For the 2010 model year, the big powertrain news from General Motors in the U.S. has been the launch of two new direct injected engines, a 2.2-liter four cylinder and a smaller 3.0-liter version of its high-feature V6. The latter engine uses its new fuel delivery system to help it achieve similar output to the previous port injected 3.6-liter while using less gas. That engine will see duty in several vehicles for the new model year, including the new Chevy Equinox, Cadillac SRX and CTS and the Buick LaCrosse.

It looks like this powerplant is heading down under to find a home in the Holden Commodore. The new 3.0-liter V6 will be paired up with a new 6-speed automatic transmission and should achieve similar performance to the 3.6-liter while improving efficiency from 22.2 mpg (U.S.) to an estimated 24.8 mpg (U.S.), a nearly 12 percent bump. The new DI V6 joins other alternatives in the Commodore iine-up, including a factory offered LPG system and an upcoming flex-fuel version. For the near term however, Holden isn't planning to offer any turbocharged four cylinder engines in the Commodore.
