GM makes a move

Great article,

It is interesting to see GM announce a new diesel almost 2 years before it goes into production, especially with so much detail on the technical features. I am impressed with the 72 degree V and the zero manifold. GM notes that it is designed to accomodate the same space as a small block, I wonder if it going to also be a similar weight?

Travel is in my blood, adventure is my passport, aluminum is my favorite construction medium, and therefore, an Airstream was my destiny.

I may be ready for a new duramax in 6 or 7 years. But it'll have a lot to live up to if it matches the current version.

Unveiled during a media briefing at its Milford, MI, Proving Grounds, the new 4.5-L powerplant will be one of the most powerful, lowest-emitting, and package-efficient light-duty V8 diesels in the marketplace, company engineers claimed
NO technical details in the article. Looks to me that the engine is child's height and probably well over 1/4 of ton heavy. That will eliminate it from lot of popular vehicles.
Volkswagen mounts 300 HP diesels in compact cars for almost a decade.

It's really about time. I am shocked, though I shouldn't be that GM is releasing the smaller diesel in Europe first.

"The Duramax is package-protected for closed-loop cylinder pressure monitoring, a technology GM will introduce on its new 2.9-L turbodiesel V6 next year in Europe."

So, the 1/4 ton issue is fairly moot IMHO. Of course the 4.5L might not be a solution for say a Malibu, but the 2.9L might do the trick for most of the car lines domestically. The 4.5L I see as a Suburban, Tahoe, Silverado (and their GMC and Caddy similar lines) offering. **Might** even make it's way into the 3/4 ton and larger markets too....but I'm just speculating here.....

Computers manufactured by companies such as IBM, Compaq and millions of others are by far the most popular with about 70 million machines in use worldwide. Macintosh fans note that cockroaches are far more numerous than humans and that numbers alone do not denote a higher life form. -NY Times 11/91
