Mercedes-Benz has expanded the powertrain line-up of its new G-Class with an environment friendly diesel variant. The brand new G 350 d (gasoline consumption, mixed: 9.Eight-9.6 l/100 km; mixed CO2 emissions: 259-252 g/km) is provided with an OM 656 diesel(earlier submit). The fashions might be accessible to order beginning in January 2019 and can arrive in dealerships in spring.
Because of this, the G-Class mannequin vary now provides patrons a selection between the G 500 (gasoline consumption, mixed: 12.1-11.5 l/100 km, mixed CO2 emissions: 276-263 g/km), the AMG G 63 (gasoline consumption, mixed: 13.1 l/100 km, mixed CO2 emissions: 299 g/km) and the brand new G 350 d.
The traits of the engine embody the stepped-bowl combustion course of, two-stage exhaust turbocharging in addition to the usage of CAMTRONIC variable valve timing. This heats up the exhaust system with out driving up gasoline consumption. The additional superior NANOSLIDE cylinder wall coating additionally reduces friction losses within the piston/cylinder wall system and reduces gasoline consumption.
The brand new in-line six-cylinder diesel makes the off-roader essentially the most environment friendly “G” thus far. It produces an output of 210 kW (286 hp) and with a peak torque of 600 N·m between 1200 and 3200 rpm is as highly effective as by no means earlier than.
The brand new six-cylinder diesel engine is designed to adjust to future emissions laws (RDE – Actual Driving Emissions). All parts related for environment friendly emissions discount are put in immediately on the engine. This contributes to sooner effectiveness of the catalytic converter and the diesel particulate filter.
Because of the integral expertise strategy comprising the brand new stepped-bowl combustion course of, dynamic multi-path exhaust fuel recirculation and near-engine emission management system, additional lowered consumption figures with low emissions are doable. With the near-engine insulated configuration, the emission management system has little warmth loss and best working situations.
Probably the most environment friendly G. Due to additional enhanced emission management applied sciences, the highly effective six-cylinder unit from the trendy OM 656 engine household stays under all the emission limits of the present Euro 6d-TEMP commonplace even in demanding driving conditions and environmental situations. That is achieved with an extra selective catalytic discount (SCR) converter with an ammonia slip catalyst (ASC) within the exhaust tract of the GLE.
In ECO drive mode, the gliding operate helps to save lots of further gasoline. When the motive force’s foot leaves the accelerator pedal, the transmission’s clutch disengages. This reduces the engine velocity to idling degree, and the driving resistance is lowered by the compression and frictional forces of the engine whereas coasting. The G-Class “glides”, utilizing its personal, present kinetic power for a sure distance. It rolls for a measurably longer distance than when coasting. This ends in additional gasoline financial savings. The clutch is re-engaged as quickly as the motive force operates the accelerator or brake pedal.
Partly as a result of new quiet and harmonious diesel engine, the G-Class proves to be extraordinarily comfy, even on lengthy distances. When driving, the exhaust system and the engine, which can also be prepared to rev at greater engine speeds, produce a lot much less noise and vibrations within the inside. To cut back engine noise, the engine mounts of the diesel engine are actively managed for the primary time.
At speeds under 5 km/h, they’re set to smooth to optimally dampen the switch of torsional vibrations to the ladder-type body at low engine speeds. At greater engine speeds, the 2 engine mounts are robotically made stiffer, which has constructive results on the vibrational consolation and the driving dynamics.
9G-TRONIC. For the transmission of energy, the 9G‑TRONIC computerized transmission with torque converter was particularly tailored to satisfy the wants of the off-roader. The builders used a devoted software program utility to shorten the shift and response occasions of the 9-speed transmission and make the G-Class appear much more energetic.
The huge transmission ratio not solely makes driving quieter and extra comfy particularly at low engine speeds, it concurrently additionally contributes to lowering gasoline consumption. Particularly in first gear, the off-roader responds to accelerator pedal instructions noticeably higher, which prospects will admire particularly when pulling away from a visitors mild, for instance. The “G” is now additionally considerably extra agile throughout transient sprints below partial load.
The brand new switch case is flange-mounted on to the 9G-TRONIC. It’s designed to ship 40% of the drive torque to the entrance axle and 60% to the rear axle. This configuration notably advantages the dealing with traits on the street. The everlasting all-wheel drive ensures most traction. The low-range off-road discount gear significantly will increase torque on the drive wheels.
DYNAMIC SELECT is now accessible with as much as 5 drive modes for the G-Class as commonplace. This permits adjusting the automobile traits in seconds on the contact of a button, because the system modifies the traits of the engine, transmission, suspension, and steering on the driver’s behest. As well as, the G-Class provides a number of latest driver help programs. For instance, Energetic Braking Help is ready to forestall impending collisions or mitigate their penalties, and help the motive force throughout emergency braking. If obligatory, it would brake autonomously if the motive force takes no motion to defuse a detected harmful scenario.
Particularly for the G-Class, the brand new entrance axle is designed in such a sturdy method that the off-road efficiency and off-road capabilities of its predecessor are retained and partly even surpassed. The parts of the double-wishbone entrance suspension are immediately mounted to the ladder-type body with no subframe. The decrease wishbone’s attachment factors on the body in Z-direction are positioned as excessive up as doable. This association ensures good driveability past the asphalt.
On the rear, in distinction to the predecessor, the brand new inflexible axle is managed by 4 trailing arms on all sides and a Panhard rod. This makes regular driving on the street much more comfy. Off the street, the rear spring jounce of 82 mm and rebound of 142 mm plus the bottom clearance of 241 mm to the rear axle gear assist to make sure a secure experience even in excessive conditions.
The G-Class will not be solely the passenger automobile mannequin collection with by far the longest manufacturing run within the historical past of Mercedes-Benz, but additionally the forerunner of all SUVs bearing the three-pointed star—because of this all Mercedes off-road fashions function the upper-case G of their title.
