I can't report on mileage since I don't have one but I always figured that with a Hemi you could get just as good if not better mileage than the 3.8 because you could lug it around at lower revs with the extra torque.

I don't know about the VVT, but my 5.7L from an '08 Grand Cherokee is netting me about 12 MPGs. This is with a lifted, steel-bumpered Rubicon Unlimited with 35" Nitto Mud Grapplers.
My mileage took about a .5 to 1 MPG drop after the swap. I believe this is due to the added weight of the Hemi and the new transmision. And the liberal use of the skinny pedal isn't helping in that department either............
But, the GPM (grins per mile) is WAAAAAY up.

In regards to range its still important. With my last jeep I hated that I had to stop for gas every 200 miles or load up on gas cans. If I ever do get a Hemi I sure hope its as good or better then the 3.8 due to this fact alone.

Seriously I have the stock motor in my 2 door, and wish I could go more than 200 on a tank as well. I was thinking about the gen right extra tank, but that is a lot of rear end weight.

Sarcasm never works on this forum. I was kidding. I live 15 min from the border, and range is very important to me as well. Like I said, there is a fuel tank that fit in place of a stock muffler. An extra 20 gal will fix the mpg difference.
