About two years ago we first brought you news
that General Motors was developing a twin-turbocharged 3.0-liter V-6 engine that, coupled with direct-injection technology, would serve as the General’s rival to Ford’s popular V-6 EcoBoost engine.
Code-named LF3, performance of the new engine was reported to be similar to Ford’s 3.5-liter EcoBoost V-6, which is rated at 355 horsepower and 350 foot-pound of torque.
It was also reported that the LF3 unit would debut in the Cadillac XTS
, though so far the upmarket sedan has only been announced with a naturally-aspirated 3.6-liter V-6.
Fast forward to today and GM Inside News
, the same source that broke news on the LF3 engine, is now reporting that GM is working on not one, but in fact two twin-turbocharged and direct-injected gasoline V-6 engines.
The second engine will be a bigger unit based on GM’s 3.6-liter V-6. GM even hinted at such a possibility with the unveiling of a one-off Camaro concept
back in 2009 that was developed together with comedian Jay Leno and featured a twin-turbocharged 3.6-liter V-6 tuned to deliver close to 420 horsepower.
Possible applications for the pair of force-fed V-6 engines would probably start with Cadillac’s range of models, including the XTS and next-generation 2014 CTS
. There’s also a chance that Cadillac’s highly-anticipated ATS-V, the performance version of the new ATS
, will forgo a V-8 engine and pick up a blown V-6 instead
Stay tuned for an update.
