Despite the fact that General Motors has already pulled the wraps off of the highly anticipated Chevrolet C7 Corvette Stingray – in both coupe and convertible forms – there's still a lot we don't know about The General's new halo car. When it first launched, GM stated that the 'Vette's new 6.2-liter LT1 V8 would put out an estimated 450 horsepower and 450 pound-feet of torque. But some PDF scans found by the folks at the Corvette7 forum site show that the Stingray coupe might actually throw down 455 hp and 460 lb-ft – increases of 5 hp and 10 lb-ft over the original numbers, and gains of 25 hp and 36 lb-ft versus the current car's 6.2-liter LS3 V8.

If these PDF scans are to be believed, it looks like only the coupe will benefit from this slightly more powerful setup, as a similar spec list for the Corvette Stingray Convertible states that the droptop will make 450 hp and 450 lb-ft – spot on with the original estimates. Official fuel economy numbers are still unknown, though GM has previously stated that the 'Vette is "expected to improve" upon the current car's EPA highway rating of 26 miles per gallon.

We expect the officially official numbers to be revealed later this year, closer to the Corvette's launch. Head over to Corvette7 to read more, and check out the PDF scans for yourself in the gallery below.
