Hennessey Performance has announced a potent new supercharger option for the eighth-generation Chevrolet Corvette.
The Hennessey H700 package delivers a 44 percent boost in horsepower, plus a 37 increase in torque, compared to the standard C8 ‘Vette.
Hennessey has tuned the mid-engined sports car to produce 708 horsepower, with an accompanying 638 lb ft of torque.
This makes the H700 even more powerful than Chevrolet’s own high-performance Z06 model. The Z06’s naturally-aspirated 5.5-l flat-plane-crank V-8 engine ‘only’ musters 670 horsepower and 460 lb ft.
Supercharged performance
The regular C8 Corvette’s 6.2-l V-8 delivers a respectable 490 horsepower and 465 lb-ft of torque. However, such an output is hardly sufficient for an extreme tuner such as Hennessey.
Unlocking the big power gains is a centrifugal supercharger. This is accompanied by a high-flow air intake system, with the engine exhaling through a new sports exhaust.
Other changes include the fitment of an air-to-water intercooler to keep charge temperatures low, along with Hennessey’s own bespoke ECU calibration.
Each completed car benefits from chassis dynamometer testing, plus a 500-mile road test, before being handed over to a customer.
‘The best value supercar in the world’
Hennessey’s H700 package includes a set of 19-inch (front) and 20-inch (rear) alloy wheels, with buyers also able to specify a Heritage Livery finish.
Opting for the full H700 experience will cost $49,950 (approx. £41,500), with the engine-only option requiring $34,950 (£29,000). A three-year, 36,000-mile warranty is standard, and Hennessey will sell the car around the world.
John Hennessey, company founder and CEO, said: “The stock C8 Corvette Stingray is an extraordinary sports car, yet Chevrolet left some V8 performance on the table. Our exciting H700 supercharger package integrates seamlessly with the eight-speed dual-clutch gearbox, and our exhaust upgrade sounds much more aggressive than stock.
“Considering that our power and torque surpass the factory Z06, the Hennessey H700 is arguably the best value high-performance supercar in the world.”
