Looks like GM may FINALLY be listening to the public! A legitimate diesel engine option for 1/2ton pickups and SUVs is a major breakthrough, IMO.

Also, a Hi-res pic of the engine can be found here

"despite sharing its name with the older 6.6L Duramax diesel that was developed in partnership with Isuzu, the new 4.5L Duramax was developed completely in-house by GM."
isuzu make great diesels and im suprised gm is doing this alone.
sounds interesting,but im not sure you need a v8 configuration.
what would be wrong with a v6 or i6 configuration?
less moving parts and things to wear out.
i think its more about marketing and the fact v8 sounds cooler than v6 .
btw good find bac

I wish it wasn't going to take so long to get here.

Late next summer.....15 months!!!! :Thumbup: That ain't too bad, least Toyota didn't beat us to the punch. LOL

You know, this is nothing new for GM. They offered diesels in 1/2 ton trucks 25 years ago. Nobody bought them. Somehow, I think THIS time is gonna be MUCH different!

thatll be coll if they acutally do it.

I'm hoping the mileage will be better than 30, 40 would be nice!

no chance
i would say about 26mpg
my diesel ranger gets 33mpg
and its only a 3.0L inline 4
my 4.2L superduty gets 23mpg and its a 4.2L

26mpg in a pickup truck would be a huge improvement over what GM 1/2 ton gassers get right now. I just hope GM doesn't get greedy and charge $10,000 extra for the option. They need to make it a viable choice for customers.

I thought they were saying a "25% improvement in fuel economy"?

If the average 1/2 ton gasser gets ~12 MPG around town/~18 MPG highway , that would mean the diesel would get ~15 in town/ ~23 highway.

I am dreaming of a diesel Yukon or Surburban... Aaaaahhh! :smoke

:Well they will pry have to have a dpf (maybe more for the 2010 emission jump) so I would say itll be at least (just for the dpf) 1000 more then the gas option, thats jsut for the dpf.

1/2 ton is probably 14 around town and the 18 highway sounds right. but I would hope for for better than 15-23 out of the diesel. Like I said I would HOPE. Still beats the gasser thou.

good greif, i get 20 consistently in a 4wd cc/lb. I hope they can do better than 25 but I'd like to see 30 or more.

Any idea how many of those were made?

VERY few, I'd say. Like less than 1,000, if I had to guess.

Thats about what I figured. I don't think I've ever seen one, other then in pictures.

it will be more then $1k more because it will also have the SCR and urea injection. As of right now the numbers that they are shooting for...HP and torque are very impressive for a small block diesel:Thumbup:
