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 321kw (430hp) and 575nm (424lb-ft) of torque with the standard exhaust system. An optional two-mode exhaust system elevates the power ratings to 325kw (436hp) and 580nm (428lb-ft).
The Grand Sport replaces the Corvette’s previous Z51 package and brings a greater degree of handling performance, with wider wheels and tyres; revised shock, stabiliser bar and spring specifications; and specific gearing. A combination of 0-60 performance of four seconds, skid pad adhesion of 1g 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 tyres in front and 325/30ZR19 tyres 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.
All of Corvette’s exterior colours are offered on the Grand Sport, and an available Heritage package adds iconic front fender hash marks offered in four colours, as well as two-tone seats with Grand Sport embroidery. The Grand Sport can be ordered with 1LT, 2LT, 3LT and 4LT trim packages, too.
