Callaway has introduced its first tuned version of the 2014 Corvette Stingray at the National Corvette Museum. Performance gains include a 10-horsepower bump to 620 from the stock version while the original 556 pound-feet of torque will be increased to somewhere north of 600. Official numbers will be released later this month once Callaway have taken their creation through final testing and validation. The Stingray’s 6.2-liter, supercharged V8 gets a three-element intercooler and a refined exhaust system that’s now even less restrictive. Style cues for the 2014 Callaway Corvette come from the C6 Corvette ZR1 as you can see the engine protruding from the hood. The Callaway upgrade to the C7 Stingray Corvette is $22,995.
