Chevrolet’s latest Corvette Z06 has certainly stirred up its share of attention this year, and for good reason. It’s supercharged, 6.2-liter LT4 V-8 is a beastly engine laying out 650 horsepower and 650 pound-feet of torque. When mated to Chevy’s all-new eight-speed automatic transmission, the Z06 is capable of hitting 60 mph in less than three seconds. But for some, that’s not fast enough.

Enter the aftermarket tuning scene. Many would argue that John Hennessey is one of the foremost tuners in the business, helping turn fast cars into ridiculous monsters.

That’s exactly the plan with this brand-new 2015 Corvette Z06, as Hennessey and his team of gearheads certainly have more power planned for its small-block V-8. But before the upgrades get bolted on, John takes the stock supercar for a test run.

There’s so much going on during this one-take video. All the gauges are doing their own dance, reading incrementally higher numbers as the car rockets down the track. That is, all the gauges except one. Take a look as the fuel gauge moves down a notch during the mile-long run, showing just how thirsty the direct-injected V-8 can be at full throttle.

John tops out at 185 mph, likely due to the Z06’s new downforce-inducing aerodynamics. Expect the extra power to help overcome that unofficial top speed and drop that 0-to-60 time. Just don’t expect the Z06 to get the EPA-estimated 23 mpg on the highway.
