Hi David,
I can't explain the CR estimate of 25mpg, but I can tell you that the information is false. I will admit, on my first tank of gas, I only hit 26mpg - and I was a little disappointed. But as many here will tell you, it takes a while for the engine to break in and to learn how to drive more efficiently (they call it "driving with the load"). I now have had my car for little over a month and I am currently averaging 35mpg during my 30min trips to work driving mostly hwy @ 70mph. I just got back from driving a 400 mile trip where I got up to 39mpg - I just couldn't break 40 though

But it still beats 25mpg - and I am sure I will reach 40mpg or more with a little more patience on my part - I like using the V-6 to blow by all the Hummers...
You will see in the Compare Section, that most HAH are averaging 30mpg. But I believe this number is a little low since some of us are still new to the HAH experience (statistically speaking, you would also want a larger sample size

). You will find a lot of good information on this site with a lot of helpful people who are more experienced and can provide better information than I. Good luck!
