GM’s product renaissance is set to continue well into 2012, with the launch of two new Cadillac models. The ATS will be a dedicated competitor to other entry-level, rear-drive luxury sport sedans. As of right now, the ATS’s launch is planned for the summer of 2012, with production planned at the Lansing, Michigan Grand River Assembly Plant. We can’t see much from the teaser image, but smallest Caddy looks to refine the CTS’s design language, with similar sharp angles and creases. We’d expect to see the ATS debut at one of the big four American auto shows (LA, Chicago, New York, or Detroit).
