While I was walking around the Chicago Auto Show today, it occurred to me just how many large trucks, SUVs and gigantic vehicles were in attendance. So, I decided to take pictures of them, and if a fuel mileage estimate were there, I took a shot of that as well. I'm finding it kinda hard to choose which one is really the least green. There were the three International trucks, which make much more sense as semi trucks than daily-drivers. Of course, no non-green list would be complete without mentioning the Hummers. There was the SRT8 Grand Cherokee, which took the "Worst Listed Fuel Economy" award. But, I really think that the six-door Ford Super Duty truck that was lifted to the moon wins the award. I just can't see any real purpose for the vehicle to exist. Large trucks, such as the Super Duty trucks, are necessary in today's society, but not this one. I didn't ignore the cars either, as I shot a four-door Maserati and the new four-door Bentley with it's twelve cylinder engine. Enjoy our gallery, and let us know what you think.
