A look at the key data of the G 63 AMG 6×6 makes it clear that this model’s off-road world begins at a point where anything less than a vehicle with caterpillar tracks would have to capitulate. 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 which one seeks in vain in conventional cross-country vehicles. Together, they 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. A case in point is the drive train: 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.
