Chevrolet has announced its lineup for SEMA 2013 with small cars being a big part of the bow-tie brand's showcase this year. Three Sonic models will debut in Las Vegas, the most potent of which is the Performance Sonic RS Concept, packing a 1.4-liter turbo equipped with a cold-air intake, a sport exhaust system and "Stage Kit." It also comes with a bespoke body, sport-tuned suspension, high-performance brakes and 18-inch alloys.

Debuting the new Chevy Performance package, the black and green Ricky Carmichael All-Activity Sonic also sports an aero body kit, custom rear spoiler, revised grille, and THULE roofrack. The cabin sees a flat-bottom steering wheel, short-inspired seats and aluminum gear knob. The as-yet-unseen Personalization Sonic concept, sporting a Victory Red bod color with chrome accents and graphics package, comes with a Borla exhaust, sport-tuned suspension, high-performance brakes, 18-inch alloys, and Kicker sounds system.

The smallest concept on show will be the Spark EV Tech Performance concept sporting an illuminated emblem, unique interior, billet aluminum alloys, body-color trim, and lightweight components. The concept also boasts 400 lb-ft of torque and a 7.5-second 0-60 mph sprint time. Based on the Impala TZ, the Urban Cool Impala features a grounds effect package, 20-inch alloys, leather seats and Bose sound sytem. The Sterling Silver Malibu LTZ concept comes with an aero kit, 19-inch alloys, revised 2.0-liter turbo-four unit and Borla exhaust.
