2018 Mercedes AMG G 63

by staff writer JP

The Mercedes-AMG G-Class has undergone the greatest change in its history – whilst remaining true to being a performance off-road vehicle

The G 63 underpins its position with the powerful drive system, the newly developed AMG suspension and AMG-specific transmission modes. Along with a new interior cockpit. The basis for the hallmark AMG Driving Performance  is provided by the 585 hp, 4.0 litre V8 biturbo engine.

With three differential locks and using a rear-biased (40:60) all-wheel drive and fast-shifting 9 speed automatic transmission. The double wishbone independent front suspension make use of the adaptive adjustable damping beautifully. Packaged in a design creating strong highlights with the AMG-specific radiator grille. Looks fantastic with flared wheel arches, striking side pipes on the exhaust system and specced with 22 inch wheels.

The AMG 4.0 litre V8 biturbo engine now also replaces the previous 5.5 litre V8 biturbo engine in the G 63. Delivering a maximum torque of 850 Nm, available across a wide rev range between 2,500 and 3,500 rpm. An impressive time for 0 to 62 mph in 4.5 seconds, topping out at 149 mph with the AMG Driver’s package.

"It was important for us to tie in with the original character on account of the cult status the G 63 enjoys with our customers and fans"
Tobias Moers, CEO of Mercedes?AMG GmbH

The two turbochargers are not positioned on the outside of the cylinder banks, but inside the cylinder ‘V’. Providing a compact engine design and quick response of the turbochargers, benefiting lower exhaust emissions.

Two twin scroll turbochargers are used for optimal response; the housing divided into two parallel flow channels. Combined with two separate exhaust pipes, this makes it possible to control the exhaust on the turbine wheel separately. The result is increased output by virtue of improved cylinder charging with fresh mixture, with torque at low revs.

For more efficiency, Mercedes-AMG has equipped the V8 engine with the AMG Cylinder Management cylinder deactivation system. In economy mode, cylinders two, three, five and eight are deactivated, which significantly lowers the fuel consumption. The combined fuel consumption is 13.2 l/100 km, and the combined CO2 emissions 299 g/km.

The AMG SPEEDSHIFT TCT 9G transmission is used in the G 63. This has a model-specific software application delivers very short shift times. The multiple downshift function allows more spontaneous bursts of speed. When the double declutching function is set to ‘Sport’ or ‘Sport Plus’ mode, it makes for a great experience. The wide ratio spread allows a choice of a very sporty or a very comfortable and efficient driving experience. In all transmission modes the G 63 moves off in first gear so as to ensure a dynamic sprint from a standstill whenever required. Manual mode can be selected using a separate switch; the gears changed using the paddles on the steering wheel. Moreover, the transmission stays in the selected gear and does not automatically shift up when the engine speed reaches the limit.

The intelligent multiplate clutch behaves like an automatically controlled locking differential. It ensures that the new G 63 remains manoeuvrable for longer when off-road. The advantage is that the driver has more scope before having to engage the differential locks manually. The differential locks now respond to the switches even more rapidly, as they are electromechanically actuated and fully networked. An LED and the central driver’s display indicate which lock is currently active.

The new G 63 performs even better when off-road, and on the road it is more dynamic and comfortable than its predecessor. For the first time the front axle has an independent, double wishbone suspension; a rigid axle with a five-link suspension is used at the rear. This makes normal driving on the road even more comfortable. When off-road, the rear spring compression of 82 mm and rebound of 142 mm plus the ground clearance of 241 mm to ensure a safe ride even in extreme situations. To reduce body roll, the G 63 has additional transverse stabilisers at the front and rear axles.

The G 63 looks particularly striking with the optional AMG Night package. The headlamps, tail lights, indicator lenses, rear window and rear side windows are dark-tinted. The obsidian black paint finish on the exterior mirror housings, the spare wheel ring and the trim in the front and rear bumpers, emphasises the confident appearance which is rounded off by matt-black 21 or 22-inch wheels.

Try and get your hands on the exclusive ‘Edition 1’ special. With the combination of equipment details and decorative red stripes. Matched with matt black 22-inch forged wheels in a cross-spoke design. Inside, the theme continues as red contrasting topstitching on the dashboard, door panels and rear seats is used. The carbon-fibre trim has highlights in red and the Performance steering wheel has a red 12 o’clock marking.
