The Mercedes-Benz G-Class, sometimes called G-Wagen (short for Geländewagen, "terrain vehicle"), is a mid-size four-wheel drive luxury SUV manufactured by Magna Steyr (formerly Steyr-Daimler-Puch) in Austria and sold by Mercedes-Benz. In specific markets, it has been sold under the Puch name as Puch G.

For better fuel consumption and lower emissions, the new 5.5-litre biturbo V8 replaced the supercharged 5.4-litre V88 for 2012 for better fuel consumption and lower emissions. AMG made some more changes to the exterior to give the Mercedes G 63 AMG a more "brawly" appearance: single horizontal fin with twin chrome edges in the middle of the radiator grille with a more prominent three-pointed star ornament in the middle, a new light-alloy wheel design, three enlarged airflow inlets on both sides and in the middle of the front bumper, vertical chrome stripes to cover the small bumper guards and exterior rear-view mirrors from the GL-Class and ML-Class.
