2017 Corvette Grand Sport Has Racing Roots
A ‘purist’ model that leverages a half-century legacy of motorsports success
Like the 2015 Le Mans-winning Corvette C7.R GTE Pro race car, the new Grand Sport combines a lightweight architecture, a track-honed aerodynamics package, Michelin tires and a naturally aspirated engine.
The 2017 Corvette Grand Sport offers an estimated 1.05g in cornering capability – and up to 1.2g with the available Z07 package.
Heritage-inspired design cues and exclusive features acknowledge the historic Grand Sport legacy, established in 1963 to take on the world’s best sports cars. Only five were built before a corporate decision suspending direct motorsports involvement ended the project.
No holding back
Engineers adapted the chassis tuning, upgraded cooling systems, and performance technologies of the Corvette Z06 to give the new Grand Sport capability commensurate with its racing-derived history.
The result is a potent track car. In fact, the Grand Sport with the Z07 package is less than one second off the track record for the previous-generation Corvette ZR1 on the road course at GM’s Milford Proving Ground.
Content highlights for Grand Sport include:
- Michelin Pilot Super Sport summer tires: 285/30ZR19 (front) and 335/25ZR20 (rear)
- Specific Grand Sport wheel design: 19x10 inches (front) and 20x12 inches (rear)
- Brembo brake system with (355 mm) 14-inch rotors and six-piston calipers in front and (340 mm) 13.4 inch rotors and four-piston calipers in the rear
- Standard magnetic ride control, specific stabilizer bars and unique springs
- Standard electronic limited-slip differential
- LT1 V8 engine rated at (343 kW) 460 hp, with dry-sump oiling system and active exhaust
- Seven-speed manual transmission with active rev match and available eight-speed paddle-shift automatic with specific performance calibration
- Available Z07 package adds carbon ceramic-matrix brakes and Michelin Pilot Sport 2 Cup tires.
In addition to track-focused aero elements, the Grand Sport also features specific front fender inserts, a Z06-style grille and wider rear fenders – a distinctive design package that gives the car a track-ready attitude.
Grand Sport models are offered with the Stingray’s full exterior and interior color palette. An available Heritage package includes hash-mark fender graphics in six colors, with the hash-mark detail carried onto the interior’s brushed aluminum trim. Full-length stripes are also offered.
Grand Sport Collector Edition
The Grand Sport Collector Edition features an exclusive Watkins Glen Gray Metallic exterior with Tension Blue hash-mark graphics, satin black full-length stripes, black wheels and a unique Tension Blue full leather and suede-wrapped interior.
The Tension Blue color is a bold, modern take on the hue historically associated with the Grand Sport. Inside, a three-dimensional representation of an original Grand Sport race car is embossed in the headrests and that shape is also used on an instrument panel plaque that carries a unique build sequence number.
The Collector Edition will be offered later in the model year in the U.S. and Europe.
