The new in-line six-cylinder diesel makes the icon the most efficient “G” so far. It produces an output of 210 kW (286 hp) and with a peak torque of 600 Newton metres between 1200 and 3200 rpm is as powerful as never before.
The new six-cylinder diesel engine is designed to comply with future emissions legislation (RDE – Real Driving Emissions). All components relevant for efficient emissions reduction are installed directly at the engine. This contributes to faster effectiveness of the catalytic converter and the diesel particulate filter. Thanks to the integral technology approach comprising the new stepped-bowl combustion process, dynamic multi-path exhaust gas recirculation and near-engine emission control system, further reduced consumption figures with low emissions are possible. Thanks to the near-engine insulated configuration, the emission control system has little heat loss and ideal operating conditions.
Thanks to further enhanced emission control technologies, the powerful six-cylinder unit from the modern OM 656 engine family remains below all of the emission limits of the current Euro 6d-TEMP standard even in demanding driving situations and environmental conditions. This is achieved with an additional selective catalytic reduction (SCR) converter with an ammonia slip catalyst (ASC) in the exhaust tract of the GLE. The SCR catalyst (Selective Catalytic Reduction) reduces the nitrogen oxides (NOx) in the exhaust gas. To this end, AdBlue®, an aqueous urea solution, is fed into the system. It chemically converts the nitrogen oxides in the exhaust gas, thus releasing ammonia, which reduces up to 80 percent of the nitrogen oxides into harmless nitrogen and water in the downstream SCR catalytic converter. The filler neck for the AdBlue® is integrated into the external tank recess of the vehicle, which makes straightforward filling at the fuel pump possible.
In ECO drive mode, the gliding function helps to save additional fuel. When the driver’s foot leaves the accelerator pedal, the transmission’s clutch disengages. This reduces the engine speed to idling level, and the driving resistance is reduced by the compression and frictional forces of the engine while coasting. The G-Class “glides”, using its own, current kinetic energy for a certain distance. It rolls for a measurably longer distance than when coasting. This results in further fuel savings. The clutch is re-engaged as soon as the driver operates the accelerator or brake pedal.
For the transmission of power, the 9G‑TRONIC automatic transmission with torque converter was specifically adapted to meet the needs of the off-road icon. The developers used a dedicated software application to shorten the shift and response times of the 9-speed transmission and make the G-Class seem even more lively. The wide transmission ratio not only makes driving quieter and more comfortable especially at low engine speeds, it simultaneously also contributes to reducing fuel consumption. Especially in first gear, the off-roader responds to accelerator pedal commands noticeably better, which customers will appreciate especially when pulling away from a traffic light, for example. The “G” is now also significantly more agile during brief sprints under partial load.
The new transfer case is flange-mounted directly to the 9G-TRONIC. It is designed to send 40 percent of the drive torque to the front axle and 60 percent to the rear axle. This configuration particularly benefits the handling characteristics on the road. The permanent all-wheel drive ensures maximum traction. However, the “G” would not be a “G” if it did not have even more in store. The low-range off-road reduction gear considerably increases torque at the drive wheels, which e.g. makes very difficult terrain negotiable.
What began more than 40 years ago with a cooperation agreement between then Daimler-Benz AG and Steyr-Daimler-Puch in the Austrian city of Graz is now a story peppered with superlatives and milestones. At the time of its market launch, in the spring of 1979, it was available with a choice of four engine variants covering a performance range from of 53 kW/72 hp to 115 kW/156 hp. Customers had the option of a Cabriolet with a short wheelbase or Station Wagon models with short or long wheelbase. The consortium decided on the simple but distinctive name “G”, standing for “Geländewagen” (off-road vehicle). At that time nobody could have guessed that this was an almost visionary decision in view of the later change in the nomenclature of Mercedes-Benz passenger cars classes, using just a single letter.
