Corvette Grand Sport models feature wider front and rear fenders as well as a Z06-style front splitter and tall rear spoiler. Functional brake ducts and extra cooling support track-day performance.
Grand Sport models come with 18-inch front and 19-inch rear wheels. A silver-painted wheel is standard and black and chrome finishes are available. The wheels are wrapped in large 275/35ZR18 tires in front and 325/30ZR19 tires in the rear.
Also part of the package are 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, along with specific manual transmission gear ratios and a specific, 2.73 rear axle ratio on automatic-equipped models.
The 6.2L LS3 small-block V-8 is the engine in Corvette and Grand Sport models. It is rated at 430 horsepower (321 kW)* and 424 lb.-ft. of torque (575 Nm)* with the standard exhaust system. An optional dual-mode exhaust system brings a power rating increase to 436 horses (325 kW) and 428 lb.-ft. (580 Nm). A standard six-speed manual transmission and an optional six-speed automatic paddle-shift are offered.
An available Heritage package for Grand Sport models adds iconic front fender hash marks offered in four colors, and seat embroidery.
Corvette’s interior is inspired by the car’s dual-cockpit heritage. Seats that were introduced in 2012 deliver improved appearance and larger bolsters on the seat back and cushion areas to provide better driver support, especially in high-performance driving. Sueded-microfiber seat inserts are included with the leather-wrapped interior.
