Callaway's modified C8 Corvette is going to be epic. Earlier this year, Callaway Cars unveiled the Chevrolet Silverado Signature Edition, a supercharged version of the full-size pickup with a boosted output of 420 horsepower and 460 lb-ft of torque. The specialty vehicle manufacturer specializes in building high-performance versions of General Motors cars and is best known for its modified Corvettes like the legendary Callaway Twin Turbo Corvette. With this in mind, we've been wondering when the new Chevrolet Corvette Stingray will get the Callaway treatment. Speaking with Autoweek, company founder Reeves Callaway confirmed that Callaway has big plans for the C8 Corvette, but it's going to be a long time before we get to see the fruits of its labor.
