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 6x6, and they are now stepping up a gear with the G 500 4x4². The basic recipe for this overcomer of everything is simple: take the superior all-wheel-drive powertrain including portal axles from the 6x6 – take away one axle – and blend it all with a newly-developed variable chassis and the series-production G-Class body.
The 4.0 litre V8 biturbo engine in the G 500 4x4² 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 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, minimize the inner friction and thus the fuel required and facilitate maximum mileages.
Twin sidepipes on both sides in front of the rear wheels modulate the G-typical sound of the G 500 4x4² and master the entire repertoire of potent sports cars – from soft mumbling in neutral through sonorous humming in the partial-load range to emphatic booming when accelerating under full load.
In view of the key data for the chassis and powertrain it seems logical that the off-road world starts for the G 500 4x4² where other vehicles capitulate. But it is surprising that the new “G” puts in an absolutely convincing performance on the asphalt. With its Sport mode, the enhanced G-Class drives through bends so dynamically that the occupants feel as though they are in a sports car rather than in a cross-country vehicle.
This also applies to tours on unsurfaced slopes or snow-bound roads, in which case the performance of a high-powered rally car kicks in.
Permanent all-wheel drive, an off-road reduction in the transfer case, portal axles and three differentials lockable whilst on the move will not be found on conventional cross-country vehicles. Even the highest sand dunes are stormed by the show car with ease, whilst rocky terrain and water is driven through without any problems. The portal axles developed for versatile applications are the technical highlight of the G 500 4x4² show car. Therefore, on the G 500 4x4² the ground clearance rises to 450 millimetres and the fording depth to 1000 millimetres.
The new damper adjustment, derived from rally sport, has a decisive effect here: Two spring/damper struts running in parallel are used per wheel. One spring/damper strut works conventionally with set damper characteristics.
With this set-up, considerable kingpin inclination is possible between the settings SPORT and COMFORT, which the driver can select using a button in the centre console. The switching times between the two modes are record-breakingly low, at 15 milliseconds.
In visual terms the G 500 4x4² raises no doubts as to its passion. The voluminous tyres, the huge distance to the ground, the height of nearly 2.25 metres with a width of virtually 2.10 metres and the clear, straight design command respect right from the first glance. Further highlights: the trim with the integral LED light strips above the windscreen and the elaborate partially painted wheel-arch flarings – both in fine carbon fibre – plus the front bumper on the G 63 AMG and G 65 AMG models.
The interior appointments make a sportily luxurious impression. The G 500 4x4² offers an exclusive ambience with the designo Exclusive package. The seat bolsters and head restraints as well as the dashboard, centre console and armrests in the doors are styled in black designo leather with white contrasting topstitching. The seat surfaces and door panels are covered in DINAMICA and impress with their attractive diamond-design quilting.
In addition to this there is DINAMICA trim for the roof liner and the body pillars.
