GM'S TOTALLY NEW DIESEL ENGINE--TAKE A LOOK AT THIS!!!

GM has amazing technologies. They simply need to leverage it.

For anyone who disagrees, I'll stop you here. The 599 uses the same suspension technology as the new ZR-1 Corvette--which was licenced from GM.

 

Interesting design. There is a rumor, that there will be an 8 ltr motor for the full sized trucks. Wonder if it will employ the same features?

Pretty remarkable that this new 4.5 liter diesel produces power similar to the current 6.6 liter Duramax, and with better mileage and emissions.

Agreed that GM has absolutely amazing engineering capability, probably the best in the industry... too bad that the bean counters have until recently prevented them from actually producing such things. BMW's new petrol twin turbo V8 that's going into the X6 first (and probably other cars in the future) also uses a reverse head configuration, so interesting to note that BMW and GM both reached a similar brilliant solution concurrently.

 

They need to bring back the 3800!!!! dammit!.

But this new engine is close enough.

 

Nice work GM.

 

I know the engineering at GM must be incredible.
But IMO it always starts with; "whats the cheapest way of..."
Remember the 4-6-8 engine and Diesel conversion gas engines ?
I will leave the experimental stages of product evaluation to those customers with thicker blood.
That said I really hope they are on to something.

 

GM rules.

 

Not bad....gotta see the real life outcome of this

 

GM technology is amazing, but as stated the bean counters hold sway, hopefully less so as GM is on a roll...

 

I knew it was only a matter of time before the "converted gas engine" myth would rear its ugly little head. The Oldsmobile diesel was not so much a converted gas engine as it was an intelligent use of existing ancillary parts. By giving the engine the same external dimensions as the current gasoline engine, all existing accessories bolted right up, and the whole assembly dropped right into the same space as the gas engine. The block was an all-new high nickel casting specifically designed to be a diesel. The heads had the first use of pre-chambers for what was at the time, the worlds quietest diesel.

Its downfall was GM corporate policy, not the design. the Oldsmobile diesel was supposed to be released in limited numbers, with a "whole-engine" warranty program designed to test the engine out in real-world circumstances so that the bugs could be worked out of the design. When a customer came in with engine problems, the original warranty would have the engine removed, and a warranty engine installed in its place so that the original could be sent back to Oldsmobile for evaluation. Unfortunately, GM corporate forced Olds to release the engine in large numbers, through not only Olds, but also the other members of the GM family. Olds was very much against this plan, and tried hard to keep to their original idea as they felt the engine needed more development; development that could only come by putting the cars into the hands of select consumers, and then closely monitoring the outcome.

By the end of the Olds Diesel's short life, all of the major bugs had been exorcised and the engines frequently made the 200K mile mark with little more than standard maintenance. The biggest impediment to longevity at this point was its too-small oil capacity, the effects of which could be avoided if the oil was changed every 3K miles.

Shiny Side Up!

I wonder how they deal with the heat from the exhaust "manifolds" if it goes inside the Valley?? Ive seen them cherry red sometimes its seems like it would contain the heat if the Exhaust went toward the inside of the engine valley..
