This sinister Tahoe gets a lowered ride height and a rise in chrome content. While it may seem that the truck's only mission is to look cool, it is actually a showcase of GM accessories for the present and the future. Many of the elements, including a cat-back exhaust system and headrest-mounted DVD players, are available today. Some are coming soon: The big wheels, ground effects, and billet grille are accessories that will be available soon, while the lowered suspension and carbon fiber interior are still in the concept stage. While all of this is great, we're excited about this truck because it hints that a Tahoe SS could be in the works-the folks at Chevy wouldn't make that body kit or those big wheels for nothing, would they?
