It's official. Chevrolet has just announced that its all-new 2014 Corvette Stingray with the LT1 6.2L V8 engine will produce a whopping 460 horsepower and 465 lb-ft of torque at 4,600 rpm with the available performance exhaust system. Corvettes equipped with the standard exhaust system are SAE-certified at 455 horsepower and 460 lb-ft of torque.
The ratings elevate the bar for the C7 Corvette as the highest standard power ever produced. Even better, the power continues to be delivered as efficiently as possible: The Stingray is expected to average 26 mpg on the highway.
The 2014 Corvette Stingray's LT1 engine takes its place as the fifth generation of the small block engine family - a legacy which began in the Corvette in 1955. The Corvette's original 4.3L 265-cubic inch carbureted engine was rated at 195 horsepower. Five short years later, the small block helped the Corvette secure its first victory at the 24 Hours of Le Mans.
"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 small block chief engineer Jordan Lee in a statement announcing the power ratings.
"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 up-level engines offered by competitors."
Producing an incredible 74 horsepower per liter, the new LT1's power density triumphs that of the C6 Corvette's LS3 6.2L engine and even the C6 Z06's race-inspired 7.0L LS7. The torque it produces is comparable to that of the LS7 (up to 4,700 rpm) and its peak torque is within 5 lb-ft of the 7.0L engine.
The Stingray is expected to perform exceptionally well at all speeds, thanks to early torque generation which is sustained throughout the rpm band: 316 lb-ft is available at 1,000 rpm and 90 percent of peak torque is available from 3,000 rpm to 5,500 rpm.
Chevrolet has estimated that the Stingray will accelerate from 0 to 60 mph in less than four seconds.
The new LT1 engine has been fitted with several advanced technologies in order to help it get to its new power rating, including: direct injection, Corvette's first-ever active fuel management system, and continuously variable valve timing which supports an advanced combustion system, just to name a few.
Some additional engine features to look forward to include an advanced oiling system with oil-spray piston cooling and available dry-sump oiling, engine-mounted, camshaft-driven fuel pump to support the direct injection system, an intake manifold with "runners in a box" design that allows for high-efficiency airflow packaged beneath the Corvette's low hood line, and high-flow, four-into-one exhaust manifolds based on the design of the LS7 engine.
The all-new 2014 Corvette Stingray coupe will go on sale this fall, with the convertible available by the end of the year.
