The most impressive model in Hennessey’s line-up at this point is without a doubt the Venom GT , but with Hennessey, the best always seems to get one-upped by their next project. The vehicle ready to take on the challenge is the new HPE800 Concept based on the new McLaren MP4-12C . As its name suggests, the HPE800 will get a power upgrade to the tune of 800 HP - up from the current 592 HP. Next to this, the tuner will also be offering a more aggressive aero package, new wheels, and interior changes.
Hennessey was able to massage more power out of the McLaren’s 3.8-liter twin-turbo V8 by adding an upgraded intercooler system, air intake system, and ball-bearing turbochargers, as well as ECU updates and, of course, a new Hennessey titanium exhaust system. These updates will allow the MP4-12C to push out the aforementioned 800 HP.
With a power update like the one provided by Hennessey, the super car also had to get a mini makeover for both the exterior and interior to balance itself out. For this, the tuner installed a new, center-positioned frontal air inlet with hood extractor that will allow room for larger heat exchangers for improved engine intercooling as well as transmission cooling. The new set of wheels are wrapped in Michelin Pilot Super Sport Tires, while the interior combines carbon fiber, Alcantara, and leather for a luxuriously supple feel.
