Overview

First-class on and off-road

Mercedes-Benz is unveiling a new highlight in the luxury Sports Utility Vehicle market segment: the GL-Class. The seven-seater premium off-roader offers excellent handling both on and off-road and pampers occupants with its extremely spacious accommodation and the comfort of a luxury saloon. The GL-Class sets another milestone with the PRE-SAFE® safety system, a first in this market segment.

With its poised, assured presence, the GL-Class leaves one in no doubt about its aspirations to conquer this market segment. The distinctive design idiom exudes power and exclusivity. Calm body surfaces, powerful, wedge-shaped features and striking details give the impression the luxury off-roader is surging forward even when stationary. The spacious body (length 5088 mm, width 1920 mm, height 1840 mm) is beautifully proportioned.

Superlative comfort whatever the conditions

The welcoming interior with its top-quality materials provides passengers with that feel-good atmosphere as only Mercedes knows how, with more than ample space for up to seven people. The GL-Class offers superb comfort on board - whether you're just popping into town, cruising hundreds of kilometres or negotiating rough terrain. Occupants still enjoy good freedom of movement even on the two full-sized individual seats in the third row of seats. The distance to the middle row of seats is 815 mm, with 979 mm headroom for passengers. If fewer seats are required, the rear individual seats can be stowed electrically at the push of a button, either individually or in tandem to provide a completely flat load surface. The luggage compartment capacity amounts to 1240 litres in the five-seater version. The GL-Class can provide up to 2300 litres of load capacity, with the load compartment measuring 2128 mm in length. In line with the wide range of applications handled by the versatile all-rounder, the THERMATIC automatic climate control system fitted as standard in the GL 320 CDI provides consistent temperature for all seven seats both in the depths of winter and on those sweltering summer days. The versions with V8 engines such as the GL 420 CDI, GL 450 and GL 500 come with the standard-fit multi-zone THERMOTRONIC system, which offers even more climatic comfort. Other standard-fit convenience and comfort appointments include ARTICO man-made leather upholstery combinations, electrically adjustable front seats and a fixed rear glass roof above the third row of seats.

Intelligent solutions promote excellent safety

The GL-Class makes full use of the advantages of its unitised body, combining optimum strength with intelligent lightweight steel design. The result is excellent passive safety. Combined with the front and rear deformation zones, the high-strength occupant cell forms an efficient base for the occupant protection systems that include:

With the optionally available PRE-SAFE® preventive occupant protection system, a world first in this market segment, Mercedes-Benz has raised safety to an even higher level. The system's most striking feature: passive and active safety systems are networked with each other. PRE-SAFE® utilises the sensors in the dynamic handling control systems such as ABS, BAS (Brake Assist) and ESP® and optimises the protective function of the passive safety components in potential accident situations. The GL-Class also takes the issue of pedestrian protection to a new level. The front section includes precisely defined ample crumple space between the body and the major assemblies underneath. In conjunction with impact zones that are designed to yield, this design provides a high degree of protection both for pedestrians and cyclists.

The GL-Class meets all the requirements of a state-of-the-art, luxury SUV and even redefines them on a higher level. Yet the hallmark Mercedes off-roader genes such as superlative robustness, ruggedness and long-term durability have not been compromised. It is not without reason that the model designation echoes the legendary precursor of all Mercedes-Benz off-road vehicles - the G-Class. The evergreen off-roader is now in its 27th year of production and will continue to be marketed alongside the new GL-Class.

Outstanding handling on and off-road

4MATIC - the permanent four-wheel drive from Mercedes-Benz - provides the GL-Class with superior handling whatever the conditions. Together with the standard-fit AIRMATIC air suspension, the precise speed-sensitive power steering and the ADS Adaptive Damper System also fitted as standard, the imposing GL-Class (wheelbase 3075 mm) handles impressively. Handling, when pulling a trailer is no less impressive thanks to ESP® Trailer Stabilisation. It defuses critical driving situations involving a trailer before they become dangerous by precisely applying the brakes, while AIRMATIC provides fully automatic level adjustment.

Special off-road features such as Downhill Speed Regulation (DSR), hill-start as-sist and off-road ABS assist the GL-Class driver off road. The Off-Road Pro engineering package, standard on all ECE models, means the GL-Class can also handle the most extreme off-road terrain. This includes a two-speed transfer case with a low range ratio and 100 percent differential locks for the transfer case and the rear axle. The modified AIRMATIC air suspension, designed specifically for the more demanding conditions, increases the ground clearance to a maximum of 307 millimetres where required, and raises the fording depth to 600 millimetres.

Majestic drive systems: new V6 and V8 engines

The ultra-modern engine line-up in all GL-Class models provides superlative drive comfort and compelling performance coupled with superior fuel consumption figures compared with other vehicles in the class. Alongside the 165-kW/224-hp V6 engine in the GL 320 CDI, the range of diesel models includes the new-generation high-performance V8 diesel in the GL 420 CDI, which now has an output of 225 kW/ 306 hp and maximum torque of 700 Nm. Both diesel-powered versions undercut the EU 4 limits and feature a maintenance-free diesel particulate filter. In addition to the newly developed 5.5-litre, 285-kW/388-hp engine in the GL 500, launched earlier in the new S-Class, the second unit in this ultra-modern V8 family of engines is celebrating its world premiere in the GL-Class. In the GL 450 the 4.6-litre engine develops 250 kW/340 hp. Both engines also fulfil the stringent EU4 limits (USA: LEV II standard).

All GL-Class engine variants come with the 7G-TRONIC seven-speed automatic transmission with DIRECT SELECT as standard. Excellent performance and low fuel consumption result from the perfect combination of ultra-modern engines with 7G-TRONIC and the friction-optimised powertrain. Another important factor is the comparatively low gross vehicle weight thanks to the unitised body and the excellent aerodynamics (Cd 0.37) for such a large vehicle.

Success story from state-of-the-art production facilities

"Mercedes Quality - Made in the USA" has established itself as the company's new trademark on the other side of the Atlantic and illustrates the success story of the DaimlerChrysler plant in Tuscaloosa/Alabama. The birthplace of the GL-Class started production in 1997 as the first Mercedes-Benz plant outside Europe. Around 600 million US dollars have been invested since 2001 in expanding and constantly modernising the plant; overall the company has invested around 1 billion US dollars. Following the extension of the Tuscaloosa plant in May 2005, its theoretical annual production capacity for all model series stands at 160,000 units. The new GL-Class is now the third model series to be built here, alongside the M-Class and the R-Class.

The world premiere of the new Mercedes-Benz GL-Class takes place at the North American International Auto Show (NAIAS) in Detroit in January 2006. U.S. customers will be the first to savour the delights of the new trendsetter in the spring; European customers will have to wait until September 2006 for a taste of the versatile off-roader.

Body, interior and climate control: Feel-good atmosphere in a class of its own

Attractive and impressive interior design, vast amounts of space, excellent seating ergonomics and automatic climate systems allow up to seven occupants to travel in first-class comfort, whether on short trips about town, on long-distance tours or driving off-road. The upscale equipment and the strongly appealing interior architecture, with its genuine wood trim and leather-upholstered dashboard, all help to create a typical Mercedes-Benz atmosphere of comfort and congeniality. At the same time a stiff, high-strength body structure provides a firm foundation not only for high standards of passive and active safety but also for comfort-enhancing low noise and vibration levels.

The external and internal dimensions shown below are a good indicator of the spaciousness offered by the new GL-Class. The corresponding figures for the R-Class are shown side-by-side for comparison:

As the comparison shows, the spaciousness of the GL-Class is comparable to the spaciousness offered by the R-Class's "dynamic space concept". Occupant room in the third seat row is particularly good.

Electrically adjustable seats as standard

The GL-Class features electrically adjustable front seats and a manually adjustable multifunction steering wheel as standard. Extensive adjustment possibilities mean that occupants of all sizes can select an ergonomically optimal seating position. At the press of a button on the outer side of the seat cushion, the seats can be adjusted for fore-and-aft position, height, cushion angle and backrest angle. The driver's seat has a manually adjustable lumbar support. The head restraints are manually adjustable. Both front seats offer an excellent balance between good lateral support and superior springing and damping. One example: in the side bolsters, firmer foam plastic is used to provide good lateral support under heavy lateral acceleration, while in other areas a softer compound is used, to provide outstanding comfort. The V8 versions – the GL 420 CDI, GL 450 and GL 500 – are equipped as standard with electrically adjustable seats with memory function and electrically adjustable steering column. Optionally, comfort can be taken even further, with multicontour seats. As an alternative to the standard "ARTICO" seat upholstery, leather or nappa leather upholstery is also available. On the top-of-the-line GL 500, nappa leather is standard.

Centre-row bench seat and third-row individual seats in rear

The centre-row bench seat with four-way backrest adjustment provides high seating comfort for up to three passengers. The wider section of the 1/3:2/3 split-folding seat has a folding armrest with cup holder and compartment. The back-rests and the cushions can both be folded down, for transporting bulky loads: the divided seat cushion folds forwards in individual sections, then the backrests are folded forwards to create a flat surface level with the load floor at the rear. The outstanding loading dimensions of the GL-Class are shown below, again alongside the corresponding figures for the spacious six-seater R-Class:

A newly developed EASY-ENTRY system provides convenient access to the optional third-row individual seats. To use this facility, the narrower backrest section of the bench seat is released and folded forward together with the cushion. If the front passenger seat is in a further back position, it automatically slides forward. When the third-row passengers have taken their seats, the bench seat can be folded back into position and the front passenger seat returns to its original position.

Equipped with the third-row individual seats, the GL-Class is a full-size seven-seater. Either one or both seats can be electrically folded to create a continuously level load floor which, when the centre seat row is folded down as well, extends right the way through to the front seat backs. Customers who do not opt for the seven-seater version get an additional stowage compartment under the load compartment floor. A fixed panoramic sunroof over the third-row seats, which is equipped with a sunblind, provides additional comfort and enhances the sense of spaciousness. There are integral armrests in the sidewall trim and a cup holder is fitted on either side. The optional rear-seat entertainment system, comprising two colour monitors with headphone jacks in the back of the front head restraints and a CD/DVD player under the centre bench seat, allows rear-seat passengers in the GL-Class to listen to or watch their own choice of music or films. To extend the entertainment programme even further, external audio/video sources or a games console can be connected to the system.

The proven EASY-PACK system makes for easier loading and unloading and secures the cargo. A load compartment cover and a safety net, which attaches behind the front seats or behind the centre bench seat are standard on all GL models, together with eight load-securing rings. Optionally, a hydraulically operated tailgate with remote control can be supplied, or a floor-anchored EASY-PACK load-securing kit.

A pleasant climate and good entertainment

Since this adaptable and multi-talented vehicle is designed for very varied applications, the GL 320 CDI is equipped as standard with the THERMATIC automatic climate control system, to ensure that all seven occupants can enjoy a pleasant climate on board even in arctic cold or in tropical heat. The diesel models are equipped with a 1.7-kilowatt heater booster to provide quick warmth in cold weather. THERMATIC offers dual-zone temperature control for driver and front passenger, a continuously variable fan speed and automatic variable air recirculation, for more effective cooling. The V8 models – GL 420 CDI, GL 450 and GL 500 – are equipped as standard with the multi-zone THERMOTRONIC climate control system, which takes climate comfort to a new level, with separate temperature controls for passengers in the rear. The rear section is also equipped with its own booster. In conjunction with the multi-zone THERMOTRONIC, a rear air condition-ing unit can also be supplied, for further enhanced cooling in the second and third seat rows.

A variety of audio systems offer highest standards of information, communication and entertainment. The Audio 20 radio with CD player, eight speakers, monochrome display and mobile phone pre-installation with telephone keypad is standard specification. The Audio 50 APS model adds a CD navigation system and a colour display. The top-of-the-line COMAND APS system with integrated radio, CD/DVD player, DVD navigation, telephone operation, colour display and off-road menu is combinable with a TV tuner and a reversing camera. All audio systems can be upgraded with a surround sound system with eleven speakers and a sub-woofer to recreate a concert hall sound experience.

Body – long life and top-class aeroacoustics

A stiff body structure provides the basis for comfort-enhancing low noise and vibration levels in the GL-Class. Strength is maximised by structural reinforcements which include an X-shaped underfloor reinforcement and a so-called "D" ring. At the rear, behind the large tailgate, the body ends in a hoop-type structure resembling a fuselage bulkhead as used in aircraft production. This "D" ring connects the rear roof rail with the sidewalls and the floor structure, and provides significantly improved torsional stiffness and dimensional stability. At the body-in-white stage, 17 noise-insulating foam elements are installed in each sidewall. Further noise reduction is provided by careful sealing of all seams and flanges.

The low wind noise levels in the GL are unsurpassed in this class. Smooth airflow over the body, the optimised shape of the exterior mirrors, improved airflow around the A-pillar and the double or triple seals on the doors all help to reduce wind noise to a minimum. The windows play their part as well: the windscreen is 5 mm thick and the side windows 4.1 mm thick.

The fully galvanised body and further corrosion-proofing measures such as cataphoretic immersion coating, cavity preservation, seam sealing and localised use of steel panels with additional coating in areas particularly at risk from corrosion help to ensure a long service life and maximum value retention. They are the basis for the 30-year corrosion perforation warranty which forms part of the standard MobiloLife warranty. Further corrosion protection is provided by the six-part plastic underside panelling and a nano-particle clearcoat which is more scratch-proof than conventional paintwork and thus ideal for an off-road vehicle.

Active and passive safety: Safety first

Exemplary passive occupant protection and outstanding active safety give the GL-Class a decisive edge. The high-performance off-roader makes full use of the advantages of its unitised body, combining optimum strength with intelligent lightweight steel design. The result is excellent passive safety. Combined with the front and rear deformation zones, the high-strength occupant cell forms an efficient base for the occupant protection systems, meaning that the GL-Class has the potential to achieve maximum ratings in both US and European NCAP crash tests.

World premiere: PRE-SAFE® makes its debut in this vehicle category

The luxurious off-roader is the world's first seven-seater to feature the innovative PRE-SAFE® preventive occupant protection system, available as an optional extra. The most striking aspect of the system, first introduced by Mercedes-Benz in the S-Class in 2002, is the fact that the active and passive safety systems are networked with each other. PRE-SAFE® utilises the sensors in the dynamic handling control systems such as ABS, BAS (Brake Assist) and ESP® (Electronic Stability Program) and diagnoses critical handling situations which can potentially lead to an accident. This is the case when Brake Assist is activated during emergency braking situations or when, despite the intervention of ESP®, it is no longer possible to stabilise the vehicle, since this is beyond the bounds of physical possibility. If such a situation is detected – this detection takes place within a matter of milliseconds – the system optimises the level of protection provided by the passive safety components and prepares the occupants and the vehicle for a possible collision. If necessary, the driver and front-passenger seat belts are tensioned whilst the optionally available, electrically adjustable front-passenger seat with memory function is moved into an optimal position to allow the airbags and seat-belt system to deploy to maximum effect. In addition, the system closes the sliding sunroof and side windows as a precaution. If the collision is avoided and the dynamic handling limits are not reached, the seat-belt tensioners are released automatically. The front-passenger seat, side windows and sliding sunroof can then be returned to their original positions.

Outstanding passive safety for seven occupants

People travelling in the GL-Class are protected by a comprehensive restraint system which, as well as the PRE-SAFE® components described above, also includes the following features:

One of the key safety components is the electronic control unit which activates the restraint systems based on signals received from a sophisticated sensor system, including the central crash sensor on the vertical axis of the vehicle, two additional up-front sensors in the radiator cross-member, two lateral accelerometers below the B-pillar and two satellite pressure sensors in the front doors. If the optional sidebags for the middle seat row are specified, the rear doors are also equipped with satellite pressure sensors.

Thanks to this extensive sensor system and the calculations that are performed centrally within a matter of milliseconds, the airbags and seat-belt systems are able to provide far more effective occupant protection. If the up-front sensors detect a frontal collision, for example, the new crash sensors compare the received data with the data provided by the central crash sensor on the centre tunnel and, if the impact is deemed severe enough, trigger the front airbags and the seat-belt tensioners. Since the up-front sensors detect the impact at an earlier stage, the airbags and seat-belt tensioners can be activated sooner. This configuration has major advantages. After all it still holds true that the earlier the occupants take part in the vehicle's overall deceleration, the higher the level of protection that can potentially be provided by the restraint systems. But the crash sensors do far more than this. If the system detects an accident of moderate severity, only the first stage of the adaptive airbags is deployed. However, if the impact is more severe, the second stage of the airbag is also fired after a slight delay. This means that the driver and front-passenger airbag can provide the optimal degree of protection for a wide range of impact scenarios.

The sophisticated sensor system also supports the activation of windowbags and side airbags. In this case the data provided by the central crash sensor are compared with the lateral acceleration data recorded by the side sensors below the B-pillar and the information sent by the pressure sensors in the doors. Based on these data, the system control then calculates the optimal activation strategy within a matter of milliseconds. In addition, the command centre has access to a roll-over sensor. In certain roll-over situations, all the belt tensioners and both windowbags are activated. The windowbag itself has a special coating and is filled by a helium gas generator, thus ensuring a longer service life and, as a consequence, a higher level of occupant protection.

The crash sensors also control the optionally available NECK-PRO crash-responsive head restraints. If the system detects a rear impact of sufficient severity, it activates the head restraints, which provide support for the heads of the driver and front passenger at an earlier stage and reduce the risk of upper spinal column injuries.

Unitised body with high protection potential

Having dispensed with the frame-type design that is more usual in this vehicle category in favour of a unitised steel body, the Mercedes-Benz development engineers were faced with a new challenge. On the one hand, the vehicle had to retain the typical benefits of a frame-type design such as robustness and durability under tough off-road conditions. On the other hand, the specifications book also called for a relatively lightweight design and outstanding passive protection potential on a par with Mercedes-Benz saloon cars. The engineers were able to surmount this challenge through intelligent use of high-strength steels and a clever lightweight steel design. Some 54 percent of the GL bodywork is made from high-strength steel. Even thermoformed ultra-high-strength steel was used in some areas.

The unitised steel body forms the ideal base for the passive occupant protection systems. An extremely robust passenger cell surrounds the occupants like a protective cocoon. Its basis is a three-piece floor assembly with a centre section made of thicker material which forms a sturdy backbone. This central assembly is further stiffened by a thick-walled, X-shaped tunnel reinforcement. Lateral stability and, therefore, the survival space in the event of a side collision, is assured by side members in the front seating area and a central seat cross-member that has been reinforced using thermoformed ultra-high-strength steel. In addition, a robust diagonal member is used to strengthen the body from the firewall to the point of intersection between the side member and the B-pillar. A tubular cross-member, which also serves as a load-bearing structure for the dashboard, is bolted to the two A-pillars, the tunnel, a structural reinforcement below the wind-screen and the firewall, making the front of the passenger cell even more rigid.

The extremely sturdy side section of the body essentially comprises two components, namely the inner side wall and the outer side wall. Overall stiffness and rigidity are determined by structures including:

Like the rear seat cross-member, the A and B-pillars have reinforced areas made from thermoformed ultra-high-strength steel.

The rear area incorporating the third row of seats is designed to provide the highest possible level of protection for the rear passengers in the event of a rear impact. The design of the rear side members is based on a continuous closed cross-section and graduated material thicknesses. By adopting this approach, the designers were able to ensure greater solidity whilst also enhancing energy absorption and improving deformation behaviour. Further rigidity is provided by the recess for the spare wheel and an equally high-strength, solid cross-member that also serves as a load-bearing structure for the individual seats in the rear.

The front and rear ends, by contrast, are designed to absorb as much impact energy as possible in the event of a collision. The impact-absorbing front-end structure consists of the two longitudinal members, which are reinforced by two shells on the inside, and two longitudinally-aligned members on the outside, which are braced by the A-pillars in the event of a crash. If an offset crash occurs, the solid firewall cross-member below the cowl has an important role to play in that it distributes the impact forces to the side of the vehicle not involved in the impact, thus improving energy absorption. The bolted front end forms the front cross-member which also transfers impact energy to the side of the vehicle not involved in the impact in the event of an offset frontal crash. It consists of a two-shell sheet-steel structure, which houses the headlamp units, a two-shell radiator cross-member, a flexible aluminium member and two crash boxes which deform in order to absorb all of the impact energy at impact speeds of up to 15 km/h. These boxes are easily replaced, thus simplifying accident repairs. Repairs are also made easier by the fact that the front-end components are bolted together. Like the front end, the rear section also features a flexible aluminium member which is bolted to the rear structure by means of two steel crash boxes.

Together with the steering gear and the engine/transmission assembly, the front axle is mounted on an extremely stiff subframe which is connected to the body by means of four rubber mounts. Just like the rear axle subframe, it deforms in order to absorb impact energy in the event of a collision. To further improve durability under the toughest of driving conditions, the bodywork engineers have strengthened the subframe mountings in specific areas. The triple connection points ensure a reliable and durable connection, even during continuous operation under tough off-road conditions.

Active safety for all conditions

Whereas the passive safety systems ensure the highest possible level of occupant protection during and after an accident, the active safety features play a preventive role. Key aspects which contribute to the high degree of active safety provided by the GL-Class include an outstanding level of driver-fitness safety and exceptional ergonomic design as well as a comfort-oriented chassis offering excellent directional stability, precise speed-sensitive power steering, high-performance brakes and, last but not least, the sophisticated 4MATIC all-wheel drive system. Standard-fit dynamic handling control systems such as ESP®, the 4ETS traction control system developed especially for all-wheel drive, ABS and Brake Assist (BAS) further optimise the level of active safety, as do the standard-fit AIRMATIC air suspension and the Adaptive Damping System (ADS). Active safety is additionally enhanced by powerful headlamps and the adaptive brake lights.

The latest version of the tried-and-trusted Electronic Stability Program (ESP®) includes additional components such as ESP® Trailer Stabilisation and a tyre pressure loss warning system. The ESP® Trailer Stabilisation defuses critical driving situations involving a trailer before they become dangerous by applying individual wheel brakes as required. Even when pulling the maximum trailer load of 3,500 kg, the GL-Class models prove exceptional towing vehicles: alongside ESP® Trailer Stabilisation, the extremely rigid body, the automatic level control feature of the AIRMATIC system, the 4MATIC all-wheel drive system and the long wheel-base length ensure safe and reliable handling when towing, even in adverse conditions such as crosswinds or when the road surface has ruts caused by heavy trucks. As is the case during normal operation, Brake Assist (BAS) and the tyre pressure loss warning system have a positive effect, warning the driver if one or more tyres loses pressure by flashing up an unambiguous "Tyre pressure – check tyres" message on the central display. Optional extras include a tyre pressure monitoring system which monitors the precise tyre inflation pressure sequentially and specifically indicates any tyres that are not as they should be.

The high-performance lights, including H7 projection-beam headlamps and fog lamps, relieve driver stress when driving in twilight, in the dark or in fog. Bi-xenon headlamps with the Active Light System and a cornering light function, available as an optional extra, further enhance visibility. Additional standard equipment includes adaptive brake lights. In the event of abrupt braking manoeuvres or emergency braking during which BAS intervenes at speeds above 25 km/h, the control unit activates the three brake lights in flashing mode. If this activation takes place at speeds above 70 km/h, the brake lamps display a steady light after the vehicle comes to a halt. In this case, the control unit also activates the hazard warning lights. If the driver then accelerates again, the hazard warning lights are deactivated automatically once the speed exceeds 10 km/h. This is because, according to research carried out by the BAST organisation (German Highways Agency), a flashing brake light is noticed more quickly by other drivers, so the stopping distance of the vehicles behind is shortened considerably in dangerous situations. This in turn reduces the risk of rear-end collisions or motorway pile-ups.

Drive system and chassis: Top performance whatever the conditions

High-torque, combustion-optimised drive units and a chassis that delivers out-standing handling and exceptional ride comfort whatever the conditions make the GL-Class as highly impressive on-road as it is off-road.

The engine line-up features four state-of-the-art powerplants that play a key role in enhancing driving enjoyment thanks to their harmonious torque and power delivery. Both direct-injection diesel engines in the GL 320 CDI and GL 420 CDI models comply with the latest EU 4 emission standards and feature a maintenance-free diesel particulate filter, fitted as standard, which reduces particulate emissions by a further 99 percent without the need for additives. The tried-and-trusted V6 diesel unit in the GL 320 CDI model has an output of 165 kW/224 hp and an impressive peak torque of 510 Nm, which is available across a broad engine speed range. The result is a highly respectable set of performance figures: the GL 320 CDI accelerates from 0 to 100 km/h in 9.5 seconds, reaches a top speed of 210 km/h and consumes a mere 9.7 l per 100 km.

The new-generation V8 diesel powerplant in the GL 420 CDI model, with four valves per cylinder and twin turbochargers and variable nozzle turbines (VNT), makes the off-roader an even more spirited performer. Peak torque in the 4.0-litre engine has been boosted to 700 Nm, while modification measures have enabled the output to be increased from 184 kW/250 hp (ML 400 CDI) to 225 kW/306 hp. Furthermore, untreated emissions, fuel consumption and noise levels have been reduced. The increase in power is mainly down to the third-generation common-rail high-pressure injection system with max. 1,600 bar injection pressure and the raising of the ignition pressure to 175 bar. In addition, optimised flow conditions improve the gas cycles whilst the two newly developed VNT turbochargers operate even more effectively. Emissions have been cut drastically thanks to up to five diesel injections per injection process, special orifice nozzles, new piezoelectric injectors with more precise injection times and a modified exhaust gas recirculation system. By installing an optimised chain drive, a rigid crankcase with large engine mounts and additional acoustic covers, the engine developers were able to reduce noise levels significantly. The square bore/stroke ratio and a balancer shaft which rotates in the opposite direction to the crankshaft ensure out-standingly smooth operation. From a standing start, the GL 420 CDI sprints to 100 km/h in 7.2 seconds, its immense forwards thrust propelling it to a top speed of 230 km/h. Yet fuel consumption comes in at a relatively low 11.3 l per 100 km.

In addition to the newly developed 5.5-litre, 285-kW/388-hp engine in the GL 500, launched earlier in the new S-Class, the second unit in this ultra-modern V8 family of engines is celebrating its world premiere in the GL-Class. In the GL 450, the 4.6-litre engine develops 250 kW/340 hp, enabling the luxury off-roader to deliver scintillating performance similar to that of models fitted with the V8 CDI engine: the sprint from 0 to 100 km/h takes 7.6 seconds, while the top speed is 235 km/h. The GL 500 is even keener to provide power when requested to do so, accelerating from 0 to 100 km/h in 6.6 seconds, which is almost in sports car territory. The same can be said for the top speed of 240 km/h. Yet the GL 500 still returns a highly impressive fuel consumption figure of 13.8 l per 100 km, especially given that its kerb weight is 2,445 kg.

Technical highlights of the new V8 aluminium engines include four valves per cylinder, with continuous intake and exhaust camshaft adjustment, and an intake bridge with variable intake manifold. In contrast to conventional systems, in which only the length of the entire intake tract is varied in order to optimise the power output, the module here switches cylinder-selectively. Further cylinder-selective components used include electropneumatically driven tumble flaps which increase the flow speed in the partial-load range and therefore improve tumbling of the fuel/air mixture in the combustion chamber. As a result, combustion is improved considerably whilst power output is also boosted. As well as focusing on higher engine output and a reduction in exhaust emissions and fuel consumption, development work centred on improving comfort levels. The power-plant engineers optimised both engine refinement and the noise levels by modifying the crankshaft bearings, for example. The widened crankshaft bearing shells are no longer fixed by individual bearing brackets in the engine block but by one rigid mounting plate per cylinder bank. This cross-bolting technique also makes the entire engine block sturdier. The cylinder head cover with integrated camshaft bearings has a similar stabilising effect. Further measures implemented to enhance comfort include the use of lightweight pistons and conrods, which reduce the moved masses and therefore vibrations, and the installation of larger engine mounts to connect the engine to the subframe. Both engines undercut the stringent EU 4 emission limits (LEV II standard in the US).

Thermal optimisation as a result of extensive computer simulations

Thermal protection of the vehicle is proving an increasingly stiff challenge for engineers because of a conflict of aims. On the one hand the engine, transmission and auxiliary units require a sufficient supply of air in order to ensure thermal operational reliability at all times, even under the toughest of conditions. On the other hand experts in the field of acoustics and aerodynamics insist on encapsulating the engine as much as possible. There is also the high level of additional equipment to consider. After all, more and more auxiliary units are being installed in the engine compartment. One solution that ensures a high level of thermal protection is the use of detailed computer simulations to supplement extensive field testing.

Firstly the entire engine chamber, including all units, and the surrounding body, including all cooling air apertures, is simulated based on CAD data. Secondly further parameters such as the potential surface temperatures and dissipation energies of all components are added. Then the system "tests" the GL-Class specification concerned and simulates extremely demanding driving conditions, including prolonged periods of motorway driving under full load and driving across steep mountain passes with a trailer attached at high outside temperatures. The detailed simulation data enable the engineers to precisely calculate through-flow in the engine compartment and, therefore, the flow to all the components and assemblies.

Based on the data obtained, specific measures are implemented to combat any hot spots and to ensure effective cooling of all components under all operating conditions. The temperature experts can therefore propose additional or modified cooling air apertures, the relocation of certain components or the installation of heat dissipation panels, for example. All of these measures can then be verified by carrying out extensive field testing.

4MATIC permanent all-wheel drive and seven-speed automatic transmission

4MATIC – the permanent all-wheel-drive system from Mercedes-Benz – works together with the powerful engines and 7G-TRONIC seven-speed automatic transmission installed in the GL-Class to provide outstanding handling whatever the conditions. All-wheel drive is provided by a two-stage transfer case with reduction gearing, which is flange-mounted directly onto the 7G-TRONIC automatic transmission. Two propshafts with constant-velocity joints normally distribute the drive torque evenly between the front and rear axle, while a bevel-gear differential takes care of any differences in the rotation speed. In the event of different rotation speeds at the individual wheels, due to traction slip, the 4ETS traction system intervenes to vary the torque distribution. In this case, the torque is sent to the wheels offering the best traction by braking the spinning wheel(s).

The 7G-TRONIC seven-speed automatic transmission is operated using a control lever. Alternatively, shift buttons on the back of the steering wheel can be used to select the gears manually. Options available for making the driver's life easier include the DISTRONIC radar-based proximity control and cruise control system which detects vehicles ahead and maintains a set safety distance automatically.

Superlative on-road handling

One of the main aims when designing the chassis was to ensure that the excellent off-road pedigree of the GL-Class did not infringe upon its on-road performance in any way. The chassis engineers at the Mercedes Technology Center (MTC) successfully achieved this objective. Despite a kerb weight of around 2400 kg, the high payload, a wheelbase of 3075 mm and a vehicle length of 5088 mm, the handling agility and manoeuvrability are on a par with those of far more compact and lightweight cars.

The double-wishbone front suspension, including anti-dive control and a stabiliser bar, is connected to the body by means of a rubber-mounted subframe. Thanks to this vibrational decoupling and the high position of the upper control arm, the double-wishbone front suspension, or "high-link axle" ensures exceptionally low road noise and tyre vibration as well as outstanding handling. A subframe is also used to connect the body to the four-link rear axle which has a lower wishbone, an upper link level with a supporting strut and a leading/trailing link as well as a track rod at wheel centre. By virtue of its design, the directionally stable axle features both anti-squat control and anti-dive control. The agile and sure handling is also down to the speed-sensitive power steering. At higher speeds, there is less steering assistance for the driver, resulting in better road feel. At lower speeds, for example when manoeuvring or parking, the steering is extremely light.

AIRMATIC and the Adaptive Damping System as standard

One of the most impressive standard features of the new GL-Class is the multi-talented AIRMATIC air suspension which provides outstanding on-road comfort and substantially enhanced directional stability. AIRMATIC compensates for variations in the vehicle load and driving conditions and also functions as a level control system. Away from the road, the full air suspension system enhances the vehicle's off-road capability by providing additional ride heights.

The body can be raised or lowered at any time, either automatically or at the request of the driver, whilst the engine is running. The system is speed-sensitive, automatically lowering the body by 15 mm at both axles when the speedometer needle reaches 140 km/h, thus reducing aerodynamic drag and improving directional stability. Once the speed drops back below 40 km/h, the body is raised to the normal level again. An overview of the different levels:

In the standard specification, AIRMATIC works in tandem with the ADS Adaptive Damping System which adjusts the damping rates according to requirements, depending on the road conditions, driving style and vehicle load. Switchable sole-noid valves in the gas-filled dampers allow the compression and rebound stage to be adjusted for each wheel in line with the situation in hand. Depending on the control command, the valves can set one of four characteristics within an extremely short time (less than 0.05 seconds):

If the body speed exceeds a certain level, the system constantly switches between the second and third damping stage based on the skyhook algorithm, thus effectively compensating for the rolling and pitching motion of the body. The current driving situation is detected by means of a steering angle sensor, three acceleration sensors on the body, the speedo signal, the ESP® data and the brake pedal switch signal. Based on this information, the electronic control unit determines the best damping force in each case and selects the corresponding damper characteristics. In addition, the driver can influence the switching points and spring rates at the push of a button on the centre console, which enables "Auto", "Sport" or "Comfort" mode to be selected. At the front axle of the new GL Class, the adjustable ADS gas-pressure shock absorbers and the air springs are integrated in a spring strut. At the rear axle, the ADS shock absorber is located behind the air spring. In addition, torsion-bar stabilisers are fitted at the front and rear.

Powerful brakes

The new GL-Class features large, internally ventilated disc brakes with sliding callipers at both the front axle and the rear axle. Attributes of the brake system include excellent response, high resistance to fading and a long service life. The brake data at a glance:

Wide-base tyres and 18 to 20-inch light-alloy wheels emphasise the impressively confident appearance of the new GL-Class. Standard equipment for the six-cylinder GL 320 CDI model includes 5-spoke light-alloy wheels with 265/60 R 18 tyres. The eight-cylinder GL 420 CDI, GL 450 and GL 500 models come with 19 inch 5-twin-spoke light-alloy wheels and 275/55 R 19 tyres. Options available for all GL-Class variants include five-spoke 8.5 J x 20 wheels with 275/50 R 20 tyres.

When the going gets rough: the OFF-ROAD PRO engineering package

While the GL-Class cuts a fine figure on the road, its performance off the road is equally impressive. The modified AIRMATIC system permits a ground clearance of 307 mm in the highest off-road mode, in which case the fording depth is 600 mm. Should the ground clearance on occasion prove insufficient, a steel under-guard protects the important chassis and powertrain components. The off-road data at a glance:

The standard-fit OFF-ROAD PRO engineering package extends the range of options for negotiating normally impassable terrain considerably. Thanks to the transfer case reduction gearing (2.93 : 1) and multiple-disc locks with up to 100% locking at the reinforced rear axle and in the centre differential, almost all off-road terrain becomes passable. The traction-control measures are backed up by the 4ETS traction control system which increases the drive torque at the wheels offering good grip by braking the wheels providing less traction, thus enabling headway to be made even under the toughest of driving conditions. The front axle is also equipped with an "electronic" differential lock which, in contrast to mechanical locks, ensures that the vehicle remains fully steerable.

In addition to 4 ETS, there are further electronic dynamic handling control systems which help to make the driver's job easier when negotiating difficult terrain. These systems, which may be fitted as standard in certain countries, even if the OFF-ROAD PRO engineering package is not specified, include the following:

Two rotary controls on the centre console allow the driver to select from the drive modes and AIRMATIC modes, details of which are permanently visible on the central information display.

Design: A symbol of muscular power and prestige

The appearance of the new GL-Class leaves observers in no doubt whatsoever as to the strong character of the luxurious Sport Utility Vehicle: the premium off-roader from Mercedes-Benz displays size, robustness and muscular power in abundance as well as being sporty and dynamic in character. Despite a typically off-road body with short overhangs, its own, vibrant personality shines through.

This effect is thanks in no small part to an extremely linear design that is without superfluous flourishes yet displays remarkable finesse. Large surfaces and clearly defined, powerful lines create distinctive contours and visually emphasise the robustness and sheer athleticism at the heart of the GL-Class. The roof rails, wheels and exterior mirrors are generously proportioned and enhance the powerful appearance. At the same time, a closer inspection reveals finely drawn, sinewy lines that add to the extraordinary appeal of the new Mercedes off-roader, giving it a highly prestigious feel. This is a luxury vehicle with backbone and noblesse.

Front end with a no-nonsense character

The front-end design also emphasises the solid nature of the new GL-Glass. A steeply angled, robust radiator grille with a centrally positioned star dominates the front view. Two particularly powerful transverse louvres in silver with broad chrome highlights lend the vehicle a muscular look. The backdrop here is provided by a black honeycomb structure which is echoed in the air intake opening below the bumper.

The high bonnet, a classic off-road feature, has two powerdomes running along its length. Sharply defined ridges delineate the bonnet on the left and right and form an unusually distinctive link between the bonnet and headlamps, evoking the image of an athletic, chiselled musculature.

The wide clear-lens headlamps together with the clearly structured halogen projection-beam technology form a high-quality light unit. The fog lamps (with the cornering light function if this option is ordered) are housed in the bumper in a separate, extremely solid frame whose robust design is emphasised by two horizontal fins. The standard-version light units are ringed in black. If the cornering light function is specified, they have chrome surrounds.

The upper part of the bumper is painted in body colour, while the section below this is trimmed in dark grey. This horizontal colour contrast makes the off-roader appear lighter and sleeker. A chrome-look underride guard, available as an optional extra, reinforces this impression.

Silhouette: elegance and durability

From the side, it is clear that the GL-Class offers ample space. There is an overriding impression of length. The long wheelbase and a high roof line which extends as far as the rear wall create a dynamic silhouette. Large window areas emphasise these lines, further adding to the air of elegance whilst also ensuring excellent visibility and a bright interior atmosphere. By way of contrast, the upright D-pillar is in keeping with the off-road character and solidity of the vehicle and serves to underline its dependability in any situation.

Dynamic side lines, which make the vehicle appear longer whilst also emphasising its strong, solid character, are testament to a meticulously thought-out design. A crease line emerges from the headlamp surround and runs smoothly along the front wing, across the A-pillar and the side roof frame before reaching the tailgate. Most prominent of all is the waistline which emanates ahead of the front wheel arch, rises rearwards and reaches its conclusion at a point above the tail lights. Beneath this is a further crease line stretching from the front wing, across the doors and as far as the D-pillar.

Generously-sized rub strips add structure to the side surfaces and, together with the solid roof rails in black or chrome, create a sporty, prestigious appearance.

The powerfully accentuated wings with broad chamfered edges and the large light-alloy wheels with robustly dimensioned spokes lend the vehicle a firm-looking stance.

Distinctive rear end

The high rear end is divided by horizontal crease lines which emphasise the width of the vehicle and reduce the impression of height. This effect is reinforced by the raised position of the sturdy rear bumper, the high-quality chrome handle in the tailgate and the chromed rectangular tailpipes occupying a wide position on each side of the rear end.

The impressive tail lights feature a new take on the classic Mercedes-Benz "ribbed lenses" theme. Ribbed areas and smooth surfaces alternate whilst two wide highlights, which are themselves subdivided by chrome highlights, appear to split the tail lights.

The reflectors have been removed from the main light unit and are now arranged separately in the bumper below the loading sill. The third brake light has been located in the roof spoiler.

Optional extras include a stainless-steel scratch guard on the bumper loading sill as well as a chrome-look stainless-steel underride guard similar to the one fitted at the front end.

High-grade interior materials

The interior is dominated by high-quality materials displaying handcrafted precision and attention to detail, creating a luxurious, tasteful ambience which embraces the special character of an off-roader in many respects. The smooth dashboard and door surfaces underline robustness and self-assurance, whilst the colour contrast between the darker upper section and the lighter lower section as well as the continuous wood trim elements lend the interior a sense of breadth and spaciousness.

Drivers of the new GL-Class sit behind a four-spoke multifunction steering wheel featuring aluminium-style lower spokes. Behind this is the upper section of the dashboard, also trimmed in leather, rising in a powerful arch that spans the instrument clusters. The instruments are housed in two slanting tubes, making them easy to read and giving them a sporty appearance. Fine chrome rings surrounding the tubes add a further touch of elegance.

The console in the centre of the dashboard features a clearly defined, smooth design and houses easy-to-reach, logically positioned control and display functions. Here the emphasis is firmly on perfect ergonomics and tangible precision. Adjoining this area is the sturdy centre console with stowage compartments and integral cup holder functions as well as two robust, longitudinally arranged grab handles which echo the lines of the trim strips in the doors and provide useful support points when driving off-road.

The door centre panels and the armrests are padded and feature an elegant trim as well as distinctive topstitching. Once again, wood trim elements catch the eye. There is a choice between bird's-eye poplar, burr walnut with chrome trim strips or pale birch with chrome trim strips.

Colours and paints

The new GL-Class comes with a choice of three interior appointments colours: black, alpaca grey or buckskin (a fine shade of beige). These can be combined with two non-metallic and nine metallic paint finishes.
