By 1999, AMG introduced the high-performance G55, which paved the way for the now-iconic G63. However, the 2002 G63 AMG V12 set itself apart, as it was never advertised or publicly sold.

the AMG G55 was upgraded to a supercharged 5.4-liter V-8 that made 469 hp; and an even more powerful AMG G63 trim with a 544-hp, twin-turbo 5.5-liter V-8 debuted for 2013.
