Spy Shots: Mercedes-Benz ML AMG snapped with less disguise

Mercedes-Benz is in the process of updating the AMG side of the family, including the replacement of its 6.2-liter engines with the more efficient 5.5-liter, twin-turbocharged V8. One of the models set to receive the new mill is the 2012 M-Class, and photogs posted outside the Nürburgring have caught the revised SUV getting ready to push its prodigious weight around the circuit.

The current generation ML63 AMG churns out 503 horsepower and 465 pound-feet of torque, but with the twin-turbo 5.5-liter mill bolted in, the reworked high-po ML could see at least 544 hp and close to 600 lb-ft of twist. In addition to the upgraded engine, the camo-clad mule also benefits from a more aggressive lower-front fascia, a new character line running across the side and an assortment of other revised body mods, all of which should make their way to the new model when it goes on sale early next year.
