The Grand Sport is all about lightness and cornering. Chevy calls it "A pure expression of the car’s motorsports-bred pedigree." This track-'Vette starts off with the LT1 V8 engine rated at (343 kW) 460 hp, with dry-sump oiling system and active exhaust. Both the rev-matching 7-speed stick and 8-speed paddle shifting automatic are available, and the auto has a Grand Sport-specific calibration. For the first time, the Grand Sport can also be combined with the Z07 package. When set up this way, the car can corner at up to 1.2gs. Chevy says that the new Grand Sport with Z07 package is within a fraction of a second of the prior ZR1's time around the Milford Proving Ground.
Here are the highlights of the package:
◾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
◾Front Fender Inserts, Z06 Grill, Widened Rear Fenders
◾Optional Grand Sport Collector Edition features an exclusive Watkins Glen Gray Metallic exterior with Tension Blue hash-mark graphics
◾Available Z07 package adds carbon ceramic-matrix brakes and Michelin Pilot Sport 2 Cup tires.
The Grand Sport will be on sale this summer in the U.S. and the Grand Sport Collector Edition in the fall. Chevy plans to offer the Grand Sport in Europe as well about three months behind the U.S. inventory allocations.
