ellena formelent’s spies have bagged new photos of the upcoming 2012 Mercedes-Benz ML 63 AMG testing in Germany. The most powerful member of the new M-Class family will compete against BMW’s X5 M, which packs a twin-turbocharged 4.4-liter V8 engine pumping out 555HP and 680Nm or 501 lb-ft of peak torque.
The current ML 63 AMG is powered by a naturally aspirated 6.2-liter V8 engine delivering -in U.S. spec- 503HP at 6,800 rpm and a peak torque of 465 lb-ft at 5,200 rpm. Even thought the 63 badge will remain, as with other new AMG models, the flagship version of the next ML will ditch the 6.2-liter lump for the firm’s newly developed 5.5-liter twin-turbocharged V8 boasting direct-injection technology.
