Wow, I am surprised that there is that much difference in MPG from the Echo to the Xb. This was an echo hatch back with power steering and running the AC for 2/3 of the trip.
We didn't get a chance to fill up the car again so this is a scangauge number and it maybe off by a couple MPG. My scangauge is usually right on for my Neon fill up but it could be off for an Echo.
Maybe the gear ratios are different for the Echo hatch and the Xb? I would assume the Echo sedan would be even more aerodynamic that the hatch as it has abit more of a tear drop shape before it has flow seperation. I have another friend with an Echo sedan that is automatic but on the highway it shouldn't matter much, I'll have to go for a ride in it with the scanguage and see what its like.
