Citing the sales success of G 500 in the United States and the absorption of AMG into DaimlerChrysler AG, Mercedes-Benz began to expand the AMG versions to several models, including G-Class.
To coincide with the official launch of G-Class in the United States, Mercedes-Benz introduced G 55 AMG along with G 500 in 2001 for 2002 model year.
The G 55 AMG visually did not differ from G 500 other than side exhaust pipes, wider tyres, AMG five-spoke wheels, chrome tip at bottom of front bumper, and AMG lettering in the rear.
G 55 AMG became the favourite of celebrities and wealthy people.

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).
The 0–100 km/h acceleration is reduced from 7.4 to 5.6 seconds.
Yet, the top speed remained at 210 km/h.
The engine was upgraded again for 2006 to 368 kW (493 hp) then again to 373 kW (500 hp) for 2008.
