General Motors Co. said Tuesday that its all-new LT1 6.2-liter V-8 engine offering in the 2014 Chevrolet Corvette Stingray has been certified at 460 horsepower and 465 foot-pounds of torque  an increase of 24 horsepower and 37 foot-pounds of torque over today's LS3 6.2-liter V-8  when using a performance exhaust system.

The engine is certified at 455 horsepower and 460 foot-pounds of torque with a standard exhaust. That's up by 25 horsepower and 36 foot-pounds of torque over the LS3 engine. Chevy said both ratings are the highest standard power ever for the Corvette, which is expected to top 26 miles per gallon on the highway.

"The 2014 Corvette Stingray's LT1 engine is a triumph of advanced technology, delivering more power and torque than ever before with greater efficiency," Jordan Lee, GM's small-block engine chief, said in a statement. "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."
