After the power numbers for the 2014 Chevrolet Corvette Stingray were discovered in a PDF file this past Friday, Chevy has announced the official power figures that its direct-injected 6.2L V8 LT1 produces. They are an SAE-rated 455 horsepower (339 kW) and 460 lb-ft (624 Nm) with the standard exhaust system.
However, those who opt for the performance exhaust system will see a power bump to 460 horsepower and 465 lb-ft — 30 hp more than the outgoing base Corvette — while highway fuel economy is expected to exceed 26 mpg. Acceleration to 60 mph is expected to be less than four seconds, and the near-flat torque curve promises to give the naturally-aspirated V8 engine the push it needs to accelerate the Vette quickly in just about any gear: 316 lb-ft is already available at 1,000 rpm, and 90 percent of peak torque can be found between 3,000 and 5,500 rpm.
At 74 horsepower per liter, the all-new 6.2L LT1 has greater power density than the C6 Corvette’s LS3 6.2L engine and even that of the amazing 7.0L LS7 found in the Z06 and 427 Convertible. In fact, Chevy touts that the peak torque of the new LT1 is within 5 lb-ft of the LS7.
With time, we may see a power increase from the LT1, along with the introduction of multiple variants of the new Gen V Small Block engine family, such as the recently-trademarked LT5, LTX, and L88 engines.
