Should be something interesting, but I do not see a major face lift. Most likely a different power plant.
"Delayed due to Ford's financial constraints, the heavy-duty workhorse truck range is ultimately destined to receive major changes for 2007. This Crew Cab longbed 1-ton version sports a single rear wheel, and looks to offer a slightly larger cab area. Word around the office says this vehicle is being tested with a new, smaller V-6 4.5-liter turbodiesel sourced from International, promising improved fuel economy."
"The heavy-duty workhorse truck range will be redesigned. The 6.0L diesel engine to be replaced by a more powerful 6.4L diesel."
They are being tested here in the Los Angeles area. The grille and bumpers are covered, but the rest of the exterior looks about the same as it does now. Under the hood is supposed to be this new International 6.4L, which is rumored to have a twin turbo setup (though it looks like only the compressor side is twinned, it only has one exhaust turbine) and common-rail fuel injection like the Duramax and late model Cummins. The interior is new, and the chassis is new as well. Supposedly the frame is now completely boxed, like the new Ram HD's.
Is it possible to see 2 diesel motors offered? In addition to the 6.4 I would like to see the 4.5 (or 4.8) make available as an option. Also a 6 speed auto tranny. Along with common rail injection and TT if there were some way to get rid of the EGR I think we would be in business.
