The Mercedes-Benz M-Class designers worked hard to combine the interior expected in an SUV with the luxurious feel of the top Mercedes Saloons. While an expressive dome shape embodies the power of an SUV, the gently sloping dashboard in the front passenger area affords an outstanding sense of space, thereby highlighting the vehicle’s suitability for long journeys.
The evolution of the dashboard in Mercedes-Benz off-road vehicles, from the early days of the G-Class through to today’s new M-Class, makes it clear how much aspects of comfort and wellbeing have now come to the fore:
SUV environment with the comfort of a luxury saloon
The modern Mercedes-Benz definition of the appropriate interior of an SUV becomes evident as soon as the pleasantly high seating position is accessed via the wide-opening doors. The spacious, bright interior provides noticeably more elbow room than its predecessor (34 mm more in the front, 25 mm more in the rear) and thus an enhanced sense of space and comfort. The driver takes to the wheel behind a 4-spoke multifunction steering wheel with twelve trapezoidal control buttons for trip computer, radio, telephone, etc. – which is also of a high saloon standard. The 7G-TRONIC PLUS automatic transmission is controlled via the DIRECT SELECT DIRECT SELECT lever as well as DIRECT SELECT shift paddles on the steering wheel.
The broad instrument panel stretches out behind the steering wheel. With its clear emphasis on width, it continues the horizontal lines from the exterior design in the interior. Exciting areas and powerful lines highlight the vehicle’s sporty aspirations.
An eye-catching feature of the instrument panel is a large decorative trim element that is then continued along the doors in a very harmonious wrap-around effect. These generously proportioned trim elements, in a three-dimensional design, are available in four high-quality wood finishes, or in aluminium. The interior of the new Mercedes-Benz M-Class can thus be appointed to reflect either exclusive refinement or sporty sophistication, according to the customer’s taste. The door openers and seat adjustment switches have been inset with precision craftsmanship into the side trim elements. The door centre panels feature distinctive decorative stitching, with a separate, exclusive look for the Sports package.
All clear: instruments and COMAND screen
The state-of-the-art instrument cluster with its two clear and extremely legible round dials and a large, 11.4 cm monochrome display between them, impresses with the high quality of its design. Dominating the centre of the instrument panel in the centre of the vehicle is the large colour screen for the infotainment system. There is a choice between CD radio, CD radio with integrated navigation system or the COMAND control and display system with the latest navigation system (14.7 cm screen diagonal for the CD radios, 17.8 cm for the internet-enabled COMAND Online). The control and display concept was developed specifically with user-friendly operation in mind. Infotainment, navigation and communication systems are intuitive and easy to operate using the metal Controller located on the centre console. Two buttons are used to switch the display on and off.
Vertical rectangular air intake vents either side of the large screen serve to emphasise the more functional aspects of the SUV. The outer air vents are the same shape but in this case horizontally positioned, thus giving an added design flair. The dashboard console and air intake vents feature edging with a quality Silver Shadow finish. The row of high-gloss silver switches in the dashboard console are characterised by their ergonomic design and discernible precision. The same applies to the air conditioning and ventilation setting, as already proven in Mercedes-Benz saloons.
The centre console incorporates an integrated arm and handrest, in front of which is located the Controller and various switches, such as those for the off-road programmes and AIRMATIC air suspension. All controls feature a quality, uniform look. They create a harmonious effect and the lend the interior a touch of class in the many places in which they are used.
Numerous stowage facilities, high degree of variability and temperature-controlled cup holder
Numerous, easily accessible stowage facilities in the M-Class can accommodate bottles, mugs, keys, coins and much more. Each of the four doors can also easily accommodate a large 1-litre bottle.
A light touch of the handrest in the centre console opens up a large stowage compartment which houses a 12V socket as well as easily accessible connections for mobile audio devices. To make long journeys and extensive off‑road excursions more enjoyable, the centre console also features two innovative cup holders which can keep drinks either cool or warm at temperatures of between 8°C and 55°C.
High-quality materials and strong colour values
The seats in the new M-Class are designed to provide a high level of comfort on long journeys as well as excellent lateral support. All important parameters can be electrically adjusted, including height, backrest angle, seat cushion angle and reach. Generous seat adjustment travel of more than 350 millimetres lengthways and more than 90 millimetres in height ensure that drivers of all sizes will always find the ideal seating position.
A high level of variability characterises the rear seats, which are fitted with an armrest and cup holder. The angle of their backrests can be adjusted, and they can be also folded in the ratio 1/3:2/3, thus creating a through-loading feature for long objects, such as skis, without having to sacrifice all of the rear seat positions. 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 liner.
Exclusively available for the new M-Class are three seat and two sports seat variants in six different colour combinations. The sports seats reserved for the Sports package feature a different stitching pattern which is also incorporated into the door centre panels.
Four colours are available for the interior appointments: black, almond beige, alpaca grey and marron/tobacco brown. These can be combined with a wide range of materials: fabric/ARTICO man-made leather in black, ARTICO man-made leather and leather in six colour combinations, in conjunction with the Interior Sports package with DINAMICA microfibre and leather in black.
In line with the Mercedes-Benz brand philosophy, the new Mercedes 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. Both active safety and driver-fitness safety in the new M-Class are further improved by Assistance Systems, already primarily familiar from the S and E-Class.
As with all passenger car models from Mercedes-Benz, the philosophy behind the safety concept of the M-Class is broken down into four phases:
After an accident: avoiding even worse consequences and making rapid assistance possible
The very high level of safety already achieved in the previous model has been increased even further thanks to meticulous attention to detail during the development stage. The many “invisible” Mercedes-Benz solutions in particular bring measurable benefits in real accident situations. To support new technologies or the evolution of existing systems, the engineers carried out numerous crash tests which went way beyond the tests normally specified, such as the roof-drop test for example, as well as various rollover tests. When it detects the need to do so, a rollover sensor system can activate side and window airbags, as well as belt tensioners. In total, as part of the
M-Class development Mercedes-Benz tested 36 totally different loads under real test conditions. This included comprehensive simulations for the digital prototype. Following this intensive development programme, the M-Class now has the potential to pass all international ratings with the best possible results.
The M-Class is also able to demonstrate the highest possible protection potential when it comes to more vulnerable road users such as pedestrians or cyclists. In addition to yielding areas in the front section, folding exterior mirrors and smooth contours, the risk of injury caused by the vehicle has been reduced by adjusting the bonnet and increasing the distance to the components in the engine compartment. In addition, for the first time in the SUV segment, an active bonnet is fitted as standard equipment. It is able to reduce the acceleration forces of an impacting pedestrian or cyclist by intercepting them earlier.
“Electronic crumple zone”: even more safety in the M-Class
As ever, the best accident is one which does not happen at all. The safety engineers at the Mercedes Technology Center are working intensively on this rather simple sounding statement, which in practice is actually a lot more difficult to implement. Both active safety and driver-fitness safety in the new M-Class are further improved by the numerous active and passive assistance systems:
Standard equipment forming part of the safety concept of the new M-Class includes the anticipatory safety system PRE-SAFE®, which combines active and passive safety synergies to reduce the loads exerted on the vehicle occupants in the event of an accident by up to 40 percent. Depending on the potential accident situation detected, the following reversible measures can be initiated for preventive occupant protection:
Body: high energy absorption in the event of a front impact
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. The focus of the work here has been the tangible reduction of the loads exerted on the occupants. In the case of front impacts, the engineers were able to achieve more uniform deceleration, and therefore a lower peak load on the occupants. This was made possible by means of:
Side-impact protection thanks to intelligent bodyshell
Similar to the design of the front area of the new M-Class, the vehicle’s intelligent bodyshell design also performs impressively in side-impact accident scenarios. The specific distribution of high rigidity and high deformability helps to ensure that the occupants benefit from favourable kinematics in the event of a side impact:
Brilliant finish: the rear assembly of the M-Class
The rear area too of the M-Class also protects the sturdy passenger compartment in crash situations thanks to specific deformation work, therefore minimising the loads on the occupants. A special impact test conducted to check tank leakage gives an indication of the exceptional load capabilities of the rear part of the M-Class body. The test involved running a crash carriage into the rear of the M-Class at 80 km/h. The tank system survived this fatal impact without suffering any leaks.
To enhance rigidity, increase the energy absorbtion capability and improve deformation behaviour, the multi-piece rear longitudinal members feature a continuous closed cross-section with stepped plate thicknesses (tailored blanks). The spare wheel well forms an integrated part of the steel floor, and a steel flexible bumper bracket carries the rear bumper covering and is connected to the rear structure via two steel crashboxes.
Comprehensive restraint systems for even better occupant protection
The passive occupant protection systems, together with the “electronic crumple zone” and intelligent body design which have already been described, provide optimum protection potential, placing the M-Class at the top of its market segment. As part of this, a number of new deployment strategies are used. For example, the system can detect an impending rollover in the event of crash and if necessary deploy the head, side and window airbags, as well as the seat belt tensioners. Thanks to the new generously-sized side airbags and the window airbags with extended area of coverage, in the event of a crash the occupants can be more uniformly supported from the shoulder area down to the pelvic area, and thereby better protected. In side impacts too, the danger of injury is reduced thanks to extended coverage.
Additional protection potential is also provided for rear seat passengers with seat belt tensioners and force limiters on the outer seat positions. The integration of optional thorax bags in the tilt-adjustable folding seat backrests enables optimum airbag positioning for each backrest position. The components of the passive occupant protection systems include:
The M-Class also protects its occupants after a crash
As part of the POST-SAFE® functions, the new M-Class can activate a variety of systems which can contribute towards avoiding post-accident risks. After a more serious crash, the hazard warning lights are automatically activated to warn surrounding traffic. At the same time, the doors are automatically unlocked so that the emergency services have the best possible unrestricted access to the passengers. And thanks to partial opening of the side windows, the interior is better ventilated after deployment of the restraint systems.
On detecting a collision, the central control unit switches off the fuel system to reduce the risk of a possible fire. After determining the cylinder positions, the engine management system opens the injection valves of those cylinders which are not under compression and discharges the high-pressure fuel area by direct evacuation of the remaining fuel in the combustion chamber. This reduces the risk of fuel escaping. To avoid fuel losses, all M-Class models are also fitted with cut-resistant fuel lines in all relevant locations. This also helps to reduce the risk of a possible fire breaking out.
BlueTEC diesel units and the new generation of BlueDIRECT direct-injection petrol engines form the basis for the excellent economy and outstanding life cycle assessment of the new M-Class. In this respect, downsizing takes centre stage as far as the diesel models are concerned:

State-of-the-art engine technology from the inventor of the diesel passenger car
The 2.2-litre CDI engine turns the ML 250 BlueTEC 4MATIC into the most economical SUV in its class. With NEDC fuel consumption of 6.0 l/100 km, the model even outperforms any hybrid model currently offered by the competition. Despite the low fuel consumption figures, this M-Class model boasts maximum torque of 500 Nm at 1600 rpm and rated output of 150 kW (204 hp) with outstanding performance: the M-Class accelerates from 0 to 100 km/h in 9.0 seconds before going on to a top speed of 210 km/h.
Two-stage turbocharging produces high torque even at low engine speeds. The compressor package – already fitted in the compact SUV GLK 250 CDI 4MATIC – made up of a small high pressure (HP) and a large low pressure (LP) turbocharger contributes decisively to the high output on a par with the 6 cylinder unit in the predecessor model ML 300 CDI BlueEFFICIENCY 4MATIC. The two turbochargers are connected in series, and each has a turbine and a compressor driven by this turbine. The HP turbine is located directly at the exhaust manifold and initially allows exhaust gas to flow through it; it then rotates at up to 215,000 revolutions per minute. The HP turbine housing features an integral bypass duct, which can be opened or closed by means of a charge-pressure control flap. If the flap is closed, the whole exhaust stream flows through the HP turbine, so that the exhaust-gas energy is available solely for the HP turbine drive. This means that the optimum charge pressure can be built up at low engine revs.
The two compressors are likewise connected in series, and are in addition connected to a bypass duct. The combustion air from the air filter first flows through the low-pressure compressor, where it is compressed as a function of the LP turbine’s output. This pre-compressed air then passes into the high-pressure compressor, which is coupled to the HP turbine, where it undergoes further compression. The result is a genuine two-stage turbocharging process. The major advantage of this sophisticated, demand-related control of the combustion air supply using two turbochargers is improved cylinder charging, and therefore high torque even at low engine speeds. Fuel consumption is also reduced. When the car is driven, this concept makes itself felt by harmonious driving characteristics with no turbo-lag, a favourable torque curve across the entire engine speed range, instant responsiveness and excellent performance.
The V6 diesel engine in the ML 350 BlueTEC 4MATIC guarantees effortlessly superior traction. It develops 190 kW (258 hp) and impressive torque of 620 Nm. Despite its extraordinary performance this version boasts combined NEDC fuel consumption of 6.8 litres of diesel per 100 kilometres. The highly efficient V6 diesel unit delivers effortlessly superior performance: the ML 350 BlueTEC 4MATIC accelerates from standstill to 100 km/h in 7.4 seconds before moving on to a top speed of 224 km/h. While delivering performance on a par with the predecessor model, the ML 450 CDI 4MATIC with V8 diesel engine, the new unit, however, boasts 36 percent lower fuel consumption.
Just like the ML 250 BlueTEC 4MATIC, the ML 350 BlueTEC 4MATIC also ranks among the world’s cleanest diesel models: BlueTEC is a technology developed by Mercedes-Benz to reduce emissions from diesel vehicles, especially nitrogen oxides. AdBlue®, an aqueous urea solution is injected into the exhaust gas stream as part of this process, releasing ammonia, which reduces up to 80 percent of the nitrogen oxides into harmless nitrogen and water in the downstream SCR (Selective Catalytic Reduction) catalytic converter. Upshot: both models already comply with the EU6 exhaust emissions standard due to be implemented in 2014. The AdBlue® tank is located under the luggage compartment floor to protect it in the event of a crash, has a capacity of 25.7 litres and is topped up every 25,000 kilometres at the regular service intervals. The filler opening is located behind the side fuel filler flap alongside the tank filler neck and is marked clearly with a luminous blue cap. This configuration allows the ML driver to top up the tank easily if they take full advantage of the off-road capabilities of the M-Class and are unable to find a service station off the beaten track. AdBlue® is available as a refill container from any Mercedes-Benz dealership; the instrument cluster provides a timely indication of the need to top up the tank.
Latest-generation BlueDIRECT direct-injection engine for the ML 350 4MATIC BlueEFFICIENCY
The ML 350 4MATIC BlueEFFICIENCY petrol-engined model features the groundbreaking technology of the new generation of V engines from Mercedes-Benz. At the heart of the BlueDIRECT technology package lies the enhanced third-generation spray-guided direct petrol engine with piezo-electric injectors. In combination with multi-spark ignition, this technology offers further possibilities for fuel savings.
The V6 engine in the ML 350 4MATIC BlueEFFICIENCY utilises a new stratified combustion process with a considerably extended characteristic map and fuel-efficient lean-burn technology (“homogeneous stratified mode”). As the name implies, HOS is a combination of homogeneous lean-burn and classic stratified combustion. The first injection is sprayed into the intake stroke, forming a homogeneous basic mixture. Actual “stratified” injection takes place during the compression stroke before ignition, and is a single or double injection depending on the characteristic map.
The third-generation direct-injection system also features rapid multi-spark ignition (MSI). How it works: following the first spark discharge and a brief combustion period, the coil is rapidly recharged and a further spark is discharged. The MSI system enables up to four sparks to be discharged in rapid succession within one millisecond, creating a plasma with a larger spatial expansion than conventional ignition. Controlling this rapid multi-spark ignition enables both the time lapse before the next spark and the combustion duration for the relevant operating point to be optimally adjusted. This provides scope for optimising the centre of combustion and improving residual gas compatibility, especially during stratified charge operation.
The ultra-modern 3.5-litre V6 unit has been designed as a naturally aspirated engine. As a major distinction from the preceding engine in the ML 350 4MATIC, the V-angle between the cylinder banks has been reduced from 90 degrees to 60 degrees. This has enabled the balancer shaft compensating primary vibrations to be omitted. As a result the driver notices an outstanding level of comfort. The design highlights of the 3.5-litre V6 include a completely new air intake and exhaust system in conjunction with a variable resonance intake manifold and optimised inflow and outflow. Result: with the same displacement, the output compared with the previous 200 kW (272 hp) model is increased by 12.5 percent to 225 kW (306 hp), while maximum torque has increased by 5.7 percent to 370 Nm (predecessor: 350 Nm) and now is available over a broader engine speed range from 3500 to 5250 rpm. In parallel with this substantial increase in power, Mercedes engineers have achieved an equally impressive reduction in fuel consumption. The predecessor’s NEDC fuel consumption has been reduced by 25 percent. The new V6 petrol engine in the ML 350 4MATIC BlueEFFICIENCY consumes 8.5 litres per 100 kilometres, making it the most economical petrol model in its class. The model combines excellent consumption figures with dynamic performance, accelerating from standstill to 100 km/h in 7.6 seconds, and with a top speed of 240 km/h.

New dimensions in energy efficiency
The performance of the M-Class engines becomes particularly apparent when looking at the reduced energy requirements coupled with a marked increase in power output per litre for the three M-Class generations since 1997. Comparison of the weight-specific consumption figures (l/100 km per 100 kg) reveals the tremendous development potential of the conventional internal combustion engine:
Long-distance champion: a high level of efficiency ensures a long range
The range for a full tank of fuel on the new M-Class is particularly impressive. This parameter is very important for a vehicle that knows virtually no bounds. Here, the ML 250 BlueTEC 4MATIC – the most economical SUV in its class by far – stands out. With NEDC consumption of 6.0 l/100 km, the frugal diesel engine 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.

| Range per full tank of fuel km |
1170 | 1500 | 1030 | 1370 | 920 | 1090 |
Attention to detail: a fine finish adds efficiency
The excellent fuel economy is underpinned by a comprehensive package of BlueEFFICIENCY measures as well as by this state-of-the-art engine technology. In addition to the ECO start/stop function that comes as standard, these measures include the new seven-speed 7G-TRONIC PLUS automatic transmission. Low-friction axle drives, electric steering and tyres with low rolling resistance also play their part in reducing fuel consumption.
The re-engineered 7G-TRONIC PLUS, standard on all M-Class models, boasts an integrated ECO start/stop function, even lower converter slip and optimised efficiency. A central role is played by the new torsion damper, which eliminates torsional eccentricities and vibrations in the transmission even more effectively. The lower the rpm and the lower the number of cylinders, the more severe these can be. This results in a conflict of aims between comfort and fuel-efficient operation. Mercedes-Benz developers resolved this by using a so-called twin-turbine damper, which is also fitted with a centrifugal pendulum on the diesel models. Depending on the rpm, this moves the centre of mass and allows comfortable operation even in the most economical operating range. Furthermore, the optimised damping allows a marked reduction in the slip of the torque converter lockup clutch even under low loads, which also contributes to fuel savings. In addition, the optimised damping of rotational irregularities and vibrations in the transmission allows an even faster response to driver commands via the accelerator pedal. Friction-optimised bearings and new transmission oil thermal management also help reduce fuel consumption.
The optimised belt drive system with decoupler, together with intelligent, on-demand control of all ancillary components and pumps, also helps to reduce the energy requirements of the new M-Class. The oil and water pumps in the engine, as well as the fuel pump in the rear section of the vehicle, are only activated according to actual need. The same control logic is used in the THERMATIC and THERMOTRONIC air conditioning systems. In these, the coolant compressor only runs when necessary. An internal heat exchanger and the sophisticated sensor system including a demisting sensor on the front windscreen ensure optimum efficiency of the air conditioning systems in the interior. A key factor in the diesel engines is also the optimisation that has been undertaken of the flow and counterpressure in the exhaust system with its SCR emission control technology.
A consistent use of lightweight construction techniques has enabled the development engineers to keep the weight of the new M-Class on a par with that of its predecessor, despite more equipment. The links on the front and rear axles, for example, along with the bonnet and wings, are made out of light and yet very strong aluminium alloys, while the cross member for the instrument panel is made of magnesium.
Optimised aerodynamics: the most aerodynamic SUV in its class
With a drag coefficient, or Cd value, of 0.32, the new M-Class (ML 250 BlueTEC) also sets a new best figure for this vehicle class (total aerodynamic drag Cd x A = 0.92, predecessor 0.94). Painstaking 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 bodyshell, including the optimised design of the front bumper with its integrated spoiler, of the A‑pillars and of the roof spoiler, plus numerous other detailed improvements.
These include:
Detailed analysis: “energy-transparent vehicle” creates transparency
The “energy-transparent vehicle” development tool, created in-house by
Mercedes-Benz, was piloted as part of the M-Class development process. The outstanding opportunities presented by this method, which can detect the possibilities for optimisation in even the most minute component, will be exploited on all new model series in the future. An exact and meticulous examination of the flow of energy throughout the vehicle (tank to wheel) helps the development engineers to optimise every single assembly that has an impact on fuel consumption, right down to individual components, such as wheel bearings.
The idea for the “energy-transparent vehicle” stemmed from the failure in the past to verify or demonstrate clearly the many factors affecting consumption and the interaction between fuel-saving measures. Using the “energy-transparent vehicle” tool, the engineers can now detect detailed potential optimisation measures by breaking down energy flows into cause and effect and analysing energy interactions within the entire vehicle.
The process draws on complex, highly precise metrology which records some 300 energy-relevant measurement points with a sampling rate of up to 1000 measured values per second. Every minute some 2.4 million measured values are generated, which can subsequently be analysed to reliably pinpoint optimisation potential. The process is complemented by energy simulation models which are validated by means of the measured variables. This enables the energy efficiency of individual major assemblies and components as well as the entire vehicle to be analysed and quantified.
Once the specialists have identified a vehicle component with energy shortcomings, they team up with the relevant specialist departments to devise solutions. This cooperation focuses on design, or the properties of the materials used in individual vehicle components such as wheel or axle bearings. In addition, modified control strategies can also produce the desired outcome.
The “energy-transparent vehicle” process which is exclusive to Daimler enables the development engineers to highlight and leverage optimisation potential both for cars with conventional internal combustion engines as well as hybrid, electric or fuel-cell drives. In future, this process may even give rise to a generally applicable development tool for all machines and help boost energy efficiency across the board. A wide range of applications are conceivable. Whether in industry for power stations, (wind) generators, pumps or conveyor systems, in the home for refrigerators, washing machines, dryers and lawnmowers, or for transportation applications involving ships, trains or planes – the optimisation potential of disparate technologies to save energy could be analysed in detail with the consistent usage of this technique and implementation recommendations made.
The third generation of the M-Class sets new benchmarks in the SUV segment with its cutting-edge automotive technology. The new M-Class from Mercedes boasts optimum energy efficiency, leading standards of passive safety and unmatched ride comfort combined with superior driving dynamics. In addition, the SUV has a completely revamped interior design offering excellent ergonomics among its key strengths.
The low fuel consumption and exemplary emissions figures make impressive reading – on average, the entire model range burns 25 percent less fuel than the predecessor. Never before has Mercedes-Benz succeeded in cutting fuel consumption by such a huge margin with an SUV model change. An ultramodern engine line-up, a class-beating Cd value of 0.32, extensive BlueEFFICIENCY measures, as well as new development tools such as the “energy-transparent vehicle” all play their part in delivering the good energy efficiency figures. The ML 250 BlueTEC 4MATIC is particularly outstanding in this respect: it is 28 percent more economical than its predecessor, consumes just 6.0 l per 100 km on the NEDC driving cycle (158 g CO2/km) and can cover as much as 1500 kilometres on a single tank of fuel.
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 from what happens in a real accident situation. In combination with the front and rear deformation zones, the high-strength passenger cell of the M-Class provides a highly effective foundation for the occupant protection systems. 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-Class and E-Class.
All models in the new M-Class range offer excellent comfort and dynamic handling as standard – both on the road and away from the tarmac. Besides the steel suspension with selective damping, there are also some new chassis developments and innovative dynamic handling control systems available, which are designed to make driving the new premium SUV an even more effortlessly superior experience. These include the AIRMATIC air suspension with Adaptive Damping System (ADS), the ACTIVE CURVE SYSTEM for active roll stabilisation and the ON&OFFROAD package with six driving modes. A comprehensive package of measures has also been included to ensure that the M-Class is at the forefront of its segment for acoustic and vibration comfort too.
The third generation of the highly coveted Mercedes-Benz M-Class SUV combines the best of both worlds, boasting a strong off-road heritage at the same time as making its passengers feel as if they are travelling in a luxury premium saloon. Ground aluminium or exquisite woods as well as the finely detailed switches and trim highlights blend with electrifying surfaces and powerful, harmonious lines to create a high-class interior ambience and a tremendous sense of wellbeing for both the driver and passengers.
Excitement over the 2012 Mercedes-Benz M-Class has been building over the last few months as multiple leaks have been posted. Finally, however, the SUV set to debut at teh Frankfurt Motor Show later this year has been officially unveiled. The completely redesigned M-Class offers a bold front grille, sculpted sides, wraparound taillights, 17″ – 21″ Alloy wheels and a noteable interior update.
The 2012 ML shares its platform with the 2011 Jeep Grand Cherokee, with an optional self-leveling Airmatic suspension with selective damping available, as well a new “On&Offroad” package that offers six different transmission modes to match driving conditions.
At the launch of the M-Class, there will be three different engines offered. The entry-level ML 250 Bluetec has a 2.1-liter four-cylinder diesel that produces 204 PS (150 kW / 201 hp) and 369 lb-ft (500 Nm) of torque.
The ML 350 Bluetec comes with a 3.0-liter V6 diesel engine with 258 PS (190 kW / 254 hp) and 457 lb-ft (619 Nm) of torque.
The ML 350 BlueEfficiency has a 3.5-liter V6 engine that offers 306 PS (225 kW / 302 hp) and 273 lb-ft (370 Nm) of torque.
We will bring you even more specifics shortly, but we want to hear what you think of the 2012 Mercedes-Benz M-Class.
Even more visually expressive and with an even more elegant and comfortable interior, Mercedes-Benz presents the new GL-Class “Grand Edition”. This distinctive, new special edition of the off-roader comes as standard with a level of spaciousness and comfort that is on a par with a luxury saloon. Features reserved exclusively for the “Grand Edition” designation include special light-alloy wheels with 275/50 R 20 tyres, high‑quality, two-tone leather seats in a new design, and wood trim in black ash. The special Grand Edition model also offers an array of high-quality additional equipment and is available with all the engines in the GL-Class line-up.
The exclusive front end of the “Grand Edition” is unmistakeable: dark-tinted headlamps, a radiator grille with black, high-gloss louvres and a redesigned front bumper with integrated LED daytime running lamps define the special model. Light-alloy wheels in himalayas grey metallic – with a high-sheen finish also available as an option – add further exclusivity. There are other visual highlights too, such as metallic paint finishes, heat-insulating and infrared-reflecting laminated glass all round, aluminium-look running boards with rubber studs, and separated exhaust tailpipe trim.
The interior of the GL-Class accommodates up to seven occupants in comfort with an exceptional level of spaciousness, creating the luxurious atmosphere you would expect from Mercedes-Benz – in this case comparable to the S-Class. For the “Grand Edition”, Mercedes-Benz has refined the interior further, especially through the use of stylish materials. Exclusive appointments include two-tone seats (black/porcelain or black/maroon) in leather (or in nappa leather as an option) with a special piping design and contrasting stitching.
Likewise only available on the “Grand Edition” are door centre panels, armrests and dashboard instrument panel with double-lapped felling, as well as trim and a wood/leather steering wheel in black ash.
Other high-quality appointments: comfort headrests for the driver and front passenger, ambient lighting, roof liner in black designo fabric, velour floor mats with contrasting stitching and “Grand Edition” lettering, “Grand Edition” badge on the centre console, sports pedals in brushed stainless steel with rubber studs and door sill panels in stainless steel.
Powerful and economical engines
The “Grand Edition” models are equipped with PARKTRONIC and any one of the available engines. The V6 diesel engine in the GL 350 BlueTEC 4MATIC utilises highly efficient SCR exhaust gas technology, outputs 155 kW (211 hp) and delivers its maximum torque of 540 Newton metres at 1600 rpm. On average this engine consumes 9.0 litres of diesel per 100 kilometres. In the GL 350 CDI 4MATIC BlueEFFICIENCY, the V6 engine outputs 195 kW (265 hp) and generates torque of 620 Newton metres. It consumes 8.9 litres per 100 kilometres.
Superior power delivery and maximum smoothness are the particular benefits of the two petrol V8 models. These models also comply with the EU5 emissions standard. The 5.5-litre V8 engine in the GL 500 outputs 285 kW (388 hp) and delivers 530 Newton metres of torque. At 6.5 seconds, its acceleration time from a standstill to 100 km/h is almost worthy of a sports car. On the GL 450, the V8 petrol engine has a displacement of 4.6 litres, outputs 250 kW (340 hp) and generates maximum torque of 460 Newton metres. It takes 7.2 seconds to sprint from 0 to 100 km/h.
Agile and safe both on-road and off-road
With innovative 4MATIC all-wheel drive, AIRMATIC air suspension as standard, the accurate Direct-Steer system and the Adaptive Damping System ADS, which also comes as standard, the commanding GL-Class offers impressive handling, guaranteeing excellent ride comfort coupled with outstanding active safety. While the GL cuts an imposing figure on the asphalt, it also has genuine off-road credentials. The modified AIRMATIC air suspension enables ground clearance of up to 307 millimetres. Thanks to its low-range ratio and limited-slip rear-axle and centre differentials, the standard Off-Road Pro technical package opens up considerably more possibilities on challenging terrain. Other electronic dynamic handling control systems such as Off-Road ABS, Downhill Speed Regulation (DSR) and Hill-Start Assist also make life easier for the GL-Class driver.

AMP Electric Vehicles, a company offering emission-free electrification of OEM vehicles, AMP handed over the keys of an electric Mercedes-Benz ML 350 to the company’s newest and biggest client, Gisli Gislason, the chairman and chief executive of Northern Lights Energy, a utility in Iceland.
This is the initial delivery committed in AMP’s long term supply agreement with the Icelandic company signed on April, 14, 2011. The Mercedes SUV was just the first vehicle produced in accordance with the five-year contract between the two companies, during which Amp expects to ship 1,000 E.V.’s to the island nation.
In the past, Amp has converted only General Motors passenger cars, primarily the Chevrolet Equinox crossover.. The Mercedes-Benz ML’s proportions are similar to those of the Equinox, which helped in the conversion, particularly to house the company’s 900-pound battery unit.
“We retained a split battery pack to keep the weight balance about equal to the original manufacturer’s specification,” said Steve Burns, president and co-founder of Amp, in a telephone interview. “We can even lower the center of gravity a bit to give it better handling.”
The ML’s global distribution was also a consideration for Amp. “It’s a world car, so it’s already passed Euro and U.S. crash-safety tests,” he said. “That’s the benefit of our approach; we didn’t have to worry about developing a defroster or a windshield wiper.”
Amp is not committing exclusively to the ML as its future platform, nor is it trying to lock up a contract with one battery supplier (Mr. Burns declined to name the current supplier of its batteries). This is an advantage of the company’s business model, Mr. Burns said. “We have a five-year contract, so you can imagine what batteries will do during that time,” he said. “We try to be battery agnostic.”
Mr. Burns estimates that the ML should travel 100 miles on a charge in pure highway driving, which compares favorably to the estimated range of the Nissan Leaf, despite the ML weighing nearly 2,000 pounds more than the purely electric Nissan.
Though primarily an electricity provider, Northern Lights will function as a distribution channel for the Amp vehicles. Mr. Gislason is working to secure orders from companies, municipalities and individual buyers in Iceland, who, according to Mr. Gislason, should be easy quarry.
“Gasoline is about $8 a gallon right now, and Iceland has low import taxes on E.V.’s,” he said in a telephone interview. “A Mercedes S.U.V. would be basically the same price to import, plus you’d have to purchase gas. For us, it’s a no brainer.”
Iceland also generates much of its electricity through geothermal and hydroelectric sources, which increases the cost benefit of E.V. operation, he said.
The utility’s agreement with Amp is not exclusive, so Northern Lights could conceivably become partners with other E.V. manufacturers. However, Mr. Gislason does not expect that to occur soon. “Amp can deliver us cars. Today, they gave us a real car. We’re not being told by a big manufacturer, ‘Oh, there’s a delay.’ We’re getting them right now.”
Mercedes-Benz is welcoming spring with two new, luxuriously equipped special G-Class models. Among other enhancements, an extensive stainless steel package and mounted AMG features ensure a visually striking appearance for the “BA3 Final Edition” based on the short-wheelbase Station Wagon and the “Edition Select” with a long wheelbase. In the interior a Chrome package and many more comfort-enhancing extras dominate the ambience of this classic, which has continued to enjoy the affection of off-roader fans worldwide for no less than 32 years.
A classic off-roader is entering its final phase: as the model designation suggests, Mercedes-Benz is producing the last edition of the short wheelbase Station Wagon in the successful G-Class with the special “BA3 Final Edition” model. Two variants will be available: in the G 350 BlueTEC a 6-cylinder diesel engine with the very latest BlueTEC emissions control, 155 kW (211 hp) and 540 newton metres for great pulling power both on and off the road. In the G 500 a powerful 5.5-litre V8 petrol engine with 285 kW (388 hp) and 530 newton metres effortlessly performs the same function.
Both special models of this classic among Mercedes-Benz off-roaders are equipped with the same high-performance drive and dynamic handling control systems. Alongside the permanent all-wheel drive with off-road ratio and the 7G-TRONIC seven-speed automatic transmission, the standard specification includes the electronically controlled traction system 4ETS, the Electronic Stability Program ESP® and three differential locks with 100-percent locking effect selectable at the push of a button.
Externally Mercedes-Benz has significantly upgraded the “BA3 Final Edition”. AMG flared wheel arches in the vehicle colour, in combination with 5-twin-spoke light-alloy wheels and tyre size 265/60 R 18, underline the striking appearance of the special model. Running boards and a spare wheel cover with a 3D Mercedes-Benz star in stainless steel, as well as an AMG radiator grille in a 3-louvre design with chrome highlights, emphasise its exceptional position in the range. Standard features also include an electric sliding/tilting sunroof, metallic paintwork, rear mudflaps, carbon-fibre look inserts in the protective strips, an ultrasonic reversing aid and a tyre pressure monitoring system.
In the interior the driver and passengers are able to enjoy even more generous appointments. Fine details and high-grade technology raise both visual appeal and comfort to a new level. Further highlights are provided by stylish yet functional ambient lighting, as well as chrome highlights on the frame and selector lever cover, seat adjustment controls and the loudspeakers in the front doors. Another eye-catching detail is the chrome luggage compartment sill panel with “Mercedes-Benz” lettering.
Outstandingly high seating comfort is assured by the multicontour front seats in black leather with seat climatisation. These offer first-class comfort on long journeys, even in mid-summer temperatures. They are accompanied by burr walnut wood trim, and the same, high-grade wood plus leather adorns the steering wheel and selector lever.
Standard equipment also includes a convenience telephony system in the armrest, with a universal interface for various mobile phone cradles, extended telephone functions, a charging function and an external aerial for optimum reception. Useful accessories include rubber mats for the footwells and load compartment, as well as a load compartment cover including additional stowage boxes.
As the G 350BlueTEC the “BA3 Final Edition” is priced at € 90,511.40, and as the G 500 € 100,685.90 (both prices include 19% VAT).
Special “Edition Select” model
Mercedes-Benz has conceived the special “Edition Select” model with two-tone paintwork exclusively for the long-wheelbase G 500 Station Wagon. At no extra cost, there is a choice of designo mystic white, palladium silver metallic, thulite red metallic and obsidian black metallic. The bumpers, AMG side flaps and exterior mirrors are always painted in obsidian black metallic. Further contrasts are provided by running boards and the spare wheel cover with a 3D Mercedes-Benz star in stainless steel. Other eye-catching features include black-painted 18-inch light-alloy wheels in a 5-twin-spoke design with size 265/60 R 18 tyres, carbon-fibre look inserts in the protective strips, an underguard and an AMG sports exhaust system.
In the interior the stylish atmosphere is characterised by high-grade two-tone upholstery in porcelain/black designo leather. Single-tone black designo leather is available as an alternative. Ambient lighting and chrome trim in the area of the selector lever, the seat adjustment controls and the loudspeakers in the front doors underline the luxurious standard. The Chrome package is rounded off by a chrome luggage compartment sill protector with “Mercedes-Benz” lettering and a radiator grille with chrome inserts.
The dashboard, armrest, door handles and parking brake lever are lined in black leather, with contrasting topstitching is some areas. The inner door panels are lined with gathered leather, and black designo velour floor mats with porcelain edging lend a cosy touch to the footwells. Highlights in the interior also include designo wood trim in black piano lacquer. The steering wheel and selector lever are in a leather/piano lacquer combination with contrasting topstitching.
The already extensive standard equipment is supplemented with stainless steel door sill panels illuminated in white and bearing the lettering “Mercedes-Benz”, as well as crash-responsive NECK-PRO luxury head restraints. The Harman Kardon Logic7® surround sound system is among the finest available. It provides an exquisite listening experience in the off-roader, thanks to a 10-channel DSP amplifier with a total output of 450 watts and twelve high-performance loudspeakers.
The high-grade additional features of the special “Edition Select” model, whose status is marked by a corresponding logo on the cover of the stowage compartment in the dashboard console, are priced at € 6735.40 (incl. 19% VAT).
Back in 2009, we heard that Mercedes-Benz and AMG had plans to replace its entire engine lineup with a new range of more fuel efficient direct-injected and turbocharged powerplants. A few months later we had official details on one of the most anticipated of the newcomers, a 5.5-liter V-8 that is to replace the 6.2-liter unit found in the current AMG lineup.
It was codenamed M157 and had plans to offer serious power. The new 5.5-liter engine is set to feature direct-injection and twin-turbocharging technologies, this to ensure it produces more power and torque than the current 6.2-liter naturally aspirated mill. Peak output stands at 544 horsepower and 590 pound-feet of torque, however, an available Performance Pack sees output increased to 571 horsepower and 664 pound-feet of torque thanks to additional boost pressure from the turbos.
After news of the engines, spy photos began coming in. And this weekend, the next generation ML AMG SUV was spied again by Motor Authority. Though still heavily covered, we are able to now see the fabricated air intake pipes on the front bumper and air vents on the hood. Thanks to the latest photos, we also get a good look at the large disc brakes at the front and the new AMG wheels, also expected on the next-generation GL AMG SUV. A new bumper and quad exhaust exhaust can be found at the rear.
Almost certain to pick up the performance division’s new twin-turbocharged 5.5-liter V-8, the speedy SUV will be called the ML63 AMG and will likely be launched soon after the standard version later this year. The new V-8 engine produces more power and torque than AMG’s current 6.2-liter naturally aspirated mill, with output peaking at 544 horsepower and 590 pound-feet of torque. However, a likely available Performance Pack should see output increased to 571 horsepower and 664 pound-feet of torque thanks to additional boost pressure from the turbos.
Signs that this is most certainly the AMG variant are the oversized cross-drilled brakes and dual exhaust tailpipes. We can expect a slightly lowered ride height as well as a sports tuned suspension.
The aftermarket specialist from German tuner Kicherer have divulged information on their all new the Mercedes GL 42 Sport Black. The Kicherer Mercedes GL 42 Sport Black is based on the Mercedes-Benz GL-Class 420 CDI and offers a complete package with visual and performance modifications.
The current Mercedes-Benz GL420 CDI offers a 4.2 liter V8 common rail diesel engine with 306 hp and 700 Nm of torque. With help from Kicherer, the SUV’s power output increases to 380 hp and 900 Nm of torque. The Kicherer GL 42 Sport also comes with a PowerConverter from the company that enhances acceleration pedal response.
The exterior of the GL Tuner is a matte black foil finish and the grille and Mercedes-Benz badges all re-done in black. Additional exterior features include 22-inch rims, an off-road package with electronic chassis adjustment as well as a 2-pipe sports exhaust system. On the interior is an upgraded ergonomic sports steering wheel.
Kicherer Press Release:
GL 42 Sport Black – The exception
The Mercedes Benz GL class is extremely impressive even in its serial version. At a length of 5.09 meters, width of 1.92 meters, height of 1.84 meters and a combat weight of approx. 2.5 tons, the X164 series – which has been available since 2006 – towers over nearly all the other full size SUVs without seeming plump. KICHERER Fahrzeugtechnik from Stockach at the beautiful Bodensee specialize in Mercedes-Benz refinement; they emphasize the sportive characteristics of this large SUV with strategically placed tuning measures: Raise the curtain for the KICHERER GL 42 Sport Black! Send through Y!M E-mail this
The special edition based on a Mercedes Benz GL 420 CDI is powered accordingly by a 4.2 liter V8 common rail turbo diesel engine; in the series state, it has 306 HP and 700 Newton meters as maximum torque. The performance improvement by KICHERER provides the GL 42 Sport Black with a full 380 HP and 900 Newton meters on the thick crankshaft. The additionally installed KICHERER PowerConverter also sharpens the electronic gas pedal characteristic curve, causing the heavy vehicle to react even more spontaneously to acceleration commands and enabling powerful acceleration from the very bottom. The two end pipes of the two-pipe sports exhaust system give off a deeply evil roar
The serial Airmatic chassis was also given a more sportive characteristic curve, making the GL 42 Sport Black comparatively light on it wheels when going around bends of any size. The Vogue complete wheel set consisting of 10×22 inch wheel rims and XXL size 295/35R22 tires also essentially contributes to the new driving dynamics.
For a sportive look, KICHERER retrofitted the GL 42 Sport Black, which is completely covered in matte black exclusive foil, with its own off-road package. The grille and all the Mercedes stars and decorative strips are now black to perfect the SUV’s “bad boy” look. KICHERER also improved the cockpit with the contoured ergonomic sports steering wheel.
Modifications
The Brabus 800 WIDESTAR, based on the Mercedes-Benz G-Class SUV, is the world’s most powerful off-roader. Debuting at the 2011 Geneva Motor Show, the Brabus G-Wagon is powered by an ultra powerful twelve-cylinder bi-turbo high-capacity engine with a rated power output of 800 hp (788 bhp) / 588 kW. You may remember its predecessor, the Brabus G V12 S with 700 hp (690 bhp) / 515 kW. Style wise, the powerful off-roader sets itself apart with its WIDESTAR wide-body equipment and enormous 23-inch Brabus “PLATINUM EDITION” forged wheels.
The five-door Brabus is built by hand keeping design elements from the current Mercedes G-Class. Like all special models from Brabus, the Brabus 800 WIDESTAR is available with an ample luxury equipment package.
As the name indicates, the Brabus 800 V12 Biturbo engine is implanted into the engine bay of the G-Class. The elaborate implantation of the twelve-cylinder engine is as much a masterwork as is its design, which is based on the V12 bi-turbo engine from the current Mercedes S 600 model.
The basis for the enormous increase in power is the displacement increase. Displacement of the three-valve engine is increased from 5.5 to 6.3 liters (336 to 384 cubic inches) in the state-of-the-art Brabus engine shop with the help of a special crankshaft with longer stroke and larger pistons and corresponding cylinder bore. Additionally the cylinder heads are optimized for mixture flow and fitted with special camshafts.
The engine peripherals now include an entirely new intake system and the Brabus 800 bi-turbo system with two special manifolds with integrated turbine housings and high-performance turbochargers, and four water-to-air intercoolers. This ensemble is joined by a stainless-steel high-performance exhaust system custom-developed for the Brabus 800. It features free-flow metal catalysts and four chrome tailpipes that exit in pairs in front of both rear wheels.
Precision mapping for engine electronics coordinate the perfect interaction of all new components and ensures exemplary smoothness, maximum power yield and low emissions.
With these modifications the engine in the Brabus 800 WIDESTAR delivers a staggering rated power output of 800 hp (788 bhp) / 588 kW at 5,500 rpm and an even more impressive peak torque of 1,420 Nm (1,047 lb-ft), already available from a low 2.100 rpm. In the vehicle peak torque is limited electronically to 1,100 Nm (811 lb-ft). The high-tech lubricants for the entire powertrain come from technology partner ARAL.
Driving performance speaks for itself: Combined with a reinforced five-speed automatic transmission and permanent four-wheel drive the engine shoots the Brabus 800 WIDESTAR from rest to 100 km/h (62 mph) in just 4.0 seconds. Top speed is electronically limited to 240 km/h (149 mph). Without the limiter the high-performance off-roader would be capable of reaching 270 km/h (168 mph).
In keeping with its unique performance the Brabus supercar also sports a delectable exterior: The Brabus WIDESTAR wide-body version lends the classic G-Class body an even more striking and dynamic profile.
The powerfully shaped fender flares add 12 centimeters (4.7 in.) to the body width. They feature integrated air outlets for optimized venting of the wheel wells. Strikingly styled door moldings give the sides of the G-Class high recognition value. Sturdy stainless-steel running boards facilitate entering and exiting of the vehicle day and night. LED lights integrated into the front and rear WIDESTAR fenders illuminate the running boards whenever a door handle is pulled or the keyless fob is operated.
The WIDESTAR fender flares create space for extremely large wheels and tires. Brabus offers the owner of the wide-body version, which is also available for all regular five-door G-Class models, a wide range of custom-tailored tire/wheel combinations with diameters between 20 and 23 inches. The most exclusive option for the 800 WIDESTAR features size 11Jx23 wheels front and back. Customers can choose from two newly developed forged wheels, the three-piece Monoblock E evo “PLATINUM EDITION” design or the one-piece Monoblock F “PLATINUM EDITION” wheel. The high-performance tires in size 305/35 R 23 come from Pirelli or YOKOHAMA.
The Brabus WIDESTAR version offers not just a wider track but also an even more impressive appearance. The front apron continues the shape of the flares on both sides and provides the engine and front brakes with cooling air through generously dimensioned air inlets. At the same time its sophisticated contour also reduces lift on the front axle. Six stylishly integrated auxiliary headlights optimize active safety at night. During the day the Brabus LED daytime running lights below the main headlamps draw attention to the power-G.
The design style of the front apron with its tapered flares and stylized underride guard is continued on the rear apron. The WIDESTAR rear bumper features a centrally mounted reflector and a fog lamp and backup light on either side. The designer suite is rounded out by the Brabus roof spoiler with integrated LED brake light.
For a perfect combination of sporty handling and excellent ride comfort the Brabus 800 WIDESTAR comes equipped with the innovative Brabus Ride Control smooth-ride suspension. The Brabus high-tech suspension system was developed in cooperation with technology partner BILSTEIN, and features two-way electrically adjustable shock absorbers front and back.
At the push of an aluminum button with Brabus logo on the center console the driver can manually choose between two setups: In comfort mode the off-roader offers exemplary ride comfort. At higher speeds or for more spirited driving selecting the firmer damper setting results in more dynamic handling and further increased safety reserves.
Additionally the Brabus Ride Control suspension features automatic damper adjustment. When the vehicle sensors detect that certain parameters such as speed, lateral acceleration and steering angle might lead to a critical situation the system automatically switches to the firmer sport setting within milliseconds. The sportier damper setup further increases the directional stability of the 4×4. The CAN control unit also detects a return to a more moderate driving style. It then automatically switches the shock absorbers back to the comfort position.
Another active safety feature is the Brabus high-performance brake system. The front axle is fitted with six-piston aluminum fixed calipers and vented discs with a diameter of 380 millimeters (15.0 inches). The rear stops on four-piston aluminum fixed calipers and 345-mm discs (13.6 inches).
The cockpit of the Brabus 800 WIDESTAR is exclusive and individual. The equipment list includes an ergonomically shaped sport steering wheel, a speedometer with 280-km/h (182-mph) dial and stainless-steel scuff plates with illuminated Brabus logo.
The Brabus interior is custom-tailored to suit the individual owner’s taste and the especially soft and breathable Brabus Mastik leather and Alcantara is available in a multitude of colors. Customers can also choose from various upholstery designs and the wood trim can be manufactured in any desired color. Upon request the wood elements can even be finished in the especially exclusive yachting design.
In 2008, RENNtech unveiled the GLK350 Hybrid Pikes Peak Rally Car, a concept vehicle which won the 2008 SEMA Show Mercedes-Benz tuner build off competition. This vehicle was designed not only to turn heads as a show car, but to serve as a proof-of-concept and testament to their dedication to a core concept; performance without compromise. Fast forward nearly 3 years, countless automotive trade shows, numerous track events and extensive real world miles; the GLK Pikes Peak project has been completely revamped and restyled for a final tour in 2011 with Mercedes-Benz USA.
Upon completion of the US tour schedule, the GLK will retire to a place of honor in the Mercedes-Benz Classic Vehicle Museum located in Irvine, CA as part of their permanent collection. This will be the second vehicle prepared by RENNtech that has found its way into the hallowed halls of the Mercedes-Benz Museum Collection, the first of which was the E60 RS project car built for comedian Jerry Seinfeld.
When approached with the opportunity, RENNtech completely revamped the vehicles exterior and collaborated once again with 3M Commercial Graphics Division to complement the GLK’s aggressive exterior styling. This original body kit was entirely designed and engineered by RENNtech in-house, using the latest in Computational Fluid Dynamics (CFD) software and rapid prototype capabilities. The concept behind the restyling was to not only completely change the vehicles appearance, but utilize vinyl materials in finishes rarely seen in the automotive world. 3M chose the RENNtech GLK as the showpiece to revel their latest product line of 1080 Scotchprint ® textured automotive vinyl wrap. This preprinted, 3.5 mil dual cast film was applied to nearly every exterior surface of the vehicle in a stunning combination of brushed steel (1080-BR201) and black carbon fiber (1080 CF-12) with subtle red pin stripping to further accent the vehicles bold lines.
The GLK350 Pikes Peak Project was unveiled to the public during Mercedes-Benz’ first leg of their tour schedule at the Pittsburgh International Automotive Show February 10-13th, 2011. Additional stops on the tour schedule include Milwaukee, Cincinnati, Cleveland, Kansas City, Minneapolis and Denver. After its time on the road, the vehicle can be seen at the Mercedes-Benz Classic Vehicle Museum in Irvine, California.
RENNtech worked with and was supported by several companies that can be seen below.
The 2012 Mercedes-Benz GL SUV has been popping up in spy photos since July of last year and once again the disguised GL-Class was spotted. The latest and most revealing photos of the next-generation Mercedes GL-Class show the SUV winter testing in Sweden.
The front of the SUV is more easily seen than in the past allowing us to get a good look at the headlights and larger R-Class style grille. The rear is still heavily disguised leaving us with only guesses of what the back end will look like. As we previously mentioned, the next GL will be larger than the current model and will be offered with a wide range of petrol on turbo-diesel engines.
An AMG version is also planned that is expected to use the 537 bhp twin-turbo 5.5 litre V8. Additional engine options are likely to include a twin-turbo 4.6-liter V8 with 435 PS (320 kW / 429 HP) and a 3.0-liter turbo-diesel with up to 258 PS (190 kW / 255 HP).
Special thanks to Andrus and Gmotors for the tip.
The Mercedes-Benz G-Class has taken a double victory in the “2011 Off-Road Vehicle of the Year” reader survey conducted by “Off Road”. Not only did the off-road legend secure first place in the “Luxury off-road vehicle” category, it also emerged in first place in the “Classic” category. In the “Special vehicles” category, the multi-talented and much adored Unimog succeeded in making its way to the top of the winner’s podium. This reader vote of confidence serves to highlight the exceptional position enjoyed by premium brand Mercedes-Benz in the all-wheel vehicle sector.
The longest-serving Mercedes-Benz model series has enjoyed superstar status for some time now: this year marks the eighth time that the G-Class, which has been in production for almost 32 years, has emerged victorious in the important reader survey conducted by specialist publication “Off Road”. As a result it has once again proved worthy of the title “off-road vehicle of the year”.
The “G” family currently has three body variants: short-wheelbase Station Wagon, long-wheelbase Station Wagon and Convertible, which can be combined with either a particularly environmentally-friendly V6 diesel engine featuring BlueTEC technology and with an output of 155 kW (210 hp) and 540 Nm of torque, or a powerful 5.5-litre V8 petrol engine developing 285 kW (388 hp) with a torque of 530 Nm. The flagship G 55 AMG model – available only as a four-door, long-wheelbase Station Wagon – is powered by a V8 supercharged engine developing 373 kW (507 hp) with an impressive peak torque of 700 Nm.
The evergreen Mercedes-Benz off-roader continues to offer a superior synthesis of high-performance drive and dynamic handling control systems. The standard specification includes the electronically controlled traction system 4ETS, the Electronic Stability Program ESP® and three differential locks selectable at the push of a button, alongside the permanent all-wheel drive with off-road ratio and the 7G-TRONIC seven-speed automatic transmission.
The G-Class Professional, which was crowned victor in the “Classic” category, is characterised by versatility, ruggedness and reliability. It has been the choice of professionals for extreme applications – such as the police and fire services for example – for almost three decades. This limited-equipment utility variant of the classic G-Class model is also often chosen by private individuals for extreme off-road applications.
When it came to special vehicles – all-terrain vehicles which are used to transport loads and goods in remote areas or which form the basis for special bodies – the Unimog was once again able to secure its place on the winner’s podium. It was praised for its design, which combines outstanding all-terrain capability with extreme ruggedness.
The first awards received by the off-road classic date back almost as far as the date of creation of the G-Class itself. In 1983 for example, the Australian specialist magazine “Bushdriver” voted it the best 4×4 off-road vehicle of the year. Since that time the off-road icon has picked up numerous additional awards. Readers of the specialist publication “auto motor und sport” alone have voted the G-Class as the world’s best off-road vehicle on no less than 14 occasions. As such the G-Class is one of the most popular and highly decorated models in the off-road vehicle sector.
The armed forces vehicle fleet service (BwFPS) took delivery of its 650th Unimog U 5000 right on time as the year comes to a close. The head of procurement at BwFuhrparkService GmbH, Uwe Günther, accepted the symbolic Unimog U 5000 keys from Michael Diez, head of government sales in the Mercedes-Benz sales organisation for Germany. Unimog deliveries are distributed to the appropriate armed forces locations in Germany and the logistics office via the mobility centres of BwFPS. The Unimog has a long tradition with the armed forces, starting in 1956 with the Unimog S and successfully continuing with tens of thousands of vehicles delivered right up to the present day.
The all-terrain Unimog U 5000 for the armed forces vehicle fleet service
A legendary vehicle with unsurpassed versatility, the Unimog U 5000 is a representative of the all-terrain Unimog series for difficult assignments far from the roads and beaten track. The Unimog is the most capable all-terrain vehicle in the gross vehicle weight class between 7.5 t and 12.5 t. Thanks to its outstanding suspension and running-gear, the Unimog is ideal for extremely tough off-road requirements and various military assignments.
The Unimog U 5000 for the German armed forces vehicle fleet service is supplied in the version with a long 3850 mm wheelbase. It is powered by the Mercedes-Benz OM 924 LA diesel engine developing 160 kW (218 hp) in the Euro-5 version.
The all-terrain Unimog U 5000 owes its high torsional flexibility to a flexible frame design incorporating two U-section side members with welded tubular cross-members. Standard equipment includes portal axles at the front and rear with differential locks, wheel hub drive, wishbones, a torque tube, coil springs, telescopic shock absorbers and stabilisers at the front and rear. The portal axles and the cranked frame with a diagonal torsional flexibility of up to 600 mm ensure a high ground clearance with a low centre of gravity at all times, while keeping all the wheels on the ground. The long travel of the coil springs allow even hazardous cargo to be safely transported over the most difficult terrain without damage. With a torque distribution of 50/50 between the front and rear axles, the vehicle is able to manage uphill/downhill gradients of up to 100% and an angle of inclination up to 38° without difficulty.
The all-terrain Unimog chassis of the U 5000 combines traditional Unimog attributes such as solidity, robustness, durability, reliability and an almost legendary all-wheel drive concept with the very latest engine and transmission technology and ergonomics at the highest level. The modernised all-steel cab with a roof hatch is also available as a crewcab. Like the engine, transmission, platform and body it has three mounting points, compensating every vehicle movement.
Bodybuilder Sonntag produces the non-distorting BwFPS standard platform
Mercedes-Benz supplies the Unimog chassis for the 650 Unimog U 5000 units. The bodybuilder Sonntag in Lennestadt, a longstanding partner of Mercedes-Benz Special Trucks and a development partner for bodies, produces the standard BwFPS platform and is responsible for the vehicle body. Both companies, Mercedes-Benz and Sonntag, have cooperated very successfully in completing this project for the German armed forces. The bodies are not rigidly bolted in place, but rather have a deformation-free connection with the frame made possible by a double mounting at three points. The BwFPS vehicle has a 4-point Twistlock demounting system which makes rapid body exchange possible.

There are quite a number of automotive legends – most of them already covered by the dust of history, not so the Mercedes-Benz Unimog. Launched during the hard times immediately after the end of World War II, the indestructible Unimog has long since become one of the living legends in automotive engineering. The Unimog holds its ground in the face of assignments under the most arduous conditions, changing economic settings and changing customer groups. Small wonder: the Unimog copes with extremely difficult ground, pulls complete goods trains, can be used as a road/railer and features attachment points for a large variety of implements.
Hard-working jack-of-all-trades right from the start
The Unimog has proved itself as a hard-working jack-of-all-trades anywhere in the world for many decades. What has remained is its basic design concept: enormous versatility for assignments of virtually all kinds, superior off-road mobility thanks to its all-wheel drive, portal gear axles and differential locks front and rear, a compact cab, outstanding robustness and the possibility of attaching a multitude of working implements.
First drafts as early as 1945
The first drafts of an agricultural vehicle, made by Albert Friedrich who had previously been Head of Aeroengine Design at Daimler-Benz, date back to the autumn of 1945. Friedrich assembled a committed team of development engineers and won over Messrs. Erhard & Sons in Göppingen, Germany, as development partners. Large-scale production began in 1948 at the mechanical engineering factory of Messrs. Boehringer in Schwäbisch Gmünd. Since high investments had to be made to reach economically viable production volumes, the project was taken over by Daimler-Benz in the autumn of 1950 – production in the Gaggenau plant started in 1951.
From 1953, the Unimog was decorated with the Mercedes star; in the same year, a fully enclosed cab complemented the previous version with folding top. Two years later, the Unimog S set out on its impressive career: it was soon highly popular among armed forces and, later on, also among civilian users, particularly among globetrotters and members of expedition. Produced until 1980, it became the bestseller in Unimog history.
Additional series to meet rising demands
As requirements became more demanding and diversified, Daimler-Benz expanded the Unimog range by the larger 406 series from 1963. In 1972, Daimler-Benz resumed the original idea of an agricultural vehicle – and for many years, the Unimog was joined by the MB-trac agricultural tractor. Only two years later, the first units from the 425 series – heavy-duty Unimogs for particularly demanding tractor work – came off the assembly lines.
From 1985, Daimler-Benz replaced the entire Unimog range in several steps. A few years later, the top-of-the-range Unimog U 2450 L 6×6 was launched, a three-axle vehicle with an impressive engine output of 177 kW (240 hp). From 1992, the company offered the new lightweight and medium-duty 408 and 419 series, which were particularly suitable for municipal work. Shortly afterwards, the Funmog – a conspicuously designed and elegantly equipped Unimog, which also cut a fine figure outside the disco in the evening – assumed the status of a cult vehicle. The small UX 100, a compact implement carrier, predominantly appealed to municipal authorities from 1996.
Into the future with the new U 300 – U 500 series
The new Unimog U 300, U 400 und U 500 available since 2000 are also tailored to municipal work. The vehicles combine spectacular looks with a practical as well as attractively designed cab made of fibre composite materials, a driver’s workplace called VarioPilot that can be moved from left to right and back again within seconds, a new VarioPower high-performance hydraulic system and engines with output ratings up to 205 kW (280 hp) – the new Unimog for the new millennium can do even more than any of its predecessors and meets the most diverse demands of a heterogeneous clientele.
Complete Unimog range
In the early sixties, the small basic Unimog alone was no longer capable of meeting the growing demands and covering the ever more diversified range of assignments. The Unimog S, first and foremost a military vehicle, was not always the right alternative for civilian applications, even though it was available in finishes other than olive green. Therefore, the company launched a medium-duty series with the designation 406 in 1963. The wheelbase of this new, additional Mercedes-Benz Unimog was 2380 millimetres long.
Opening up new dimensions: the 406 series
At the same time, larger diesel engines were for the first time installed under the Unimog’s short bonnet: 65 hp generated from four cylinders and a little later even from the legendary, large-volume OM 312 six-cylinder diesel engine with a displacement of 5.7 litres – setting a new standard in performance. With reference to its hp rating, the new Unimog became known as the U 65. With the additional 406 series, Daimler-Benz complemented the Unimog range by a genuine jack-of-all-trades for use on and off the road, permitting completely new applications, for instance as a versatile tractor.
406 series rapidly joined by additional model series
In 1966, the company restructured the Unimog range. The small Mercedes-Benz Unimog U 34 was joined by the medium-duty 406 series with the U 70 model, which, at a later stage, developed into the U 80 and U 84 as engine output increased – figures relating to engine output in hp in each case. Parallel to this, Daimler-Benz introduced the 416 series with 2900 millimetre wheelbase corresponding to the Unimog S. The series initially consisted of the U 80 which developed over the years into U 90, U 100 and finally into the powerful U 110.
In addition, Daimler-Benz introduced the lightweight 421/403 series, complemented at a later stage by the 413 series, to fill the gap between the original Unimog and the medium-duty series. These new series differed in terms of their wheelbase lengths and their engines, which were adopted from the car range (421 series/U 40 with 2.2 litre displacement) as well as from the commercial vehicle range (403 series/U 54 with 3.8 litre displacement). The output ratings of these models, too, rose continuously until the renewal of the range in 1977.
Unimog complemented by a specialist farm tractor: the MB-trac
This rapid progress in model policy, which may not have been easily comprehensible at all times, resulted in another anniversary: production of the 100,000th Unimog in May 1966. During its career over almost 20 years, the Unimog had developed magnificently ever since the days the first chassis prototype had been completed. It had long since acquired a legendary offroader reputation throughout the world. As successful as the Unimog may have been, it was only rarely used in agriculture. To cover this market segment, Daimler-Benz therefore launched an additional vehicle in 1972: the MB-trac.
The new agricultural tractor combined Unimog engineering, including all-wheel drive and power transmission to four equal-sized wheels, with the looks of a tractor: a long and very narrow bonnet and behind it an angular, high-rising driver’s cab. Contrary to conventional tractors, however, the cab was located between the axles and fully enclosed.
Within just a few years, the initial MB-trac 65 and MB-trac 70 (later 700) models developed into a broad series right up to the extremely powerful MB-trac 1500. In spite of this, the MB-trac failed to become a great hit. Daimler-Benz eventually integrated the MB-trac in a joint venture with the agricultural machinery unit of Deutz. Production of the MB-trac was discontinued in 1991.
425 series: the new, big Unimog
The next new Unimog series emerged in 1974, two years after the MB-trac. Large-scale production began in 1975: the U 120 from the 425 series was the heavy-duty top model in the range of versatile tractors and working machines from Daimler-Benz. Its conspicuous features included a new, angular cab and a large bonnet set at a flat angle. The latter ended in a large-surfaced, black radiator grille. This cab design has basically remained unchanged for the last 25 years.
The 425 series initially included a 120 hp model (boosted shortly afterwards to 125 hp in the U 125) with 2810 millimetre wheelbase and a permissible gross weight of nine tonnes. Also in 1975, production of the 435 series as the successor to the Unimog S began for the German armed forces; these vehicles had wheelbase lengths of 3250, 3700 or even 3850 millimetres. From 1976, the 424 series fitted into the range somewhat further down below.
New model designations to create a clear structure
At about the same time, Daimler-Benz introduced new model designations. The models with the rounded, meanwhile classic shapes were the Mercedes-Benz Unimog U 600/L, U 800/L, U 900 and U 1100/L. New angular shapes were the hallmark of the Unimog U 1000, U 1300/L, U 1500 and the flagship, the U 1700/L with 124 kW (168 hp) engine. The letter “L” indicated the long-wheelbase version – the majority of models were meanwhile available in two wheelbase lengths.
The Unimogs with rounded cabs belonged to the lightweight series, the new models with angular cabs made up the medium-duty and heavy-duty series, the division being made on the grounds of permissible gross weight. Several engines were available for different series – the Unimog designation system was not easy to understand. And finally, the range was still complemented, though in declining numbers, by the tried-and-tested Unimog S, the only one with a petrol engine.
Disc brakes in Unimogs long before their introduction in trucks
Clearly more easily understandable were the technical highlights: with the exception of the bottom-of-the-range model, all Mercedes-Benz Unimogs were fitted with disc brakes all round at the time the new model designations were introduced – long before this safety equipment became state of the art in trucks. The efforts of the Unimog people to give every customer the model he or she needed paid off in the form of another record figure: in 1977, the 200,000th Unimog was produced.
Complete renewal with the 407, 417 and 427 series
In the following years, the Unimog range remained largely constant. But then, between 1985 and 1988, new models were again launched one after the other: Daimler-Benz completely replaced the entire range by the 407, 417, 427 and 437 series. The cab from the medium-duty and heavy-duty series was now also used for the lightweight models. New wheelbase lengths, dimensions, weights, chassis and engines under the cabs’ sheet metal skins resulted in completely new vehicles.
After this renewal, the range was larger than ever before, extending from the lightweight, particularly easily manoeuvrable Mercedes-Benz Unimog U 600 with an output of 44 kW (60 hp) and a gross weight of 4.5 tonnes via countless versions – the result of further expansion in the early nineties – to the three-axle U 2400. Its engine developed a new record output of 177 kW (240 hp) from a displacement of six litres. The two-axle version’s permissible gross weight was 14 tonnes.
Output increased almost tenfold since the beginning
From 1993, the range was rounded off at the top end by the Unimog U 2450 L 6×6, a three-axle unit with all-wheel drive. The people who had developed the first Unimog more than 40 years earlier would certainly not have dared dreaming of such models – if anything, a comparison of engine output is worth its while: from the first Unimog to the new top model, it had increased almost tenfold.
Completely new series for new customers
Shortly after the renewal of the Unimog range between 1985 and 1988, Daimler-Benz started a new innovation drive in 1992. New lightweight and medium-duty series, the 408 (U 90) and 418 (U 110, U 140), replaced their still rather youthful predecessors. Their most conspicuous feature was the completely redesigned cab, with a front section set at a very steep angle to provide the driver with an excellent view of the area ahead of the vehicle. On request, the bonnet even featured an asymmetrical cutaway section on the driver’s side, permitting the best possible view of connections and mounted implements. The Unimog’s handling and ride were improved by a new frame and progressively acting coil springs.
The tried-and-tested ladder-type frame was retained, with tubular cross members welded into the longitudinal members. This design of frame allowed for extreme torsion, yet the ensemble as a whole was remarkably rigid. In conjunction with the suspension, therefore, it offered excellent offroad wheel-load distribution. At the same time, whether laden or unladen, the progressively acting coil springs provided constant and optimally adjusted suspension quality. In addition, the rear telescopic shock absorbers operated using a load- and path-dependent characteristic curve, resulting in reduced damping of the vehicle when empty.
Clearly more space, comfort and practicality
The completely redesigned cab with its raised roof provided substantially more space than before, clearly laid out controls and, not least, an appealing working environment. The new Mercedes-Benz Unimog’s special technical features included a tyre pressure control system that could be operated on the move, the anti-lock braking system, new engines from the car range for the lightweight U 90 as well as Servolock, a unit for hydraulically locking working implements. The new Unimog generation not only expressed individuality and great practicality in its looks, with its diversified range of applications, it also recommended itself for an ever more important group of buyers: municipal authorities.
Pulling up outside the disco in the Funmog
A very different group of customers emerged temporarily: the Mercedes-Benz Unimog had been discovered as a disco-mobile in Japan – the old battlehorse with its advanced engineering, a died-in-the-wool commercial vehicle, was all of a sudden a big hit among youngsters. Daimler-Benz reacted by launching Funmogs, an impressive, pitch-black Unimog from the heavy-duty series and a red-metallic one from the new medium-duty series. Both featured plenty of chrome trim. The attractive Funmogs promptly won the “Offroader of the Year” award in the spring of 1994. The indestructible nature of the evergreen from Gaggenau was also reflected by the production figures: in the same year, Unimog production exceeded the 300,000 mark – a very high figure for a special-purpose vehicle.
UX100 – the little one for municipal authorities
Two years later, in 1996, Daimler-Benz 1996 expanded the range by the addition of an implement carrier for municipal authorities, the UX100. This small Unimog was a slim and easily manoeuvrable vehicle, suitable for work on walkways and in parks. However, the Unimog’s little brother did not generate big business. Within the framework of its concentration on core competencies, Daimler-Benz transferred the smart UX100 to Hako, a company specialising on vehicles of this type and size. Nevertheless, the Unimog engineers adopted quite a few ideas from the UX100 project for future vehicles.
Spectacular: Unimog U 300, U 400 and U 500
The company had meanwhile been preparing for another renewal of the Mercedes-Benz Unimog range. In the spring of the spectacular year 2000, the company presented new, equally spectacular Unimog models: the U 300, U 400 and, a little later, the U 500 (408/418 series) replaced the previous medium-duty and heavy-duty series. With this model replacement, the Unimog received more advanced technology in one go than ever before in its long career. A particularly conspicuous feature is the highly advanced, practical and at the same time extremely appealing cab made of fibre composites. The huge windscreen extends far down, permitting a perfect view of all connections and implements – the latter can now be mounted effortlessly in one-man operation.
Engine fitted between the axles
The bonnet is extremely short because the engine has been moved backwards to a location between the axles. You could say that this Unimog incorporates an idea of its inventor, Albert Friedrich, who had sketched in the engine in a similar position in one of his first drawings in 1946.
VarioPilot: moving the driver’s place to the other side
The all-new cab incorporates not only plenty of space and highly comfortable appointments but also an idea the engineers adopted from the UX100 project and refined it: the driver’s workplace, complete with steering wheel, gauges and pedals can be moved from the left to the right-hand side and back in next to no time. What sells under the name VarioPilot proves to be an extremely practical feature for the different applications in municipal work. A broad range with wheelbase lengths between 3080 and 3900 millimetres and permissible gross weights from 7.5 to 15.5 tonnes underlines the Unimog’s flexibility and performance more than ever before. For special applications, for instance tractor operation, the Mercedes-Benz Unimog is available with special equipment, including a torque converter and clutch unit or remote control with cable.
New emphasis: implement carrier for municipal work
Both the design of the new Mercedes-Benz Unimog and its features underline that it is clearly oriented to the spectrum of the 408/418 series. It is still a near-perfect offroader, but its emphasis is on implement carrier work. Other features of the new Unimog: permanent all-wheel drive, electro-pneumatic Telligent gearshift, the new VarioPower high-performance hydraulic system and new, extremely powerful engines with output ratings between 110 kW (150 hp) and 205 kW (280 hp) and complying with the EURO 3 emission standards. And those still looking for a classic Mercedes-Benz Unimog with a focus on extreme off-road capabilities will continue to be served for the time being by current model series.
All we have still have some time to wait before the 2012 Mercedes ML63 AMG makes its official debut, spy photographers have captured photos of the model undergoing a bit of track testing on the infamous Nurburgring. While heavy masking still hides much of the SUV’s styling cues, under the hood we can expect Mercedes-AMG’s new twin-turbo V8 that produces 536 horsepower and 590 lb.-ft. of torque. There’s also talk of the AMG Performance Package making its way onto the next ML63 AMG, which if true, would boost output to 563 hp (420 kW, 571 PS) and up to 900 Nm (664 lb-ft) of torque.
We’ll keep you posted as new details of the 2012 Mercedes-Benz ML63 AMG are released in advance of its likely premier at the 2011 Frankfurt Motor Show. In the meantime, check out more 2011 ML63 AMG spy photos in the gallery below, then head over to World Car Fans for the full article.
