Mercedes-Benz G 63 AMG and G 65 AMG are vehicles which are delivering outstanding mix of "more power from less fuel".

The design of the 2012 Mercedes-Benz G63 AMG is reworked, and now features spray-controlled petrol direct injection, ECO start/stop function and generator management.

It is equipped with AMG 5.5-litre V8 biturbo engine which effortlessly develops a maximum output of 400 kW (544 hp) and a torque of 760 Nm (561 lb-ft).

Therefore it is no surprise that this exceptional vehicle is able to accelerate from 0 to 100 km/h in just 5.4 seconds. Its new top speed is 210 km/h.

Although this vehicle delivers a powerful performance, its fuel consumption is also impressive: just 13.8 litres per 100 kilometres. This is 2.1 litres less than its predecessor model produced. The reduction is a result of 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.

First, the seven-speed automatic gearbox features three drive modes and an automatic double-declutching function for downshifting. Whan it is in "Controlled Efficiency" (C) mode, the ECO start/stop function is active, shutting down the eight-cylinder engine when the vehicle is stationary. In addition, the AMG instrument cluster also includes a green "ECO" symbol, indicating when the ECO start/stop function is on.

There are also two other modes: the Sport (S) and Manual (M) modes. Whan they are on, the ECO start/stop function is off, and the engine-transmission combination displays enhanced agility.

The efficiency of the AMG SPEEDSHIFT PLUS 7G-TRONIC automatic transmission system is improved with a new fuel economy converter with centrifugal pendulum, friction-reducing bearing and transmission oil thermal management.

Furthermore, AMG sports exhaust system includes twin tailpipes on both sides at the rear. The suspension/damper settings in the AMG Sports chassis have been modified for the more dynamic handling characteristics.

In addition to these modifications, the wheels and brakes are also completely new. This powerful Mercedes-Benz machine runs on new AMG 5x2 spoke light alloy wheels. They come 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 option, the vehicle can be fitted with matt-black-painted AMG light alloy wheels with high-sheen rim flanges.

Moreover, this Mercedes-Benz vehicle comes equipped with a new AMG high-performance brakes. They deliver top performance in terms of deceleration, adjustable feed and endurance.

The high-gloss black "twin-blade" radiator Mercedes-Benz grille now comes with four chrome inserts. This actuallt makes it AMG recognizable.

Another new feature is the AMG bumper. In particular it has three generously dimensioned openings as airflow inlets for the cooling module. The vertical high-gloss chrome stainless steel inserts give the G63 AMG powerful stance.

Of course, the interior was also completely transgormed and now includes more innovations in comparison with the predecessor model. There is a new instrument panel and state-of-the-art infotainment and assist systems. In addition to them, G 63 AMG comes with an AMG instrument cluster with colour TFT screen, AMG main menu and separate gear display, plus white-lit AMG sills on all doors.

The cabin looks even more comfortable, thank to the designo leather upholstery with ruffled leather door panelling. There are also other options available for an even more stylish interior.
