Mercedes-Benz will unveil two new E-Class Hybrids @ Detroit in 2012

Mercedes-Benz revealed two E-class hybrids on Monday, ahead of their public debut in January at the Detroit auto show.

The gasoline-electric E400 will go on sale in North America later this year.

The first-ever hybrid model in the E-class lineup runs Mercedes’ widely used 3.5-liter V6 gasoline engine with 302 hp and 273 lb-ft, in combination with a brushless electric motor housed within the gearbox casing with 27 hp and 184 lb-ft.

This is sufficient to provide the E400 hybrid, which uses a modified version of the company’s seven-speed 7G-Tronic automatic gearbox to channel power to the rear wheels, with a 0-to-60-mph time of 6.7 seconds and top speed limited to 130 mph.

The E300 Bluetec hybrid will also bow in Detroit. It mates a turbocharged 2.1-liter four-cylinder common rail diesel engine producing 201 hp and 369 lb-ft with the same electric motor used in the E400 hybrid. The powertrain provides the E300 hybrid sedan with 0-to-62-mph acceleration in 7.5 seconds and a top speed of 150 mph.

It uses a host of fuel-saving measures, including optimized aerodynamics, automatic stop/start, brake energy recuperation, a so-called “sailing mode” that decouples the engine from the gearbox on a trailing throttle at speeds up to 100 mph and low-rolling-resistance tires.

Energy for both the E300 and E400 hybrids’ electric motors is supplied by a 0.8-kWh lithium-ion battery that is claimed to provide both cars with an all-electric range of less than a mile at speeds below 35 mph.

Daimler Start Field Test on Wireless Charging of Electric Vehicles

To test feasibility of a inductive charging system, Daimler and Conductix-Wampfler have elaborated the basics for wireless charging of electric vehicles in a research project cofunded by the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (Bundesministerium für Umwelt, Naturschutz und Reaktorsicherheit, BMU). Main target of the project “wireless charging” is a safe, automotive grade charging system with maximum efficiency and minimum weight and package.

High Efficiency

Goal of the field test is to evaluate everyday usability of wireless charging as well as to probe advantages and disadvantages in comparison with charging by plug and cable. As early as a few days into the field test the advantages customer comfort and charging safety by the automated charging process became apparent.

The testing is focused on the basic charging process. Efficiency of the system admittedly still doesn´t match charging by cable, but is with 90 percent already very promising and only slightly beneath cable based solutions, if all components from socket to battery are taken into account.

There was an evaluation of the first “driving-experiences” with study participants who had to “drive onto the optimum charging position”. After two or three exercise runs this could be well achieved supported by parking assistance functions. The system tolerates smaller deviations within the range of a few centimeters without noteworthy loss of charging efficiency or transferable power. Also, the system showed already good results regarding electro magnetic compatibility. It is the task of future engineering work to optimize this as well as to improve efficiency and to develop solutions for a series application.

Technology and Vehicle

The protototypes built within the project on the basis of the B-Class E-CELL with range extender are equipped with an electronic rectifier and a collector coil integrated into the underbody cover. Main components on the infrastructure side are the supplying electronic and the charging coil, which was realized in two variants – as an above ground and beneath ground coil.

Besides the wireless energy transfer other functional aspects are the wireless communication between infrastructure and car, the driver assistance function “driving onto the position above the charging coil”, the automatic start of the charging process and the vehicle identification. In the area between the coils an object detection avoids risks by warmed metal items.

Detailed scientific studies generated the foundation for the first layout of the inductive transfer components with automotive specific requirements and their optimization regarding package and weight. Comprehensive system simulations served to validate the designs.

Conductix-Wampfler has developed all components of the system and could rely during the process on comprehensive experience with inductice power transfer in manufacturing automation as well as on know-how from the wireless charging of electric busses in Genoa and Turin. These are in operation since 2003.

Daimler has defined the functions of the charging system on the car´s side and realized the assistance system for driver support. The system was integrated into two vehicles with range extender, nameplate Mercedes-Benz B-Class E-CELL Plus. The coil integration within the underbody cover of the cars was designed and supplied by Röchling Automotive.

After the prototype vehicles had been built the complete system was mechanically and electrically integrated and taken into operation as a whole. Two inductive charging stations are in the field at the Daimler-Engineering-Location Böblingen-Hulb and are intensively used for the everyday-tests.

Résumé and Outlook

First conclusions confirm the considerable gain of comfort in comparison with cable based charging and that inductive charging is suitable in principle. The potential optimization regarding package, weight and integration in future vehicle model lines is identified and will accordingly be further developed.

At the same time an evaluation is done on new common projects with potential inductive charging applications in small commercial vehicles and busses. The results of the current tests are important to national and international standardization activities – with the aim to guarantee interoperability of inductive charging systems of different suppliers and vehicle manufacturers.

Seven Auto Makers Agree to single-port DC fast charging standard

Recognizing the importance of a single international approach for DC fast charging, Audi, BMW, Daimler, Ford, General Motors, Porsche and Volkswagen have agreed on the combined charging system as an international standardized approach to charge electric vehicles (EV) in Europe and the United States.

The system is a combined charging approach integrating all charging scenarios into one vehicle inlet/charging connector and uses identical ways for the vehicle to communicate with the charging station. This allows electric vehicles from Audi, BMW, Daimler, Ford, General Motors, Porsche and Volkswagen can share the same fast charging stations.

The seven auto manufacturers believe the development of a common charging approach is good for customers, the industry and charging infrastructure providers. Standardization will reduce build complexity for manufacturers, accelerate the installation of common systems internationally and most importantly, improve the ownership experience for EV drivers.

The endorsement of the combined charging system was based on reviews and analysis of existing charging strategies, the ergonomics of the connector and the preferences of customers in both the United States and Europe. The harmonized approach – across both continents and all manufacturers - will provide a framework for future infrastructure planning as well as a communication protocol to assist in the integration of electric vehicles into the smart grids.

The seven auto manufacturers also agreed to use HomePlug Green Phy as the communication protocol. This approach will also facilitate integration of the electric vehicle into future smart grid applications.

Automakers point to the success of Level 1 and Level 2 (for 220V charging in the U.S.) as an example of how standardization will increase the adoption of electric vehicles and increase customer satisfaction. The harmonized electric vehicle charging solution is backward compatible with the J1772 connector standard in the U.S. Backward compatibility also has been achieved in Europe where the system is based on the IEC 62196 Type 2. The approval of the J1772 standard has given electric vehicle owners the comfort of knowing they can charge at all Level 2 charging stations. Prior to standardization an EV owner had no way of knowing if the charge port they were pulling up to was compatible with their vehicle.

AMG Lightweight Performance: SLS AMG E-CELL gets carbon-fibre spine

The SLS AMG E-CELL body shell being shown by Mercedes-Benz AMG at the IAA 2011 is one trailblazing outcome of its ambitious "AMG Lightweight Performance" design strategy. Its key element is a transmission tunnel made out of lightweight carbon-fibre composite material (CFRP), which is structurally integrated into the aluminium body shell and firmly bonded with it. The high-strength and stiff CFRP component helps to reduce weight, while also serving as a monocoque housing for the battery modules.

The carbon-fibre battery monocoque in the SLS AMG E-CELL forms an integral part of the body shell and acts as the vehicle's "spine". The advantages of carbon composite materials were specifically exploited by the AMG engineers in its design. These include their high strength, which makes it possible to create extremely rigid structures in terms of torsion and bending, excellent crash performance and low weight. CFRP components are up to 50 percent lighter than comparable steel ones, yet retain the same level of stability.

Compared with aluminium, the weight saving is still around 30 percent, while the material is considerably thinner. The advantages in terms of weight achieved through the carbon-fibre battery monocoque are reflected in the agility of the SLS AMG E-CELL and, in conjunction with the highly innovative wheel-selective four-wheel drive system, ensure true driving enjoyment.

The carbon-fibre battery monocoque is, in addition, conceived as a "zero intrusion cell" in order to meet the very highest expectations in terms of crash safety. It protects the battery modules inside the vehicle from deformation or damage in the event of a crash.

Tobias Moers, Member of the Board of Management of Mercedes-AMG GmbH, responsible for overall vehicle development: "AMG Lightweight Performance is the term we use at AMG to encompass all the different technologies involved in lightweight construction. The use of carbon makes vehicles not only lighter, but even more efficient and agile – in motorsports and on the streets. This is especially important for sports cars."

The basis for CFRP construction is provided by fine carbon fibres, ten times thinner than a human hair. A length of this innovative fibre reaching from here to the moon would weigh a mere 25 grams. Between 1000 and 24,000 of these fibres are used to form individual strands. Machines then weave and sew them into fibre mats several layers thick, which can be moulded into three-dimensional shapes. When injected with liquid synthetic resin, this hardens to give the desired structure its final shape and stability.

Through their experience with the SLR, the vehicles in the AMG Black Series and in motorsport, Mercedes-Benz and AMG have accumulated more than 10 years of expertise in working with carbon-fibre materials. AMG currently makes the propshaft for the SLS AMG, for example, in carbon-fibre. On the SLS Roadster, the supporting structure for the draught-stop is made as standard as a carbon sandwich structure. This component, with extremely short cycle times in an industrially oriented manufacturing process, already demonstrates what will be possible in the future.

CFRP components also play an important role in Mercedes-Benz and AMG's lightweight design strategy for the future. In conformity with the motto "the right material, in the right place, the proportion of high-strength steels, aluminium and fibre-reinforced plastics is set to increase significantly in the future. The body shell weight of all Mercedes-Benz vehicles should fall by ten percent compared with their predecessors.

Just how seriously Mercedes-Benz and its high-performance arm AMG are treating the issue of lightweight design as an important factor along the road to sustainable mobility, is demonstrated by the full-aluminium body shell of the SLS AMG. With it, the super sports model shows the way for future model ranges.

Mercedes unveil B-Class E-Cell Plus extended-range EV concept [video]

Mercedes-Benz will be presenting its first electric vehicle with Range Extender at the 2011 Frankfurt International Motor Show in the guise of the Concept B-Class E-CELL PLUS. The combination of electric drive and petrol engine ensures excellent suitability for both everyday use and long journeys. The energy accumulator takes the form of a lithium-ion battery from Deutsche Accumotive, which enables local emission-free driving up to a range of 100 kilometres. Thanks to the additional three-cylinder petrol engine, the Concept B-Class E-CELL PLUS has a total range of up to 600 km. The concept vehicle presented at the 2011 Frankfurt International Motor Show provides a foretaste of the series which is to go into production in 2014. The Concept B-Class E-CELL PLUS adds an all-purpose battery-powered vehicle with Range Extender to Mercedes-Benz's range of electric vehicles.

A new addition to Mercedes-Benz's portfolio of electric cars is the near-series Concept B-Class E-CELL PLUS – a compact model that meets all the needs of daily motoring with a total range of up to 600 kilometres. As such, this electric vehicle is also ideally suited to long journeys and offers its driver unrestricted mobility. This is made possible by the combination of a powerful electric drive generating a peak power output of 100 kW and a continuous output of 70 KW with a 50 kW petrol engine. The latter performs a dual role: at low vehicle speeds it charges the battery via a generator. At higher speeds – on prolonged motorway stretches, for example – it additionally serves as a driving engine, acting on the front wheels together with the electric motor via a newly developed automatic transmission.

In all-electric, local emission-free mode the Concept B-Class E-CELL PLUS has a range of up to 100 kilometres. This covers over 80 percent of daily driving needs. The total range of up to 600 kilometres allows the vehicle to be used for long journeys, too. This means that the electric vehicle with Range Extender is fully suitable for everyday use and can be relied upon to reach its destination, even with a fully discharged battery. In combined driving mode the vehicle emits 32 grams of CO2 per kilometre.

"The Concept B-Class E-CELL PLUS shows that our new range of compact cars is all set for the future. The variant involving a battery-electric vehicle with Range Extender further broadens the range of alternative drive concepts from Mercedes-Benz," notes Prof Dr Thomas Weber, Member of the Board of Management at Daimler AG, responsible for Group Research and Mercedes-Benz Cars Development. "This innovative and highly flexible concept meets our customers' wish for emission-free driving coupled with a large range."

The vehicle concept – the best of two worlds

The Concept B-Class E-CELL PLUS is an electric vehicle meeting all daily motoring needs which combines the best of two worlds: all-electric driving and driving with a tried and tested high-tech combustion engine. This combination allows long journeys which to date have been the reserve of vehicles powered by a combustion engine alone or electric cars fitted with a fuel cell. The two drive units are extremely compact and are accommodated in the engine compartment at the front together with the transmission and the generator. The powerful lithium-ion battery and the fuel tank are located in a false floor at the rear – the so-called "Energy Space" – which has been developed specially for alternative drives. For other drive variants it is also possible to install gas or hydrogen tanks here, for example.

Intelligent control of the drive system for unrestricted mobility

The intelligent electronic control system of the Concept B-Class E-CELL PLUS ensures perfect handling in every driving situation. Activation and deactivation of the combustion engine take place fully automatically and go unnoticed by the driver. Electric motor and combustion engine work so intelligently together that the drive unit is able to select the most fuel-efficient mode in every driving situation in a fraction of a second – from stop and go in the city to speedy driving on the open road. With the Concept B-Class E-CELL PLUS there are basically two operating modes, depending on the battery charge status:

When the battery possesses sufficient energy, the vehicle runs locally emission-free on electric power alone. The energy accumulator can be recharged by means of a conventional domestic power socket. Rapid charging is also possible with this vehicle. This enables a charging time in the order of one hour.

When the battery charge status drops below a certain limit, the combustion engine is activated ("Range Extender mode"). The large range which is available in "Range Extender mode" ensures that the vehicle will always reach its destination, even if the battery is flat. Acceleration from 0 to 100 km/h in approx. 11 seconds and the top speed of 150 km/h are both attainable in either operating mode. In order to ensure the most efficient possible motoring, two variants are possible, depending on the vehicle's speed:

Below a speed of around 60 km/h, the combustion engine and generator attend to on-board power generation ("serial mode"). In this case, the combustion engine is run in the most fuel-efficient mode.

At speeds of over 60 km/h the combustion engine acts as a driving engine together with the electric motor ("parallel mode"), transmitting the generated power to the front axle. Any excess power generated by the combustion engine is used to charge the battery and to run the ancillary units.

Highly efficient lithium-ion battery with long service life

The energy accumulator is accommodated in a false floor system at the rear of the vehicle – the so-called "Energy Space" – which has been developed by Mercedes-Benz specifically for alternative drives. The energy accumulator employed here is a particularly powerful state-of-the-art lithium-ion battery designed specifically for automotive applications. It is produced by Deutsche Accumotive GmbH & Co. KG, a joint venture of Daimler and Evonik.

The battery can be charged using any standard domestic power outlet or at a public charging station, by means of the charge socket integrated in the rear bumper and the 3.3 kW on-board charger.

When the car goes into production, convenient remote checking and remote configuration of the vehicle will be possible by means of the so-called Vehicle Homepage. The driver will be able to access his vehicle via the internet, using his PC or smartphone. In this way, it will be possible to check the current charge status of the lithium-ion battery or to verify the vehicle's current range on a map. A further feature is smart charging. This involves the customer selecting a desired time for the beginning of his journey. The system then ensures that the battery is fully charged and, if desired, that the vehicle is air‑conditioned at this point in time. The facilities offered by the Vehicle Homepage are rounded off by further convenience functions, such as a route planner designed specifically for electric vehicles.

Comfort and safety to the highest standard

In terms of safety and comfort, the Concept B-Class E-CELL PLUS meets Mercedes-Benz's high standards in every respect. The vehicle combines compact exterior dimensions with a spacious and variable interior and luggage compartment. Five full-size seats make it an all-round electric car for the family, leisure and general motoring. The new electromechanical steering and enhanced driving dynamics provide for refined sportiness in the field
of electric mobility. A striking feature of the Concept B-Class is the copper-coloured linear graphic design which accentuates the vehicle and lends it a dynamic appearance. High-quality black nappa leather and copper-coloured double lap seams have been used in the interior.
The concept vehicle is a match for its siblings when it comes to active and passive safety features, too. Like all models of the new compact car generation, the Concept B-Class E-CELL PLUS also comes with COLLISION PREVENTION ASSIST, a new assistance system which will help to avoid rear-end collisions in future. In keeping with the ongoing democratisation of safety, the B-Class E‑CELL PLUS will also feature a number of additional assistance systems adopted from the larger model series.

These include:

Adaptive Highbeam Assist
Blind Spot Assist and Lane Keeping Assist
Attention Assist (standard)
Speed Limit Assist (speed limit sign recognition)
Active Parking Assist
Brake HOLD function (standard with 7G-DCT)
Hill Hold function
LINGUATRONIC
Reversing camera
PRE-SAFE® (featuring for the first time in this class of vehicle)

As such, the Concept B-Class E-CELL PLUS sets new standards in the areas of compact electric vehicles with regard to comfort, safety and agility.

Bosch and Daimler Sign EV Motor JV, Production starts 2012

Robert Bosch GmbH and Daimler AG have concluded negotiations and signed an agreement for the establishment of a 50:50 joint venture. The aim of the joint venture is to develop and manufacture electric motors. The contract is subject to approval by the responsible antitrust authorities. The new company will operate under the name EM-motive GmbH. It will be headquartered in Hildesheim, where a manufacturing site will also be located. The joint venture’s development site will be located in the Stuttgart area, where both parent companies are headquartered. Some 100 associates will begin working for the joint venture in the fourth quarter of 2011. EM-motive GmbH will be headed by two executives of equal status from each of the parent companies.

The cooperation between Bosch and Daimler in the area of e-mobility aims to pool expertise and utilize synergies to speed up the development of high-quality traction machines for electric vehicles with batteries, fuel cells or range extenders.

Wolf-Henning Scheider, member of the Bosch board of management responsible for the Chassis Systems Control, Electrical Drives, and Starter Motors divisions, said: “This joint venture is an investment into the future of Europe’s automotive industry. It will enable us to expand our portfolio of electric motors for all our customers in an ideal manner. I strongly believe that our common products will shape the future e-mobility market, and that we will quickly reach a high level of market penetration.”

From 2012, the joint venture’s traction machines will be featured in vehicles of the Mercedes-Benz and smart brands. The new generation of the smart fortwo electric drive, which is set to be launched in the spring of 2012, will be the first vehicle to be equipped with EM-motive technologies.

A clear strength of the joint venture's electric motors is their modularity. It will enable Bosch to offer its customers a broad range of motors that are suited to vehicles of different classes, including a range of purely electric vehicles. The motors can be adapted to different performance requirements, and can be fitted in many types of vehicle, including cars, vans, and delivery vehicles.

A special characteristic of the joint venture is that Bosch will be able to sell EM-motive products to third party customers. As a result, Bosch will remain a trusted partner to carmakers in the future. The joint venture will create economies of scale, which will help keep costs down. This will in turn be beneficial to all customers. By 2020, the joint venture expects to produce more than one million electric motors.

Both parent companies will contribute their engineering expertise to develop and manufacture electric traction motors. Carmaker Daimler brings 20 years of experience in the area of e-mobility into the joint venture, particularly in the areas of fuel cell and battery technology. The company has comprehensive expertise with regard to the development and manufacture of electric vehicles.

Brabus will present high-performance 4WD Full Electric [video]

Mercedes tuner Brabus is bringing a few cars to the Frankfurt motor show, but instead of fire-breathing, gas-drinking supercars, they're electric.

The company that brought us the 738-hp Brabus SL600 and the 788-hp Brabus S600 R is turning its considerable tuning powers to low-emission luxury cars--for now.

Brabus Zero Emission, the alternative-drive side of the Brabus business, will have two prototypes on display at the Frankfurt show. The first is a version of the European Mercedes E220 diesel called Technology Project Hybrid. It uses two electric motors at the wheel hubs to keep fuel economy up.

The second is an all-electric version of the sedan with four wheel-hub motors and 2,360 lb-ft of torque at the wheels.

The Technology Project Hybrid from Brabus has a direct-injection, 2.2-liter common-rail diesel engine with two supplemental hub motors from English manufacturer Protean Electric. Those motors produce 67 hp each in normal mode and 107 hp each when the sport button is pressed. Torque from the two hubs is rated at an astonishing 1,180 lb-ft, according to Brabus.

During electric cruising, the Mercedes is powered by an 18.6-kilowatt-hour lithium-ion battery pack. The company says that in eco mode the car can travel 75 miles with zero emissions. In sport mode, the vehicle can still go 50 miles. When both the engine and the electric motors are used, the car can go from 0 to 60 mph in just more than seven seconds. Drivers can also opt to cruise in standard diesel mode.

The system can recharge when coasting or braking, up to 140 kilowatts. For home charging, Brabus partnered with German energy provider RWE to create a 380-volt unit that can fill up the battery in 30 minutes, the company says. On a 220-volt outlet, it takes about 5.6 hours.

The extra weight of the car dictated an upgrade to the suspension. Brabus added a height-adjustable sport setup with variable dampers developed with Bilstein.

For the finishing touch, Brabus adds unique body panels, LED daytime running lights, sill plates and a new instrument cluster the displays all of the hybrid-related information.

The second car from the company will be a 320 kW (429-hp), 3,200 Nm all-electric vehicle based on the E-class sedan. It will come with a range of 217 miles, according to the company. The Brabus High Performance 4WD Full Electric will have four motors at the wheels making 80 kW and 800 Nm of torque each.

The fully electric E-class will be a heavyweight at 2,200 kg but will benefit from electric motors that provide 100 percent of torque at zero rpm. The sprint to 60 mph will take less than seven seconds, according to the company. But because of the wheel-hub motors' maximum speed of 2,000 rpm, top speed will be 137 mph.

There are benefits to putting motors at each of the wheels. Besides eliminating significant drivetrain loss, the all-wheel-drive system can disperse torque even more efficiently with the electric motors during slippery conditions and maximize brake regeneration.

Charging will take 1.5 hours with the 380-volt charger and about five hours with the 220-volt unit.

The cars are prototypes, so no prices have been announced yet. The company does say, however, that both could be put in to low-volume production in the future.

Smart Forvision Concept (by Mercedes and BASF) [video]

A promotional video has now been released of the Daimler and BASF developed Smart Forvision EV concept vehicle that we reported earlier this week.

Daimler and BASF Jointly develop Smart Forvision EV concept

Daimler and BASF have developed a new concept vehicle that combines both companies' ideas for holistic electric mobility. The resulting vehicle is the smart forvision, which has been developed with a special emphasis on energy efficiency, temperature management and lightweight design. The smart forvision will have its world premiere at the 64th International Motor Show in Frankfurt.

Both Daimler and BASF are engaged in wide-ranging research and development work aimed at getting electric cars on the road and ensuring that electric mobility becomes part of everyday life as soon as possible. Daimler is embracing the age of electric mobility: it is the first car manufacturer to have released four electric production models, and its smart fortwo electric drive is a pioneer among battery-driven vehicles. BASF, the world's largest supplier of chemical products to the automotive industry, develops sustainable, environmentally friendly solutions for the energy-efficient mobility of tomorrow. The two companies have now combined their technological competencies for the first time, developing a forward-looking vehicle concept that offers decisive solutions to the challenges of the future. The new vehicle brings design, lifestyle and technology together to form a new functional whole.

"In this joint project with Daimler we have successfully developed a holistic approach to urban mobility of the future. This is something we are very proud of. Our research activities make an important contribution to ensuring that electric cars are affordable, environmentally friendly and sustainable," says Dr. Andreas Kreimeyer, member of the Board of Executive Directors and Research Executive Director of BASF SE.

"The smart forvision is an impressive example of what can be achieved when two leading companies from two very different sectors sit down together. It was exciting to see how our developers and designers worked with the researchers at BASF and came up with a joint vehicle concept that provides a meaningful insight into the future of electric mobility," says Dr. Thomas Weber, Daimler AG board member responsible for Group Research and Development at Mercedes-Benz Cars.

Because it has always set itself apart from other vehicle concepts, the smart was predestined for this joint project. As a result, the smart forvision is the perfect vehicle for showcasing new technologies. The researchers and developers have succeeded in combining no less than five automotive world premieres in the new concept vehicle. Transparent organic solar cells, transparent organic light-emitting diodes, all-plastic wheels, new lightweight body components and infrared-reflective films and coatings all help to reduce the vehicle's energy consumption and thus increase its range and practicality.

Energy efficiency

State-of-the-art materials and technologies allow new concepts to be implemented in the electric car that not only save energy, but even generate it. The resulting increase in range contributes to further improving the performance and economy of electric vehicles. The smart forvision features energy-efficient solutions such as power-generating solar cells based on organic-chemical dyes on the roof. Combined together with energy-saving organic light-emitting diodes (OLEDs), the vehicle's roof, which is covered in solar cells, is not just environmentally friendly, but a real design highlight as well.

One challenge in ensuring the continuing development of electric mobility is sustainably producing and using the power required to drive the cars. Electric mobility is at its most effective in preventing climate change and protecting the environment when the energy required for it is generated highly efficiently and with minimal CO2 emissions. For this reason BASF is also working on solutions for producing electricity from renewable energies such as wind and solar power.

Multifunctional lightweight design

The lighter an electric vehicle is, the less drive energy it requires, and the greater its range will be. Making vehicles lighter will therefore be one of the key challenges for electric mobility in the future, and BASF can make an important contribution here. Lightweight design means replacing heavy, metal components with composite plastic materials that offer the same functionality and stability. Weight can be reduced particularly successfully by substituting load-bearing components, for example the chassis, with fiber-reinforced plastics. Moreover, the smart forvision features the first ever all-plastic wheel suitable for series production, made from the new high-performance material Ultramid® Structure developed by BASF. This material, which is just as stable as metal, can reduce weight by up to 30 percent.

Comprehensive temperature management

The heating and air conditioning systems in vehicles are major consumers of energy. The amount of energy needed to heat up or cool down the vehicle's interior can be reduced with the help of a comprehensive temperature management system that uses innovative materials such as polymer films in the windows to reflect thermal radiation, and high-performance insulating materials.
The smart forvision brings together these forward-looking technologies from the chemical industry with a unique mobility concept and distinctive design. Together, the automotive and chemical industries are making a significant contribution to the affordability, environmental friendliness and safety of electric vehicles. In the smart forvision, Daimler and BASF have laid the perfect foundations for efficient, sustainable, uncompromising electric mobility.

Toyota could return to the Le Mans 24 Hours as early as 2012

Toyota has been testing an all-new LMP1 car since last year, and could return to the Le Mans 24 Hours as early as 2012, according to this week's AUTOSPORT magazine.

The Japanese manufacturer commissioned the machine, which is known to incorporate hybrid technology and comply with the 2011 prototype technical regulations, from racing car constructor Dome.

When asked about the possibility of Toyota returning to top-line prototype racing, Vincent Beaumesnil, sporting manager of Le Mans organiser the Automobile Club de l'Ouest, said: "We are in contact with many manufacturers who are interested in LMP1, not just Toyota."

Toyota last competed at Le Mans as a full manufacturer in 1999, but supplied engines to the Rebellion LMP1 squad on a customer basis this year.

Mercedes plans electric S-class

A full electric version of the next Mercedes S-class is not being ruled out, according to the firm’s technical boss, Thomas Weber.

“At the moment, we are looking at customer demand,” he admitted.

The next-generation car will have hybrid and plug-in hybrid versions, though. At the heart of the standard engine range will be Mercedes’ new V6 and V8 MoVe petrol powerplants. Diesel options are likely to include the 201bhp, 369lb ft 2.2-litre, four-cylinder motor from the current S250 CDI, the smallest engine to ever be offered in the S-class.

The new luxury saloon will also carry over no cabin architecture from existing models. But hints of its design can be seen in the F800 Style concept revealed at the Geneva motor show in March.

It will also showcase new interior technologies such as more reliance on head-up displays and a move into driver-oriented virtual displays.

BYD-Daimler’s First EV Design Completed, Prototyping Started

The 50:50 Joint Venture between BYD and Daimler Mercedes-Benz (called the Shenzhen BYD Daimler New Technology Company Limited), announced at its first board meeting since receiving its business license from the Market Supervision Administration of Shenzhen (MSAS) that Mr. Ulrich Walker CEO of Daimler Northeast Asia Investment Co. Ltd, would be the Chairman of the Board of BYD-Daimler and that Mr. Yubo Lian Senior Vice President of BYD Co., Ltd and Chief Engineer of BYD’s auto business would be President and CEO.

The Joint Venture has made significant progress since cooperation began over a year ago – the design of the first BYD-Daimler electric vehicle (EV) model has been finalized and prototyping has been kicked off – a major milestone. Both parties will work on EV production preparations and team members from design, engineering, procurement, and quality management have all relocated to the BYD Shenzhen Headquarters.

From the outset of the collaboration, BYD and Daimler put special emphasis on high quality standards for design of the vehicle. The whole process of new vehicle design has been closely supervised by Mercedes-Benz Quality Management experts. This process has included creating a new international supply chain and the selection of the right combination of mold-makers and high-quality component suppliers. Cooperation with the World‘s leading suppliers plays an important role in safeguarding the new vehicle’s superior quality. The electric vehicle co-developed by the joint venture will capitalize on Daimler’s know-how in highly-reliable and safe electric vehicle architectures as well as combining BYD’s leading-edge, environmentally-friendly, Iron-Phosphate battery technology and electric drive systems. The vehicle will be marketed under the new brand jointly created and owned by Daimler and BYD.

Daimler, Bosch Join in Electric Car Venture

Daimler will team up with industrial giant Bosch in a joint venture to produce electric motors to be used in Mercedes and Smart cars next year, both companies said on April 12.

The two firms have signed a letter of intent and joint production should start in 2012 at sites in Hildesheim in central Germany and Stuttgart in the south-west.

The 50-50 joint venture, which should be in place by the end of June, aims "to accelerate development advances in electric motors," a statement said.

Home to many of the world's top car firms, Germany has been slow off the starting grid when it comes to developing electric vehicles, with Japan and the United States powering ahead.

The world's leading luxury car maker, BMW, said last year it would invest 400 million euros (US$575 million) by 2013 to produce an electric car as German manufacturers scramble to catch up with global rivals.

Chancellor Angela Merkel's government has offered sweeteners to auto firms to hit the government's target of having one million electric cars on the road by 2020.

SK Innovation to Supply Batteries to Mercedes SLS AMG E-Cell supercar

SK Innovation Co., parent of South Korea’s biggest oil refiner, said it will supply lithium-ion batteries for Daimler AG’s Mercedes-Benz SLS AMG E-Cell supercar.

Shipment schedules and volumes haven’t been fixed, according to a regulatory filing today.

SK Innovation is competing with chemical maker LG Chem Ltd. for a share of the car-battery market and has won orders from Hyundai Motor Co., Kia Motors Corp. and Daimler’s Japanese unit, Mitsubishi Fuso Truck & Bus Corp.

The South Korean company, previously known as SK Energy Co., is focusing on overseas energy exploration and new businesses such as electric-car batteries after completing the spin-off of its petroleum and petrochemical operations on Jan. 1.

Daimler moving fast on hybrids

Daimler will offer hybrid versions of its Mercedes-Benz C-, E- and S-class vehicles in the United States and Europe within three years to meet tightening global fuel economy standards.

Herbert Kohler, head of Daimler's E-Drive and Future Mobility unit, said Daimler is moving quickly on hybrid technologies. "We have a leading position in the premium segment concerning alternative propulsion systems, and we will defend it," he said.

A Daimler source said the C- and E-class full hybrids will be launched in Europe before 2013 and the S-class plug-in hybrid will be launched in 2014.

A second source said U.S. versions will follow about six months later.

Mercedes does not currently offer a plug-in version of its vehicles in the United States. The current S400 is offered as a mild hybrid, and the M class is a full hybrid.

A mild hybrid uses an electric motor and acts as a start/stop system, but the electric motor does not drive the vehicle by itself. A full hybrid can be driven short distances using the electric motor.

Kohler also said Daimler will continue to invest heavily in r&d this year, spending half of its $5.6 billion budget on alternative powertrain technology.

Mercedes-Benz SLS AMG E-Cell @ Detroit Auto Show

Mercedes-AMG is rising to the challenges of the automotive future: the SLS AMG E-CELL showcases state-of-the-art development of an exciting super sports car with a zero-emission high-tech drivetrain. Boasting a power output of 526 hp and 649 lb-ft of torque, this prototype vehicle from AMG offers exceptional performance. The gullwing with electric drive is part of the company strategy entitled "AMG Performance 2015" which aims to continually reduce fuel consumption and emissions.

With the SLS AMG E-CELL, Mercedes-AMG is providing a glimpse of its latest development project - a powerful and locally emission-free super sports car. Finished in fluorescent "AMG lumilectric magno" paint, the gullwing offers a glimpse at a possiblesmall series production vehicle and at the same time reflects the innovative strength and development expertise of the AMG performance brand.

"We take social responsibility very seriously and with the SLS AMG E-CELL we are demonstrating a further milestone in our "AMG Performance 2015" strategy. It is our goal to continually reduce the fuel consumption and emissions of new models in the coming years, while at the same time enhancing the core brand value of performance", explains Ola Källenius, chairman of the board (from 1 July 2010) of Mercedes-AMG GmbH. With the SLS AMG E-CELL, the performance brand of Mercedes-Benz is launching a totally innovative drivetrain for super sports cars, reaching new territory in this market segment.

The ground-breaking drive system boasts some impressive highlights: powerful traction is provided by four synchronous electric motors with a combined peak output of 526 hp and a maximum torque of 649 lb-ft. The four compact electric motors each achieve a maximum rpm of 12,000 rpm and are positioned near the wheels. As a result, compared with wheel-hub motors the unsprung masses are substantially reduced. One transmission per axle transmits the power.

Acceleration from zero to 60 mph in 4 seconds

When it comes to dynamics, the electrically-powered SLS AMG makes a statement: the gull-wing model accelerates from zero to 60 mph in 4 seconds - which almost puts it on the same high level as the SLS AMG with 6.3-liter V8 engine developing 563 hp (0-60 mph in 3.7 seconds).

Further driving excitement is provided by the agile accelerator response and straight-line performance: unlike the combustion engine, torque build-up with an electric motor is instantaneous - maximum torque is available virtually from a standstill. The spontaneous torque build-up and effortless power delivery - which does not diminish by any interruption of tractive power - are combined with engine running characteristics which are totally free of vibration. Four motors, four wheels: the intelligent and permanent all-wheel drive of the electric SLS guarantees driving dynamics at the highest level, while at the same time providing the best possible active safety. All four driven wheels achieve optimal traction, independent of weather conditions.

This very special gullwing is therefore able to "electrify" the driver with a completely unique, effortlessly superior and emotional super sports car driving experience, even at this early, prototype stage of development. In brief: the SLS AMG E-CELL is true to the AMG brand.

High-voltage lithium-ion battery provides 400 v and 40 Ah

The SLS AMG E-CELL drive incorporates a liquid-cooled high-voltage lithium-ion battery featuring a modular design with an energy content of 48 kWh and a capacity of 40 Ah. The maximum electric load potential of the battery, which consists of 324 lithium-ion polymer cells, is 480 kW, which is an absolute best figure in the automotive sector. Another technical feature of this considerable performance is the intelligent parallel circuit of the individual battery modules - this also helps to maximize the safety, reliability and service life of the battery. The 400-volt battery is charged by means of targeted recuperation during braking while the car is being driven.

High-performance electronic control as well as effective cooling of all components

A high-performance electronic control system converts the direct current from the high-voltage battery into three-phase alternating current which is required for the synchronous motors and regulates the energy flow for all operating conditions. Two low-temperature cooling circuits ensure that the four electric motors and the power electronics are maintained at an even operating temperature. A separate low-temperature circuit is responsible for cooling the high-voltage lithium-ion battery. In low external temperatures, the battery is quickly brought up to operating temperature with the aid of an electric heating element. This helps to preserve the overall service life of the battery. In extremely high external temperatures, the cooling circuit for the battery can be additionally boosted with the aid of the air conditioning system.

Optimum weight distribution and low center of gravity

The purely electric drive system was taken into consideration early in the development of the SLS AMG. Thus, the SLS easily integrates the high-performance, zero-emission technology into its structure: for example, the four electric motors and the two transmissions can be positioned as close to the four wheels as possible and very low down in the vehicle. The same applies to the modular high-current battery, whose modules are located in front of the firewall, in the center tunnel and behind the seats. Advantages of this solution include the vehicle's low center of gravity and balanced weight distribution - ideal conditions for optimum handling, which the electrically-powered SLS AMG shares with its gasoline-powered sister model.

The installation of the drive components required no changes whatsoever to the car's weight-optimized aluminum spaceframe, and there were just as few constraints when it came to maintaining the excellent level of passive safety and high degree of long-distance comfort that are hallmarks of Mercedes-Benz cars.

New front axle design with pushrod damper struts

The additional front-wheel drive called for a newly designed front axle: unlike the series production vehicle with AMG V8 engine, which has a double wishbone axle, the SLS AMG E-CELL features an independent multilink suspension with pushrod damper struts. This is because the vertically-arranged damper struts in the series SLS had to make way for the additional drive shafts. As is usual in a wide variety of racing vehicles, horizontal damper struts are now used, which are operated via separate push rods and transfer levers.

Thanks to this sophisticated front-axle design, which has already been tried and tested in the racing world, the agility and driving dynamics of the electrically-powered SLS AMG attain the same high levels as the V8 variant. Another distinguishing feature is the speed-sensitive power steering with rack-and-pinion steering gear: the power assistance is implemented electrohydraulically rather than just hydraulically.

AMG ceramic composite brakes for perfect deceleration

The prototype vehicle is slowed with the aid of AMG ceramic composite brakes, available as an optional extra for the series production model, which boast extremely short stopping distances, a precise actuation point and outstanding fade resistance, even in extreme operating conditions. The over-sized discs - measuring 15.8 x 1.5 in. at the front and 14.2 x 1.3 in. at the rear - are made of carbon fiber-strengthened ceramic, feature an integral design all around and are connected to an aluminum bowl in a radically floating arrangement.

The ceramic brake discs are 40 percent lighter in weight than the conventional, grey cast iron brake discs. The reduction in unsprung masses not only improves handling dynamics and agility, but also ride comfort and tire grip. The lower rotating masses at the front axle also ensure a more direct steering response - which is particularly noticeable when taking highway bends at high speed. The ABS and ESP® systems have been adapted to match the special handling of the permanent all-wheel drive.

Full-LED headlamps and automatically extending front splitter

The clean, exciting design of the prototype vehicle boasts a number of minor yet extremely effective modifications. At the front, the dynamically shaped full-LED headlamps with integrated daytime driving lights immediately catch the eye: they help to optimize the vehicle's energy efficiency, since they require less power compared with regular bi-xenon headlights. The wider radiator grille also has a new look, and now comes with transverse slats instead of a diamond-pattern. The air outlet openings on the hood and the vehicle sides have also been modified for enhanced aerodynamics. All trim and detachable parts, which are finished in chrome or silver shadow on the standard SLS AMG, are now finished in matte black.

The front apron has not only been brought further forward, but also helps optimize airflow to the underbody. This improves wind resistance while reducing downforce. An extendable front splitter enhances this effect: in parallel with the automatic rear spoiler, it extends downwards by three inches at speeds above 75 mph and helps to further accelerate the air which travels beneath the car. When it reaches the area of the rear axle, the air enters the rear diffuser which, due to the lack of an exhaust system, features a steeper angle, thus increasing downforce at the rear axle and in turn further enhancing the aerodynamic balance. The vehicle's AMG 10-spoke light-alloy wheels feature a new, smooth-surfaced design and are fitted with 265/35 R 19 (front) and 295/30 R 20 (rear) tires.

Interior with new display instruments for electric drive

The transformation from gasoline to electric super sports car also called for some specific changes to the interior. As a result, the AMG instrument cluster and center console in particular both feature a new design. The new AMG instrument cluster provides information on speed, charge status of the battery and the estimated range. The newly designed center console now houses a 10-inch touchscreen, which driver and passenger can use to conveniently operate all of the audio, climate and navigation functions, and also obtain information on the flow of power from the four electric motors.

The AMG Drive Unit, which is angled towards the driver, houses buttons for starting the motor, and the ESP® functions, the AMG memory function and the extendable front splitter and rear spoiler. Using three new buttons, the driver can switch simply between P, R and D. The park setting is also enabled automatically by switching the electric motors off.

The interior appointments are dominated by high-quality premium leather in a black/white color combination - it has been used not only on the sports seats, the performance leather/alcantara steering wheel and the door linings, but also on the broad center console which runs towards the back of the vehicle between the seats.

Mercedes is developing Mega City car to match rival BMW

According to a recent report, Mercedes is developing a new car to battle the BMW Megacity.

Tentatively dubbed the Megacity Mobility (MCM), the vehicle will feature aerodynamic styling which is being created by the company's Japanese design studio. Furthermore, initial reports suggest the car will use an electric powertrain and ride on the next-generation Smart ForTwo platform.

As we have previously reported, the 2013 BMW Megacity will feature a carbon fiber reinforced plastic (CFRP) body and a 150 hp (112 kW / 152 PS) electric motor. It will be powered by a 35 kWh lithium-ion battery and have a range of approximately 100 miles (161 km).

Mercedes Electric Vito Taxi wins Future Car Challenge

A seven-seat electric taxi was awarded Most Economic & Environment Friendly Multi-Purpose Electric Vehicle at the Royal Automobile Club's (RAC) Future Car Challenge.

The Mercedes Electric Vito (eVito) Taxi, which was a collaboration between Mercedes Benz, Zytek Automotive, and Valence, is powered by Valence batteries.

The challenge was to produce a concept of a pollution-free fleet vehicle that could be used as taxis during the Olympic games.

The eVito beat out 59 other vehicles by finishing the 57-mile run with about 30 percent of its battery capacity remaining.

"We're very gratified that the eVito outperformed its competition in the challenge, which we hope will further raise awareness of the bright future Valence is enabling for electric fleets," said Robert L. Kanode, president and chief executive officer of Valence Technology.

Daimler CEO Calls on Governments to Offset Electric-Car Costs

Daimler AG Chief Executive Officer Dieter Zetsche said governments should offer consumers financial incentives to buy electric vehicles to help offset the extra cost for manufacturers to build the cars.

“Even in the best case, the cost of electric autos might run several thousand euros more than conventional vehicles for the foreseeable future,” Zetsche said today in a speech in Stuttgart. “In other words, we need appropriate sales incentives.”

Daimler, the maker of Mercedes-Benz cars and trucks, is developing battery-powered versions of the gull-wing SLS sports car and two-seater Smart city car, to meet regulatory demands to reduce carbon-dioxide emissions and compete with rival Bayerische Motoren Werke AG. Daimler, which targets producing more than 10,000 electric cars by 2012, is building a factory in eastern Germany to produce lithium-ion power packs.

Manufacturers will struggle to make a profit from electric vehicles, which will likely account for less than 10 percent of the cars on the road in 10 years, Zetsche said, adding that the growth of electric car sales will occur “in many small steps.”

“We won’t earn high returns from electric vehicles for years to come,” said Zetsche, who heads the world’s second- largest maker of luxury cars. “That is the optimistic way of putting it.”

Government incentives for electric cars should be linked to technological advances such as battery performance, Zetsche said at a company event on sustainability, which also included a discussion of ethics.

Zetsche, who plans to add an executive to oversee ethical and legal issues to Daimler’s board, halted the company’s business in Iran this year because of the government’s political positions.

“Not every deal that’s legal is legitimate,” said Zetsche, noting that neither Zimbabwe’s President Robert Mugabe nor Sudan’s President Umar Al-Bashir were Daimler customers. “No deal in the world is worth risking our good reputation.”

Two Daimler AG units pleaded guilty to violations of the U.S. Foreign Corrupt Practices Act earlier this year. The pleas from the Russian and German units were part of an agreement with prosecutors to resolve allegations the German carmaker paid bribes to foreign officials.
