Upon release, Chevy claimed the 2014 Corvette would offer an estimated 450 horsepower and 450 pound-feet of torque. It appears that was a moderately conservative estimate, as PDF files that appear to show the final figures, via the Corvette7 forum, reveal the coupe will pack 455 horsepower and 460 pound-feet of torque.
The Corvette Stingray Convertible is also shown in a document at Corvette7, but it still has the estimated 450/450 figures. It's likely that the engine will be rated the same in both Coupe and Convertible forms of the Stingray, however.
