Twin Turbo V6 is a go! The LF3.....
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.
