Hummer H3

The Hummer H3 was a SUV/Sport Utility 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 among 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. The H3 was launched with a 3.5 liter straight-5 cylinder L52 engine that produced 220 hp and 225 lbf·ft of torque and... was mated to a standard five-speed manual transmission or an optional Hydra-Matic 4L60-E four-speed automatic transmission. In 2007 this engine was replaced by 3.7 liter LLR that produced 242 hp and 242 lbf·ft of torque, figures that were revised in 2009 to 239 hp and 241 lbf·ft . Under revised EPA testing standards when equipped with either transmission this straight-5 engine achieved 14 mpg-US in the city and 18 mpg-US on the highway with a combined average of 15 mpg-US .
