New 2011 superduty does 34mpg (hypermiled around a test track).. It averaged 29mpg.
Yes urea is expensive.. Yes..
But less fuel is now being burned to provide good emissions. Less in-cylinder controls and a more free turbo match = more mpg and more powah...
But... You know what.. ZOMG it is throttle by wire... We're all going to die because of a lack of mechanical connection..
You're mistaken, since it's american and not japanese we're going to die of fit and finish papercuts, not a spectacular runaway crash...

Luckily I can spot Internet sarcasm from 2 miles away.
Trying to explain to people that diesels have been drive by wire since...well before I was born I think.... is always met with some resistance.
Funny side note: On a business trip recently I got to drink a beer with the engineer who did the calibration on the electronic pedal controls for the Detroit Diesel Series 60, back in the 80's. He claims triple redundancy on the pedal assembly.

I lol'd.
But really, the point of my posting this is that the new diesels will now, from the factory, produce 25-30mpg results. This is due to the fact that we now don't have to burn fuel now to do it.

Hmmm, 2011 truck is hypermiled to get in the 30's, pretty good. My 93 Cummins with 365,000 miles got 23-25 on the open road, not hypermiled and driven in traffic. I'd still get 20-22 loaded with double axle trailer loaded with a car and spares. I'd say good job, not great job.

your truck donsen't have emissions. Your truck also doesn't have 700lb-ft of torque stock. I think it's a big accomplishment from a stock truck.
One of the things that was interesting was that the 17" wheel truck could get the higer mpg. The 20" wheel truck couldn't break 26mpg.
I agree igny, this is some fantastic results! Clean diesels with that much grunt and still whooping butt on mileage is pretty extraordinary engineering. I still want to know what possessed an engineer to pee in the thing...

I know. Now, bring me this, with either the 2.5 or 3.0 engine.

+1.
Which is the most important part.

+1. Just make it a 4.0 engine. 200hp and 30 mpg in a Ford Ranger would be a great achievement.
I admit, it's impressive, but hypermiling is so stinkin far from anything that you'd do in traffic. What I see is this. You have a brand new truck, driven on a controlled course by a specific set of rules with one intent; to get the best mileage possible. I was driving a truck that has already driven the equivalent of a trip to the moon and most of the way back, on public roads with traffic that is not intent on letting you eek out the best mileage, I had about 7,000 lbs behind me and my route had hills, traffic lights and such. I could get in the low to mid 20's without even trying. They bested that by 30% with no load to speak of and the best possible conditions. Ok.
I'm not knocking the accomplishment, I'm glad they can prove just how efficient a diesel is. I just think "huh, I bet I could get that same ecomony out of a 18 year old truck with a third of a million miles on it if I tried. Oh, and my engine still has 1/2 a million miles left to run.

My '04 Duramax does have emissions, 310HP & 600+ lb/ft of torque and I get 19/23 in stock tune on auto diesel with no special considerations for how I drive it. I imagine with additives, a programmer and a few mods I could do a little better too (like removing the emissions).

the 2.5 and 3.0 I think of are diesels. There is no 4.0 diesel, it's not needed. The 2.5 turns out like 141 hp and 240lb-ft of torque and the 3.0 does 156 hp and 280 ft-lb.
Here's some pictures of one up close. They are NICE trucks. http://picasaweb.google.com/msjunglelady/FordRangerTurboDiesel2008?fgl=true&pli=1#

Read the article. The one dude drove one from Arizona to the test site (1900 miles) and got 28mpg. Real world. Sorry man, but there is no way your duramax would do that stock.

The best comparrison I have seen is an old diesel power project. They took a 2wd 7.3 superduty and got 26mpg out of it consistently(non hypermiled). It required aero body mods, a 2nd overdrive unit after the trans, 3.08 gears, and some fuel additive. These new guys can do that out of the box with way more torque.
edit: The biggest improvement is the fact that the current crop of diesel rigs on the market have a very hard time hitting 20. The 6.4 ford and 6.7 cummins are, despite what you read on the interwebs, 14-16mpg machines stock.
Just wonder how long it takes to make up for the diesel surcharge,

Jokes on you! There's not really a "throttle" on diesel engines at all!
It's just fuel man!

Will that motor fit in a Mustang?

I won't argue that since I don't own a 6.7 but I cry foul. How could my engine (pre-emissions or not) get 50%, that's fifty percent! more mileage? And I also cry foul that the dude averaged close to thirty mpg on a 1900 mile trip in the real world. Next you're going to tell me the slap-chop really can make egg salad in two slaps.
Can you say marketing?

I'm just going let you wait and make up your own mind when this stuff comes out.... It's really exciting.
Haven't BMW and Mercedes been using Urea for a while now?

Pretty sure they have for 2-3 years now.

they call it adblue. Look how fast the 5 series diesel is... hmm.
Compact/midsize pickup with a little diesel that still has 300 Ft/Lbs and gets 30MPG, oh hell yes! WANT!!!

Yeah, but those guys are trying to claim that a 3/4 ton full-sizer is getting mid 30's 
And I bet the superfine crystals in the Smooth Away really remove unsightly hair in one swipe too.
