"Talk to anyone at AMG, and he will tell you the target vehicle for the ML63 AMG is the Porsche Cayenne Turbo. Forget other sporty utes such as the Range Rover Sport, the Jeep Grand Cherokee SRT8, or the BMW X5 4.8is: AMG focused on one truck, and one truck alone. The ML63 was even developed on the fearsome Nordschleife of the Nürburgring, where it laps the 12.9-mile circuit in “about 8 minutes, 40 seconds.” Not so long ago, that was a good Porsche 911 time."
