This is a presentation led by Thomas Stephens of GM Powertrain during the introduction of the Sixteen. The original thread is here

Here is the presentation.

Facts learned:
-GM will be pushing for hydrogen fuel cell cars between 2010 and 2020
-Required power output of at least 60hp/L (good bye old 3800 at a mere 53hp/L)
-CVT will go into the Ecotec cars in the near future
-There will be a 6.0L base Gen IV, a 6.0L mid level Gen IV, and a "6.X High Output" version
-The forced induction ecotec motors will be 2.0L and 2.4L. No turbo ecotecs are planned for North America (this is sad. To compete with the Cobalt SS with ricers, you need turbo's. It's an image thing I guess to have a turbo.)

We know most of this news already from insider sources, but this conforms it all.

 

That pretty much confirms that the 5.7's days are numbered.

 

Excellent find!

 

I still think they need to research more fuel alternatives... even though you can make hydrogen from h2o, its a long and expensive process and the bi-product (of all things it could be) is carbon monoxide.. (about %50 is useless carbon monoxide..)

Oh well, the hydrogen engines that bmw built a few years ago made me believe that at least performance can still be obtained. (8 and 12 cylinder prototypes with decent top speed and quick times)

 

The process of extracting hydrogen gas from water would yield oxygen gas, hydrogen gas, and a metal salt (corrosion) on the ends of the wires. No carbon monoxide.

(edit: Unless you're referring to the coal-burning plants where the electricity would come from for this extraction.)

And the process of combusting hydrogen gas shouldn't yield anything but water.

2H2 + O2 => 2H2O

 

That's theoretically true, but in practice you'll get small amounts of some other byproducts, notably oxides of nitrogen due to the nitrogen in our atmosphere and high combustion temperatures.
