Here's the true story... When we went from a 5.3 Yukon SLT to our 6.0 Denali, we gained right at a mile and a half per gallon. Doesn't figure does it. (not a question) It does to me, particularly how hard we flog the 3.5 with the heavy Hummer. The 5.3 won't be working as hard. On the freeway, it's a matter of moving the square mass through the wind. Our Denali gets 16mpg. Y'know what my H3's getting since I put the BFG ATs on it? 16mpg. So it can't be that different with the 5.3 in the H3.
I'll let you know how it works out.
I'm pretty curious about two things though, the front and rear end (will they upgrade them to put up with the increased torque of the V8) and the Adventure package (will it still come with the 4:1 tcase and 4.56 gears)
By the way, it will be called the Alpha according to the documents he showed me. Booyah!
