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 litres per 100 kilometres (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.
The wheels and brakes are also completely new. The G 63 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 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.
