Mercedes-Benz E63 AMG

Mercedes-Benz E63 AMG

Shortly after the launch of the new E-Class, AMG is kicking off the new 2009 motoring season with the introduction of the new Mercedes-Benz E63 AMG. This dynamic sports saloon with day-to-day suitability impresses with outstanding performance, thrilling handling characteristics and a technology transfer from the SL63 AMG high-performance Roadster.

The new Mercedes-Benz E63 AMG distinguishes itself from the regular Mercedes-Benz E-Class models with a completely newly developed AMG RIDE CONTROL sports suspension with electronically controlled damping and a new front axle, and with its autonomous exterior and interior design. At the same time Mercedes-AMG has achieved a reduction in fuel consumption by almost 12 percent for the new Mercedes-Benz E63 AMG, thanks to the concerted use of fuel efficiency measures. With its unique combination of pioneering driver assistance systems, the Mercedes-Benz E63 AMG further consolidates the brand's leading position in the field of automotive safety.

The AMG 6.3-litre V8 engine in the new Mercedes-Benz E63 AMG develops a power output of 525 hp and a torque figure of 630 Nm, matching the outstanding figures for the SL63 AMG. The high-performance Roadster has also donated its AMG SPEEDSHIFT MCT 7-speed sports transmission to the new model. It dispenses with a conventional torque converter and uses a compact, wet start-up clutch. In conjunction with the four individual driving modes, the throttle-blipping and RACE START functions, the resulting, direct connection to the powertrain allows an extremely emotional and highly dynamic driving experience.


The drive unit is unique in this segment, and ensures sporty performance figures: the Mercedes-Benz E63 AMG accelerates from 0-62 mph in just 4.5 seconds, with a top speed of 155 mph (electronically limited). The fast-revving, naturally aspirated engine with a displacement of 6208 cc impresses with its agile responsiveness, muscular power delivery and great flexibility. The newly composed AMG V8 sound is a thrilling accompaniment mile after mile, while the smooth-running engine guarantees typical Mercedes-Benz long-distance comfort. A newly designed water cooling system ensures maximum endurance even under the enormous dynamic stresses of the racetrack.

Fuel consumption cut by almost 12 percent

Despite 11 hp of additional output versus the preceding model, the fuel consumption of the new Mercedes-Benz E63 AMG has been significantly improved. It now returns 22.4 mpg, 2.6 mpg more than then previous car (NEDC combined consumption, provisional figure), and leads the field among sports saloons developing more than 500 hp. This progress has been made possible by a package of efficiency-enhancing measures. These include on-demand delivery of fuel and generator management with recuperation of braking energy on the overrun, both of which are standard in the new Mercedes-Benz E63 AMG. In-engine friction is also reduced by the AMG-exclusive twin-wire arc spray coating process used on the cylinder walls.

The AMG SPEEDSHIFT MCT 7-speed sports transmission also makes a decisive contribution to fuel economy: a wet start-up clutch running in an oil bath replaces the previous torque converter. This unit responds extremely rapidly, dynamically and without the losses typical of a torque converter transmission thanks to its low rotational inertia. The transmission is equipped with four driving modes: "C" (Controlled Efficiency), "S" (Sport), "S+" (Sport plus) and "M" (Manual), which can be selected using a rotary electronic switch in the AMG DRIVE UNIT. Partial suppression of individual cylinders by interrupting ignition and injection during gearshifts under full load leads to considerably faster shift times. In M mode the AMG SPEEDSHIFT MCT 7-speed sports transmission allows gearshifts to be performed in 100 milliseconds.

In the even more fuel-efficient driving mode Controlled Efficiency, the transmission shifts the gears decidedly smoothly, and the transmission control unit is programmed to perform early upshifts to keep engine speeds as low as possible. At the same time the AMG SPEEDSHIFT MCT 7-speed sports transmission meets the most demanding requirements where driving dynamics are concerned: fast and precise multiple downshifts ensure first-class agility in conjunction with the automatic throttle-blipping and RACE START function: this enables the Mercedes-Benz E63 AMG driver to call on the maximum acceleration potential automatically.

Electronically controlled damping system and a new front axle

Sporty or more comfort-oriented? The driver of the new Mercedes-Benz E63 AMG is not obliged to accept any compromises in this respect. The AMG RIDE CONTROL sports suspension copes equally well with the agile manoeuvres of the racetrack and more comfortable, sedate driving. High performance and typical Mercedes-Benz long-distance comfort go together as an extraordinary synthesis in the Mercedes-Benz E63 AMG. This is made possible by the newly developed AMG RIDE CONTROL sports suspension. While new steel spring struts are used on the front axle, the rear suspension features AMG-specific air springs. The advantage of this solution, which is exclusive to AMG, is that the front spring struts ensure more sensitive responses while the rear air struts with their automatic level control system keep the vehicle at a constant height irrespective of the load.

A new, electronically controlled damping system automatically varies the damping characteristics according to the driving situation, reducing the roll angle of the body. The result is instant adjustment to provide the best possible ride comfort together with the greatest possible agility. In addition the driver is able to choose between the three suspension modes of Comfort, Sport and Sport plus at the touch of a button. The Mercedes-Benz E63 AMG is also equipped with a newly developed, dedicated front axle with a 56 mm wider track, a tubular stabiliser, new control arms, new wheel bearings, new elastokinematics and new wheel location for more negative camber - thereby providing more grip when taking bends at speed. The AMG-specific kinematics also ensure significantly more precision. This is a highly sophisticated axle design whose principle has already proved its worth in the C 63 AMG. The rear axle likewise has more negative camber, optimised elastokinematics and a new subframe mounting for greater stability at the physical limits.

Newly developed power steering and individual 3-stage ESP®

For more direct responsiveness, the speed-sensitive rack-and-pinion steering is also a new development. The steering ratio of 14 : 1 is 22 percent more direct than in the standard production models, while a more rigid steering column plus the reconfigured characteristic mapping of the speed-sensitive servo assistance ensure better steering precision and improved road contact.

The 3-stage ESP® familiar from the SL63 AMG and C63 AMG enables individual settings to be selected - with clear benefits in terms of driving pleasure combined with the same, high level of handling safety. The ESP® key in the AMG DRIVE UNIT allows the driver to choose between "ESP ON", "ESP SPORT" and "ESP OFF" - with the currently active mode shown in the central display of the AMG instrument cluster. Perfect deceleration even when driving extremely briskly is ensured by the AMG high-performance braking system with 360 mm, internally ventilated and perforated brake discs all-round. Particularly resistant, motorsports-tested composite technology is used at the front axle. Outstanding grip is ensured by the 18-inch AMG light-alloy wheels with a width of nine and 9.5 inches and mixed tyre sizes of 255/40 R 18 at the front and 285/35 R 18 at the rear.

Decidedly dynamic interior and exterior

The decidedly dynamic design of the Mercedes-Benz E63 AMG is fully in keeping with the uncompromisingly sporty technology. The front aspect is characterised by 17 mm wider wings bearing "6.3 AMG" lettering, the new AMG front apron with large air intake apertures and the AMG-specific daytime driving lights using LED technology. In conjunction with the standard Intelligent Light System, the Mercedes-Benz E63 AMG is equipped with tinted main headlamps. The striking visual presence is further enhanced by the AMG side skirts and AMG rear apron with a black diffuser insert. As a hallmark of the brand, the AMG sports exhaust system has two newly designed, chrome-plated twin tailpipes.

The newly designed interior of the Mercedes-Benz E63 AMG is an exciting blend of high-grade materials and functional sportiness. Exclusive features include the dedicated, electrically adjustable AMG sports seats with improved lateral support and the AMG sports steering wheel in a four-spoke design with AMG shift paddles. As a completely new feature exclusive to the Mercedes-Benz E63 AMG, the AMG selector lever has one-touch logic. Directly adjacent to it in the centre console is the AMG DRIVE UNIT, which provides adjustments for the MCT sports transmission, the ESP functions, the suspension set-up and the AMG driving modes. Standard equipment also includes high-grade nappa leather upholstery in three different colours, the AMG instrument cluster with an AMG main menu, door entry sills with AMG lettering and a sports pedal cluster - both in brushed stainless steel.

Even more individuality with tailor-made AMG extras

Customers requiring even more sporty individuality are catered for by the AMG PERFORMANCE STUDIO: the Mercedes-Benz E63 AMG can be dynamically enhanced with the Performance Package. This includes the following:

On request the safety features can be brought to a level unprecedented in this vehicle class with the Lane Keeping Assist and Blind Spot Assist systems, the PRE-SAFE® Brake with an automatic braking function which can bring the vehicle to a complete stop, Adaptive Highbeam Assist and Night View Assist.

Mercedes-Benz E63 AMG Estate

Mercedes-Benz E63 AMG Estate

Pole position for the new Mercedes-Benz E63 AMG Estate: the high-performance estate develops 386 kW/525 hp, accelerates from 0 to 100 km/h in 4.6 seconds, offers a maximum luggage compartment capacity of 1950 litres - all with a relatively low fuel consumption of 12.8 litres per 100 km (combined, provisional figures). With these dream figures, the new Mercedes-Benz E63 AMG Estate adds up to an extraordinary combination of driving dynamics, high utility value and superb efficiency.

The top-of-the-line Mercedes-Benz E-Class not only features its distinctive styling but also the all-new AMG RIDE CONTROL sports suspension including electronically controlled damping system and a new front axle. A composite ceramic braking system is available for the first time for the Mercedes-Benz E63 AMG Estate. The unrivalled combination of groundbreaking driver assistance systems raises the bar in terms of active and passive safety in this vehicle class.

Largest luggage compartment and lowest fuel consumption - the Mercedes-Benz E63 AMG Estate sets new standards. With a luggage compartment capacity of 695 to 1950 litres and fuel consumption of 12.8 litres Super Plus per 100 kilometres (NEDC combined), the new high-performance estate from AMGstands on pole position. None of its rivals can match this extraordinary combination of performance, utility value and efficiency. The AMG 6.3-litre V8 engine with its 386 kW/525 hp develops 8 kW/11 hp more than the previous model, yet betters its fuel consumption figures by almost twelve percent.


This improvement was achieved thanks to a whole raft of efficiency-enhancing measures. The on-demand delivery of fuel and generator management with recuperation of braking energy on the overrun has helped reduce fuel consumption, just like the AMG SPEEDSHIFT MCT 7-speed sports transmission: a wet start-up clutch that runs in an oil bath replaces the conventional torque converter, while the even more fuel-efficient driving mode "Controlled Efficiency" utilises early upshifts to keep engine speeds as low as possible.

The new Mercedes-Benz E63 AMG Estate delivers a compelling proposition with its two fundamentally opposed traits: it masters the sedate driving of an executive estate suitable for long journeys just as consummately as the enormously dynamic manoeuvres on the racetrack. The AMG high-revving, naturally aspirated engine with a displacement of 6208 cc and 630 Nm of torque impresses with its agile responsiveness, muscular power delivery and great flexibility. The Mercedes-Benz E63 AMG Estate reaches 100 km/h in just 4.6 seconds, with a top speed of 250 km/h (electronically limited). The newly composed V8 sound is a thrilling accompaniment for mile after mile, while the smooth-running engine guarantees typical Mercedes ride comfort. A newly designed water cooling system ensures maximum endurance even under enormous stresses.

The AMG SPEEDSHIFT MCT 7-speed sports transmission meets the driver's most disparate requirements: the transmission is equipped with four drive modes: "C" (Controlled Efficiency), "S" (Sport), "S+" (Sport plus) and "M" (Manual), which can be selected using a rotary electronic switch in the AMG DRIVE UNIT. In the even more fuel-efficient drive mode Controlled Efficiency, the transmission shifts the gears decidedly smoothly, and the transmission control unit is programmed to perform early upshifts to keep engine speeds as low as possible.

In Sport plus and Manual modes, the 7-speed sports transmission allows gearshifts to be performed in 100 milliseconds. Partial suppression of individual cylinders by interrupting ignition and injection briefly during gearshifts under full load leads to considerably faster shift times. Fast, spontaneous multiple downshifts ensure first-class agility in conjunction with the double-declutching and RACE START function: this enables the Mercedes-Benz E63 AMG driver to call on the maximum acceleration potential automatically.

Driving dynamics and ride comfort - the Mercedes-Benz E63 AMG Estate delivers on both counts

Like the engine and power transfer, the newly developed AMG RIDE CONTROL sports suspension offers the ultimate in individuality. Outstanding driving dynamics and typical Mercedes long-distance comfort go together as an optimum synthesis in the Mercedes-Benz E63 AMG Estate. While new steel spring struts are used on the front axle, the rear suspension features AMG-specific air springs. The advantage of this solution is that the front steel springs ensure more sensitive responses while the rear air struts with their automatic level control system keep the vehicle at a constant height irrespective of the load.

A new, electronically controlled damping system automatically varies the damping characteristics according to the driving situation, reducing the roll angle of the body. The result is instant modification to provide the best possible ride comfort together with the greatest possible agility. In addition the driver is able to choose between the three suspension modes of Comfort, Sport and Sport plus at the touch of a button. The Mercedes-Benz E63 AMG Estate is also equipped with a newly developed, dedicated front axle with a 56-millimetre wider track, a tubular stabiliser, new control arms, new elastokinematics and new hub carriers for more negative camber - thereby providing more grip when taking bends at speed. This is a highly sophisticated axle design whose principle has already proved its worth in the Mercedes-Benz C63 AMG Estate. The rear axle likewise has more negative camber, optimised elastokine-matics and a new subframe mounting for greater stability at the physical limits.

Newly developed power steering and individual 3-stage ESP®

A more direct steering feel comes courtesy of the all-new speed-sensitive rack-and-pinion steering. The steering ratio of 14 : 1 is 22 percent more direct than in the standard production models, while a more rigid steering column plus the reconfigured characteristic mapping of the speed-sensitive servo assistance ensure better steering precision and improved road contact.

The 3-stage ESP® familiar from the Mercedes-Benz SL63 AMG and C63 AMG enables individual settings to be selected - with clear benefits in terms of driving pleasure. The ESP® button in the AMG DRIVE UNIT allows the driver to choose between "ESP ON", "ESP SPORT" and "ESP OFF" - with the currently active mode shown in the central display of the instrument cluster. Perfect deceleration even when driving extremely briskly is ensured by the AMGhigh-performance braking system with 360-millimetre, internally ventilated and perforated brake discs all-round. Particularly resistant, motorsports-tested composite technology is used at the front axle. The newly developed, optional ceramic composite brakes with larger brake discs guarantee even better brake performance and a longer service life. The ceramic brake discs will perform reliably at even higher operating temperatures thanks to their greater hardness, all combined with an impressive weight reduction of around 40 percent. The reduced unsprung masses translate into even more agile handling, particularly on fast motorway bends.

Optimum grip is ensured by the 18-inch, titanium grey, high-sheen AMG five-spoke light-alloy wheels with a width of nine and 9.5 inches and mixed tyre sizes of 255/40 R 18 at the front and 285/35 R 18 at the rear. Lightweight, forged 19‑inch AMG light-alloy wheels with size 255/35 R 19 tyres at the front and 285/30 R 19 at the rear are also available as an option.

AMG bodystyling and wider front wings

The newly developed front axle with its wider track calls for wings that are 17 mm wider. The stylish integrated "6.3 AMG" lettering leaves the connoisseur in no doubt about the unique credentials of the high-performance estate. The AMG bodystyling also includes a front apron with large cooling air intakes, air outlets at the side and the AMG-specific LED daytime driving lights. In conjunction with the optional Intelligent Light System (ILS), the Mercedes-Benz E63 AMG Estate is equipped with tinted main headlamps. The side skirts and the rear apron with its black insert also guarantee the car's striking looks. Both styling features combine effortlessly with the graceful line that follows the rear wheel arches and lends a clear shape to the imposing, muscular contours of the rear wings. The standard specification includes ultra-fast LED tail lights and direction indicators. To create a lasting impression - on the eye and the ear - the sports exhaust system has two newly designed, chrome-plated twin tailpipes.

Luggage compartment with the largest capacity and great practicality

Thanks to the wheelbase that has been enlarged by 20 millimetres, the Mercedes-Benz E63 AMG Estate not only offers better ride comfort but also more space and luggage compartment capacity than the previous model. With its capacity of 695 to 1950 litres, the luggage compartment is not only larger than before but also leaves the competition standing when it comes to the essential luggage compartment dimensions and capacity. This highly practical concept paves the way for numerous options for transporting sports equipment, holiday luggage or high-quality designer furniture.

Standard equipment for the Mercedes-Benz E63 AMG Estate includes the main components of the EASY-PACK system such as the folding load compartment floor with two loading levels and collapsible crate, the load compartment cover, quickfold to fold down the 1/3:2/3-split rear backrest easily and the EASY-PACK tailgate, which can be opened and closed electrically.

Interior with sporty feel-good atmosphere

The newly designed interior of the high-performance estate is an exciting blend of high-grade materials and functional sportiness. Exclusive features include the dedicated, electrically adjustable sports seats with improved lateral support and the sports steering wheel in a four-spoke design with aluminium shift paddles. The AMG DRIVE UNIT provides adjustments for the MCT sports transmission, the 3-stage ESP®, the suspension set-up and the AMG drive modes. The E-SELECT selector lever in the centre console is a completely new feature for the DRIVE UNIT. The driver can shift directly between R, N and D simply by nudging the lever, all thanks to drive-by-wire; the parking lock P can be selected conveniently by pressing a button. Standard equipment also includes high-grade leather upholstery in three different colours, the AMG instrument cluster with an AMG main menu as well as the door entry sills with AMG lettering and a sports pedal cluster - both in brushed stainless steel.

Mercedes-Benz GLK 350 4MATIC

Mercedes-Benz GLK 350 4MATIC

Mercedes-Benz released official pictures and information of the all-new Mercedes GLK-Class sport utility vehicle. The versatile SUV will debut at Auto China in Beijing on Sunday, April 20, and make its U.S. dealer showroom debut in January 2009 as a 2010 model.

Powered by a 268-horsepower, 3.5-liter V6 engine the 2010MY GLK 350 will form the basis of the U.S. lineup, and will be offered in both 4MATIC and two-wheel-drive versions, riding on standard 19-inch 10-spoke wheels with 235/50 tires. The GLK features a 108.5-inch wheelbase and boasts unique design language which sets it apart from the rest of the highly successful Mercedes-Benz family of SUVs that includes the M-Class (which spurred the trend toward more car-like SUVs), the larger GL-Class, the crossover R-Class and the iconic G-Class.

Showcasing bold exterior design, generous cargo capacity and available 4MATIC all-wheel-drive, the GLK 350 combines the perfect balance of styling, versatility and performance. The 2010 Mercedes-Benz GLK-Class will be produced exclusively at the Mercedes-Benz plant in Bremen, Germany.

Aggressive Styling and a Unique Personality

With its poised, confident presence, the GLK-Class leaves no doubt about its intent to conquer the compact premium SUV segment. In sharp contrast to the relatively soft forms of other similar-sized vehicles, the striking, angular profile of the GLK sets it apart from the competition. From its steeply-raked windshield to the integrated rear spoiler on its tightly styled roof section, the bullish shape of the new Mercedes GLK suggests power and agility, and echoes the G-Class -- the iconic pioneer of the Mercedes-Benz SUV family.


Mercedes-Benz Design Chief Prof. Peter Pfeiffer adds: "With the G-Class we created a style icon that has been a benchmark in SUV design for the past 30 years. Combining this bold concept with the latest Mercedes-Benz design idiom makes the GLK a vehicle of genuine character."

Beautiful proportions (length 178.3 inches, width 72.4 inches, height 66.9 inches) and styling combine classic angular shapes together with the distinctive design features found in contemporary Mercedes-Benz passenger cars. Taut lines and large, expansive surfaces mix with the traditional characteristics of a proper off-road vehicle, such as short overhangs, an upright front end, slim roof pillars, and a steeply raked windshield. Generous angles of approach and departure combined with impressive ground clearance allow the GLK to handle light off-roading with ease. On-road, the clear layout of the exterior and good all-around visibility, combined with a commanding seating position, enhance everyday practicality and relaxed driving, even in dense city traffic.

A Luxurious, Feature-Rich Interior

The GLK boasts a long list of standard equipment, including details not typically found in this vehicle class. Inside, a two-zone automatic climate control system, adjustable steering column, front seats with electrically adjustable height and backrest angle (including seat inclination adjustment) and manual lumbar support with two-way adjustment for the driver's seat are all standard on the GLK. Standard integrated Bluetooth interface for mobile phones, a microphone for the hands-free system and a central 5-inch color display round out the list of interior appointments.

The 2010 Mercedes-Benz GLK features all the impressive design and safety technology found in other Mercedes-Benz models, including standard front and side air bags as well as window air bags. Among its many comfort and convenience features is an available rear-seat entertainment system featuring two eight-inch screens, wireless headphones and an integrated dual-source DVD player.

The distinctive looks of the GLK exterior are seamlessly continued inside, with luxurious materials and precise detailing. The taught, sculpted lines of the dashboard dominate the interior, visually extending into the door panels to lend additional width to the generously dimensioned cockpit. Luxurious Sienna Pine wood with chrome trim highlights the dashboard and door panels at the front and rear, while the upper section of the encompasses the instrument cluster and the standard 5-inch color display. The driver's armrest features integrated cupholders and the standard controller for the audio functions and the optional COMAND multimedia system are located in ergonomically ideal positions between the front seats. Control of the individual menus is intuitive, following the familiar and well-proven layout used in the current C-Class and S-Class models. Additional shortcut buttons provide direct access to the most important main functions. Front and rear headroom figures are 39.8 inches and 39.7 inches respectively, while the cargo area boasts 23.3 cubic feet of storage. Cargo capacity balloons to 54.7 cubic feet when the 1/3:2/3-split rear seats are folded forwards.

A Wealth of Optional Equipment for the GLK buyer

Contributing to the versatility of the new SUV, five option packages as well as nine stand-alone options are planned for the 2010 Mercedes-Benz GLK 350. The popular Premium 1 package offers GLK buyers a spacious Panorama Sunroof, SIRIUS satellite radio and a power liftgate. Customers seeking even more luxury can opt for the Premium 2 package, which adds Bi-Xenon headlamps with adaptive lighting and headlamp washing system, rain sensing windshield wipers, memory settings for the driver's seat, and much more. The Multimedia Package (which debuted on the new C-Class) adds COMAND with hard-drive Navigation as well as a rear-view back-up camera. Exterior options include an Appearance Package offering larger 20-inch 7-spoke wheels and Aluminum roof rails and, for the interior, an Upholstery Package adds interior lighting, a full leather interior and burl walnut trim.

Available 4MATIC All-Wheel-Drive System

The optional all-wheel-drive powertrain at the heart of the GLK 350 4MATIC is one of the most capable systems on the market. The dynamic ESP®, ASR and 4ETS driving systems work in concert to ensure top-notch longitudinal and lateral control and superb handling stability both on and off-road. Thanks to a compact, longitudinally designed engine, transmission and transfer case arrangement, the system offers various advantages over its counterparts equipped with a transversely installed drive unit. Estimated 23 mpg highway fuel consumption is on a par with comparable rear-wheel vehicles, while vibration and noise levels rival those of luxury models.

The 45:55 torque distribution between the front and rear axle - along with the ESP®, ASR and 4ETS dynamic handling control systems - guarantees effortless and exceptional performance. Loss of traction on snow or ice is compensated for by the newly developed multi-disc clutch in the center differential, which provides a basic partial locking torque between the front and rear axle. This arrangement produces a significant increase in traction while maintaining directional stability.

Agility Control Suspension

The sophisticated Agility Control suspension on the new Mercedes GLK-Class helps resolve a common paradox facing the SUV segment - how to create a vehicle that combines agile on-road comfort with off-road capability. For sporty, responsive handling, the suspension and, above all, the shock absorbers need to provide a certain firmness however, this may compromise comfort and limits off-road performance. If the vehicle is setup with softer dampers, dynamic handling naturally suffers. Thanks to "amplitude-dependent damping" the suspension can adjust to perform in either driving conditions. During normal driving on moderately contoured roads or slow off-road manoeuvres, the system responds softly, enhancing both the occupants' comfort and the vehicle's off-road capability. During more spirited driving or when performing abrupt evasive maneuvers, the dampers adjust to a harder setting ensuring optimum handling stability. Additionally, speed-sensitive power steering supports the driver with a precise balance of high-speed road feel and low speed maneuverability. Maximum power assistance is available during parking and off-road driving, while at higher speeds, the assistance is reduced in favor of greater handling stability.

In addition to a tire pressure warning system, the tried-and-tested Electronic Stability Program (ESP®) for the GLK incorporates a vehicle/trailer stabilization function, which helps maintain control while towing a trailer by applying the individual wheel brakes as required. The GLK offers a maximum tow rating of 3,500 lbs.

Complete Safety Package for Maximum Occupant Protection

In combination with the front and rear deformation zones, the GLK's high-strength passenger cell provides a highly efficient foundation for the occupant protection systems, which include:
Adaptive, two-stage airbags for the driver and front passenger
Front side-impact airbags
Windowbags across both seat rows from the A-pillar to the C-pillar
Active head restraints for the driver and front passenger
Crash-optimized pedal system
3-point seat belts for all five seats
Belt tensioner and adaptive belt-force limiter for the driver and front passenger, belt tensioner and single-stage belt-force limiter for the outer rear seats
ISOFIX child seat attachments
Belt height adjuster for the driver and front passenger
Belt status indicator for the rear passengers in the instrument cluster

Mercedes remains true to the philosophy that the best accidents are the ones that are avoided entirely. With this in mind, standard equipment for all GLK models includes Brake Assist (BAS), which shortens the braking distance significantly -- especially during panic braking -- to help prevent accidents or at the very least mitigate their consequences. The front section incorporates precisely defined crumple space between the body and the major assemblies beneath, allowing the hood to yield considerably if hit by a pedestrian, cyclist or motorcyclist. Together with the specially designed front bumpers and the softer foam of the integrated bumper impact absorbers, these measures afford pedestrians a high degree of protection.

Proven V6 Powerplant

The new sport utility is destined to be one of the most fuel-efficient Mercedes-Benz vehicles ever. Smaller and lighter than its well-known SUV siblings, the GLK features a fuel-sipping 3.5-liter V6 engine, a sophisticated seven-speed automatic transmission and available 4MATIC full-time four-wheel-drive. All of these components combine to give the GLK 350 an impressive 0-60 time of just 6.5 seconds (estimated) while achieving an 23 mpg (estimated) on the highway.

Both the GLK 350 and GLK 350 4MATIC are matched with a seven-speed automatic transmission as standard. Low overall weight (estimated 4,036 lb. curb weight) and the exceptional aerodynamics for a vehicle of this design (cd figure 0.35) further contribute to the exceptional performance and low fuel consumption.

Much as the latest C-Class sedan has brought a new level of sporty driving and ride comfort to the sedan world, the new Mercedes GLK brings a new combination of agility and comfort to the SUV market. The GLK also broadens and extends the Mercedes-Benz sport utility line with cutting-edge engine and four-wheel-drive technology packaged in a stylish vehicle that's the perfect size for today's busy family.

The Widest Range of SUVs

Mercedes-Benz offers the widest range of SUVs in the premium segment, the GLK being the brand's fifth model in the series. In response to customers' wishes, the company's Family of SUV's has grown to include the R-Class, M-Class, GL-Class and G‑Class. The new Mercedes GLK is the latest addition to this successful line-up.

Brimming with genuine character, the new Mercedes-Benz GLK-Class is set to take the world of compact SUVs by storm. Yet it is not just the distinctive all-rounder's practical and appealingly compact body form that sets it apart from the competition. It also brings together what were previously seen as entirely contradictory attributes. The Agility Control suspension serves up a unique blend of outstanding handling dynamics, exceptional driving safety and superlative ride comfort. Meanwhile the sophisticated, variable 4MATIC all-wheel-drive system joins forces with the latest electronic control systems to deliver consummate on-road performance and superb off-road suitability. It is precisely this kind of combination that lends the Mercedes-Benz GLK-Class such immense appeal. The GLK-Class may be one of the more road-oriented Mercedes-Benz SUVs, but the "G" - alluding to the archetypal Mercedes off-roader - still has a rightful place in the model name.

Superlative performance comes courtesy of the powerful yet economical and eco-friendly four and six-cylinder engines. The BlueEFFICIENCY version of the GLK 220 CDI features the new entry-level four-cylinder diesel engine from Mercedes-Benz, which develops 125 kW/170 hp yet only consumes 6.9 litres of diesel per hundred kilometres. And the unshakeable foundations of the Mercedes-Benz GLK-Class are similarly impressive. The highly robust body is key to the pioneering passive-safety setup, the extremely low noise levels, the exceptional degree of interior comfort - to produce that typical Mercedes feeling of wellbeing - and the high value retention. Furthermore, exemplary appointments and attractive equipment packages make the GLK stand out from the compact-SUV masses. Plus state-of-the-art systems such as the leading-edge PRE-SAFE safety concept and the Intelligent Light System (ILS) are available in this market segment for the very first time.


With its poised, confident presence, the mere look of the Mercedes-Benz GLK-Class leaves one in no doubt about its intent to conquer the compact premium SUV segment. It is arguably the most sophisticated of all takes on this particular theme. And it displays echoes of the G-Class, the founding father of the Mercedes-Benz SUV family. Design chief Prof. Peter Pfeiffer takes up the story: "With the G-Class we created a style icon that has been a benchmark in SUV design for the past 30 years. Combining this bold concept with the latest Mercedes-Benz design idiom makes the GLK a vehicle of genuine character."

No other model in the compact-SUV segment, past or present, comes close to matching the GLK's distinctively expressive appearance. The body is beautifully proportioned (length 4528 mm, width 1840 mm, height 1689 mm), while there is a special allure in the interplay between the classic angular shape and the typical design features found in all contemporary Mercedes-Benz passenger cars. Here the unmistakable design idiom, consisting of taut lines and large, expansive surfaces, is combined with the typical body features of a practical off-road vehicle, such as short overhangs, an upright front end, slim roof pillars, a steeply raked windscreen and taut roof lines. Rather than being a stylistic end in itself, however, the body design allows the typical advantages of an off-road vehicle to be introduced to the more road-oriented compact-SUV category for the first time. Large angles of approach and departure plus good ground clearance make off-road ventures a sheer joy. The outstandingly clear layout of the body and good allround visibility, combined with the raised seating position, enhance everyday practicality and ensure relaxed driving, even in dense city traffic.

Superlative ride comfort, outstanding handling dynamics and excellent offroad performance

The AGILITY CONTROL suspension on which the Mercedes-Benz GLK-Class is founded displays a high level of flexibility and resolves a conflict of aims that particularly affects the SUV class, where chassis engineers want to create a vehicle that is both sportily agile and comfortably smooth yet one which can also cope with off-road terrain. If the focus is on sporty, active handling, the suspension and, above all, the shock absorbers need to display a certain firmness, which precludes access to the brand's typical suspension comfort and limits the off-road options. If the vehicle is set up with softer dampers to ensure suspension comfort and off-road capability, dynamic handling naturally suffers. The solution is "amplitude-dependent damping". In this system, the damping forces of the shock absorbers are configured to respond flexibly rather than lineally. In normal driving mode on moderately contoured roads or during slow off-road manoeuvres, the system responds softly, enhancing both the occupants' comfort and the vehicle's off-road capability. To ensure that this level of comfort is maintained when driving hard or performing abrupt evasive manoeuvres, in these situations the dampers deliver a harder performance, ensuring optimum handling stability. At the same time, the driver of the GLK is supported by speed-sensitive power steering, specified as standard for the V6 models, which provides the optimum level of steering assistance for the situation in hand. Parking and off-road manoeuvring are made much easier because maximum power assistance is available. At higher speeds, the assistance is reduced in favour of greater handling stability.

All the base models in the GLK series are fitted with 17-inch, size 235/60 R 17 light-alloy wheels. In conjunction with the exterior sports package, which is included as standard when the car first comes onto the market, or the off-road styling package, all models are shod with mixed-size tyres which, together with the AGILITY CONTROL suspension and the asymmetric power distribution between the front and rear axle, form the basis for a even better transfer of power between the wheels and the road. And the more effective this power transfer, the less frequently the electronic control systems need to intervene. The road-oriented exterior sports package features size 7.5 J x 19 light-alloy wheels with 235/50 R 19 tyres at the front and size 8.5 J x 19 wheels with 255/45 R 19 tyres at the rear. If the GLK is ordered with the off-road styling package, the front axle has size 7.5 J x 17 light-alloy wheels with 235/60 R 17 tyres, while the rear axle features size 8.0 J x 17 wheels with 255/55 R 17 tyres. All models are equipped with a TIREFIT system for repairing tyre damage. A compact spare wheel, which can be used on the front or rear axle, is available as an optional extra.

4MATIC: high-performance all-wheel-drive system with sophisticated control systems

The 4MATIC powertrain at the heart of the Mercedes-Benz GLK-Class is one of the most capable all-wheel-drive systems on the market. The driving dynamics systems ESP®, ASR and 4ETS are superbly harmonised with each other; when they go into action their quality of control is so good that top-notch longitudinal and lateral dynamism coupled with superb handling stability are ensured under all conditions, both on and off-road. Thanks to the compact, lightweight and frictionoptimised concept, with a longitudinally installed engine and block-design main transmission and transfer case, the system offers various advantages over its counterparts equipped with a transversely installed drive unit. Fuel consumption, for example, is about on a par with that of a comparable conventionally powered vehicle, while the minimal vibration and noise levels rival those of today's luxuryclass models.

The 45:55 percent basic distribution of the drive torque between the front and rear axle - along with the ESP®, ASR and 4ETS dynamic handling control systems - ensures effortless and predictable performance in all conditions. Optimum traction, maximum driving stability and superlative handling are assured at all times. When tuning the control systems, the engineers at the Mercedes-Benz Technology Center (MTC) made neutral self-steering behaviour a top priority. Only when the physical limits of driving are neared is there a slight oversteer tendency. All GLK models display these characteristics, even if road conditions vary widely. Whether it be dry or wet. On snow, ice or unsurfaced roads. If drivers never know whether to expect understeer or oversteer, they become unsure. This problem - a frequent occurrence in the SUV category - is solved once and for all by the Mercedes-Benz GLK-Class. The newly developed multi-disc clutch in the centre differential supports the system if the friction between the tyres and the road surface is particularly low, for example on snow or ice. A basic partial locking torque of 50 newton metres between the front and rear axle produces a significant increase in traction whilst the high level of directional stability is maintained.

The "G" button on the centre console makes the GLK with off-road engineering package even more assertive on rough terrain. Pressing the button activates a special driving program which varies the shift points of the 7G-TRONIC transmission, "softens" the accelerator pedal characteristics and activates the ESP® off-road function. In this mode the system is designed to operate with a higher degree of wheel slip while retaining directional stability. This control strategy improves traction off-road, particularly on low-friction surfaces such as sand, gravel or stone chippings. There is also a manual transmission mode, in which the shift paddles on the steering wheel can be used to change between the gears. A further switch activates the Downhill Speed Regulation (DSR) system, which automatically maintains a pre-programmed speed on steep downhill inclines. The off-road-specific body dimensions are equally impressive. The large ground clearance of 201 millimetres (GLK 280 4MATIC) and the short body overhangs (front 816 mm, rear 957 mm) make for favourable angles of approach and departure - 23 degrees and a maximum of 25 degrees, respectively. Meanwhile the relatively short wheelbase length of 2755 millimetres and the vehicle weight of 1830 kilograms, which is remarkably low for an SUV, allow the GLK to make good headway on even the most topographically demanding of terrain.

As well as a tyre pressure loss warning system, the tried-and-tested Electronic Stability Program (ESP®) for the GLK incorporates a vehicle/trailer stabilisation function, which defuses critical driving situations involving a trailer before they become dangerous by applying the individual wheel brakes as and when required. The towing capacity is 2000 kilograms.

Effortlessly superior: new four-cylinder diesel engine and proven V6 powerplants

State-of-the-art powerplants ensure an exceptionally high level of ride comfort and impressive performance right across the GLK range. Plus fuel-consumption figures are low, as is the emission count. Customers have a choice of four model variants: diesel aficionados can opt for the GLK 220 CDI BlueEFFICIENCY or GLK 320 CDI, while those with a preference for petrol can select the GLK 280 or GLK 350, both of which feature a V6 powerplant.

In the GLK 220 CDI BlueEFFICIENCY, the all-new diesel engine generation posts an excellent set of figures. Like the V6 unit in the GLK 320 CDI, the four-cylinder engine with a displacement of 2.2 litres and an output of 125 kW/170 hp reflects the dynamism of the GLK concept as a whole and produces impressive performance coupled with lower fuel consumption and reduced emissions. Torque is equally impressive, with some 400 newton metres available across a broad engine speed range of 1400 to 2800 rpm. Technical highlights of the exceptionally compact and smooth-running CDI powerplant with rear camshaft drive include fourth-generation common-rail direct injection with an injection pressure of 2000 bar and a two-stage turbocharger system. The state-of-the-art powerplant propels the GLK from 0 to 100 km/h in just 8.8 seconds and on to a top speed of 205 km/h. The compression-ignition engine with extremely low untreated emissions delivers exceptional environmental performance and, like all diesel engines for Mercedes passenger cars, features exhaust gas recirculation, an oxidising catalytic converter and a maintenance-free diesel particulate filter as standard. In addition, the engine developers have succeeded in reducing untreated emissions by a decisive margin. The smooth-running four-cylinder unit consumes a mere 6.9 litres of diesel per hundred kilometres, emits just 183 grams of CO2 per kilometre and already meets the requirements of the EU5 emission standard. The diesel line-up is augmented by the proven V6 powerplant in the GLK 320 CDI, which develops 165 kW/224 hp and achieves a peak torque of 540 newton metres, enabling the GLK to perform even more admirably: here the top speed is 220 km/h whilst acceleration from 0 to 100 km/h takes just 7.5 seconds. The V6 engine also features exhaust gas recirculation, an oxidising catalytic converter and a maintenance-free diesel particulate filter. Diesel consumption is a mere 7.9 litres per hundred kilometres. Plus the engine complies with the Euro 4 standard.

The two smooth-running V6 petrol models - the GLK 280 and the GLK 350 - develop 170 kW/231 hp and 200 KW/272 hp respectively, all of which makes for rapid performance. Yet fuel consumption is only moderate. The 3.5-litre V6 in the GLK 350 4MATIC stands out in particular, achieving figures similar to those of a sports car. It has a top speed of 230 km/h and races from 0 to 100 km/h in 6.7 seconds. Both engines also comply with the Euro 5 standard, consuming 10.2 litres and 10.4 litres per hundred kilometres respectively.

All of the engine variants for the GLK are matched with the 7G-TRONIC 7-speed automatic transmission as standard. But the exceptional performance and low fuel consumption are not just down to the perfect combination of the highly sophisticated engines with the 7G-TRONIC and the friction-optimised powertrain. Further key factors include the relatively low overall weight (GLK 280: 1830 kg) and the exceptional aerodynamics for a vehicle of this design (cd figure 0.35).

Complete safety package for maximum occupant protection

In combination with the front and rear deformation zones, the GLK's highstrength passenger cell provides a highly efficient foundation for the occupant protection systems. These include:
Adaptive, two-stage airbags for the driver and front passenger
Kneebag for the driver
Front sidebags and, as an option, sidebags for the rear seats
Windowbags across both seat rows from the A-pillar to the C-pillar
NECK-PRO crash-responsive head restraints for the driver and front passenger
Crash-optimised pedal system
3-point seat belts for all five seats
Belt tensioner and adaptive belt-force limiter for the driver and front passenger, belt tensioner and single-stage belt-force limiter for the outer rear seats
ISOFIX child seat attachments
Belt height adjuster for the driver and front passenger
Belt status indicator for the rear passengers in the instrument cluster

The optionally available PRE-SAFE anticipatory occupant protection system, made available in the compact-SUV market segment for the very first time, sees Mercedes-Benz taking safety to a new, high level in this segment. The highlight of the concept is the networking between the active and passive safety systems. PRE-SAFE uses the sensors of the dynamic handling control systems - for example, Brake Assist (BAS) and ESP - and optimises the protective functions of the passive safety components in potential accident situations. The standard-fit adaptive brake lights, which flash to warn the traffic behind when the brakes are applied abruptly, help to prevent accidents.

Mercedes-Benz ML450 Hybrid

Mercedes-Benz ML450 Hybrid

In the search for the optimum hybrid system for the Mercedes-Benz ML450 Hybrid, the engineers were already sure of one thing right from the concept phase: a Mercedes-Benz SUV with a hybrid drive would have to share the same typical brand attributes as any other Mercedes vehicle. Essential elements such as the greatest possible active and passive safety, optimum ride comfort and ease of operation, uncompromising reliability over a long period and high-quality workmanship with select materials would have to be on a par with a comparable, conventionally powered standard-production vehicle. And all combined with the greatest possible efficiency. At the same time, the drive system should be testimony to the company's innovative strength and cutting-edge technology. These objectives demanded a complete development cycle - the kind of process any new model family developed from scratch would undergo. Until the Mercedes-Benz ML450 Hybrid reached series-production maturity, the engineers and technicians clocked up a total of four million kilometres, taking in some of the world's most extreme climatic conditions to prove the system's reliability, be it in the sub-zero Arctic circle, the searing heat of arid desert regions or in the sweltering, humid temperatures of the tropics. The work was supplemented by an extensive test-rig programme and detailed simulations as part of the "Digital Prototype". An important aim during development was to optimally match the various subsystems within the powertrain. System matching enables the various drive modes to be easily used while the customer is driving.


The two-mode hybrid technology in the Mercedes-Benz ML450 Hybrid, whose drive architecture supports purely electric operation and purely combustion engine operation or any combination of the two, takes its lead from the fundamental work undertaken by the "Global Hybrid Cooperation". This group brought together research and development work undertaken by the companies Daimler AG, BMW Group, General Motors and Chrysler.

Superior technology: two-mode hybrid for the most efficient drive system

Thanks to two-mode hybrid technology the Mercedes-Benz ML450 Hybrid boasts tangible benefits: its performance figures are on a par with a conventional eight-cylinder SUV with permanent all-wheel drive while fuel consumption and emissions have been reduced by up to 60%. The vehicle designed specifically for the US market delivers 'city' fuel consumption of 21 mpg and 'highway' consumption of 24 mpg, making it the most efficient vehicle in its segment. With its SULEV (Super Ultra Low Emission Vehicle) classification, the SUV meets the most stringent emissions standard for vehicles with a combustion engine currently applicable in the US. At the same time, the Mercedes-Benz ML450 Hybrid with a system output of 250 kW (340 hp) and a combined torque of 517 newton metres guarantees a superlative driving experience combined with an enhanced level of ride comfort. The driver can concentrate fully on the traffic and enjoy the Mercedes-Benz ML450 Hybrid driving experience without having to select additional functions as the drive management system is fully automatic. The functionality of the 4MATIC permanent all-wheel drive system is also fully retained.

At the heart of the two-mode hybrid drive is the transmission unit with two compact electric motors, three planetary gear sets and four clutches. This configuration enables the power to be split into an electrical and a mechanical path. Conventional one-mode hybrid systems tend not to have mechanical ratios. As such, this kind of system transfers the bulk of the power via the electrical path with high electrical output and hence lower efficiency. It works efficiently principally at lower loads and speeds. If power also needs to be transferred at higher loads and speeds, an accordingly larger electric motor would be required. Having to power and find space for this engine would only be possible at the expense of efficiency. In response to increasing engine loads and higher speeds, two-mode technology, by contrast, variably shifts the power transfer from the electrical path to the mechanical drive path. As a result, the system is much more efficient in all situations, both in inner-city stop-and-go traffic as well as on fast motorway journeys, while also enabling smaller electric motors to be used. The efficiency boost - both in urban traffic as well as on motorway journeys - is therefore where "two-mode" technology gets its name from.

The four clutches are used to distribute the driving force generated by the electric motor and combustion engine via four fixed ratios and two electric variable ratios to all four wheels on the 4MATIC permanent all-wheel-drive system, depending on the driving situation. Various strategies ensure the best possible fuel consumption and performance, depending on the traffic situation or the driver's requirements:
When moving off or at low speed up to the second fixed gear, the Mercedes-Benz ML450 Hybrid operates in ECVT 1 mode (Electric Continuously Variable Transmission), delivering a very comfortable, smooth ride.
At higher speed from the second fixed ratio, ECVT 2 mode is used. Depending on the optimum operation point, a combined or continuously variable mode is selected.
In the first and third fixed gear both electric motors work synchronously, providing either additional energy for acceleration (boost) or storing the braking and coasting energy (recuperation).
In the second and fourth fixed gear, one electric motor is switched off to improve efficiency. The second electric motor is used for the booster function and recuperation.

The two compact electric motors boast a high power density and are fully integrated into the transmission housing. The limited installation space means the two electric motors have to be configured differently. The first electric motor - positioned nearer to the combustion engine - develops 62 kW (85 hp) and 235 newton metres of torque and has been designed with power output and minimal losses firmly in mind. The electric motor placed at the end of the transmission develops 60 kW (82 hp) and 260 newton metres and is thus the ideal solution for moving off solely under electric power and providing the booster function.

Compact 288-volt battery with high power density

The electrical energy in the Mercedes-Benz ML450 Hybrid is stored in a compact, liquid-cooled high-voltage nickel-metal hydride battery.

Battery data at a glance:
Type: Liquid-cooled high-voltage nickel-metal hydride battery
Mounting location: Vehicle rear
Weight: 83 kg
Modules / cells: 24 / 240
Electrical output: 45 kW
Capacity: 2.4 kWh
Voltage: 288 V

A battery management function monitors and controls the various charge flows during electric motoring, boost or recuperation to ensure a stable charge state. The entire high-voltage onboard network complies with the most stringent safety standards.

Sophisticated management system computes the most fuel-efficient operating mode in real time

Operation of the two external rotor magneto motors and the management of the entire high-voltage onboard network requires complex control electronics housed in the engine compartment of the Mercedes-Benz ML450 Hybrid. Waste heat from the electronics is dissipated via a separate cooling circuit to increase efficiency. An integrated Auxiliary Power Module enables power to be exchanged between the 288-volt battery and the 12-volt onboard network.

A powerful computer controls the hybrid system with up to 50 million computing operations a second. The electronic control unit calculates the most efficient operating mode 160 times a second, thus ensuring the lowest possible fuel consumption. The management system also supports new functions and comfort/convenience features:
The transmission's coordinated shift strategies ensure judder-free manoeuvring
"Chill down" mode enables the battery to recover during overload or high temperatures
An adaptive drive mode learns the driving style of the driver or the particular route profile to optimise the agility of the drive mode
The "Power Launch Control" supports optimum acceleration in boost mode
The "Traffic Jam" feature enables the vehicle to be driven entirely under electric power in stop-and-go traffic even with a low battery charge status

Consumption-optimised Atkinson V6 engine

The modified 3.5-litre V6 petrol engine has been optimised in accordance with the Atkinson process, delivering substantially better fuel consumption and emissions figures with an output of 205 kW (279 hp) and a maximum torque of 350 newton metres. The development engineers utilised some of the benefits of the Atkinson principle whereby the expansion phase is longer than the compression phase. The intake valve is kept open slightly longer between the intake and compression phases, which improves the engine's thermal efficiency while reducing the specific fuel consumption and untreated emissions. This process is not used with conventionally powered vehicles because Atkinson engines - apart from the lower fuel consumption and emissions - tend to deliver lower torque at lower revs and thus inferior response particularly at low engine speeds. On the Mercedes-Benz ML450 Hybrid this drawback is more than offset through the use of the electric motors when moving off normally, accelerating or using the booster function. The M-Class thus offers superb responsiveness and agility.

Compared with the conventional 3.5-litre V6 petrol engine, the Atkinson version features a modified cylinder head, pistons and camshaft. The camshaft timing has also been modified. The newly developed regulated oil pump adjusts the flow rate to the engine's actual requirements, thus minimising the necessary delivery rate and helping reduce fuel consumption and emissions. Since the alternator and starter functions are integrated in the two electric motors, these two components, which are now surplus to requirements, no longer need to be connected up to the belt drive on the combustion engine. The air conditioning compressor and the steering servo pump are another two components that do not need to be powered via the belt drive. These are driven electrically on the Mercedes-Benz ML450 Hybrid and can be run independently of the combustion engine.

Operating strategies of the two-mode hybrid drive

The Mercedes-Benz ML450 Hybrid offers the full range of extra functions offered by a hybrid drive. These include variable hybrid mode for city and motorway driving, silent, purely electric moving off and motoring, the "booster function" for fast acceleration, recuperation and the start/stop function. These functions are activated depending on the operating state and traffic situation:
While at a standstill, the combustion engine is switched off. The air conditioning and power steering functions are fully retained thanks to the electric drive of the air conditioning compressor and the steering servo pump.
Manoeuvring, for instance when parking, only uses the electric drive.
If the driver presses the accelerator from a standstill, the Mercedes-Benz ML450 Hybrid moves off solely using electric power. If the accelerator is pressed rapidly, the management system recognises the need for increased acceleration, activates the combustion engine which it backs up with additional torque from the electric motor (booster effect). This noticeably increases the vehicle's agility without having to use the kickdown feature.
When cruising, the operation point is shifted toward lower specific fuel consumption figures to increase the efficiency of the V6 engine while in turn also increasing efficiency particularly under partial loads.
Recuperation, the conversion of braking energy into electric power and subsequent storage starts immediately the vehicle is in overrun mode or during normal braking manoeuvres. The service brake is also activated during heavy braking. The Mercedes-Benz ML450 Hybrid can match where necessary the kind of good maximum deceleration you will find on a conventionally powered M-Class with the same superb handling.
The start/stop function deactivates the V6 engine as soon as it is not needed, say when rolling up to a red traffic light. As soon as the driver presses the accelerator, the ML moves off using electric power and then starts the combustion engine.
The Silent Start enables the vehicle to be started without creating any noise.

Info display indicates current operating state

The Mercedes-Benz ML450 Hybrid driving experience offers an impressive mix of high agility and balanced ride comfort under all operating conditions. A specially designed display concept enables the driver to keep track of the particular drive mode. The COMAND system display can be used to either display the current energy flow between the high-voltage battery, combustion engine and electric motors including the percentage charge state of the battery, or a fuel consumption and recuperation energy graphic. The battery charge state can also be called up in the instrument cluster. The conventional rev counter is replaced by a display which illustrates the combined drive system and recuperation output at a given moment.

The choice is yours: Economy or Sport mode

To ensure you can experience the extraordinary agility of the Mercedes-Benz ML450 Hybrid even more emphatically, apart from Economy mode, the model comes with a Sport mode, which is activated using the "E/S" button in the centre console. This operating mode provides the handling of a conventional automatic transmission with eight fixed ratios and very short shift times. The response is even more spontaneous thanks to the decidedly sporty engine and transmission control unit and the direct through-drive in the powertrain. Sport mode also recognises the driving characteristics of the driver or the particular road profile and adapts the system management function accordingly.

Classic benefits of the M-Class remain unchanged

The Mercedes-Benz M-Class models rank among the most successful premium SUVs and offer the greatest possible active and passive safety, optimum ride comfort and ease of operation, uncompromising reliability over a long period and high-quality workmanship with select materials. These attributes naturally also apply to the Mercedes-Benz ML450 Hybrid, which in these respects offers performance on a par with the conventionally powered variants. The hybrid version meets the same crash requirements and offers outstanding active safety thanks to the dynamic handling control systems ESP®, ABS or BAS and the 4MATIC permanent all-wheel-drive system. The hybrid technology has been integrated perfectly, without taking up any additional installation space which would compromise comfort or practicality. The space in the passenger compartment is unchanged; the boot capacity is as large as ever. The only external clues on the Mercedes-Benz ML450 Hybrid are the redesigned bonnet, the BlueEFFICIENCY label on the wings and the HYBRID lettering on the rear.

The Mercedes-Benz ML450 Hybrid is produced at the Mercedes-Benz plant in Tuscaloosa, Alabama, in the United States.
