Bowling Green, Kentucky – Chevrolet has announced the new 2010 Corvette Grand Sport, combining the LS3-based powertrain with unique, wide-body styling and racetrack-bred suspension. The new model was introduced at the 12th annual C5/C6 Corvette Birthday Bash at the National Corvette Museum in Bowling Green, Kentucky.

The Grand Sport will be available in both coupe and convertible body style, with six-speed manual or six-speed automatic transmission. The 6.2-litre engine is rated at 430 horsepower and 424 lb-ft of torque with the standard exhaust system, and 436 horsepower and 428 lb-ft with an optional two-mode exhaust system.

The Grand Sport replaces Corvette’s previous Z51 package and includes wider wheels and tires, revised shock, stabilizer bar and spring specifications, and specific gearing. When fitted with a manual transmission, the coupe includes a dry-sump oiling system, differential cooler and rear-mounted battery.

The new model’s suspension package approaches that of the Z06, but includes a removable roof on the coupe to the Z06 model’s fixed roof, available convertible body style, and available paddle-shift six-speed automatic transmission, to the Z06 model’s manual-only. An available Heritage package adds front fender hash marks, and two-tone seats with Grand Sport embroidery.

The Grand Sport was originally envisioned by Corvette engineer Zora Arkus-Duntov as a factory-built, race-ready production model. The planned 125 production models required for racing-class homologation were never built, but five prototypes based on the 1963 Corvette’s styling were hand-assembled and saw extensive racing experience in the hands of private owners. Chevrolet offered 1,000  limited-edition Grand Sport production models in 1996, commemorating the original racing cars and marking the end of the C4 era in Corvette production.
