Every G-Class has to conquer the Schöckl. Mercedes-Benz uses the 1,445 metre high local mountain near the Austrian city of Graz as a test track. The 5.6 km route includes gradients of up to 60 percent and lateral inclinations of up to 40 percent. During the development stage, a "G" has to endure a good 2,000 strenuous kilometres on this very demanding course. The new G-Class masters the route with noticeably more control and comfort.
