Chevrolet has unveiled the Sonic Super 4 at the 2011 SEMA Show. The vehicle is a race car concept that demonstrates Chevrolet's new small car performance potential. The Sonic Super 4 joins other Chevy performance cars this week in the Chevrolet display at the SEMA Show.

"This is an exciting example of Chevrolet's small-car performance capability,", commented Jim Campbell, U.S. vice president, Performance Vehicles and Motorsports.

"Sonic has the soul and specifications to be a winner.", he added.

Sonic measures 2 525 mm – wheelbase, 1 509 mm - front and rear tracks. Its body-frame-integral structure ranks among the stiffest in the global small-car segment, with some of the steel in it delivering tensile strength of 145 000 psi (1 000 MPa) or higher.

The Sonic Super 4 concept features a suspension modified for racing and a lower restriction intake and exhaust system to provide enhanced on-track performance. The interior comes with a chrome moly roll cage built to SCCA specifications, as well as other safety equipment. It looks the part, too, with a lowered stance and 18" racing wheels and tires. It also wears Chevrolet Z-Spec concept accessories, including ground effects and a high-wing spoiler.
