 At 74 hp per liter, the ’14 Corvette Stingray 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. | |
 The ’14 Corvette Stingray’s all-new LT1 6.2L V8 engine is SAE-certified at 460 hp at 6,000 rpm and 465 lb.-ft. of torque at 4,600 rpm, with the available performance exhaust system. |
The ’14 Corvette Stingray’s all-new LT1 6.2L V8 engine is SAE-certified at 460 hp at 6,000 rpm and 465 lb.-ft. of torque at 4,600 rpm, with the available performance exhaust system, Chevrolet announced Tuesday.
The Stingray is SAE-certified at 455 hp and 460 lb.-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.
Chevrolet estimates the Corvette will run from 0 to 60 mph in less than four seconds.
“The ’14 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 hp 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% of peak torque available from 3,000 rpm to 5,500 rpm.
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.
The ’14 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.
