For 2005 model year, AMG revised G 55 AMG by adding the supercharger to the 5.4-litre V8 engine, increasing the output to 350 kW (469 hp). To differentiate G 55 AMG KOMPRESSOR from G 500 visually, AMG changed the radiator grille to three thick fins, added the embossed metal KOMPRESSOR lettering underneath V8 badge on the front fenders/wings, and introduced new light-alloy wheels in titanium grey and three new metallic paint colours (Calcite White, Periclase Green, and Teallite Blue).
