The altitude and the wind make a HUDGE difference. Seems like what will get 15-16 on long island, NY will get 11-12 in colorado.

FYI:
On long island, NY (Sea level) I have gotten my ford expedition (4.6L) to 19.8 on the highway with the mirrors folded in, the tires over inflated by 10lbs, and the roof rack bars removed. You wouldnt beleave how much of a difference folding those dam big ass mirrors in makes! Safety note, only do this on a deserted highway (As i did one late night in NJ).

I need a second car. I might have to pick up a jetta diesel, drove on the other day....nice power. My buddy gets 45 real world mpg driving normally!!! Towing a 2 place snowmobile trailer with 2 snowmobiles on it in the hills of upstate NY he still gets 35mpg!!! AMAZING. Gay I know, but dont worry my H2 aint going anywhere (At least until i can get a duramax h2)!

MPG is so up to the manufacturer. The euro diesel jetta has a bigger motor, more power and it gets 81mpg. I guess its all a matter of how much time the manufacturer will invest in getting the car/truck efficent.
