Grand Sport coupe Chevrolet Corvette LS3 6.2L engine.
The Corvette Grand Sport is available 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 430 horsepower (321 kW) and 424 lb.-ft. of torque (575 Nm) with the standard exhaust system. An optional two-mode exhaust system raises the power output to 436 horses (325 kW) and 428 lb.-ft. (580 Nm).
The 2010 Chevrolet Corvette Grand Sport which was introduced at the 12th annual C5/C6 Corvette Birthday Bash, held at the National Corvette Museum, in Bowling Green, Ky. combines the Corvette’s LS3-based powertrain with unique, wide-body styling and a racing-derived suspension.

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 1.0 g, as well as a 0.2-second improvement in 0-60 acceleration over the standard .
With its special equipment, the Corvette 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. Essentially the Grand Sport sits somewhere between the standard C6 Corvette and the Z06 Corvette for performance and comfort.
Corvette Grand Sport coupe models equipped with the manual transmission are uniquely outfitted for race track competition, too, with a dry-sump oiling system, differential cooler and a rear-mounted battery - this is the model you want to go for, otherwise you're wasting your money and may as well get the standard model.
