The Cobalt ss Supercharged builds upon the expressive design and dynamic driving experience of the Cobalt Coupe and Coupe ss. The Cobalt was created on a strong foundation. The rigid lower-dominant body structure is engineered as a single unit for mass efficiency and stiffness. The underbody uses high-strength steel as welded members in strategic locations for maximum strength, structural integrity, mass optimization and crashworthiness.

Cobalt ss Supercharged features a strut-type front suspension, semi-independent torsion beam rear suspension, and increased diameter front and rear stabilizer bars with tuned suspension bushings. In addition, the chassis and springs were stiffened, the spring rates and damping were specially tuned and the shock strut valving was modified for a responsive, sport suspension feel. The monotube rear shocks with 33-millimeter pistons are larger in diameter than those found on standard Cobalts. The coupe's ride height also has been reduced by 10 millimeters. The electric power steering also is tuned for increased driver feedback.

Cobalt ss Supercharged features four-wheel anti-lock disc brakes. The front disc rotors are 11.6 inches in diameter, which is approximately 1 inch larger than the rotors on standard Cobalt models. The rear drum brakes standard in other Cobalts were also replaced with disc brakes with 10.6-inch rotors. They are mounted on an all-new rear axle assembly that incorporates revised suspension geometry. The ss Supercharged features larger, five-bolt wheel hubs, brake calipers and brake pads. The larger calipers and brake pads allow greater braking capacity and are proven performance parts found in other high-performance GM vehicles.

The Ecotec 2.0L SC is mated to a five-speed manual transmission. The 240-millimeter clutch assembly is larger on the 2.0-liter supercharged I-4 than the other Naturally Aspirated Ecotecs. The five-speed has close-ratio gearing that is tailored to the power band of the 2.0-liter engine. To improve acceleration the final drive ratio is also shorter at 4.05:1. A short-throw shifter quickens the shifts and provides a more positive feel as well. The shifter's travel is approximately 1 inch shorter than the shifter found in standard Cobalt models. Equal length transmission half shafts are also utilized to address torque steer in this front-drive car.

The exterior styling of the Cobalt ss Supercharged complements the performance aspects of the car. The front fascia features a large, deep air inlet and the rear fascia has a cutout for the large, chromed exhaust tip. Along with revised rocker moldings, the enhanced bodywork of the ss Supercharged visually lowers the coupe 1 inch. Halogen fog lamps are also included. The Cobalt Supercharged ss comes standard with a unique, aggressive rear decklid spoiler. The coupe will offer five exterior body colors including Rally Yellow, Black, Orange Metallic, Victory Red and Arrival Blue Metallic.

The interior was also modified to complement the performance characteristics of the Cobalt ss Supercharged Coupe. The accelerator pedal was redesigned to enable heel-and-toe driving to improve driver feedback and response. The interior also features titanium-faced speedometer, tachometer and gauges in the instrument cluster, and an A pillar-mounted boost gauge to monitor Supercharger performance.
