GM appears to be going from 0-60 with blown V6's.

Nearly two years ago GMI broke news that General Motors is working on a 3.0-liter twin-turbo V-6 to get GM on part with the industry trend of utilizing blown V-6's. Until recently it has been assumed that GM has only one twin-turbo V-6 in the works, which makes a lot of sense considering the company is about to launch the fifth generation of its coveted Small Block V-8 lineup. Instead, GMI has learned that GM currently has two twin-turbo V-6's in development.
The saying goes, "there's no replacement for displacement" and apparently GM feels the same with regards to their V-6 engines. Sources have confirmed to GMI that GM is also working on a twin-turbo version of its 3.6-liter V-6. This engine will supplement the 3.0-liter twin-turbo V-6 that GMI previously confirmed.
Back in 2009 GM and Jay Leno showcased a Chevrolet Camaro concept at the SEMA show that housed a twin-turbo 3.6-liter V-6. In that application GM claimed the engine generated 425 horsepower. GMI has not been able to confirm power figures for the production version of the twin-turbo 3.6-liter, but in excess of 400 seems like a plausible estimate considering the company is still developing a 3.0-liter variant of the blown engine as well.
As previously reported, expect the 3.0-liter twin-turbo to show up first in Cadillac models, including the XTS and CTS. Both sedans will eventually have the engine as an option, with it being mated to an eight-speed automatic. The engine is expected to trickle down through the GM lineup over time, similar to GM's typical new engine roll-out.
The 3.6-liter twin-turbo is expected to first show up at Cadillac as well. Earlier this week reports surfaced that Cadillac has decided to go with a twin-turbo V-6 for the upcoming ATS-V performance car. According to sources, that twin-turbo V-6 will not be the 3.0-liter, but rather the first application of the twin-turbo 3.6-liter, suggesting that the larger displacement could be reserved for performance applications. Perhaps the 3.6-liter could even end up being a Cadillac exclusive engine? At this time no other applications of the twin-turbo 3.6-liter are known.
