Hennessey developed a comprehensive upgrade package for the regular Chevrolet Corvette C8 to dramatically increase the power of the V8. The 6.2-liter mid-engine produces 490 hp and 465 pound-feet (630 Newton-meters) of torque in naturally aspirated form, but those numbers increased significantly after installing a supercharger. The forced-induction LT2 now develops 708 hp and 638 lb-ft (865 Nm).
With an extra 44 percent horsepower and 37 percent torque, Hennessey’s H700 package “turns off” the Z06. The aftermarket specialist means it packs a lot more punch than the 670bhp and 460lb-ft (624Nm) delivered by the 5.5-litre “LT6” flat crank inside the Z06. The extra oomph was achieved by installing a high-flow centrifugal supercharger, custom air induction system with air-to-water intercooler and optional cat-back exhaust.

The horse-hungry tuner asks $ 49,950 for the H700 kit suitable for the C8 Corvette. For your money, it also incorporates a set of lightweight wheels (19-inch front, 20-inch rear) available in three different finishes: satin black, brushed aluminum and graphite. These body graphics can be available in red, silver, white, black or blue.
If you just want the extra horsepower without any other modifications, the supercharger kit retails for the more affordable price of $34,950. Hennessey adds “H700” badging and an individually numbered plaque. Customers get a three-year/36,000-mile limited warranty and the kit is compatible with 2020-2022 Corvette coupes.
John Hennessey goes so far as to label the H700 as “the most economical high-performance supercar in the world” offering a lot for your hard-earned money. There are no changes to the standard eight-speed dual-clutch gearbox, as Tremec’s automatic transmission can handle the extra load.
If you want an all-wheel-drive C8, the company with the bowtie emblem now has one with the 2024 E-Ray hybrid. Electric will follow in due course on GM’s Ultium platform.
