Base models get a 200-horsepower, 2.5-liter four-cylinder engine with direct injection. A 270-hp, turbo 2.0-liter four-cylinder will be optional, as will Cadillac's familiar 318-hp, 3.6-liter V-6. All three engines can run on regular gas, though Cadillac recommends premium with the turbo. All-wheel drive is optional across the board. The ATS comes with a six-speed automatic, and a six-speed manual will be available in certain configurations.

GM took to Germany's Nurburgring track to develop the ATS. Cadillac says the chassis sports near-50/50 weight distribution and a multilink rear suspension. Brembo-brand brakes are optional, as is a limited-slip rear differential and sport-tuned adaptive suspension.
