Grand Sport, it’s one of the most storied names in the Chevrolet Corvette’s illustrious racing heritage and it is returning to the lineup.

Chevrolet announced the new, 2010 Corvette Grand Sport at the 12th annual C5/C6 Corvette Birthday Bash, held at the National Corvette Museum, in Bowling Green, Kentucky in the good old US of A.

The new Grand Sport model combines the Corvette’s LS3-based powertrain with unique, wide-body styling and a racetrack-bred suspension for a distinctive, starting grid-ready performer.

It is offered in both coupe and convertible body styles, with either a six-speed manual or six-speed automatic transmission.

The LS3 6.2L engine is rated at 321kW and 575Nm with the standard exhaust system. An optional two-mode exhaust system elevates the power ratings to 325kW and 580 Nm.

The Grand Sport replaces the Corvette’s previous Z51 package and brings a greater degree of handling performance, with wider wheels and tires; revised shock, stabilizer bar and spring specifications and specific gearing.

The equipment enables cornering capability of 1.0g, as well as a 0.2-second improvement in 0-100km/h acceleration vs. standard LS3-powered models.

Grand Sport coupe models equipped with the manual transmission are uniquely outfitted for racetrack competition, too, with a dry-sump oiling system, differential cooler and a rear-mounted battery.

The complete list of content and special features for the Grand Sport includes
• Wider front and rear fenders – including specific front fenders with integrated Grand Sport badges
• Z06-style front splitter and tall rear spoiler
• Functional brake ducts and extra cooling
• Unique 18-inch front and 19-inch wheels; painted finish standard and chrome finish optional
• Large 275/35ZR18 tires in front and 325/30ZR19 tires in the rear
• Z06-size brakes, including 14-inch (355 mm) front rotors with six-piston calipers and 13.4-inch (340 mm) rear rotors with four-piston calipers
• Specific manual transmission gear ratios
• Specific rear axle ratio on automatic-equipped models

With its special equipment, the Grand Sport offers a unique blend of performance and amenities. Its suspension package approaches that of the Z06, but includes a removable roof on coupes (Z06 has a fixed roof) and, of course, the availability of a convertible body style.

Also, the paddle-shift six-speed automatic transmission is offered, while a manual transmission is the only choice with the Z06.
