2012 Corvette Grand Sport right hand drive

2012 Corvette Grand Sport ConvertibleThe 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 greater degree of handling performance, with wider wheels and tires; revised shock, stabiliser bar and spring specifications; and specific gearing.

Zero-60 performance of four seconds, skid pad adhesion of 1g and an EPA-estimated 26 mpg on the highway make for a rare combination of performance, handling and efficiency.

Grand Sport coupe models equipped with the manual transmission are uniquely outfitted for track events, too, with a dry-sump oiling system, differential cooler and a rear-mounted battery. Magnetic Ride Control is available and with manual-transmission models, includes Goodyear F1 Supercar Gen 2 tyres.

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
  • Eighteen-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.

2011 Corvette Grand Sport right hand drive interiorWith 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.
