Hennessey unveiled today its latest creation: HPE700 Twin Turbo based on the 2014 Corvette Stingray. This new supercar comes with the same 6.2-liter V8 engine found on the standard version, but Hennessey installed a twin turbo system that uses a pair of precision ball bearing 62 mm turbochargers producing 7 psi of boost pressure.
The HPE system is handcrafted and uses mandrel-bent stainless steel tubing throughout and incorporates dual turbo wastegates. Moreover, twin blow-off valves found on the intercooler’s TIG-welded aluminum plenum are prominently displayed when the hood is opened. If the standard engine delivers 455 hp and 450 pound-feet of torque, thanks to Hennessey, the power delivered now is 707 hp and 661 pound-feet of torque.
The standard 2014 Corvette Stingray sprints from 0 to 60 mph (96 km/h) in 3.8 seconds, while the new Hennessey HPE700 Twin Turbo zooms in just 2.9 seconds (1/4 mile in 10.5 seconds @ 135.4 mph or 218 km/h). Top speed is in excess of 210 mph or 338 km/h. As you can see from the photos, the HPE700 Twin Turbo 2014 Corvette Stingray also comes with a new CarbonAero carbon-fiber front spoiler, side sills and a rear lip spoiler, that provide additional overall downforce.
Pricing starts at $120,000 and includes the base Corvette Stingray with 3LT and Z51 factory options. Hennessey plans to produce only 24 examples of the HPE700 Twin Turbo Corvette for the 2014MY so you’d better hurry up if you want one!
