Chevrolet has just officially announced that its all-new 2014 Corvette Stingray will produce a monstrous 460 horsepower and 465 lb-ft of torque with the Stingray's available performance exhaust system fitted to the car. C7 Corvettes equipped with the standard exhaust system are not far behind, with 455 horsepower and 460 lb-ft of torque. Both numbers are SAE-certified.
The ratings for 2014 Corvette represent the highest standard power ever produced. In addition, the Stingray is also more efficient, and is expected to be rated at roughly 26 mpg on the highway.
Featuring fifth generation of the small block engine family, the 2014 Corvette Stingray's LT1 engine carries on a legacy that started with the Corvette in 1955. The Corvette's original 4.3L 265-cubic inch carbureted V8 was rated at 195 horsepower, and five year later the engine 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.
"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."
With 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 torque generation 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 says the Stingray will rush from 0 to 60 mph in less than four seconds.
The new LT1 engine has been fitted with several advanced technologies to aid it in achieving 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 is set to go on sale by the fall, with the convertible available by the end of the year.
