GM considering compact RWD platform to rival 3-Series?

General Motors is considering a new rear-wheel-drive platform that could be used to create a compact sedan to rival the BMW 3-Series or Lexus IS250. Lutz said developing a new platform is preferable to shrinking the larger Zeta architecture. "One of the things we'd like to investigate - and I stress, investigate - is a smaller, lighter, rear-wheel-drive architecture," Australia's Drive quoted Lutz as saying.

Lutz didn't say in what markets the platform might be used. Given the resurgence of rear-wheel-drive in the United States -- and the popularity of vehicles like the 3-Series -- it seems highly likely such an architecture would be used in America. In Australia, there's speculation the platform could be used for a reborn Holden Torana. GM unveiled a Torana concept (pictured) in 2004.
