Cadillac ATS: Sneak Peek

GM says the XTS — built in Canada — will be launched in spring, and the ATS — built on a new rear-wheel-drive/all-wheel-drive platform — will launch in summer 2012.

The current entry-level CTS sedan has a cramped interior on par with the BMW 3 Series, which was the benchmark for the new ATS. We wonder how much interior space the ATS will pack.
