You can’t keep a good solider down.

AM General has unwrapped the latest take on its venerable Humvee: the Ground Mobility Vehicle (GMV 1.1.) Slimmer and trimmer that the original, it has been fully reengineered to meet the requirements set by the Pentagon for the next generation of vehicles it is currently seeking to support U.S. Special Forces operations.

Powered by a six-cylinder, 3.2 liter turbocharged diesel engine rated at 300 horsepower and 500 lb-ft of torque, the GMV 1.1 has a top speed of 80 mph and can climb a 40 percent grade and traverse a side slope just as steep. It will accommodate six articulated weapons mounts including a turret on the top, and can be outfitted to ford water crossings up to five feet deep. Per Defense Department specifications, it has been designed to fit inside a Chinook helicopter for rapid deployment.
