The Flint Journal took part in a press event with a number of new GM models including a number of their upcoming trucks. Most interesting among them is the GMC Sierra Hybrid. The pick-up works just like any other hybrid but of course is a truck so that's new. There's also a Chevy Trailblazer with displacement on demand that shuts off half the cylinders at cruising speeds to save gas. For insight on the new Hummer H1, Chevy SSR (with more power), Cadillac CTS, Chevy Colorad Xtreme and Buick Rainier read the full story.
