The 3^rd Generation GLS SUV (2020-25)

Exterior design: powerful presence

Modern luxury both on and off the road: that is the design message of the new GLS. Its aesthetics are based on the confident presence that its impressive dimensions alone create (length 205.2 in, width 77 in). The wheelbase of 123.4 inches, which is 2.4 inches longer than that of its predecessor, makes the vehicle beneficially longer and gives it harmonious proportions, emphasized by the understated, elegant side design. The GLS follows the design strategy of Sensual Purity, and dispenses with individual edges and beading in favor of generously sculptured surfaces.

The front section of the new GLS exudes a powerful presence: this is ensured by the upright radiator grille in an octagonal SUV interpretation, the prominent, chrome-plated under guard in the front bumper with the bone- shaped air inlet grille, and the hood with two power domes. This striking appearance is emphasized day and night by the distinctive headlamp design. The GLS is equipped with MULTIBEAM LED headlamps as standard, with a total of 112 LEDs per headlamp. These produce the maximum light intensity permitted by law, which results in the brightness of the main beam headlamps only falling below the reference value of 1 lux after a distance of more than 2,000 feet (650 meters). The daytime running lights with three LED segments underline the status of the GLS as the S-Class of SUVs.

The GLS cuts an imposing figure from the rear, too. This is particularly ensured by the powerful shoulder muscle extending from the rear doors to the tail lamps, which enables the GLS to strike an imperious pose on the road. The two- piece tail lamps are based on LED technology, and their high-caliber, three- dimensional look conveys depth and solidity. The reflectors are relocated lower down, giving the tail lamps a flatter appearance. They are crowned by a slender, continuous chrome trim strip. The rear is strikingly rounded off with the chrome-plated under guard.

Aerodynamics: exquisite fine-tuning

The new GLS achieves global cd figures as low as 0.32 - a clear improvement compared with its predecessor (cd 0.35) and an impressively low figure in the large luxury SUV segment. The excellent aerodynamics help to reduce fuel consumption and limit wind noise, one of the areas on which development work focused specifically.

Special attention was paid to the underbody and the air flowing through the engine compartment because the hallmark SUV shape, with its upright front end and high ground clearance, makes these areas susceptible to low- frequency airflow noise. A host of details were optimized with numerous computation loops, CAE simulations (computer-aided engineering) and measurements in the wind tunnel in Sindelfingen.

Interior design: luxuriously elegant and powerfully progressive

The interior of the new GLS is all about luxuriously elegant aesthetics, as evidenced immediately by the interior appointments that combine the comfort of a Mercedes-Benz luxury sedan with the robustly progressive detailing of an SUV. The central element in the dashboard's design is an impressively sized screen unit embedded in a distinctive dashboard support. The dashboard support flows into the door panels, and the integral trim element extends to meet the doors.

The prominently wide, raised center console creates a robust contrast with the free-floating appearance of the dashboard. As a typical feature of off-roaders, there are two prominent grab handles on the center console. Apart from good ergonomics, fluent surfaces create a modern, luxurious impression, rounded off by a broad area of trim and flush-fitting sun blinds. The controls with haptic and audible feedback appear to have been milled from a solid metal block.

The large touchscreen of the MBUX infotainment system allows all the GLS comfort features to be controlled from the driver's seat. Very fine chiseling and the pyramid structures of the trim surfaces showcase the desire for perfection and craftsmanship. The new multifunction sport steering wheel with its striking spoke design accentuates the impressive appearance of the SUV's interior.

Interior: generous amount of space in the second and third seat row

The new GLS has a considerably longer wheelbase than its predecessor (123.4 in, an increase of 2.4 in). This creates more space, especially in the second seat row, which can also be adjusted. Legroom here is increased by 3.4 inches when the seats are in their rearmost position, which also makes it easier to get into the vehicle.

As standard, the second row has a 60:40-split folding rear bench seat with adjustable 40:20:40-split backrests. Alternatively, it is possible to order the two luxury individual rear seats with armrests, between which it is possible to access the rearmost seats with ease. This is particularly useful when child seats are fitted in the second seat row.

All seats are electronically adjustable. The same applies to the EASY-ENTRY function, which makes it easy to get into and out of the two individual seats in the third row. For this, the seats in the second row move a long way forwards and fold forwards.

The seats in the third row are fully-fledged seats that are suitable for people up to 6.4 feet (1.94 m) tall and are heated for the first time. There are also two additional USB charging ports here.

The new GLS has several climate control options: three-zone, four-zone or five- zone. If the GLS is equipped with the five-zone automatic climate control (as is standard with the GLS 580), the third row has its own zone with climate control vents in the roof. This zone is supplied by its own, electrically powered heater and air conditioner.

A push of a button is all that is required to stow away the comfortable seats and make full use of the trunk space in the GLS. The switches on the left and right of the load compartment and on the front of the wheel arches on the front- passenger side in the C-pillar area allow the seats in the rear rows to be folded completely flat. It is also possible to fold down all the seats simultaneously by pressing the "ALL" button. The carpet-trimmed backs of the backrests form part of a flat, practical load area. Another push of a button lowers the trunk sill by approximately 2 inches to make it easier to load heavy or bulky items.

Even more comfort in the rear: MBUX served on a tablet

Luxury in the new GLS is shared generously among all passengers, particularly if the Executive Rear Seat Package is ordered. It includes a 7-inch Android tablet in its own docking station in the second row's larger luxury center armrest. The tablet allows control of all MBUX comfort and entertainment functions (see next section) from the rear seat rows, such as access to the radio, media, phone and a web browser. It can also be used to control the Executive Rear Seat Package and the five-zone automatic climate control for the rear seats. The driver can seamlessly assume control of all options and features from his or her seat at any time too.

The center console also offers a wireless charging compartment for smartphones and additional USB ports. Rear passengers are indulged further still thanks to luxury headrests with additional cushions and the rearward- extended center console between the front seats with cup holders.

It is even possible to order rear seats with a lumbar massage function and climate control as an additional option for the Executive Rear Seat Package Plus in the second row.

MBUX with Interior Assistant

The GLS is equipped with the latest generation of the infotainment system MBUX (Mercedes-Benz User Experience). Upgrades compared with the A-Class, in which the revolutionary system made its debut, include two large 12.3-inch screens as standard. The information on the digital instrument cluster and central media display is easily legible on the large, high-resolution screens. The presentation with brilliant graphics underlines the comprehensibility of the intuitive control structure.

The optional MBUX Interior Assistant also allows intuitive operation of different comfort and MBUX functions by movement recognition. A camera in the overhead console registers movements of the driver's and front passenger's hands and arms. When a hand approaches the touchscreen or the touchpad on the center console, the media display changes and individual elements are highlighted. The system is able to distinguish the driver's hand from that of the front passenger, and therefore knows for whose seat the massage function is to be activated, for example.

In addition there are functions that can be controlled by simple hand gestures: the reading lamp can be switched on and off by extending a hand towards the interior mirror, for example. Furthermore, the driver and front passenger can each store personal favorite functions such as "navigate home" or "call office."

A unique feature of MBUX (Mercedes-Benz User Experience) is its learning capability thanks to artificial intelligence. With its predictive functions, MBUX anticipates what the user would like next. For instance, anyone who often calls their mother on Tuesdays during their drive home will receive her telephone number as a suggestion in the display on this day of the week. Anyone who regularly switches over to a radio station with news at a certain time also receives this as a suggestion.

Also available is a next-generation full-color Head-up Display, which sets new standards with a resolution of 720 x 240 pixels and an extended projection distance.

Powertrain: all engines have an EQ Boost integrated starter generator

The high aspirations of the new Mercedes-Benz GLS are also clearly apparent in its engine line-up. Powerful six and eight-cylinder engines deliver the comfort and effortlessly superior power that suit the characteristics of this luxurious vehicle.

The introduction of the GLS 580 4MATIC will mark the world premiere of a new, electrified V8 gasoline engine with 48-volt on-board electrical system and integrated starter generator. It has an output of 483 hp and 516 lb-ft of torque, with a further 184 lb-ft of torque and 21 hp available via EQ Boost over short periods. The integrated starter generator (ISG) is responsible for hybrid functions such as EQ Boost or energy recuperation, while allowing fuel savings that were previously reserved for high-voltage hybrid technology.

ISG eliminates the need for a belt drive for ancillary components at the front of the engine, which reduces its overall length. The slim design of the in-line engine, together with the physical separation of intake/exhaust, creates space for close-coupled exhaust after treatment. The 48 V on-board electrical system serves not only high power consumers, such as the water pump and air- conditioning compressor, but also the integrated starter-generator (ISG), which also supplies energy to the battery by means of highly efficient energy recuperation.

The Mercedes-Benz GLS 450 4MATIC is also available with a six-cylinder in- line engine electrified with 48-volt technology. This sophisticated engine produces 362 hp and 369 lb-ft of torque, with a further 184 lb-ft of torque and 21 hp available via EQ Boost over short periods.

4MATIC variable all-wheel drive: agile on the road, superior when off- road

In all variants of the new GLS, power is transmitted by the 9G-TRONIC automatic transmission. The broad ratio spread of gears from one to nine allows a clearly perceptible reduction in engine speed and is a decisive factor behind the high level of energy efficiency and ride comfort. A transfer case with an electronically controlled multi-plate clutch is also fitted as standard. This allows a variable transfer of drive torque from 0-100 percent (torque on demand) between the axles.

Also new, and available as an option on the GLS 580, is a transfer case specially configured for superior off-road driving characteristics. In addition to the controlled multi-plate clutch with torque-on-demand function, it also features a reduction gear for off-road driving.

When driving on the road, and particularly when cornering, the two fully networked transfer cases with torque-on-demand function allow a further improvement in handling safety and agility by specifically influencing the degree of yaw to induce oversteer or understeer.

Driver assistance systems: even better support

The new GLS is equipped with the latest generation of Mercedes-Benz driver assistance systems giving cooperative support to the driver. These systems further enhance the level of active safety.

When Active Distance Assist DISTRONIC with route-based speed adaptation is activated, the new GLS is able to recognize and respond to traffic jams or slow-moving traffic with the help of information from LiveTraffic before the driver becomes aware of the hazard. For example, when a traffic jam is detected on the highway (and if the driver does not choose a different response), DISTRONIC reduces the speed to around 62 mph (100 km/h) as a precaution.

A new feature of the Driver Assistance package: when actually driving in a traffic, Active Stop-and-Go Assist is substantially able to perform the tasks of keeping the vehicle in the lane and maintaining a safe distance with a high level of availability at speeds up to around 37 mph (60 km/h). In addition, restarting can be automatic up to one minute after coming to a stop. Once the traffic jam clears, the GLS accelerates back up to the speed preset for Active Distance Assist DISTRONIC with route-based speed adaptation. If traffic signs differ from this, the sign posted speed limit is automatically given priority.

Suspension: AIRMATIC air suspension as standard

The GLS comes with the enhanced AIRMATIC air suspension system with Adaptive Damping System Plus fitted as standard. This setup uses highly complex sensor systems and algorithms to adapt the damping characteristics to the road condition and driving situation in real time. All components have been enhanced compared with the previous generation, and the wheel suspension mountings have been optimized to maximize ride comfort. In addition, the air suspension keeps the car at the same level, regardless of the load on board.

Carwash function: ready for cleaning

One new standard feature is the Carwash function - which comes in handy, especially for a large vehicle like the GLS. When this function is selected, the suspension moves to the highest position, which reduces the track widths due to the axle geometry. This makes it easier to drive into a carwash as well as remove any dirt remaining in the wheel arches from the last off-road trip. The Carwash function also:

• Folds in the exterior mirrors.
• Closes the side windows and the sliding sunroof.
• Suppresses the rain sensor information so that the windshield wipers remain switched off in the carwash.
• Switches the climate control to air-recirculation mode and, after eight seconds, activates the 360° camera's front image to assist the driver when driving into the carwash
• Deactivates these settings automatically when the driver drives out of the carwash and accelerates to a speed above 12 mph.

Outstandingly intelligent suspension: E-ACTIVE BODY CONTROL

Even better ride comfort and agility plus new functions such as recovery mode are provided by the optional E-ACTIVE BODY CONTROL suspension, which is combined with the newly developed AIRMATIC air suspension. This is currently the only system on the market that can individually control spring and damping forces at each wheel. This means that it not only counteracts body roll, but also pitching and squat. Together with ROAD SURFACE SCAN and the curve inclination function CURVE, E-ACTIVE BODY CONTROL makes an exceptional level of comfort possible, and supports the claim of Mercedes- Benz to build the world's most intelligent SUV suspension.

E-ACTIVE BODY CONTROL operates with a voltage of 48 V. On poor road surfaces the system is even able to recuperate energy, roughly halving the energy requirement compared with the preceding system in the S-Class. The hydropneumatics generate dynamic forces that overlay the air suspension forces and actively support and dampen the vehicle body during linear and lateral acceleration or when driving on uneven roads.

The off-road functions include rocking mode. For example, if the GLS has become bogged down in a sand dune, this can help to free the vehicle more easily in many such situations. If possible, the suspension level is automatically raised and lowered several times, which changes the ground pressure of the tires and therefore improves traction and allows the GLS to rock itself free. Individual wheel actuation is another function for off-road driving. This allows the level at each wheel to be individually adjusted via the touchscreen of the media display, thus improving the vehicle's alignment on rough terrain when one wheel is stuck in a ditch or a wheel spring is fully contracted. This also helps to increase traction and the torque at the wheel.

E-ACTIVE BODY CONTROL in the GLS also has the curve inclination function CURVE: like a motorcycle, the GLS leans into bends and thereby allows cornering in three stages with practically no centrifugal force. If the GLS is equipped with a stereo multi-purpose camera, ROAD SURFACE SCAN becomes possible: the camera continuously scans the road surface, while the suspension responds in advance to any undulations before the vehicle drives over them and largely compensates for them. In this way, the GLS improves the perceived road quality.
