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. 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 rear 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.
