It sips gas, like a true diesel, using cheaper fuel.
I hope the big 3 emerge from this mess strong, we are a 3rd. world country without them....

Yeah I heard someone from GM talk about this, but I don't see how this can be cheaper, more reliable and more efficient than a good old diesel engine. Maybe it will be eventually, but it's not even available yet. And if history is any guide, the Germans or Japanese will beat them to the punch and GM and the other 2 will be lucky to play catchup.
