Mercedes-Benz SLS AMG Coupé Electric Drive: Electrifying – the world’s most powerful electric super sports car
With the new SLS AMG Coupé 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 Coupé Electric Drive accelerates from zero to 100 km/h in 3.9 seconds.
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.
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.
The key data at a glance:
|SLS AMG Coupé 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,
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
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
Mercedes-Benz Concept B-Class Electric Drive: The electric Mercedes in the compact segment
A variant running on battery power alone is to be added to Mercedes-Benz’s range of compact cars in 2014. Mercedes-Benz will be offering an initial preview of the electric future for the B-Class at the 2012 Paris Motor Show in the guise of the Concept B-Class Electric Drive. Similarly to the successful B-Class models with conventional drives, the concept vehicle combines a comfortable and enjoyable driving experience with full suitability for everyday and family use. The so-called “ENERGY SPACE” in the floor ensures that the concept vehicle offers the same generous and variable space inside as the current series production models. The Energy Space provides a safe and space-saving means of accommodating the lithium-ion battery and also has a positive effect on the vehicle’s centre of gravity. The high-torque electric motor ensures that the local emission-free Concept B-Class Electric Drive is a lively proposition and guarantees hallmark Mercedes-Benz quality together with an enjoyable driving experience over a local emission-free range of 200 kilometres.
Local emission-free electric vehicles are a key element of the Mercedes-Benz strategy for sustainable mobility. The advances that the Stuttgart-based premium manufacturer has achieved in this field are demonstrated by electric passenger cars which are already being manufactured under series production conditions and demonstrating high everyday practicality today. Such vehicles include the B-Class F-CELL, the Vito E-CELL van and the smart fortwo electric drive. This broad product portfolio will be bolstered in 2014 by the addition of the battery-powered electric variant of the B-Class.
“In developing our electric vehicles we accord top priority to customer benefits,” says Professor Dr Thomas Weber, Member of the Board of Management at Daimler AG responsible for Group Research and Head of Mercedes-Benz Cars Development. “Accordingly, the Concept B-Class Electric Drive demonstrates premium-standard electric mobility for all the family. The concept vehicle offers outstanding everyday practicality and great driving enjoyment.”
Powerful acceleration and an effortlessly enjoyable driving experience
The near-series concept vehicle provides a glimpse of what the near future holds. Quiet and local emission-free drive power is provided by a 100 kW electric motor. Typically for an electric drive, the maximum torque of 310 Newton metres is available right from the first tap on the accelerator pedal – corresponding on a theoretical level roughly to the torque delivery of a state-of-the-art petrol engine with a displacement of three litres. This results in unusually powerful acceleration from a standing start. For the standard sprint from 0 to 100 km/h the electric-powered B-Class requires less than ten seconds. This adds up to superlative performance and all the joys of highly dynamic driving in every situation.
At a top speed limited to 150 km/h, the capacity of the highly efficient lithium-ion battery ensures a range of 200 local emission-free kilometres. This means that in addition to urban driving and short-range trips, longer journeys can also be mastered without any problems – such as the distances covered on a daily basis by commuters, for example. The Concept B-Class Electric Drive’s battery can be recharged at any standard domestic 230 V power outlet. A rapid charging function is also integrated which enables sufficient energy for 100 km to be charged in under an hour.
While the car is on the move, the electric drive itself contributes to a favourable energy balance by transforming kinetic energy into electric current in deceleration mode and during braking and feeding this energy into the battery (recuperation).
Elegant and sporty lines
The powerful lithium-ion battery on board the Concept B-Class Electric Drive is accommodated safely and compactly in the so-called “ENERGY SPACE” under the rear part of the vehicle. This intelligent space concept ensures that the five-seater retains its familiar generously sized interior and boot.
In terms of appearance, the Concept B-Class Electric Drive showcar differs to series production B-Class models in a number of details. These include first and foremost a striking front bumper and new side skirts which flow elegantly into both the front bumper and the newly designed rear bumper. The charging unit is installed inconspicuously behind the filler flap. A special reflective blue colour effect on the exterior highlights the Concept B-Class Electric Drive’s status as a local emission-free electric vehicle.
High-end comfort: exclusive interior
The range of instruments has been extended to cover functions specific to an electric vehicle. The round dial on the right incorporates a power display which is immediately and intuitively comprehensible, for example: the pointer rises when power is being consumed and drops below the zero line when the vehicle is feeding recuperative energy back into the battery. The instrumentation has been designed according to the motto “keep it clean”, i.e. avoiding any unnecessary electronic gadgets which might distract the driver unnecessarily from the traffic.
Soft nappa is predominant inside the vehicle, covering steering wheel, seats, door centre panels, armrests and the dashboard, which is bordered with carefully applied decorative turquoise blue stitching. The passenger compartment is finished in black, white and crystal grey. The perforated seat centre panels and armrests are in keeping with the showcar’s sporty, agile character. Special highlights are provided by fine piping in black, white and turquoise which provides a border for the light seat surfaces. The head restraints additionally sport an embroidered Electric Drive logo.
Cutting-edge technology ensures that the Concept B-Class Electric Drive is not only sustainable, but also fully networked and online. Remote checking and remote configuration of the vehicle is possible via the so-called Vehicle Homepage. The driver can access their vehicle on the internet, using their 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, showing directly whether and where the vehicle can be recharged along the way. The range of connected services is rounded off by a pre-entry climate control option offering individual timing. A further feature is smart charging. This involves the customer selecting a desired time for the beginning of his journey. The system then ensures that the battery is fully charged in time, taking economical and ecological considerations duly into account by using the most cost-effective or CO2-optimised charging times.
Big on safety
Mercedes-Benz attaches the same high safety standards to the Concept B-Class Electric Drive as apply to all the other series-produced vehicles of the MB brand. The very high safety standard of the new Mercedes-Benz B-Class provides the starting point. Thanks to the innovative “ENERGY SPACE”, the battery is accommodated under the floor at the rear of the vehicle, enhancing safety in the event of a crash.

Mercedes-Benz CLS Shooting Brake: Independence at its most beautiful
Jun 29, 2012 — Stuttgart. With the new CLS Shooting Brake, Mercedes-Benz is once again setting an example when it comes to creativity of design, and as such highlighting its leading role in this area: in terms of its proportions, the new CLS is quite clearly a coupé, but with five doors and a roof which continues through to the rear, it promises some remarkable new possibilities. The idea of the four-door coupé – successfully introduced in 2004 with the first CLS and long imitated in the meantime – has now been taken to new heights and to innovative effect. The result is automotive independence at its most beautiful.
According to CEO Dr. Dieter Zetsche: “Any memorable machine is equal parts art and science. A car has to first deliver in function – the ticket of entry – and then in fascination: the ticket to real excitement. The CLS Shooting Brake excels on both accounts – unlike any other car in the market”.
The proportions of the CLS Shooting Brake are surprising but clearly those of a coupé, and create a basic stance which makes it look ready for the off: the long bonnet, narrow-look windows with frameless side windows, and dynamic roof sloping back towards the rear. It is only when taking a second look that it becomes clear that the Shooting Break 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. “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 carpet, and the hand-stitched material is also incorporated into the sideliners in conjunction with leather appointments. Optional designer loading rails made of aluminium give an even more exclusive look.
An extravagant and unique feature for the automotive industry is the designo wooden luggage compartment floor, which serves to underscore the hand-finished nature of the interior. Cherry tree wood is a classic among fine wood species and contrasts perfectly with the inlaid smoked oak and aluminium rails. This affords the luggage compartment a touch of elegance normally found on yachts, combined with the exciting worlds of technology and precision craftsmanship. The wood is characterised by its flexibility and elasticity, as well as its density and fine texture. For the luggage compartment floor made of American cherry tree wood, selected veneer sheets are glued and pressed together by hand in five cross-bonded layers to achieve high dimensional stability. The blanks are milled into their precise shape using a CNC machine, and the surfaces sanded to a smooth finish and waterproofed to maintain the natural beauty of the wood. Inlaid work using darker smoked oak, precisely cut into three millimetre strips using laser technology, helps to enhance the design of the wooden 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 and also three qualities of leather to choose from. Customers have a choice of three exclusive wood types: high-gloss brown burr walnut, high-gloss black ash and satin-finish light-brown poplar. The interior is given an even more progressive look with the addition of piano lacquer or AMG carbon fibre/black piano lacquer trim elements. 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 icon 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 new dimension in vehicle concepts: the four-door Shooting Brake
No-one likes to have to compromise: even when the focus is not on the practical elements of the design of the Shooting Brake (length x width x height: 4956 x 1881 x 1413 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, Board Member of Mercedes-Benz Cars responsible for Sales & 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 beautiful.”
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, and in comparison with conventional steel doors, are some 24 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 four different engine variants – two diesel engines and two petrol engines. Features common to all engines include the 7G-TRONIC PLUS automatic transmission as well as the ECO start/stop function. In addition, two models are available with all-wheel drive: the CLS 350 CDI 4MATIC BlueEFFICIENCY and the CLS 500 4MATIC BlueEFFICIENCY.
The entry-level model is the CLS 250 CDI BlueEFFICIENCY producing 150 kW (204 hp). Combined fuel consumption is 5.3 litres of diesel per 100 kilometres, an excellent level for this performance class and equivalent to CO2 emissions of 139 grams per kilometre. Coming in above this are the two six-cylinder models: the CLS 350 CDI BlueEFFICIENCY producing 195 kW (265 hp) and the CLS 350 BlueEFFICIENCY producing 225 kW (306 hp). The top-of-the-range model is the CLS 500 BlueEFFICIENCY with a V8 biturbo engine producing 300 kW (408 hp).
Efficiency is also increased by the standard electro-mechanical power steering EPS (Electric Power Steering). EPS is a radical move in the relationship between the driver, car and road surface. This is because for the first time, it gives engineers the freedom to choose and programme many of the parameters that influence steering feedback. So they defined a Mercedes-Benz feeling behind the wheel. In addition to fuel economy, the result is a considerable improvement in handling and agility. The electromechanical power steering also enables another innovation to be implemented – Active Park Assist. The CLS Shooting Brake is not only able to detect parking spaces, but can also park automatically.
Another world exclusive: dynamic full LED headlamps
The CLS was the first passenger car in the world to offer optional dynamic full LED High Performance headlamps, which combine the exciting colour elements of LED technology – similar to those of daytime driving lights – with the performance, functionality and energy efficiency of today’s bi-xenon generation. Some 95 percent of all customers have opted for these lights in the CLS Coupé. Of course, as the world’s second car to feature this optional extra, the CLS Shooting Brake also offers the new light system. For the first time ever, it provides the Intelligent Light System already proven in Mercedes models fitted with bi-xenon headlamps 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 from Mercedes-Benz have for the first time been able to use LED technology in the innovative Adaptive Highbeam Assist, resulting in an entirely new quality of illumination when driving at night.
In contrast to the first 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 driving assistance systems help to 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.
It’s all in a name: the origins of the name “Shooting Break”
Break, or the homonym Brake, was the name once given to carriages used to “break” in wild horses and also to restrict (or “brake”) their urge to move, so that they could be put to use as work horses. Since the carts could easily be broken as part of this process, people tended not to use ones which they may have urgently needed for other purposes. Where necessary, “Brakes” were often fitted out with variable bodies, which were only really used to carry along anything that may have been necessary for the hunt, for example. Any such vehicle which was used when going out shooting was called a Shooting Brake or Shooting Break. Motorised Shooting Brakes were popular in England in the 60s and 70s – exclusive two-door sports cars, which combined the luxury and style of a coupé with a larger load compartment and large tailgate.
