The new Mercedes-Benz G 63 AMG 6×6 is a near-series show vehicle. It features six driven wheels, an off-road low-range ratio in the transfer case, portal axles, five differential locks which can be engaged on the move and a tyre-pressure control system which allows the pressure in the huge 37-inch tyres to be adjusted in record time while the vehicle is running. All these are features together ensure that the G 63 AMG 6×6 has driving dynamics which are more than a match for the toughest terrain.
As a result, the show vehicle is able to storm up the highest sand dunes with ease while sand tracks hold no fears thanks to its unshakable directional stability. Rocky terrain is negotiated with all the agility of a mountain goat; fording a river becomes almost child’s play thanks to the impressive fording capability of one metre. And anyone exploring the on-road performance is certain to be impressed by the catapult-like acceleration of this 3.85-tonne pickup.
Despite its unique drive technology, the show vehicle does not actually represent a new development in terms of technology. After 34 years of G-Class production, there is such a large array of G parts to draw on that the G 63 AMG 6×6 uses almost exclusively series-production components under the skin; The AMG V8 biturbo engine with 400 kW (544 hp) and 760 newton metres of torque, the AMG Speedshift Plus 7G-Tronic automatic transmission paired with the front drive system from the G 63 AMG and a rear twin drive train from the 6×6 version which has already proven its reliability in service with users such as the Australian army. Plus the ingenious portal axles, which also have military origins, here making their debut in a civilian vehicle.
The chassis is largely based on the current production configuration, the only difference being that the helical springs and dampers have been adjusted to take account of the changed characteristics of the three-axle model. For the springs, too, the engineers were able to draw on the comprehensive array of G parts, which includes no less than 15 different spring rates. While the front axle takes over the reinforced springs from an armoured special-protection variant, the first rear axle has been given a significantly harder spring rate and the second rear axle a softer one. This set-up, together with the rally-proven, adjustable gas-pressure shock absorbers, results in a perfect symbiosis of sporty dynamism and composed comfort, on or off the road.
The G 63 AMG 6×6 welcomes its occupants aboard with an exclusive ambience of classic red or light brown designo leather with contrasting topstitching and attractive diamond-pattern quilting. The four electrically adjustable individual seats are heated and ventilated. The rear compartment is equipped with a special centre console while the roof liner and pillars are finished in an Alcantara covering.The rear panel is trimmed in leather.
The response to the near-series show vehicle will determine if and when the Mercedes-Benz G 63 AMG 6×6 enters small-series production.
