Yeah thats pretty neat. At 180 HP, that puts it close to our C4 stock with half the motor, lol! Breaks my heart to see modern rice burners with more HP but at least this one has the Chevy heritage. Keep Hope Alive!!!

V8's have always been capable of one horsepower per cubic inch and even 100hp per liter. It's manufacturers limiting them rather than stretching their potential.

That's funny, I was just the other day thinking it had been a while since any news on HCCI. I thought maybe GM gave up on it, since all you hear now is about hybrids, the Volt, etc. Then I noticed the article you linked up is almost a year old... You got my hopes up, then dashed them quite expertly.

How many rice burners have you seen with 330 to 350 lb/ft of torque? Thats a true measureable unit of power, not hp.

Cool concept....works like a disel but not all the time. I'd buy one if they had a V8 version....but with my luck they would come stock with Multec fuel injectors 
IMHO if the current price of gas averages continue where they are or drop a bit consumers and manufacturers alike won't invest as heavily in "newer" "lower horsepower for better mileage" concepts that have little impact on their overall average cost of automotive operating costs. If I was forced to choose a low hp mileage making machine this HCCI would be a better alternative to those high priced battery lugging hybrids. The hybrids seem like a good cost saving alternative initally until you have to change the battery banks out....$,$$$...all that money that was saved on gas then goes bye bye to the battery companies.....suckers.
Go GM!

Come on fellas it was a joke. I wasnt even bashing our motors, just the EPA that has kept ours from thier full potential. Technologies today have advanced 4 cylinders so far that they dont put out 85 horses anymore and they do so on less fuel than 25 years ago. If we could forget restrictions from the EPA, our 350s can be efficient and produce amazing amounts of horsepower. I am certainly not going to trade my 85 in on any rice burner.
