The ATS is a small rear- and all-wheel-drive luxury sports sedan engineered to compete with the BMW 3 Series and Audi A4. The ATS will begin production this summer and will be built alongside the Cadillac CTS sedan, coupe and wagon in Michigan.

Cadillac says it’s pitting the sedan against the best in the category, with a lot of the engineering and tuning occurring in Germany and sometimes at the vaunted Nurburgring test ring. You can check out that testing in the video below. We’ll learn more details at 2012 Detroit auto show.
