With the new Mercedes-AMG G 63, the Mercedes-AMG G-Class has undergone the greatest change in its history – while remaining true to its well-proven virtues.
The G 63 underpins its unique position among performance off-road vehicles with the powerful drive system, the newly developed AMG RIDE CONTROL suspension, the AMG-specific transmission modes and the new interior with optimal widescreen cockpit. The basis for the hallmark AMG Driving Performance both on and off metalled roads is provided by the 430 kW (585 hp) 4.0-litre V8 biturbo engine, the rear-biased all-wheel drive (40:60) with three differential locks, the extremely fast-shifting 9-speed automatic transmission, the double wishbone independent front suspension and the adaptive adjustable damping. The reinterpretation of the unmistakable design creates strong highlights with the AMG-specific radiator grille, flared wheel arches, striking side pipes on the exhaust system and the up to 22-inch wheels. Proven to be powerful: the AMG 4.0-litre V8 biturbo engine.
The AMG 4.0-litre V8 biturbo engine now also replaces the previous 5.5-litre V8 biturbo engine in the G 63. It generates 430 kW (585 hp) in this model, and delivers a maximum torque of 850 Nm. This is available across a wide rev range between 2.500 and 3.500 rpm, and provides a sense of effortless superiority. It absolves a sprint from zero to 100 km/h in 4.5 seconds. This dynamic performance is maintained up to the limited maximum speed of 220 km/h, or 240 km/h with the AMG Driver‘s package.
The two turbochargers are not positioned on the outside of the cylinder banks, but inside the cylinder "V". Advantages: a compact engine design, spontaneous response of the turbochargers and low exhaust emissions thanks to optimal airflow to the near-engine catalysts. The eight-cylinder delivers its power with muscular torque in all engine speed ranges, combined with maximum efficiency for low fuel consumption and emission figures.
Two twin scroll turbochargers are used for optimal response. The housing is divided into two parallel flow channels. Combined with two separate exhaust ducts in the exhaust manifold, this makes it possible to control the exhaust gases on the turbine wheel separately. The exhaust gas from the first and fourth cylinders of the cylinder bank is fed into one duct, that from the second and third cylinders to the other duct. The aim is to prevent the individual cylinders from having mutually adverse effects on the gas cycle. This reduces the exhaust gas back pressure and improves gas exchange. The results are increased output by virtue of improved cylinder charging with fresh mixture, more torque at low revs and very fast response times.
Other engine features include modified pistons, optimised intercooling and extensive software upgrades. Spray-guided direct petrol injection with piezo injectors, the all-aluminium crankcase, the four-valve per cylinder design with camshaft adjustment, air-water intercooling, alternator management, the ECO start/stop function and the gliding mode have all been retained.
AMG SPEEDSHIFT TCT 9G transmission with shorter shift times
The AMG SPEEDSHIFT TCT 9G transmission is used in the G 63. This has a model-specific software application to achieve very short shift times. The multiple downshift function allows more spontaneous bursts of speed, while the double-declutching function in "Sport" and "Sport Plus" transmission modes makes for an even more emotional driving experience. Defined engine manipulation makes for even faster gear changes.
The wide ratio spread allows a choice of a very sporty or a very comfortable and efficient driving experience. In all transmission modes the G 63 moves off in first gear so as to ensure a dynamic sprint from a standstill whenever required. The DIRECT SELECT lever has been repositioned as a steering column stalk.
"Manual" mode can be selected using a separate switch. The gear changes are based on the selected transmission mode, and the driver can now change gear using the paddles on the steering wheel. Moreover, the transmission stays in the selected gear and does not automatically shift up when the engine speed reaches the limit.
Enhanced agility and traction: AMG Performance 4MATIC all-wheel drive
The standard-specification AMG Performance 4MATIC all-wheel drive features rear-biased torque distribution with a front/rear split of 40 to 60 percent. This configuration ensures greater agility on the road and improved traction during acceleration. In the preceding model the distribution was still a neutral 50:50.
The off-road reduction gear has been developed further for operations on difficult terrain. It helps to ensure that the G 63 is able to master even more demanding off-road stretches. The reduction ratio of the transfer case is now 2.93, i.e. considerably higher than in the preceding model (2.1). This assists moving off on extreme uphill gradients in particular, as the torque at the drive wheels is significantly increased.
The off-road reduction gear can be engaged via the LOW RANGE switch at speeds of up to 40 km/h. The gear ratio of the transfer case is then changed from 1.00 in HIGH RANGE to 2.93. It is possible to switch from LOW RANGE to HIGH RANGE at speeds of up to 70 km/h.
The new, intelligent multiplate clutch behaves like an automatically controlled locking differential. It ensures that the new G 63 remains manoeuvrable for longer when off-road. The advantage is that the driver has more scope before having to engage the differential locks manually.
When the driver operates the switch for the centre differential lock, the multiplate clutch switches to a 100% locking effect. The locks at the front and rear axle differentials are differential locks with a dog clutch and a 100% locking effect. All the locks can be engaged individually while on the move, both in LOW RANGE and in HIGH RANGE, firstly centre, then rear axle and finally front axle differential.
The differential locks now respond to the switches even more rapidly, as they are electromechanically actuated and fully networked. An LED and the central driver's display indicate which lock is currently active.
Direct and with clear feedback: the AMG speed-sensitive steering
The electromechanical speed-sensitive steering installed in the G 63 for the first time has a variable ratio to ensure precise and authentic feedback. The steering servo assistance is reduced at high speeds, and continuously increases at low speeds. This means that comparatively little steering force is required at low speeds, and that the best possible control over the vehicle is maintained at high speeds. Steering power assistance is available in a choice of two modes - "Comfort" or "Sport". The relevant characteristics are automatically activated depending on the selected DYNAMIC SELECT driving mode, or can be personalised in "Individual" mode. In "Sport" the driver receives more direct feedback about the driving status.
Sporty and distinctive: the exterior design
Unmistakable design features give the new AMG G 63 its unique appearance: the boxy silhouette, the proud bonnet, external door hinges, round headlamps, mounted direction indicators, robust door handles, muscular protective strips with inserts in high-gloss black with a silver AMG emblem, the exposed spare wheel on the rear door with a stainless steel cover and three-dimensional Mercedes star.
The front section of the G 63 is characterised by the AMG-specific radiator grille and the AMG bumper with large side air inlets and trim in matt iridium silver. The headlamps, indicators and tail lights are in LED High Performance technology as standard. This lighting consumes less energy and has a particularly long service life.
MULTIBEAM LED headlamps are optionally available. These each use 84 individually controlled high-performance LED modules to illuminate the road surface automatically with an extremely bright and precisely directed beam of light, without dazzling other road users. That is because this individual control allows the light distribution of the left and right headlamps to be adapted separately, quickly and dynamically to suit the changing situation on the road. This improves safety for all road users.
With the enhanced fog light function, the MULTIBEAM LED technology also allows the headlamp on the driver's side to illuminate that side more actively, while masking any rise in the light beam. As a result, the outer half of the road surface is more brightly illuminated and back-glare from the light reflected from the fog is reduced.
Mercedes-AMG G 63 with further distinctive features
Other characteristics of the G 63 include the flared front and rear wheel arches, which create space for the larger, wider wheels. Running boards as standard, distinctive trim elements on the front and rear bumpers and metallic paintwork as standard round off the exclusive exterior. Other distinguishing features include the "V8 BITURBO" lettering on the front wings and the Mercedes-AMG G 63 model badge on the rear door. Red brake callipers, perforated brake discs and 22-inch wheels available for the first time round off the exterior design.
The G 63 looks particularly striking with the optional AMG Night package. In this case the headlamps, tail lights, indicator lenses, rear window and rear side windows are dark-tinted. The obsidian black paint finish on the exterior mirror housings, the spare wheel ring and the trim in the front and rear bumpers, together with the black-painted underride guard, emphasises the confident appearance which is rounded off by matt-black 21 or 22-inch wheels.
Sporty look with model-specific details: the interior design
The new G 63 has been given a completely newly designed, modern interior that echoes specific exterior features. The shape of the round headlamps is reflected in the side air vents, and that of the indicators in the tweeters on the dashboard. Hallmarks of the G 63 also include the grab handle in front of the front passenger and the chrome-highlighted switches for the three differential locks.
The completely redesigned dashboard has analogue tubes as dial instruments as standard. Optionally the fully digital Widescreen Cockpit with virtual instruments directly in the driver's field of vision and a central display above the centre console can be ordered. The two 12.3-inch displays visually blend into a single unit beneath a shared glass cover. The driver is able to choose from three different views – "Classic", "Sporty" and "Progressive" - and access the required information individually.
The new dimensional concept in the interior benefits all the occupants. The increase in length (+101 millimetres), width (+121 millimetres) and height (+40 millimetres) provides the basis for a significantly more airy and spacious impression than in the previous model.
