Its actually a 3D computer model of a drawing that was conceived by Chris Pauwels. There's been much talk about the new Camaro over at
http://www.camaroz28.com and
http://www.cheersandgears.com . The model was done up for a recent Popular Hot Rodding article on the new Camaro (or whatever what it will be called. See the story it is an interesting read >
The Return of the Camaro in 2007.)
The author, Guy McCoy, is a regular on both those websites. All that is known is GM is secretly developing a Chevy V8-RWD "Camaro-like" coupe which may be launched for 2007 or 2008 MY. What it will be called has not been announced. Futhermore, several people have said that the PHR "concepts" take on more of 1st gen feel than what insiders have told them. There is another similar drawing out there that looks more like a two-door version of the SS concept car, yet still meets all the basic critera.
The car will be developed in NA (US or Canada) and will be based on the Zeta chassis, which is also the base for the 2006 GTO. There will be other derivatives off of the Zeta platform, including possibly Buick. (nee Velite?)
