The new Mercedes-Benz M-Class: Champion of refined efficiency

The third generation Mercedes-Benz M-Class scores particularly highly on outstanding energy efficiency, and on average the new model range consumes 25 percent less fuel than the previous models. One true champion in terms of fuel consumption is the ML 250 BlueTEC 4MATIC, which boasts an NEDC consumption of just 6.0 l/100 km (158 g CO2/km) and has a range of up to 1500 kilometres on a full tank. Further strengths of the premium SUV with permanent all-wheel drive include exceptional safety and well-balanced ride comfort as well as excellent driving dynamics both on and off the road. What's more, the ML features an array of new chassis developments and innovative dynamic handling control systems which further enhance both driving enjoyment and handling safety. A characteristic body design and a variable interior with a high wellness factor add to the richness of the driving experience in the new M-Class.



Dr. Thomas Weber, member of the Board of Management of Daimler AG with responsibility for Group Research and Mercedes-Benz Cars Development, puts it in a nutshell: "With the M-Class, it's always been a case of combining the comfort and luxury of a saloon car with the off-road characteristics and the emotiveness of an SUV." The fact that the new M-Class is as fuel-efficient as the economical saloon cars displaying the Mercedes star makes the all-wheel-drive model even more desirable. A range of state-of-the-art engines, a class-leading cd figure (drag coefficient) of 0.32 and extensive BlueEFFICIENCY measures lay the foundations for outstanding energy efficiency.

2012 Mercedes-Benz M-Class

Complete and attractively priced model range

According to Dr. Joachim Schmidt, Board Member of Mercedes-Benz Cars, Sales & Marketing: "The M-Class is a story of success. With more than 1.2 million vehicles sold, it is the best-selling SUV in its segment and also enjoys the loyalest customer base. We will be continuing this success with the new M-Class, which will make an important contribution to our sales growth over the coming years."



To mark the launch of the new M-Class, there will be a limited special-edition model available in the shape of the Edition 1. This exclusive model includes an AMG Exterior Sports package and features an impressive and particularly exclusive interior. Prices start at €55,700 (€66,283 incl. 19% VAT) for the ML 250 BlueTEC 4MATIC Edition 1. Delivery of the M-Class to customers will commence in November this year.



A model of success: the M-Class sets new standards in the world of the SUV

BlueTEC diesel units and the new generation of BlueDIRECT petrol engines ensure excellent economy and an outstanding life cycle assessment of the new M-Class. As Dr. Schmidt explains further: "The new M-Class has the potential to set standards in the SUV world once again: one average it consumes one quarter less fuel than its predecessor and as such will be the most economical vehicle in its segment - whether fitted with or without a hybrid drive."



As far as the diesel engines are concerned, now available solely as BlueTEC units with SCR emissions technology, the focus is firmly on downsizing and on the new version of the V6 CDI engine:

- In the ML 250 BlueTEC 4MATIC, the 3.0-litre V6 of the previous ML 300 CDI BlueEFFICIENCY 4MATIC model is replaced by the thrifty four-cylinder unit already familiar from, for instance, the S-Class. The NEDC consumption of 6.0 l/100 km is 28 percent lower than that of the previous model.

- The ML 350 BlueTEC 4MATIC features an extensively revamped 3.0- litre V6 which offers far better performance coupled with a substantial reduction in fuel consumption. This version boasts an NEDC figure of just 6.8 l/100 km, a 24-percent improvement compared to the previous ML 350 CDI 4MATIC model.





Thanks to AdBlue® emission control technology both diesel models comfortably meet the EU6 standard slated for introduction in 2014.

The ML 350 4MATIC BlueEFFICIENCY petrol-engine model, on the other hand, delivers a convincing performance thanks to the technical details of the new BlueDIRECT engine generation. The key here is the third-generation direct petrol injection system with spray-guided combustion and new piezo injectors that have an injection pressure of 200 bar, together with multi-spark ignition (MSI) and a new stratified combustion process. In this case, the NEDC consumption of 8.5 l/100 km is 25 percent lower than that of the previous ML 350 4MATIC model. The ML 350 4MATIC BlueEFFICIENCY meets the requirements of the EU5 standard, currently the strictest standard in force for petrol models.



Long-distance champion: a high level of efficiency ensures a long range

The range calculated for a full tank of fuel is particularly impressive. With an NEDC consumption of 6.0 l/100 km, the ML 250 BlueTEC 4MATIC with the standard 70-litre tank can cover around 1170 kilometres before needing to stop for fuel. If the vehicle is fitted with the optional 93-litre tank, the car can even cover up to 1500 kilometres between refuelling stops.



The excellent fuel economy is underpinned by a comprehensive package of BlueEFFICIENCY measures as well as by this state-of-the-art engineering. In addition to the ECO start/stop function that comes as standard, these measures include the new seven-speed 7G/TRONIC PLUS automatic transmission with a new fuel-economy converter, friction-optimised bearings and a transmission oil thermal management system. Low-friction axle drives, electric steering, the optimised belt drive with decoupler, the on-demand control of all ancillary components and pumps, and tyres with low rolling resistance also play their part in reducing fuel consumption. What's more, intelligent lightweight design has stopped the weight from spiralling upwards.



With a drag coefficient, or cd figure, of 0.32, the new M-Class (ML 250 BlueTEC) also sets a new best figure for this vehicle class. Intensive simulations undertaken with the digital prototype, along with final touches added in the wind tunnel, ensure a perfect flow of air around the vehicle. The key factor determining the low wind resistance is the aerodynamic efficiency of the basic body shell, including the optimised design of the front bumper, of the A-pillars and of the roof spoiler, plus numerous other detailed improvements.





The result: a high level of comfort and outstanding driving dynamics on and off the road

Even the standard version of the new M-Class offers a high level of comfort, dynamic on-road handling and outstanding off-road capabilities. For the first time, the M-Class chassis with steel suspension features selective damping. The driver is assisted by electric steering, which ensures the optimum level of steering assistance for the current driving situation. In addition to this, the SUV impresses with the smallest turning circle in its market segment.



For driving off the beaten track, the ML 350 BlueTEC 4MATIC and ML 350 4MATIC BlueEFFICIENCY models are equipped with extensive off-road features as standard, including 4MATIC permanent all-wheel drive, 4ETS electronic traction control and an off-road button which activates a special off road driving mode. Furthermore, the start-off assist system makes hill starts easier, while the Downhill Speed Regulation (DSR) automatically keeps the M Class at the speed set using the cruise control stalk.



The optional ON&OFFROAD package for the new M-Class has six driving modes for optimising driving dynamics and handling safety, as the optimum drive system control is provided for an extremely wide range of on-road and off-road operating conditions. The driver can select from one automatic mode, two special off-road modes and three on-road modes using a rotary control in the centre console. In terms of "hardware", the ON&OFFROAD package comprises an underguard, a two-stage transfer case with reduction gear, an inter-axle differential lock and enhanced AIRMATIC functionality that allows a maximum ground clearance of 285 millimetres as well as a fording depth of 600 millimetres.



Active roll stabilisation in the form of the ACTIVE CURVE SYSTEM can be optionally combined with both the AIRMATIC air suspension with Adaptive Damping System (ADS) and the ON&OFFROAD package. This system uses active anti-roll bars on the front and rear axles and compensates for the roll angle of the body through bends, increasing agility and driving pleasure in the process. The system has the additional effect of increasing handing stability and therefore safety, particularly at higher speeds. Further benefits of the ACTIVE CURVE SYSTEM include superb ride comfort both when cornering

and driving in a straight line, together with enhanced off-road abilities.



Gently does it: attention to detail ensures comfort

The new M-Class promises relaxed and, therefore, safe driving in all possible conditions. By paying close attention to detail every step of the way, the development engineers in the Mercedes Technology Center have significantly improved what they call the NVH comfort level (Noise, Vibration, Harshness). This is an important factor contributing to the general sense of wellbeing on board, whilst also playing its part in driver-fitness safety, especially on long journeys. The basis for the high level of NVH comfort is provided by the very rigid bodyshell of the M-Class. Further improvements have also been made to

the drive system and chassis. This is all topped off by aero-acoustic refinements and the intelligent use of new-style insulation.





Well thought-out: safety at its best

In line with the Mercedes-Benz brand philosophy, the new M-Class represents the embodiment of the Mercedes-Benz holistic safety concept of Real Life Safety, which is derived primarily from what happens in a real accident situation. The extremely robust occupant compartment of the M-Class, together with the front and rear deformation zones, forms an effective basis for the occupant protection system. Up to nine airbags, activated on demand in accordance with the accident type and accident severity, can reduce the loads exerted on the occupants. In addition to active safety systems such as the standard-fit Brake Assist (BAS) or the optional BAS PLUS, which can help to prevent an accident or reduce the severity of an accident, the new M-Class features further enhanced passive-safety measures to help protect pedestrians, including an Active Bonnet as standard.



Both active safety and driver-fitness safety in the new M-Class are further improved by assistance systems that will already be familiar, primarily from the S- and E-Class. The standard equipment package includes the drowsiness detection system ATTENTION ASSIST, the anticipatory safety system PRE SAFE® and a tyre pressure loss warning system, as well as adaptive brake lights and Brake Assist (BAS). Active assistance systems such as Active Lane Keeping Assist and Active Blind Spot Assist are available as additional equipment options.



Impressive credentials: the design

The new generation is instantly recognisable as an M-Class by its characteristic body design with the hallmark C-pillar shape. It combines high levels of design, appeal and ease of use to create a powerful presence. The front of the vehicle is dominated by the powerfully self-confident design of the radiator grille with its centrally positioned Mercedes star, giving it that typical M-Class look. Seen from the side, the elongated lines give formal emphasis to the on-road credentials of this vehicle, whose compact proportions are defined by a large wheelbase and short overhangs. The C-pillar that is so characteristic of this model series takes its cue from earlier generations of the M-Class and differentiates it very clearly in stylistic terms from its competitors. At the same time, the way the roof line slopes down to the rear underlines the sporty appeal of the new M-Class. No pillar is visible in the transition from the rear side window through to the rear windscreen. This, together with the similarly wrap-around effect of the two-part rear light unit with LED fibre-optic technology, and the lowered roof with its large roof spoiler, add up to an overall harmonious design. The rear bumper, which features an integrated chrome-effect load sill guard in a new "wing design", defines the characteristic appearance of the SUV's rear end. The available wheels range from light and aerodynamically optimised 43.2 cm (17-inch) wheels through to 50.8 cm (20 inch) wheels with an elegant, high-quality appeal. As an option, 53.3 cm (21 inch) AMG wheels can be fitted to emphasise the sporty look of the new M Class.



Upgrade as standard: interior with a first-class ambience

The interior design concept clearly combines an authentic SUV experience with a sense of wellbeing that is usually the reserve of top-class Mercedes-Benz saloons. While an expressive dome shape embodies the power of an SUV, the gently sloping contours of the dashboard in the front passenger area afford an outstanding sense of space, thereby highlighting the vehicle's suitability for long journeys. The spacious, bright interior offers substantially more elbow room than its predecessor (an extra 34 millimetres in the front and an extra 25 millimetres in the rear), thus enhancing spaciousness. Eye-catching features on the dashboard include a large trim element that matches the trim used for the doors and therefore creates a harmonious wrap-around effect. The seats in the new M-Class have been designed to offer high long-distance comfort and optimum lateral support. All of the key settings can be adjusted electrically. New features include rear seat backrests adjustable for angle and the through-loading feature via the armrest for transporting skis. Folding both backrests as well as the seat cushions forward creates a level load compartment with a capacity of 2010 litres up to the roof lining - a record

in this segment.



The new M-Class comes as standard with the Audio 20 CD system, which comprises a radio with twin-tuner, a colour display with a 14.7 cm screen diagonal, an MP3/WMA/AAC-compatible CD player, a USB interface with CD Cover Art display (if saved on the storage medium), an AUX-IN socket in the centre armrest and a telephone keypad. The Bluetooth interface also allows hands-free telephony and Audio Streaming for the transfer of music. One of the particularly interesting features on offer is the Becker® MAP PILOT, a fully integrated navigation module with a 2-D/3-D map display for Europe. The device is housed in a cradle in the glove compartment and is operated using the central controller for the Audio 20 CD system. The COMAND Online multimedia system with a high-resolution 17.8 cm colour display provides internet access in the M-Class for the first time. Customers can either browse



freely when the vehicle is at a standstill or use a Mercedes-Benz App with pages that load extremely quickly and are also easy to use when the vehicle is on the move. As an option, COMAND Online is available with a 6-disc DVD changer. This system's standard features include Speed Limit Assist, which recognises traffic signs and displays them in the instrument cluster.

Mercedes-Benz innovation: the NANOSLIDE

After five years and use exclusively in AMG engines, twin-wire arc spraying technology will now also be used in the series production of Mercedes-Benz diesel engines. Mercedes-Benz was the developer of what is now known as NANOSLIDE technology, in which twin-wire arc spraying is used to melt iron/carbon wires and spray them onto the cylinder surfaces of the lightweight aluminium crankcase with the help of a gasflow. Very fine finishing of the resulting nano-crystalline iron coating creates an almost mirror-like, smooth surface with fine pores, which reduces friction and wear between the piston assembly and the cylinder wall. Other advantages include lower engine weight, less fuel consumption and lower emissions. This innovation from Mercedes-Benz has been successfully used in the 6.3-litre AMG engines since 2006.



Mercedes-Benz uses the collective term BlueEFFICIENCY to describe a whole range of different measures designed to reduce fuel consumption and emissions: sophisticated aerodynamics, weight-saving measures and intelligent control of ancillary units are a few examples. With NANOSLIDE technology, the world's oldest automobile manufacturer is adding another innovation to this technology package. It sets new standards in the production of cylinder linings. These help to ensure that the piston moves up and down within the cylinder with the least possible friction losses. Comparatively heavy grey cast-iron liners with a thickness of up to five millimetres are the current state of the art.







The NANOSLIDE procedure takes a new approach. Wires of iron/carbon alloy are melted in an electric arc, and the melted material is "sprayed" onto the cylinder wall by a gasflow, where it is deposited as a layered, ultra-fine to nano-crystalline coating. The NANOSLIDE coating is then given an extremely smooth finish by a special honing process, after which it has a thickness of only 0.1 to 0.15 millimetres and has a mirror-like surface. The honing process also exposes pores in the material which are able to retain oil and thereby ensure optimal lubrication of the piston assembly. The result is not only low friction, and therefore greatly reduced mechanical friction losses compared to grey cast-iron cylinder liners (up to 50 percent), but also extremely high wear resistance.





Mercedes-Benz has plenty of experience with its in-house development of NANOSLIDE technology. In July 2005 Mercedes-AMG GmbH presented a 6.3-litre V8 which not only delivered outstanding performance figures, but was also the world's first series production engine to feature cylinder walls with a twin-wire arc sprayed coating. Since 2006 this cutting-edge cylinder coating technology has been a key component of all 6.3-litre AMG engines. The procedure has proved highly successful in more than 75,000 high-performance AMG engines to date, and meets all expectations. The specialist term "NANOSLIDE" has meanwhile become an accolade. The process involves numerous new inventions and ideas, and is protected by more than 90 patent families and over 40 patents.



In view of this positive experience, Mercedes-Benz is the world's first manufacturer to have developed this technology further for use in a V6 diesel engine.



NANOSLIDE reduces the engine weight by 4.3 kilograms compared to the preceding engine, and brings an additional fuel saving of 3 percent. The V6 diesel engine in the ML 350 BlueTEC, for example, develops an output of 190 kW (258 hp) from a displacement of 2987 cc, and generates 620 Nm of torque. Thanks to BlueTEC with AdBlue® exhaust treatment, this M-Class model already meets the emission values planned for 2014 in accordance with the Euro-6 standard, and as such is one of the world's cleanest diesel vehicles. With a combined consumption of 6.8 litres of diesel per 100 kilometres, the ML 350 BlueTEC improves on the figures of its predecessor by 2.1 litres, or 24 percent. CO2 emissions have dropped from 235 to 179 grams per kilometre, not least thanks to the new NANOSLIDE technology.

The new 2012 B-Class from Mercedes-Benz

Updated: New videos.



Substantially more agile and efficient, but as comfortable and spacious as ever – the new B-Class from Mercedes-Benz is a winner on all fronts. The vehicle's lower height and more upright seat position provide for a first impression that hints at the compact sports tourer's dynamic credentials.



With a new four-cylinder petrol engine featuring direct injection and turbocharging, a new diesel engine, a new dual clutch transmission, a new manual transmission and new assistance systems, the front-wheel-drive car also rings in a new technological era for compact cars from Mercedes-Benz. "No model change in the history of Mercedes-Benz has ever seen so many new developments introduced in one fell swoop," stresses Dr. Thomas Weber, Member of the Board of Management responsible for Group Research and Head of Development, Mercedes-Benz Cars. "Future B-Class customers will benefit from this quantum leap in terms of better fuel consumption and lower CO2 emissions combined with driving pleasure, plenty of space and the highest standard of safety that has ever been available in this class."

Mercedes-Benz Clase B 2012

The world premiere of the new B-Class (length/width/height: 4359/1786/1557 millimetres) will take place at the Frankfurt International Motor Show (13 to 25 September 2011). It will be making its way to the UK in March 2012 .



The exterior design: perfect space in a most attractive guise

The new B-Class is a typical Mercedes sports tourer, offering plenty of space combined with impressive dynamic performance as a hatchback saloon. The character lines of the exterior design indicate both of these attributes: the front and rear feature width-emphasizing design, with a wide, prominent grille and headlamps extending along the sides at the front while the rear end features a wide rear window, two-piece tail lights and a large tailgate with low loading sill.



The new sporty lines and the outstanding aerodynamics are particularly evident in the side line: the bonnet flows seamlessly into the A-pillar and the roof line descends sleekly to the striking roof spoiler. The roof features a contoured line which lends the vehicle a longer appearance. The pronounced wheel arches offset by dynamic feature lines under the beltline are a sporty interpretation of the current design line from Mercedes-Benz. The bottom edge of the body features dynamic side skirts which add a light touch to the vehicle's appearance. Refined details such as the exquisitely designed headlamps with the new spotlight element confirm the brand's unmistakable premium credentials which shine through in the compact segment, too.



Outstanding aerodynamics: astounding cd value

An outstanding drag coefficient of cd = 0.26 places the new B-Class at the forefront of its market segment. As well as the aerodynamic exterior design, numerous optimisation measures on points of detail such as the air flow around the front wheels, the underbody design and the cooling air flow are also crucial contributory factors to this excellent aerodynamic performance. Patents are pending for innovative details such as the serrated wheel arch spoiler.



New concept: lower overall height but more space inside

The new vehicle concept underscores the dynamic aspirations of the new B-Class. The most striking aspect is the reduced height: at 1557 millimetres, the new model crouches almost five centimetres lower on the road than its predecessor. The seat height in relation to the road has also been reduced (minus 86 mm) in order to facilitate getting in and out of the car easily, while maintaining a clear overview of the vehicle's contours when driving.



In response to requests from many customers, the sitting position is more upright, however. At the same time, the headroom has been further improved. With maximum headroom of 1047 mm at the front (without sliding roof), the B-Class is among the most spacious cars in its segment in this discipline, too. The ergonomically expedient more upright sitting position in combination with a lowering of the vehicle's floor at the rear leads to a segment-leading degree of legroom (976 mm) which even surpasses that of the S- and E-Class.



The B-Class is optionally available with the EASY-VARIO-PLUS system. This enables simple reorganisation of the interior so as to enable the transportation of bulky items. Features of the EASY-VARIO-PLUS system include fore/aft adjustment of the rear seats by up to 140 millimetres (thereby increasing the luggage compartment volume from 488 to 666 litres) and a front passenger seat whose backrest can be folded forward onto the seat cushion.





The interior design: superior quality in a new dimension

High-quality materials and finely structured surfaces, stylish details, precision workmanship and a new spaciousness – the interior of the B-Class defines a whole new benchmark in the compact segment.



Many features have been the reserve of higher classes of vehicle to date and embody Mercedes-Benz's special definition of quality and aesthetics. The dashboard is optionally available in ARTICO man-made leather finish and features stitching, for example. Four equipment packages (Chrome, Sports, Exclusive and Night package) enable individualisation according to personal tastes.



On the inside the large, three-dimensional trim covering the entire dashboard first strikes the eye. It is available in four variants, covering a broad spectrum from modern through sporty to classic. Common to all versions is a high-class appeal combining an attractive look and feel with easy care and durability.



The three large round vents in the middle and their uniquely designed cruciform nozzles add a sporty attribute to the interior's emotional design idiom. The display, which is available in two sizes (5.8- and 7-inch) appears to hover over the vents. With its stylish design – the trim frame with galvanised finish contrasting with the piano black of the front panel – and slender lines, the colour display (TFT) is a highly attractive feature in the cockpit.



The 3-spoke leather trimmed steering wheel, which always incorporates a silver chrome insert in the middle spoke, the instrument cluster with four analogue round dials and suspended pointers in the 6 o'clock position and the seats with contrasting stitching underscore the sporty character.



The drive: designed for maximum efficiency

The new B-Class features new petrol and diesel engines as well as new manual and automatic transmissions. All transmissions and engines have been developed in-house, with production taking place at the plants in Stuttgart-Untertürkheim and -Hedelfingen, Rastatt/Baden, Gaggenau/Baden and Kölleda/Thuringia. The simultaneous development process enabled perfect coordination of engines and transmissions, e.g. with regard to implementation of the ECO start/stop function which features as standard on all B-Class models.



Common features of the new drive systems are the use of state-of-the-art technologies for maximum efficiency, very smooth running, high tractive power right from low revs, sustainability in terms of impending emissions standards and low weight. For the purposes of transverse installation the engines, all of which are turbocharged, and the two transmissions are very compactly designed, providing the B-Class with an exemplary small turning circle for a front-wheel drive vehicle of eleven metres. The engine and transmission suspension consists of a four-point mounting system comprising engine mount, transmission mount and two self-aligning supports. This suspension system has been designed specifically to meet the requirements of the high-torque engines with regard to minimum noise levels. The hydraulic damping integrated in the transmission mount is a key contributory factor to the exceptionally high ride comfort.



The new four-cylinder petrol engines (internal designation M270) mark the launch of a completely new engine series. The combustion process is based on the third-generation Mercedes-Benz direct injection system which was introduced last year with the BlueDIRECT V6 and V8 engines. Its use in the B-Class marks this technology's debut in the compact segment. The new four-cylinder engines have been designed for both transverse and longitudinal installation. In the new B-Class they are initially available with a displacement of 1.6 litres, as the B 180 rated at 122 hp and the B 200 with an output of 156 hp. Their maximum torque of 200 and 250 Nm respectively is available from an engine speed of 1250 rpm.



The new four-cylinder diesel engine is a further development of the OM651 deployed in the C- to the S-Class, a common rail direct-injection engine of the third generation. With its displacement scaled down to 1.8 litres and numerous optimised points of detail, this is the first time that the compression-ignition engine has been mounted transversely in a Mercedes-Benz car. The B 180 CDI generates 109 hp of power, while the B 200 CDI has an output of 136 hp. The maximum torque stands at 250 Nm from 1400 rpm for the 80 kW variant and 300 Nm from 1600 rpm for the 100 kW variant.



Another Mercedes-Benz premiere is the new 7G-DCT dual clutch transmission in the B-Class. This transmission is extremely compact, extremely variable with regard to adaptation of the engine speed thanks to seven gears, features an electric oil pump for start/stop capability, shifts gear without any interruptions in tractive power and combines the comfort of an automatic with the efficiency of a manual transmission.



The new 6-speed manual transmission designed along similarly compact lines as a three-shaft transmission is a close relative of the DCT. Extremely easy gear shifting, low shift forces, low internal friction and a low weight are among its most important characteristics.



The chassis and suspension: refined sportiness now for the sports tourer, too

"Fantastically agile" is the assessment of all test drivers who have put the new B-Class through its paces to date. Three factors are instrumental to the substantially enhanced dynamic performance in comparison to its predecessor, which does not come at the cost of any compromises on comfort: the lowered centre of gravity, the new four-link rear axle and the upgraded ESP®Electronic Stability Programme. A sports suspension is optionally available for further enhanced agility. The centre of gravity has been lowered by a further 20 mm and the suspension additionally features sports dampers with amplitude-selective damping and a Direct-Steer system will be standard on the Sport model line.



Steering: mechanical with electric assistance

The electromechanical steering of the B-Class has been redesigned. The electric motor of the servo assistance system is now located directly on the steering gear as a dual pinion EPS system, thereby optimising the package as a whole. The steering ratio becomes noticeably more direct at greater steering angles, enhancing the vehicle's handling and agility substantially. The electromechanical steering system makes an important contribution to the vehicle's overall efficiency, as the steering assist function only requires energy when steering actually takes place.



New assistance and braking system reduces the risk of rear-end collisions

As a world first in the compact segment, the B-Class features a radar-based collision warning system with adaptive Brake Assist as standard, which lowers the risk of rear-end collisions. The COLLISION PREVENTION ASSIST system outputs a visual and acoustic warning to alert a possibly distracted driver to identified obstacles, and prepares Brake Assist for the most precise possible braking response. This is initiated as soon as the driver emphatically operates the brake pedal.



In contrast to systems currently on the market in the compact class, the new COLLISION PREVENTION ASSIST brake assist feature is not merely a system intended to minimise minor damage in urban traffic. Rather, this innovative solution is aimed at protecting motorists from typical rear-end collisions in dangerous traffic situations. Mercedes-Benz expects the new safety system to have a significant positive effect on accident statistics.



The area of safety also encompasses an array of other assistance systems which have been adopted into the B-Class from the larger model series. These include:



- Adaptive Headlamp Assist

- Blind Spot Assist and Lane Keeping Assist

- ATTENTION ASSIST (standard)

- Speed Limit Assist (speed limit sign recognition)

- Active Parking Assist(standard)

- Brake HOLD function (standard with 7G-DCT)

- Hill Hold function (standard)

- LINGUATRONIC

- Reversing camera

- DISTRONIC PLUS





Premiere in the compact class: PRE-SAFE® available for the first time

The PRE-SAFE® preventive occupant protection system which features in the B-Class is available for the first time in this vehicle category. This represents a further step in the ongoing implementation 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.



he scope of restraint facilities takes special account of the B-Class' 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. Integrated child seats and automatic child seat recognition are available as in the predecessor. Driver and co-driver are provided with new pelvis bags which are able to cover the pelvis and the entire upper part of the body. For head protection, a windowbag is fitted as standard.



COMAND Online multimedia system with internet access

Internet access, the convenient LINGUATRONIC voice control system, two navigation solutions tailored to different budgets, connection for mobile audio devices and an intuitive operating concept – the information and communication systems in the B-Class offers excellent user-friendliness and a superior level of functionality which has been the reserve of higher categories of vehicle to date. It is the new multimedia generation from Mercedes-Benz which delivers these standards. The operating concept featuring the turn/push control in front of the armrest and the control knob on the head unit is also familiar from other Mercedes model series.



The COMAND Online multimedia system offers internet access. Customers can either surf the web as they wish while the car is stationary or call up a Mercedes-Benz app whose particularly fast page loading and simple operation make it suitable for use while driving. Integrated apps include Google™ Local Search and Weather, and the facility for downloading a route which has previously been configured on a PC using Google Maps and transmitted to the car.



All set for the future: modular "Energy Space" concept

The modular "Energy Space" concept means that the new B-Class is already designed to accommodate versions with an alternative drive: appropriate interfaces in the body shell enable the main floor panel to be modified and a step to be produced for the versions with alternative drive. An underfloor compartment covering part of the area under the rear bench seat offers space for alternative energy accumulators.

New Mercede-Benz SLK 55 AMG and 250 CDI

The Mercedes-Benz SLK 55 AMG is the most powerful SLK of all time. Its newly developed AMG 5.5-litre V8 engine featuring cylinder shut-off combines the ultimate in performance with the best possible fuel consumption. With a peak output of 422 hp and maximum torque of 540 Nm, the SLK 55 AMG outperforms all of its direct competitors. Its fuel consumption of 33.6 mpg on the combined cycle and CO2 emissions of 195 grams per kilometre are around a 30 percent improvement of that of its predecessor. High levels of driving dynamics are ensured thanks to the AMG sports suspension with Direct-Steer system, Torque Vectoring Brakes and 3-stage ESP®, as well as the AMG high-performance braking system.



Forming part of the third-generation of the SLK launched in March, the new top-of-the range AMG model already demonstrates its individuality even at first glance: distinctive AMG light-alloy wheels, specific AMG bodystyling with AMG spoiler lip and two chrome-plated twin tailpipes at the rear complement the classic roadster proportions, while adding a markedly athletic touch. The expressive design of the SLK 55 AMG is both eye-catching and unmistakable.

Mercedes-Benz SLK 55 AMG

The SLK 55 AMG is the perfect embodiment of the new AMG brand claim of "Driving Performance": in the compact high-performance roadster segment there is nothing to compare to its combination of tangible driving dynamics, superior sportiness, unique high-technology and low fuel consumption. The SLK 55 AMG accelerates from 0-62 mph in 4.6 seconds, and reaches a top speed of 155 mph (electronically limited).



The world's most fuel-efficient V8 engine combines the lowest consumption figures with the superior power delivery and the typical sound experience which only a large-displacement eight-cylinder engine can provide.



In line with its "AMG Performance 2015" strategy, with the new V8 unit Mercedes-AMG is meeting its promise to continue to reduce both the fuel consumption and emissions of new models over the next few years – while reaching new heights with the central brand claim of "Driving Performance". At the same time, AMG is also demonstrating its social responsibility with the M152.



New naturally aspirated eight-cylinder closely related to the V8 biturbo

The new M152 is based on the AMG M157 5.5-litre V8 biturbo engine presented in 2010, which powers the E 63 AMG, CLS 63 AMG, S 63 AMG and CL 63 AMG. Numerous design features are identical, such as the displacement, bore/stroke, distance between cylinders, start/stop system and direct petrol injection technology. Distinguishing features versus the M157 include the new intake air ducting, new cylinder heads, the modified valve drive, an adapted oil supply system and an optimised crankcase.



Exclusive combination of advanced technologies

The high-tech M152 powerpack enthrals with a combination of advanced technologies which is unequalled anywhere in the world. No other petrol engine features direct injection at a pressure of 200 bar, spray-guided combustion and piezo injectors, all in conjunction with map-controlled cylinder shut-off, an all-aluminium crankcase with "spectacle" honing, four-valve technology with continuous camshaft adjustment, a high compression ratio of 12.6 : 1, a start/stop system and generator management – while revving to a maximum speed of over 7000 rpm. All of these measures lead to high thermodynamic efficiency, which is a precondition for high fuel efficiency and low exhaust emissions. Moreover, deciding in favour of a large-displacement, naturally-aspirated eight-cylinder unit with cylinder shut-off resolves the conflict of aims between high output/torque delivery and improved fuel consumption figures.



AMG Cylinder Management

It is the AMG Cylinder Management cylinder shut-off system in particular – completely newly developed by Mercedes-AMG - that significantly improves efficiency: cylinders two, three, five and eight are cut off under partial load, which lowers fuel consumption considerably. In similar form this technology is also used in the approx. 750 hp V8 engines used in Formula 1. As efficiency also plays a major role at the pinnacle of motor racing, two or four of the eight cylinders are cut off e.g. when cornering at slow speed, in the Safety Car phases or for pit stops. With a fuel consumption of 33.6 mpg and CO2 emissions of 195 grams per kilometre (NEDC combined), the naturally-aspirated AMG V8 engine comes in at or below the level of its competitors, however these are unable to match either the output or torque of the SLK 55 AMG – and above all, they do not use large-displacement eight-cylinder engines.



The cylinder shut-off function is available over a wide engine speed range from 800 to 3600 rpm if the driver has selected transmission mode "C" – Controlled Efficiency. The AMG main menu in the instrument cluster informs the driver whether cylinder shut-off is active, and whether the engine is currently running in four or eight-cylinder mode. No less than 230 Nm of torque is still available in four-cylinder mode – enough power to ensure plenty of acceleration in most driving situations. As soon as the driver has a need for more power and leaves the partial load range, cylinders two, three, five and eight are activated. The switch from four to eight-cylinder operation

is immediate and imperceptible, leading to no loss of occupant comfort whatsoever. At an engine speed of 3600 rpm the activation process takes

no more than 30 milliseconds.



Valves closed, fuel delivery and ignition deactivated

This is made possible by intelligent interaction within the highly effective engine management system, with 16 hydraulically compensating elements and a complex oil supply system in the cylinder head. The compensating elements are integrated into the cylinder head, and keep the intake and exhaust valves of cylinders two, three, five and eight closed when cylinder shut-off is active. At the same time their fuel supply and ignition are deactivated. This not only enables the load-change losses of the four deactivated cylinders to be reduced, but also increases the efficiency of the four remaining cylinders. This is because the operating point is transferred to the higher load range. The compensating elements are compact and lightweight, allowing taut valve train operation and engine speeds up to 7,200 rpm.



All-aluminium crankcase with Silitec cylinder liners

The crankcase of the new AMG 5.5-litre V8 engine features a diecast all-aluminium construction. The low (dry) engine weight of just 187 kilograms is the result of uncompromising lightweight construction methods. The bearing covers for the main crankshaft bearings are of grey cast iron, and are bolted

to the crankcase, as well as on the sides, for high rigidity.



The piston rings are carbon-coated to minimise internal friction and optimise the wearing characteristics. Cast-in Silitec cylinder liners ensure low friction for the eight pistons. So-called "spectacle" honing is another measure to reduce friction and therefore fuel consumption: in this sophisticated and complex process, the cylinder liners receive their mechanical surface treatment when already bolted in place. As honing would no longer be possible with the cylinder head installed, a jig resembling spectacles is bolted to the crankcase. The cylinder liners distort as if the cylinder head were in place, and are only then given their mechanical surface treatment. As a result, any static distortion of the cylinder liners caused by tightening the cylinder head bolts can be completely eliminated.



Other measures to optimise efficiency:



- weight-optimised cast aluminium pistons with special piston skirt coating

- special ventilation holes in the crankcase

- oil pump with electrically controlled pressure stage

- separate oil pump for cylinder shut-off as a controllable, low-friction vane cell pump

- engine cooling on the particularly efficient cross-flow principle

- electronically controlled fuel pressure, fully variable and demand-related between 100 and 200 bar



The forged crankshaft of high-grade 38MnS6BY steel alloy rotates in five main bearings, has eight counterweights and has been optimised with respect to torsional rigidity, inertia, low rotating masses and a long operating life. A two-mass viscous damper mounted at the front reliably eliminates vibrations. Each connecting rod journal on the crankshaft carries two forged, cracked connecting rods.



Four-valve technology with variable camshaft adjustment

Perfect charging of the combustion chambers is ensured by large intake and exhaust valves, of which there are four per cylinder. The exhaust valves, which are subject to high thermal loads, are hollow and sodium-cooled. Four overhead camshafts operate the 32 valves via low-maintenance, low-friction cam followers. The infinitely variable camshaft adjustment within a range of 40 degrees on the intake and exhaust sides depends on the engine load and engine speed, leading to high output and torque values. This also results in consistent idling at a low speed. Depending on the engine speed, valve overlap can be varied for the best possible fuel/air supply to the combustion chambers and efficient removal of the exhaust gases. The variable camshaft adjustment is carried out hydraulically via four pivoting actuators. These are electromagnetically actuated and controlled by the engine control unit. The camshafts are driven by three high-performance silent chains, which have considerable advantages in terms of noise comfort compared with cylinder roller chains.



Controlled Efficiency start/stop function as standard

The Controlled Efficiency start/stop function further contributes to the low fuel consumption. This system is standard equipment on the SLK 55 AMG, and active in the fuel economy transmission mode "C". Once the driver comes to a halt e.g. at a red traffic light, the V8 engine is automatically switched off. Once the brake pedal is released or the accelerator is depressed, the engine is immediately restarted and the car is able to move off quickly. Intelligent technology guarantees a comfortable and immediate starting procedure: a crankshaft sensor which recognises the direction of rotation registers the resting position of all eight pistons. For an automatic engine start, the cylinder with the most favourable piston position receives an injection of fuel into its combustion chamber. The precise piezo-electric injectors greatly assist this process, as they make particularly fast starts possible. The M152 always starts in eight-cylinder operation.



A framed "ECO" symbol in the AMG main menu shows the driver that the Controlled Efficiency start/stop function is active. When cylinder shut-off is active, the driver is informed by the symbol "ECO4", while "ECO8" stands for eight-cylinder operation. In the two more performance-oriented driving modes "S" (Sport) and "M" (Manual), the start/stop function is always deactivated. If required, the driver can also switch it off while in "C" mode as well. In this case neither a "start/stop" nor an "ECO" symbol appears.



Generator management helps to save fuel

A generator management system makes a further contribution to fuel economy: whenever the V8 engine is on the overrun or when braking, kinetic energy is used to charge the battery rather than being wasted as heat in the usual way. In all other operating modes a combination of onboard network and generator management enables the generator to be kept at a low voltage. This reduces the load on the engine and enhances fuel efficiency in city traffic with its frequent overrun and braking phases.



New AMG sports exhaust system with integrated exhaust flaps

For the first time AMG is using a sports exhaust system featuring an exhaust flap on each side. This technology resolves the conflict of aims between an emotional sound when driving in a sporty manner and a more discreet engine note in the partial load range. The main focus of the sound design was on achieving a perfect synthesis of perceptible dynamism and the long-distance comfort that is a hallmark of Mercedes.



Each of the two rear silencers has a flap which is variably activated on a logic-controlled basis depending on the driver's power requirement and the engine speed. At low loads and engine speeds below 2000 rpm the flaps remain closed. This causes the exhaust gases to cover a longer distance and flow through an additional damping element, so that the engine sound is pleasantly subdued and irritating frequencies are effectively suppressed – resulting in a harmonious sound impression especially in four-cylinder operation when cylinder shut-off is active.



When the driver accelerates, the flaps open at an angle of 15, then 30 and up to 50 degrees so that some of the exhaust gases cover the longer, acoustically dampened distance and some the shorter distance. This produces a sonorous engine note. Under full load at higher engine speeds in eight-cylinder mode, both flaps are fully opened so that the occupants are able to enjoy the decidedly muscular sound typical of an AMG V8. In short, they are left in no doubt about the performance potential of the 422 hp naturally aspirated AMG eight-cylinder engine.



The two-pipe AMG sports exhaust system with two chromed twin tailpipes has a pipe diameter of 65 millimetres from the manifolds to the pre-silencer. The diameter is reduced to 60 millimetres from the pre-silencer to the rear silencers.



Effective emissions technology with new catalytic converter boxes

Low exhaust emissions, compliant with country-specific standards and a characteristic engine sound – the requirements for the exhaust system of the new, naturally aspirated AMG 5.5-litre V8 engine were complex. The SLK 55 AMG complies with the current Euro-5 emission standard, as well as meeting all the requirements of the US market (LEV-III standard, On-Board Diagnosis II).



Air gap-insulated manifolds ensure a rapid catalytic converter response. For efficiency and to save space, this concept has a tandem catalytic converter housing on each side of the vehicle: adjacent to the firewall, two thin-walled ceramic substrates are grouped into each housing. This solution makes the previous, additional underbody catalytic converters unnecessary. The two ceramic substrates differ to ensure rapid and efficient emissions control: the front one is coated with palladium, while the rear one has a bimetal coating of palladium and rhodium. One lambda sensor per row of cylinders is located in front of each catalytic converter housing, and there is a lambda diagnostic sensor between each of the two thin-walled substrates.



Highly variable: the AMG SPEEDSHIFT PLUS 7G-TRONIC

Power is transferred to the rear wheels by means of the AMG SPEEDSHIFT PLUS 7G-TRONIC automatic transmission which features three transmission modes: "Controlled Efficiency" (C), Sport (S) and Manual (M). The automatic double-declutching function when downshifting as well as the brief, precisely defined interruption of ignition and injection when upshifting under full load shorten shifting times and increase emotional appeal when adopting a sporty driving style. A double turbine torsional damper with centrifugal pendulum which adapts to engine speed helps to minimise vibrations in four-cylinder operation and enhances the impression of comfort experienced by the vehicle occupants.



Perfect combination: highly dynamic driving style and comfortable cruising

The AMG sports suspension with Torque Vectoring Brakes and AMG Direct-Steer system provides both impressive lateral dynamics as well as agile handling. Looking for a highly dynamic driving style or comfortable cruising? The new SLK 55 AMG is able to offer both. Independent suspension struts with stiffer spring/damper tuning, torque strut bearings on the front axle featuring higher rigidity, stiffer stabilisers all round as well as a more negative camber on the rear axle result in high cornering speeds and a low body roll in fast S-shaped bends.



In critical cornering conditions, the Torque Vectoring Brakes produce a defined rotational movement of the vehicle about the vertical axis in fractions of seconds, through selective brake actuation at the rear wheel on the inside of the bend. This results in the SLK 55 AMG steering into the bend precisely and under full control, without any compromises where dynamism is concerned. Complementing this feature perfectly is the AMG Direct-Steer system: it enhances handling and agility compared with the standard steering, whilst also reducing the amount of physical effort required when parking. A new power steering pump helps to improve fuel consumption. The reason behind this: the power assistance for the steering only requires energy when the driver is actually steering. In addition, the AMG Direct-Steer system has a parameter function adapted to match the AMG sports suspension. This results in optimum response from the central position, outstanding road feel and dynamic handling in all driving situations.



The AMG-exclusive 3-stage ESP® gives individual control strategies at the touch of a button: the ESP® button in the centre console allows the driver to choose between "ESP ON", "SPORT Handling Mode" and "ESP OFF". The AMG high-performance brake system has internally ventilated and perforated brake discs on all wheels, measuring 360 x 36 mm at the front and 330 x 22 mm at the rear. The system is characterised by outstanding responsiveness, short stopping distances and excellent fatigue strength.



Optional AMG Handling package for even greater driving dynamics

The optionally available AMG Handling package enhances the vehicle's sportiness even further. It comprises an AMG Performance suspension with stiffer tuning, an AMG rear axle differential lock, composite brake discs at the front and a three-spoke AMG Performance steering wheel finished in nappa leather with Alcantara® inserts in the grip areas.



Unmistakable: uniquely styled design and appointments

Classic roadster proportions with typical AMG design characteristics as well as a hint of the SLS AMG – these are the striking visual highlights of the new SLK 55 AMG. The AMG designers have complemented the exciting basic forms of the long bonnet, the greenhouse positioned well to the rear and crisp rear section with typical AMG styling at the front, sides and rear. The new AMG front apron has large air inlets and AMG-specific LED daytime driving lights. Inspired by the SLS AMG super sports car, the wide radiator grille features a large, centrally-positioned Mercedes star. In the case of the SLK 55 AMG, the slats in the radiator grille and the lower cross strut on the front apron are painted in a high-gloss black finish. Darkened clear-lens headlamps and darkened bicolour tail lamps also come as standard exclusively on the top-of-the-range V8 model. The Intelligent Light System (ILS) is also available as an optional extra.



The vent grilles with chrome-plated fins in the front wings are not only reminiscent of the SLS AMG, but also evoke memories of the famous Mercedes-Benz 300 SL Roadster from the 1950s. The "V8 AMG" lettering beneath the grilles points to the top-of-the-range eight-cylinder model from the SLK model series. AMG-specific, distinctively styled side sill panels continue the design of the front apron through to the new rear apron. With its own unique shape, black diffuser insert with three fins as well as the two chrome-plated twin tailpipes of the AMG sports exhaust system, it gives a distinctive finishing touch to the vehicle. The spoiler lip on the boot lid, painted in the vehicle body colour, reduces lift at the rear axle and thereby increases driving stability at high speeds.



Inspired by the SLS AMG: high-quality, stylish interior

Functional, stylish, high-quality: the interior design of the SLK 55 AMG is also reminiscent of its bigger brother, the SLS AMG Roadster. Associations with the super sports car are evoked courtesy of the four air vents in the style of jet engines, as well as the centre console finished in brushed aluminium. An optional addition to the centre of the dashboard is an AMG-specific analogue watch featuring an IWC design. The AMG Performance steering wheel, with its flattened top and bottom sections, also boasts metal trim, aluminium shift paddles and grip areas finished in perforated leather. The clearly-arranged AMG instrument cluster is positioned perfectly in the driver's field of vision and features four circular instruments, distinctive dials and the AMG main menu. The switch for the transmission modes C, S and M is also located in the centre console.



The AMG sports seats with individual seat upholstery layout and optimised lateral support come as standard with the upholstery combination ARTICO man-made leather/black fabric and high-quality AMG badges in the backrests. Nappa leather and Exclusive nappa leather are both available as optional extras. As in the previous model, the AIRSCARF neck-level heating system is also available as an optional extra. This creates a flow of warm air around the neck and shoulder areas of the occupants from a vent in the front of each head restraint.



Magical: the panoramic vario-roof with MAGIC SKY CONTROL

The standard vario-roof opens and closes in less than 20 seconds, transforming the open-top Roadster into a closed-top Coupé with rigid roof at the touch of a button. Alternatively, a panoramic vario-roof in tinted polycarbonate can also be chosen. The third variant is a world premiere – the panoramic vario-roof with MAGIC SKY CONTROL. This glass roof switches to light or dark as required at the press of a button. When light it is virtually transparent, offering an open-air experience even in cold weather. In its dark state the roof provides welcome shade and prevents the interior from heating up when the sun’s rays are very intense. In other words: a feel-good atmosphere at the touch of a button



The frames of the three roof variants are made of magnesium. This makes each roof around six kilograms lighter than in the previous model, giving the car a lower centre of gravity – which benefits its agility. A comfortable alternative to the standard draught-stop is the new AIRGUIDE pivoting draught-stop. It consists of pivoting transparent plastic layers which are attached to the reverse of the roll-over bars. This is the world's first draught-stop system that enables different comfort levels to be selected for two occupants, as the driver and passenger can individually pivot the units to the centre of the vehicle in a flash, thus taming turbulent air flow from the rear. The advantage: no installation or removal effort required.



More individuality: designo and the AMG Performance Studio

Designed to meet the needs of those with even more individual tastes are the optional appointments "designo leather" and "designo Exclusive leather", offering eleven single-tone and ten two-tone upholstery variants. With designo the AMG sports seats feature a specific design which distinguishes them from the standard sports seats. Available matching elements include "AMG carbon-fibre trim" and "designo trim in black piano lacquer" for the centre console. The designo Alcantara® windscreen frame, seat belts in silver or red and also five attractive paint finishes – including two matt paint finishes – round off the stylish appearance perfectly.



Other attractive optional appointments are also exclusively available for the SLK 55 AMG from the AMG Performance Studio:



- AMGmulti-spoke light-alloy wheels, painted in titanium grey with a

- high-gloss finish, with 235/40 R 18 (front) and 255/35 R 18 (rear) tyres

- AMGmulti-spoke light-alloy wheels, painted in matt black with a

- high-gloss finish on the rim flange, with 235/40 R 18 (front) and

- 255/35 R 18 (rear) tyres

- AMGHandling package (AMG Performance suspension, AMG rear axle differential lock, composite brake discs on the front axle, AMG Performance steering wheel with Alcantara® inserts in the grip areas).

- AMGdoor sill panels, illuminated in white using LED technology

- AMGfloor mats

- AMGPerformance steering wheel with Alcantara® inserts in the grip areas



Exceptional position: modern assistance systems on board

The SLK 55 AMG sets new standards when it comes to safety: a whole host of the latest assistance systems support the driver and have helped to secure the new AMG Roadster's exceptional position in its segment. Standard equipment includes new, fibre-reinforced roll-over bar, two-stage driver and front passenger airbags, headbags, thorax airbags, seat belt tensioner with degressive belt force limiters, NECK-PRO crash-active head restraints, automatic child seat recognition, three-stage ESP®and also ATTENTION ASSIST drowsiness detection.



Further assistance systems are available on request:

- DISTRONIC PLUS: this proximity control system automatically maintains a set distance from the vehicle ahead, braking the SLK 55 AMG to a standstill if necessary and also accelerating the Roadster again.

- The Intelligent Light System (ILS) provides five lighting functions (cornering light function, country mode, motorway mode, active light function and enhanced fog lamps), which are activated depending on the driving conditions

- Speed Limit Assist is able to detect speed limit signs using a camera on

- the inside of the windscreen, and indicate the detected speed limit in the instrument cluster or central display.

- The anticipatory and reversible PRE-SAFE® occupant protection system is able to activate protective measures for the car's passengers as a precaution. The aim is to prepare the occupants and the vehicle for an imminent collision so that the seat belts and airbags are able to fulfil their protective function to the full during an impact.

- The PRE-SAFE® Brake detects the acute danger of a rear-end collision and prepares for autonomous braking. The system is active at speeds of between 30 and 200 km/h when moving vehicles are detected in front

- of the car.



Three generations: the SLK made by AMG

The new SLK 55 AMG is already the third generation of the exclusively dynamic Roadster model made by AMG. It all started in 2001 with the SLK 32 AMG. Its AMG V6 supercharged engine with a displacement of 3.2 litres produced 354 hp and maximum torque 450 Nm – as such, the SLK 32 AMG

was the most powerful vehicle among the competition.



At the end of 2004 this was followed by the SLK 55 AMG. With its AMG 5.5-litre V8 engine, which developed 360 hp and 510 Nm of torque, it also assumed the leading position in its segment. No other vehicle in this class offers a large-displacement eight-cylinder engine – and Mercedes-AMG has remained consistently true to this philosophy with the successor model. The new SLK 55 AMG will launch in the UK in January 2012, specification and pricing are still to be confirmed.





THE NEW SLK 250 CDI - SPORTS CAR PERFORMANCE WITH THE FUEL ECONOMY OF A SUB-COMPACT

For the first time, Mercedes-Benz is offering the sporty SLK Roadster with a diesel engine. The 204 hp four-cylinder power unit puts the two-seater at the top of its class in numerous respects.



With a fuel consumption of 56.5 mpg on the combined cycle, it is the most economical roadster in its segment. Thanks to its enormous torque of 500 newton metres it accelerates from 0-62 mph in 6.7 seconds. The result is superior driving enjoyment both on winding country roads and on long motorway stretches. Like the other models in the latest SLK family, which launched in June 2011, it combines lively sportiness with high-quality appointments and excellent comfort.



Diesel drive and roadster excitement do not go together – or so a common misconception would have it. Mercedes-Benz impressively demonstrates the contrary with the new SLK 250 CDI. Its four-cylinder diesel engine with a displacement of 2143 cc generates an output of 204 hp and 500 newton metres of torque – as much as a petrol engine with twice the displacement would normally generate. This makes the new SLK 250 CDI the most powerful diesel model in its class, and gives the roadster the potential for extremely sporty performance.



Equipped with the standard 7G-TRONIC PLUS automatic transmission (a six-speed manual transmission will follow in the second quarter of next year), the diesel SLK sprints from 0-62 mph in 6.7 seconds and achieves a top speed of 150 mph.





Apart from this, the SLK 250 CDI is the most economical and therefore environmentally compatible roadster in its segment. It returns 56.5 mpg and emits CO2 emissions of just 132 g/km. In other words, the diesel SLK combines thoroughbred sports car performance with the fuel economy of a sub-compact. This guarantees great driving pleasure with great fuel efficiency.



The diesel engine achieves its exemplary output, torque, fuel consumption and emissions figures, as well as its highly impressive smoothness for a diesel unit, thanks to an extensive package of innovative technologies. These include fourth-generation common-rail injection with a rail pressure of 2000 bar and precise injection timing, as well as two-stage turbocharging. Like all SLK models, the SLK 250 CDI also features a start/stop system as standard.



The frugal fuel consumption makes the SLK 250 CDI a car with superior long-distance qualities. Using the European motorways, it is for example quite possible to drive from the North Sea to a beach on the Mediterranean non-stop. Very comfortable sports seats, a comfortable suspension setup and the largest luggage capacity in this segment also do their bit to create the right conditions.





As it shares the same genes with the other members of the successful SLK family, the SLK 250 CDI combines lightfooted sportiness with stylish comfort, a striking sports car design and absolute day-to-day suitability, while delivering top performance with exemplary ecology. This means that the diesel version too provides open-top driving enjoyment at an extraordinarily high level.



The SLK 250 CDI is likewise available with a choice of three versions of the famous vario-roof – one of them the panoramic vario-roof with MAGIC SKY CONTROL. This glass roof can be changed from dark to transparent at the touch of a button. There are also three suspension versions available: a conventional steel suspension, a sports suspension with a stiffer spring and damper setup or a suspension with an electronically controlled, fully automatic damping system. The latter is part of the Dynamic Handling package, which also includes the Direct-Steer system and the Torque Vectoring Brake developed by Mercedes-Benz for particularly agile and predictable handling characteristics.



Externally the new SLK 250 CDI is no different in appearance from the petrol models. It even retains the twin exhaust system, and therefore has the same exciting look for which all the SLK models are known.



The new SLK 250 CDI will go on sale in the UK early in 2012, pricing is still to be confirmed.

Smart ebike to go on sale in 2012: Urban electric mobility from Smart

The smart ebike is going into series production. With this step smart as a pioneer of local emission-free electric mobility is expanding its e-product portfolio. A near-series version of the smart ebike will be on display at the "Eurobike" show in Friedrichshafen (31 August - 3 September 2011) and at the Frankfurt Motor Show (13 - 25 September 2011). The smart ebike is being developed and built in cooperation with the renowned e-bike manufacturer GRACE, based near Berlin. The ebike will be launched in the first half of 2012 and will initially be marketed by dealers in Europe and North America.



smart CEO Dr. Annette Winkler says "The smart ebike is a true smart – but on two wheels. It's not just an extremely well designed bicycle that is sure to draw admiring glances in the city – it's also really practical and child's play to ride. Anyone can zip through town on it with or without exerting themselves – depending on their fitness level and as the mood takes them. And it's even easier to find a parking space than with the smart fortwo."







Power-assisted mobility on two wheels is in. According to the association of the two-wheeler industry (ZIV) sales figures in Germany alone rose from 70,000 in 2007 to 200,000 in 2010. In 2018 the ZIV predicts that e-bikes will make up 15 percent of all bicycle sales in Germany. And in Europe as a whole sales are booming even more. In 2007 approximately 200,000 people opted for an electric bicycle and according to the ZIV by 2009 this figure had already risen to 500,000. And in 2010 around 700,000 e-bikes were sold throughout Europe – a plus of 40 percent compared with the previous year.

With an unconventional design in line with the style of the brand, functions appropriate for city use and high technology standards that are demonstrated by the extremely efficient and high-performance drive package among other features, the smart ebike has an exceptional position.



Annette Winkler says "We at smart have been gathering experience of electric drives and the mobility needs of city dwellers around the world for years. The smart ebike is the logical product of this experience and complements the smart fortwo extremely well. We listened to what people wanted from a perfect city bike and then came up with some clever solutions such as the integrated USB port for smartphones or energy recuperation during braking. The smart ebike is a real high-tech product and its price of less than €2,900 in Germany will make it a very attractive option."





Distinctive design with the characteristic smart signature

The smart ebike created by the smart designers boasts a clear design idiom and an independent appearance. It clearly breaks with conventional bicycle design with attractive integration of the components of the electric drive. The main components such as the frame, battery housing, handlebars, lights or mudguards have been designed and developed specifically for smart.



The two-material and two-colour concept is also typically smart. The plastic battery housing forms a striking contrast to the aluminium frame of the smart ebike and the dynamic look is rounded off by 26 inch wheels. The headlamp and rear light feature LED technology.



Efficient and powerful electric drive

smart's high technological standards are manifested in the extremely efficient and high-performance drive package. As a pedelec(Pedal Electric Cycle) the smart ebike is strictly speaking a hybrid vehicle: the electric motor – a maintenance-free and brushless rear-wheel hub motor from BionX – switches on as soon as the rider starts pedalling as with a normal bicycle.Muscle power is transmitted to the rear wheel via a durable and quiet belt drive. An integrated three-speed gear hub provides for comfortable gear changing.



The strengths of the ebike include its agile performance: the rider of the smart ebike decides how much power he wants the 250 watt electric motor to deliver to support his muscle power by pressing a button on the handlebar. There is a choice of four power levels with the fourth and highest level providing maximum pushing power. Depending on the power level selected and the manner of cycling a battery charge can last for more than 100 kilometres.



With more than 400 Wh the lithium-ion battery is one of the most powerful batteries in the competitive environment. It has been attractively integrated on the smart ebike and is housed on the lower bar in the frame triangle under a plastic housing. The portable battery can be charged either at a normal socket or whilst riding with the latter offering advantages in terms of cost and the environment. The wheel hub motor becomes as a generator when the rider brakes. The braking energy is recuperated, i.e. it is converted into electrical energy and stored in the smart ebike's lithium-ion battery.



High-quality components guarantee dynamic, safe and fun cycling. For example, MT4 disc brakes from Magura are fitted at the front and rear. The fully integrated brakes interrupt the power supply to the motor during braking, stop its propulsion power and reverse the polarity so that it becomes a generator for recuperation of braking energy.



The smart ebike also features state-of-the-art infotainment: a USB interface is a standard feature and enables various mobile end devices to be connected with the help of a versatile cradle. There are even plans to develop a special app for the iPhone which would allow smart ebike riders to use their iPhone as an information centre, for example to call up information on the charging status and range.





Simple operation and highly functional

Straightforward operation, a low weight, excellent ergonomics and a practical stowage space concept all contribute to making the smart ebike fun to ride. As a pedelec the smart ebike combines the comfort of a motorised two-wheeler with the easy handling of a bicycle. In EU countries neither a driving licence nor a licence plate are required as the electric motor of a pedelec only assists propulsion up to a speed of 25 km/h. This is also a clear advantage in terms of safety.



Charge management is just as simple: the battery can either be charged right on the ebike or it can be easily removed for charging at an indoor socket and then reinserted.



Thanks to different variants for the handlebars and seatpost the smart ebike can be adjusted to fit riders of different heights – a simple and efficient solution that is typically smart. A rear rack and further stowage options will be offered, for example, trendy and highly functional bags in the smart design tailored to the rack system are currently being developed.



Expert partner from the two-wheeler industry smart is developing and producing the new smart ebike in close cooperation with the e-bike manufacturer GRACE based near Berlin. Three years ago marketing specialist Michael Hecken and mountain bike legend Karl-Heinz Nicolai got together to produce particularly innovative and high quality e-bikes. The smart ebike is therefore "Made in Germany" and will be produced in premium quality.

Mecedes-Benz Actros 1860 VS GM Class 66 in a contest from Daventry to Coatbridge

Commercial Motor, the UK’s largest weekly road transport magazine, teamed up with Railways Illustrated to stage a “head to head” challenge pitting a truck against a freight train. The purpose: to prove in real-life operating conditions, which mode of transport could deliver the goods to their destination in the quickest time.



Mercedes-BenzUKlaid on a flagship Euro 5 Actros 1860 MegaSpace 4x2 tractor unit, which was up against the latest GM Class 66 Train. Simultaneously departing from DIRFT (Daventry International Rail Freight Terminal) these two giants of the transport world demonstrated their individual strengths on the route north to Coatbridge Container Terminal, Glasgow.



With the track clear of the “wrong type of leaves” and traffic running smoothly on the M6, the first gauge of progress came some 13 miles in, when the train passed beneath the motorway moments ahead of the truck. The race was on.







Road transport planners are always in the hands of other road users but there were no accidents or incidents to hold it back and the Actros, its range-topping 16-litre 600bhp governed to a 56 mph top speed, made steady progress, reaching Gretna Green services in four hours, 27 minutes. That was just three minutes shy of the statutory, four-and-a-half hours maximum driving period. The truck then had to remain parked for 45 minutes, its single driver being more representative of typical truck operation than a double-manned cab.



With CANbus data showing an average 52.4mph and 8.5mpg, the mighty MegaSpace was proving a reliable and economical partner.



Meanwhile, the £2-million train, its 3,245bhp, 139-litre engine capable of 75mph, was returning less than one mile per gallon and was on the second of the three sets of crew it needed for the same trip. Having already had one change of personnel at Crewe, it was forced to stop for pathing at Tebay, before heading on to Carlisle for a third and final crew change.



Some 270 miles in, just south of Moffat where the rail line and M74 Motorway run parallel, Beattock Hill was reckoned by both parties to be the make or break point of the journey. Surely, he who crested first would have gained a winning advantage…



Nervous tension set in as train and truck reached the top side-by-side and the combatants aboard made eye-to-eye contact for the first time. To reach the finish line the truck would still have to navigate the busy sprawl of Bellshill and the centre of Coatbridge. The train, meanwhile, could peel off, leaving those aboard to enjoy the spectacular Lanarkshire countryside.





Six hours and 55 minutes after it departed DRIFT Northamptonshire, the Actros arrived at the container terminal gates, the anxious driver nervously asking: “Has the train arrived yet?” Celebrations began when the reply came: “Nope, its still 18 minutes away!”



Commercial MotorManaging Editor Will Shiers, who made the journey aboard the Class 66, said: “I’m thrilled with this result, as it’s a resounding ‘thumbs up’ for road transport. This test has shown and proved that not only is road faster than rail, but rail freight couldn’t possibly exist without trucks.”



“When we reached Beattock, some five hours into our journey, I was amazed that we were running side-by-side; you could have thrown a blanket over us. It was a nail biting moment for sure, and for a while I feared the train was going to deliver a runaway success.”



Pip Dun,Editor of Railways Illustrated, added: “This test has proved very informative. I’m a huge supporter of both forms of transport and although my heart is with rail, I believe each has its place; indeed, in many ways they compliment each other. Seeing the entire journey through the windscreen of the Actros was an interesting experience and something I’ve wanted to do for a number of years. I can now understand some of the challenges the road transport industry faces.”
