After tons of speculation, rumors, reports, possibilities, and finally confirmation, the Cadillac ATS is finally a production vehicle. At GM’s Lansing Grand River plant, the production of the much-anticipated ATS sports sedan has finally begun, but don’t expect to see the ATS in showrooms any time this month. GM doesn’t expect to start delivering its newest addition until next month. Our estimation would be around mid-August, given the late start it got in July. Overseas delivery, on the other hand, will be shelved until later in 2012, but it will definitely make it into the global Cadillac market.
