2014 Corvette Stingray Cranks Out 460 Horsepower

SAE certifications confirm new Corvette has most powerful standard engine ever

The Corvette Stingray's LT1 6.2L V8 produces SAE Certified 460 horsepower and 465 lb-ft of torque with the performance exhaust.
LT1 provides 90 percent of the peak torque from 3,000 rpm to 5,500 rpm for quick acceleration at a wide speed range.
The LT1 has the highest horsepower ever in a standard Corvette.


DETROIT – 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.

Additional engine features include:


  • 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
  • Intake manifold with “runners in a box” design that allows for high-efficiency airflow packaged beneath the Corvette’s low hood line
  • High-flow, four-into-one exhaust manifolds based on the design of the LS7 engine.

Small Block legacy


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.

The change from C5 to C6 brought standard HP above that of the C5 z06. I was hoping for the same progress after such a long run for the C6. The Camaro is not far behind, and neither is the 5.0 in V8 base versions. I won't mention the GT500 or ZL1. Let's see if that flat torque curve can deliver some numbers.

Not quite - the C5Z06 ended it's run with a 405HP rating. The LS2 offered in the 2005 C6 was rated at 400HP. Maybe we'll see an LT4 with > 505HP in a couple of years.

I'm not sure that the base Corvette is expected to rival the performance of the ZL1 or the GT500. Back in the C2 days, the standard engine was rated from 250HP to 300HP, and there were more powerful engines available in the Chevy line up that would smoke the base engine Corvette.

I think we'll have to wait for the Z06 and the ZR1 (if we get one) to see the full performance of the car.

If Chevy could coax 500 horsepower out of the LT1 (and they probably can), they wouldn't. They have to keep something in their pocket for excitement down the line. There is a lot left on the table for future development to reignite sales when they need to. That's what it's always been about. Think about all the possibilities. 460 is a good start for the C7, but when did Chevy ever sit on a horsepower rating for more than a few years before offering...more.
 
Vette Power

460 hp is just fine! What the car needs is real hook-up without the thing fighting itself with the traction control and all that. Tires are a major part of it as well as weight shift on takeoff. It doesn't take much for a C6 to break 'em loose in 3rd doing 50 already. I don't want 4-wheel drive or mid-engine in the Vette, but traction is the biggest restriction. The best upgrade would be a Bob Bondurant training of the driver - gotta be worth 100 hp or so.
As for the Z cars, that's a lot more traction needed!

So if we are comparing apples to apples, the base car should have 500 hp. For the same money, you can get a zl1 or GT500 with greater numbers. As tradition holds, the GT500 can't hook up due to its nose heavy heritage and undersized rear tires. On the track, it is all about traction and shifting if you drive a manual. In marketing to the non-track public, it is about the numbers. And yes, the base C6 rivaled what was the GT500 before this model of the GT500. It did so with weight, weight distribution and traction. Will that formula work with the 200 mph GT500? Corvette is supposed to be superior to the Mustang and Camaro in performance, not just in name.
 
What I find amusing is back in 02 the Z06 had 405 hp. and we all went wild.......and like I read in a magazine...now days my hedge trimmer has 400 hp and my lawn mower has 500 hp....lol.........its unreal what the potential in these new small blocks are compared to the old days......as for me and my house 450 hp is enough to scare this old man and I'm currently happy with that.....I would like to see what 638 feels like though......hmmmm.

638 is a wild ride. Hard part is hooking up. I put a procharger on my z16 and it was amazing in midrange. Downshifting was a neckbreaker. I'm a lousy shift guy. Best I could do was 11.6 in the quarter. After that I could not go back to anything less. So 460 seems pretty pedestrian to me.
