The 2010 Chevrolet Corvette Grand Sport was sold new to Callaway, which turned it into a supercharged SC606.
While retaining its original engine and bottom end, the car has covered more than 300,000 miles.
This C6 originally served as a marketing car and was also used for research and development at Callaway.
Chevrolet launched the C6 version of the Corvette Grand Sport back in 2010. Noted 'Vette tuner Callaway snatched an early build off the assembly line to develop a modified version of its own. Dubbed the SC606, Callaway bolted an Eaton supercharger atop the mighty LS3 V8. As the name indicates, horsepower was rated at 606, which is quite the jump over the stock Grand Sport's 430 horsepower.
Callaway Cars did more than just slap in the go-fast bits, however, as these cars were engineered to last. There's clear proof of that too, since the original development and marketing SC606 just passed 300,000 miles—all on its original engine.
