Not sure if anyone has posted this already but this would be mine for urban enviromentTHE TUMBLER
This thing really does drive! They sent it around to all the NASCAR tracks for a pre-race show the year of the movie.
Weighing 4.5 ton (9,000 lbs) the RipSaw MS2 vehicle is sized like a HMMWV. It can carry about one ton (2,000 lbs) of payload and be controlled remotely or operated by a driver and a crewman. The vehicle uses a lightweight tubular chassis design, derived from NASCAR race cars, powered by a 6.6 liters duramax diesel engine, developing 600 hp and 1000 ft/lb of torque, providing exceptional power to weight ration for vehicles at this class. Fully weaponized and loaded, the RipSaw MS2 can accelerate from 0 to 50 mph in 5.5 seconds (!) reaching a top speed of about 60 mph. "Ripsaw is very quick and agile, it can easily outmaneuver a human" Michael Hawe told Defense Update, indicating this is not trivial for a UGV. The high power-to-weight ratio, efficient suspension and low ground pressure are providing RipSaw MS2 with exceptional maneuverability. Its center of gravity is located 70 cm (30") above, contributing to the high stability in steep gradient (50degrees) and side slope (45 degrees). High ground clearance (60cm – 24") and relatively low weight, wide tracks and the suspension's long travel maintain low ground pressure of 2.8 lbs/square inch. This attribute enables the vehicle to traverse rugged terrain at high speed, negotiate vertical obstacles up to 1.5 meter (60") high or rip through barriers like a heavy tank.The innovative mechanical clutching system that controls the hydrostatic transmission with the power, speed and simplicity of a mechanical drive system is responsible for the vehicle's rapid acceleration, maneuverability and control.The RipSaw MS2 is only 1.77 meter high, thus capable to effectively blend in the terrain, and mask itself from enemy observation. The low silhouette is also beneficial when moving forward as an advanced fire base; RipSaw-MS2 has already been tested with the 7.62mm and .50 Cal machine guns. The vehicle was also demonstrated carrying Javelin missiles, but none were fired sofar. The vehicle was weaponized by the Armys Armament Research, Development and Engineering Center (ARDEC) at Picatinny Arsenal, NJ. The kit included the installation of a remotely controlled M240 machine gun operated from a separate console installed in the control vehicle.
