Before the 2019 Mercedes-Benz G-Class is unveiled next week at the Detroit motor show (NAIAS 2018), Mercedes-Benz has outlined the new SUV’s off-road credentials, along with some camouflaged shots of the vehicle.
We’ve already seen the new G-Class with no covering, but the statistics make for some interesting reading.
The German car-maker says that the new G-Class has been comprehensively tested using a 1,445 metre high local mountain near the Austrian city of Graz, called the Schöckl.
A 5.6 km test route uses 60 percent gradients with some side angles up to 40 percent, with the G-Class enduring aroud 2000km of testing.
We already know that the G-Class is being built on a ladder frame arrangement, having three 100-percent differential locks and a low-range transfer case.
But the suspension, we’re told, is actually a collaboration between Mercedes-Benz Mercedes-AMG
So, what’s special about it?
We’re glad you asked. Up front is independent suspension with a double-wishbone axle, but the rear is a rigid rear axle.
This serves to not only add chassis rigidity, but also maximises ground clearance and allows good articulation.
The front axle is fixed directly to the ladder frame high up, which stops wallowing on the road, but with adaptive suspension, it still allows enough grip and vertical movement off-road.
The rear axle has four longitudinal control arms on each side and a Panhard rod to stop the rear axle wandering during tough tracks.
The new G-Class also gets what MB calls G-Mode, which activates as soon as one of the diff locks (or low range) has been activated.
It holds onto the gears, and adjusts the throttle response and damping automatically to suit off-road driving. Apparently, this makes it easier to control off-road, especially if you’re not an experience bush-basher.
In addition, low-range (2.93:1) can be switched on once the vehicle has been shifted to neutral at speeds of up to 40 km/h.
And if you forget to switch back to high range, you can do that on the fly at up to 70 km/h.
According to Merc, here are the figures buyers need to know.
