Chevrolet Performance worked over the Chevrolet Sonic just for this year's SEMA show to create this B-Spec racecar concept. Built to conform to all of rules and regulations of the B-Spec subcompact classes in both the SCCA and the Grand-Am series, the five-door features new coilovers on all four corners with revised mounts, adjustable front stabilizer bar links and a rear axle shim kit. The requisite air inlet restrictor has also been shoved in place, and the ECM and EBCM have been recalibrated accordingly. That's exciting in all, but we're more thrilled about the fact that Chevrolet says the parts are intended for production as a kit any consumer can buy.

That would leave competitors to independently source pricey pieces like the roll cage, seat and associated harnesses. The automaker says some of the parts may change en route to production, including the lightweight 15-inch alloy wheels.

Underhood, buyers can expect to find a stock 1.8-liter four-cylinder mated to a factory five-speed manual gearbox. Look for the production kit to go on sale in the first quarter of 2013. Check the full press blast below for more information.

Chevrolet Enters B-Spec Competition with Sonic Race Car

Concept previews production-intended package for subcompact racing series

DETROIT – Acclaimed for its balanced handling and sporty driving experience, Chevrolet Sonic has been transformed by Chevrolet Performance for the track as a B-Spec race car concept. It previews a competition kit for racers to help them convert a street-going Sonic into a dedicated race car.

"Sonic B-Spec concept demonstrates the car's capabilities in the increasingly popular B-Spec subcompact classes in SCCA and Grand Am series," said Jim Campbell, GM U.S. vice president of Performance Vehicles and Motorsports. "Sonic's great balance of power and responsive handling make it a natural on the track – and a formidable competitor."

Conforming to series guidelines, the Sonic B-Spec concept's modifications are limited to safety features and chassis/suspension enhancements designed for the rigors of racing. Components of the production-intended competition kit on the concept include chassis, suspension and other parts required to transform a production Sonic into a competitive race car:

Front strut coil-over assemblies and mounts
Rear shock coil-over assemblies and mounts
Adjustable front stabilizer bar links
Rear axle shim kit
Inlet air restrictor
Recalibrated ECM and EBCM.

The Luxor Blue concept vehicle – accented with Monaco Blue graphics – also shows lightweight 15x7-inch racing wheels wrapped with complementing racing tires. Chevrolet is still evaluating the components of the kit, so some of the parts may change for production.

Safety features, such as the roll cage, safety seat, window net and racing harnesses, would be sourced separately by the builder. The concept vehicle is shown with a Monaco Blue-painted roll cage, carbon fiber racing seat, five-point safety harness, window safety net, center catch net, quick-release steering wheel/hub system and a fire extinguisher.

Like the other vehicles in B-Spec classes, the Sonic race car concept's 1.8L engine remains unchanged from its factory specifications, although an air restrictor is employed to equalize its output with other competitors. It is backed by the production five-speed manual transmission.

The Sonic B-Spec competition kit is anticipated to go on sale in the first quarter of 2013 through Chevrolet Performance retailers.

The 2013 Chevrolet Sonic is one of the segment's best sellers and is positioned between the all-new Spark and the popular Cruze to round out Chevy's small car portfolio. As the only subcompact built in America, Sonic comes with segment-leading 10 standard air bags and leads in interior roominess. The performance-inspired Sonic RS hits dealerships in late 2012 and features Chevrolet's exclusive infotainment system MyLink , with a seven-inch color touch screen radio capable of displaying smartphone-based music, videos, photos and contacts for hands-free calling.
