Corvette coupe, convertible, Z06 and ZR1 (limited availability) have steadily grown in stature amid the world hierarchy of performance automobiles. Now, two NEW models join the stable for 2010 - Grand Sport Coupe and Convertible. Inspired by the iconic racing Sting Rays of the 1960s, the GS include a winder track, aggressive dampers and springs, larger stabilizer bars, and much more. Corvette coupe, convertible and Grand Sport are all powered by a 6.2 Liter V8 engine that delivers 430 hp and offers an EPA estimated 26 MPG highway, all with no gas-guzzler tax.
