2013 Chevrolet Impala Imagined by Casey/Art and Colour

I've got to say, this looks really good....
"2013 Impala—The next large Chevy sedan will be based on the same architecture as the new Cadillac XTS. I've created a Chevy version of that car, and I'm guessing it's pretty close to the real deal. I've used classic Impala logos and wheels, as well as very 1961-like Chevy lettering on the hood. Compared with the XTS, I've simplified the bodysides and given it a late-model Impala greenhouse, as well as smoothing out the trunk shape."

Chicago 2009: GM finally rolls out Corvette Stingray Concept

General Motors used the Chicago Auto Show to introduce the world to its latest concept vehicle, the Corvette Stingray, which will be featured in the upcoming Transformers: Revenge of the Fallen movie on June 26th. According to GM, the vehicle is nothing more than a styling buck that was influenced by the original 1959 Stingray racer when it was spotted by director Michael Bay while he was touring GM's operations looking for inspiration for the first Transformers movie. Don't expect this concept to spawn any sort of production vehicle, which, needless to say, is a shame.

In robot mode, the Corvette Stingray Concept will take the form of Sideswipe, who will reportedly be a skater with wheels for feet. The General doesn't have anything in the way of new product to show off here in Chicago, so it's using the blockbuster movie to drum up interest instead. It's working... sorta.
