Last week we finally got official details on the 2013 Mercedes-Benz G63 AMG, despite having known almost everything in advance. Now a series of promotional videos are giving a detailed look at the SUV inside, out and in action.

Earlier this month we reported details of an upcoming AMG hot-rod version of the iconic G-Class SUV. Now, Mercedes‘ AMG division has given us official information on the thing, essentially confirming much of what we already knew.

The G63 AMG sports a 5.5-liter twin-turbo (or as Mercedes calls it Bi-Turbo) V8 cranking out 544 horsepower and 560 lb-ft of torque, teamed with the AMG Speed-Shift Plus seven-speed automatic transmission. If that isn’t enough, there’s always the option of stepping up to the even more powerful G65, which sports a 6.0-liter Bi-Turbo V12, rated at 612 hp and a monstrous 737 lb-ft of torque.

Although it hasn’t been officially given the green light, there’s every indication that a hot rod version of the recently introduced ‘baby’ Range Rover could be on its way.

While some automakers appear intent on taking fun out of the equation, Chrysler group seems is doing the opposite. With a raft of performance vehicles on offer through its Street and Racing Technology (SRT) brand, the company caters to those that still like a good ol’ fashioned dose of American pavement melting horsepower.

Back in March, at the Geneva Auto Show, 2010 Formula One World Champion Sebastian Vettel and Infiniti‘s Chief Creative Officer, Shiro Nakamura got chatting.
