Offered in rear- or all-wheel drive, the ATS has nimble, capable handling and sharp steering that makes it a treat to drive. The 2.0-liter turbo is quick, but it doesn't feel all that powerful and got just 23 mpg overall when we tested it with the old six-speed automatic, which has been supplanted by a better eight-speed unit. A smooth, refined 3.6-liter V6 is also available. The ride is taut, and braking is excellent. However, the Cue infotainment system, with its flush buttons, is very convoluted and frustrating to use. The interior is well-finished but very snug, particularly in the back. The high-performance ATS-V gets a 464-hp twin-turbo V6, and a two-door coupe is also available. Reliability has remained well below average.
