In the latest episode covering the development of the new 2013 Cadillac ATS, we see the sedan finally leaving its Nurburgring testing ground in Germany and head back to the U.S. for a debut at the 2012 Detroit Auto Show.

ATS: The Journey Chapter 4 takes us behind the scenes of Cadillac's reveal event to capture the reactions of the auto industry press as the ATS is unveiled.

Cadillac has made no secret of its desire to tackle the likes of the BMW 3-Series and Mercedes-Benz C Class in the premium sedan market. After all, the Nurburgring is the same track where Germany's automakers test most of their performance models.

The ATS ticks all the right boxes, coming with a smart-looking design, a light 3,400-pound heft, an almost perfect 50/50 weight distribution, and a MacPherson strut front suspension and sophisticated multi-link rear. However, the ATS goes further by adding a powerful and fuel-efficient engine lineup, Brembo brakes, and even adjustable magnetic-ride dampers.

We can’t wait to test the car but for now this latest video will have to suffice.
