The first week I had the car it went from LA to Sacramento for Thanksgiving. One tank up, one tank back. No EcoPro and mostly was going 75-80MPH. If I remember correctly I was just above 31MPG outbound and 29MPG inbound, the difference being about 1,000 feet of elevation change coming back. Again that is brand new with very little milage on it. I did keep the revs down and tried to vary my speed a bit for break in purposes so the transmission did not get to settle down much.

That was all computer calculated so if you don't believe the CPU you can discount! I just found my photo and it say 947 miles, 29.7MPG, 62.2MPH.

The car can do it. I can't tell you why your car can not but I'd start to wonder if something was screwy in my drive train.
