They are currently testing a 2014 Ram 1500 3.0L EcoDiesel and a 2014 Ram 2500 6.7L Cummins (370/800 version).
According to their facebook posts, they are averaging 27.9 mpg in the 1500 and over 20 mpg in the 2500 at 75 mph, and have climbed over 5000 feet in elevation during their highway cruise so far. They said they "Aren't trying to maximize mpg, but give you a real world number at 75".
Sound promising.
My wife's Fusion doesn't average 28 mpg no way a truck will average that. Unless you are averaging 28 mpg 100% highway without traffic.
