Mercedes-Benz G 63 AMG 6x6: Complete Specs Out

The mighty Mercedes-Benz G63 AMG 6x6 created a sensation all over when it debuted ahead of 2013 Geneva Motor show, and now the company has officially revealed all the specifications and details about the car. The mean machine churns out the maximum power output of 544 horsepower to all six wheels, deriving its power from a twin-turbocharged 5.5-litre V8 engine.

The Mercedes-Benz G 63 AMG 6x6 is based on a similar platform the Merc builds the vehicle for the Australian army. So such a platform helps the vehicle become superior off-roader which also assures a superb refinement.

544bhp, a 6x6 drive, low-range ratio, five differential locks, portal axles, tyre pressure control system and a special chassis allow this pickup to make good progress in environments where the concept of individual mobility norm ally bites the dust as soon as the road ends. Thanks to the wealth of interior enhancements from the AMG stable, the occupants can enjoy the highest possible degree of comfort, even when negotiating the worst that the combined forces of topography and meteorology can throw at them .

They are also the source of the up-to-date interior concept with the contemporary dashboard featuring impressive new instruments and a large, central colour display. Unreserved robustness as well as practicality and a can-do attitude to off-road driving are the traits inherited from the military and the commercial G-Class models. Finally, the renowned Mercedes-AMG luxury and performance division contributes the superior engine technology and the interior which is as luxurious as it is comfortable.

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 6x6 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 6x6 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.
