GM tried to trick the Chinese into buying the Hummer, but in the end China was too smart for that. In fact, when it comes to gas mileage and efficient fuel use, the US is among the dumbest countries around. China has shown a much better record recently and their refusal to buy the Hummer is a confirmation of that.
Good riddance to the gas guzzling Hummer. The US simply cannot afford to waste fuel like that in the expensive oil years ahead.
