Engine geeks, pay attention. GM Powertrain's working up a new, 3.6-liter gasoline direct-injection engine with variable valve timing, just in time for the 2008 model year — though its first application in a car won't likely appear until 2009. It'll be GM's second DI engine in the US, after the new, turbocharged 2.0-liter four (pictured) to be used in the Pontiac Solstice GXP and Saturn Sky Red Line. GM says the new engine, which will be used internationally, will offer a 15% power bump over its current crop of V6s, which vary in horsepower from 240 to 267, as well as improve fuel efficiency. Of course, the new mill will arrive more than three years after Toyota's 3.5-liter DI engine, and six years past GM's original deadline for a major launch of DI engines (but who's counting). Could it be the new powerplant uses technologies borrowed from Isuzu, which was the first to the US market with a 3.5-liter direct-injection six, which showed up in the failed ...wait for it... Isuzu Axiom (respect!).
