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.
