Buick Regal GS Turbo Beats Everyone in Output

The original, and larger, 2.2L Ecotec I-4 was developed by a 1994 partnership among GM’s U.S., European and Australian powertrain units. They put their best heads together to create an innovative, all-new engine to satisfy preferences and requirements around the world. The project was based at England’s Lotus Engineering, intentionally far away from the partners’ home organizations.

Very Interesting bit I do see that ...

At that point in the development, GM's Ecotec team could have rested on its laurels and focused on the all-new family of Ecotec I-4s scheduled to debut (starting with a naturally-aspirated 2.5L in the ’13 Chevy Malibu and a new 2.0L Turbo in the '13 Cadillac ATS) in mid 2012. But someone decreed there first would be a still-hotter variant of the existing I-4 turbo for a special Buick Regal.

And this is an all GM creation. And this is the amazing part is...

GM leadership also requested this variant be developed 26 weeks faster than usual. The challenges involved in accomplishing those output levels while meeting all of GM's quality and durability requirements were toughened by doing it on an accelerated schedule, Andersen says.

Furthermore, the 2.0L had to be a credible replacement for a much larger V-6, so a top priority was being fun-to-drive.

couldn't they connect two of those engines together at the crank and make a V8?

I don't see how (as claimed from the article) 270hp from a 2 liter is the highest factory hp/l out there when the Mitsubishi 4B11 is putting out over 20 hp more from their 2 liter four.

ON EDIT, perhaps the SAE never certified the 4B11, but still...VVT FTW on all of these modern powerplants.
