I've been trying to quantify the Current F-150's drag coefficient.
In 2015, Ford added air curtains to the F-150, and although a drag reduction was claimed by Ford, the actual delta-Cd was never provided.
In a 2015, GREEN CAR REPORTS article about the new F-150, online, Stephen Edelstein wrote that, the Ford representative said,' The most direct way to deal with this drag would be to enclose the wheels in skirts.'
Again, no specific data, either way.
