DETROIT ? Despite earlier reports that it might have scrapped plans for a new family of rear-wheel-drive vehicles in North America, General Motors to the contrary has now expanded its Zeta architecture to include a variety of new products for Buick, Cadillac, Chevrolet and Pontiac, Inside Line has learned.
The first of the new Zeta models is the Pontiac G8 sedan, based on the Australian Holden Commodore SS-V and due in Pontiac showrooms in early 2008. It could be joined next spring by a new Buick Park Avenue sedan, based on the Holden Statesman and just introduced in China.
While those two rear-drive four-doors are only mildly revised versions of Australian products, the next wave of Zeta models for the States will boast unique sheet metal. They include the 2009 Chevrolet Camaro, which goes into production in late 2008 and should begin arriving at U.S. dealers in early '09. It will be followed in short order by the replacement for the Pontiac GTO, which is due in fall 2009 as a 2010 model and will continue to be built in Australia.
In mid-2010, Chevy will unveil its new rear-wheel-drive Impala, based on the Zeta platform and built in North America. (The older front-drive sedan may be carried over for a year, aimed primarily at fleet customers and rebadged as the Impala Classic.)
About the same time, the 2011 Impala will be joined by redesigned editions of the G8 and Park Avenue, which will join their Chevy counterpart on the same assembly (probably at GM's Oshawa plant in Ontario). The '11 Park Avenue may nudge the older Lucerne from Buick's lineup as the brand's flagship sedan.
Cadillac had planned to shift the front-drive DTS sedan to the Zeta platform for model year 2011, but instead may drop the car. Now comes word from suppliers that a future CTS will switch to Zeta, in 2013, as Cadillac phases out its current Sigma rear-drive vehicles.
What this means to you: GM's vision for rear-wheel drive appears to be wide-ranging in the post-2010 era.
