The 2014 Corvette Stingray’s all-new LT1 6.2-litre V8 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. With the standard exhaust, the figures are 455 horsepower (339 kW) and 460 lb-ft (624 Nm). They are the highest standard power ratings ever for the Corvette, delivered with efficiency that is expected to exceed 26 mpg on the highway.
At 74 horsepower per liter, the LT1 has greater power density than the C6 Corvette’s LS3 6.2-litre engine and even the C6 Z06’s racing-derived 7.0-litre 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.
