The Mercedes-Benz G-Class turns 40. 40 years of performance. 40 years of passion. 40 years stronger than time. Condensed in one film. Happy birthday to the ageless Mercedes-Benz. Since 1979 the G-Class has thrilled its fans with its outstanding driving characteristics and impressive off-road capabilities. Even 40 years later, this iconic off-roader from Mercedes-Benz can do more than other vehicles.
