Mercedes-Benz G63 AMG

High tech for the AMG off-road classic: the new G63 AMG impresses with state-of-the-art drive technology, expressive design and increased fuel economy. All this is largely attributable to the AMG 5.5‑litre V8 biturbo engine delivering 400 kW/544 ps (536 hp) and the AMG SPEEDSHIFT PLUS 7G-TRONIC automatic transmission system. Even more exclusive is the new G65 AMG: its AMG 6.0-litre V12 biturbo engine delivers 450 kW/612 ps (603 hp) and reaches a maximum torque of 1000 newton metres – a record in the off-road segment.

Every new AMG high-performance vehicle offers an outstanding mix of “more power from less fuel” – and the G63 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 400 kW/544 ps (536 hp) and a torque of 760 newton metres. This enables the new G63 AMG to accelerate from zero to 100 km/h in just 5.4 seconds, with a new top speed of 210 km/h (electronically limited).

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 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. Optimized 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 G63 AMG runs on new AMG 5x2 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 tires. 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 millimeters at the front and 330 x 20 millimeters at the rear provide optimum thermal capability and outstanding deceleration values. The front axle is fitted with a six-piston fixed-caliper brake system taken from the ML 63 AMG, with a single-piston floating-calliper system on the rear axle. The brake calipers are painted red around the entire circumference, and are also available in silver.

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 65 km/h 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.

The appearance of the eight-cylinder top-of-the-range model is also definitely up with the times. Following the example of the SL 63 AMG and SL 65 AMG, the G63 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 recognizable 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 G63 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 G63 AMG type plate on the rear door.

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 G63 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.

Even more exclusive, and also the world’s most powerful production off-road vehicle, is the new G65 AMG. With maximum output of  450 kW/612 ps (603 hp) and maximum torque of 1000 newton metres, the top-of-the-range V12 model delights the connoisseur with its incomparably dynamic handling characteristics. The G65 AMG accelerates from zero to 100 km/h in just 5.3 seconds, and has a top speed of 230 km/h (electronically limited). This is the first G-Class vehicle to be equipped with the AMG 6.0-litre V12 biturbo engine, which features new exhaust turbochargers with increased spiral cross-section, flow-optimized wastegate channels, multi-spark ignition with twelve double-ignition coils and a higher-power engine control unit. The result is enhanced combustion, leading to smoother running and power delivery. The high-quality carbon and aluminium engine cover adds a final visual touch to this extensive package of new features. As in the G63 AMG, the AMG SPEEDSHIFT PLUS 7G‑TRONIC automatic transmission system is responsible for power transmission to all four wheels.

In terms of appearance, the G65 AMG is differentiated from its V8 sister model by the high-gloss chrome radiator grille, the 9.5 x 20 AMG five-spoke light alloy wheels, painted titanium grey with high-sheen finish, its 275/50 R 20 tires and the V12 BITURBO logo on the mudguards. Interior features include the welcome display with exclusive AMG V12 BITURBO animation, the designo leather exclusive upholstery and the leather instrument panel trim. A unique special touch is the distinctively V12 diamond design of the seats, including the impressed AMG medallion on the headrests. This distinctive upholstery feature is repeated on the door central panels. A comprehensive range of standard equipment includes black piano lacquer designo trim features and designo foot mats with a V12 badge. An exclusive special option from the AMG Performance Studio is AMG light alloy wheels, painted matt black with high-sheen rim flanges.
