Although none of the Hummer models are really all that worse than any other body-on-frame SUV powered by a large engine, the ex-military marque is considered by many to be the anti-green brand. If that's how you feel, you'll likely be glad to hear that Hummer models are languishing on dealer lots all over the country. Hummer spokeswoman Joanne Krell suggests that the downturn in sales is directly related to the upturn in fuel prices. That makes sense, now doesn't it? Maybe not... Acura is the only brand that has seen similar drops in new registrations with nary a V8 engine in sight. All of this raises a few questions: Is the Hummer brand is just plain falling out of favor? If so, would flex-fuel engine options help their cause?
