Daimler invests in ChargePoint

Daimler AG is investing heavily in electric mobility. As part of this, investments are being made far beyond just vehicle development. As part of the electric mobility offensive from Mercedes-Benz Cars, in the coming years the company is investing around €10 billion in the expansion of its product portfolio comprised under the EQ brand. Another key focus is on the expansion of the electric mobility ecosystem with products, services and innovations. The range extends from intelligent charging services for the home as well as tailor-made services right through to home energy storage units, which work for example in conjunction with photovoltaics installed on house rooftops. Whether at home, at work or out on the road: intelligently networked charging solutions form an integral part, as customer acceptance in the area of electric mobility is closely associated with the availability of a comprehensive infrastructure.

Axel Harries, head of CASE at Daimler AG and as such head of the electric mobility think-tank, is all set to take up the seat on the Board of Directors at ChargePoint. In his opinion, collaboration with ChargePoint is an important building block: “While pursuing the systematic expansion of our CASE ecosystem based on our new product brand EQ, we also remain open and ready for partnerships and cooperation at the highest level.

Currently offering more than 33,000 charging spots at more than 7,000 sites around North America, ChargePoint is the world’s leading provider in the sector for electric mobility charging solutions and is the market leader in North America. With the increasing electrification of the drive system, demand for the company’s innovative charging solutions is increasing steadily, setting it on a course of steady growth. The international expansion of the business segment to the European market in particular is now on the agenda. “The automobile industry is at an inflection point, with more vehicles coming onto the market offering highly advanced electric powertrains than any other time in the world’s history,” said Pasquale Romano, CEO of ChargePoint. “ The significant investment by our lead investor Daimler and others not only underscores a collective commitment to e-mobility around the world, but will lay the groundwork for Europe’s most comprehensive charging network ever.”

Both the development and production of innovative infrastructure solutions for electric vehicles are among the company’s core competencies – from conventional AC charging through to ultra-fast charging via DC at up to 400 kW. ChargePoint offers solutions for every niche of the electric vehicle charging ecosystem, including commercial businesses, the retail trade, public institutions, fleet customers and individual drivers. Technologically, in Europe the company relies on the standardised Combined Charging System (CCS), with which it provides maximum compatibility for future electric vehicle models of all brands. All of the products from ChargePoint are networked via software and can be deployed for various customers in a variety of locations. In addition to charging stations, the US market leader also provides its customers with tailor-made cloud-based solutions – starting with user-specific energy management systems and well-proven payment services, as well as through to mobile apps boasting innovative features previously unavailable in the European market. Through remote monitoring and hotline support, ChargePoint ensures maximum availability of the charging stations around the clock, seven days a week – a decisive purchasing factor in particular for fleet operators of passenger cars, commercial vehicles or buses.

Daimler and ChargePoint are systematically pursuing the same goal: to promote the breakthrough of electric mobility through the targeted expansion of infrastructure and services. The collaboration between the two companies is the ideal supplement to the existing successful alliances and joint ventures of Daimler AG aimed at expanding an ecosystem for electric mobility. The companies will be embarking on their collaboration shortly.

The countdown to zero emission buses has started: towards the end of next year, Mercedes-Benz will be starting series production of a city bus with all-electric drive system based on the international best-seller, the Mercedes-Benz Citaro.

“Our city bus produces zero local emissions and is ultra-quiet through town. The engineers are currently undertaking thorough testing of prototypes of the new bus under the toughest of conditions. As the technical concept, which involves a modular system for the power supply as well as optimised thermal management, makes clear: the Citaro with battery-electric drive will set a new milestone”, says Hartmut Schick, Head of Daimler Buses.

Der Citaro mit vollelektrischem Antrieb durchläuft zurzeit den gleichen umfangreichen Test- und Erprobungszyklus wie jeder andere Omnibus von Mercedes-Benz. Prototypen haben zum Beispiel erfolgreich eine erste Wintererprobung bei eisigen Temperaturen am Polarkreis und eine Sommererprobung in der Hitze der spanischen Sierra Nevada absolviert.
The Citaro with all-electric drive is currently being put through the same comprehensive cycle of trials and testing to which every other bus built by Mercedes-Benz is subjected. Prototypes have, for example, already successfully undergone initial winter testing in icy temperatures at the Arctic circle as well as summer testing in the heat of Spain’s Sierra Nevada.

Modular design of battery packs allows range to be tailored

Mercedes-Benz celebrated production of the 50 000th Citaro just recently – but development of the world’s number one best-selling city bus continues apace. Hot on the heels of the recently introduced Citaro hybrid with its highly efficient diesel or gas-engine drive system comes the next step, the all-electric Citaro.

It receives its drive energy from lithium-ion batteries. The modular design of the battery pack means that individually customised solutions can be devised to match a wide range of applications and requirements in city traffic.

As well as the possibility of charging it from a power socket at the depot, Mercedes-Benz can also as an option supply the Citaro with one of a range of intermediate recharging solutions. The vehicle is powered by electric wheel hub motors at the rear axle, a system already proven over recent years in the Citaro G BlueTec Hybrid.

Thermal management reduces energy consumption dramatically

One of the particular features of the Citaro with all-electric drive will be the meticulously refined thermal management of the bus’s drive and climate control systems. This thermal management reduces energy consumption significantly and is tantamount to extending the range of the bus without changing the size of battery.

Successful testing in bitter cold as well as extreme heat

The Citaro with all-electric drive is currently being put through the same comprehensive cycle of trials and testing to which every other bus built by Mercedes-Benz is subjected. Prototypes have, for example, already successfully undergone initial winter testing in icy temperatures at the Arctic circle as well as summer testing in the heat of Spain’s Sierra Nevada. Endurance testing and detailed refinements will now follow, ensuring that Mercedes-Benz will be able to offer maximum availability on a par with that of a conventionally powered urban bus.

The Citaro with all-electric drive will celebrate its world premiere in September 2018 at the IAA Commercial Vehicles show in Hanover.

One of the most common complaints we receive is that Mercedes doesn’t bring their fuel efficient models to the U.S., but that is all about to change with their electric car lineup, including the all-new 2014 Mercedes-Benz B-Class Electric Drive.  Making its world debut at the New York International Auto Show last week, the Electric Drive offers a stylish design, luxury interior and a high-torque electric motor for completely emission-free driving.

Powerful and lively drive system

The new Mercedes-Benz B-Class Electric Drive is based on the conventionally powered B-Class, which has become a bestseller in many countries since its market debut in 2011. As a particularly versatile vehicle concept, the B-Class also allows environmentally friendly driving at the Mercedes level – with its innovative electric drive. In the USA, the vehicle will only be introduced with battery electric drive.

Quiet and locally emission-free drive power is provided by an electric motor with more than 134 hp (100 kW). Typically for an electric drive, the maximum torque of 228 lb.-ft. is available right from the first tap on the accelerator pedal – this roughly corresponds to the torque delivery of a modern gasoline engine with a displacement of 3.0 liters. This results in decidedly powerful acceleration from a standing start. For the standard sprint from 0 to 60 mph (100 km/h), the electric-powered B-Class requires less than ten seconds. This guarantees superior driving performance and highly dynamic, exhilarating driving pleasure in any situation.

The powerful lithium-ion battery is accommodated in the “Energy Space” in the vehicle’s underfloor – both space-saving and safe. Thanks to this intelligent packaging, the five-seater retains the familiar, generous interior and luggage space of the B-Class.

Emission-free even over longer distances

The maximum speed is electronically limited to 100 mph (160 km/h) – in the interests of operating range. The range is around 115 miles (200 kilometers), according to the respective driving cycle. This means that in addition to emission-free urban driving and short-range trips, longer journeys can also be undertaken without any problems, such as the distances covered on a daily basis by commuters. The battery of the B-Class Electric Drive can be recharged at any standard domestic power outlet. In the USA, the charging time for a range of about 60 miles (100 kilometers) is less than 2 hours at 240 V/40 A.

While the car is on the move, the electric drive itself contributes to a favorable energy balance by converting kinetic energy into electric current on the overrun and during braking, and feeds this energy into the battery (recuperation).

Dynamic Mercedes-Benz design

Refined sportiness together with visual appeal – the new B-Class Electric Drive is another example of the self-assured and dynamic Mercedes design, with powerful, tense lines and finely styled details. The front and rear sets the tone for the vehicle’s width, with a wide, prominent front grille, headlamps extending into the vehicle sides, a wide rear window, two-piece tail lamps and a large tailgate with a low loading sill. The side sill panels and striking bumpers with bar-shaped LED daytime running lamps exude dynamic. The charging socket is inconspicuously installed behind the charging flap.

Sporty interior with premium details

The interior underscores the high comfort standards of Mercedes-Benz. Highquality materials and finely structured surfaces, premium details, and precise finishing, emphasize the fact that electric driving is defined at a very high level according to the philosophy of Mercedes-Benz. The three large, round air vents in the center with their distinctively designed cross-form nozzles are sporty features that contribute to the emotional design language of the interior. Above the air vents is the display screen for the telematics system which appears to be free-floating – a modern, eye-catching feature of the cockpit.

When it comes to information and communication systems, the B-Class Electric Drive offers convenience and outstanding functionality that is signature luxury typical of Mercedes-Benz. Standard onboard features include the Audio 20 with a 14.7 cm color screen, a twin tuner, an MP3-capable CD player and a USB connection. Navigation is provided by the Becker® MAP PILOT. The multimedia system COMAND Online with internet access, navigation and voice control is available as an optional extra.

Functions specific to electric vehicles have been added to the instrumentation of the B-Class Electric Drive. A power display in the dial instrument has been added on the right. Its pointer rises in a clockwise direction from the green to the red area when power is being consumed, and drops below the zero line when the vehicle is feeding recuperative energy back into the battery.

Full connectivity

Its modern technology ensures that the B-Class Electric Drive is not only sustainable (locally emission-free) and agile (because of its high torque and acceleration), but also fully networked. Remote check-up and remote configuration of the vehicle is conveniently possible via the Vehicle Homepage. The driver can easily access his vehicle through the internet, using a PC or smartphone. In this way, it is possible to check the current charge status of the lithium-ion battery or to verify the vehicle’s current range on a map. The planned route can also be displayed, immediately showing whether and where the vehicle can be recharged along the way. The range of services for connectivity is rounded off with a pre-entry climate control option offering individually timed pre-heating or cooling. This advance air conditioning makes the B-Class Electric Drive the unrivalled benchmark in its segment.

Big on safety

Mercedes-Benz applies its familiar, high safety standards to the B-Class Electric Drive. Thanks to the innovative “Energy Space”, the battery is safely accommodated under the floor for crash protection. In addition, Mercedes-Benz already equips this innovative electric car with the radar-based accident warning system COLLISION PREVENTION ASSIST with adaptive Brake Assist as standard. This assistance system gives the driver a visual and acoustic warning of recognized obstacles, prepares him for braking action and assists him with the braking process as the situation requires. In this way it significantly reduces the danger of a rear-end collision. Additionally, more modern driver assistance systems are available – among them Blind Spot Assist, Lane Keeping Assist and Active Park Assist.

Electric driving made by Mercedes-Benz

Locally emission-free electric vehicles such as the new B-Class Electric Drive are a major part of the Mercedes-Benz strategy for sustainable mobility. The Stuttgart-based premium manufacturer is reasserting its claim to leadership in this sector with electric cars which are fully suitable for everyday use. These include the B-Class F-CELL, and the SLS AMG Coupé Electric Drive (TBD for USA). The smart fortwo electric drive which launched last year in Europe received a positive response from customers. Since the middle of last year, much more than 1,000 vehicles have been produced and delivered. The all-new smart fortwo electric drive will be available in U.S. stores beginning May 1, 2013. The new B-Class Electric Drive will be available in the USA from early 2014 and then the European launch will follow.

Preliminary Technical Data

The future of electric driving celebrated its world premiere this morning at the 2013 New York International Auto Show: the Mercedes-Benz B-Class Electric Drive makes its debut with a dynamic design, high-quality interior and a high-torque electric motor for local emission-free driving. This makes for lively and effortless driving pleasure over a range of around 115 miles. In addition, the B-Class Electric Drive is digitally networked meaning it can be conveniently checked and configured via the internet. As a true Mercedes it also sets high standards in terms of comfort, quality and safety. Bearing the Mercedes star as an unmistakable trademark, the B-Class Electric Drive will be launched first in the USA at the beginning of 2014, where it will be the first luxury battery electric car from Mercedes-Benz in the market.

The new B-Class Electric Drive surprises with a particularly dynamic driving experience, delivering decidedly powerful acceleration while gliding along the road practically silently. The driver and passengers in this new electric Mercedes will enjoy the familiar comfort of a well designed, high-quality interior offering a generous amount of space. The B-Class Electric Drive thus combines dynamism and driving pleasure with zero local emissions – in short, electric driving at the premium level.

According to Dr. Joachim Schmidt, member of the Mercedes-Benz Cars Board of Management responsible for Sales and Marketing: “The B-Class Electric Drive meets the wishes of many customers for emission-free driving without foregoing the hallmark attributes of a Mercedes-Benz, namely safety, comfort and, of course, not to forget exhilarating driving pleasure.”

The new Mercedes B-Class Electric Drive will be availabe in the U.S. early next year but pre-orders will likely make it sold out for quite a while so place your order early if you want one.

Technical data*

Mercedes AMG released the latest Tron inspired video of the SLS AMG Coupé Electric Drive, perfect inspiration for those having trouble working through this rather dreary Friday.  Once you’ve watched the video, skip down to the photo gallery for a complete overview of the car from every angle.

First show at the Paris Motor Show, Mercedes presented the public with the all-electric SLS setting the stage to become the fastest production electric supercar in the world.

When designing the Mercedes SLS AMG Coupé Electric Drive, Mercedes AMG took a few styling tips from the F1 racing world. In addition to the body and drivetrain that uses F1 technology, AMG designers also adopted the racing rule of beginning with the the drive engineering and working their way out. In this case, the electric drivetrain is the focus of the SLS AMG.Acting as the car’s spine, the battery is located within a carbon-fiber monocoque, around that is the aluminum spaceframe body.. Keeping the center of gravity low, the battery compartment is near to the ground and spread along the length of the car to keep the weight evenly distributed.

Press Release

The key data at a glance:

• SLS AMG Coupé Electric Drive
• Max. output 552 kW
• Torque 1000 Nm
• 0 – 100 km/h 3.9 s
• Range 250 km (according to NEDC combined)
• Battery energy content 60 kWh
• Battery voltage 400 volts

The locally emission-free super sports car featurs advanced technology from the world of Formula 1 and is the most exclusive and dynamic way in which to drive an electric car. The most powerful AMG high-performance vehicle of all time, the SLS AMG Coupe Electic Drive has four electric motors producing a total output of 552 kW and a maximum torque of 1000 Nm, resulting in a 0-62 mph sprint in 3.9 seconds. The cost for the SLS AMG Coupe and its one of a kind electric drive, 416,500 Euros ($538,326 based on 9/28/12), with gas prices hitting nearly $5.00 a gallon in California this week, the savings will pile up very quickly.

Mercedes SLS AMG Coupe Electric Drive

A new dimension of driving performance – a convincing synonym for the AMG brand promise are the outstanding driving dynamics which come courtesy of AMG Torque Dynamics as well as torque distribution to individual wheels, which is made possible by means of wheel-selective all-wheel drive. The most “electrifying” gullwing model ever has been developed in-house by Mercedes-AMG GmbH. The high-voltage battery for the SLS AMG Coupé Electric Drive is the result of cooperation between Mercedes-AMG and Mercedes AMG High Performance Powertrains in Brixworth (GB). This is an area in which the British Formula 1 experts were able to contribute their extensive know-how with KERS hybrid concepts.

“The SLS AMG Coupé Electric Drive is setting new standards for cars with electric drives. As the most powerful gullwing model ever, it is also representative of the enduring innovational strength of Mercedes-AMG. Our vision of the most dynamic electric vehicle has become a reality. With the help of our colleagues at Mercedes AMG High Performance Powertrains in Brixworth, we are bringing exciting advanced technology from the world of Formula 1 to the road”, according to Ola Källenius, Chairman of the Board of Management of Mercedes-AMG GmbH.

Pioneering, visionary, electrifying: the powerful and locally emission-free super sports car with electric drive also embodies the development competence of Mercedes-AMG GmbH. With this innovative and unique drive solution, AMG – as the performance brand of Mercedes-Benz – is demonstrating its technological leadership in this segment. The SLS AMG Coupé Electric Drive is aimed at technology-minded super sports car fans who are open to new ideas and enthusiastic about ambitious high-tech solutions for the future of motoring.

Mercedes SLS AMG Coupe Electric Drive

Enormous thrust thanks to 1000 Nm of torque

The pioneering drive package in the SLS AMG Coupé Electric Drive is impressive and guarantees a completely innovative and electrifying driving experience: enormous thrust comes courtesy of four synchronous electric motors providing a combined maximum output of 552 kW and maximum torque of 1000 Nm. The very special gullwing model accelerates from zero to 100 km/h in 3.9 seconds, and can reach a top speed of 250 km/h (electronically limited). The agile response to accelerator pedal input and the linear power output provide pure excitement: unlike with a combustion engine, the build-up of torque is instantaneous with electric motors – maximum torque is effectively available from a standstill. The spontaneous build-up of torque and the forceful power delivery without any interruption of tractive power are combined with completely vibration-free engine running characteristics.

The four compact permanent-magnet synchronous electric motors, each weighing 45 kg, achieve a maximum individual speed of 13,000 rpm and in each case drive the 4 wheels selectively via a axially-arranged transmission design. This enables the unique distribution of torque to individual wheels, which would normally only be possible with wheel hub motors which have the disadvantage of generating considerable unsprung masses.

Mercedes SLS AMG Coupe Electric Drive

Typical AMG: the sound of the 21st century

Powerful, voluminous, dynamic, emotional and authentic: the characteristic sound of the SLS AMG Coupé Electric Drive embodies the sound of the 21st century. After an elaborate series of tests as well as numerous test drives, the AMG experts have created a sound which captures the exceptional dynamism of this unique super sports car with electric drive. Starting with a characteristic start-up sound, which rings out on pressing the “Power” button on the AMG DRIVE UNIT, the occupants can experience a tailor-made driving sound for each driving situation: incredibly dynamic when accelerating, subdued when cruising and as equally characteristic during recuperation. The sound is not only dependent on road speed, engine speed and load conditions, but also reflects the driving situation and the vehicle’s operating state with a suitable driving noise. Perfect feedback for the driver is guaranteed thanks to a combination of the composed sound, the use of the vehicle’s existing inherent noises and the elimination of background noise – this is referred to by the experts as “sound cleaning”. The impressive sound comes courtesy of the standard sound system with eleven loudspeakers.

Advanced Formula 1 technology: high-voltage lithium-ion battery

Battery efficiency, performance and weight: in all three areas Mercedes-AMG is setting new standards. The high-voltage battery in the SLS AMG Coupé Electric Drive boasts an energy content of 60 kWh, an electric load potential of 600 kW and weighs 548 kg – all of which are absolute best values in the automotive sector. The liquid-cooled lithium-ion high-voltage battery features a modular design and a maximum voltage of 400 V.

Advanced technology and know-how from the world of Formula 1 have been called on during both the development and production stages: the battery is the first result of the cooperation between Mercedes-AMG GmbH in Affalterbach and Mercedes AMG High Performance Powertrains Ltd. Headquartered in Brixworth in England, the company has been working closely with Mercedes-AMG for a number of years. F1 engine experts have benefited from its extensive expertise with the KERS hybrid concept, which made its debut in the 2009 Formula 1 season. At the Hungarian Grand Prix in 2009, Lewis Hamilton achieved the first historic victory for a Formula 1 vehicle featuring KERS hybrid technology in the form of the Mercedes-Benz KER System. Mercedes AMG High Performance Powertrains supplies the Formula 1 teams MERCEDES AMG PETRONAS, Vodafone McLaren Mercedes and Sahara Force India with Mercedes V8 engines and the KERS.

The high-voltage battery consists of 12 modules each comprising 72 lithium-ion cells. This optimised arrangement of a total of 864 cells has benefits not only in terms of best use of the installation space, but also in terms of performance. One technical feature is the intelligent parallel circuit of the individual battery modules – this helps to maximise the safety, reliability and service life of the battery. As in Formula 1, the battery is charged by means of targeted recuperation during deceleration whilst the car is being driven.

High-performance 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 the 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 optimum operating temperature with the aid of an electric heating element. In extremely high external temperatures, the cooling circuit for the battery can be additionally boosted with the aid of the air conditioning. This also helps to preserve the overall service life of the battery system.

Quick charge function via special wall box

Ideally the SLS AMG Coupé Electric Drive is charged with the aid of a so-called wall box. Installed in a home garage, this technology provides a 22 kW quick-charge function, which is the same as the charging performance available at a public charging station. A high-voltage power cable is used to connect the vehicle to the wall box, and enables charging to take place in around three hours. Without the wall box, charging takes around 20 hours. The wall box is provided as an optional extra from Mercedes-AMG in cooperation with SPX and KEBA, two suppliers of innovative electric charging infrastructures for the automotive industry.

Eight-stage design for maximum safety

To ensure maximum safety, the SLS AMG Coupé Electric Drive makes use of an eight-stage safety design. This comprises the following features:

1. all high-voltage cables are colour-coded in orange to prevent confusion

2. comprehensive contact protection for the entire high-voltage system

3. the lithium-ion battery is liquid-cooled and accommodated in a high-strength aluminium housing within the carbon-fibre zero-intrusion cell

4. conductive separation of the high-voltage and low-voltage networks within the vehicle and integration of an interlock switch

5. active and passive discharging of the high-voltage system when the ignition is switched to “off”

6. in the event of an accident, the high-voltage system is switched off within fractions of a second

7. continuous monitoring of the high-voltage system for short circuits with potential compensation and insulation monitors

8. redundant monitoring function for the all-wheel drive system with torque control for individual wheels, via several control units using a variety of software

By using this design, Mercedes-AMG ensures maximum safety during production of the vehicle and also during maintenance and repair work. Of course the SLS AMG Coupé Electric Drive also meets all of the statutory and internal Mercedes crash test requirements.

All-wheel drive with AMG Torque Dynamics enables new levels of freedom

Four motors, four wheels – the intelligent and permanent all-wheel drive of the SLS AMG Coupé Electric Drive guarantees driving dynamics at the highest level, while at the same time providing the best possible active safety. Optimum traction of the four driven wheels is therefore ensured, whatever the weather conditions. According to the developers, the term “Torque Dynamics” refers to individual control of the electric motors, something which enables completely new levels of freedom to be achieved. The AMG Torque Dynamics feature is permanently active and allows for selective distribution of forces for each individual wheel. The intelligent distribution of drive torque greatly benefits driving dynamics, handling, driving safety and ride comfort. Each individual wheel can be both electrically driven and electrically braked, depending on the driving conditions, thus helping to:

• optimise the vehicle’s cornering properties
• reduce the tendency to oversteer/understeer
• increase the yaw damping of the basic vehicle
• reduce the steering effort and steering angle required
• increase traction
• and minimise ESP® and ASR intervention

The AMG Torque Dynamics feature boasts a great deal of variability and individuality by offering three different transmission modes:

Comfort (C): comfortable, forgiving driving characteristics

Sport (S): sporty, balanced driving characteristics

Sport plus (S+): sporty, agile driving characteristics

AMG Torque Dynamics enables optimum use of the adhesion potential between the tyres and the road surface in all driving conditions. The technology allows maximum levels of freedom and as such optimum use of the critical limits of the vehicle’s driving dynamics. Outstanding handling safety is always assured thanks to the two-stage Electronic Stability Program ESP®.

“AMG Lightweight Performance” design strategy

The trailblazing body shell structure of the SLS AMG Coupé Electric Drive is part of the ambitious “AMG Lightweight Performance” design strategy. The battery is located within a carbon-fibre monocoque which forms an integral part of the gullwing model and acts as its “spine”. The monocoque housing is firmly bolted and bonded to the aluminium spaceframe body. The fibre composite materials have their roots in the world of Formula 1, among other areas. The advantages of CFRP (carbon-fibre reinforced plastic) were exploited by the Mercedes-AMG engineers in the design of the monocoque. 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. Carbon-fibre 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 weight advantages achieved through the carbon-fibre battery monocoque are reflected in the agility of the SLS AMG Coupé Electric Drive and, in conjunction with the 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.

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.

Optimum weight distribution and low centre of gravity

The purely electric drive system was factored into the equation as early as the concept phase when the super sports car was being developed. It is ideally packaged for the integration of the high-performance, zero-emission technology: by way of 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-voltage battery. Advantages of this solution include the vehicle’s low centre of gravity and balanced weight distribution – ideal conditions for optimum handling, which the electrically-powered gullwing model shares with its petrol-driven sister model.

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 Coupé Electric Drive features an independent multi-link suspension with pushrod damper struts. This is because the vertically-arranged damper struts 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 world of motorsport, the agility and driving dynamics of the SLS AMG Coupé Electric Drive 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 SLS AMG Coupé Electric Drive is slowed with the aid of AMG high-performance ceramic composite brakes, which boast direct brake response, a precise actuation point and outstanding fade resistance, even in extreme operating conditions. The over-sized discs – measuring 402 x 39 mm at the front and 360 x 32 mm at the rear – are made of carbon fibre-strengthened ceramic, feature an integral design all round and are connected to an aluminium bowl in a radially 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 tyre grip. The lower rotating masses at the front axle also ensure a more direct steering response – which is particularly noticeable when taking motorway bends at high speed.

Exclusive, high-quality design and appointments

Visually, the multi-award-winning design of the SLS AMG is combined with a number of specific features which are exclusive to the Electric Drive variant. The front apron has a striking carbon-look CFRP front splitter which generates downforce on the front axle. The radiator grille and adjacent air intakes adorn special areas painted in the vehicle colour and with bionic honeycomb-shaped openings. They are not only a visual highlight but, thanks to their aerodynamically optimised design, also improve air flow over the cooling modules mounted behind them. Darkened headlamps also impart a sense of independence to the front section. Viewed from the side, the “Electric Drive” lettering stands out on the vehicle side, as do the AMG 5-twin-spoke light-alloy wheels with their specific paint design. The SLS AMG Electric Drive comes as standard with 265/35 R 19 tyres on the front and 295/30 R 20 tyres on the rear. The overall look is rounded off to dynamic effect by the new diffuser-look rear apron, and the darkened rear lamps. One feature reserved exclusively for the SLS AMG Coupé Electric Drive is the “AMG electricbeam magno” matt paint finish. A choice of five other colours is available at no extra cost.

When the exterior colour AMG electricbeam magno is chosen, the high-quality, sporty interior makes use of this body colour for the contrasting stitching – the stitching co-ordinates perfectly with designo black Exclusive leather appointments. AMG sports seats and numerous carbon-fibre trim elements in the interior underscore the exclusive and dynamic character of what is currently the fastest electric car. Behind the new AMG Performance steering wheel there is a newly designed AMG instrument cluster: instead of a rev counter, there is a power display providing information on the power requirements, recuperation status, transmission modes and battery charge.

AMG Performance Media as standard

The AMG DRIVE UNIT comprises the electronic rotary switch for selecting the three transmission modes of “C” (Controlled Efficiency), “S” (Sport) and “S+” (Sport plus), which the driver can use to specify different performance levels from the electric motors, which in turn also changes the top speed and accelerator pedal response. Behind the buttons for “power” and “ESP On/Off”, there are also buttons for AMG Torque Dynamics and AMG Setup.

In addition to carbon-fibre exterior mirrors, AMG carbon-fibre engine compartment cover, COMAND APS, Media Interface, Blind Spot Assist and reversing camera, the standard equipment also includes the AMG Performance Media system. Besides full high-speed mobile internet access, the system provides information on engine performance, lateral and longitudinal acceleration, tyre pressure, vehicle setup and lap times, as well displaying a variety of additional information such as:

• vehicle energy flow
• battery charge status
• burrent range
• AMG Torque Dynamics
• temperatures of the battery and motors
• energy consumption kWh/100 km

The Mercedes-Benz SLS AMG Coupé Electric Drive will be celebrating its market launch in 2013. The price in Germany (incl. 19% VAT) will be:

SLS AMG Coupé Electric Drive: 416,500 euros

Global automakers from the United States and Germany are demonstrating a new fast-charging technology that will give electric vehicle owners the ability to recharge their EV in a mere 15-20 minutes. Audi, BMW, Chrysler, Daimler, Ford, General Motors, Porsche and Volkswagen have all agreed to support a single-port fast charging approach, called DC-fast charging, for use on electric vehicles in Europe and the United States.

The combined charging system integrates one-phase AC-charging, fast three-phase AC-charging, DC-charging at home and ultra-fast DC-charging at public stations into one vehicle inlet. The new system gives EV owners the ability to charge at most existing charging stations regardless of power source and may speed more affordable adoption of a standardized infrastructure. The combined charging approach will also reduce development and infrastructure complexity, improve charging reliability, reduce the total cost-of-ownership for end customers and provide low maintenance costs.

Currently today’s electric vehicles like the Ford Focus Electric can recharge in as little as four hours with a quick charger, but new models like the 2014 BMW i3 will be able to be recharged much faster. The new chargers will be available commercially by the end of 2012 and the first vehicles to use the new technology will be available starting in 2013.

Global Automakers to Demo EV Fast Charging at EVS26

• Combined Charging System allows AC and DC fast-charging from single inlet port

Global automakers from the United States and Germany will demonstrate fast-charging technology that will enable the recharging of most electrified vehicles with compatible systems in as little as 15-20 minutes.

Audi, BMW, Chrysler, Daimler, Ford, General Motors, Porsche and Volkswagen have agreed to support a harmonized single-port fast charging approach – called DC Fast Charging with a Combined Charging System – for use on electric vehicles in Europe and the United States.

Live charging demonstrations will be conducted during the Electric Vehicle Symposium 26 (EVS26) May 6-9.

The combined charging system integrates one-phase AC-charging, fast three-phase AC-charging, DC-charging at home and ultra-fast DC-charging at public stations into one vehicle inlet. This will allow customers to charge at most existing charging stations regardless of power source and may speed more affordable adoption of a standardized infrastructure.

The International Society of Automotive Engineers (SAE) has chosen the Combined Charging System as the fast-charging methodology for a standard that incrementally extends the existing Type 1-based AC charging. The standard is to be officially published this summer. ACEA, the European association of vehicle manufacturers has also selected the Combined Charging System as its AC/DC charging interface for all new vehicle types in Europe beginning in 2017.

The charging system design was based on collaborative reviews and analysis of existing charging strategies, the ergonomics of the connector and preferences of U.S. and European customers. The system was developed for all international vehicle markets and creates a uniform standard with identical electrical systems, charge controllers, package dimensions and safety mechanisms.

The system maximizes capability for integration with future smart grid developments through common broadband communication methods regardless of the global location of the charging system. The combined charging approach will reduce development and infrastructure complexity, improve charging reliability, reduce the total cost-of-ownership for end customers and provide low maintenance costs.

Commercially available combined charging units are projected to be available later this year. All committed OEMs have vehicles in development which will use the Combined Charging System. The first vehicles to use this system will reach the market in 2013.

At this year’s international Art Directors Club awards, smart won “gold” in the category of “Interactive/ Physical Innovations” with its interactive eball game.

In technical terms, smart eball is an interactive game that shows off the dynamism and agility of the electrically driven smart fortwo. But one look at the game and you are instantly taken back to the ’70s when Pong was the latest and greatest in the gaming world. In Pong, it was a a tennis sports game featuring simple two-dimensional graphics, eball is a similar ping pong-like game that uses digital bats to knock the ball back and forth on LED screens. The digital bats are moved by driving two actual smart fortwo electric drives forward and back while being monitored with the aid of a laser measuring and transmission technology system.

“We wanted participants to experience the incredible driving fun of the electric smart and smart eball achieved that perfectly,” says Dr. Annette Winkler, Head of smart. “The aim of the game was understood immediately and anyone can just dive straight in – it’s just as intuitive and straightforward as our smart electric drive.”

The eball game was also used at the world premiere of the smart fortwo electric drive at the 2011 International Motor Show in Frankfurt and was enjoyed enthusiastically by all. In total, more than 1,500 games of eball have been played and the number is still on the rise.

The 91st ADC Awards ceremony will be held at a large gala in New York on May 8th.

With the electric drivetrain system of the SLS AMG E-CELL, Mercedes-AMG GmbH is providing yet another glimpse of its latest development project. The drivetrain has been in development since 2010 as a result of the cooperation between Mercedes-AMG and Mercedes AMG High Performance Powertrains in Brixworth. Four synchronous electric motors located near the wheels, providing a peak output of 392 kW and torque of 880 Nm, help to provide the SLS AMG E-CELL with its exciting driving dynamics. The carbon-fibre transmission tunnel, which also serves as the monocoque housing for the high-voltage battery modules, is structurally integrated into the aluminium body shell and firmly bonded to it. The lightweight fibre composite materials have their origins in the world of Formula 1, among other areas.

A small series-production run of the Mercedes-Benz SLS AMG E-CELL is expected to be launched onto the market in 2013. The powerful and locally emission-free super sports car with electric drive is yet another example of the innovative strength and development competence of the AMG performance brand.

The ground-breaking drive system of the technology vehicle boasts some outstanding features: powerful traction is provided by four synchronous electric motors with a combined peak output of 392 kW and a maximum torque of 880 Nm. The four compact electric motors each achieve a maximum rotational speed of 12,000 rpm and are positioned close to 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 100 km/h in 4 seconds

When it comes to dynamics, the electrically-powered SLS makes a statement: the gullwing model accelerates from zero to 100 km/h in 4 seconds – which almost puts it on the same high level as the SLS AMG with 6.3-litre V8 engine developing 420 kW (571 hp), which can accelerate to 100 km/h in 3.8 seconds.

Further exciting touches are provided courtesy of the agile accelerator response and the straight-line performance: unlike a combustion engine, torque build-up in an electric motor is instantaneous – maximum torque is available virtually from a standstill. The spontaneous torque build-up and confident power delivery – which does not suffer from any interruption of tractive power – are combined with engine running characteristics which are totally free of vibration.

The key data at a glance:

All-wheel drive with torque vectoring enables completely new levels of freedom

Four wheels, four motors – 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. Optimum traction is therefore ensured, whatever the weather conditions. According to the AMG developers, “torque vectoring” involves the individual control of the electric motors, something which enables completely new levels of freedom to be achieved. Torque vectoring is permanently active and allows for selective distribution of forces for each individual wheel. The intelligent distribution of drive torque greatly benefits driving dynamics, handling, driving safety and ride comfort. Each individual wheel can be electrically driven and electrically braked, depending on the driving conditions, thus helping to

• optimise the vehicle’s cornering properties
• reduce the tendency to oversteer/understeer
• increase the yaw damping of the basic vehicle
• reduce the steering effort and steering angle required
• increase traction
• and minimise ESP® intervention

Torque vectoring enables optimum use of the adhesion potential between the tyres and the road surface in all driving conditions, thereby extending the critical limits of the vehicle’s driving dynamics.

Advanced technology from Formula 1: high-voltage lithium-ion battery

The SLS AMG E-CELL incorporates a liquid-cooled high-voltage lithium-ion battery featuring a modular design with an energy content of 48 kWh. Its development has made use of advanced technology from the world of Formula 1: the battery is the first result of the co-operation between Mercedes-AMG GmbH in Affalterbach and Mercedes AMG High Performance Powertrains (formerly Mercedes-Benz High Performance Engines). Headquartered in Brixworth, England, the company has been working closely with AMG for a number of years. F1 engine experts have benefited from its extensive expertise with the KERS hybrid concept, which made its debut in the 2009 Formula 1 season. At the Hungarian Grand Prix in 2009, Lewis Hamilton achieved the first historic victory for a Formula 1 vehicle featuring KERS hybrid technology in the form of the Mercedes-Benz KER System.

The high-voltage battery consists of 12 modules each comprising 72 lithium-ion polymer cells. This optimised arrangement of a total of 864 cells has benefits not only in terms of best use of the installation space, but also in terms of performance. The maximum electric load potential of the high-voltage battery is 480 kW, which is an absolute best value 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 maximise the safety, reliability and service life of the battery. As in Formula 1, the 400-volt battery is charged by means of targeted recuperation during braking whilst the car is being driven.

High-performance 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.

“AMG Lightweight Performance” design strategy

The trailblazing body shell structure of the SLS AMG E-CELL is part of the ambitious “AMG Lightweight Performance” design strategy. The battery is located within a carbon-fibre monocoque which forms an integral part of the body shell and acts as the gullwing model’s “spine”.

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 AMG Black Series vehicles 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.

Optimum weight distribution and low centre of gravity

The purely electric drive system was factored into the equation as early as the concept phase when the gullwing model was being developed. It is ideally packaged for the integration of the high-performance, zero-emission technology: by way of 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-voltage battery. Advantages of this solution include the vehicle’s low centre of gravity and balanced weight distribution – ideal conditions for optimum handling, which the electrically-powered gullwing model shares with its petrol-driven sister model.

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 world of motorsport, the agility and driving dynamics of the SLS AMG E-CELL 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 technology vehicle is slowed with the aid of AMG high-performance ceramic composite brakes, which boast extremely short stopping distances, a precise actuation point and outstanding fade resistance, even in extreme operating conditions. The over-sized discs – measuring 402 x 39 mm at the front and 360 x 32 mm at the rear – are made of carbon fibre-strengthened ceramic, feature an integral design all round and are connected to an aluminium bowl in a radially 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 tyre grip. The lower rotating masses at the front axle also ensure a more direct steering response – which is particularly noticeable when taking motorway bends at high speed. The ABS and ESP® systems have been adapted to match the special application spectrum of the permanent all-wheel drive.

Mercedes-Benz claims that its new F-Cell B-Class is invisible to the environment with 0.0 emissions.  To drive this idea home, Mercedes fitted the Fuel Cell powered B-Class with a LED panel on one side and a Canon EOS 5D Mark II camera on the other, with the camera continuously shooting live video of its surroundings and projecting it instantly on the F-Cell’s screen.  The result:  a nearly invisible Mercedes F-Cell B-Class.

The technology isn’t perfect, but impressive none-the-less, especially at night.  Take the minute and a half and watch the video below.

The smart “for-us” will no doubt turn heads at this years Detroit Auto Show,(North American International Auto Show at Detroit’s Cobo Center, open to the public January 14-22, 2012) challenging visitor’s ideas about what today’s urban pick-up might look like.  smart CEO Dr. Annette Winkler says, “We at smart love pickups – if they are small on the outside, large on the inside, very safe and extremely comfortable. With the smart for-us, a petrol station is no longer needed.”  After seeing the smart for-us in person for the first time, smart has done an amazing job reinventing the pick-up and the way we look at pick-ups.

For the first time, the smart for-us translates the practical load layout of a pickup to the reality of 21st century urban traffic. With its small outside dimensions, it could almost go unnoticed in the bed of a typical American pickup. Under the body, it’s anything but ordinary: the for-us is agile and lively to drive, with state-of-the-art all-electric power from a 55- kilowatt magneto-electric motor.

The smart for-us has plenty of room for two people and behind them two slits in the cargo bed for the front wheels of two smart ebikes. Electric bikes are range-extending in two respects; The convenient docking station in the cargo bed ensures that the ebike batteries are always charged, and from a trip into town to a nature preserve outing, the smart ebikes enable smart for-us passengers to reach destinations that are out of bounds for cars – for example, park trails and restricted zones in cities.

a sassy, powerful design

Even a first glance at the design study reveals a new capability, yet the for-us remains true to the smart brand – surprising, sassy and capable. With its high-contrast tridion safety cell, the for-us is the epitome of smart. At the same time, the for-us pickup makes a powerful design statement, playing on the macho image of conventional mega-pickups. It greets viewers with a friendly, confident face and with a convex, sensuous body shape. The bold look, complete with a smart emblem on the grille and an underride guard that finishes off the front end, is complemented by body panels which are high-gloss metallic white, while the tridion safety cell has a contrasting textured grey finish.

ready to reach mountain bike terrain

The for-us sits about two inches higher than a production smart fortwo, suggesting it’s ready for off-road driving, for example, to reach mountain bike terrain. At the same time, its extremely short front and rear overhangs make it relatively small overall. When its power tailgate opens, the cargo floor retracts 11 inches, making the three-foot cargo area easy to access.

Its wheelbase is 97.7 inches, about two feet longer than the well-known fortwo. Overall, the for-us is 139.6 inches in length, nearly three feet longer than the fortwo, and to emphasize its sturdy look, the track is two inches wider. The smart for-us rolls on Michelin 235 / 55 R18 off-road tires mounted on three-spoke wheels with eye-catching fold-out wing nuts that serve to loosen the wheel nuts.

Its parallelogram front and rear lights are striking, with outer rings that serve as turn signals and a row of rod-shaped LEDS for daytime running lights. The arrow-shaped lights are reminiscent of drops streaming across an airplane window as it takes off. The modular tail lights can even be opened, revealing storage space for the charging cable or water bottles.

an interior that’s stylish, functional and uncomplicated

Inside, the cockpit design boasts aerodynamic design for exceptional interior ventilation, with taut surfaces in mother-of-pearl white contrasting with brushed aluminum working parts. Stylish yet uncomplicated, the two seats in the concept car are perfectly smart – highly functional and easy to customize. Open in the middle, the seat shells are covered with an easily removable yellow fabric, giving them a hammock-like seating feel. The soft yellow seat covers include a deep embossed silver hexagon pattern that emphasizes the car’s dynamic look. Instead of a conventional rear-view mirror, an integrated video camera displays the area behind the car on a smart phone that’s mounted on a special bracket above the dash.

zero-emission driving fun

The electric drive of the smart for-us is based on the new fortwo electric drive model, which will launch in the fall of 2012. Thanks to its 55-kilowatt magneto-electric motor, the smart for-us is nimble and lively to drive.

With 96 pound-feet of torque, the for-us boasts powerful, responsive acceleration and a top speed well over 80 mph. Its state-of-the-art lithium-ion battery has a capacity of 17.6 kilowatt-hours of electric power. The battery can be recharged from 20 to 80 percent in only 3½ hours, and a full charge takes no more than eight hours.

also the debut of the smart ebike

The world premiere of the smart for-us concept pickup also marks the debut of the smart ebikes displayed on its cargo bed. As expected, the ebikes are unconventional in design, with high-technology, high-performance parts such as Magura MT4 disc brakes and a USB connector for infotainment devices.

Strictly speaking, the smart ebike is a hybrid – as soon as the rider begins to pedal, a Bionx rear-wheel hub motor begins to help out. The 250-watt brushless, maintenance-free motor can provide a choice of four power levels, and its battery can last for more than 60 miles. Pedal power is transmitted to the rear wheel by a quiet, durable belt drive, while a threespeed gear hub provides simple gear changes.

When I hear the term “urban pickup”, images of the Clampetts fresh off a new oil discovery immediately come to mind. smart, however, had a slightly different vision of what an urban pickup should be and they called it the for-us.  It is designed for the young and those that still think they are young with active lifestyles that are conscious of the footprint they are leaving behind.  Don’t confuse low emission driving with small and slow, the smart for-us is designed to have a practical loading concept that helps to maximize interior space.  The for-us  also has a state-of-the-art electric drive with a55 kW magneto-electric motor that gives the driver a speedy response.

smart is turning the automotive world upside down once again and challenging ideas about what an urban pickup should look like. In a tongue-in-cheek manner the for-us signals that this is the right car for the young and young-at-heart with active lives who attach importance to low emissions and taking up minimum road space. The smart for-us translates the practical loading concept of a pickup to the reality of 21st century urban traffic for the first time.

With its exterior dimensions (length/width/height: 3547/1506/1701mm) it could almost go unnoticed on the loading area of a typical pickup, and it also anything but ordinary under the body. Thanks to the state-of-the-art electric drive with a55 kW magneto-electric motor the zero-emission smart for-us is agile and lively to drive. It will celebrate its world premiere at the North American International Auto Show in Detroit (January 14-22, 2012).

smart CEO Dr. Annette Winkler says “We at smart love pick-ups – if they are small on the outside, large on the inside, very safe and extremely comfortable. With the smart for-us a petrol station is no longer required!”

Like car2go, the globally successful car sharing initiative from smart for more flexibility in city traffic, the smart for-us is a mobility concept. It has plenty of room for two people and space for two smart ebikes behind them. Thanks to the docking station on the cargo area of the smart for-us their batteries are always charged, and smart for-us drivers can also reach destinations that are out of bounds for cars – for example traffic-calmed zones in the city or isolated park trails.

The design: sassy and robust with extremely short overhangs

Compared with the series-produced fortwo the smart for-us makes a powerful statement and its appearance plays with the martial image of conventional mega-pickups. Nevertheless, it greets the viewer with a friendly yet assertive face. It features convex and sensuously shaped body surfaces. The large brand emblem is proudly sported on the grille, and the front has a pronounced three-dimensional design with an underride guard finishing off the lower part of the front end.

The longer wheelbase (2480 mm/plus 613 mm) and the track that has been widened by 50 mm on each side also emphasise the robust look of the study. At the same time the extremely short overhangs at the front and rear make it exceedingly compact.

The tailboard at the rear of the smart for-us is electrically driven. When it opens first of all the cargo floor including tailboard retracts by 280 mm, then the tailgate slides down in a parallel position. The cargo on the 900 mm cargo area is then extremely easy to access.

Sleek, taut surfaces in mother-of-pearl white combined with precisely designed technical functional elements in brushed aluminium – the interior is characterised by contrasts. Like in the smart forvision, the whole cockpit boasts aerodynamic styling for interior ventilation. In place of a conventional rear-view mirror the smart for-us features a smartphone accommodated in a holder on top of the instrument panel support. The driver can see what is happening on the road behind with the help of an integrated video camera.

Stylish, uncomplicated, highly functional and easy to individualise – the two seats in the concept car are typically smart. The seat shells, which are open in the middle, are covered with a soft yellow fabric throw giving them a hammock-like seating feel.

Electric drive – zero-local-emission driving fun

The electric drive of the smart for-us is based on the innovative drive concept of the smart fortwo electric drive, which will be launched in the spring of 2012. Thanks to the 55 kW magneto-electric motor the smart for-us is agile and lively to drive. With 130 Newton metres of torque it boasts powerful, lag-free acceleration and it can overtake other vehicles with the greatest of ease. The maximum speed exceeds 120 km/h. The lithium-ion battery has capacity of 17.6 kWh.

Mercedes-Benz unveiled their Concept B-Class E-Cell Plus at the Frankfurt International Motor Show for the press on Tuesday.

The Mercedes Concept B-Class E-Cell Plus has a total range of up to 600 kilometers and a range of up to 100 kilometers when in all-electric, local emission-free mode. Acceleration in the B-Class E-Cell Plus is a less then speedy sprint from 0 to 100 km/h in approximately 11 seconds and the top speed of 150 km/h.  Though you won’t win any races both speeds are attainable in either operating mode making it extremely eco-friendly.

The above 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 it serves as a driving engine, acting on the front wheels together with the electric motor via a newly developed automatic transmission. The transmission is a newly developed automatic from Mercedes-Benz.

The Mercedes 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.

Complete details can be found in the expanded press release below.

Making its world debut at the 2011 Frankfurt Motor Show in a couple of days, the BRABUS ZERO EMISSION project vehicle Hybrid is a combination of the best of two worlds. An efficient direct-injection diesel with BRABUS ECO tuning and two electric wheel hub motors, this car is an innovative hybrid version of the Mercedes E 220 CDI BlueEFFICIENCY known for its outstanding fuel economy ex-factory. The BRABUS project vehicle was developed by the BRABUS ZERO EMISSION business division, in cooperation with the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety. The project vehicle has been developed to small-series-production maturity.

• The BRABUS development engineers have adapted two supplemental wheel hub motors from English manufacturer Protean ELECTRIC to the rear axle of the E-Class sedan

• These alternative drives, which in Eco mode each produce 50 kW of continuous power and 80 kW in Sport mode, are designed to fit in the BRABUS Monoblock Q 19-inch wheels

With a combined peak power output of 160 kW and a total peak torque of 1,600 Nm (1,180 lb-ft) the two electric motors supplement the existing 2.2-liter common-rail turbodiesel engine, which was equipped with a BRABUS ECO PowerXtra D3 (V) performance kit. This tuning kit consists of an auxiliary control unit that features engine mapping developed on state-of-the-art engine test benches for optimizing fuel economy and CO2 emissions.

The objective of this measure was less the power increase by 30 hp (29 bhp / 22 kW) to 200 hp (197 bhp / 147 kW) produced by the plug-and-play module. Much more important is the increase in peak torque from standard 400 to 450 Nm (295 to 332 lb-ft). It gives the vehicle even more pulling power, regardless of whether the vehicle is in hybrid or conventional operating mode, and results in better fuel economy and reduced CO2 emissions.

The two wheel hub motors turn the four-door car into the even more fuel efficient and ecofriendly BRABUS HYBRID. The various operating modes can be preselected from the cockpit.

During all-electric operation the car is powered by an 18.6-kWh lithium-ion battery pack housed in a custom-made well in the underbody. It gives the BRABUS HYBRID in all-electric Eco mode a maximum operating range of 120 kilometers (75 miles) without any CO2 emissions. Even in Sport mode the car has an all-electric range of 80 kilometers (50 miles), which easily meets the requirements of the majority of motorists who on average drive less than 60 kilometers (37 miles) a day.

During all-electric operation the batteries are charged by energy recuperation. While coasting or braking the system reaches a maximum recuperation power of 140 kW. For charging at home with ecofriendly eco electricity the use of the car charger from German energy provider RWE is recommended. It can recharge the battery pack with a current of 380 volts and a charging capacity of 50 kW in 30 minutes. On the road the batteries can be recharged with the on-board charger on any standard 220 V AC outlet or on a 380 V three-phase power supply.

In hybrid mode, the 200 hp (197 bhp) / 147 kW of the diesel engine and the maximum 160 kW of the electric drive in Sport mode work together in highly efficient fashion. Acceleration time for 0 – 100 km/h (62 mph) improves from standard 8.7 to 7.4 seconds.

Despite of the added weight of 255 kilograms (562 lbs.) compared to a stock E 220 CDI, the BRABUS HYBRID also shines in the area of pulling power thanks to its supplemental electric drive: the intermediate sprint from 60 to 120 km/h (37 to 74 mph) now only takes 5.6 seconds.

At the same time the combination with the electric motors eases the load on the combustion engine, significantly reducing fuel consumption and CO2 emissions further. Naturally drivers have the option to operate solely in diesel mode. In this case the batteries can also be recharged by the wheel hub motors which also function as alternators.

The work of the BRABUS development team was not limited to the integration of the two electric motors for all-electric or hybrid operation alone.

The higher vehicle weight and the altered weight distribution resulting from the installation of the wheel hub motors and the batteries in the rear necessitated the development of a new suspension. A height-adjustable comfortable sports suspension with variable damper rates was developed in cooperation with technology partner BILSTEIN.

The tires are supplied by technology partners Continental, Pirelli and YOKOHAMA. They are mounted front and back in size 245/35 ZR 19 on BRABUS Monoblock Q alloy wheels with five double spokes.

The brakes are a BRABUS custom development as well. Special brake discs gripped by two calipers per wheel are attached to the rear of the wheel hub motors on the rear axle. All standard driver assist systems such as ABS and Brake Assist are retained.

The BRABUS front fascia, manufactured like all body components in OEM quality from high-grade Pur-R-Rim plastics, is designed to replace the production bumper in its entirety. Its sophisticated shape reduces lift on the front axle and also lends the sedan an even more striking nose. An innovative lighting concept with economical LED daytime running lights furthermore optimizes active safety.

BRABUS front aluminum sport fenders emphasize the sporty appearance of the concept car. BRABUS side skirts give the sedan a longer, sleeker appearance. Integrated LED entrance lights ensure safe entering and exiting of the vehicle in the dark. A blue-backlit BRABUS logo is integrated into each sill and activated together with the entrance lights.

BRABUS aluminum pedals and footrest add sporty highlights to the interior. A newly developed instrument cluster provides information about the state of charge of the battery pack. A control panel in the cockpit gives drivers the option to select all-electric mode, hybrid operation or diesel engine only.

Solar Cells, carbon-fiber-reinforced epoxy resin, an infrared-reflective heat shield – it sounds a little like an equipment list for NASA. But in fact, these components are all found on the new smart forvision, set to be presented this month at the 2011 International Motor Show in Frankfurt. The joint vision between smart and BASF seeks to show the forward-thinking design that is being put into Daimler’s vehicles above and beyond the drive system.

“With the forvision smart is doing justice to its role as Daimler’s think tank for urban mobility. We are presenting numerous world premieres that make uncompromising electric mobility possible. With the clear objective of greatly increasing the zero-emission range we concerned ourselves with all factors that influence this on the vehicle. This resulted in completely new concepts and materials in the areas of insulation, reflection, lightweight design and energy management. In addition to transparent organic solar cells, transparent and energy-saving light-emitting diodes and infrared-reflective films and coatings, high-performance foams are used for insulation against cold and heat. smart is also setting new standards of lightweight design with the use of the first all-plastic wheels”, says Dr. Annette Winkler, Head of smart. “In conjunction with smart’s revolutionary DNA, we have designed a vehicle that is so unique that we can’t wait to take it out of the research laboratory and onto the roads!”

“Cars of the future need materials and technologies which reduce energy consumption whilst also increasing the range and level of comfort. Our innovations make a decisive contribution to this”, says Dr. Christian Fischer, Head of BASF Polymer Research. “We are proud to have developed a holistic concept for sustainable urban mobility in cooperation with smart. Together we are presenting a pioneering vehicle which is without parallel.

Thanks to the combination of smart’s automotive expertise and BASF’s material and system competence a vehicle has been created which showcases technologies for sustainable and holistic electric mobility of the future. The researchers and designers intentionally realised a mixture of visionary materials and technologies in the concept vehicle – some of these are still at a laboratory stage, while others have a realistic chance of entering series production.

Energy efficiency: light and energy from above

The hexagonal transparent areas on the roof of the smart forvision are an eye-catching feature – as the first light-transmitting roof that also generates energy. Transparent solar cells covering the entire roof surface are the technology used here. They are based on organic dyes embedded in a sandwich roof. The transparent dyes of the solar cells are light-activated. Even in diffused light and poor light conditions they generate enough energy to power the multimedia components and the three fans that assist with climate management in the vehicle interior. If the vehicle is standing in the sun the ventilation is permanently operated with the help of these solar cells, keeping the car cool. This new photovoltaic technology opens up further efficiency potential and the energy generated can be used for further applications in the car.

There is an additional new feature under the solar cells: transparent OLEDs (organic light-emitting diodes) illuminate the vehicle interior when the door is opened or a button pressed. When switched off they allow for a clear view outside. This results in a glass roof effect during the daytime, whilst the areas are pleasantly illuminated without any dazzle at night. Thanks to a free choice of colors the new OLEDs do not only offer more design freedom, they also consume less than half as much energy as conventional energy-saving lamps.

Lightweight design: different, better, stylish

In the smart forvision a world first leads to a considerable weight reduction and a unique design: the first all-plastic wheel suitable for high-volume production. In its current development status, the wheel developed by BASF from a new high-performance material results in a considerable weight saving of three kilograms per wheel. Unlike conventional polyamide composite materials this new plastic has long reinforcing fibres which improve its mechanical properties. The result: excellent thermal and chemical stability, dynamic strength, toughness and good continuous operating characteristics. First intensive product tests at smart show the performance capability of the all-plastic wheel and confirm the potential for possible use in production vehicles.

In addition to the tridion passenger cell, further components such as the doors are made of carbon-fiber-reinforced epoxy resin – a high-performance composite material. The use of such materials enables a weight saving of more than 50 percent to be achieved compared with steel, or 30 percent compared with aluminium. Thanks to short hardening times the resin systems from BASF are also suitable for producing larger volumes.

Heating: close to the body and efficient

The multifunctional, comfortable and lightweight seats in the smart forvision offer a unique combination of efficient temperature management and an energy-saving lightweight design. Here, several innovative products are combined with one another for the first time. A new, lightweight, self-supporting plastic seat shell forms the basis.

Numerous studies have shown that the body only absorbs heat efficiently through certain contact points. This is why “e-textiles” – thin fabrics with custom-tailored conductive coatings – replace conventional seat heating in the smart forvision. With direct heating close to the body in the middle and lower back area of the seats they provide for a pleasant feeling of warmth. The energy, space and weight-saving e-textile technology is also found in the armrests of the doors and ensures that body contact points sensitive to the cold are also warmed in this area.

The innovations continue with the seat foam, which provides for both comfort and weight savings. The material from BASF is around 10 to 20 percent lighter than other materials and enables different degrees of hardness to be realised in different areas of the upholstery in a single work operation – resulting in clear ergonomic advantages.

Superabsorbent containing fleece fabric integrated in the seat greatly enhances seating comfort through its passive climate control. Compared with conventional climate-controlled seats the lightweight seat in the smart forvision does not have the complexity and energy requirement of mechanical ventilation.

Temperature management: heat stays outside

As a large amount of energy is needed to air condition and heat a vehicle, temperature management was a key focus area for the smart and BASF researchers. A whole package of measures has been implemented in the smart forvision to ensure more efficient air conditioning of the vehicle.

At the same time they make energy-intensive heating of the whole interior superfluous.

A heat shield that has not been previously used for automotive applications consists of a new kind of infrared-reflective film from BASF applied in the windscreen and side windows, protecting the car interior from heating up. Integrated between the panes of the safety glass the metal-free film ensures that the infrared rays are effectively reflected. Thanks to its high transparency in the visible range it can also be applied to tinted windows and guarantees an unprecedented level of reflection of sunlight and heat. Unlike metallized films, which are already used in some vehicles, the new film reflects only the infrared rays of the sun. Radio waves needed to use GPS, Bluetooth, mobile phones or for toll collection pass through the glass unhindered.

The high-performance foams from BASF fitted in the bodypanels also provide for a pleasant climate inside the car. They keep the vehicle pleasantly cool in summer and also insulate it against the cold in winter. Thanks to their high efficiency even in a small width, they can be fitted everywhere in the vehicle. With this innovative insulation system in the smart forvision, the two companies are breaking new ground in the automotive sector.

Cool coatings – cool interior

The infrared-reflective and extremely scratch-resistant coating system covers two important aspects at once. Firstly, it supports the extensive temperature management system and, secondly, the brilliant and high-quality look of the coating underlines the unique design of the smart forvision. The concept vehicle features a white special-effect coating with glass flakes that create a gleaming metallic look. An important side effect: the colour white reflects heat rays from sun and light particularly well. But even surfaces coated with dark colours stay much cooler thanks to special colour pigments from BASF. They ensure that heat radiation is reflected rather than absorbed. This leads to a temperature reduction of up to 20 degrees Celsius on the paint surface and of up to approximately four degrees in the vehicle interior.

Futuristic design trendsetter

Painted in pearl white and accentuated by the tridion safety cell coated with a copper-coloured liquid metal paint, there is a deliberate connection between the basic structure of the smart forvision and the design of the smart fortwo. Trendy yet high quality – the aluminium flakes in the liquid metal paintwork create a reflecting surface on the safety cell, changing between light and dark depending on the viewer’s perspective. Both the panels and the cell of the smart forvision are additionally painted with an extremely scratch-resistant clear coat.

The faceted side doors with integrated door openers are a real eye-catcher. Here, plastic is presented in a new, expressive and three-dimensional form; a reinterpretation that is only possible at smart thanks to the consistent use of plastic. The precise facets give the area stability and enable a smaller material thickness to be used. Optimal use is made of the possibilities offered by plastic as a material. In contrast, the front and rear have a softer design with smooth transitions from the doors. Just as the integrated door handle does not need an additional component, the familiar smart air inlet is represented by small hexagons located right on the outer skin.

The jet-like rear lights are reminiscent of small aircraft turbines and give the rear a futuristic and sporty look. Inside the lights, small propellers convey the air from the inside to the outside. In addition to all the light functions needed, transparent stacks in the form of rings around the lights also show the charge status of the battery during charging.

The headlamps are emphasised by a ring comprising the daytime driving lights and indicator functions. The lights add to the likeable expression of the smart forvision.

Doors open to the future

With a mix of polygonal surfaces and organic shapes the interior of the smart forvision builds a bridge to the architectural design handwriting of the exterior. This also applies to the colour concept: a cool white dominates in the interior as well, accentuated by the inner part of the instrument panel in liquid copper. Hexagons in the form of white rubber nubs on a white floor are a reference to the design idiom of the overall vehicle, as is the tone-in-tone design of the seat upholstery.

The faceted surface of the side doors is also found on their inside. The polygonal surfaces with integrated armrests and stowage compartments curve into the interior. They are painted in the body color and feature coloured LEDs. These guide the driver with a light animation running from the outside to the inside when the door is opened and closed. After closing the door the animation changes to unobtrusive ambient lighting.

The elliptical user interface with a copper coloured frame – matching the lightweight tridion – is semi-transparent when switched off. When the vehicle is switched on all cockpit information is then projected onto the transparent surface. The driver uses a touchscreen to switch between operating menus.

The white steering wheel that is reminiscent of an aircraft yoke additionally gives the cockpit a futuristic look. As well as function buttons the LED display for the battery charge status is found here.

Forward-looking technologies

The smart forvision not only shows that electric mobility can make emission-free driving possible. At the same time, it paves the way for new technologies in the automotive sector. Many of these innovations are based on nano technology, the key to the development of sustainable solutions. Nano materials serve as drivers of innovation in the automotive industry, as they do in the fields of construction, energy, healthcare and electronics.

The total of all technologies integrated in the concept vehicle make a perceptible contribution to increasing the range.

This is always at the centre of discussions relating to battery-electric driven vehicles. With maximum energy efficiency, intelligent temperature management and consistent lightweight construction it is possible to increase the range by up to 20 percent. An additional bonus for electric mobility of the future.

The third generation smart fortwo electric drive offering zero-emissions will be available beginning in the spring of 2012. Following on the heels of the second generation’s success, the next generation smart will give electric mobility to all those interested in more than 30 markets worldwide. In the development of the new generation smart benefited from extensive experience and customer feedback gathered worldwide over the past years. Driven by a battery supplied by Deutsche Accumotive for the first time the 55 kW electric motor passes the 74mph mark. From 0 to 62 mph in less than 13 seconds – even driving on urban motorways becomes enjoyable. The 17.6 kWh battery enables the smart fortwo electric drive to travel around 87 miles in city traffic without producing any local emissions.

“The smart fortwo has exceeded itself. It has always been a pioneer of urban mobility and with the new electric drive it is once again setting standards with even more driving fun and environmental compatibility,” says Dr. Annette Winkler, Head of smart. “With the new generation the frequently cited “electric era” has finally arrived.” For the further development of the smart fortwo electric drive the company was able to bring in extensive experience and customer feedback from various electric mobility projects. For example, this is reflected in clearly improved performance data. Driven for the first time by energy from a battery supplied by Deutsche Accumotive the 55 kW electric motor effortlessly passes the 120 km/h mark. The smart developers were also able to realise the more powerful acceleration requested by customers. From 0 to 100 km/h in less than 13 seconds – even filtering into traffic on urban motorways is a pleasure. The 17.6 kWh battery enables the lively city car to travel considerably more than 140 kilometres without producing any local emissions.

Ever since 1998 the smart has been revolutionising urban mobility like no vehicle before it. Compact, agile, environmentally friendly and stylish – it has evolved from a practical small car to a lifestyle product and has long become a familiar sight on the roads of cities around the world.

With the start of the first electrically driven test fleet in 2007 in London smart also took on a pioneering role in the area of electric mobility when 100 smart fortwo electric drives took to the roads of the British capital – with great success. Today the vehicle is a trendsetter and a synonym for forward-looking battery-electric-driven urban mobility of the future.

One of the largest electric fleets worldwide

With the introduction of the second generation in 2009 the smart fortwo electric drive was ready to take to the roads. The electrically driven avant-gardiste from Stuttgart was introduced in 18 markets. The objective of the second generation was to gather as much experience as possible about how customers use and charge electric vehicles. The huge demand exceeded all expectations. Instead of the planned 1000 vehicles more than 2000 smart fortwo electric drives are being produced in Hambach. This means that smart has one of the largest fleets of electrically driven vehicles on the roads worldwide and a trove of customer experience and wishes that have been input in the third generation smart fortwo electric drive.

A higher top speed and better acceleration at speeds above 37 mph were right at the top of the customers’ list of priorities.

Contrary to prevailing opinion the range wasn’t the crucial point from the perspective of the test customers. The vast majority of users confirmed the results of surveys which say that people drive approximately 30 to 40 kilometres per day on average in urban areas and they expressed great satisfaction with the range of their smart.

Even better in the third generation

With total production amounting to a five-figure number, from the spring of 2012 the further developed smart fortwo electric drive will start winning wide-ranging buyers in more than 30 countries for an innovative and forward-looking drive concept.

The third generation smart fortwo electric drive features a 55 kW magneto-electric motor – the first product from the EM-motive joint venture founded together with Bosch – which ensures that it is as agile and lively as ever. With torque of 130 Newton metres it accelerates powerfully and immediately from 0 to 60 km/h in 5 seconds and thanks to better acceleration in the higher speed range it can sprint from 0 to 100 km/h in less than 13 seconds as it has much more tractive power than its predecessor. This makes for speedy driving and overtaking. The battery-electric two-seater smart fortwo now also has a higher top speed of more than 120 km/h, putting it on a par with the combustion-engined smart.

A battery supplied by Deutsche ACCUmotive is fitted in the new smart fortwo electric drive for the first time. With capacity of 17.6 kWh the lithium-ion battery from the joint venture with Evonik Industries provides for well over 140 kilometres of pollutant-free driving fun. In addition to the higher battery capacity clear improvements have been made to the efficiency of the drive system, resulting in a greater range. When completely empty it takes a maximum of eight hours to fully charge the battery at a household socket or charging station on the electricity systems of most countries i.e. overnight.

Quick charging in just one hour

For the greater freedom of quick charging it is possible to optionally equip the vehicle with a quick-charging function. The 22 kW on-board charger enables a completely empty battery to be fully charged in less than an hour. A power cable is needed for this which is used to connect the vehicle to a public quick-charging station or a wallbox at home or work.

A comparison of the two smart fortwo electric drive generations

A fresh green and even more colours

With a larger radiator grille featuring the electric drive logo, stylish LED daytime driving lights below the headlamps, wider door sills and several modifications to the rear the new model is much more dynamic than its predecessor.

The new smart fortwo electric drive comes in all smart colours and colour combinations that are also available for the diesel and petrol models.

The new colour fresh green is a particularly visible manifestation of electric driving fun. In addition to crystal white bodypanels the electric drive design package comprises white alloy rims, a green tridion cell, green mirror caps and numerous green accents in the interior which form an attractive contrast to the black seats.

Perfectly equipped

As to be expected the new smart fortwo electric drive features extensive equipment. A highlight is the fully automatic air conditioning with pollen filter and pre-air conditioning. As with the second generation the vehicle can be pre-cooled or pre-heated as required for a programmed departure time when it is connected to the power network. A new feature is the possibility to start the pre-air conditioning via the internet or a smartphone at any time. The standard equipment furthermore includes electric windows and electrically adjustable door mirrors, a leather steering wheel, leather gear knob, the entry line radio, power steering, 9-spoke alloy wheels and a luggage compartment cover. As with the predecessor model in addition to the standard solid roof a glass roof and a cabrio version are available. The trip computer – also a standard feature in the electric smart – shows journey information including the remaining range. And like the predecessor model the two round instruments show the charge status of the battery and the energy used and recuperated. In addition, the smart fortwo electric drive can be equipped with a navigation system and a 3-spoke leather steering wheel.

All the destinations that can be reached with the current battery charge are displayed. The public charging stations within reach can also be seen at a glance. If a desired destination is further away than the available range the Vehicle Homepage can be used to quickly check the additional battery charge needed. Among other things the depiction of the range considers the topography and the route profile. The intuitive graphic depiction that can be combined with 3D views and satellite images is an attractive feature. Furthermore, the vehicle itself can also become active. Information on the charge status and range can be sent by email or Twitter messages for example. The driver is notified as soon as the desired range can be reached with the current charge.

Intelligent charging

The smart fortwo electric drive can be connected to the internet at home via a standard powerline adapter (Homeplug AV) for SmartCharging. After entering the planned departure time in the vehicle or the web portal the vehicle will be fully charged in a battery-saving and economical way, and pre-air conditioned if required so that it is ready to start. The pre-air conditioning can also be conveniently activated online shortly before setting off.

Daimler and The Linde Group, a technology company, announced Wednesday that they are moving forward with the development of an infrastructure for hydrogen-powered fuel-cell vehicles. The two companies plan to construct an additional 20 hydrogen filling stations in Germany over the next three years, thereby ensuring a supply of hydrogen produced purely from renewable resources for the steadily increasing number of fuel-cell vehicles on the roads. The initiative links in with the existing H2 Mobility and Clean Energy Partnership infrastructure projects, which are being subsidised by the National Innovation Programme for hydrogen and fuel-cell technology (NIP). This places Germany at the international forefront of hydrogen infrastructure development.

The initiative that Linde and Daimler are embarking upon involves investment running into the tens of millions, and is set to more than triple the number of public hydrogen refuelling points in Germany. The new stations will be located in the current hydrogen centres of Stuttgart, Berlin and Hamburg as well as along two new continuous north-south and east-west axes. The aim is to use existing sites belonging to different petroleum companies that are strategically located in the traffic network. This will make it possible to drive anywhere in Germany with a fuel-cell-powered vehicle for the first time. One of the focal points for the infrastructure’s extension will be in Baden-Württemberg, where, 125 years after the invention of the motor car, the stage is being set for its reinvention.

“Together with the fuel cell, hydrogen is set to be of fundamental importance to the expansion of electromobility,” explained Prof. Dr. Wolfgang Reitzle, Chief Executive Officer of Linde AG. “We are delighted to be able to play such an instrumental role in shaping this development together with Daimler. We see ourselves as providing an impetus for existing initiatives, such as H2 Mobility and the Clean Energy Partnership (CEP), and wish to support the commercialisation of hydrogen vehicles as best we can. By systematically developing hydrogen technology, Germany can assume a pioneering role in this field and establish itself as the industry leader as we move towards emission-free mobility.”

“The fuel cell represents a decisive step forward for electromobility, as it enables zero-emission driving with high ranges and short refuelling times – and not just for passenger cars, but for commercial vehicles too. In partnership with Linde, we are now taking the next step by getting things going on the infrastructure side. 20 new hydrogen filling stations will give the market a major stimulus,” remarked Dr. Dieter Zetsche, Chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz Cars at the finish of the Mercedes-Benz F-CELL World Drive in Stuttgart. Having started off from Stuttgart at the end of January, the first circumnavigation of the globe in fuel-cell vehicles took in four continents and 14 countries. Each of the vehicles involved covered over 30,000 kilometres. Linde accompanied the F-CELL World Drive as the exclusive hydrogen partner, providing the zero-emission vehicles with a mobile supply of hydrogen for the duration of the tour.

Construction and commissioning of the new filling stations will already start in 2012. Other partners from the petroleum, power supply or automotive industries, for instance, are welcome to become involved in the joint initiative that has been set up by Daimler and Linde.

Background: the infrastructure of hydrogen filling stations in Germany

The successful introduction of fuel-cell vehicles depends on the development of a public hydrogen supply infrastructure. The first centres have already sprung up in large metropolitan areas, such as Berlin and Hamburg. There are nearly 30 hydrogen refuelling points in Germany at the current time, seven of which are integrated into a public filling station facility. This means that Germany clearly leads the way in Europe. To begin with, just five to ten filling stations are sufficient for conveniently servicing the requirements of a large city. Joining up these urban centres – for example Berlin with Hamburg, Stuttgart with Munich – by means of corridors along the arterial roads between them is a major step forward towards the establishment of a nationwide public H2 infrastructure.

After 70 days of driving and more than 18,000 miles, the B-Class F-Cell’s have circled the globe and returned home to Stuttgart becoming the first round-the-world drive with fuel-cell vehicles.  The three Mercedes-Benz B-Class F-CELL vehicles with zero local emissions drivelines crossed the finish line on June 1, 2011 in front of the Mercedes-Benz Museum in Stuttgart. The hydrogen-powered B-Classes and their support vehicles set off from Stuttgart at the end of January on the occasion of the official 125th birthday of the automobile, and on their way have crossed through 14 countries on four continents.

“With the F-CELL World Drive we have shown, that the time for electric vehicles with fuel cell has come. Now the development of the infrastructure has to pick up speed,” said Dr. Dieter Zetsche, Chairman of the Board of Management and Head of Mercedes-Benz Cars. “For only an adequate number of hydrogen fueling stations enables car drivers to benefit from the advantages of this technology: high range, short refueling times, zero emissions.

Hydrogen infrastructure challenge

Within the scope of the F-CELL World Drive, the Mercedes-Benz B-Class F-CELL was functioning as an ambassador for a new, zero-emissions auto-mobility of the future. At the same time, Mercedes-Benz was lobbying extensively for the establishment of a comprehensive network of hydrogen fueling stations – a crucial factor for the market success of this technology. So far, there are only approximately 200 fuel stations worldwide at which fuel cell vehicles can be refueled. According to expert calculations, a network of around 1,000 fixed fuel stations would be sufficient for basic nationwide coverage in Germany. A central aim of Mercedes-Benz is to see to it that, in future, drivers all over the world will be able to refuel with hydrogen – just as they do today with gasoline and diesel fuel.

The exclusive partner for hydrogen supply on the F-CELL World Drive was the Linde Group. Thanks to its hydrogen expertise and global presence, it was able to guarantee fuel supply throughout the entire world trip. A jointly developed mobile refueling unit based on a Mercedes-Benz Sprinter accompanied the tour – the only way to ensure fuel supply even on the most remote stretches.

Proof of the everyday usability of fuel-cell drive

During the F-CELL World Drive, Mercedes-Benz was able to provide an impressive demonstration of the qualities of its fuel cell vehicles in terms of performance and robustness. The World Drive vehicles drove not only in downtown areas, on country roads and lengthy stretches of highway, but also proved their capabilities driving on unfinished surfaces, for example on stages in Australia and China.

Even a no-fault accident in Kazakhstan was unable to stop the B-Class F-CELL. On the route from Almaty to Balkhash, the number-three B-Class F-CELL was rammed on its rear left fender. The rear axle and bumper of the fuel-cell car both sustained damage. However, the fuel cell vehicle was repaired in a nearby workshop and continued its way around the world. Only a small dent in the bodywork bears testament to this single incident.

Round the world with hydrogen – the tour in figures

After 70 days of driving, participants in the F-CELL World Drive collected an abundance of travel notes documenting the multi-faceted aspects of the tour and, at the same time, underscoring the everyday usability of the fuel cell technology on board the B-Class F-CELL. The record distance of 648 kilometers, split between two stretches of more than 300 kilometers each, was covered on the drive from Almaty to Balkhash in Kazakhstan. Another likely record is the number of inhabitants in the places visited by the tour, ranging from no more than twenty in Balladonia, Australia, to an impressive 19 million in Shanghai, China. Due to the still insufficient hydrogen infrastructure, the mobile unit, which has been developed in cooperation with the Linde AG, was used around 130 times to refuel the B-Classes. Along the route, the B-Class F-CELL vehicles were also refueled in just a few minutes at two hydrogen fueling stations.

Mercedes-Benz long-distance drives – in the tracks of Bertha Benz

With the now historic F-CELL World Drive, the first round-the-world drive with fuel cell vehicles, Mercedes-Benz is adding to a long history of legendary long-distance drives. Examples include the first crossing of Africa in a car in 1909 and the longest diesel marathon – the “E-Class Experience” – run in 2006 over 14,000 kilometers from Paris to Beijing.

As far as its objective was concerned, the F-CELL World Drive has a direct connection to the world’s very first long-distance drive – the pioneering endeavor of Bertha Benz, who, in 1888, completed the first cross-country drive with the Benz Patent-Motorwagen from Mannheim to Pforzheim. She faced in principle the same challenge as her successors with the B-Class F-CELL – she, too, could not exactly roll into the next fuel station and top up.

In the early days of the automobile, drivers had to buy their fuel from the pharmacy, which is why Bertha Benz stopped at the town pharmacy in Wiesloch. That was the only place she could acquire the light gasoline “ligroin” – which was actually intended for domestic use as a stain remover, but also worked as fuel. First gradually, then with increasing speed, the fuel station network expanded into the worldwide infrastructure we know today. That was a defining factor in the triumphant procession of the combustion-engine-powered automobile invented in 1886 by Daimler and Benz. With new drive systems the motto is: alternative drives need alternative infrastructures. In the case of the B-Class F-CELL, this means hydrogen fueling stations. It is for this reason that Mercedes-Benz, as the inventor of the automobile, together with partners from commerce and politics, is lobbying heavily for the establishment of a comprehensive infrastructure – both for electric cars with fuel cells and for those with battery-electric drive.

There are only a few hours left for the three neon green Mercedes-Benz B-Class F-Cell’s that took a journey around the world. The F-CELL World Tour is scheduled to arrive in Stuttgart on June 1st to what we can only imagine will be one hell of a welcome home party. If you’re interested in celebrating their return, head to the Mercedes-Benz Museum in Stuttgart at 3 pm June 1st.

If you are unfamiliar with the F-CELL World Drive and the B-Class F-Cell powered electric cars, they are an example of how developing a technology can also be in harmony with nature. The goal for future mobility is to eliminate Co2 emissions and the F-Cell showcases a technology that has the potential to make this possible.

Recap of F-CELL World Drive legs 24-27:

After a 9000-kilometre journey through China and Kazakhstan and some 25,000 locally emissions-free kilometres covered, our three fuel-cell vehicles crossed the final continental boundary of the tour on 15 May 2011: the 107th day of the F-CELL World Drive saw the tour head from Chelyabinsk to Ufa in Russia, and from there back to Europe, marking the successful crossing of the fourth continent of the journey, Asia. Just five countries remain for participants over the final 5000-kilometre leg of the tour, which is scheduled to finally return to Stuttgart on 1 June after 125 days.

Our three B-Class F-CELL vehicles are expected to cover more than 3000 kilometres on their journey through Russia before crossing into Finland on 23 May, and then on to the home straight via Scandinavia. The first stage on Russian soil, which leads from Chelyabinsk to the capital Moscow over four days, brings the tour back to Europe.

Mercedes-Benz F-CELL World Drive in Europe – Leg 24: From Moscow to St. Petersburg

From the Russian capital Moscow, the F-CELL World Drive starts on its 24th leg on May 20. During three days, the vehicles travel 800 kilometers to St. Petersburg. One day before, local media took the opportunity to test drive the locally emission-free B-Class F-CELL in Moscow.

Mercedes-Benz F-CELL World Drive in Europe – Leg 25: From St. Petersburg to Helsinki

On May 23, the F-CELL World Drive embarks on one of the shortest legs of the world tour: the one-day trip leads the participants from St. Petersburg in Russia into the finish capital Helsinki, thereby covering 450 kilometers. The journey then will continue from Helsinki to Stockholm via ferry.

Mercedes-Benz F-CELL World Drive in Europe – Leg 26: From Stockholm to Oslo

From Stockholm in Sweden, the tour embarks on a 550 kilometers-journey to the neighbouring country Norway, to Oslo. The interest in fuel cell technology there is great: After Germany and the USA, Norway will be the third market where the B-Class F-CELL will be introduced. Also, on May 27, representatives of the local media have the opportunity to learn about fuel cell technology in Oslo.

Mercedes-Benz F-CELL World Drive in Europe – Leg 27: From Oslo to Hamburg

On May 28 the F-CELL World Drive embarks on a two-day trip, leading it towards its destination Germany, where the tour departed from in January. From Oslo in Norway via Malmö in Sweden the route leads to Hamburg. The vehicles thereby cover a distance of 1.200 Kilometer in four countries. Before the beginning of this leg, media representatives in Oslo took the chance of a press event to learn about the emission-free fuel cell technology, which will soon be available in Norway.

Update: 06/01/2011

On May 30, the fuel cell vehicles will embark on the last leg of the F-CELL World Drive, leading them from Hamburg via Berlin and Nuremberg to the Mercedes-Benz Headquarters in Stuttgart. About XXX guests will then welcome the convoy after its 125-day trip in the course of a festivity, taking place in the Mercedes-Benz Museum. Furthermore, the Stuttgart-based automotive manufacturer hosts events in Hamburg, Berlin and Nuremberg in order to draw attention to the potential of fuel cell technology and the need for a comprehensive hydrogen infrastructure.

AMP Electric Vehicles, a company offering emission-free electrification of OEM vehicles, AMP handed over the keys of an electric Mercedes-Benz ML 350 to the company’s newest and biggest client, Gisli Gislason, the chairman and chief executive of Northern Lights Energy, a utility in Iceland.

This is the initial delivery committed in AMP’s long term supply agreement with the Icelandic company signed on April, 14, 2011. The Mercedes SUV was just the first vehicle produced in accordance with the five-year contract between the two companies, during which Amp expects to ship 1,000 E.V.’s to the island nation.

In the past, Amp has converted only General Motors passenger cars, primarily the Chevrolet Equinox crossover.. The Mercedes-Benz ML’s proportions are similar to those of the Equinox, which helped in the conversion, particularly to house the company’s 900-pound battery unit.

“We retained a split battery pack to keep the weight balance about equal to the original manufacturer’s specification,” said Steve Burns, president and co-founder of Amp, in a telephone interview. “We can even lower the center of gravity a bit to give it better handling.”

The ML’s global distribution was also a consideration for Amp. “It’s a world car, so it’s already passed Euro and U.S. crash-safety tests,” he said. “That’s the benefit of our approach; we didn’t have to worry about developing a defroster or a windshield wiper.”

Amp is not committing exclusively to the ML as its future platform, nor is it trying to lock up a contract with one battery supplier (Mr. Burns declined to name the current supplier of its batteries). This is an advantage of the company’s business model, Mr. Burns said. “We have a five-year contract, so you can imagine what batteries will do during that time,” he said. “We try to be battery agnostic.”

Mr. Burns estimates that the ML should travel 100 miles on a charge in pure highway driving, which compares favorably to the estimated range of the Nissan Leaf, despite the ML weighing nearly 2,000 pounds more than the purely electric Nissan.

Though primarily an electricity provider, Northern Lights will function as a distribution channel for the Amp vehicles. Mr. Gislason is working to secure orders from companies, municipalities and individual buyers in Iceland, who, according to Mr. Gislason, should be easy quarry.

“Gasoline is about $8 a gallon right now, and Iceland has low import taxes on E.V.’s,” he said in a telephone interview. “A Mercedes S.U.V. would be basically the same price to import, plus you’d have to purchase gas. For us, it’s a no brainer.”

Iceland also generates much of its electricity through geothermal and hydroelectric sources, which increases the cost benefit of E.V. operation, he said.

The utility’s agreement with Amp is not exclusive, so Northern Lights could conceivably become partners with other E.V. manufacturers. However, Mr. Gislason does not expect that to occur soon. “Amp can deliver us cars. Today, they gave us a real car. We’re not being told by a big manufacturer, ‘Oh, there’s a delay.’ We’re getting them right now.”

Over the weekend we brought you the first look at the smart forspeed electirc roadster along with a wealth of photos, and today, smart has officially launched the model.  Combining contemporary urban mobility with the fun factor typical of smart, the two-seater smart forspeed roadster has no roof or side windows and it features a low wind deflector instead of a windscreen in the style of a classic propeller aircraft. The result is an incomparable fresh air driving experience. The responsive electric drive that has been further developed and features a boost function also guarantees driving pleasure. A look forward at the next generation is particularly exciting as the era of electric mobility has already started at smart.

No roof, minimal windows and a responsive and zero-emission electric drive at the rear: the smart forspeed combines responsibility and emotional appeal in a new and pleasurable way. Dr. Annette Winkler, Head of smart says “The smart forspeed is a completely new take on how much fun it is to drive electric: it boasts a superb design with a powerful drive system and, needless to say, locally emission-free. And if you put the smart forspeed next to our ebike, escooter and smart fortwo electric drive you’ll see that smart has realised all kinds of variations of electric driving – demonstrating that smart is not just a practical city car, but a great idea.” The smart forspeed boasts an extremely innovative and self-assured design. Prof. Dr. h. c. Gorden Wagener, Head of Design says “The cult brand smart has always taken an unconventional approach with bold design. The forspeed now carries purist sportiness to extremes and in terms of form it is also a pioneer for a new paradigm of mobility.”

Powerful and environmentally friendly electric drive with an extra boost

smart is a pioneer in modern electric mobility. The second generation smart fortwo electric drive has been delivered to customers since the end of 2009. It is been proving its suitability for everyday use in 18 countries including Germany, Italy, Spain, England, France, Switzerland, the USA, Canada and further countries in Asia. Due to the high demand production figures have been increased to 1500 vehicles. Thanks to this experience smart has already collected extensive customer feedback that has been integrated in the development of the smart forspeed’s electric drive. With its improved performance and charge management the concept vehicle offers a look at the performance potential of future generations of the electric smart.

For example, the smart forspeed accelerates from 0 to 60 km/h in just 5.5 seconds and reaches a top speed of 120 km/h. A 30 kW magneto-electric motor is installed at the rear of the smart forspeed and the vehicle concept provides an immediate powerful response from stationary. Pressing a button in the centre console activates a boost function which provides an extra 5 kW of power for a short time and is ideal for overtaking manoeuvres on urban highways, for example. The smart forspeed is powered by a lithium-ion battery that delivers 16.5 kWh of electrical energy. It is simple to charge at any conventional 220 Volt socket. The charging device is located in the third brake light behind the smart logo and features a simple push/push opening mechanism. A fully charged battery is sufficient for 135 kilometres of driving fun (NEDC). Quick charging from 0 to 80 percent takes just 45 minutes.

The forspeed developers have integrated a further clever way of charging in the wind deflector: photovoltaic cells feed solar power to the on-board electrical system. As with the smart escooter this lengthens the battery life of the smartphone, for example.

Unconventional exterior

With its high-gloss white metallic paintwork the smart forspeed also builds a bridge to the two-wheel escooter and ebike studies that were presented at the Paris Motor Show.

The front and rear lamps have a very striking design. The outer rings are illuminated by a large number of rod-shaped LEDs whilst the centre of the lamps is white. The indicators seem to push outwards like arrows – like drops on the cockpit window of an aeroplane as it takes off. In the front and rear bumpers numerous holes with a honeycomb structure serve as air inlets and create an interesting progressive pattern. At the same time this pattern gives the forspeed a particularly wide appearance and a powerful road stance. The smart forspeed is fitted with front tyres in size 205/35 R 18 to match its dynamic look. On the driven rear axle the tyres measure 235/30 R 18 for full grip.

Purist and sporty interior

The exterior and interior of the smart forspeed are designed as a formal unit. This is manifested in numerous details: the tridion safety cell flows from the outside behind the roll-over bars towards the front to the cockpit and forms the centre tunnel as a load-bearing part. The outer and inner door sections connect seamlessly to form a single component, just like the floor and side walls. The leather seats also have a one-shell design and are a modern interpretation of purist sportiness.

The air inlet in the wind deflector ends in the central outlet in the centre console and can provide even more fresh air for the interior when needed.

The high-gloss white of the exterior paintwork also dominates in the interior. It is accentuated by green elements such as the sporty four-point seat belts for driver and passenger or the large horizontal shelf under the cockpit that provides stowage space. All the control elements that the driver uses particularly frequently, such as the gear lever, door openers or steering wheel come in natural brown leather. By contrast, load-bearing structural components such as the tridion safety cell or the curved trims on the instrument hoods are in matt platinum silver. Functional elements such as the steering wheel buttons and the shift lever with gate are painted in silver shadow.

The open two-seater has been deliberately designed without an outer door handle – an interior grip is all that is needed to open the door. The control for the electric parking brake is particularly convenient to operate and also has a simple and functional design: the switch on the centre tunnel is reminiscent of the lever used to pull in the landing gear of aircraft.

There is a block with ten LEDs in the middle of the instrument panel. When the forspeed is started the LEDs shine through the translucent paint and show the battery charge status of the electric smart. When switched off noting is seen of the charge indicator except its outline.

Weatherproof thanks to tonneau cover and coating

The whole interior of the smart forspeed can be protected against rain and sun when necessary with a tonneau cover. It is an easy matter to stretch it over the interior and fasten it to the body with the straps. It can be divided in the middle with the help of a zip to free the driver’s seat only, for example.

But even without weather protection a downpour will not lead to any serious problems. Water drainage channels in the vehicle floor ensure that water is channelled outside. The seat surfaces also have water drainage channels and all interior equipment has a waterproof coating for fun behind the wheel regardless of the weather.

Smartphone as a communication centre

The purist sportiness of the interior is also reminiscent of classic aircraft construction: the driver and co-pilot sit in front of two separate round turbine-like instrument clusters. Whilst the driver has the speedometer firmly in his field of vision, the passenger is responsible for communication and navigation: this area of the cockpit features a smartphone. It can be swivelled by up to 90 degrees in its holder and towards the driver so that the driver can also take a look at the display of the navigation system.

As in the production models from smart, the smart drive app for the iPhone® has all the important features needed whilst driving: phone calls via hands-free system, navigation with a special smart touch and a Car Finder that guides the driver back to the parked car.

Intelligent lightweight design, optimised aerodynamics and state-of-the-art LED technology

With its body made of glass fibre-reinforced plastic the smart forspeed is a real lightweight. The low power-to-weight ratio is conducive to driving pleasure. Moreover, the dynamic two-seater boasts excellent aerodynamics: round, taut forms, a deliberate lack of joints (for example on the single-piece front module), smooth, handleless surfaces on the doors and rear lid and the design of many details based on aircraft construction reduce aerodynamic resistance.

State-of-the-art LED lighting technology contributes to active safety. Furthermore, it is controlled intelligently: daytime running lamps are automatically activated during the daytime. The Citylight system also senses when the forspeed driver turns night into day: photoelectric sensors monitor the brightness and give the command to automatically switch on the low-beam headlamps when necessary.
