The Sonic Performance concept packs a bigger punch thank its regular-production counterpart thanks to modifications such as a cold-air induction system and a free-flowing exhaust line. Precisely how much power the Sonic gains was not specified, but Chevrolet promises a stiffer, track-tuned suspension that noticeably lowers the ride height helps the driver make the most of the extra ponies.
Visually, the Sonic Performance concept boasts an eye-catching Synergy Green paint job with contrasting white racing stripes, 17-inch alloy wheels painted white and a body kit consisting of a deeper front bumper, side skirts and an air diffuser integrated into the rear bumper.
The Bowtie’s second Sonic-based show car is called Sonic Accessories concept. Designed to showcase the range of dealer-installed accessories that every Sonic can be ordered with, the hatchback features black alloy wheels, white rings around the headlights, a two-tone black and white paint job and a number of gloss black components including the radiator grille surround, the mirror caps and the roof-mounted spoiler. A Kicker sound system adds a finishing touch to the concept.
Chevrolet has not made any mechanical modifications to the Sonic Accessories, meaning it is powered by a stock 1.4-liter four-cylinder engine that makes 138 horsepower and 148 lb-ft. of torque.
Finally, the Cruze RS Plus concept builds on the regular-production 2015 Cruze RS with a Wildfire Metallic exterior paint job, a body kit all around and a discreet trunk-mounted spoiler. The 1.4-liter is fitted with a performance-enhancing stage kit but Chevrolet is keeping technical details and performance figures under wraps until the start of the SEMA show.
Chevrolet’s SEMA-bound concepts aren’t necessarily headed to production as-is, but the bulk of the accessories they feature can already be ordered through Chevrolet dealers.
