Well GM has been making cars with DI, turbocharged, start-stop, and cylinder deactivation for a while now. This is the first motor to incorporate all those features into a V6 architecture. So these while a first being incorporated all at once are not really new technologies. But people love their marketing terms.
The real technologies in this engine are the charge air - throttle - intake manifold system. This makes the car rev better and allows it to be more responsive. Also the two stage PCV system. Plus a number of improvements and very specific use of various grades of materials for good optimization and NVH properties. I've never seen an engine that uses parts of so many varying materials.
It's like they let the engineers at GM run wild with this engine and locked the accountants in a room and just told them to shut up and pay the bills.
