Spy Shots: Ford Super-Duty's new 6.7L Scorpion diesel
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

LOL, except for the 6.0 and 6.4L Diesels.... Disasters, both of them.

@Sean: Unless I am mistaken, the 6.0 and 6.4 were "Cornbinders" (Navistar), not Ford-designed or Ford-built.

Alright then, how about the all-Ford plug spitting 5.4?

Yeah, my good old 460 still runs great.

I find it funny that all of the 6.0 PSD that were used in Navistar applications did NOT have the problems that they did in the Ford applications. And yet, Ford blames Navistar for their ineptness.
It reminds me of the 1996-1999 Taurus SHO V8. The Yamaha designed parts were fine...it was the Ford parts that failed.

The Navistar versions (VT365) also had problems and has in fact been discontinued (except in some military apps which have a different injection system to allow them to run on jet fuel).

Ford, since you are at the diesel thing, why not developing some small ones to put on cars?? Or better, bring them from europe.

And don't mute it Ford. Diesels sound B.A.

390hp and 720ft-lbs tq from the factory in a pickup? Wow! I want a short bed regular cab version with a six-speed manual to run at the track. Then, on the way home, just for fun, I can pull a house off it's foundation.

As much power as that is, wrapping 3.5 tons of Superduty around it makes for a pretty sluggish vehicle by commuter standards.
Paul P. 1:39AM (10/09/2008)
With all that torque I doubt it will feel sluggish, even if it weighs 5700+lbs.
Dan 11:44AM (10/09/2008)
The current edition with 650 ft-lb is a 0-60 in 10 seconds, 1/4 in the upper 17s rocket ship.
That's impressive for a vehicle that heavy - and 5700lbs is about 1000 lbs short of the real weight - but it's notably slower than almost any passenger vehicle you can name.
jpvbs 5:49PM (10/09/2008)
actually, a crew cab 4x4 (8000 lbs) 6.4 should be good for low 16s, maybe high 15s in good air - bone stock. A dually pulling a trailer might run high 17s.
and FWIW, stock GM duramaxs can get into the 14s.

Pickuptrucks.com got a 9.6 0-60 and 18.0 quarter out of the 08 6.4 F-350 DRW they tested.
CR got a 9.8 0-60 and 17.6 quarter out of an 08 F-250 SRW, also with the 6.4.

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!

Ford has the smaller 4.4L diesel coming out with ~325hp, sounds like exactly what you're looking for.

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.

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
