Official: 2014 Corvette Stingray Cranks Out 460 Horsepower!

Over the last few days, we’ve been discussing the final horsepower numbers for the 2014 Corvette Stingray’s revolutionary new V8 engine. Mixed messages and leaked docs pointed to that number being 455 HP, and it turns out that’s correct, however, GM today finally made it official by saying the new Stingray Coupe actually makes more than that when equipped with the optional performance exhaust.

With the optional performance exhaust, the 2014 Corvette Stingray Coupe is SAE-certified at 460 horsepower at 6,000 rpm and 465 lb-ft torque at 4,600 rpm. With the standard exhaust system, the Corvette Stingray is SAE-certified at 455 horsepower and 460 lb-ft of torque. These are the highest standard power ratings ever for the Corvette which is expected to have a highway fuel economy that is better than the current 2013 Corvette’s 26 mpg.

“The 2014 Corvette Stingray’s LT1 engine is a triumph of advanced technology, delivering more power and torque than ever before with greater efficiency,” said Jordan Lee, Small Block chief engineer.

“The LT1′s performance complements the Corvette’s low mass with a tremendous feeling of power that builds as the rpm climbs. Drivers will experience more power and acceleration than ever before with the standard engine – in fact, its power and torque surpass many uplevel engines offered by competitors.”

Chevy says that LT1 has greater power density than the C6 Corvette’s LS3 engine and the Z06 Corvette’s LS7. The LT1 produces comparable torque to the LS7 up to 4,700 rpm and its peak torque is within 5 lb-ft of the 7.0L engine. 90 percent of the LT1′s peak torque can be found in the 3,000 to 5,500 rpm band which offers the 2014 Corvette Stingray quick acceleration at a wide speed range.

The LT1′s high output and high power density and efficiency are due to several advanced technologies found on the 5th generation small block. Direct injection ensures a more complete burn of the fuel. Active Fuel Management helps save fuel by shutting down half of the LT1′s cylinders in light-load driving. Continuous Variable Valve Timing helps to further optimize performance, efficiency and emissions.

Although Chevrolet has come out with the official new horsepower and torque numbers, we’re still waiting on the EPA Fuel Economy ratings which as mentioned before, should be higher than the current 26 mpg highway that the current LS3 engine produces in the 2013 Corvette.
