The Hummer H3 is presented as the automaker's compact vehicle, since it was developed around the platform and main elements taken from GM's Colorado and Canyon trucks. The 239 horsepower 3.7-litre five-cylinder engine is reserved for the basic H3 and H3T models, while the 300 horsepower 5.3-litre V8 powers the Alpha versions. Five-speed manual or four-speed automatic transmissions complete the picture. In the hope of being a little trendier, the 2009 H3s are equipped with multimedia connections.
