When the ATS was revealed, the Detroit Free Press said it "shocked the auto industry," and now it has been named their 2013 Car of the Year.

Car of the Year: Cadillac ATS

The ATS sport sedan is a watershed vehicle for Cadillac and a breakthrough that will change the way General Motors develops all its upcoming vehicles.
The engineers who developed the ATS at GM's Warren Tech Center were focused like a laser on the BMW 3-series, the compact that's widely considered the world's best sport sedan.
It was the first time GM had the confidence to tackle the 3-series head on. The CTS that re-established Cadillac as a competitor for the likes of Audi, BMW, Lexus and Mercedes-Benz tried to outflank the 3-series: it was nearly the size of the larger 5-series, but priced like the compact 3-series.
