That's what I thought. However, I have seen a very similar name on
other brands now (something like Vtech). Is GM licensing the technology
to others or is that just someone else using a similar name for similar
technology.

I am under the impression that this is GM's method to ensure lots of
turbulence in the combustion chamber. Is this right?
