General Motors has released new information on its top-of-the-line 2012 Buick LaCrosse equipped with a new and more potent version of its direct-injected 3.6L V6 engine that joins the freshly released standard 2.4-liter four-cylinder engine with eAssist, which we’ve already told you about in a previous article.
For the 2012 model year, the direct-injection 3.6-liter six-cylinder unit has been upgraded with several new features including a different cylinder head design, larger-diameter intake valves in the heads and new, longer-duration intake camshafts.
