes-Benz will present two BlueZERO variants at the 2009 NAIAS show in Detroit: the BlueZERO E-CELL as a purely battery-powered vehicle and the fuel-cell version, the BlueZERO F-CELL – both of which are emission-free in local operation. Mercedes-Benz development engineers are also working on a third version with a range extender, the BlueZERO E-CELL PLUS. This is additionally equipped with a compact internal combustion engine as a generator that produces power during a journey.
All these models feature battery packs based on the latest lithium-ion technology. This new battery technology has decisive advantages over conventional battery types, among them very compact dimensions, significantly higher performance, excellent reliability, and a long operating life. The identical components used in the modular system also include the compact, permanent-magnet synchronous electric motor, which operates at a maximum of 13,280 rpm. It develops a peak output of 100 kW and a continuous output of 70 kW. Its peak torque is 320 Nm, while the continuous torque is 180 Nm. The maximum torque is available from the first revolution of the electric motor and exceeds the figure achieved by a current V6 gasoline engine at 2500 rpm.
BlueZERO E-CELL: agile, quiet and locally emission-free
The BlueZERO E-CELL is equipped with a lithium-ion battery with a capacity of 35 kilowatt hours (kWh). The liquid-cooled high-voltage cells have an operating voltage of 240 to 426 V. With this battery, the BlueZERO E-CELL has an operating range of up to 200 kilometers. Recharging the empty battery takes three to four hours. The BlueZERO E-CELL accelerates from zero to 100 km/h in less than eleven seconds and, in the interests of optimal range and energy efficiency, has an electronically limited top speed of 150 km/h.
BlueZERO F-CELL: emission-free driving on long journeys with the fuel cell
The new-generation fuel cell used in the BlueZERO F-CELL is more compact and – with a maximum output of 90 kW (continuous output 80 kW) – also more powerful than its predecessor. It can be cold-started at temperatures down to minus 25 degrees Celsius and also has the benefit of short refueling times.
On the road, the BlueZERO F-CELL assures a high standard of dynamic handling, yet this family-friendly compact car consumes just 2.9 liters of fuel (diesel equivalent) per 100 kilometers. According to the NEDC, the BlueZERO F-CELL is able to cover well over 400 kilometers on one tank of hydrogen.
In the fuel cell version of the BlueZERO, the electric motor, high-voltage battery, and hydrogen tank are likewise positioned beneath the passenger cell to save space. The system uses the most efficient energy source for the current driving situation. When parking or maneuvering at slow speed, for example, the electric motor uses only battery power. When accelerating, energy is provided by both the fuel cell and the battery. When braking, the electric motor acts as a generator and charges the battery. This efficient system therefore makes use of the energy that would be converted into heat during conventional braking and stores it in the powerful lithium-ion battery.
For longer journeys too, Mercedes-Benz sees the fuel cell as one of the key technologies for zero-emission driving. Providing a suitable network of hydrogen filling stations is in place, this technology offers ideal possibilities for sustainable mobility well into the future. The hydrogen-powered fuel cell combines zero emissions with a long operating range, since electrical power is generated on board during the journey. There are no exhaust emissions whatever, and no CO2 is emitted either. The BlueZERO F-CELL emits nothing more than steam. Moreover, a fuel cell drive system is almost twice as efficient as an internal combustion engine.
BlueZERO with range extender: flexible solution with a long range
In the third version, the BlueZERO E-CELL PLUS, the Mercedes engineers combine the electric drive system from the purely battery driven BlueZERO E‑CELL with an additional internal combustion engine that serves as a range extender. The compact 50-kW three-cylinder turbocharged gasoline engine from the smart fortwo charges the battery whilst the car is being driven.
Advantage of the range extender: as with conventionally powered cars equipped with a gasoline or diesel engine, the customer benefits from a significantly longer range (up to 600 km), especially as the BlueZERO E-CELL PLUS can also be quickly and easily refueled at any normal filling station. The customer can therefore be sure that the car is available for use anywhere and at any time. And when an urban area is reached after an overland journey, the driver can continue on their way under electric power alone.
The BlueZERO E-CELL PLUS therefore allows electric mobility at the touch of a button, a particular benefit in densely populated urban areas with environmental zones, toll charges, and other access restrictions affecting cars with internal combustion engines.
The BlueZERO E-CELL PLUS with the range extender clearly highlights the advantages of the sandwich-floor platform: here too, the key drive components are integrated in the underfloor area to save space. The internal combustion engine is installed near the rear axle, in the spare wheel well. Thanks to the range extender, the BlueZERO E-CELL PLUS has a range of up to 600 kilometers, of which 100 kilometers are in locally emission-free electric mode, with no drop in performance. The NEDC fuel consumption is 4.5 liters per 100 kilometers. In conjunction with a plug-in battery and the resulting CO2 bonus, the car emits just 32 grams of CO2 per kilometer.
In addition, the highly efficient modular concept allows further variants to be individually configured. If the system is designed appropriately, the internal combustion engine used as a range extender can also be employed temporarily as a direct drive unit – when driving on country roads, for example. This setup leaves the full battery capacity available for driving in town. Other conceivable variants might be to use the fuel cell as a range extender, or a combination of the fuel cell and plug-in batteries. Thanks to this versatility, the Mercedes-Benz modular electric drive concept is able to cover every conceivable option for electric driving.
Instead of a fuel filler cap, the car features plug-in connectors to EU and US standards for rapid recharging with electrical power. One contact is intended for conventional power cables that fit any household power socket. The second is suitable for connection to public recharging stations.
BlueZERO design: both elegant and functional
Cutting-edge technology is very attractively packaged in all the BlueZERO variants. The future-oriented yet unmistakable Mercedes-style body contours accentuate the progressive nature of the Concept BlueZERO at first glance.
The Mercedes-Benz designers have emphasized this aspiration by introducing paint finishes in three new ALU-BEAM colors. Each of the three variants makes its individual mark: the BlueZERO E-CELL is painted in 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.
Striking design idiom with bionic structures
The striking character lines along the flanks give this compact concept car a very dynamic side line and accentuate its bionic structure. This characteristic feature of the Mercedes-Benz bionic car was adapted and modified for the Concept BlueZERO. These elements lend the body design its dramatic power.
The lower line emerges from the flank in the front doors at the height of the wheel hub, then rises gently to turn steeply upwards and harmoniously continue the body line to the tail lights. This has the effect of stretching the body in visual terms, while suggesting dynamic forward movement despite the comfortable vehicle height. The precisely placed edges break the light to striking effect and lend the BlueZERO a masculine character that is a hallmark of the new Mercedes-Benz design idiom.
Translucent surfaces make the normally concealed technology visible. The light-gray tailgate is made completely from lightweight but highly robust Lexan, allowing a view of the aluminum 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: the luggage compartment and passenger area remain fully usable, since there are no technical components that need to be accommodated here.
Key features at the distinctive rear end of the BlueZERO models include tail lights in the form of a curved “L”, whose flame-like shape add a futuristic touch. In addition, the Mercedes designers have achieved a new-quality light production: four 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. The extremely energy-efficient LED technology offers the same brightness but requires ninety percent less power than conventional lights.
The lenses are held by supports which also serve as direction indicators.
Aerodynamic design with eye-catching effects
The radiator grille with its centrally located star and even more pronounced V‑shape is a striking reinterpretation of the world-famous Mercedes-Benz radiator grille. The excellent aerodynamics of the BlueZERO are partly due to the closed front apron, whose design dispenses with any cooling air intakes. The 20-inch wheels are also aerodynamically optimized. Low-friction tires are fitted to reduce rolling resistance.
Like many other design features, the wheel covers are transparent and allow a view of wheel spokes, which are visually enhanced with three-dimensional light effects. All BlueZERO variants are also equipped with a semi-transparent, lightweight panoramic roof into which solar panels have been integrated. The thin-layer cells used here allow 20 percent of the light into the interior. Given enough sunlight, they generate sufficient electric power to charge cell phones or mobile MP3-players, for example.
Progressive interior design
The interior features an all-new, progressive design idiom: the lines are curved and blend in subtly with the organic surfaces. The Concept BlueZERO is a logical continuation of the bionic design line and is similar to the Mercedes-Benz bionic car. A wealth of structures inspired by nature and modeled based on organic growth can be found in several of the paneling components: in the door stowage areas, the cockpit, the centre console, the load compartment, and the load sill guard.
The array of colored transparent surfaces lends the interior a feeling of lightness. This is enhanced by semi-transparent surfaces whose edges form striking light breaks. This interplay between transparency and edge emphasis contrasts extremely well with the soft design idiom. The suggested fluorescent conductor paths in the center console represent the advent of a future drive technology.
The sporty front seats feature seemingly inserted upholstery and dynamically shaped backrests. The overall impression is one of lightness and litheness, all
of which makes the vehicle interior feel much more open. As a five-seater, the Concept BlueZERO offers the flexibility and functionality of a modern-day compact car.
The material concept is largely based on a tone-in-tone composition enriched by touches of color. By way of example, the belt color and the seam thread in the paneling components establish a link with the car’s exterior, while the leather strip in the seats creates a visual link with the high-quality steering wheel.
Thanks to their surface quality, the materials are highly resistant. The material mix of textiles and plastics combines a high level of value with high-tech appeal.
Concept BlueZERO: a blueprint for efficient electromobility
With the BlueZERO concept studies, Mercedes-Benz provides a very specific outlook on the immediate future of electric motoring. Major components of this modular drive concept will shortly be used in standard-production cars made by Mercedes-Benz. These include the fuel cell drive system, which will enter small-scale production in 2009. In 2010, the first Mercedes-Benz electric car will also be introduced into small-scale production.
Modular design as a strategic guideline
With this intelligently conceived modular system, Mercedes-Benz will also be able to realize tailor-made drive configurations for individual requirements in the electric car sector. For the brand’s clients, this means a wide choice of purpose-made, efficient, and affordable solutions.
The product implementation presented by Mercedes-Benz on its “Road to the Future” is uncompromisingly wedded to the modular design principle: modular drive technologies that can be used individually or in combination depending on vehicle class, operating profile, and customer requirements are a key factor in this.
Modular drive concept also for hybrid vehicles
This particularly applies to hybrid models such as the S 400 BlueHYBRID, which is due to be launched in 2009 as the most economical gasoline-powered luxury saloon and CO2 champion in its class. For its hybrid models with gasoline and diesel engines, Mercedes-Benz has developed a modular system which can be expanded with respect to performance and range of applications.
In the S 400 BlueHYBRID, the hybrid module with its start-stop function, recuperation and boost effect already makes considerable savings possible.
With a suitable configuration, it is also possible to drive under electric power alone with this hybrid module, while the operating range in electric mode depends on the battery capacity.
The plug-in hybrid represents a further step, where the battery can also be charged from the mains in order to increase the electric operating range.
Intelligent drive mix for sustainable mobility
In the view of Mercedes-Benz, there will be no single technology as the ideal solution for sustainable mobility in the future. Instead the company is responding to the varied requirements with equally versatile solutions. The respective advantages of the individual technologies in terms of optimal fuel consumption and emission values are applied in specific application areas. Mercedes-Benz is basing its strategic planning for the future of individual mobility on the following mix of drive systems:
For long-distance operations, sophisticated internal combustion engines with or without a hybrid module will be used, as well as fuel cell powered vehicles.
For rural operations, plug-in hybrids will increasingly be added to the mix.
For urban operations, locally emission-free vehicle concepts with battery and fuel-cell drive systems are considered to be the most suitable.
The electric drive configuration presented in the Concept BlueZERO does full justice to this requirement profile. Mercedes-Benz has conducted intensive research in the field of fuel cell technology since as early as 1991 and, therefore, has enormous experience with electro- mobility. The brand has the world’s largest fleet of fuel cell powered vehicles undergoing client trials, for example.
And in the field of battery-powered vehicles, the company has also gained unrivalled experience from fleet trials involving 100 smart electric drive cars in London. The Concept BlueZERO impressively reflects this in-depth know-how.
Last week we told you that Mercedes was preparing a trio of BlueZERO concept models for the North American International Auto Show in Detroit, each of which featured a distinct alternative power source. In the BlueZERO E-Cell, power came by way of a lithium-ion electric drive; in the BlueZERO E-Cell Plus, a lithium-ion electric drive plus an internal combustion was present; and in the BlueZERO F-Cell, a fuel cell system was the primary means of thrust (their operating ranges varied from 75 miles to just under 450 miles).
This week, Mercedes has confirmed that the three BlueZERO concept vehicles are indeed set to premier at Detroit’s North American International Auto Show, with the three models the latest demonstration of the company’s focus on developing “modular powertrain technologies.” Each are based on the same lightweight sandwich-floor architecture (first introduced on the A-Class and then B-Class some ten years ago), with their goal being to demonstrate how in a single platform, Mercedes already has the ability to offer a varying range of alternative drive technologies based on individual customer requirements.
According to Daimler CEO Dr. Dieter Zetsche: “The flexible BlueZERO concept allows electromobility for every requirement and highlights the fact that Mercedes-Benz is the world’s only car manufacturer to already have in place all the key technologies for electric cars offering full everyday practicality.”
Dr Thomas Weber, the member of the Daimler AG Board of Management responsible for corporate research and development at Mercedes-Benz Cars, adds: “Our modular system allows different drive configurations for every customer requirement. 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.”
Or, to put it simply, Mercedes would like to formally state that they have succeeded in creating a trio of alternatively-powered A-/B-Class models, but in all probability, you won’t be getting your hands on one anytime soon.
For more information regarding the Mercedes-Benz BlueZERO concept vehicles, keep reading for the official press release and photos (click to enlarge).
According to the all-seeing eyes and all-knowing minds at Auto Motor und Sport, Mercedes is on the verge of introducing three new alternatively powered “BlueZero” concept vehicles – a feat they’ll perform at next month’s North American International Auto Show in Detroit (January 11th-25th; get your tickets while they’re hot). Titled the Mercedes-Benz BlueZero E-Cell, the BlueZero E-Plus Cell and the BlueZero F-Cell, the three models make use of a lithium-ion electric drive, a lithium-ion electric drive plus an internal combustion engine and a fuel cell system, respectively.
In the Mercedes BlueZero E-Cell (powered only by a lithium-ion electric drive system, remember), range is expected to be about 75 miles. In the fuel cell powered Mercedes BlueZero F-Cell, range is expected to double, thanks to the electric motor’s ability to act as a generator, thus charging the battery during various stages of operation (much like the S400 BlueHYBRID). And in the BlueZero E-Plus Cell, a rear-mounted three-cylinder turbo petrol engine borrowed from the smart fortwo is rumored to give the part gas, part electric model an operating range of some 372 miles, with another 75 miles on tap operating in purely electric mode.
How this information was derived isn’t clear, but judging by the commonality of Mercedes’ various “leaks,” I’d expect when the North American International Auto Show opens its doors next month the majority of Auto Motor und Sport’s assessments will be spot on.
Time will tell, but in the meantime, keep scrolling to see a number of photos depicting one of the Mercedes BlueZero concept vehicles (click to enlarge), then head over to Auto Motor und Sport where you can check out their full article translated from German for your reading entertainment.
