The 2014 Corvette Stingray Hennessey HPE500 is the entry performance package for the new American sports car. Hennessey Performance has just released a video showcasing the angry burbling exhaust note of the HPE500. Does its exhaust note sound like any entry package you've ever heard? We didn't think so.

The Hennessey HPE500 upgrade for the 2014 Corvette Stingray is intended as a mild upgrade that includes upgraded long-tube stainless steel headers, stainless steel midpipes, and high flow cats. All components will be professionally installed to your new Corvette Stingray and will receive HPE engine management calibration and dyno tuning to make sure everything works as it should. Power is rated at 507 hp (HPE507 just sounds awkward), 518 lb.-ft. of torque, and will be capable of accelerating from 0-60 mph in just 3.8 seconds. Other hardware include a set of Brembo carbon ceramic brakes, a Penske adjustable suspension upgrade.

Exterior-wise, the Hennessey HPE500 Stingray will get a carbon front lip, side sills, a carbon rear lip spoiler, and a Hennessey H10 Monoblock Wheel upgrade wrapped with Michelin Pilot Super Sport Tires. What's more, a custom interior leather upgrade with carbon trim as well as carbon fiber door sills will be available as well. Of course, as per Hennessey Performance standard M.O., the HPE500 Corvette Stingray will come with a 3 year / 36,000 mile warranty.

In the video shared by Hennessey Performance, the 2014 Corvette Stingray HPE500 showed how the new HPE hardware worked in harmony to the Corvette Stingray's design. A dial switch on the console allows the driver to select different driving modes, which demonstrates just how dramatically the engine note of the HPE500 can change between touring, sport, and track settings.

Beyond the 2014 Corvette Stingray HPE500, Hennessey also offers the HPE600, HPE600 Supercharged, HPE700 Supercharged, HPE800 Twin-Turbocharged, and HPE1000 Twin Turbocharged. In maximum HPE1000 guise, the Hennessey designs a custom balanced and forged engine with twin ball bearing turbochargers, forged aluminum pistons, forged steel rods and crankshaft, Custom HPE camshaft, high flow cylinder heads, fuel system upgrade, stainless steel inlet pipting, dual wastegates, electronic boost controller, intercooler, dual air induction filter, stainless steel turbo downpipes, and stainless steel exhaust. How much power will the HPE1000 put down? You guessed it-- 1,000 hp.

Obviously, Hennessey's reputation precedes the HPE500 and we know the company is capable of outrageous tunes. Without further ado, check out the video of the Hennessey HPE 500 2014 Corvette Stingray below:
