I had a 97 grand marquis that had no problem getting 26 mpg on the highway it had 2.73's. I also had a 93 mustang with the 5.0 and auto with 3.27 gears that would do 25 on the highway. Yes, these aren't trucks but a very modern V-8 or should not have a problem with low 20's in a truck! Even a diesel should be knocking down upper 20's by now. That is of course if they focused on mileage instead of power!
They do. The Ecodiesel makes about the same(if not more) horsepower and more torque than the diesels in 1997 and gets upper 20s mpg. While the diesels with same displacement grew in power to more than double of what they used to back then.
This goes back to what I stated earlier. As technology allows a big liter 6.6/6.7L diesels to gain more energy out of a drop of fuel, its power will increase along with a moderate increase in efficiency. If you want to keep the power the same while having a greater increase in fuel economy, then you would have to go to a smaller displacement engine as fuel efficiency technology improves(i.e. the more energy you are able to get out of a drop of fuel).
I see your point. I'm just thinking of what hey could do with the current motors!
