This heavily upgraded Hennessey H700 Corvette C8 Stingray with its Herculean power output poses a real threat to extravagant supercars.

Hennessey Performance Engineering has a legacy of building some of the most powerful gasoline-powered cars in the history of automobiles. Hennessey started off by tuning various Dodge Viper models, skyrocketing the performance of their already formidable powertrains. The brand rose to fame back in 2013 after the Hennessey Venom GT based on the Lotus Elise set a new Guinness World Record for the fastest road-legal car to achieve a speed of 186 mph. Since then Hennessey has forged some shockingly powerful vehicles ranging from high-performance sports cars to pickup trucks and SUVs.

The latest and greatest product from Hennessey is a madly capable version of the already potent C8 Chevrolet Corvette Stingray that has been tuned up into a supercar-killing beast. They have named this monstrosity the H700, and today we’ll look into the factors that make the Hennessey H700 Corvette C8 Stingray a terrifyingly efficacious sports car and a custom Corvette with stock levels of build quality.

The beating heart that serves as the base of the Hennessey H700 is the 6.2-liter naturally aspirated V8 engine of the C8 Corvette Stingray putting out 490 horsepower and 470 lb-ft of torque. Hennessey then goes all out on this small-block V8, squeezing out an astounding amount of grunt from it. All the performance enhancements added to the Stingray’s stock powertrain in order to make it the hotshot H700 are covered in detail in the segments below.

Supercharging the naturally aspirated V8 motor is the foremost and paramount task Hennessey does to build up the H700 Corvette Stingray. For this, they use a high-flow centrifugal supercharger which is a special type of supercharger that makes use of natural, centrifugal force to thrust more air into the engine. This surge in airflow allows the engine to burn more fuel which then results in a significantly boosted power output.

So then how much power does the Hennessey H700 Corvette Stingray produce? More than enough to frighten you on the street and rain hellfire on a track. The stock 490 horsepower and 470 lb-ft combo is upgraded to a whopping 708 horsepower and 638 lb-ft, resulting in a power increase of 44% while torque shoots up by 37%. These figures make the H700 Corvette C8 Stingray the highest horsepower C8 Corvette and while the new stock 2023 Chevrolet Corvette Z06 outruns a Ferrari F8 to 60mph according to zeroto60times.com, the H700 further takes it up another notch.

According to KBB a base 2023 Chevrolet Corvette Stingray starts at $61,900 while the newly launched 2023 Chevrolet Corvette Z06 starts at $105,000. The Corvette Z06 gets a different powertrain compared to the base Vette. The first mid-engine Corvette Z06 ever is powered by a high-revving naturally aspirated 5.5-liter V8 that churns out 670 horses and 460 lb-ft of maximum torque. As you can see, the H700 Corvette C8 Stingray clearly dethrones the Z06 in terms of raw power output.

Cramming up 700+ horses into the Corvette Stingray necessitates the need for better cooling in the H700 Corvette. Hennessey has tackled this need by adding an air induction system with an air-to-water intercooler. In this type of intercooler, water flowing inside it makes sure that the air coming in from the supercharger is cooled and of higher density, before it is passed on to the engine. This system makes sure that the H700 Corvette stays calm on the inside while it is ripping the road apart on the outside.

This part is for enthusiasts who are worried about losing the roaring soundtrack of the naturally aspirated Stingray V8 engine as it gets supercharged in the H700. Fear not, Hennessey has got your back there too. They provide an option to equip an enhanced cat-back exhaust to the H700 Corvette C8 Stingray. This muffler makes sure that the sweet supercharger whistle is accompanied by a demonic vroom and keeps the sound of this beast dreamy and desirable.

Every H700 Corvette C8 Stingray features both ‘Hennessey’ and ‘H700’ badging and a serial numbered plaque as standard equipment. However, Hennessey allows you to choose from Blue, White, Black, Silver, and Red for the vinyl Hennessey Heritage Livery. The wheels are another component offered with multiple finishes as the lightweight 19 and 20-inch alloys can be opted in Brushed Aluminum, Satin Black, or Graphite. Hennessey makes sure that there are enough options available for you to make your H700 look truly unique.

Now for compatibility, Hennessey states that the H700 package can be fitted onto any 2020-2022 C8 Corvette Stingray Coupe. However, as the 2023 Chevrolet Corvette Stingray carries over from last year without major changes, we expect this model year also to be H700-compatible. While Hennessey has previously tuned Corvettes, including the 1000-horsepower HPE1000 C7 Corvette Z06 and ZR1 models, the H700 stands out as being the first Stingray and the first C8 Corvette to get the Hennessey treatment.

In order to ensure that the heavily-boosted H700 Corvette C8 Stingray is protected over the years as it burns rubber and smokes supercars Hennessey provides a 3-Year / 36,000-mile comprehensive warranty coverage. Moreover, Hennessey claims that the H700 package is available to order via all authorized Corvette retailers as well as directly from Hennessey itself. The brand also offers international shipping which ensures that all enthusiasts around the globe have the option to beef up their Stingray Coupes.

Cost is the final and ultimate factor that affects your decision on whether to equip your C8 Stingray with the H700 package. Hennessey offers two variants of the package and the first one is a power-only package worth $34,950, consisting of just the supercharger upgrade along with the warranty coverage. The full-fledged Hennessey experience that also includes the rest of the upgrades is priced at $49,950. These figures combined with the base Stingray’s price cost just a little above the price of a new 2023 Corvette Z06 and that makes the H700 Corvette C8 Stingray a worthy option.
