Every new AMG high-performance vehicle offers an outstanding mix of “more power from less fuel” – and the G 63 AMG is no exception. The “strong man” in the AMG model range has been further enhanced with the state-of-the-art powertrain of the new ML 63 AMG. The design has been comprehensively reworked, so that, for the first time in the 33-year history of the G-Class, AMG customers can enjoy a raft of future-oriented systems: spray-controlled petrol direct injection, the ECO start/stop function and generator management. The AMG 5.5-litre V8 biturbo engine develops a maximum output of 544 hp and a torque of 760 newton metres. This enables the new G 63 AMG to accelerate from zero to 62 mph in just 5.4 seconds, with a new top speed of 130 mph (electronically limited).
AMGSPEEDSHIFT PLUS 7G-TRONIC and ECO start/stop function
The vehicle’s driving performance features are matched by its impressive advances in the area of fuel economy. The fuel consumption of 20.4 mpg (NEDC combined) is a 2.7 mpg improvement on the predecessor model, representing fuel savings of 13 percent. This reduction can be attributed to the state-of-the-art biturbo eight-cylinder engine, along with the AMG SPEEDSHIFT PLUS 7G-TRONIC automatic transmission system, the generator management system and the ECO start/stop function. The seven-speed automatic gearbox features three drive modes and an automatic double-declutching function for downshifting, creating an incredible range of variability. In “Controlled Efficiency” (C) mode, the ECO start/stop function is active, shutting down the eight-cylinder engine when the vehicle is stationary. “C” mode is also characterised by smooth accelerator and transmission characteristics and early gear changes; the vehicle is usually started in second gear in this mode. The AMG instrument cluster includes a green “ECO” symbol, indicating when the ECO start/stop function is on.
In the Sport (S) and Manual (M) modes, the ECOstart/stop function is off, and the engine-transmission combination displays far greater agility. Short, precisely defined ignition and injection retardations mean shorter shift times when changing up at full load. The efficiency of the AMG SPEEDSHIFT PLUS 7G-TRONIC automatic transmission system is further enhanced with a new fuel economy converter with centrifugal pendulum, friction-reducing bearing and transmission oil thermal management.
The fascination of the characteristic sound of a V8 AMG
A glance at the AMG sports exhaust system will reassure any doubters that all these efficiency advances have not been at the expense of emotional appeal. The twin tailpipes on both sides at the rear put out the hallmark AMG eight-cylinder sound that means so much to the vehicle’s many admirers. The latest catalytic converter technology is used to ensure that the G 63 AMG meets both the EU 5 exhaust emissions standard and the requirements for the US market (LEV-II standard, on-board diagnosis II and lambda probe diagnosis).
New chassis settings, optimised acoustic comfort
The suspension/damper settings in the AMG Sports chassis have been adjusted for the more dynamic handling characteristics of the new model. To reduce vibration and noise impacts, the design engineers at Mercedes-AMG have also implemented a wide range of NVH (noise, vibration, harshness) measures. Optimised bearings for the automatic gearbox, transfer case and engine cut vibration and noise levels. All this ensures a more comfortable ride and helps to keep the driver fit and alert, particularly over long distances. The wheels and brakes are also completely new. The G 63AMG runs on new AMG 5×2 spoke light alloy wheels as standard equipment. The 9.5 x 20 titanium-grey-painted wheels with high-sheen finish are fitted with 275/50 R 20 tyres. As an exclusive special equipment option, the vehicle can be fitted with matt-black-painted AMG light alloy wheels with high-sheen rim flanges. The new AMG high-performance brakes deliver top performance in terms of deceleration, adjustable feed and endurance. All-round ventilated, perforated brake discs with dimensions of 375 x 36 millimetres at the front and 330 x 20 millimetres at the rear provide optimum thermal capability and outstanding deceleration values. The front axle is fitted with a six-piston fixed-calliper brake system taken from the ML 63 AMG, with a single-piston floating-calliper system on the rear axle. The brake callipers are painted red around the entire circumference, and are also available in silver.
Fully readjustedESP®with more comfort functions
The new generation of the G-Class also offers a range of exemplary safety features. For example, the luxury off-roader has a completely readjusted ESP®, with automatic control systems including the start-up assist and a HOLD function, both for easier hill starts. And in an emergency braking situation, when the driver suddenly releases the accelerator and hits the brake pedal, the brake system increases the pressure in the brake lines and applies the brake linings to the discs. This ensures maximum effect as soon as the brake is applied. This “pre-filling” function supports the Brake Assist, fitted as standard. For customers ordering the optional trailer coupling, the ESP® trailer stabilisation feature provides increased safety when the vehicle is pulling a trailer. This additional ESP® function detects the trailer as soon as the electric connector plug is inserted in the socket on the towing vehicle. The ESP® trailer stabilisation system uses the sensors of the ESP®, counteracting any fishtailing of the trailer at speeds higher than 40 mph by alternating brake application to the left and right front wheels. This is generally sufficient to eliminate the problem and prevent any further risk. In very severe fishtailing situations, the engine torque is also reduced and the towing vehicle is braked on all four wheels, to get the vehicle back to within a safe speed range as quickly as possible.
CharacteristicAMGstyling with the new face of the brand
The appearance of the eight-cylinder top-of-the-range model is also definitely up with the times. Following the example of the SL 63AMGand SL 65 AMG, the G 63 AMG has also taken on the new face of the AMG brand. The high-gloss black “twin-blade” radiator grille with four chrome inserts makes the new G-Class model instantly recognisable as an AMG. The grille design is consistent with the car’s classic contours, with an off-road look perfectly integrated into the vehicle’s overall appearance.
Another completely new feature is the AMG bumper, with three generously dimensioned openings as airflow inlets for the cooling module. Vertical high-gloss chrome stainless steel inserts create a distinctively masculine look for the G 63 AMG. New LED daytime running lamps are fitted below the bi-xenon headlamps. As before, only the AMG model has the characteristic wheel-arch flares, stainless-steel running boards and side protective strips with stainless-steel inserts. Other distinctive features include the “V8 BITURBO” logo on the front mudguard and G 63 AMG type plate on the rear door.
Stylish new-look interior with increased comfort
The interior features even more innovations in comparison with the predecessor model. Along with the facelift changes provided as standard, including the new instrument panel and state-of-the-art infotainment and assist systems, the G 63 AMG has an AMG instrument cluster with colour TFT screen, AMG main menu and separate gear display, plus white-lit AMG sills on all doors. The classy E-SELECT shift lever with the distinctive AMG medallion is a familiar feature from other models such as the SLS AMG. An exclusive on-board environment is created by the designo leather upholstery with ruffled leather door panelling. Options available for an even more stylish interior comprise the AMG carbon trim and the designo Exclusive package.
