About Hummer H3T

Hummer H3T is a mid-size pickup truck manufactured by General Motors but marked by Hummer during the 2009 and 2010 model years. The first Hummer H3T was introduced in 2008. It was built at a highly modified GMT355 underpinning the Chevrolet Colorado and GMC Canyon compact pickup trucks, so Hummer H3T was more or less influenced by their design ideas.
The Hummer H3T was designed based on a regular cab two-door concept truck introduced in 2003 and then released to the public at the 2004 Los Angeles Auto Show. And then the production version Hummer H3T was a 4-door crew-cab mid-size pickup truck and was unveiled at the 2008 Chicago Auto Show. It was offered in standard H3T, H3T Adventure, H3T Luxury, and H3T Alpha (with cloth or leather trim) trim levels. And H3T featured a 5-foot bed with built-in storage boxes. Hummer H3T had been always powered by a 5.3 L LH8 V8 engine that could produce 300 hp and 320 pound-feet of torque. And this engine was fitted along with a standard 5-speed automatic transmission or an optional Hydra-Matic 4L60-E 4-speed automatic transmission.
