About Hummer H3

Inheriting the spirit of tough Hummer, Hummer H3 was produced by an American multinational corporation General Motors Company but marketed by AM General's brand Hummer from April 2005 to May 2010 as a Sport Utility Vehicle (SUV)/off-road vehicle. Originally introduced as the smallest among the Hummer models, H3 was built based on the GMT355 along with the Chevrolet Colorado and GMC Canyon compact pickup trucks. Due to the demise of the Hummer brand, the last H3 rolled off the assembly line on May 24, 2010, although before that it did well in safety tests conducted by IIHS and NHTSA and Motorsports.
Hummer H3 made its debut in May 2005 for the 2006 model year with two body styles. It was available as a traditional 5-door mid-size SUV and a mid-size 5-door pickup known as the H3T, which came with several trim levels including standard H3T, H3T Adventure, H3T Luxury and H3T Alpha. Boasting a maximum towing capability of 3,000 lb, Hummer H3 was powered by 3.5 L inline-five rated at 220 horsepower and 225 pound-feet of torque, 3.7 L inline-five producing 242 hp and 242 lb-ft of torque and 5.3 L V8 making 300 hp and 320 pound-feet of torque. And these engines sent power through either a 4-speed automatic or a 5-speed manual transmission to four wheels.
