Is this the 2014 Chevy for NASCAR?
General
It looks likely but I've also read the following at another site.
'It's pretty well accepted in the car industry that the next Chevy model will be a US version of the new Holden Commodore. Also Chevy and Holden in the near future will begin to cross develop a majority of their cars together.'
This is the Holden Commodore by the way. They use this car in Australian V8 Supercar competition against the Ford Falcon.
