New for 2012

E85 ethanol capability is now available for the 2.4-liter Ecotec four-cylinder engine. A touch-screen CD stereo is standard on all models, and GMC IntelliLink enables smartphone integration and the ability to stream music from Pandora and other music services. The standard backup camera's image now appears on the stereo's screen, and a lane departure and forward-collision warning system is optional.
