Offered in rear- or all-wheel drive, the ATS is an all-new compact sports sedan. Three engines are offered: a 2.5-liter four-cylinder, a 3.6-liter V6, and a new 2.0-liter turbocharged four-cylinder. Transmission choices are six-speed manual or automatic. AWD is optional with the more powerful engines. It offers nimble and capable handling, a host of luxury, convenience, and technological features. It has Cadillac's new CUE infotainment system, which uses flush touch-sensitive buttons and voice commands for the audio and navigation systems. Inside is a snug, but well finished interior.
