Sealy, Texas (February 27, 2024) Hennessey, the Texas-based hypercar manufacturer and high-performance vehicle creator, has supercharged the widely sought-after Corvette C8 Stingray hard top convertible (HTC), America’s premier mid-engine sports car. The new Hennessey Supercharged ‘H700’ Corvette C8 Stingray, fitted with a muscular belt-driven blower, vaults the standard mid-engine Stingray HTC to exotic levels of power and torque to rival the celebrated Chevrolet Corvette C8 Z06.

The eighth generation C8 convertible is shipped with a mid-mounted LT2 6.2-liter V8 engine. The naturally aspirated engine delivers 490 bhp and 465 lb-ft of torque in stock configuration. To unleash the untapped potential of the American small-block, Hennessey’s Texas-based team installs a high-performance supercharger engineered to fit in the HTC’s compact engine compartment, an air induction system with an air-to-water intercooler, and an enhanced cat-back exhaust system.

Completed with recalibrated high-performance engine software, the ‘H700’ boasts an explosive 708 bhp and 638 lb-ft torque – a 44 percent increase in horsepower and 37 percent more torque over the factory rating. In terms of engine output, Hennessey’s supercharged ‘H700’ Corvette C8 Stingray bests Chevrolet’s flagship C8 Z06, which delivers a factory rated 670 bhp and 460 lb-ft from its naturally-aspirated 5.5-liter LT6 flat-plane crank V8.

John Hennessey, founder and CEO: “Our supercharged C8 Convertible boosts America’s favorite sports car to extraordinary performance levels. We’ve unleashed the power that Chevrolet left on the table, boosting output by more than 200 bhp. Few cars, especially at this price, can deliver this level of power, acceleration, and engaging open-air driving experience alongside the Corvette’s distinctive V8 roar.”

The Hennessey Supercharged ‘H700’ Corvette C8 Stingray upgrade package includes the supercharger with air-to-water intercooler, high-flow air induction system, upgraded fuel system, cat-back exhaust system, Hennessey engine and transmission calibration, and all necessary gaskets and fluids. Optional upgrades include an active-valve exhaust system, forged 19-inch alloy wheels, and a ‘Hennessey C8 Heritage Livery’. The optional Lightweight Street Wheels are offered with a gloss black, matte gunmetal, or satin silver finish, while the striking vinyl Hennessey Heritage Livery is offered in Blue, White, Black, Silver, or Red. All packages feature ‘Hennessey’ and ‘H700’ badging and a serial numbered plaque.

The Hennessey ‘H700’ Corvette upgrade is available on all 2020-2024 Chevrolet C8 Corvette Stingray Coupes and HTC models. Hennessey’s ‘H700’ package, backed by a comprehensive three-year / 36,000-mile limited warranty, is available from authorized Corvette retailers, or directly from Hennessey at +1 979.885.1300 or HennesseyPerformance.com.
