Outstanding response to the “Extreme-G”: the G 500 4×4² show car proved hugely popular with many customers and is set to enter series production.
A new addition to the extreme G-Class model family: the Mercedes-Benz AMG G 63 6×6 is gaining a sibling in the form of the Mercedes-Benz G 500 4×4². The series-production models of the G-Class provide the basis in the form of the body and ladder-type frame, which compensate for the considerably increased performance of the G 500 4×4² with no problem and without any type of reinforcements. The Mercedes-Benz AMG G 63 6×6 has contributed an adapted version of the permanent all-wheel drive powertrain with portal axles. In the superlative-studded history of the G-Class, the G 500 4×4² is the new highlight in the model range. The technical package consists of the all-wheel drive powertrain including portal axles and the new V8 engine.
The new model is powered by the new V8 powerpack with a displacement of four litres, direct injection and twin turbocharging. The efficient and clean 4.0-litre biturbo engine develops an output of 310 kW (422 hp) and maximum torque of 610 Newton metres, and meets the Euro 6 emissions standard including the maximum particulate limit prescribed from 2016. The eight-cylinder has a set of exclusive genes: it is based on the new generation of V8 engines developed by Mercedes-AMG that have already coaxed exceptional levels of performance out of the Mercedes-AMG GT and Mercedes-AMG C 63.
Also new is the chassis with dual spring/damper struts and adjustable damping. In the interior of the G 500 4×4², occupants enjoy comfort and an ambience on a par with a luxury saloon. In view of the key data for the chassis and powertrain it seems more than logical that the off-road world starts for the Mercedes-Benz G 500 4×4² where other vehicles give up. But it is surprising that the new “G” also puts in an absolutely convincing performance on the asphalt. Owing to the considerably wider track of the portal axles compared with the series-production car (plus 299 millimetres), the large 22-inch 325/55 R 22-sized wheels and the adjustable damping 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 a cross-country vehicle.
Permanent all-wheel drive, an off-road reduction in the transfer case, portal axles and three differentials lockable while on the move are not to be found in conventional cross-country vehicles. The portal axles developed for versatility in operation complement the off-road portfolio of Mercedes-Benz and are the technical highlight of the G 500 4×4².
Unlike on conventional rigid axles, the wheels are not at the height of the axle centre but are instead situated much further below on the axle heads thanks to the portal transmission. As a result the ground clearance of the G 500 4x4² increases to 450 millimetres and the fording depth – or rather the diving depth – to 1,000 millimetres.
Since its launch in 1979, the G-Class has made history and is the foundation for the entire Mercedes-Benz SUV family. More than 250,000 vehicles have been delivered to customers since the first model of the G-Class was introduced. Mercedes-Benz keeps this legendary off-roader series in peak technical form with systematic further development and high quality appointments.
The G-Class now offers up to 16 percent more power and a lower fuel consumption. All engine variants are fit for the future, for from now on they meet the requirements of the highest Euro 6 emissions standard. A new suspension setup together with more sensitive ESP control results in increased driving stability, safety and road comfort.
