Its a diesel they were going to roll out just before bankruptcy. Its a Isuzu built 4.5 litre DuraMax light duty V-8. 1 month before it was to be sent into production, it got canned in a "financial securing move" what ever the hell that means. Its been sitting on the shelf since. I was chomping at the bit to get ahold of one of them, back when I was working for GM. But alas, bankruptcy, and a lay off happened.
The EcoDiesel in the Ram was also built for GM to be put into the European Cadi CTS. Also canned at bankruptcy. It has been used in the EU for 3 years now in other vehicles, so it is a proven diesel. But our EPA restrictions are tighter than the EU's. They are hoping to NOT have problems with the DEF systems, and other EPA BS.

As far as I can tell, that was the last time this engine was talked about. I would be so happy to see one in a 1500 Sierra. But GM has always had a very nasty habbit of trashing something just when they perfected it. The Pontiac G8, the Pontiac Fiero are just a few examples of GM's pure ignorance to their buyers needs/wants.
