DETROIT -- In an effort to streamline its global engineering, General Motors is inching closer to a decision on its "homeroom" strategy.
Within GM, the homeroom concept assigns a vehicle program to a regional engineering center in one of GM's four regions: North America, Europe, Asia-Pacific and Latin America-Africa-Middle East.
Some regions have emerged as favorites for specific architectures, but much remains unclear.
In the future, five key global architectures will play a prominent role within GM: Gamma, Delta, Epsilon, Theta and Zeta.
The Epsilon front-drive, mid-sized-car architecture, which is used for vehicles such as the Pontiac G6 and Opel Vectra, likely will be assigned to GM's German operations in Europe.
GM's Australian subsidiary, Holden, is taking the lead on GM's new Zeta architecture. Zeta will be used to produce rear-wheel-drive premium vehicles, including the next Pontiac GTO.
North America and GM Daewoo Auto & Technology Co. in Korea appear to be sharing development of the Theta SUV architecture used for the Saturn Vue and Chevrolet Equinox. Some development of Theta could take place in Korea, but North America still could be the homeroom of Theta.
The location for the fwd Gamma minicar and Delta small-car architectures are unknown.
