Stuttgart, 22 February 2015: Only a G-Class can be better than a G-Class. This is the credo followed by the developers with the Mercedes-Benz G 63 AMG 6×6, and they are now stepping up a gear with the G 500 4×4². The basic recipe for this overcomer of everything is simple: take the superior all-wheel-drive powertrain including portal axles from the 6×6 – take away one axle – and blend it all with a newly-developed variable chassis and the series-production G-Class body. A large pinch of V8 power with 310 kW (422 hp), a set of 22-inch 325/55 R 22-sized wheels, carbon-fibre body parts and then just gourmet ingredients from the seductive designo Exclusive range for the interior – and the 5-star menu for all off-road enthusiasts is ready.
A new addition to the extreme G-Class model family: the G 63 AMG 6×6 has a model brother in the form of the G 500 4×4². The near-series show car is a new highlight in the superlative-rich history of the G-Class and blends all the advantages of the model series. The series-production models of the G-Class supply the unshakeable foundations in the form of the body and ladder-type frame, which compensate for the considerably increased performance of the G 500 4×4² without any problem and also without any type of reinforcements. The G 63 AMG 6×6 donates an amended version of the ruggedly determined permanent all-wheel-drive powertrain with portal axles. The engine compartment houses a completely new V8 engine with a displacement of four litres, direct injection and biturbocharging. Also new is the chassis with dual spring/damper struts and adjustable damping. Finally, in the interior, the G 500 4×4² occupants enjoy comfort and an ambience on a par with a luxury saloon.
The 4.0 litre V8 biturbo engine in the G 500 4×4² stands out for its sublime power delivery, the targeted lightweight construction, as well as its high efficiency. The newly developed eight-cylinder features twin turbochargers which are not mounted on the outside of the cylinder banks but rather inside the V configuration – what is known as the ‘hot inside V’. The advantages lie in the compact engine design, the optimum response and the low exhaust gas emissions. The piezo direct petrol injection used exclusively at Mercedes-Benz is responsible for the mixture formation. The spray-guided combustion process has been enhanced in the third generation to meet all future statutory requirements. In series production, the highly efficient and economical 4.0-litre V8 biturbo engine would meet the Euro 6 emission standard, including the maximum particulate emissions level that will not take effect until 2016.
The V8 crankcase consists of an aluminium alloy and ensures maximum strength with the lowest possible weight. The cylinder walls in NANOSLIDE technology are twice as hard as conventional cast-iron cylinder liners, minimise the inner friction and thus the fuel required and facilitate maximum mileages. NANOSLIDE was developed by Daimler starting in the year 2000 and has so far been used successfully and reliably in over 200,000 engines since 2006.
The Mercedes-Benz G-Class development department located in Graz is the centre of competence where all things “G” are concerned and is responsible for the development and series support of the legendary cross-country vehicle. Furthermore, Graz in Austria has been the production location for all civilian and commercial G-Class vehicles since 1979. Whether and when the decision on series production of the Mercedes-Benz G 500 4×4² will be made depends on the reaction which the near-series show car receives.
