G 63 AMG and G 65 AMG

G-Class Summit

High tech for the AMG off-road classic: the new G 63 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 hp) and the AMG SPEEDSHIFT PLUS 7G-TRONIC automatic transmission system. Even more exclusive is the new G 65 AMG: its AMG 6.0-litre V12 biturbo engine delivers 450 kW (612 hp) and reaches a maximum torque of 1000 Nm (738 lb-ft) – 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 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 400 kW (544 hp) and a torque of 760 Nm (561 lb-ft). This enables the new G 63 AMG to accelerate from zero to 100 km/h (62 mph) in just 5.4 seconds, with a new top speed of 210 km/h/ 130 mph (electronically limited).

The new G 63 AMG outperforms the G 55 AMG KOMPRESSOR by 27 kW (37 hp) and 60 Nm (44 lb-ft). Its direct predecessor was a clear favourite for G-Class purchasers, with a sales ratio of over 40 percent.

AMG SPEEDSHIFT 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 13.8 l/100 km (17.04 mpg/US, 7.24 km/l) (NEDC combined) is a reduction of 2.1 litres 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 ECO start/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.Mercedes-Benz G 63 AMG (W 463) 2012

The wheels and brakes are also completely new. The G 63 AMG 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 readjusted ESP® with more comfort functionsMercedes-Benz G 63 AMG (W 463)

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 (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.
