The direct injected LT1 V8 under the hood of the all-new C7 Corvette Stingray is rated at 460 horsepower and 465 pound-feet of torque at the flywheel. That is, with the optional performance exhaust, which unleashes and extra 5 hp and 5 lb-ft of torque. These numbers, while all well and good, mean little as flywheel horsepower numbers can sometimes vastly outweigh the power actually getting to the wheels.
The weight for true pavement-hitting horsepower numbers is finally over, as Edmunds has strapped the Stingray to a dyno in the first independent test of its kind. Here are the results.
First, let’s look at torque – of which the LT1 has plenty. From 2,000 to 6,000 RPM the Stingray’s 6.2-liter V8 produces no less than 350 pound-feet of torque, as we can see in the graphs in the gallery above. Topping out around 5,000 RPM, the torque hits 411 pound-feet at the rear wheels.
On the horsepower front, the story is a bit less linear. Horsepower climbs quickly between 2,000 and 6,000 RPM topping out at 411 horses - just around 1,000 RPMs after peak torque.
Edmunds also compares the Stingray to the Camaro and Ford GT500 dyno tests in the graphs above. As you can see, the Ford does a sight better than the ‘Ray. Rightfully, Edmunds is quick to point out that comparing the two isn’t really fair. They are, after all, very different beasts.
