GM-released Gen V V-8 video shows what appears to be some form of a turbocharged V-6.

It's unusual for us to miss something in a General Motors release, but we did with regards to a video of their Generation V Small Block V-8. During last week's announcement, the company released several small videos showing testing and validation of the new LT1 V-8, though one video clearly shows an engine other than the new Small Block testing on one of the company's tilt dynos. A keen reader of Corvette Online noted that one of the engines in the video did not look like the rest, and we have to agree.
The above photo has been captured from the video. Within the photo it is clear that there is plumbing for two turbochargers on the engine, with close ups revealing one of the turbochargers and the heat shield surrounding it.
It's difficult to say, and nearly impossible to confirm, but the engine in the photo does have some similarities to GM's High-Feature V-6 lineup. The block size certainly suggests this particular engine is a V-6, and the timing cover is extremely similar to that of the one on the 3.6-liter V-6.
Way back in 2010 GMI broke news that GM was working on a new twin-turbo V-6 to rival Ford's 3.5-liter EcoBoost V-6. At the time sources suggested that the company's 3.0-liter V-6 would be the basis of the twin-turbo engine. Since then GM has phased out most applications of the 3.0-liter V-6 and insiders report that the company will add two turbochargers to the well-used 3.6-liter V-6 instead.
Assuming product plans remain unchanged, expect GM's twin-turbo V-6 to first show up in the next-generation Cadillac CTS, though the engine is not expected to launch concurrently with the new car in mid 2013. Late 2013 or early 2014 would likely be a more realistic time frame for the twin-turbo V-6 to launch.
Between the new Small Block and this alleged twin-turbo V-6, GM Powertrain is clearly keeping very busy. Also - any GM technicians, feel free to chime in to aid in identifying this engine!
