The 2010 Hummer H2 SUV and H2 SUT are powered by a 6.2L all-aluminum small-block V-8 engine rated at 393 horsepower and paired with a Hydra-Matic 6L80 six-speed automatic transmission.

Performance-optimizing engine technologies, such as variable valve timing, and the six-speed’s wide gear ratios, including a “tall” overdrive gear, optimize the powertrain’s efficiency.

The H2 lineup’s luxury-appointed interior features a detailed instrument panel, three seating rows, a rear climate control system, a rear-seat overhead DVD entertainment system and a family of premium radios. The seats have a chiseled appearance and offer excellent comfort.

The pulling power of the H2 comes from its 6.2L V-8 engine that has 415 lb.-ft. of torque. A 3.73 axle ratio and features such as regulated voltage control that charges electrical components only when necessary help maximize the H2’s efficiency, while the powertrain enables a towing capacity of 8,200 pounds.

The H2’s foundation is a fully welded, ladder-type frame that features a modular, three-piece design incorporating a number of hydroformed components. This design delivers outstanding strength, stiffness and dimensional accuracy.

Short overhangs allow radical approach and departure angles, as well as exceptional ground clearance for minimal impact on trails. Standard 17-inch wheels, heavy-duty independent front suspension and a five-link rear suspension provide superior handling, carrying and towing capability.
