I watched these two The Fast Lane truck videos on the upcoming 2020 Super Duty's. They are about 12-minutes each.
The first deals solely with the new 7.3l pushrod V8 gas engine, and the second covers pretty much the whole truck from the ground up.
Of course Ford hasn't released specs and pricing yet; but it will be interesting to see how the new 7.3l engine does in the power, torque and fuel economy department.
