The Callaway Corvette SC620 was a variant of the C6 Callaway Corvette that was introduced for the 2013 model year. Largely a tuning package, the SC620 was crafted using a C6 Grand Sport as a base, and featured a number of upgrades. The most notable upgrade was the addition of a supercharger, which saw output rise to 620hp. Only one Corvette is believed to have been fitted with the SC620 package.
