The Hummer H3 is an off-road vehicle that was produced in the 2002 to 2006 period by General Motors. Hummer H3 is the smallest of the Hummer line up vehicles and had a five-door SUV and four-door pickup truck variation. The four-door pickup truck traded under the name H3T. Unlike the previous Hummer vehicles, the H3 was not manufactured by AM General and was introduced for the 2006 year model. The Hummer H3 is based on the GMT355 and copied the Chevrolet Colorado and GMC compact design. While the resemblance of the Colorado pickup truck and the Hummer H3 is evident, the manufacturer claims they only share 10% of the components.
