Could this be the New Cadillac ATS Small Sports Sedan?

A bare-shell of an unidentified model shown in a introduction video on GM�s corporate site caught the attention of a forum member of GMInsidenews. The team over the website believes that this could be an early prototype of the upcoming 2014 Cadillac ATS sports sedan, with which GM wants to compete against the BMW 3-Series and Mercedes-Benz C-Class saloons.
