This time last year, Hennessey Performance was already promising a 1,000 horsepower C7 Corvette, even before anyone could get their hands on a stock version. Well, this isn’t that car, but it sounds just as manic and is aptly named the HPE700 Twin-Turbo.
Hennessey has fitted the stock 6.2L C7 with a pair of 62mm turbochargers, integrated dual wastegates, an intercooler with twin blow-off valves, and reworked piping. All in all, these engine mods shoot performance up to 707 horsepower, and 661 lb-ft of torque, fed through either a 7-speed manual or 6-speed automatic box. A standing start from 0-60 is achieved in a lightning-quick 2.9 seconds, dispensing of the quarter mile drag in just 10.5 seconds at 135.4 mph.
To keep this monster plastered to the ground, the vehicle comes fitted with Hennessey’s CarbonAero package, which includes a carbon-fiber front splitter, side sills and rear spoiler. This adds to the aggressive look of the C7, along with the firm’s lightweight H10 alloy wheels that shave over 19 lbs. of unsprung weight.
Retailing at $120,000, the HPE700 Twin Turbo is effectively double the price of the car it’s based on, a $54,000 Stingray 3LT Z51, which makes it quite expensive. But for a car designed to take the fight to the Aventador ($397,000) and MP4-12C ($239,000), it’s a bargain. They’re only building 24 of these bad boys; good luck reserving one.
