GM (General Motors) does not build many cars like the Hummer H3: a 4-door SUV (GMT345) / 4-door pickup truck (GMT745) with 3.5 , built from 2005 to 2010 in the decade of stability control, dual-clutch gearboxes and the first serious hybrids.
The background
The Hummer H3 is an off-road vehicle that was produced by General Motors and marketed by Hummer from 2005 to 2010. The smallest model of the Hummer lineup, it was offered as a 5-door SUV or a 4-door pickup truck known as the H3T.
Unlike the larger H1 and H2 models, the H3 was not developed by AM General. It was introduced for the 2006 model year, based on a modified GMT355 that underpinned the Chevrolet Colorado/GMC Canyon compact pickup trucks that were also built at GM's Shreveport Operations in Shreveport, Louisiana, and the Port Elizabeth plant in South Africa. While mechanically related to the Colorado and Canyon, GM claims they share only 10% of their components, with the chassis modified and reinforced for heavy off-road duties.
The engineering
Under the skin sits 3.5 other versions carried different engines, listed in the specification table below. Kerb weight is 4600 -. The gearbox is a 5-speed Aisin AR5 manual / 4-speed 4L60-E automatic. The layout matters: drive goes to all four wheels, which is what lets the power be used on a wet road. The wheelbase is H3: 111.9 in / H3T: 134.2 in. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Where it sits
Where it sits in GM (General Motors)'s history is not in doubt: the Hummer H2 came before it; the GMC Hummer EV followed it; it was built at Shreveport, Louisiana. On a showroom list of its day it stood against the Audi Q7, the Bugatti Veyron, the Aston Martin Vantage. Its GM (General Motors) stablemates include the 1955 Chevrolet and the 1957 Chevrolet.
