Electric cars from Mercedes-Benz and smart are already covering the entire spectrum of individual mobility. This is underscored by the three new battery-electric drive vehicles celebrating their premieres at the 2012 Paris Motor Show. Together with the series-production version of the Mercedes-Benz SLS AMG Coupé Electric Drive and the smart BRABUS electric drive, the show also sees the premiere of the B-Class Electric Drive concept, a battery-electric variant of the B-Class. While both two-seaters set sporty accents – each in their own way – the electric B‑Class, due for market launch in 2014, presents a compelling case with its full everyday usability. Mercedes-Benz is setting further accents at the world’s most-visited motor show with the equally environmentally friendly B-Class Natural Gas Drive, as well as the new A-Class, which is already enjoying a very successful market debut here in France.“Three new electric cars in three different segments – a wonderful demonstration of our broad-ranging e-mobility line-up. Our new electric SLS of course symbolizes the dynamism of the Mercedes-Benz brand in a particularly impressive fashion,” says Dr. Dieter Zetsche, CEO of Daimler AG and Head of Mercedes-Benz Cars. The three electric cars shown in Paris come with the suffix “Electric Drive” in their model designations. In future, this lettering will grace the rear lid of all battery-electric passenger vehicles from Mercedes‑Benz, Mercedes-AMG and smart.
The B-Class Electric Drive concept combines comfortable driving fun with full everyday and family usability. It is driven by a 100 kW electric motor, which delivers exceptional dynamics plus a range of 200 kilometres thanks to its powerful torque of 310 Newton metres. Ensuring that the generous and variable interior space remains unaffected is the “ENERGY SPACE” in the vehicle floor in front of the rear axle. It provides a space-saving and secure location for the lithium-ion battery, while also benefitting the vehicle’s centre of gravity.
“Electric cars are a significant component of our strategy for sustainable mobility,” says Prof. Dr. Thomas Weber, Member of the Board of Management of Daimler AG, Group Research and Mercedes-Benz Cars Development. “In the B-Class, we have an extremely versatile compact car that is well-suited to a variety of different drives – from internal combustion engines through pure battery-electric drive to fuel cells. Thanks to the ENERGY SPACE, the B-Class is the Mercedes pioneer for alternative drives in the compact premium car segment.”
SLS AMG Coup̩ Electric Drive Рthe most powerful super sports car with electric drive
Mercedes-AMG is launching a whole new era with the new SLS AMG Coup̩ Electric Drive Рthe zero-local-emissions super sports car with Formula 1 high-tech is the most exclusive and dynamic way to drive an electric car. The most powerful of all AMG high-performance vehicles is equipped with four electric motors delivering a total output of 552 kW and maximum torque of 1,000 Nm. These vital statistics make the gullwing the fastest electric-drive series-production vehicle in the world Рthe SLS AMG Electric Drive completes the sprint from zero to 100 km/h in just 3.9 seconds.
A super start for the new A-Class – 70,000 advance orders in Western Europe
A further Mercedes highlight in Paris is the new A-Class, which is already enjoying a very successful market debut in France. More than 60,000 potential customers came to the market launch in the showrooms of French Mercedes dealerships. A total of around 700,000 visitors took part in the market premiere. Dieter Zetsche: “We have taken around 70,000 advance orders in Western Europe alone. This makes the market premiere of the new A-Class the most successful experienced by Mercedes-Benz to date.”
The new A-Class has an exceptionally emotional design, with dynamic engines ranging from 80 kW (109 hp) to 155 kW (211 hp). It is highly efficient, with emissions figures starting at 98 g CO2/km, it has a best-in-class cd value of 0.27 and boasts exemplary safety. The list of standard equipment includes the radar-guided assistance system COLLISION PREVENTION ASSIST. The petrol engines and the top diesel unit already fulfil the EURO 6 standard, setting the benchmark for clean exhaust emissions..jpg)

Mercedes-Benz sculpture "Aesthetics S": A modern sense of status and sensual shapes
With its sculpture entitled "Aesthetics S", Mercedes-Benz is providing an artistic glimpse of the design of the luxury saloon of the foreseeable future. The aesthetics of the relief-like sculpture are combined with an exciting projection display. In the eyes of the observer, this creates a three-dimensional world and enables the creative imagination of the designers to be visualised to impressive effect. The modern production in three acts, developed by the Mercedes-Benz designers, will be on display in Hall 1 at the Paris Motor Show.Since the 1930s, the respective top-of-the-range model from Mercedes-Benz has played a very special role - not only for Mercedes-Benz, but also for the automotive world in general. An S-Class does not merely represent the latest state of the art, and as such acts rather more as a symbol and role model for the motor car. "The characteristic lines of the S-Class have always represented the expression of automotive culture, as we understand it. The new S-Class will continue this tradition and, with its striking lines, will put a face to our design philosophy over the coming years", explains Gorden Wagener, Head of Design at Mercedes-Benz Cars.
Sculptural shapes, which are given structure and an element of excitement through characteristic lines, are a classic feature of Mercedes-Benz design. Reducing them to a relief-like design incorporating the main elements of the sidewall makes the power and significance of the lines visible and perceivable. In the case of the "Aesthetics S" sculpture, the exterior of a future luxury saloon is interpreted in an artistic manner. According to Wagener: "The sculpture highlights the artistic aspects of design. With the design and proportions of "Aesthetics S", we are communicating a modern sense of status, sensual shapes and stylish sportiness."
The debut of the relief-like sculpture at the Paris Motor Show will be combined with an exciting projection display. The scene will be set for the sculpture with the aid of light in a series of three acts, using a modern means of design and implementation. The shape will be revealed through projected light reflections, creating a three-dimensional world in which the creative imagination of the designers can be visualised to impressive effect. In addition to the organic, naturally-occurring flowing forms which act as a source of inspiration to the designers, it will also possible to appreciate the scope of impact exerted by the S-Class tradition. This is to be achieved by incorporating four S-Class models from past decades – namely the model series 189, 108, 126 and 221. According to Wagener: "The Mercedes-Benz S-Class has always impressed with its timeless design, which has existed for decades and has always pointed the way ahead. The sculpture is a continuation of this, and sets the scene for the development of a new S-Class."
With the "Aesthetics S" work of art, Mercedes-Benz is continuing its "Aesthetics" series of sculptures which to date comprises the pieces "Aesthetics No. 1" (2010), "Aesthetics No. 2" and "Aesthetics 125" (both 2011)..jpg)

With the new A-Class, Mercedes-Benz is opening up a new chapter in the compact segment: markedly emotive in design, with powerful engines ranging from 80 kW (109 hp) to 155 kW (211 hp), extremely efficient with emissions from just 98 g of CO2/km and a best-in-class drag coefficient of 0.27. At the same time the new model underlines that for Mercedes-Benz, safety is not a question of price – the standard specification includes, amongst other things, the radar-based COLLISION PREVENTION ASSIST system. "Mercedes-Benz is becoming the most dynamic premium brand in the world. As part of this development, the A-Class represents an important milestone. The A-Class is completely new, down to the last detail. In automotive development, it's not often you get the chance to start with a clean sheet of paper. Our engineers have made the very most of that opportunity", explains Dr Dieter Zetsche, Chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz Cars.
The design: the most progressive in the compact class
Standing as much as 180 millimetres lower on the road than the preceding model, the new A-Class communicates design and dynamism at the very first glance. This radical form language, presented and enthusiastically acclaimed around the world with the Concept A-CLASS, was consistently implemented in the series production car. The appearance of the new A-Class reflects this new Mercedes-Benz design strategy. The result is what is known as a two-box design with a distinct character of its own, a sportily emotive exterior and an exceptionally high-quality feel to the interior.
"Translating the new dynamic style of Mercedes-Benz into the compact class was a challenge that was great fun to tackle", explains Gorden Wagener, Head of Design at Mercedes-Benz Cars. "No other car in this segment is as progressive as the A-Class. Absolutely typical for Mercedes is the sculptural shape of the A‑Class. The character lines, in particular on its sides, lend the A-Class structure and terseness. The new dynamic style is perceptible at first glance in the interior as well."
Defined edges and tautly drawn surfaces mark out the exterior design of the new A-Class. The constant interplay between concave and convex surfaces creates a characteristic play of light, particularly along the sides of the car, which contributes to its unique appearance.
Typical features of the long, sporty front are its pronounced V-shape, the separate headlamps, the radiator grille with central Mercedes star and double slats to either side of the star, as well as the additional air intakes on the sides. The "dropping line" apparent in the side profile dissipates towards the vehicle's front end. The design of the headlamps, together with the configuration of the light functions within them, are key elements of the design concept. The light modules and LEDs behind the headlamp cover glass have been arranged in such a way as to create the characteristic "flare effect" for the daytime driving lights and indicators.
The perfect interplay of dynamic design and excellent aerodynamics is nowhere more apparent than in the roof, with its smooth surfaces and taut, arcing curve. The silhouette reveals smooth, flowing lines finishing in a flat edge. The roof spoiler, which conveniently hides all the aerials, provides an extra sporty touch and gives structure to the roof assembly.
The broad emphasis of the tail end is revealed in an interplay of convex-concave surfaces and edges. The tail lights continue the line of the muscular shoulders back towards the rear, while their horizontal orientation emphasises the car's powerful width. The light functions are provided optionally by fibre-optic cables and LED modules. Here, too, the interaction between design and aerodynamics is very clear: the surface finish of the tail lights is not only an interesting design feature, but also improves the airflow around the vehicle thanks to defined airflow break-away edges in the rear section.
Interior: five-seater model with a high-value impression
The interior of the A-Class represents a big step forward in terms of quality – both in the materials used and in the consistency of the design. Both objectives have been achieved with the help of a specific design idiom and through the various combination options possible with the high-quality materials selected. All trim elements have been given an electroplated finish, resulting in real metal surfaces with "cool touch" effect. The work has been executed with considerable care and attention to detail, so that they appear to have been moulded in one piece.
The instrument panel incorporates five round vents. The outer rings of the round vents have a high-quality electroplated finish. The airflow direction is governed by an insert that is reminiscent of an aircraft turbine and reveals a meticulous attention to detail. This too has an electroplated finish in silver-chrome. The free-standing display screen features a black piano-lacquer-look front panel and a flush-fitting silver frame.
The instrument cluster comprises two large round instruments, each with a small dial set within it. When at rest, the dial needles stand at 6 o'clock. The pointer inlays are in white, although with the sportier design and equipment lines such as Urban and AMG Sport they are in red. The dials on the sporty equipment lines and packages are silver with a chequered flag effect. The 3-spoke steering wheel comes with 12 function buttons and an electroplated bezel.
The fact that the new A-Class is a sporty hatchback model with a low centre of gravity is reflected in its dimensions: measuring 4292 x 1780 x 1433 mm (length x width x height), it hugs the road. Compared with its predecessor, which followed a different design, the height has been reduced by 180 millimetres.
The A-Class is a five-seater model. The rears seats provide room for three passengers, despite looking like two individual seats with their sporty design. The boot volume is 341 litres, based on the VDA standard. If the rear seat backrests are folded down, its capacity jumps to 1157 litres. In all models the seat backrests feature a 60:40 split can be folded forward individually. The width of the luggage compartment between the wheel housings is 1050 mm.
The model range: young and individual
With air conditioning, Audio 5 USB, electric windows all round, Headlamp Assist and 12-button multifunction steering wheel, the A-Class is already fully equipped even in its base configuration. With "Urban", "Style" and "AMG Sport" appointment lines, three Design packages ("Night", "Exclusive" and "AMG Exclusive") as well as further optional extras, the model can be customised to suit every individual taste.
Available appointments, many familiar from higher vehicle classes, include the Intelligent Light System, electrically adjustable front seats with memory function or dashboard finished in ARTICO man-made leather (part of the Exclusive package). All three appointment lines feature front sports seats with integrated head restraints and contrasting stitching, and can be combined with all engine variants.
Further sporty details designed to appeal to the vehicle's young target group include designo seat belts in red (available from December 2012) or silver instrument cluster with red dial pointers (part of the Urban and AMG Sport lines as well as the Exclusive and AMG Exclusive packages).
"The new A-Class is the heartbeat of a new generation at Mercedes-Benz", stresses Dr Joachim Schmidt, Member of the Board of Management of Mercedes-Benz Cars responsible for Sales & Marketing. "We have taken the opportunity to design a completely new vehicle which sets standards in its segment. I am convinced that the new A-Class will make a significant contribution to our Mercedes-Benz 2020 growth strategy."
Drive system: high output, low consumption
A wide choice of petrol and diesel engines meets every power requirement and reaches new heights in terms of efficiency and environmental compatibility: the A 180 CDI will be the very first Mercedes-Benz to emit only 98 g of CO2 per kilometre. Moreover, the A 220 CDI (available from December 2012) already meets the Euro 6 emission standard which only comes into force in 2015. All engines of the new A-Class feature the ECO start/stop function as standard. The engines can be combined with the new six-speed manual transmission or optionally with the 7G-DCT dual clutch automatic transmission, which ideally combines comfort and sportiness. Fuel consumption down by up to 35 percent compared to comparable preceding models, accompanied by a considerable power increase: these are the salient features of the engine range for the new A-Class.
Diesel engines: three efficient power bands
The new basic engine in the OM 607 series develops 80 kW (109 hp), delivers 260 Nm to the crankshaft and with a manual transmission consumes 3.8 litres per 100 km, corresponding to 98 g of CO2/km. This is a 22-percent improvement over the only 60 kW (82 hp) preceding model, the A 160 CDI, which consumed 4.9 litres. The new top diesel, the A 220 CDI, is no less than 25 percent better than its predecessor: it develops an output of 125 kW (170 hp) and 350 Nm of torque, and in combination with the 7G-DCT automatic dual clutch transmission it consumes only 4.3 litres/100 km (provisional figure). The figures for the preceding A 200 CDI were 103 kW (140 hp), 5.7 litres, and 149 g of CO2/km.
Petrol engines: turbocharging and direct injection for all
A comparison between the new and previous A 200 demonstrates what has been achieved with the petrol engines: with 115 kW (156 hp) and 250 Nm of torque, the new engine delivers superior performance but consumes only 5.4 litres/100 km (127g CO2/km – figures for the 7G-DCT), which is 26 percent less than its predecessor (100 kW, 185 Nm, 7.4 l/100 km, 174 g CO2/km). Even the new top model with the 7G-DCT and producing 155 kW (211 hp) and 350 Nm is considerably more efficient with a consumption of 6.1 litres and CO2 emissions of 143 g.
The completely new engines and transmissions are not the only decisive factors in this exemplary efficiency. Thanks to the modular system it has been possible to select the optimally designed transmission for each diesel and petrol engine. The overall package is rounded off perfectly with progressive aerodynamics with a Cd figure of only 0.27, as well as a number of other improvements.
"The new four-cylinder models from Mercedes-Benz occupy a leading position by virtue of their performance, high efficiency and very low emissions. They impress with their smooth, superior power delivery and offer customers refinement at the highest level," says Professor Dr Thomas Weber, Daimler Board Member responsible for Group Research and Mercedes-Benz Cars Development.
Suspension: agility and refined sportiness
Refined sportiness means maximum agility combined with the sense of safety, unspoilt driving stability and high levels of ride comfort which are all typical of the brand. The suspension of the new A-Class has a four-link rear axle, electromechanical power steering with assistance functions and ESP® with "Extended Traction Control" (XTC). During development, the suspension experts made intensive use of simulations and the driving simulators at the Mercedes development centre in Sindelfingen as part of the so-called digital ride and handling test.
The preconditions for achieving dynamic handling are excellent in the A-Class. This is because compared with its predecessor the centre of gravity (40 mm lower) and seating position (178 mm lower) has been reduced significantly. A new feature is the four-link rear axle: forces are absorbed by three control arms and one trailing arm per wheel. This means that longitudinal and lateral dynamics are virtually independent of one another. Wheel carriers and spring links are made of aluminium to reduce the unsprung masses. The goal was to achieve high lateral agility with high driving stability thanks to small sideslip angle on the rear axle.
Three chassis and suspension set-ups are available: the comfort suspension and optional sports suspension for sporty yet comfortable handling (in conjunction with the Dynamic Handling package or the AMG Sport equipment line). In addition, the A 250 Sport has a sporty, "engineered by AMG" high-performance suspension. Altogether this results in low dynamic rolling behaviour and low start-off pitch angle. Furthermore, the vehicle also has a reduced tendency to understeer in the higher lateral acceleration range: the driver is therefore able to control changes in direction with low steering input but high steering precision. When accelerating out of bends taken at speed, the tendency to understeer is reduced even further by "Extended Traction Control" (XTC): with this function, ESP® provides support in the form of directional stability by generating a yaw moment on the front and rear wheels located on the inside of the bend.
Safety: setting the very highest standard
In an innovative move in the compact segment, the A-Class is equipped as standard with a radar-based collision warning system with adaptive Brake Assist, a combination which lowers the risk of rear-end collisions. The COLLISION PREVENTION ASSIST system gives a visual and audible warning to alert a possibly distracted driver to identified obstacles, and prepares Brake Assist for the most precise braking response possible. This is initiated as soon as the driver operates the brake pedal decisively.
"With the new A-Class, Mercedes-Benz is setting new standards in many disciplines, not least when it comes to the area of safety", emphasizes Prof Dr Thomas Weber, Daimler Board Member responsible for Group Research and Head of Mercedes-Benz Cars Development. "The new A-Class provides the highest standard of safety ever seen in this vehicle class."
The democratisation of safety encompasses an array of assistance systems which have been adopted into the A-Class from the larger model series, or sometimes developed further in the A-Class. These include:
- Adaptive Highbeam Assist
- Blind Spot Assist and Lane Keeping Assist
- ATTENTION ASSIST (standard)
- Speed Limit Assist (speed limit sign recognition)
- Active Parking Assist with parking guidance
- Brake hold function
- Hill-Start Assist
- LINGUATRONIC
- Reversing camera
- DISTRONIC PLUS
Premiere in the compact class: PRE-SAFE® available for the first time
The availability of the PRE-SAFE® anticipatory occupant protection system for the A-Class marks another first in this vehicle category. This represents a further step in the on-going democratisation of this innovation, which was premiered in the S-Class in 2002. Core features of PRE-SAFE® are reversible belt tensioning, the closing of side windows and sliding sunroof in case of critical lateral dynamics and adjustment of the fully electric front passenger seat with memory function to an ideal position for maximum effectiveness of the restraint systems. PRE-SAFE® is always activated in response to critical longitudinal and lateral dynamics and may also be triggered upon intervention by certain assistance functions.
Body: a strong basis and intelligent protection
The new A-Class has passed the brand's rigorous programme of crash tests. This includes not only some 30 different impact configurations, which are laid down as requirements for safety ratings and international type approval, but also nine proprietary crash tests, such as the roof-drop test or the pole impact test, developed by the brand itself.
The ability of the new A-Class to satisfy requirements which go far beyond the statutory conditions in some cases is also demonstrated by an internal offset front collision test against a future luxury-segment saloon from Mercedes-Benz: despite the high impact speed and the fact that it is the smaller accident participant, the A-Class offers its occupants an intact passenger compartment and excellent chances of survival.
The scope of the restraint systems takes special account of the A-Class's use as a family car. Great importance has been attached to the safety of the rear occupants. Belt tensioners, belt-force limiters and belt height adjusters come as standard on the outer seats. Rear sidebags are optionally available. The driver and front passenger are provided with new thorax-pelvisbags which are able to cover the pelvis and the entire upper part of the body. A windowbag is fitted as standard for head protection.
Comprehensive iPhone® integration
This seamless integration of the iPhone® into the vehicle, in conjunction with the new revolutionary user interface design, means that Mercedes-Benz is now able to offer the Facebook generation its natural home on four wheels in the guise of the new A-Class. Along with Facebook, Twitter and so on, the "Drive Kit Plus for the iPhone®" (expected to be available as an accessory from September and as an optional extra from the first quarter of 2013), together with the Daimler app concept, brings further digital lifestyle services and content into the vehicle. Highlights include advanced navigation software from Garmin, with internet-based real-time traffic information, online destination searches and 3D map display.
The Drive Kit Plus for the iPhone® can already be used with the Audio 20 CD. This features a twin tuner and mp3-capable CD player as well as a Bluetooth interface with hands-free function and audio streaming. The colour display measures 14.7 cm diagonally. Thanks to a new "Cover Art" function, the title images of the music albums currently being played are shown if their details are stored in the audio file.
The Becker® MAP PILOT makes a low-cost 3D navigation function, which can also be retrofitted, available for the Audio 20 CD radio. The navigation system boasts voice-controlled input of destinations and an intuitive user interface. Its advantages over aftermarket solutions include integrated operation via the central controls and the Audio 20 CD display, a concealed location in the glove compartment and updating via an internet portal.
The multimedia system COMAND Online now provides internet access via a web-enabled mobile phone, plus various Mercedes-Benz services on the move. These include weather information and a special destination search via Google, as well as the option of downloading a route that has been previously configured on a PC using Google Maps and sent to the car. A new feature is the "News" app which enables news on politics, finance and technology to be called up online in the vehicle. Information is displayed in such a way that it is clearly legible while on the move..jpg)

The new CLS Shooting Brake sees Mercedes-Benz making its mark once again with a creative design concept that underscores its leading role in the design field: while unmistakably coup̩ in its proportions, the new CLS opens up a wealth of new possibilities with five doors and a roof extending back all the way to the rear end. As such, the new Shooting Brake represents an innovative development of the four-door coup̩ concept, which was successfully introduced with the first CLS in 2004 and has since provided the template for numerous copycat designs. The result is automotive independence at its most beguiling."Every genuine car legend appeals equally to the heart and mind," observes CEO Dr Dieter Zetsche. "Functionality is obligatory for a vehicle Рour customers take this for granted. What sets a car apart is a special fascinating quality. The CLS Shooting Brake combines functionality and fascination in a way that is unmatched by any other automobile."
Surprising yet unequivocally coupé, the CLS Shooting Brake's proportions create a crouched posture, as if the vehicle were poised to make a leap: long bonnet, narrow window profile with frameless side windows, roof sloping dynamically towards the rear and continuing to the tail end of the vehicle. It is only when taking a second look that it becomes clear that the Shooting Brake actually has five doors and offers more in terms of function.
In essence it represents an unprecedented version of a sports car with five seats and a large tailgate. It is a special proposition for people looking to differentiate themselves from the mainstream, and who do not wish to compromise on either sportiness or stowage space when it comes to travelling in style. The Shooting Brake is a further highlight in the innovative luxury vehicle series from Mercedes-Benz and, like the CLS Coupé, has the potential to become the role model for a new market segment.
"The CLS Shooting Brake is based on the great tradition of stylish sportiness which has always characterised Mercedes, and takes these unique icons an exciting step further", explains Gorden Wagener, Head of Design at Mercedes-Benz Cars. "It stands for the enhanced design idiom of Mercedes-Benz which is oriented towards aesthetic, avant-garde principles". This is seen in the impressive series of market-defining new vehicle concepts, such as the SLK for example, which in 1996 established a genre as the first Roadster with a retractable steel roof, the M-Class as the first premium SUV in 1998, or the first four-door CLS Coupé in 2004.
Exclusive innovation in the interior: wooden luggage compartment floor
The second generation of the CLS set high standards in terms of the design and quality of the interior: straightforward elegance combined with innovative details and handcrafted perfection. The Shooting Brake also applies this same aspiration in the luggage compartment. It is lined with high-quality carpeting, and the hand-stitched material is also incorporated into the sideliners in conjunction with Exclusive PASSION leather appointments. Optional designer rails made of aluminium on the luggage compartment floor give an even more exclusive look.
An extravagant touch is the designo wood luggage compartment floor, which highlights the interior's hand-crafted character. The American cherry wood is a classic fine wood variety which contrasts effectively with the fumed oak inlaid work and the aluminium rails. This lends the luggage compartment the elegance of a yacht's wooden deck combined with the fascination of high-tech and precision workmanship. The wood is characterised by its flexibility and elasticity, as well as its density and fine texture.
For the American cherry wood luggage compartment floor, specially selected veneer sheets are glued and pressed by hand in five layers to attain a high level of dimensional stability. The blanks are milled to their exact format using a CNC machine and the surfaces are ground smooth and impregnated to bring out the wood's natural beauty. Dark fumed oak inlays, precision-cut in narrow three-millimetre strips using laser technology, lend a definitive finishing touch to the design of the luggage compartment floor. The lavishly produced aluminium rails have a brushed finish and rubber inserts, and not only help to protect the wooden floor but also feature anti-slip properties.
The CLS Coupé already set new standards in interiors with its wide variety of individualisation options. The Shooting Brake also offers five interior colours, five trim designs plus three qualities of leather to choose from. Customers have a choice of three exclusive wood types for the trim: high-gloss brown burr walnut, high-gloss black ash and satin-finish light-brown poplar. Black piano lacquer trim is also optionally available. The interior is given an even more progressive look by the AMG trim features in carbon fibre in combination with black piano lacquer. A completely new addition comes in the form of "porcelain" interior appointments which afford both CLS models a sense of luxury normally found in the S-Class. The CLS Shooting Brake also lives up to its role as a design trend-setter thanks to the innovative nature of the materials used. These comprise a mixture of satin and high-gloss finishes used on the metal surfaces.
A whole new vehicle concept: the four-door Shooting Brake
No-one likes to have to compromise: even though the focus is not on the practical elements of the design of the Shooting Brake (length x width x height 4956 x 1881 x 1416 mm), the new CLS model still has some trump cards up its sleeve. With a load volume of between 590 and 1550 litres, the luggage compartment offers a lot of room despite the flat, sporty lines of the roof, and is easy to use thanks to the automatically opening tailgate fitted as standard. A load compartment cover also protects luggage from prying eyes.
The standard air suspension at the rear helps to ensure optimum road holding at all times. For additional flexibility, the rear seat backrests can be folded down from the luggage compartment as standard. The rear seats themselves provide room for three people, with individual seats on the outsides and a third seat in the middle. The three saddle-type head restraints on the rear seats barely affect the view towards the rear, and can be lowered at the touch of a button by the driver. An optional trailer coupling is also available.
Dr Joachim Schmidt, Executive Vice President Mercedes-Benz Cars, Sales and Marketing, sums it all up: "The new CLS Shooting Brake represents a new dimension in vehicle concepts and offers discerning customers independence at its most beguiling."
Lightweight construction and aerodynamics: important contributions to efficiency
Intelligent lightweight construction plays a decisive role in bridging the classic conflict between the objectives of low weight and high strength in the CLS Shooting Brake. The model features frameless, all-aluminium doors made from deep-drawn aluminium panels with extruded sections, which in comparison to conventional steel doors are some 32 kilograms lighter. The tailgate, bonnet, front wings, various support profiles and substantial parts of the suspension and engines are all made of aluminium too.
The aerodynamics also make a significant contribution to the efficiency of the Mercedes-Benz CLS Shooting Brake. With a frontal area of 2.30 m² and a Cd value of 0.29, the drag area is 0.67 m².
Drive system: powerful and efficient
The CLS Shooting Brake is available with five engine variants – two diesel and three petrol engines. All engines come together with a 7-speed automatic transmission and the ECO start/stop function as standard. Two models with all-wheel drive are additionally available: CLS 350 CDI 4MATIC BlueEFFICIENCY and CLS 500 4MATIC BlueEFFICIENCY.
The entry-level model is the CLS 250 CDI BlueEFFICIENCY, with a power output of 150 kW (204 hp). Fuel consumption in combined mode is outstanding for this power category, at 5.3 litres of diesel per 100 kilometres, corresponding to CO2 emissions of 130 grams per kilometre. On the next level come the two six-cylinder engines: CLS 350 CDI BlueEFFICIENCY, rated at 195 kW (265 hp) and CLS 350 BlueEFFICIENCY at 225 kW (306 hp), while the CLS 500 BlueEFFICIENCY with V8 biturbo engine has a power output of 300 kW (408 hp).
The dynamic top model of the Shooting Brake range is the CLS 63 AMG Shooting Brake, fitted with an AMG V8 biturbo engine rated at 386 kW (525 hp) which delivers 700 Newton metres of torque and comes with the AMG SPEEDSHIFT MCT 7-speed sports transmission. With the "Edition 1" variant, these performance values rise to 410 kW (557 hp) and 800 Newton metres.
The combination of AMG RIDE CONTROL sports suspension with electronically controlled damping, electro-mechanical AMG speed-sensitive steering and the optional AMG ceramic high-performance composite brake system is the epitome of superlative driving dynamics. In terms of appearance, the CLS 63 AMG cuts an impressive figure with its athletic lines and its distinctive exterior and interior design.
Efficiency is also increased by the stand-fit electro-mechanical Direct-Steer system. This represents a radical development in the relationship between the driver, car and road surface. For the first time, it gives engineers the freedom to choose and programme many of the parameters that influence steering feedback. They were thus able to define a Mercedes-Benz feeling behind the wheel. In addition to fuel economy, the result is a considerable improvement in handling and agility. The electromechanical Direct-Steer system has also made Active Park Assist possible. The CLS Shooting Brake is not only able to detect parking spaces, but can also park automatically.

The CLS Coup̩ was the first passenger car in the world to offer optional dynamic LED High Performance headlamps, which combine the exciting colour elements of LED technology Рsimilar to those of daytime driving lights Рwith the performance, functionality and energy efficiency of today's bi-xenon generation. Some 95 percent of all customers opt for these lights in the CLS Coup̩. The CLS Shooting Brake is also optionally available with the new light system. It offers the proven Intelligent Light System in combination with LED technology. The headlamps, with their 71 LED lamps in total, look exciting; and they serve to underline the unmistakable appearance of the CLS. The light specialists at Mercedes-Benz have additionally managed to combine the LED technology with Adaptive Highbeam Assist, resulting in a totally new quality of illumination at night.
In contrast to other vehicles equipped with LED headlamps, no compromises are now necessary with respect to the functionality and performance of the lighting technology. There are further arguments for LED-based lighting technology: the average operating life of an LED is around 10,000 hours, around five times longer than that of a xenon light; moreover, LED headlamps most closely approximate to the colour of daylight. This means that LED light is in keeping with the normal human perception patterns and that the driver experiences significantly more brightness on the road at night. Studies have shown that the closer the colour of artificial light comes to daylight, the less the strain on the eyes. With a colour temperature of 5500 kelvin, LED light is closer to daylight (6500 K) than xenon light (4200 K).
More than a dozen driver assistance systems are able to help prevent traffic accidents and reduce the severity of an accident. Active Blind Spot Assist and Active Lane Keeping Assist are available as part of the Driving Assistance package Plus, in combination with DISTRONIC PLUS, BAS PLUS and the PRE-SAFE® Brake. Both assistance systems are not only able to detect an unintentional lane change or vehicles in the blind spot, but can also correct the direction of travel by gentle brake intervention if the driver ignores the visual or audible danger warnings..jpg)

With the new SLS AMG Coup̩ Electric Drive, Mercedes-AMG is entering a new era: the locally emission-free super sports car featuring advanced technology from the world of Formula 1 is the most exclusive and dynamic way in which to drive an electric car. The most powerful AMG high-performance vehicle of all time has four electric motors producing a total output of 552 kW and a maximum torque of 1000 Nm. As a result, the gullwing model has become the world's fastest electrically-powered series production vehicle: the SLS AMG Coup̩ Electric Drive accelerates from zero to 100 km/h in 3.9 seconds. A new dimension of driving performance Рa 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 Coup̩ 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.
Enormous thrust thanks to 1000 Nm of torque
The pioneering drive package in the SLS AMG Coup̩ 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 Рmaximum 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.The key data at a glance:
Powerful, voluminous, dynamic, emotional and authentic: the characteristic sound of the SLS AMG Coup̩ 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 Рthis 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 Coup̩ Electric Drive boasts an energy content of 60 kWh, an electric load potential of 600 kW and weighs 548 kg Рall 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 Рthe intelligent and permanent all-wheel drive of the SLS AMG Coup̩ 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 Coup̩ 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 Рmeasuring 402 x 39 mm at the front and 360 x 32 mm at the rear Рare 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
