Sounds like some possible good new stuff being shown for the Sonic. Per Motortrend: On the Sonic Performance concept, Chevrolet went all out. Not just on the exterior -- which is adorned in Synergy Green paint and a white stripe -- but also under the hood. A track-tuned suspension lowers the ride height for a sportier stance, while its 1.4-liter turbo I-4 engine comes with cold air-induction and high-flow exhaust systems to produce more power. Along with white 17-inch aluminum wheels, the car also features Chevy Accessories like white headlamp rings, grille surround, and rear spoiler.A Sonic Accessories concept looks remarkably like the Sonic Performance model, except with a white and black color scheme. A white exterior mixes with a black stripe, black 17-inch wheels, black grille surround and rear spoiler, and a suspension kit. A Kicker subwoofer and amplifier is an unexpected surprise on the inside.
