Chevrolet Corvette GS (Grand Sport)

Beginning with the 2010 model year, Chevrolet reintroduced the Corvette Grand Sport, a nameplate that was last used in 1996. The car combines the Corvette's LS3-based powertrain with unique, wide-body styling and racing-bred suspension. The model replaces the Z51 from previous model years.

The car is offered in both coupe and convertible body styles, with either a six-speed manual or six-speed automatic transmission. The LS3 6.2-liter engine is rated at 430 horsepower and 424 pound-feet of torque with the standard exhaust system. An optional two-mode exhaust system elevates the power ratings to 436 hp and 428 lb-ft.

Compared with the Z51 trim level it replaces, the Grand Sport delivers better handling, with wider wheels and tires; revised shock, stabilizer bar and spring specifications; and specific gearing. The equipment enables cornering capability of 1.0 g, as well as a 0.2-second improvement in zero to 60 mph acceleration versus standard LS3-powered models.

Other highlights include 18- and 19-inch wheels, a Z06-style splitter and spoiler, functional brake ducts, and Z06-size brakes, including 14-inch front rotors with six-piston calipers and 13.4-inch rear rotors with four-piston calipers.

All of Corvette's exterior colors are offered on the Grand Sport, and an available Heritage package adds front fender hash marks offered in four colors, 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.

Pricing for the 2010 Corvette Grand Sport Coupe starts at $55,720, with the convertible version listing from $59,530. Although that pricing represents a $5,360 to $6,205 price premium over the base car, the Grand Sport package is still a relative bargain. Considering the package replaces the $1,695 Z51 option, Grand Sport buyers will only be forking over an extra $3,665 to $4,510 for a new wide-body package, Z06 brakes, an improved suspension and all around better performance.
