The 2010 Corvette Grand Sport range has been unveiled. It features the 6.2-litre LS3 engine with either 430bhp or 436bph. Two models, a Coupe and a Convertible will be sold.
Corvette is reintroducing the Grand Sport badge to its lineup. The new 2010 Corvette Grand Sport is based on the LS3 powertrain with wide-body styling. It features a racetrack-bred suspension for greater performance enjoyment. The two-door sports car comes in either Grand Sport Coupe or Convertible versions. The latter has a removable roof. The Grand Sport replaces the Corvette's previous Z51 package.
Feeding power to the rear wheels is the LS3 6.2-litre cast aluminium V8 that delivers 430bhp (321kW) and 424 lb.-ft (575Nm) of torque. These figures are obtained with the standard exhaust system. Fitting an optional two-mode exhaust system hikes power up to 436bhp (325kW) and torque rises to 428 lb.-ft. (580Nm). The 0 - 60mph time is said to have improved by 0.2 seconds over other LS3-powered models.
Customers will be able to choose between a 6-speed manual and a 6-speed automatic transmission. There are also four different trim levels to pick from. Different sized tyres of 275/35ZR18 at the front and 325/30ZR19 at the rear wrap around 18-inch front and 19-inch rear wheels respectively. Electronic traction control and ABS come standard.
Exterior colours are identical to those offered in the normal Corvettes. Moreover a Heritage package is available for the Grand Sport which consists of two-tone seats with Grand Sport embroidery and front fender hash marks that come in four colours.
Grand Sport is a name that came out in 1963 as a badge put on factory-built, lightweight and race-ready production cars. These were never officially backed by GM but were nevertheless raced by privateers throughout the 1960s.
