Mercedes has improved upon a legendary icon, the G-Class. The 2019 Mercedes G550 is an extraordinary machine, capable of incredible off-road feats, including climbing a 100% grade, which this video will discuss in detail. In order to climb a 100% grade, the right elements have to come together: the engine, the transmission, the 4WD system, the tires, and of course the overall package and weight distribution.
What is so special about climbing a 100% slope? What about the G-Class allows it to be capable of ascending such an incline? Can the G-Class actually do it? This video brakes it all down, from road testing to measure the vehicle's tires grip, to an analysis of the center of gravity. And to sum it all up, I provide 4 reasons why the G-Wagon is one my all time favorite vehicles.
Mercedes Press kit summarizes the off-roading prowess:
"The primary goal of development was to redefine the quality of the handling both on and off the road. This goal has been achieved: the new G-Class performs even better off-road, while on the road it is significantly more agile, dynamic and comfortable than its predecessor. The G thus remains a true G – thanks to its standard ladder-type frame, the three 100-percent differential locks and LOW RANGE off-road gear reduction.
The new suspension is a result of cooperation between Mercedes-Benz G GmbH and Mercedes-AMG GmbH. The result is an independent suspension with double-wishbone front axle in combination with a rigid rear axle. As part of their work, the engineers had the task of fighting for every millimetre, because off-road capability not least also means maximum ground clearance. The raising of the axles makes a decisive contribution in this respect, while requiring a strut tower brace in the engine compartment to achieve the ruggedness objectives.
The components of the double-wishbone front suspension are directly mounted to the ladder-type frame without a subframe. The lower wishbone's attachment points on the frame in Z-direction are positioned as high up as possible. This arrangement ensures good driveability beyond the asphalt. Specifically for the G-Class, the new front axle is designed in such a robust way that the off-road performance and off-road capabilities of its predecessor are maintained and partly even surpassed.
Equipped in this way and with a ground clearance of 270 mm to the front axle gear, the G-Class provides plenty of potential for maximum assertiveness and driving pleasure in off-road terrain.
The figures speak for themselves:
- Slope climbing ability of up to 100% on suitable surfaces
- Ground clearance between axles, plus 6 mm, now 24.1 cm
- Maximum fording depth now 70 cm when driving through water and mud, no less than an additional 10 cm
- Stable at tilt angles of 35°, plus 7°
- Angle of departure: 30°, angle of approach: 31°, plus 1°
- Break-over angle: 26°, plus 1°
Thanks to the independent suspension, it was possible to improve the rigidity of the body front end. A strut tower brace, known as a suspension bridge, now connects the front strut towers, which increases the torsional rigidity of the ladder-type frame.
At the rear, in contrast to the predecessor, the new rigid axle is controlled by four trailing arms on each side and a Panhard rod. This makes normal driving on the road even more comfortable. In off-road terrain, the rear spring jounce of 82 mm and rebound of 142 mm plus the ground clearance of 241 mm to the rear axle gear help to ensure a safe ride even in extreme situations."
