In case you may have forgotten, the 2013 Cadillac ATS is offered with three different powerplants, beginning with an all-new 2.0-liter turbocharged four-cylinder with 270hp. A second 2.0-liter four banger, the 2.0T with 135hp, will be offered in Europe and it's one of the most power-dense engines in the industry. The base engine for North America is a 2.5-liter naturally-aspirated inline-four with 200hp which GM claims is capable of 30 mpg on the highway. The ad will run on February 5th during the Super Bowl.
