Following the development of the Zeta architecture and because of its position as the GM global center of RWD development, GM Holden in Australia led the final design, engineering, and development of the Camaro. Original plans for the car included sharing the chassis with the Impala, which was to be switched to the Zeta platform. However, a 2007 energy law drastically changing the Corporate Average Fuel Economy forced GM to scuttle plans for replacing the W-Body platform of the Impala. The new Camaro was produced at the Oshawa Car Assembly manufacturing plant in Canada. 2,750 jobs would have been lost at the Oshawa manufacturing plant which had been originally scheduled to be closed in 2008; some of these jobs were saved due to the new Camaro's production. This new product program and conversion of the Oshawa plant to a state of the art flexible manufacturing facility represented a US$740,000,000 investment.
