You don’t hear many people complaining that the C7 Corvette isn’t fast enough, and for good reason. The lowest priced Stingray rockets from zero to 60 mph in an eye-watering 3.8 seconds. But the folks at Hennessey Performance like to do better, so they strapped a few bits on this 2015 C7 Stingray, reconfigured its brain, and shot it down the drag strip.
It did quite well. Equipped with GM’s eight-speed automatic transmission and drag radial tires, the Stingray leapt its first 60 feet in a swift 1.77 seconds, hurdled through 60 mph in 2.9 seconds, and cracked the quarter mile in 10.97 seconds at a speedy 131 miles per hour.
That sporting bonnet hides quite the powerplant underneath. The C7 now features higher flow cylinder heads, an ECU tune, aggressive HPE700 camshaft, and of course a big ‘ol 2.3-liter supercharger, which cranks its muscle all the way up 708 horsepower at a shouty 6,300 rpm.
You might wonder, why tune a Stingray up around the same level as the new 2015 Corvette Z06, when you could just buy one of those? Well, because you probably won’t be able to get your hands on a Z06 for a long time. They’re a bit in demand.
No doubt about it, the supercharged HPE700 Stingray is quick. But, like the Z06, it’s also quite rare. Hennessey only built 100 versions for 2014, and doesn’t plan on lifting that hold any time soon. Given Hennessey’s penchant for retooling and upgrading Fords too, we wonder how long it takes before the newly revealed GT350R or Ford GT end up at the Texas workshop…
