Look where Ford took the 3.5L. Only 365hp with twin turbos. You can get 400+hp out of a TT 3.0L easily, but from the factory, it will not be anywhere near there. Realiability as well as fuel mileage (CAFE) comes into play. They are not going to put a 100,000 mile warranty on a 400+hp TT 3.0L engine. It'll be right around 350hp most likely with great driving manners and low end tq.

Ford Motor Company’s recent introduction of their twin-turbo 3.5L V6 has brought the industry limelight to high tech, forced induction V6 powertrains. Rumors of General Motors joining in on the turbocharged V6 arena have been around for several years now, however GMI has confirmed that The General really will be joining Ford in the high tech turbo bandwagon.
According to GM engineering sources, GM is currently working on a twin-turbo 3.0L V6. Development on the new engine is so far along that it has a PRO code of “LF3.” The naturally aspirated 3.0L debuted in several 2010 products with direct injection and has the code “LF1.”
GMI was not able to obtain projected power ratings on the new engine, however output is very application specific under new SAE testing rules. Sources did say to expect the engine to rival Ford’s EcoBoost 3.5L.
The engine’s introduction is expected in late 2011 or early 2012 in the Cadillac XTS. Sources also state that GM is looking to use the engine in the Cadillac ATS and possibly even the next Chevrolet Camaro. Cadillac has historically always debuted new variants of the High-Feature V6 lineup, so it comes as no surprise that the XTS is the likely to pioneer the 3.0L twin-turbo.
Most rumors surrounding the potential of a turbocharged V6 out of GM have centered on the company’s 3.6L V6. A couple of years ago GMI was told that GM had twin-turbo 3.6L V6’s in development that were generating as much as 435 horsepower. Information regarding the potential of a blown 3.6L silenced for years until GM showed a 3.6L twin-turbo V6-powered Camaro show car at the 2009 SEMA show. The Camaro show car was generating 425 horsepower

GM needs to be AHEAD of the curve, not behind it.

What gets me is the Idea that a TT V6 will get better fuel economy than a small displacement V8.
For modern proof of this - just Look for the 3.5L TT V6 in the new Taurus SHO, doesn't get any better fuel economy than the 2011 Mustang GT does. Yet the 2011 Mustang GT has 56 hp advantage.

The SHO weighs about 700 lbs more than gt .

700 lbs difference? I thought it was more like 300-400lbs difference. With the Taurus SHO weighing about 4,000lbs.
But 700 would put the SHO at about 4,300 lbs.
Still that big of a Weight increase could the TT V6 to get the same fuel economy as a 5.0L DOHC V8.

735 pounds, comparing base weight of automatic models. As good as the Mustang EPA numbers are, the Taurus SHO numbers are even more remarkable, considering the weight.
I think there's little question that the DI V6 turbo is more efficient than even a very well executed PI V8. If it weren't there'd be little reason to even suggest replacing the Mustang V8 with the V6, as the DI V6 turbo has got to be quite a bit more expensive to build, and it will never have the same throttle response as the NA engine.
The Chevy Cruze will have 1.4 turbo and 1.8 NA engines available. Both are PI, IIRC, and make about the same power. The 1.4 turbo will get better mileage but cost a little more.
