Michigan weather usually is never good this time of year, but one positive thing for our spy shooters is that the windy weather can blow the covers right off any prototypes that might be running around the bad weather. That's what happened with this Ford F-250 prototype.
It appears the Super Duty will get a modest update to the front fascia with a new grille, grille inserts and trim. Although it doesn't show here, this truck's tailgate was camouflaged, too.
We suspect the Super Duty may be playing with some aero changes in the rear, and possibly open/close louvres in the grille. We've heard that Cadillac and certain Chrysler vehicles have been testing at both ends with electronically controlled shutters and wind deflectors to help improve airflow and engine efficiency.
We're guessing you'll see the official debut of this new Super Duty at the 2012 State Fair of Texas.
