G-Class Range Gets Euro 6-Ready Engine Options

All Mercedes-Benz G-Class models will in future offer up to 16 percent more power and lower fuel consumption. The range includes the G 500 with a new, powerful 4.0-litre V8 biturbo engine. All engines are compliant with the latest Euro 6 emissions standard. A new suspension setup, together with more sensitive Electronic Stability Programme control results in increased driving stability, safety and road comfort. The exterior and interior have also been given an upgrade. At the same time, an exclusive AMG special edition will be available.

G500-4

Mercedes-Benz’s classic off-roader is beginning a new chapter of its success story which spans more than 35 years. With its continuously improved technology and high-class equipment specification, this cult all-terrain vehicle has consistently satisfied the highest expectations of off-road fans. True to this tradition, a new 4.0-litre directly injected V8 biturbo engine already unveiled in the G 500 4×4² show car is now celebrating its world premiere in the G-Class.

AMGGT-4.0-Engine

The new 8-cylinder powerplant in the G 500 is based on the new generation of Mercedes-AMG V8 engines that have already coaxed exceptional levels of performance out of the Mercedes-AMG GT and Mercedes-AMG C 63. For use in the G-Class, the V8 has been modified to deliver 422 hp and 610 Nm of torque. Other standout attributes include a spontaneous response and high tractive power which are made possible by two turbochargers, which instead of being configured on the outside of the cylinder banks are arranged between them in the V – the so-called “hot inside V”.

This layout allows a compact design, optimal response and low exhaust emissions. High efficiency is ensured by Mercedes-Benz’s use of piezo direct petrol injection with spray-guided combustion. Maximum strength with lowest possible weight is guaranteed by the aluminium crankcase of the V8 engine. The cylinder bore surfaces feature Daimler’s NANOSLIDE® technology, which makes them twice as hard as conventional cast-iron linings. This minimises both internal friction and fuel demand.

The engines of the other G-Class models have likewise been further developed and improved in the interests of superior tractive power and optimised fuel economy:

  • the G 350 d benefits from a hike in output from 211 hp to 245 hp, with its torque climbing from 540 to 600 Nm.
  • The AMG G 63 now delivers an extra 27 hp with torque of 760 Nm.
  • Instead of 612 hp, the 12-cylinder powerplant in the AMG G 65 now puts out 630 hp with torque of 1000 Nm.

G500-3

The G 350 d, G 500 and AMG G 63 are equipped as standard with an ECO start/stop function that reduces fuel consumption and emissions by switching off the engine when the vehicle is at rest. As is typical of the G-Class, the new models retain the familiar sturdy basis of body and ladder-type frame, which still offers generous reserves to cope with the increased power. Also retained is the unrivalled off-road performance with permanent all-wheel drive, low-range gearbox and three differential locks that can be engaged/disengaged while on the move.

G500-2

The standard suspension setup has been revised with optimised shock absorbers for improved control of body movements and even greater on-road ride comfort. An adapted ESP setup makes for enhanced driving dynamics together with increased driving stability and road safety. Optimisations to ASR and ABS result in improved traction while shortening the stopping distance when braking.
