Our friends at KickingTires.com have noted that Ford is doing some interesting design work with their new products, most recently seen in the new Ford Flex that will be at the Los Angeles Auto Show.
Along those same lines, Ford looks to be trying some new looks with their half-ton pickups as well.
The camouflage on this prototype is quite transparent so the new grille and chrome-outlined headlights on this XLT SuperCab are easy to identify.
The new face looks to have the same "vice-clamp" on the front crossbars as does the current-gen Super Dutys and new Ford Flex (although the Flex has a single bar). The C-clamp design feature in the F-150's grille is the most obvious example of Ford's desire to give all their vehicles (at least on the truck and SUV sides) a common face.
It's not yet known if the interior or powertrains will receive any tweaks for the 2013 model year update. As you can see, this test unit has EcoBoost badging and common tailpipes.
This is likely to be the last facelift for the F-150 before it gets totally redesigned in less than three years time.
