The Hummer H2 is an icon of the Gulf War that is about to go through tough times, with troubles affecting oil prices and especially with the new environmental rules issued by governments. This year, the H2 series gets a modified 393 horsepower 6.2-litre V8, which can be run on FlexFuel E85 biofuel (85% fuel-15% ethanol, much less polluting). Still available in the H2 and H2 SUT versions, the gigantic Hummer H2 is surprisingly nimble for its size.
