Even though GM’s revolutionary 4.5-liter V-8 Duramax light-duty diesel is indefinitely shelved, some of the same advanced ideas still live on in Ford’s upcoming heavy-duty oil burner, code-named “Scorpion.” The all new, Ford designed ‘Scorpion’ 6.7-liter V8 diesel engine will replace the current Navistar supplied 6.4-liter V8 Power Stroke by 2011.
Our spies have once again caught Ford’s new in-house-designed 6.7-liter V-8 diesel under the hood of a Super Duty prototype. An earlier picture showed mostly radiator, but this newest photo shows the highly complex air intake, exhaust gas recirculation and tight packaging needed to support this technically sophisticated and highly powerful clean diesel.
Industry sources say the Scorpion has the same unconventional reverse flow intake and exhaust setup that was a hallmark of the GM 4.5-liter V-8. Airflow through the cylinder heads is reversed (relative to conventional diesel-engine design), with the exhaust exiting directly into dual sequential turbos sitting in the engine’s valley. The Scorpion will also use lighter aluminum cylinder heads, abandoning the cast-iron heads found in today’s 6.4-liter V-8 Power Stroke.
The latest power targets are said to be more than 390 horsepower and 720 pounds-feet of torque. Today’s Power Stroke diesel is rated at 350 hp and 650 pounds-feet.
Scorpion fuel economy is expected to improve by 3 mpg or more compared to the current Power Stroke. Helping the Scorpion’s mileage will be a new six-speed automatic transmission, like that found on the 2009 Ford F-150.
The Scorpion will use urea (aka diesel exhaust fluid) selective catalytic reduction to meet the EPA’s tough new 2010 nitrogen oxide exhaust standards. NOx is a major air pollutant that contributes to smog, asthma, and respiratory and heart diseases. It’s a byproduct of diesel’s high combustion temperatures. SCR requires periodic maintenance on the part of the driver.
Another notable change: unlike the 2008-09 Super Duty, the hood on the Scorpion-powered truck lifts separate from the grille instead of as a single piece.
Job 1 production is expected to start this fall at Ford’s engine manufacturing plant in Mexico.

Hopefully this will erase all the Navistar-related bad press issues they’ve had to deal with

They should offer this in the Fiesta. I’d love to see a tiny car towing the motorhome for a change.

That’s a lot of flippin’ torque in a light-dutypickup. I hope this is one Ford can stick with for awhile. It’s the third engine configuration just since the bulletproof 7.3L saw 2002 as its last model year. Looks like a winner, though.

Don’t forget beer beatus, it’s un-American to work on a car in a buddies driveway without beer.

Lol Beatus, actually lastnite I made snow crab legs, asparags wrapped in bacon, and roasted herb potatoes. Tonite is shrimp tacos with mexican rice. I’m ur grub guy. And if all else fails, there is an In N Out burger down the street from my house (I’m there bi-weekly)
Ok yeah that torque figure is awesome! Can u imagine 700lbs of torque in a car weighing like 3k lbs!??!! O M G

Eff1Fifty, your grub sounds good. As far as beer goes, make mine an O’Doul’s. I love the taste, but I can’t stomach alcohol.

O’Douls is all I drink when I’m out on my bike, I’m pretty paranoid about that. It’s actually not a bad beer (Though I’m a Guinness man myself).

Once again Ford continues to make the most bad-ass, powerful trucks on the market.

Pftt…this thing will bomb just like all other Ford appliances.
FORD was the reason the 6.0 had so many issues. Navistar didn’t have NEAR the issues with the 6.0 when built to the PROPER specs.
The one thing Ford doesn’t have to worry about on this engine is spark plugs shooting out of the head…I guess Ford realized that they were to inept to design a proper spark plug so they ditched them all together.

realist-so what are those proper specs?? Ford could of saved 100’s of millions of $$ if they had those elusive specs. Navistar didn’t have to meet emission specs that Ford did. EGR coolers, for one make up half of the 6.0 problems. Spark plugs shooting out of cylinder heads stopped happening when the “proper torque specs” were administered. I for one own a few of those “sick 0″ engine trucks. One of them has been in the shop nonstop, the other one never is at the dealer. I am sooooo happy to see the urea aftertreatment in this new truck. The high temperature exhaust treatment for lower NoX is a very unstable way to acheive what “cat piss” will do very easy.

2011MY changeover for Super Duty is in Feb 2010. Job1 on these diesels is supposed to be in Dec if our fleet guy is correct. Deliveries should start in April.

I’ll manage the operation and drink!
It’ll end up with 410hp and 750 tq by the time Ford is ready to market it. Niiiice.
