2012 SEMA: Chevy Sonic B-Spec Race Car [Live Photos]
“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.”
B-Spec racing rules dictates that the mods have to be limited to the safety features and chassis/suspension enhancements designed for the rigors of racing, so the engine has to be left untouched.
But the Sonic packs some interesting hardware: 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 race car is finished in Luxor Blue and comes with lightweight 15x7-inch racing wheels wrapped with complementing racing tires. This is still a concept, and Chevy engineers are still evaluating the specific parts before it puts the Sonic B-Spec racer into production
