2014 Chevrolet Corvette Stingray

The 2014 Corvette Stingray’s all-new LT1 6.2L V-8 engine is SAE-certified at 460 horsepower (343 kW) at 6,000 rpm and 465 lb-ft of torque (630 Nm) at 4,600 rpm, with the available performance exhaust system, Chevrolet announced today.

The Stingray is SAE-certified at 455 horsepower (339 kW) and 460 lb-ft (624 Nm) 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 5 lb-ft of the 7.0L engine. That torque is generated early and sustained across the rpm band, with 316 lb-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.

Chevrolet estimates the Corvette will run from 0 to 60 mph in less than four seconds.

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 in the air-fuel mixture. That’s achieved by precisely controlling the mixture motion and fuel injection spray pattern. 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.

The 2014 Corvette Stingray’s LT1 engine is the fifth generation of the Small Block engine family, which debuted in the Corvette in 1955. It displaced 4.3L (265 cubic inches) and was rated at 195 horsepower, drawing air and fuel through a four-barrel carburetor. Five years later, Small Block power helped Corvette secure its first victory at the 24 Hours of Le Mans.

In 2012, the Small Block-powered Corvette Racing C6.R beat Ferrari, BMW and Porsche to sweep the drivers’, team, and manufacturer championships in production-based American Le Mans Series GT class. These championships make Corvette Racing the most successful team in ALMS history, with a total of 77 class wins, eight drivers’ championships, and nine manufacturer and team championships since 2001.

The 2014 Corvette Stingray coupe goes on sale this fall, with a convertible following by the end of the year – each sharing an all-new aluminum frame structure and enhanced chassis, as well as completely new exterior and interior designs.

Stock!!! frakking WOW... without changing the displacement and offering AFM with is able to be essentially turned off and on via "Modes."


Katya was a blaze before I tuned her with 436 horsepower and 428 lb.-ft. of torque.. this sexy beast will be even more phenom. with 24 more HP and 37 more lbs of push. Even more attractive is that me getting one will accompany an almost immediate thrift to my Tuner and some quick bolt on goodies. 460 on its way to 500HP for about $500 is a given.

With exception to the penalty of overseas regs.. the U.S. CTS would do even better with this over the TTV6... Save the TTV6 for the FWD based vehicles in varying trim levels.. eg.. XTS-VSport 420HP.. SRX 420HP.. Lacrosse, Regal Acadia, Enclave 380HP and Impala and Traverse 370HP.. or something along those lines.


On a side.. The S/C LT1 is gonna make the LSA look like a biatch

No Doubt... U are getting almost 400lbs at fuckin LAUNCH... This will require either all nannies on.. or a driver with experience to push off the line without having a new pair of shoes every other month..

IT'S SETTLED.. 7speed Manual is my choice

Well considering that it doesn't hit lots until Sept... I'm not gonna get it until Feb or March because it would sit in the garage for damn near 6 months before I was really able to drive it. If only I lived in Texas, Cali or even Miami

And too many "experts" say the Chevy small block is low tech.

I say, candidate for best engine family ever.

Looking at that dyno chart I'm willing to bet that without AFM, this thing would be able to rev past 7k and still keep that sweet torque line to about 7200

The Chevy small block is one of the best designs since the invention of internal combustion.

Which is why it's used in everything from hot rods to Cadillacs.
