In what has been called "probably the most important car Cadillac has ever done," by GM North America President Mark Reuss, the luxury car company is taking their 2013 ATS to the Nurburgring
-Nordschleife in Germany for testing. Labeled by Jackie Stewart as 'the Green
Hell,' the General Motors subsidiary could think of no better place to run their latest model ragged during its prototype phase than the famed German racetrack. Cadillac believes that the new ATS luxury sport sedan wil rival the BMW 3-Series.
