The following historical data of the Hummer H3, manufactured by Hummer, were retrieved from many sources.
The Hummer H3 was a truck from General Motors’ Hummer division introduced in 2005 based on the GMT355 underpinning the Chevrolet Colorado and GMC Canyon compact pickup trucks. Produced at GM’s Shreveport, Louisiana factory and the Port Elizabeth plant in South Africa, the H3 was the smallest of the Hummer models, and the first to be built by GM. It was available either as a traditional midsize SUV or as a midsize pickup known as the H3T.
In 2007 GM South Africa launched their first Hummer production facility in Port Elizabeth, this move introduced the Hummer brand to the South African market and also somewhat lightened the load of the Shreveport factory in Louisiana. The plant manufactures only the Hummer H3, and builds for the South African market as well as the markets of Asia and Europe. This plant also manufactured a right hand drive version for the Australian market between 2007 and 2009. Throughout Australia, Hummer was distributed by GM Holden dealerships.
The H3 was launched with a 3.5L straight-5 cylinder L52 engine, and was mated to a standard 5-speed manual transmission or an optional Hydra-Matic 4L60-E 4-speed automatic transmission. In 2007 this engine was replaced by 3.7L LLR engine. The H3 and H3T are being discontinued after the 2010 model year as GM is winding down the entire Hummer brand.
