6.7L Power Stroke Engine and DrivetrainDiscussion of the 6.7L Power Stroke diesel engine and drivetrain in the 2011-Up Super Duty trucks. No gas engine discussion allowed except on transmissions and drivetrain that pertain to all models. Please confine discussion of topics in this forum to those items that are specific to the 6.7L Power Stroke engine.
Heres the info on the chev. from the detroit autoshow...
For starters, new Silverado HD models sit on new frames and come with an optional all-new 6.6-liter Duramax V8 and Allison 1000 six-speed transmission. The truck’s base tow rating is now 16,000 lbs, while a 3500 crew cab/long box can pull up to 20,000 lbs. For the record, that’s 2,400 lbs more than the RAM 3500 and 1,200 lbs more than the 2010 F-350 – although no 2011 F-350 stats are available. Maximum payload is now 6,335 lbs, well above both the Ford and Dodge, although (again) Ford claims segment-best payload… but that was before the new Silverado HD was unveiled

My 2006 6.0 liter (bone stock and not run hard), lost it's Garrett turbo at 50K miles. That does not sit well with me.
Bring on the Honeywell in my new 2011!
Same thing happened to my son,in his case one of the pins the turbo vane moves on broke off and locked the fins in a fixed setting,his is a bone stock 2004 that ford just spent $5000.00 on 6 months ago before the 5 years was upnow with the turbo gone and past the 5 year part of the warranteeit was on him!!!!, $1400.00 later............meanwhile my 2002 7.3 with a programer set @ 60 HP,tow,has never been worked on.

Im just curious, why do the chassis cabs have a lower HP/TQ rating? I also hear they are putting different turbos on them ,why is that?
The all-new 2-valve SOHC 6.2-liter gasoline V-8 is rated at 385 horsepower (at 5,500 rpm) and 405 pounds-feet of torque (at 4,500 rpm), and the all-new 4-valve OHV 6.7-liter Power Stroke V-8 turbodiesel is rated at 390 hp (at 2,800 rpm) and an earth-shaking 735 pounds-feet (at 1,600 rpm) in the F-250, F-350 and F-450 pickups. The F-450 and up chassis cabs are rated at 300 hp and 660 pounds-feet.
Let's put these powerful numbers in perspective.
For the gassers, the outgoing 2010 Super Duty's standard 5.4-liter gas V-8 is rated at 300 hp and 365 pounds-feet, and the optional 6.8-liter V-10 is rated at 362 hp and 457 pounds-feet. So the new 6.2-liter V-8 has more horsepower than either of the old engines and just misses splitting the difference in torque between the 5.4-liter and 6.8-liter, with two fewer cylinders than the massive 6.8-liter.
We can also compare the 6.2-liter V-8 in the Super Duty against its application in the 2010 Ford F-150 SVT Raptor. The 6.2-liter V-8 in the Raptor is rated at a larger 411 hp and 434 pounds-feet.
The power numbers are larger in the light-duty pickup for two reasons, according to Chris Brewer, Super Duty chief engineer. "The main reason is that when the truck goes over 8,500 pounds [gross vehicle weight rating], the SAE [horsepower and torque] rating method changes," Brewer said. "We can't get the same horsepower and torque out of it [like we can in the F-150].”
The 6.2-liter V-8 in the Super Duty also uses a different camshaft from the light-duty version, which, some may recall, is the same approach Ford uses to make 500 hp in the FR Raptor XT version of the 6.2-liter V-8.
Before we compare the old and new diesel power ratings, you may be wondering why there are two sets of power figures for the 6.7-liter diesel. Again, gross vehicle weight rating plays a role.
The Environmental Protection Agency requires different emissions testing procedures depending on the gross vehicle weight rating, which leads to different power ratings. So-called "heavy-duty light trucks" below 14,000 pounds GVWR are tested using a chassis dynamometer; medium-duty vehicles whose GVWR is 14,000 pounds or greater are tested using an engine dyno.
Comparing the oil burners, the old chassis-certified 6.4-liter Power Stroke diesel V-8 is rated at 350 hp and 650 pounds-feet, so we're seeing a substantial jump in power by 40 horses and 85 pounds-feet from Ford's in-house designed and built 6.7-liter V-8. The dyno-certified 6.4-liter is rated at 325 hp and 600 pounds-feet, or 25 hp more and 60 pounds-feet less than the 6.7-liter.
"We're real pleased about the numbers for the new gas and diesel engines," Brewer said. "It's a big win for customers and us."
With all of the power and pulling improvements, Ford hasn't left fuel economy out of the equation. "For the pickups, we'll see an 18 percent improvement in fuel economy and 25 percent in the chassis cabs," Brewer said.

SHORT LIVED..............................
2011 Super Duty's new towing and hauling capabilities. Last week, GM announced its new 2011 Chevrolet Silverado 2500 and 3500 pickups would have best-in-class towing and hauling, pending the release of Ford's numbers. Ford is now claiming those numbers and bumping them significantly higher over the 2010 Super Duty.
The F-250 and F-350 single rear-wheel trucks can tow up to 14,000 pounds conventionally and haul 4,050 pounds and 4,500 pounds, respectively. The F-350 dual rear wheel is rated to pull 16,000 pounds conventionally and up to 21,600 pounds using a fifth-wheel hitch. It can haul payloads up to 6,520 pounds.
Maximum towing requires a standard 3.73 or optional 4.10 rear axle. For those interested in prioritizing fuel economy or looks over towing, the Super Duty can be ordered with 20-inch wheel s and a 3.55 final drive ratio or a tall 3.31 ring and pinion, which was introduced as an option in 2010.

1.) What is the MPG city/Highway?
2.) Reliability?!(/longevity), I will not get rid of my 7.3 until I see the new motor has the same reliability/longevity. (or until I cant find the block or parts to rebuild the old gal)

Ford raised their tow ratings and hp/tq numbers but forgot about stopping. They have the same size brakes and don't offer an exhaust brake like GM and Dodge.

All the technical descriptions of the 6.7 mention that the turbo functions as an exhaust brake. Most of the tranny technical descriptions also mention this. There is not a separate exhaust brake , nor is there an exhaust brake button, from what I read the tow haul mode uses the tranny and turbo to control vehicle speed and increase stopping capability. I also seem to remember that the cruise uses the tranny and turbo to prevent exceeding the set speed but would have to find that statement again.

Well, one advantage that the Dmax definitely has is its DPF strategy. They are the only one of the big three who will not have to deal with the fuel dilution problem. That by itself is a strong argument for an expected longevity advantage.

I don't understand what you are saying."fuel dilution problem" Do you mean using Urea?
Ford&GM use Urea in all diesel trucks, Dodge only uses Urea in cab an chassis.
As for longevity, how is GM better?
