The Hummer H2 is only the second model sold by the Hummer marque, a division of General Motors. It shares its platform with the Chevrolet Tahoe and the GMC Yukon. The front of the Hummer uses a modified GM 2500 Series utility frame. The mid-section is completely new, while the rear section is from a modified GM 1500-Series frame upgraded to accommodate the 8,600 pound gross vehicle weight.
The engine found in the Hummer H2 from 2003 through 2005 was a six-liter V8 unit capable of producing 325 horsepower. In 2008, a 6.2-liter unit rated at 393 horsepower can be found under the bonnet.By Daniel Vaughan | Jan 2008
