As is well known by now, Ford and Navistar have parted ways and the Blue Oval is developing diesel engines in-house to replace the PowerStroke lumps still being used. Slated to appear in Ford's trucks by 2011, the new oil burner code-named Scorpion is a 6.7-liter V8 with a host of innovations, some of them seemingly borrowed from cross-town rival GM.
But the first thing you'll notice is that mammoth radiator. PickupTrucks.com estimates that the cooler up front is up to 20-percent larger than the one on the 2008 Super Duty, and that one had already been enlarged by 33-percent over its forebear. The extra cooling could be needed for "extreme towing applications", and if there's one truck that's an extreme tower, it's the F-Series Super Duty.

The Scorpion diesel's innards will be enhanced with reversed intake and exhaust flow, something found on GM's Duramax diesel, and lighter aluminum cylinder heads. Nor will the Scorpion sacrifice mpg for its extra oomph: gains of 40 hp and 70 lb-ft will come with three more miles-per-gallon thanks in part to the truck's new 6-speed tranny that's debut as we speak on the new F-150.

      This is going to be a kick-ass motor. Ford really knows how to build a capable and reliable motor for a truck
        • 6 Years Ago
        Alright then, how about the all-Ford plug spitting 5.4?

        • 6 Years Ago
        @Sean: Unless I am mistaken, the 6.0 and 6.4 were "Cornbinders" (Navistar), not Ford-designed or Ford-built.
        • 6 Years Ago
        LOL, except for the 6.0 and 6.4L Diesels.... Disasters, both of them.
      • 6 Years Ago
      Maybe so, Paul. But a 6.4 running 350bhp would have brilliant low-end torque, right? And in a big truck, that'll mean good mpg.
      • 6 Years Ago
      Ford, since you are at the diesel thing, why not developing some small ones to put on cars?? Or better, bring them from europe.
      • 6 Years Ago
      Ford has the smaller 4.4L diesel coming out with ~325hp, sounds like exactly what you're looking for.
      • 6 Years Ago
      And don't mute it Ford. Diesels sound B.A.
      • 6 Years Ago
      Almost 400hp and over 700lb-ft of torque, and a whole 3mpg more. How about keeping it "only" 350hp and working on making them get a little more mileage. This is what will kill diesels is the manufacturers trying to make them fast and powerful and not focusing on their efficiency enough. Yes trucks are meant to tow and you need a powerful, but you can't say that a '08 truck is worthless with only 350hp when that's clearly not the case. I just wonder what company will finally man up and stop the horsepower wars with diesels and bring out a 1-ton truck that gets 30mpg. That will be something to really talk about!

      FWIW the big radiator is to make up for the efficiency lost due the heavy exhaust gas recirc coolingt needed to pass 010 emissions.

        Nice Post. I was wondering why. Thanks
