Responding to a luxury car marketplace seeking smaller vehicles, Cadillac introduced the ATS as the brands new entry-level product.

The 2.5-liter boasts the best fuel economy for the Cadillac ATS with an EPA-rated travel distance of 22 miles per gallon city and 33 miles per gallon highway. Peak power for the Cadillac ATS is derived from a 320-horsepower 3.6-liter V-6 engine. A six-speed manual and six-speed automatic transmission choice is offered on the small Cadillac. The 2013 ATS offered a rear-wheel and all-wheel drivetrain choice with all three engines.
