All we have still have some time to wait before the 2012 Mercedes ML63 AMG makes its official debut, spy photographers have captured photos of the model undergoing a bit of track testing on the infamous Nurburgring. While heavy masking still hides much of the SUV’s styling cues, under the hood we can expect Mercedes-AMG’s new twin-turbo V8 that produces 536 horsepower and 590 lb.-ft. of torque. There’s also talk of the AMG Performance Package making its way onto the next ML63 AMG, which if true, would boost output to 563 hp (420 kW, 571 PS) and up to 900 Nm (664 lb-ft) of torque.
