I only did it as an experiment though because it's not realistic to drive like that all the time.
I did live the power though of the F150.

No doubt it takes gas to make power regardless how you do it. However, with the smaller displacement you can just set the cruise control at 70 and get 23-24 MPG. Hit a hill though and it will use the turbos and more gas. A slightly larger engine like a 3.8 or 4.0 would help there, but a lighter vehichle would too. I don't think either will happen.
I personally think the turbo V6 works better in a heavy vehicle, up to a limit. From the torque and hp values we are seeing for the LF3 it really sounds to me that it is tuned for a SUV or truck and not a car. Only time will tell.
