Re: MPG 20 or not
Last weekend we drove from the LA area to Sedona AZ and got 17.9 mpg averaging 65+ mph with the a/c on. That's for an automatic with 5000 mi., Adventure pkg, brush guard, roof bars and std tire pressure on a route with a lot of long grades.
Based on that I think I could get really close to 20mpg if I turned off the a/c, upped the tire pressure and drove with max economy in mind; maybe even more.

Driving across the desert when it's 110 with the AC off, to save gas. I wouldn't do that.

Re: MPG 20 or not
21 mpg doing 45-55 mph.
16 mpg at 65
15 mpg at 75
12-14 around town, short trips during the week.
This is with a loaded AT Luxury.
Realize that ethanol has a lot less btu/gallon than gasoline, and a 10% blend will drop your mileage 1-2 mpg.
Do not use E85 of course in a 2006. I don't know about the 2007s yet.

Re: MPG 20 or not
I got 20.1 MPG highway today at 65 MPH. I got 19.1 MPG Highway doing about 70 MPH, and this is an automatic, not stick shift. Otherwise it is about 16 MPG city. But take note that I have about 6000 miles on the vehicle, so it is pretty well broken in by now.

Re: MPG 20 or not
I get 19 - 19.5 back and forth to work very little stop and go 35 miles 1 way. I have almost 25k on the little monster and check my mpg every tank full.
