Expedition NEW MOTORS!!!

The F-150 lumbered through a few years with the less than venerable 5.4 L V-8 but has graduated to far better motors in the last 4 years, particularly the 5.0 L V-8 and the 3.5 L Eco-Boost.  If these newer higher performing motors are good for truck duty why have the Expedition and Expedition EL not been left out of what seems to be much better truck performance with much better economy.  The 5.4 L V-8 died out of the F-150 for good reasons.  Now there are far more good reasons for it to die out of the Expedition families.
