We were very surprised to learn that the 4th installment of the “Transformers” movie franchise from Director Michael Bay has started filming out in Monument Valley near the borders of Arizona and Utah. Joining the cast of cars to be featured in the movie is the 2014 Corvette Stingray. The race-inspired Corvette Stingray is shown

2014 Corvette Power and Torque Numbers

The 2014 Corvette Stingray’s all-new LT1 6.2L V-8 engine is SAE-certified at 460 horsepower at 6,000 rpm and 465 lbs-ft of torque at 4,600 rpm, with the available performance exhaust system. The Stingray is SAE-certified at 455 horsepower and 460 lbs-ft with the standard exhaust system. They are the highest standard power ratings ever for the Corvette, delivered with efficiency that is expected to exceed 26 mpg 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,” 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.”
At 74 horsepower per liter, the LT1 has greater power density than the C6 Corvette’s LS3 6.2L engine and even the C6 Z06’s racing-derived 7.0L LS7. It also produces comparable torque to the LS7 – up to 4,700 rpm – and its peak torque is within five lbs-ft of the 7.0L engine. That torque is generated early and sustained across the rpm band, with 316 lbs-ft available at only 1,000 rpm and 90 percent of peak torque available from 3,000 rpm to 5,500 rpm – giving the lightweight Corvette Stingray excellent acceleration at all speeds.
The new LT1 engine’s high output, and high power density and efficiency are due to several advanced technologies, including direct injection, Active Fuel Management and continuously variable valve timing, which support an advanced combustion system. Direct injection is a primary contributor to the engine’s combustion efficiency, ensuring a more complete burn of the fuel. Direct injection also keeps the combustion chamber cooler, which allows for a higher compression ratio. Emissions are also reduced, particularly cold-start hydrocarbon emissions, which are cut by about 25 percent. Active Fuel Management, or cylinder deactivation, is a first-ever application on Corvette. It helps save fuel by imperceptibly shutting down half of the engine’s cylinders in light-load driving. Continuously variable valve timing is refined to support the LT1 AFM and direct injection systems to further optimize performance, efficiency and emissions.
These technologies support the all-new, advanced combustion system, which incorporates a new cylinder-head design and a new, sculpted piston design that is an integral contributor to the high-compression, mixture motion parameters enabled by direct injection.

Update! C7 Stingray Options Bump Output to 460HP!

Earlier today, we reported that the C7 Stingray would be producing 455 hp and 460 lb.ft of torque with the standard exhaust system. However, it now appears that with the optional performance exhaust system, the LT1-powered C7 Vette will make 460 hp and 465lb.ft of torque! Check out the SAE graph at our source’s link.
