Expressive, powerful and elegant: the exterior design
The design idiom of the exterior is the embodiment of hallmark AMG Driving Performance. Membership of the Affalterbach model family is obvious at first glance thanks to the AMG-specific radiator grille in high-gloss chrome. The stylish and striking coupé silhouette makes for a self-assured appearance, with design lines that clearly convey the passion for performance. 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 coupé design all round.
The side skirts, exterior mirror housings and flared wheel arches are painted in the vehicle colour, and seamlessly blend into the muscular overall look. The base model is shod with 21-inch light-alloy wheels with AMG lettering as standard, while the S variant comes with 22-inch wheels ex factory. Other wheel variants with diameters from 21 to 22 inches are optionally available.
The newly designed rear apron with AMG-specific details such as a striking diffuser in black and a trim strip in silver chrome visually accentuate the vehicle’s width. The special AMG exhaust system with two rectangular high-gloss chrome-plated twin tailpipe trim elements completes the sportily dominant look – the tailpipe trim elements on the S variant are visually differentiated by a characteristic fluted effect. 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. In addition, the twin tailpipe trim elements are finished in elegant high-gloss black.
Progressive, elegant and aesthetic: the interior design
The typical look and feel of the brand is continued in the high-quality interior of the GLE 63 Coupé, which is characterised by a resolutely sporty ambience with a dynamic and exclusive flair. The 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. Other leather variants are optionally available. The S variant is further identified by its grey seat belts and contrasting topstitching in the seats in silver grey. Individually adjustable ambient lighting comes as standard.
AMG-specific interior appointments and controls lend the cockpit a hallmark AMG atmosphere and support agile, precise handling. The three-spoke AMG Performance steering wheel with aluminium shift paddles impresses with its optimum driver-oriented ergonomic design. In the base model the steering wheel rim is lined in black nappa leather, and in the S variant in nappa leather/DINAMICA microfibre, in each case with a black 12-o’clock marking. As a further option, there are the AMG steering wheel buttons for particularly fast setting of dynamically relevant parameters.
The centre console includes an AMG-specific control unit with additional switches that are used to regulate the 3-stage ESP®, the manual transmission mode, the Adaptive Damping System, the optional AMG Performance exhaust system and the vehicle level. Alongside the AMG brushed stainless steel sports pedals with rubber studs, door sill panels and black floor mats with “AMG” lettering accentuate the sporty look. A wide range of high-quality interior trim elements is available for further individualisation of the interior. AMG trim elements in carbon fibre lend a particularly sporty touch to the interior.
Continuation of electrification: the EQ Boost starter-alternator in the AMG 4.0-litre V8 biturbo engine
The 4.0-litre V8 biturbo engine in the new GLE 63 Coupé is fitted in both output variants (420 kW/571 hp and 450 kW/612 hp) with an integrated EQ Boost starter-alternator. It combines a starter motor and an alternator in a single, powerful electric motor compactly integrated between the engine and the transmission. The additional 16 kW (22 hp) of output plus 250 Nm of torque which can be called upon temporarily not only enable more spontaneous moving-off characteristics. This is because moreover, this innovative component supplies the 48-volt on-board electrical system, is used as a power generator and also performs hybrid functions. These include boost, recuperate, load point shiftand the virtually imperceptible restarting of the engine with the start/stop function.
The AMG 4.0-litre V8 engine works with the well-proven twin turbocharging, where the two exhaust-gas turbochargers are arranged not on the exterior, but between the cylinder banks. The advantages of the “hot inside V” are the compact engine design and the immediate response of the exhaust-gas turbochargers. These are implemented using twin-scroll technology to make optimum use of the exhaust gas flow and improve the response even further.
Precise and fast: the AMG SPEEDSHIFT TCT 9G transmission
The SPEEDSHIFT TCT 9G transmission is specially tuned to the requirements of the eight-cylinder engine in the GLE 63 Coupé. The systematic further development of hardware and software has made it possible to further optimise the reaction times. This means that automatic and manual shift commands can be implemented more quickly than ever before. Various reinforcement measures also ensure durability and performance with the high torque generated by the V8 engine.
The extensively tailored software enables extremely short shift times and fast multiple downshifts and delivers an especially emotive gearshifting experience thanks to the double-declutching function. Gear changes are performed with no interruption in tractive power. Dynamic acceleration and very short shift times are just as available as a fuel-efficient driving style depending on the selected mode.
Highlights of the transmission:
- adaptation of the shift characteristics to the selected AMG DYNAMIC SELECT drive program
- in manual mode “M” the transmission responds directly to manual shift commands by the driver – the powertrain responds precisely and executes the commands almost instantly
- the temporary M mode allows an immediate change to manual mode “M” – merely by using the shift paddles
- automatic double-declutching function when downshifting: this effect is automatically active in the drive programs “Sport”, “Sport+” and “RACE” (exclusive to the S variant)
- the ECO start/stop function is automatically active in the “Comfort” drive program
- the “gliding” function can be individually activated in “Individual” mode
The intelligent AMG Cylinder Management system
For increased efficiency, Mercedes-AMG has also equipped the V8 engines with cylinder deactivation. 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 more powerful 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.
With AMG-specific displays: the MBUX infotainment system
The innovative MBUX control and display concept is a standard feature of the GLE 63 Coupé, creating 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.
The “Supersport” view provides extensive additional information specific to AMG, such as a prompt borrowed from motorsport to shift up in manual transmission mode, a feature known as “Shiftlight”. Via the AMG menu, the driver can call up various special displays:
- Gear display with yellow “M” symbol in manual mode
- Warm-Up menu engine and transmission oil temperature
- Set-Up menu AMG DYNAMIC SELECT settings
- G-Meter – longitudinal and lateral acceleration forces
- RACETIMER – stopwatch, lap and sector times
- Engine data – output and torque, engine oil and transmission oil temperature
Standing firm: the AMG high-performance brake systems
In line with the high output values and their associated performance, the new GLE 63 Coupé models have a large-dimensioned high-performance brake system with 6-piston fixed brake callipers and 400 x 38 mm brake discs at the front, plus single-piston floating brake callipers and 370 x 32 mm discs at the rear. The S variant is characterised by red brake callipers, while the base variant has grey brake callipers.
As an option a high-performance ceramic brake system with bronze-coloured 6-piston fixed callipers at the front and single-piston floating brake callipers at the rear can be ordered, saving weight compared with the compound discs and thus reducing the unsprung masses. Further advantages are their high overall and fading stability under high stress. The brake system also scores highly with a long operating life and particularly fast responses.
Even sportier: the air suspension with continuous damping adjustment
The standard AMG RIDE CONTROL+ air suspension and the adaptive damping adjustment 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+ Coupé maintains a constant ride height irrespective of the vehicle load. This can be adjusted depending on the driving mode, or manually using a rocker switch in the centre console. In the AMG DYNAMIC SELECT drive programs “Sport”, “Sport+” and “RACE” (S variant only), the vehicle level is lowered. In the “Comfort” program, the vehicle is lowered at speeds of 120 km/h or above, 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 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.
