Not Ranked
I have a 2010 TDI Jetta (which is one of, if not the most advanced diesel motor today) and I am getting low 40 to low 50 mpg. I don't see how you are going to get larger vehicles like trucks close to 60 MPG. My Duramax is only getting high teens to low 20 MPG. Hard to push that much weight with good fuel economy.
