The all-new 2014 Corvette Stringray features the fifth generation of small block engines in the Corvette family dating all the way back to 1955. The LT1 6.2-liter engine cranks out 460hp and 465lb-ft of torque with the performance exhaust package (without it the car is rated at 455 hp and 460lb-ft.) The engine is mated to a standard 7-speed manual, an industry first for a U.S. car. It's the highest ever standard power rating for a Vette.
The C7's LT1 has greater power density than its C6 cousin's LS3 6.2-liter engine and produces comparable torque to the LS7 that powers the outgoing Z06. But this bad boy doesn't just have the capability to go fast, it does the job in an estimated 0-60 time of 4-seconds. When can we drive one?
The Stingray achieves its higher output thanks in part to direct injection and continuously variable valve timing. These also support the advanced combustion system, which with the direct injection, ensures a more efficient fuel burn. The direct injection is also responsible for keeping the combustion chamber cooler, allowing for higher compression ratios.
Other engine features include: an advanced oiling system with oil-spray piston cooling, allowing for an available dry-sump system; a four-into-one exhaust; a new intake manifold and an engine-mounted camshaft-driven fuel pump (supporting direct injection).
Active fuel management, also known as cylinder deactivation, is used on the new Stingray for the first time in Corvette production. This helps to save fuel by shutting down half the engines cylinders in light- load driving. The deactivation of the cylinders is seamless, causing the driver to never be aware of the system actually working. Emissions are also reduced by about 25 percent, according to Chevy.
On sale this fall, the Corvette Stingray is a long time coming. Continuing the Corvette legacy, this Ray will also be made available in a convertible by the end of this year.
