You can put this under the ‘another Caddy ATS teaser’ category. Apparently Cadillac ATS development team is spending a lot of time down at the Nurburgring fine-tuning their sporty mid-size sedan in preparation for 2013 launch. Cadillac was the last brand you would expect to catch the ‘Ring fever. But they have, pretty severely! We just hope they don’t forget Cadillacs are more about luxury, comfort and style than speed and handling.
