Report: GM developing twin-turbo 3.0L V6 to fight EcoBoost

" These are the days when V6 engines are getting all the love, and the reasons are obvious. Chrysler has finally got its Phoenix Pentastar V6 on, and down under General Motors recently rolled out the facelifted Commodore line with its 3.0-liter SIDI V6. The point is to provide solid power and go easy on the gas, and in the U.S. the V6 that's been making that point very well is Ford's 3.5-liter V6 EcoBoost found in the Flex and Lincoln MKS and MKT.

GM's got its eye on that lump as it prepares a twin-turbo 3.0-liter V6 engine provisionally called LF3, a derivative of the same High Feature LF1 V6 (pictured) in the new Commodore. According to GM Inside News, we should "expect the engine to rival" the EcoBoost. The Ford motor comes in at 350 horsepower and 355 pound-feet of torque, compared to the 3.0-liter SIDI V6 at 270 hp and 213 lb-ft.

Where would this engine appear? Up at this end of the Earth we can probably expect it in the newly confirmed Cadillac XTS (Cadillac worked with Holden to develop the HF1) and perhaps even the Cadillac ATS and the Camaro. Look for it in 2011 or 2012... hopefully."
