It’s official! Chevrolet has announced the return of the Corvette Grand Sport for the 2010 model year at the 12th annual C5/C6 Corvette Birthday Bash at the National Corvette Museum, in Bowling Green, Ky. The new Corvette Grand Sport features the LS3-based powertrain with distinct, wide-body styling and a racetrack-bred suspension.
Pricing for the brand new 2010 Corvette Grand Sport has been announced, and the coupe comes with a $55,720 tag while the Grand Sport Convertible has a $59,530 sticker price. Destination fee for both models is $950.
Available in either coupe or convertible body styles, the new Corvette Grand Sport comes with either a six-speed manual or six-speed automatic transmission.
Powering the Grand Sport is a LS3 6.2L engine that provides 430 hp (321 kW) of output and 424 lb.-ft. of torque (575 Nm) with the standard exhaust system. When an optional two-mode exhaust system is installed, the engine could provide up to 436 hp (325 kW) of output and 428 lb.-ft. (580 Nm) of torque. Replacing the Corvette's Z51 package, the Grand Sport comes with better handling performance, thanks to wider wheels and tires; revised shock, stabilizer bar and spring specifications and specific gearing.
These specs allow the Grand Sport to improve its cornering capability to 1.0 g and improve its zero-to-sixty acceleration by 0.2 seconds. Grand Sport coupe models fitted with the manual transmission are well-geared for racetrack competition, thanks to specs like a dry-sump oiling system, differential cooler and a rear-mounted battery.
Additional features for the Grand Sport includes wider front and rear fenders, including front fenders with integrated Grand Sport badges; Z06-style front splitter and tall rear spoiler; and functional brake ducts and extra cooling. Also featured are distinct 18-inch front and 19-inch wheels; 275/35ZR18 tires (front) and 325/30ZR19 tires (rear); Z06-size brakes, including 14-inch (355 mm) front rotors with six-piston calipers as well as 13.4-inch (340 mm) rear rotors with four-piston calipers.
Completing its special equipment are specific manual transmission gear ratios and specific rear axle ratio on automatic-fitted models. The Grand Sport’s suspension package is similar to that of the Z06, but with the addition of a removable roof on coupes and the availability of a convertible body style.
Likewise, Chevrolet offers a paddle-shift six-speed automatic transmission for the Grand Sport. All exterior colors on Corvette’s palette can be used on the Grand Sport. When customers avail of the Heritage package, they can avail of iconic front fender hash marks in four colors and two-tone seats with Grand Sport embroidery. Chevrolet also offers the Grand Sport in 1LT, 2LT, 3LT and 4LT trim packages.
