Default Official - 2014 Corvette Stingray Cranks Out 460 Horsepower

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.

Well that's disappointing.

In the end it will still be fast as hell with the power under the range it has. VERY flat TQ curve.

For all intents and purposes, better torque than the LS7. Nice work.

Don't forget to read the part about that being with the 460 HP and 465 Torque is the optional exhaust. Without that option you are back to the 455/460 that we were talking about all last week.

A LS7 dyno graph (not from gm.com so I'm not 100% sure if this is straight from GM or not)

460hp available in the base C7 is a lot of power.....people should be pretty pumped about that. 60hp more then when the C6 debuted puts this as a nice hp gain from generation to generation.

The torque curve is beautiful. Consistent drive out of corners.

The C6Z also has a great TQ curve.
