Fracture splitting the journals is possible because CGI is used as the block material. Audi uses this for their diesel engines – it’s extremely stiff and very well suited for a diesel block – far better than aluminum with only a reasonable penalty in weight because it can be cast thin.

I must tip my hat to GM for this design – it’s really innovative and not what I’d expect from them.

Betcha this engine wins the awards next year.

I agree… Its been years since Ford could come up with powertrains like GM. Now when it comes to truck chassis’, towing capacity, & payload they do have to bow to Ford.

I wish I could just put a GM diesel in a new 2009 F150. From what I hear, Ford’s draggin their feet about their diesel because its comsumes 20% less fuel BUT fuel costs 21% more…

WTF!!!!

I wonder if company will live long enough to place under the actual hood of an actual car. I wish they did.

They ought to take the initiative and put this (with a little more HP) in a sports car.

Very good news. It sounds very promising, if the costs are low enough then this surely will leapfrog anything else out there. Good work GM!

STEAM! Build a freakin’ steam engine. It’ll be more efficient.

Whatever you were thinking, Johnny, THAT’s probably not one of them…

However, I know someone who will…

So, to be more specific, I’ll proofread and correct LLN’s posts for $10.00 per post.

It’s a great engine – too bad it is DOA in the U.S. market thanks to the ridiculously high price disparity of diesel fuel versus gas. Even if there is a net cost savings, very few people are going to sit down and do the fuel cost calculations to see it. Instead, they see $4.00/gallon for diesel versus $3.00/gallon for gasoline, and they buy a gas powered vehicle.

Until government steps in and does something about these diesel prices, new clean diesels like the 4.5L Duramax will be introduced to a dead market.

beatus, I have no doubt there are plenty of things you’d do for $10, so please try to be more specific.

Guess who’s buying a diesel… and yes I do have need for it…
Maybe not a lift kit, big wheels & tire’s, Banks power pack, but come-on now you really don’t expect me to be rolling stock trim… Do you???
Come-on kid, homes don’t let homes roll stock….

My mistake
The 4.4 from Ford doesn’t even make 400 lb. ft

500 lb ft will be the standard in the light-truck diesel class.
Ford better get to work, cus 430 lbs ain’t gonna git it

The text is probably just copied from some other lazy-as who didn’t bother to sPeLz cHek their work. It’s comforting to know that grammar and spelling are not part of a journalism degree.

LLN should hire me. I’ll do it for $10.00 per post.

this is going to be the most amazing engine theyve put out in years

Or perhaps grammar checker

“In fact, the new design is so success that GM is looking to use the technique in some of its future gasoline engines.”

Successful perhaps?

You guys at LLN really need to look into more carefully proofing your articles and maybe the occasional employment of the spell checker. Just a thought…
