The first 2013 Cadillac ATS compact luxury sport sedans intended for public sale are built at the Lansing Grand River assembly plant Thursday, July 26, 2012 in Lansing, Michigan. GM employee Theo Johnson tests the brake system on an ATS assembly line. The plant underwent a $190 million upgrade for ATS production, adding a second shift and 600 new jobs. The ATS will arrive in dealer showrooms in August. (Photo by John F. Martin for Cadillac)
