A hotter Chevrolet Sonic sounds off for 2013 -- the Sonic RS. The new RS amplifies the Sonic's youthful style and driving experience with unique exterior and interior features matched with a turbo engine.

The 2013 Sonic RS is offered exclusively in the five-door body style. Chevrolet's exclusive MyLink infotainment system is standard. It enables navigation directions downloaded through a smart phone to be shown on the radio's large display, and offers the personalized connectivity of Pandora and Stitcher Internet radio.

The more-aggressive looking Sonic RS is available in Victory Red, Summit White, Cyber Gray Metallic and Black Granite Metallic.

One of the most-dramatic cues is the Sonic RS's front fascia, which has a deep air dam design that enhances the car's road-hugging stance. Vertical intakes at the edges of the fascia reinforce the wide, low proportion and house the fog lamps.

The 2013 Chevy Sonic RS is powered by a Ecotec 1.4L turbo engine that is rated at 138 horsepower and 148 lb.-ft. of torque. It's matched with a six-speed manual transmission or six-speed automatic.

Complementing the segment-exclusive turbocharged powertrain is MacPherson strut front suspension with coil springs and stabilizer bar, and a semi-independent, torsion beam axle-mount compound link-type rear suspension -- featuring a robust, tubular V-shape beam -- with gas-charged shocks.

The RS is the only Sonic model offered with four-wheel disc brakes, which are partnered with a four-channel anti-lock braking system. The four-sensor system incorporates electronic brake force distribution, which balances braking performance based on such factors as road conditions and the weight of passengers and/or cargo.
