The engine is the most powerful engine to be put into a GM production sports car.

It combines the wide body from the Z06 with the standard C6 powertrain in both targa coupe and convertible models. With suspension and brake upgrades included, the Grand Sport replaces the Z51 option. A new launch control system was introduced that will allow for more optimal launch in all Corvette models. With launch control, the Grand Sport with a manual transmission is capable of a 0-60 time of four seconds flat.
