We kinda saw this one coming.
Hennessey introduced the supercharger performance upgrade for the Corvette C8 Stingray a month ago and has now published a video to show just how much faster it is than the standard car.
The results of the drag and rolling race are not surprising. To produce the H700, Hennessey bolts a high-flow centrifugal supercharger to the engine and includes an air-to-water intercooler. This boosts the output of the 6.2-liter LT2 V8 to 708 horsepower and 638 lb-ft of torque. The standard C8's naturally aspirated V8 produces 490 hp and 465 lb-ft of torque, so this was a massacre you can easily see coming.
The question is not about whether the H700 will win but rather by how much it will win.
Hennessey ran an H700 and a standard 'Vette on the same day, in the same driving mode, with the same amount of fuel in the tank to keep things as fair as possible. The drivers didn't use launch control, instead revving up to 1,000 rpm while holding the brake pedal pressed down.
As you can see from the inside of the standard Corvette, the H700 runs away and keeps going. In the rolling race, the cars were kept in automatic mode, and once again, the H700 opened up a sizeable gap.
The standard car is already a beast. We know from previous drag races that the new mid-engine layout provides enough traction to beat a car with a 300-horsepower advantage. We know the Z06 is a true supercar beater, and we'd love to see the H700 go up against America's Ferrari. The H700 trumps even the Z06, with its NA flat-plane V8 producing 670 hp.
According to Hennessey, the H700 is the best-value high-performance supercar in the world. If you only want the power boost, it will cost $34,850. Based on advertised pricing on Chey's website, you can get an H700 for as little as $100k. The Z06 starts at $105k. These figures are unrealistic, though. Supply remains scarce thanks to continued struggles at Chevy's Bowling Green factory, so Corvette values are incredibly skewed.
Also, the H700 is not really a Z06 rival. It may be as fast in a straight line, but the Z06 is so good because of its naturally aspirated engine, which will happily spin all the way to 8,400 rpm. The ability to cling to a gear makes it infinitely more fun on the track and a mountain pass.
Still, Hennessey needs to make the H700 against Z06 happen so we can get an answer.
