We got an in-depth look at some of GM’s current, future and concept vehicles while attending the 2012 North American International Auto Show. We’ve collected some of our favorite photos from the three-day event above, including shots of the 2013 Cadillac ATS, the 2013 Chevy Sonic RS and the 2013 Buick Encore. To read more about the event, check out our 2012 NAIAS recap.

GM unveiled the 2013 Sonic RS with a lower and stiffer suspension, 4-wheel disc brakes and chrome tips. Also included are 17 inch wheels and a new front facia for a tough-looking interior. Additionally, the Sonic RS features a 138-horsepower (103 kW) Ecotec 1.4L turbo engine — the only vehicle in its segment to offer a turbocharged powertrain.

The Sonic RS has a great look and should add more sales to the Chevy brand. We’re very impressed in the way Chevy is targeting a younger audience with cutting edge designs at competitive prices. It will be released to the public in summer-fall 2012.
