As far as I know, Delphi (which spun off of GM some years ago) makes some of the stuff GM uses in their vehicles. And up until now, I don't think GM has any sort of variable lift technology. They've got cam phasing...but that's a timing adjustment.
Then the article mentions this thing's ability to work with HCCI...GM's the only company that's
really looking into HCCI engines. The German's might be, too....but I don't think they buy from Delphi.
Overall...I thought this was a very interesting feature we may see on GM engines soon.
