Special-protection variant Mercedes-Benz M-Class Guard: High-level protection in SUV

Don't Copy From This Blog...

The new special-protection variant of the M-Class is the latest addition to the extensive Mercedes-Benz Guard family. As with all Guard models, the armoured version of this popular SUV follows the brand-typical integrated special protection design principle. All the additional protection systems are taken fully into account right from the development phase of each model series and perfectly integrated into the vehicle's architecture. This enables all the advantages of the standard series-production vehicle to be retained, such as for instance the luxurious yet functional vehicle interior, the high level of active and passive safety, the exceptional ride comfort and the agile driving dynamics.

As with all special-protection vehicles with the three-pointed star, in the new M-Guard the focus is on a holistic development approach: integrated special protection. This means that the individual protection elements are integrated in the raw vehicle bodyshell from scratch in an autonomous process, by virtue of which the entire passenger compartment receives a kind of coat of armour that even includes elements such as the roof frame struts, locks, door gaps and exterior mirror mounts. This way, a Mercedes-typical comprehensive protection system against ballistic attacks is created, providing protection that includes places where retrofitting would hardly be possible, or would be much less effective.

Another advantage of the integrated protection concept over retrofits that burden the vehicle body structure with added weight: right from the outset the vehicle bodyshell is strengthened in accordance with the greater weight and the positioning of the armour elements. This results in a greater stability of the entire body structure and consequently in the typical longevity and high resistance characteristic of the conventional M-Class models.

M-Class Guard: all-round protection

The bodyshell of the M-Class goes through all the stages of large-series production, benefiting from the excellent quality of the M-Class bodyshell. Unlike its standard series-production counterpart, though, the Guard bodyshell has specific adaptations for the attachment of the armour elements, a front structure with reinforcing elements and modified doors. The armour itself includes:

- Windows of the highest optical quality Special laminated glazing with a uniform thickness all-round, polycarbonate layer on inside to protect against shards.

- In the un-transparent sectors perfectly tight-fitting formed special steel is used throughout. In the A-, B- and C- pillars and the firewall and roof, this steel also reinforces the passenger compartment and increases structural firmness.

- All the components installed comply with defined ballistic requirements, are subjected to constant ballistic control and are already correspondingly certified beforehand.

Complies with VR 4 protection class

The new M-Guard meets the requirements of protection level VR4 according to testing guidelines BRV 2009 for special-protection vehicles with bullet resistance (according to Bullet Resistant Vehicles 2009). This ballistic classification designates ballistic resistance (VR = Vehicle Resistance) in terms of the weapons and calibre: in this case, among others, Magnum .357 and .44. Certification was carried out by the Ulm-based Ballistics Bureau. This independent, neutral, test ensures that the integrated protection concept is appropriate to face the hard requirements of real danger situations. The M‑Guard passed the following ballistic and explosives tests successfully:

- Fire from different angles

- Blasts, for example with DM51 hand grenade, according to test guidelines ERV 2010. Both in the front and in the vehicle rear, these were successfully resisted by the M-Guard with the optional floor armour

Well-harmonised suspension, powerful engines

In spite of the increased weight caused by its armour, the M-Guard achieves the impressive ride comfort, great agility and extraordinary active safety of its series-production counterpart. The special-protection variant features as standard an AIRMATIC air suspension system with Adaptive Damper System (ADS) specifically adapted to the vehicle's special protection features. Stronger axle components compensate for the increased weight of the M-Guard superbly, Guard-specific torsion bars at the rear axle optimise roll behaviour in fast curves and when taking evasive action.

The M-Guard is exclusively available with tyres with run-flat capability and 5‑spoke 50.8 cm (20-inch) AMG light-alloy wheels. MOE tyres with run-flat capability make it possible to drive on safely for up to 30 km at a maximum speed of 80 km/h even if the tyre has suffered a total loss of air.

With the new ML 350 BlueTEC Guard there is a diesel power plant that is just as economical as it is agile for the first time in this segment. It offers the tried-and-tested V6-cylinder diesel engine with 190 kW output (258 hp) and a top torque level of 620 Nm. It meets the requirements of the currently strictest EURO 6 emissions standard. The V8 petrol-engine-powered ML 500 Guard with 300 kW (408 hp) and 600 Nm is available as an alternative. LHD and RHD versions of both vehicles are available.

Unrestricted interior space

The sporty character and high value appeal of the series-production vehicle are also distinctive of the generously-dimensioned interior of the M-Guard. The protection measures restrict neither the car's famed ambience of well-being nor the space available for its up to five passengers. Its load capacity of up to 2010 litres and the payload of around 560 kg are of the same high level as those of the series-production non-special protection M-Class models. In addition the M-Guard customers can choose from among most of the M-Class's attractive equipment options. Among these worthy of note are for instance exclusive leather appointments, infotainment systems, such as COMAND Online, and high-value sound systems.

Extensive trial programme for top reliability

Apart from the specific ballistic tests carried out by the Ballistics Bureau in Ulm, the M-Guard has to pass a detailed test programme just like its series-production counterparts. These trials mimic everyday operating conditions, exceeding these parameters by a large factor in many cases. They include an endurance test lasting several weeks to determine bodyshell strength, standardised simulation of arduous roads on special bodywork test rigs and road endurance tests to ensure the durability of drivetrain and suspension under extreme conditions. Over and above these trials, heat and cold tests and high-speed driving on test courses are carried out to ensure the resistance of individual components and their overall operation under the greatest stresses. In a separate winter trial on ice and snow, the engineers adjust the driving dynamics systems to the increased weight due to the armour. Finally a crash test programme ensures fault-free operation of all passive protection systems.

Mercedes-Benz offers nine special-protection models

The Guard programme currently includes vehicles of the S-, E-, M- and G-Class. With a total of nine models Mercedes Benz has one of the most comprehensive special-protection ranges:

- E 350 BlueTEC Guard

- E 250 Guard*

- E 350 Guard*

- E 500 Guard

- ML 350 BlueTEC Guard

- ML 500 Guard

- G 500 Guard

*Only for certain countries

The Guard models can avail themselves of a network of Mercedes-Benz Service stations all around the world for the service, maintenance and repair work needed. And of course the special-protection models also come with a full factory warranty. The new M-Guard can be ordered as of 15 March 2013.
The prices in Germany (in addition statutory 19% VAT):

- ML 350 BlueTEC Guard €105,050

- ML 500 Guard €118,650

Five Stars for Mercedes-Benz: C-Class and M-Class get top marks in more stringent US crash test

Don't Copy From This Blog...

Since the American crash test program US NCAP was made more stringent in 2010, only a few vehicles have achieved the highest assessment with five stars. These elite vehicles include the Mercedes-Benz C-Class and M-Class. These both also achieved top marks in the European Euro NCAP rating and in the test by the American Insurance Institute for Highway Safety (IIHS), thereby confidently mastering three of the most challenging international safety ratings. This underlines Mercedes-Benz's exceptional position as a pioneer in safety and a technical trendsetter.

The manufacturer-independent US NCAP rating (US New Car Assessment Program) is similar to its European counterpart Euro NCAP in many regards. However, the US program significantly tightened up many of the requirements in 2010, also including additional tests in the rating. This resulted in a dramatic decrease in the number of five-star results. The Mercedes-Benz C-Class and M-Class are among the few vehicles to have achieved the top result of five stars according to the new criteria which are based on real-life accident scenarios.

Unlike the Euro NCAP, the updated US rating uses a significantly heavier deformable barrier (1368 kg compared with 950 kg) for the side collision in order to comply with the increased average weight of modern American vehicles. Another example: A rigid barrier is constructed for the frontal collision instead of a deformable barrier. The vehicle also hits the barrier with a full overlap (40 percent in Euro NCAP). The test program has also been expanded to include a lateral angled pole impact.

The assessment criteria have also been made significantly more stringent. The probability of serious injury to the head (head injury criterion) and the strain on the throat, chest and femur of the driver and front passenger are evaluated. In order to get five stars, the probability of serious injury must be under five percent.

As well as in the challenging new US NCAP rating, the C-Class and M-Class also achieved five-star results in the Euro NCAP, just like all Mercedes-Benz passenger cars have for many years. The American Insurance Institute for Highway Safety (IIHS), a private organisation led by various commercial vehicle insurance companies, also declared both Mercedes-Benz model series to be "Top Safety Picks" thanks to their outstanding test results.

Mercedes-Benz believes these national and international safety ratings to be very sensible. However, the safety experts for the premium brand with the three-pointed star will not settle for merely achieving rating targets; instead they work constantly and intensively on achieving a level of safety that exceeds the standards required by all the legislation worldwide. Actual accident scenarios are therefore an important benchmark for their work. This is why they have been investigating thousands of specific accidents for several years. On this incorruptible basis, Mercedes-Benz has developed a safety concept which not only aims to prevent accidents but also minimize the consequences of them. The experts call the result of their work "Real Life Safety".

Based on this comprehensive safety philosophy, Mercedes-Benz has developed or initiated several modern safety systems that effectively support drivers. One example is the occupant protection system PRE-SAFE®, launched ten years ago. It can activate safety measures for the passengers as a precaution, even before an impending crash. The aim is to prepare the occupants and the vehicle for an imminent collision, by, for example, ensuring that the seat belts and airbags can implement their full protective effect during an impact. PRE-SAFE® is now available in 14 model series right across the Mercedes-Benz model range.

As another indicator of its power of innovation when it comes to occupant protection, Mercedes is further expanding its protection for rear seat passengers with the active belt buckle and the beltbag. An electric motor automatically moves the belt buckle up and down as part of the active belt buckle. This allows belt slack in the pelvis and thorax regions to be reduced and passengers are better secured both laterally and longitudinally. The beltbag is an inflatable belt strap which can reduce the risk of injury to rear-seat passengers in the event of a frontal collision by reducing the forces exerted on the rib cage.

The "Real Life Safety" holistic approach pursued by accident researchers at Mercedes-Benz also increasingly leads to the fusion of comfort and safety, thanks to the implementation of intelligent assistant systems which Mercedes-Benz groups together under the name "Intelligent Drive". This includes systems which could, for the first time, prevent accidents with crossing vehicles or pedestrians, as well as an active lane keeping assist system which could also prevent accidents with oncoming traffic. Anti-dazzle permanent main-beam headlamps are also in development.

Assistance systems like these are not yet generally required by vehicle safety rating systems but various institutions are already starting to request them.

Mercedes-Benz is constantly increasing the performance of these assistance systems. The aim is all-round protection, not only for the occupants of Mercedes-Benz vehicles, but also for all other road users.

AUTO TEST WINNERS in GREEN! 2013: M-Class and B-Class are the most environmentally friendly

Don't Copy From This Blog...

The renowned German environmental research institute "ÖkoTrend" has ascertained that the Mercedes-Benz ML 250 BlueTEC 4MATIC and Mercedes-Benz B 200 Natural Gas Drive are the most eco- friendly cars in their class. Both models have thus now been honoured as "Winners in Green" by the magazine AUTO TEST.

The independent research institute "ÖkoTrend" in Germany has been analysing and evaluating products according to ecological criteria and in terms of the social and environmental responsibility of their manufacturers since 1995. The environmental car ranking, published annually, is always awaited with great interest. The environmental credentials of a broad range of cars are thoroughly assessed in twelve different categories on the basis of extensive data accumulated by the Institute. The categories include fuel consumption, pollutant emissions, manufacturing, logistics, recycling and the environmental management system operated by the manufacturer.

For the second consecutive time, the top spot among the SUVs has been taken by the Mercedes-Benz ML 250 BlueTEC 4MATIC. When it came to the compact MPVs, first place also went to a Mercedes-Benz – the B 200 Natural Gas Drive. Specialist journal AUTO TEST has therefore honoured both cars with the title of "AUTO TEST WINNER in GREEN! 2013".

The Mercedes-Benz ML 250 BlueTEC 4MATIC owes its top ranking among the SUVs to, amongst other things, its state-of-the-art four-cylinder diesel engine, which features both direct injection and turbocharging. From a displacement of 2143 cc the car delivers an output of 150 kW (204 hp) and impressive torque of 500 Newton metres. This allows it to accelerate from 0 to 100 km/h in 9 seconds and to use a mere 6 litres of fuel per 100 kilometres, while emitting just 158 g/km of CO2 (combined). It is therefore able to travel a distance of up to 1500 kilometres without the need for refuelling. The Mercedes-Benz B 200 Natural Gas Drive operates on the basis of Monovalent+. This means that the engine runs as a general rule on natural gas, but that the vehicle also has a small, 12‑litre petrol tank on board to cope with any emergencies. Should the natural gas tank at any point run empty, the vehicle will switch automatically and imperceptibly to run on petrol.

Thanks to its natural gas drive system, the CO2 emissions of the 115 kW (156 hp) engine in the B 200 Natural Gas Drive have been reduced by more than 16 percent. Furthermore its exhaust gas emissions are significantly cleaner than those of a vehicle running on petrol or diesel, while the fuel costs are around 50 percent lower than for the equivalent petrol-engine model.
Because the driver is not able to actively select the petrol operating mode, the B 200 natural Gas Drive is certified as a natural gas vehicle and thus able to benefit from tax incentives. The range of the vehicle in natural gas operating mode is around 500 kilometres.

Dr. Dieter Zetsche hands over Mercedes-Benz M-Class in Rome: New Popemobile from Mercedes-Benz for Pope Benedict XVI

Don't Copy From This Blog...

By delivering a new Popemobile to Pope Benedict XVI Mercedes-Benz continues a tradition, which lasts for 80 years now. Dr Dieter Zetsche, Chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz Cars, personally handed over the Mercedes-Benz M-Class, specifically produced for the Pope with special-purpose body, today at the Vatican.

"It is an honour for Mercedes-Benz to be accompanying His Holiness Pope Benedict XVI on his future journeys with our new Popemobile", said Zetsche at the handover of the new Popemobile in Rome. "As such, we are continuing our long-standing partnership with the Vatican. For more than 80 years now, Popes have been able to rely on the quality, safety and comfort of our Mercedes-Benz vehicles."

The leader of the Catholic Church makes use of the Mercedes-Benz Popemobile at a number of public appearances both at home and abroad. It gives him the opportunity to get as close as possible to the public without having to forego the highest possible levels of safety and comfort. It will be possible to see Benedict XVI tomorrow in the new vehicle for the first time as early as 8th December in Rome, where the Catholic Feast Day of the Immaculate Conception is traditionally celebrated at the Spanish Steps.

The Popemobile is fitted with the latest technological highlights from the current M-Class. In addition, the vehicle also features a new interior design. Compared with the preceding model, the dome has been extended significantly, providing an improved amount of space and more convenient entry access. The view of the Pope has also been significantly enhanced thanks to considerably larger glass panels in the viewing area, together with large illuminated roof lining. The throne, the central design feature in the interior, bears the embroidered coat of arms of the Holy Father.

As with the preceding model, the body of the new Popemobile is painted in diamond white. And to facilitate frequent transport of the modified M-Class by air, Mercedes-Benz has reduced the overall height of the vehicle by a few centimetres, while at the same time improving the internal standing height. Work on the new Popemobile began some nine months ago. The vehicle was designed and produced by Mercedes-Benz.

Mercedes-Benz has been providing vehicles for the trips and official appearances of the leader of the Catholic Church for more than 80 years now. The first Mercedes-Benz for a Pope was a Nürburg 460 Pullman Saloon, provided for Pope Pius XI in 1930. In the 1960s, Pope John XXIII received a 300d Landaulet in the guise of a Cabriolet with automatic transmission. Subsequently, Pope Paul VI first made use of a Mercedes-Benz 600 Pullman Landaulet, followed by a 300 SEL.

From the 1980s, Pope John Paul II initially also travelled in a vehicle designated as a "Popemobile" - a modified G-Class - to the celebrations in St. Peter's Square. From 2002, he mostly made use of the predecessor to the new Popemobile, which Benedict XVI has also used up until today. After they reach the end of their working lives, the Popemobiles can be viewed as part of the collections on display at both the Vatican and the Mercedes-Benz Museum in Stuttgart.

World debut at the 2012 Essen Motor Show: The BRABUS Tuning Program for the Mercedes-Benz M-Class (W 166)

Don't Copy From This Blog...

Exclusive, individual and ecofriendly strong in compliance with EURO VI emission standards: these three attributes best describe the latest BRABUS tuning program for the Mercedes W 166-series M-Class. From a visual standpoint the SUV receives an upgrade with a sporty yet elegant aerodynamic-enhancement program and custom-tailored BRABUS Monoblock wheels with diameters of up to 22 inches. The program also includes engine tuning for the ML 350 BlueTEC 4MATIC that is as powerful as it is ecofriendly. Further on offer are stainless-steel sport exhaust systems for all models and striking interior designs including an all-leather interior in any desired color. BRABUS backs all components with the one-of-a-kind BRABUS Tuning Warranty® of three years, up to 100,000 kilometers/62,000 miles.

To give the current M-Class a more customized and exclusive look BRABUS offers an innovative and striking appearance package. The front bumper of the sport version can receive some added profile with the BRABUS ‘On Road’ front spoiler and attachments for the air inlets in the front fascia.

To give the new 4x4 seemingly a longer, sleeker stance the BRABUS designers have developed new sill skirts. They combine elegant design with a safety feature: entrance lights integrated into the underside are activated by pulling on a door handle or by pushing the unlock button on the keyless remote. This also activates the BRABUS logo optionally integrated into the sill skirts and the BRABUS lettering in the fender attachments that are a new development as well.

The rear end of the M-Class is upgraded with the BRABUS ‘On Road’ rear fascia that is available in two versions. Depending on the type of engine the rear fascia comes with a cutout on the left or with a cutout on either side to provide the perfect backdrop for the BRABUS dual or quad sport exhaust system. A BRABUS rear spoiler that attaches to the liftgate is available as well. In addition, there is a BRABUS WIDESTAR wide-body version complete with fender flares. The entire appearance package is manufactured in OEM quality from high-grade Pur-R-Rim plastics.

The exclusive looks are also characterized by the custom-tailored BRABUS Monoblock wheels with diameters ranging from 18 to 22 inches. The largest version BRABUS offers for the new M-Class features king-size 10Jx22 wheels. The cast wheels are available in five different designs as Monoblock VI, E, Q, R and S wheels. As an alternative BRABUS offers the Monoblock G "Platinum Edition" forged wheels in the same size. State-of-the-art forging technology makes these wheels with five double spokes the perfect symbiosis of low weight and maximum strength. BRABUS technology partners Continental, Pirelli or YOKOHAMA supply suitable high-performance tires up to size 295/30 ZR 22 front and back for all BRABUS wheels.

The BRABUS suspension components, developed in cooperation with BILSTEIN, are specifically calibrated to this tire/wheel combination. For vehicles with conventional steel suspension BRABUS offers a choice of sport springs for a ride-height lowering by some 30 millimeters (1.2 inches) or a sporty yet comfortable sport suspension. For M-Class vehicles with AIRMATIC air suspension the BRABUS suspension engineers have developed a custom control module that lowers the ride height of the SUV by some 30 – 40 millimeters (1.2 – 1.6 inches).

For further optimizing the off roader’s already impressive active safety BRABUS offers a high-performance brake system. The front axle combines six-piston fixed aluminum calipers with vented and cross-drilled discs measuring 405 x 34 millimeters (16 x 1.3 inches). Together with four-piston fixed aluminum calipers and brake discs measuring 380 x 28 mm (15 x 1.1 inches) on the rear axle the brake system provides stopping power normally reserved for purebred sports cars. The BRABUS system also delivers maximum fade-free endurance.

BRABUS offers the world’s most extensive program of engine tuning for Mercedes-Benz automobiles and so it is no wonder that the program was also adapted to the new M-Class. For the V6 common-rail turbodiesel engine of the ML 350 BlueTEC 4MATIC the BRABUS engine specialists have developed the BRABUS ECO PowerXtra D6S performance kit that falls into the same EURO VI emissions class as the production car.

The engineers developed the BRABUS ECO PowerXtra D6S module for the direct-injection engine in the BRABUS engine development department using state-of-the-art test bench technology and a cutting-edge emissions lab. The plug-and-play auxiliary control unit is integrated into the CAN bus of the SUV. The BRABUS mapping was calibrated specifically to the ecofriendly BlueTEC concept that uses AdBlue® reactant for emission control.

The BRABUS ECO PowerXtra D6S performance kit bumps peak torque from standard 620 Nm to 690 Nm (457 to 509 lb-ft), available on a plateau between 1,600 and 2,400 rpm. At the same time maximum power output jumps from 190 kW / 258 hp (254 bhp) to 227 kW / 309 hp (304 bhp) at a low 3,600 rpm.

Performance with BRABUS D6S tuning improves enormously: with a sprint time of just 6.0 seconds the SUV takes exactly 1.4 seconds less for the sprint from 0 to 100 km/h (62 mph) than the production car. Top speed increases to 229 km/h (142 mph).

Additional versions of BRABUS engine tuning are available for the other M-Class engines. All BRABUS engines are lubricated exclusively with MOTUL high-performance motor oil. Custom-calibrated stainless-steel sport exhaust systems with two or four distinctive BRABUS tailpipes are available for all M-Class engines.

Yet another particular BRABUS specialty are exclusive interior options for the new M-Class: bi-color stainless-steel scuff plates with backlit BRABUS logo as well as matte-anodized aluminum pedals, door-lock pins and foot rest are part of the refinement repertoire as are exclusive BRABUS interiors masterfully crafted from a combination of the finest Mastik leather and Alcantara. In addition, there are exotic-wood and carbon-fiber trim sets in any desired color and with a variety of surfaces from open-pored and matte to high-gloss finishes.

New 2013MY Mercedes-Benz M-Class Debuts COLLISION PREVENTION ASSIST

Don't Copy From This Blog...

The 2013 Mercedes-Benz M-Class sport utility marks the debut of an important new safety feature – COLLISION PREVENTION ASSIST. Standard equipment on all four 2013 M-Class models, COLLISION PREVENTION ASSIST uses dedicated radar sensors to monitor the distance to a vehicle in front and to stationary objects. If the system senses a risk of imminent collision, it alerts the driver with a warning beep and flashing light on the dash. COLLISION PREVENTION ASSIST also networks with standard Brake Assist to prepare for emergency braking, so that as soon as the driver applies the brakes, maximum power assist can be applied. In addition, the new system can recognize and adapt its response to a number of driving conditions such as bumper-to-bumper traffic.

Four M-Class Models for 2013

The third generation of a highly successful Mercedes-Benz that began the industry trend toward SUVs with a more car-like ride, the dramatically styled 2013 M-Class is instantly recognizable as a sport utility vehicle. With its large wheel openings and "two-box" profile of its nose and cabin, this eye-catching interpretation of a modern SUV makes a strong presence that projects trend-setting design and quality.

The M-Class line for 2013 is comprised of four models, all with direct injection – the thrifty ML350 BlueTEC diesel (240 horsepower, 455 lb.-ft. of torque), the popular ML350 with its V6 gasoline engine (302 hp, 273 lb.-ft.), the biturbo V8-powered ML550 (402 hp, 443 lb.-ft.) and the high-performance ML63 AMG (518 hp, 516 lb.-ft., and 550 hp, 560 lb.-ft. with the AMG Performance Package).

4MATIC Four-Wheel Drive Sets a Trend

All four models come with proven Mercedes-Benz 4MATIC all-wheel drive (the ML350 is also available with rear-wheel drive). As modern all-wheel-drive systems become more refined, they are becoming more popular, especially in the luxury car market. With negligible weight and fuel-efficiency tradeoffs, full-time four-wheel drive provides year-round traction and stability benefits on both wet and dry roads. Fuel efficiency has been optimized, due to a number of innovative measures that minimize the energy needed to turn the extra gears and shafts.

Seven-Speed Transmission

The 2013 M-Class line is equipped with a transmission that provides even better fuel mileage, more responsive driving, quieter operation and increased durability. The latest transmission features a more advanced torque converter lock-up clutch and is designed to work best with a new type of low-viscosity ATF transmission fluid, colored blue instead of the usual red.

Together with low-drag planetary gears, bearings and internal seals, the "FE-ATF" fluid provides less friction and improved fuel mileage. Lower hydraulic pressure and enhanced electronic software helps provide even smoother shifting.

302-Horsepower V6 Engine for the ML350

With 302 horsepower and 273 lb.-ft. of torque, the 3.5-liter V6 engine is assembled in a new block with 60-degree cylinder angles, so it doesn't need a balance shaft for smooth operation. The engine features aluminum cylinder heads, pistons and cylinder block (with cast-in Silitec cylinders), as well as a crankshaft, connecting roads and valves made of special forged steel.

402-Horsepower V8 for the ML550

Based on its highly successful 5.5-liter predecessor, the 4.6-liter V8 engine has 20 percent smaller displacement but generates more power than the previous engine – 402 horsepower and 443 lb.-ft. of torque. Its smaller displacement is more than offset by the power boost of its twin turbochargers – one for each bank of cylinders. Piston crowns are thicker to handle the higher combustion pressures, while shorter connecting rods allow existing block dimensions to be retained.

518-Horsepower V8 for the ML63 AMG

AMG uses its own 5.5-liter version of the 4.6-liter Mercedes-Benz biturbo V8 that also produces more power and better fuel economy simultaneously. Replacing AMG's normally aspirated 6.3-liter V8, the smaller engine features twin turbochargers, direct fuel injection, and multi-spark ignition. Compared to the 4.6-liter biturbo, the ML63 AMG powerplant makes use of more displacement (a larger cylinder bore and longer crankshaft stroke), higher turbocharger boost, and slightly lower compression. Identified inside the company as the M157, the AMG twin-turbo V8 produces 518 horsepower and 516 lb.-ft. of torque. With the optional AMG Performance Package, these figures increase to 550 hp and 560 lb.-ft.

Direct Fuel Injection

All three gasoline engines (ML350, ML550 and ML63 AMG) make use of industry-leading electronics technology first used on Mercedes-Benz diesels – electronic fuel injectors that spray gasoline directly into the combustion chambers rather than indirect port fuel injection most gasoline engines used in the past. Featuring a piezo-ceramic crystalline element that changes shape instantly when electrical current is applied, blazingly fast piezo injectors make it possible to design very sensitive and precise injection systems, including the ability to program several small injections with each piston stroke.

The first injection is sprayed into the combustion chamber as the piston is descending on the intake stroke. Depending on speed, load and temperature conditions, another injection or two takes place during the compression up-stroke before ignition, forming a stratified mixture. A fourth injection can stabilize combustion if it's needed.

Multi-Spark Works with Multi-Squirt

Working together with direct injection, a rapid multi-spark ignition system begins combustion with the first spark, but has the capability to recharge and deliver up to three more sparks within a single millisecond, creating a gas plasma with more expansion than conventional ignition.

The time lapse between sparks is adjustable, so combustion duration can actually be controlled, resulting in two percent better fuel economy, and a total of four percent improvement in combination with direct fuel injection.

Refined Cam Chain Drive

Mounted on the ends of the intake and exhaust camshafts, the hydraulic camshaft adjusters that vary valve timing are 35 percent faster than in the past, and with a wider range of 40 crankshaft degrees. Despite their improved performance, they're also more than a half inch smaller in height and width. Smaller valve timing adjusters are made possible by a new cam chain drive system, in which the crankshaft drives an intermediate shaft above the crank. In turn, the intermediate shaft drives two short chains – one for each cylinder bank – that loop around the intake and exhaust camshaft drive sprockets. The latest chain drive results in less tension and lower chain dynamics, for even lower friction and less noise.

A fourth chain drives a variable vane-type oil pump in the bottom of the engine. At low engine speed and load, the oil pump only generates about 28 psi (or two bar) of oil pressure, and nozzles that spray cooling oil on the pistons are off. As engine speed and load increases, oil pressure goes up, and the oil spray nozzles are turned on. In this way, less energy is used when less cooling and lubrication is needed.

Three-Phase, Low-Load Cooling System

Even the cooling system is significantly refined in the direct-injection engine, beginning with a two-stage flow circuit through the cylinder head. This improved coolant flow results in better heat dissipation, despite lower coolant pressure, so that the water pump uses less engine power. A three-phase cooling system helps the engine warm up very quickly. When the engine is first started, no coolant circulates.

Then, as the engine warms up, coolant begins to circulate within the engine, but not through the radiator. Only when the coolant temperature reaches 221 degrees Farenheit (or 189 degrees F. under high load), coolant also circulates through the radiator. Coolant circulation through the heating system for the car's interior is controlled separately.

BlueTEC – A Blueprint For The World's Cleanest Diesels

With 30 percent better fuel economy than a comparable gasoline engine, the ML350 BlueTEC is powered by a purpose-built 3.0-liter V6 diesel producing 240 horsepower and an astonishing 455 lb.-ft. of torque. The ML350 BlueTEC begins with a four-valve-per-cylinder diesel featuring centrally located piezo-electric injectors, CDI direct injection, a variable- nozzle turbocharger and exhaust gas recirculation. Building on this foundation of advanced engine design, the ML350 BlueTEC incorporates several modular after-treatment units in the exhaust stream – an oxidizing catalytic converter, a maintenance-free particulate filter, an SCR converter and an NOx storage converter.

In the "denox" storage converter, nitrogen oxides are absorbed temporarily, and during brief regeneration pulses of a richer fuel-air mixture, the nitrogen oxides are released, reacting with other exhaust gas to form harmless nitrogen. These regeneration pulses also raise temperatures in the particulate filter, which automatically burns off the deposits.

ATTENTION ASSIST Cautions "Time For A Rest?"

Among the many standard life-saving features on the M-Class is the innovative ATTENTION ASSIST system that can alert the driver to the first signs of drowsiness, a factor that causes more than 100,000 accidents a year in the U.S.

A steering sensor is coupled to smart software that uses 70 parameters to establish a unique driver profile during the first 20 minutes of driving. Between 50 and 112 mph, the system identifies the erratic steering corrections drivers make as they begin to get drowsy and triggers an audible warning, and a "Time for a Rest?" message with a coffee cup icon appears in the instrument cluster.

More Safety Systems Assist the Driver

Other examples of trailblazing M-Class innovations include: Lane Keeping Assist, which alerts the driver by simulating rumble strip vibration in the steering wheel if the car drifts from its lane without the turn signals on. It operates at speeds above 37 mph via a system that recognizes lane markings, thanks to a small camera in the windshield and a computer that analyzes the video images.

Blind Spot Assist monitors both blind spots behind and to the side of the vehicle. Whenever a turn signal is activated with a vehicle in the blind spot, the driver gets visual and audible warnings. A separate option, Active Lane Keeping Assist and Active Blind Spot Assist incorporate an intervention feature, in which ESP braking automatically helps correct the car's course if the driver doesn't heed the initial warning.

Adaptive Highbeam Assist uses a small video camera to sense both headlights and taillights, then softly and automatically transitions between high and low beam operation to avoid dazzling other drivers. With this system, the range of the headlights can be varied infinitely from their current 220 feet to up to 1,000 feet.

Electric Rack-And-Pinion Steering

The M-Class comes with an electrically-assisted rack-and-pinion steering unit. Not only does the new electric steering provide built-in speed-dependent power assist, but it also offers fuel savings. The engine no longer has to turn a hydraulic power steering pump, and the new steering only uses electrical power when the wheel is being turned. The electric steering also makes other innovative systems possible, such the optional Active Parking Assist, which makes parallel parking a stress-free cinch.

Below about 20 mph, a "P" icon appears in the dash to show that an electronic parking space search is active. Whenever an adequate-size parking space is found, an arrow appears next to the "P" icon. When reverse is engaged and the driver confirms Advance Parking Assist is desired, the system initiates automatic steering as the driver controls acceleration and braking at speeds below 7 mph. The system allows two forward corrections, after which the wheels are straightened.

PRE-SAFE® Gives M-Class Reflexes to Protect Occupants

PRE-SAFE® is a revolutionary safety system that can actually sense an impending collision before it happens and take measures to protect occupants during those valuable seconds before impact. The PRE-SAFE system tightens the front seat belts before a possible impact. Whenever the PRE-SAFE system is triggered, the side windows also close to provide better support for the window curtain air bags. If the system senses an impending rollover, the sunroof also closes.

The Mercedes-Benz Alabama Plant

Along with the GL-Class, the M-Class sport utility vehicle is produced at the Mercedes-Benz plant in Tuscaloosa, Alabama. The Tuscaloosa plant began production in 1997 with the first generation M-Class. In 2011, the plant produced more than 148,000 vehicles and employed more than 2,800. Starting in 2014, the Tuscaloosa plant also will produce the successor generation of the current C-Class for the North American market. By 2015, Daimler AG will have invested more than $4.4 billion into the facility.

Mighty Mercedes-Benz M-Class triumphs at the Towcar of the Year 2012

Don't Copy From This Blog...

The Mercedes-Benz ML 350 BlueTEC Sport has triumphed in the 2013 Towcar of the Year Awards, winning its category.

The vehicle, which won its class for Vehicle Excise Duty bands J, K, L and M, was subjected to mid-range 30-60 mph acceleration assessment, high-speed towing circuits, emergency braking, ride and handling evaluations and hill-stop and restart tests.

Grenville Chamberlain, Caravan Club Chairman, said: “The Mercedes-Benz ML 350 BlueTEC Sport performed faultlessly. Its strong performance made easy work of the hills, with stop/starts just as easily dismissed. The M-Class has a spacious interior with expected quality feel, comfortable seating and good ergonomics.”

With an updated version of the Mercedes-Benz 3.0-litre V6 CDI engine, the ML 350 BlueTEC Sport, which was launched April 2012, develops 258 hp at 3,600 rpm and 620 Nm of torque between 1,600 and 2,400 rpm. With combined economy of 39.2 mpg, the ML 350 BlueTEC shows a 20.6 per cent improvement over the previous model, while the CO₂figures of 189 to 194 g/km represent a reduction of up to 17.8 per cent. The performance increase means the ML 350 can accelerate from 0-62 mph in 7.4 seconds and reach a top speed of 139 mph.

Gary Savage, Managing Director of Mercedes-Benz Passenger Cars UK, said: “We are incredibly proud of the M-Class, with its reduction in CO2 and improvements in performance and economy; the vehicle really is class-leading. The category win in the 2013 Towcar of the Year Awards further demonstrates its outstanding capabilities.”

Priced at £48,475 on the road, the ML 350 BlueTEC Sport features 4MATIC intelligent electronic all-wheel drive via the Mercedes-Benz seven-speed 7G-TRONIC PLUS automatic transmission, as well as self-levelling, automatic headlamp adjustment, ESP® Trailer Stability Assist and limited slip differential as standard.

The new Mercedes-Benz ML 500 BlueEFFICIENCY: More performance, more equipment in the new model year

Don't Copy From This Blog...

The third generation of the M-Class was launched in September 2011 and, in common with its predecessors, it has had an enduring impact on the SUV sector. An additional V8 petrol version now joins the range in the shape of the ML 500 4MATIC BlueEFFICIENCY. The equipment package is also further enhanced by new safety features such as COLLISION PREVENTION ASSIST (CPA)*. The new ML 500 4MATIC BlueEFFICIENCY can be ordered from 22 June and will be arriving at dealerships in autumn 2012.

The new ML 500 4MATIC BlueEFFICIENCY, which features a turbocharged BlueDIRECT V8 direct injection petrol engine, offers outstanding performance along with top-class efficiency. The new model outperforms fuel consumption figures of its predecessor by 16 percent – while simultaneously boosting performance. The V8 engine develops increased output from a significantly smaller displacement (4663 rather than 5461 cc): the ML 500 4MATIC BlueEFFICIENCY now generates 300 kW (408 hp) instead of 285 kW (388 hp). Torque has been increased from 530 to 600 Nm and is available at a much lower engine speed of 1600 rpm.

The high output despite reduced displacement is achieved mainly by the use of two exhaust gas turbochargers – one for each bank of cylinders. Other innovations of the new V8 engine include a further developed, third-generation direct fuel injection system with spray-guided combustion and piezo injectors combined with multi-spark ignition. The outstanding fuel economy is underpinned not only by the V8 model's state-of-the-art engine technology, but also by a comprehensive package of BlueEFFICIENCY measures. In addition to the ECO start/stop function which comes as standard, these measures include the seven-speed 7G-TRONIC PLUS automatic transmission.

Low-friction axle drives, electric steering, optimised belt drive and on-demand control of the ancillary components also play their part in reducing fuel consumption. Below is a summary of key data for all M-Class models:

New equipment features make the M-Class even more attractive

All models from model year 2013 impress with new equipment details. Active safety is further enhanced with the inclusion of COLLISION PREVENTION ASSIST (CPA)* with adaptive Brake Assist as standard. Guaranteeing a secure footing are the elegant 5-twin-spoke 48.3 cm (19") alloy wheels, included in the ML 500 4MATIC BlueEFFICIENCY delivery package, or the all-new 5-spoke 53.3 cm (21") alloy wheels from Mercedes-Benz Accessories. The colour chart offers two gleaming new paint finishes: cavansite blue and cinnabar red. For those seeking an even more enjoyable driving experience in urban traffic, the M-Class is optionally available with Active Parking Assist. This electronic co-pilot automatically seeks out a suitable parking space and takes over steering duties during the parking process. A further option to optimise operational comfort is the electric servo-locking mechanism, which automatically closes all doors and the boot lid.

The optional multicontour seats for driver and front passenger offer maximum comfort with new massage functions, fine-tuning via the COMAND system and luxury head restraints and seat cushion depth adjustment. When the interior becomes excessively warm – for example after a long period parked in hot sunshine – reverse flow seat cooling shortens the cooling period by first drawing air out of the seat before pumping it back in.

As of the new model year, the cockpit TFT display between the two instrument dials boasts an almost photorealistic image; in keeping with the COMAND screen it adopts the modernised display concept of a silver-grey colour scheme. With the internet-capable COMAND Online infotainment system on board, the delivery package additionally features the Mercedes-Benz automatic emergency call system. In the event of a serious accident, the system notifies emergency services automatically and within minutes transmits detailed information about the exact location of the accident and the vehicle model involved.

Mercedes-Benz optionally offers the M-Class with a sound system by renowned audio specialists Bang & Olufsen. The Bang & Olufsen BeoSound AMG high-end surround sound system, with a combined 1200 watt output and 14 high-end speakers, transforms the vehicle interior into a concert hall with breathtaking acoustics.

Various equipment packages are available for those seeking an even more exclusive look for their M-Class. For an enhanced dynamic appearance, for example, there is the AMG Exterior Sports package, featuring special body-coloured front apron, rear apron and side skirts, in addition to 48.3 cm(19") 5-spoke high-sheen AMG alloy wheels. The luxurious designo Exclusive package in black, maroon or porcelain adds new class to the interior. This feature includes seats, instrument display, door centre panels, door arm rests, beltlines and centre console upholstered in nappa leather, in addition to the designo roof lining in black DINAMICA microfibre.

Increased possibilities with optional vehicle dynamics systems

The ON&OFFROAD package for the 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. With the lighting package featuring the Intelligent Light System onboard, the M-Class driver will also benefit from a lighting system specifically optimised for off-road use.

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) (standard in the ML 500 4MATIC BlueEFFICIENCY) 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 even greater ride comfort both when cornering and driving in a straight line, together with enhanced off-road abilities.

Outstanding million-seller from €55,394.50

With sales of over 1.2 million vehicles, the M-Class is the most successful Mercedes-Benz SUV. At its world premiere in 1997, the M-Class was considered the precursor of all modern premium SUVs. The third generation was presented in 2011; like its predecessors, it achieved outstanding results in a wide range of polls and rankings. In its debut year the M-Class was awarded the golden steering wheel. TÜV Süd recognised the vehicle’s high environmental compatibility and awarded the M-Class its coveted environmental certificate. The SUV passed crash tests in line with European NCAP procedures, achieving the maximum five-star rating for outstanding passenger protection.

Latest successes from 2012: With NEDC fuel consumption figures of just 6.0 l/100 km, the efficiency champion ML 250 BlueTEC 4MATIC was voted most eco-friendly car in its class by the “ÖkoTrend” institute. Moreover, the trade journal AUTO TEST named the premium SUV its “Winner in Green”. In March, the readers of Europe’s leading 4x4 magazine Auto Bild Allrad voted the Mercedes-Benz M-Class “Car of the Year 2012”.

New Mercedes-Benz ML 250 BlueTEC 4MATIC: Range of up to 1500 kilometres

Don't Copy From This Blog...

The third generation of the Mercedes-Benz M-Class sets new standards in the SUV sector, and particularly impresses with its low fuel consumption and emission figures. Compared to the previous series, the entire model range of the new M-Class consumes an average of 25 percent less fuel. Outstandingly, the ML 250 BlueTEC 4MATIC is content with an NEDC consumption of 6.0 l/100 km (158 g CO2/km) and can travel up to 1500 kilometres on a single tankful. Efficiency notwithstanding, the fascination of the M-Class with its unique synthesis of agility, driving pleasure and comfort is fully preserved.

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 power unit already familiar from the S-Class. The NEDC consumption of 6.0 l/100 km is 28 percent lower than that of the previous model. Thanks to AdBlue® exhaust aftertreatment, the diesel meets the EU-6 standard due to come into force from 2014.

The calculatory range with 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 between fuel-stops. If the vehicle is fitted with the optional 93-litre‑tank, the car can even cover up to 1500 kilometres between fuel-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, low-friction bearings and a transmission oil thermal management system. Low-friction axle drives, electric steering, the optimised belt drive, 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 of Cd = 0.32, the new M-Class (ML 250 BlueTEC) also sets a new best figure for this vehicle class. 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, the A-pillars and the roof spoiler, plus numerous other detailed improvements.
