GM twin turbo V6 to combat the Ford eco-boost?

We could easily see this power train finding its way into the Camaro!

Ford's twin-turbocharged 3.5-liter "EcoBoost" V-6 has proven to be rather successful, so it's not too surprising to hear that General Motors may be working on a competitive engine.

The EcoBoost competitor will likely be built off GM's "high feature" V-6 -- specifically, the 3.0-liter "LF1" V-6 used in the likes of the Buick LaCrosse, Cadillac CTS and SRX, Chevrolet Equinox, and GMC Terrain. Sources close to the program tell us that early prototypes of the engine -- code named LF3 -- were producing close to 400 horsepower before any spark timing or calibration refinement was performed.

Although the engine is certainly under development, there's still some speculation surrounding which vehicles could utilize the twin-turbo six. One possible application, according to GMInsideNews, is the 2012 XTS. The large Cadillac -- which is reportedly greenlighted for production -- was shown in concept form with a "high feature" V-6 mated to GM's 2-Mode hybrid system.
