What surprised me is that my new truck gets 16mpg around town and 15.5 running 80 down the highway in a rainstorm on cruise.
I'm thrilled with the 16, but not so much with the 15.5.
All according to the lie-o-meter (though I am keeping logs and they match.)
Have just about 800miles on her now.
Little science here: there is a big difference in economy between 75mph and 80mph (I know this is harped on in this forum) .
Power consumed due to drag is a cubic function (with respect to velocity):
What that means is for each mph faster, the power required (and fuel burned) is exponentially greater (to the power of 3)
Seldom do I actually get to use my engineering education!
