The new model will be based off the upcoming Camaro's platform, currently under development by the hoons at Holden in the land down under. The 2009 model will differentiate itself from the 2007 model in both length and width, providing more interior room and allowing the wheels to be pressed to the outer limits of the new sedan's body.
The primary question that needs to be answered before production begins is whether the Impala will remain amongst the Camry's and Accord's of the world, or will move upmarket to limit competition with the newly redesigned Malibu. Considering the Malibu's growth and upgraded interior, there may be room for another price-point in Chevy's lineup.
We're downright ecstatic that GM has seen fit to not only send the Impala's power to the rear wheels, but share a platform that will instill some desperately needed driving characteristics to its four-door sibling.
