Chevrolet Corvette Grand Sport

Grand Sport is one of the most storied monikers in Corvette’s illustrious racing heritage. For 2010, it once again becomes part of the Corvette’s lineup, available in coupe and convertible models.

The new Grand Sport combines the Corvette’s LS3-based powertrain with wide-body styling, a wider track and a racing-bred suspension for a distinctive model that delivers a great balance of road and race track performance. It is offered 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 elevates the power ratings to 436 horses (325 kW) and 428 lb.-ft. (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. A combination of 0-60 performance of four seconds, skid pad adhesion of 1 g and EPA-estimated 26 mpg on the highway makes it a very well-rounded sports car.

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.

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.
