Until now there's more in interest in what will be powering the next Ford F-350 Super Duty than what it will look like. It's already been announced the problematic 6.0L Powerstroke diesel will be replaced by a new twin-turbo 6.4L diesel motor that may utilize piezo injectors to help meet more stringent emissions standards that take effect next year.
From these spy photos it's clear that Ford is growing the F-350's front end substantially to accommodate the new powerplant. One shot in particular shows next year's redesigned model parked next to the current model, which makes evident a taller hood and lower bumper along with more pronounced front fenders. As always the grille grows even larger and the new flat front appears to have vertically stacked headlights, as well.
