Hmm... very interesting.

The result of all this is an engine that gets 27 percent better fuel economy than Nissan’s 3.5-liter V6, at roughly the same HP and torque. According to Reuters, at a press conference Nissan engineers said the new engine matches turbodiesels in torque, and is actually cheaper to build than modern turbodiesel engines.

What they fail to mention is this technology could also be used on diesels to further improve their efficiency as well (I would imagine at least). It would help deal with emissions as well as NHV and cold start conditions as well as efficiency... But you can't say that and also have a sensationalistic article title I suppose.
