REPORT: GM's RWD architecture will downsize and survive

General Motors may be lacking the cash to develop any new rear-drive platforms, but reports out of Australia suggest that the existing Zeta platform that underpins such models as the Holden Commodore and new Chevrolet Camaro will carry on for at least another decade.
GM's Australian subsidiary only finished development of the current Zeta platform a few years ago, and it's not about to flush that down the toilet. However the next Commodore, currently sold in the North American market as the Pontiac G8, is likely to downsize for the next generation, anticipated to debut in 2013 and carry on through 2020. Along with the reduced size and heft, the General could use smaller, more efficient, though still powerful engines, employing direct injection and/or turbocharging like the Cadillac and Saab variants of the V6 already used by Holden. As we've discovered with vehicles like the Pontiac G8, GTO and the new Camaro, what's good for the Australian market is, in General Motor's eyes, good for North America, so fans of rear-drive American muscle have some hope to hold onto yet, mate.
