Fuel economy is not really going up per say.....that may also be because engineers can only go so far reducing aerodynamics, friction etc.

Marty, I would argue fuel economy on these trucks has gone up significantly, especially considering the increase in power they have.
MPG took a hit when new EPA regulations first came out, but the new trucks seem to report better MPG than any prior year diesels, and now have nearly twice the torque that trucks did just 10-15 years ago.
I think there is still room for improvement, but when a 2017 RAM has 385/900 gets as good as, or even better MPG than my old 2003 RAM with 305/555, I don't think you can really complain.
