The new Mercedes-AMG GLE 63 4MATIC+ and GLE 63 S 4MATIC+: More powerful, efficient and suitable for day-to-day use than ever before

With the new Performance models based on the GLE, Mercedes-AMG is continuing a precisely 20 year-old tradition: in 1999 the ML 55 was the top model in M-Class range with its 347 hp V8 engine. The same applies to its current successor in the guise of the Mercedes-AMG GLE 63 4MATIC+. The top-of-the-line performer of the model series is naturally taking to the starting line with state-of-the-art engine technology: the AMG 4.0-litre V8 biturbo engine generating 571 hp in the GLE model series and 612 hp in the S version is combined for the first time with the EQ Boost starter-alternator.

This is accompanied by an additional electric output of 22 hp, a 48-volt on-board electrical system, cylinder shut-off and petrol particulate filter for optimum efficiency. Furthermore, the fully variable all-wheel drive, the air suspension with adaptive damping adjustment and active roll stabilisation and the extremely fast-shifting TCT 9G transmission further move the limits of vehicle dynamics upwards.

On top of this there are the advantages of a luxury SUV: good all-round visibility, plenty of space for passengers and luggage, high-quality materials and the brand’s very latest driving assistance, infotainment and connectivity functions. Even more versatility is provided by the improved off-road capabilities with the two additional drive programs “Trail” and “Sand”, as well as the variable vehicle level. This is where extreme sportiness, first-class off-road characteristics and absolute day-to-day suitability come together.

“With our new GLE Performance models we are transforming a 20-year tradition into the future. For the first time we are electrifying our well-proven 4.0-litre V8 biturbo engine with an EQ Boost starter-alternator and a 48-volt on-board electrical system. As such we are embarking on another new chapter of our drive technology, which we are also successively extending further to other model series as we move towards electrification and hybridisation. With our new premium SUVs, our customers can look forward to an unrivalled package of Driving Performance, high day-to-day suitability, optimum traction on practically all surfaces and also comfort on long journeys with high levels of efficiency,” says Tobias Moers, Chairman of the Board of Management of Mercedes-AMG.

Improved efficiency: the intelligent AMG Cylinder Management

For increased efficiency, Mercedes-AMG has also equipped the V8 engines with cylinder shut-off. In the partial-load range, cylinders two, three, five and eight are deactivated, which crucially reduces the fuel consumption. When the driver has selected the “Comfort” drive program, the cylinder deactivation system is available in the wide engine speed range from 1000 to 3250 rpm. A special display in the instrument cluster indicates whether the cylinder deactivation system is in use and whether the engine is presently operating in four or eight-cylinder mode. The transition between these two operating states is immediate, fast and torque-neutral, so the passengers do not have to relinquish any comfort.

In the most powerful AMG GT S variant, the eight-cylinder has active engine mounts. They resolve the conflicting aims of achieving as soft a connection as possible to the powertrain for high comfort, and as rigid a connection as possible for optimum driving dynamics, by steplessly and quickly adapting their rigidity to the respective driving conditions.

For heightened sportiness: air suspension with continuously adjustable damping

The standard AMG RIDE CONTROL+ air suspension and the adaptively adjustable ADS+ (Adaptive Damping System) configured for the characteristics of an SUV combine outstanding agility and excellent vehicle dynamics with maximum traction and superb day-to-day comfort. The damping characteristics can be preselected in three stages – “Comfort”, “Sport” and “Sport+”, allowing a much more obvious distinction between high long-distance comfort and sporty vehicle dynamics.

Thanks to pneumatic self-levelling, the new GLE 63 4MATIC+ maintains a constant ride height regardless of the vehicle load. This can be adjusted depending on the driving mode, or manually using a rocker switch in the centre console. The vehicle level is generally lowered by 10 mm in the AMG DYNAMIC SELECT drive programs “Sport”, “Sport+” and “RACE” (S variant only). In the “Comfort” driving mode, the vehicle is lowered by 10 mm from a speed of 120 km/h, and raised back to normal level when the speed falls below 70 km/h. This reduces aerodynamic drag and therefore fuel consumption. In addition, handling stability is improved thanks to a lower centre of gravity.

In the drive programs “Trail” and “Sand”, the suspension is raised by 55 mm to increase ground clearance on poor surfaces, and automatically lowered to normal level when the speed reaches 70 km/h. This function can also be controlled using the rocker switch.

More traction and dynamism: the locking differential

The design idiom of the exterior embodies sheer energy and Performance Luxury. The AMG-specific radiator grille with vertical louvres reaffirms membership of the AMG model family, while the dynamic arrow-shape of the front section with its smaller angle of approach emphasises the distinctive proportions. As a typical feature of the Performance models, the front apron in a dynamic jet-wing design is painted in the vehicle colour and has black air intakes. Imposing powerdomes in the bonnet and the front splitter in silver chrome emphasise the sharper all-round design.

The newly designed rear apron with AMG-specific details such as a striking diffuser and a trim strip in silver shadow visually accentuate the vehicle’s width. The special AMG exhaust system with two rectangular twin tailpipe trim elements (with characteristic corrugation for the GLE 63 S) and the roof edge spoiler round off the sporty look.

Further individualisation options are available in the AMG Night package. This includes heat-insulating, dark-tinted windows and also the front splitter, front and rear apron trim, inserts in the side skirts, mirror caps and window frames in dignified black. Plus the twin tailpipe trim elements are finished in black chrome.

Exterior design – muscular and distinctive

The EQ Boost starter generator is a key component of the 48 V system and not only serves as an alternator, but is also responsible for hybrid functions. This allows fuel savings that were previously reserved for high-voltage hybrid technology. For the first time, the EQ Boost starter-alternator is also responsible for idle speed control.

The hybrid functions include boost with 16 kW of output and 250 Nm of torque, energy recovery, shifting of the load point, gliding mode and the virtually imperceptible restarting of the engine with the start/stop function.

Because the belt drive for ancillary components on the front edge of the engine is omitted, the installation length of the new six-cylinder engine is also significantly reduced compared with conventional six-cylinder engines. This creates space for an exhaust gas aftertreatment system mounted near the engine, which is therefore particularly efficient. The particulate filter is the only part of the emission control system that is under the floor.

A special acoustic experience comes courtesy of the optional, selectable AMG Performance exhaust system. The variable adjustable exhaust flaps give the option to change the sound of the vehicle at the press of a button. Depending on the drive program, the sound characteristics change from unobtrusive comfort through to maximum emotive appeal.

Interior design – progressive elegance and robust ambience

The high-quality interior is characterised by a systematically sporty ambience with a dynamic and exclusive touch. The standard AMG seats are upholstered in nappa leather, provide optimum lateral support and have an AMG-specific seat pattern layout with an “AMG” badge in the front backrests.

The centre console has an AMG-specific control panel with additional switches with which the 3-stage ESP®, manual transmission mode, the adaptive damping adjustment, the optional AMG Performance exhaust system and the suspension level can be controlled.

With AMG-specific displays: the MBUX infotainment system

The innovative MBUX control and display concept in the new Performance SUVs creates an even closer bond between the vehicle, driver and passengers. At the same time, the latest version of the infotainment system contributes to the great day-to-day practicality. Emotive displays such as the particularly striking Supersport mode with a central rev counter and 3D-look scales lend visual depth to the instrument and accentuate the exclusivity.

Whether it’s operated with the touchpad, Touch Control buttons on the steering wheel, by voice control or gesture control: the control concept is both versatile and flexible. Thanks to the innovative voice control – activated with the keyword “Hey Mercedes” – the AI software recognises and understands practically all commands common in infotainment and vehicle control – even when spoken indirectly.

With the four AMG-specific display styles “Modern Classic”, “Sporty”, “Discreet” or “Supersport”, the vehicle functions are directly visualised on the instrument cluster on the left side and on the touchscreen display on the right. Visually, the two displays under one shared glass cover blend into a Widescreen Cockpit and as a central element consequently emphasise the horizontal orientation of the interior design.
