The 2017 Grand Sport’s lightweight architecture, downforce-producing aerodynamics package, enhanced cooling package, electronic limited-slip differential and Michelin Pilot Super Sport tyres combine to offer a Chevrolet-estimated 1.05g in cornering capability, and up to 1.2g with the available Z07 package, which includes Pilot Sport Cup 2 tires.
The new Corvette Grand Sport also offers estimated 0 – 100 km/h sprint in 3.8 seconds (0-60-mph in 3.6 seconds), with the available Z07 performance package and available paddle-shift eight-speed automatic transmission. A seven-speed manual with Active Rev Match is standard.
Further, engineers adapted the Brembo braking system from the Corvette Z06 to give it estimated 60-0-mph performance of less than 100 feet with the available Z07 package, which adds carbon ceramic-matrix brake rotors, along the PS Cup 2 tyres.
In addition to the track-focused chassis and suspension components, the Grand Sport features unique exterior elements, including specific front fender inserts and Z06-style grille, as well as wider fenders and rear quarter panels to accommodate a wider track.
Grand Sport models are offered with the Stingray’s full exterior and interior color palette, including 10 exterior colors: Admiral Blue Metallic, Watkins Glen Gray Metallic, Black Rose Metallic, Sterling Blue Metallic, Long Beach Red Metallic Tintcoat, Arctic White, Blade Silver Metallic, Black, Corvette Racing Yellow Tintcoat and Torch Red.
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 in five colors. They are joined by the available Z07 package, five wheel choices and available carbon fiber ground effects to offer a wide and diverse range of customizable choices.
A Grand Sport Collector Edition will be offered later in the model year, featuring 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. 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 2017 Corvette Grand Sport is priced at $66,445 for the coupe and $70,445 for the convertible. Roll-out to dealerships is expected at the end of June.
