HCCI: GM making advances with its "newest" fuel-economy improving engine tech

From MotorTrend.

Sorry if its a repost or already known information.

Some info on GM's Homogeneous Charge Compression Ignition (HCCI) engines.

I read about it before (I think Car and Driver)...it's a pretty cool technology, and I hope it works for the long term.

Looks like they're making very rapid progress with HCCI. They weren't even talking about this a 18 months ago.

I bet with its narrow band of operation, it's well suited to powering, oh, say, a range-extender engine on, oh, maybe, plug-in hybrid?

D'ya think?

What a great find. Most excellent.
Did anyone else catch the "using less than half the gasoline" comment?
Whoah.
I can see it now.....

Yes, I'll take two HCCI Camaros.
I'm doing my part for the environment.

i can see this in application by the end of the next year. 35mpg average here we come.
now i'm somewhat confured though, i know hcci comusts gasoline by compression, but is gm working on a system where they inject water into the cylinder every fourth cycle to reduce the gas usage further or is that a different system that i'm thinking of?

Finally some good news.

Interesting. Wonder if it'll add to the cost of the car at all?

No, all new technology is free and R&D cost nothing.

Great!
Let's get this science project in commercials and in the showroom!

Things like this cold help make Saturn a real volume-seller. "re-think?"

Every flimsy switch, every panel of sheetmetal not changed from platform mate, and every technology featured not put into the DIC, instrument cluster, or radio, has paid for this R&D science project.

I hope it gets deployed.
