While details are limited, a source has stated "We're finalising the four-door showcar of the ATS first. Then we'll follow quickly after with a wagon, a coupe and a convertible." The concept will likely be shown at a motorshow later this year.
Perhaps the most interesting detail is the report of an ATS convertible. It seems that Cadillac hasn't decided whether to use a conventional canvas roof or a folding metal unit. As the source said, Cadillac is "not too sure about the compromises of a folding hardtop."
Expected to be launched as a 2012 model, the ATS will replace the Saab-based BLS. It will rival the BMW 3 Series, Saab 9-3, Volvo S60, Mercedes C-Class and Audi A4/A5.
