The Schöckl mountain near Graz (Austria) is the original testing ground of the Mercedes-Benz G-Class. Meet one of its test drivers, Erwin „Air“ Wonisch, who has been involved in the G-Class development since 1976. Erwin shows us around the Schöckl and lets us experience the sheer power, robustness and versatility of the mighty Geländewagen. Buckle up and hold tight while watching! ;-)
