Interesting... Chevrolet SS... Is that supposed to be like a new Camaro concept or something? That would be neat, but you know they'll never build it. From what that literature says it looks like it would give the C6 too much of a run for its money and you know how that goes... GM always has these internal conflicts about its own being quicker or handleing better than the vette.
The other thing that this article didn't mention, that i remember reading somewhere, was the designer of the PT Cruiser is the one who came up with the design for this particular SS. The concept model also had 20" rims.
